Description
Technical field
The present invention relates to spray the method for anti-staining agent, spray nozzle and anti-staining agent as used herein to the canvas of paper machine.
Background technology
In the manufacturing step (papermaking step) of paper products, committed step is dry paper (moist paper), and whether well dried the quality of paper products greatly be subjected to influence.
Thereby the drying part of paper machine (drying steps) is in paper-making process very in the part and parcel.
In the drying part of paper machine, dry paper in such a way promptly, is coiled in paper on the surface of a plurality of dryer rolls that are heated usually.
In addition,, provide canvas usually, paper being pressed to the surface of dryer roll, thereby improve drying efficiency from the paper outside using under the situation of a plurality of dryer rolls.
Fig. 1 illustrates the schematic diagram that canvas in the drying section of paper machine spare uses an example of pattern (for simplicity and last canvas has been omitted in the part).
Each upside of every group of about 10 dryer roll R and downside provide a sheet of canvas A (under the situation of two canvas), and described canvas is subjected to supportings such as canvas roller K, idler roller L, canvas drier M, and form closed loop.
In addition, paper W is held between canvas A and the dryer roll R and closely is squeezed on the surface of the dryer roll R that is heated, thereby improves the drying efficiency of paper W.
Usually be disposed to the D of drier cover portion (drier pocket portion) from the water vapour of paper W evaporation, and on the basis that the drier cover D of portion ventilates finally the discharge portion from the casing that covers drying part discharge, wherein the D of drier cover portion corresponding to by dryer roll R and up and down canvas A etc. around the space.
Because the ventilation of the drier cover D of portion greatly influences the drying of paper, thereby it is very important.
Ventilation is undertaken by by hot air roll, hot air duct etc. hot-air being passed the canvas injection, but is subjected to the influence of canvas gas permeability.
Thereby, optionally use canvas with suitable gas permeability.
In addition, in single canvas system (comprising the single lamination such as dimension blue (verlan) etc.), the gas permeability of canvas is very important, and wherein paper carries out drying by being bearing in by a sheet of canvas on a plurality of dryer rolls in single canvas system.
If gas permeability is inappropriate, will produces such as phenomenons such as expansion, gas leakage, and have the problem that paper for example plays pleat or produces the paper crackle that produces.
Yet, because canvas closely contacts with paper, the paper powder that comprises in the paper, resin (pitch) etc. are transferred to the canvas surface (being referred to as the canvas outer surface in this manual) that contacts with paper conversely gradually, thereby canvas will be subjected to polluting (referring to Patent Document 1).
In addition, paper powder, resin etc. enter in the air gap (so-called canvas tissue) of canvas fabric and block this tissue and reduce the gas permeability of canvas, thereby significantly reduce the drying efficiency of paper.
In addition, have such situation, paper powder, resin that promptly is transferred to the canvas outer surface etc. further is transferred on the roller that contacts with the canvas outer surface from the canvas outer surface.
In this case, with idler roller L, the canvas drier M etc. in the roller presentation graphs 1 that the canvas outer surface contacts, and comprise the outer canvas roller N (roller that this specification will contact with the canvas outer surface is referred to as outer roller) of the outer surface side that is arranged in canvas among the canvas roller K.
If small paper powder, resin etc. are transferred to outer roller successively via canvas, then paper powder, resin etc. just are bonded to each other on the outer roller surface, and form very big lump gradually.
In addition, if accumulations such as paper powder, resin get up and be formed at the outer roller surface with stratiform, just must be by stopping paper machine with its removal, thus reduced production efficiency (referring to Patent Document 1).
In addition, have following situation, the lump that promptly forms certain size is from the outer roller sur-face peeling, and transfers to the outer surface of canvas conversely.
In this case, not only canvas has been subjected to pollution, and this moment, this lump was transferred on the paper from the canvas outer surface, thereby produces defective or cause the paper crackle in paper products.
As mentioned above, if allow transfer paper powder, resin etc. and canvas polluted gradually, then produce above-mentioned various serious problem from paper W.
In order to prevent the problems referred to above, common applying to canvas is used to prevent that paper powder, resin etc. are transferred to the anti-staining agent of canvas from paper.
Traditionally, adopted a kind of emulsion with anti-staining agent etc. directly to spray and be applied to the method for canvas.
In addition, proposed a kind of method, dripped corresponding to the oil emulsion of anti-staining agent to rotating shaft, thereby on the basis of the centrifugal force of rotating shaft, scattered and applied fine droplet (referring to Patent Document 2) from the storage liquid container of canvas upside.
Yet according to these methods, the anti-staining agent drop is easy to be blown away by the top layer air-flow (following air-flow) that the canvas motion causes, and drop can not arrive the canvas surface and worsen productivity ratio.
In addition, the drop that is blown away is attached to the parts of paper machine etc., thereby becomes big on its surface, hangs down on paper as drop (so-called polymerization drippage (drop in a lump)), thereby is subjected to remarkable situation about worsening with regard to the quality that paper products are arranged.
In addition, because the quickening of paper machine speed in recent years makes that the top layer air-flow of canvas is very violent, most of drop is rolled-up in these methods, thereby has the problem that can not effectively put on the canvas surface.
As other applying methods, often adopt following method, promptly apply anti-staining agent (referring to Patent Document 3) to canvas via the outer roller in the emulsion that immerses anti-staining agent etc. etc.
Yet, according to said method, owing to applied a lot of anti-staining agent in many cases, thereby anti-staining agent is blocked in the tissue of canvas, perhaps canvas becomes wet and by obstructions such as paper powder, and anti-staining agent can suitably not put on the canvas, thereby has significantly reduced the drying efficiency of paper.
In order to overcome above-mentioned variety of issue, the present inventor has proposed a kind of method (referenced patent file 1 and 4) that anti-staining agent is temporarily put on the outer roller of canvas and apply an amount of anti-staining agent via outer roller to canvas.
A kind of method of spraying to outer roller (particularly idler roller) by fixed spray nozzle has been proposed, method of being undertaken by movable spreading nozzle and the method (especially with reference to patent documentation 1) of being undertaken by the elongated spreading nozzle.
Yet, according to the distributing method that is undertaken by fixed spray nozzle, under the situation that outer roller length increases, anti-staining agent is tended to intersperse among more near on the part of outer roll end, thereby there is following situation, promptly must be easy on the whole surface of outer roller, carry out uniformly dispersing.
In this, elongated spreading nozzle and movable spreading nozzle can optionally be determined the quantity of nozzle and slippage width and carry out uniformly dispersing to the whole surface of outer roller.
Yet, according to the distributing method that is undertaken by the elongated spreading nozzle, use owing to chemicals carries out hundreds of times of dilutions by water, thereby compare with movable spreading nozzle, there is the trend of the sprinkling amount increase of anti-staining agent.
In addition, because chemicals intersperses among the two end portions of the discontiguous outer roller of canvas, just have following situation, promptly chemicals has problems in these part accumulation.
In this,, can not produce the problems referred to above according to the distributing method that is undertaken by movable spreading nozzle, and have can the uniformly dispersing anti-staining agent advantage.
In addition, can freely adjust type (for example, single fluid nozzle or two-fluid spray nozzle), the dispersion volume of the nozzle that uses, sliding velocity of nozzle etc., and it is suitable for suitably spraying chemicals.
In the case, if use single fluid nozzle as spreading nozzle, it is too big that dispersion volume becomes, and produce above-mentioned variety of issue.Thereby, adopt two-fluid spray nozzle usually as spray nozzle.
Yet, under the situation of using two-fluid spray nozzle,, roll at the basic last differentiation length of schooling product of the top layer of outer roller and canvas air-flow, thereby exist chemicals not arrive the situation of outer roller because the kinetic momentum of the chemicals that is sprayed is very little.
Thereby, the present inventor proposes liquid distribution with preventing the fluid device that splashes, its upstream side and downstream at the chemicals injection nozzle forms gas curtain and cuts off the top layer air-flow, thereby spray chemicals by therebetween space, with as being used to prevent chemicals such as the above-mentioned device of rolling (referring to Patent Document 1).
Yet, in said apparatus, especially under the very high situation of the paper speed of paper machine, exist gas curtain must not cut off the situation of top layer air-flow, but disturbance top layer air-flow greatly on the contrary.
In these cases, chemicals is rolled by the air-flow of disturbance more tempestuously, and has the danger that can not apply scheduled volume, and produces such as problems such as above-mentioned polymerization drippages.

The specific embodiment
Based on accompanying drawing, below will to according to the present invention to the paper machine canvas spray and apply the method for anti-staining agent, spray nozzle and anti-staining agent describe as used herein, list file names with its preferred embodiment.
(about spraying and apply the method for anti-staining agent)
Fig. 2 is the view of contact original position between explanation canvas outer surface and the outer roller.
Fig. 3 illustrates the schematic diagram that sprays the state of anti-staining agent when observing from the side from spray nozzle to the contact original position.
Anti-staining agent spray method according to the present invention is characterised in that, anti-staining agent T sprayed to the outer surface of canvas A and the contact original position C between the outer roller B in slippage spray nozzle S.
In the case, contact original position C at first contacts the position of outer roller B corresponding to the outer surface around the canvas A of operation with closed ring, and corresponding to Fig. 2 bend shadow positions.
In the accompanying drawing, canvas A shifts to downside from upside at a high speed, and outer roller B rotation at a high speed corresponding to moving of canvas A.
Thereby, on the direction of Fig. 3 hollow core arrow, produce the top layer air-flow at canvas A near surface, and on the direction of outer roller B near surface dotted arrow in Fig. 3, produce the top layer air-flow.
As shown in Figure 3, spraying according to the present invention and applying in the method for anti-staining agent, anti-staining agent T sprays to contact original position C from spray nozzle S.
When spraying in the manner described above, anti-staining agent T is sprayed by the top layer air-flow carrying of canvas A and outer roller B.
On the other hand, owing to produced the top layer air-flow of outer roller B, anti-staining agent T is assembled by two top layer air-flows and can arrive contact original position C exactly under the sprinkling state.
Certainly, anti-staining agent T is subjected to effectively applying, and can not splash in very wide scope.
When conventional spray position Sa sprays, anti-staining agent T is cut off by the top layer air-flow (dotted arrow) of outer roller B, and rolls a part of anti-staining agent T, thereby anti-staining agent T can not put on outer roller B effectively.
Reduce part in order to remedy this productivity ratio, for example,, just increased the sprinkling amount of dilution water and the canvas of exceedingly having got wet if in the sprinkling of being undertaken by the elongated spray nozzle, increase the sprinkling amount of anti-staining agent T.
According to the present invention, because the collision area between the top layer air-flow of the top layer of outer roller B air-flow and canvas A sprays anti-staining agent T, the top layer air-flow has obtained positive utilization conversely.
In other words, atomize reaches gathering, and this can make anti-staining agent T arrive contact original position C, and can be not rolled-up.
In the case, will describe sprinkling according to the present invention and the principle that applies the method for anti-staining agent.
Become according to sprinkling of the present invention and the method construct that applies anti-staining agent: spray anti-staining agent from the contact original position of above-mentioned spray nozzle between canvas outer surface and outer roller, make anti-staining agent be attached on the outer roller and by utilizing anti-staining agent to be transferred to the fact of canvas and anti-staining agent is put on canvas from outer roller.
As shown in Figure 1, canvas A contacts a plurality of (for example at about 80-100 ℃) dryer roll R that are heated via paper W pressure, and is directly heated by canvas drier M on the other hand and drying.
Thereby canvas A advances under the condition of high temperature, and the idler roller L that is in contact with it and outer canvas roller N (that is, outer roller) always be transmitted heat via canvas A from dryer roll R and canvas drier M, and rotates under the condition of high temperature.
When as mentioned above when the outer roller of high temperature sprays and applies anti-staining agent, moisture extra in the anti-staining agent is evaporated, yet wax, wet goods in the anti-staining agent are melted by heat, thus its reduced viscosity, and intersperse among the outer roller surface and form oil film.
In addition, as by roller paint being put on the wall, the part oil film is transferred on the whole outer surface of canvas A from outer roller, thereby can realize wet goods is uniformly applied to the outer surface (paint roller effect) of canvas.
In addition,, thereby on the canvas surface, effectively form thin oil film because an amount of wet goods only evenly is applicable to the top layer part of canvas outer surface under the condition of high temperature, and the tissue of can not get wet canvas or obstruction canvas.
Owing in canvas, formed oil film in a manner described, just be enough to effectively prevent that paper powder, resin etc. from shifting from paper.
In addition, because wet goods is only transferred to the top layer part of canvas in the manner described above, thereby can be corresponding to any canvas, such as the canvas that is generally used for paper machine, promptly obtain plain weave, two-layer fabric, treble cloths, needle-penetrating, screw type, top layer across type (surfacelayer span type) etc. by combination monofilament, many fibrils etc.
In other words, as previously mentioned,, be equal to or less than 20000cm having gas permeability according to conventional method
3/ cm
2In the canvas of/min, the wet goods of paper powder, anti-staining agent often causes canvas to block, and perhaps absorbs extra moisture, thereby significantly produces the trend that becomes wet of being easy to.
Yet, according to the present invention because can be on the basis of above-mentioned paint roller effect and wet goods only is transferred to the top layer part of canvas, thereby even in above-mentioned canvas also can without any problem apply anti-staining agent.
Corresponding to the method for accurately replenishing the wet goods (anti-staining agent) of oil film on the basis of above-mentioned paint roller effect with suitable amount, the wet goods of wherein said oil film is slightly from the outer roller surface losses according to sprinkling of the present invention and the method that applies anti-staining agent.
Above-mentioned applying of anti-staining agent can be undertaken by the elongated spray nozzle that use has a plurality of jet holes.
Yet, as previously shown, spraying by the elongated spray nozzle under the situation of anti-staining agent, owing to usually the chemicals dilution being used for hundreds of times, just there is following situation, wet if promptly spray and canvas is become to the whole surface of outer roller simultaneously in each hole and turning, then many water transports are to canvas.
In this, in the movable spray nozzle that sprays in spray nozzle of parallel outer roller slippage, the dilute with water not because anti-staining agent is sprayed as concentrated solution become wet so suppress canvas reliably, and such structure is preferred.
Anti-staining agent sprinkling amount with respect to outer roller is changed by various factors, for example the quantity of the type of the material of paper speed, canvas and width, outer roller quantity, paper products, the dryer roll that kept by described canvas and temperature etc.
Yet,, under the situation of spraying,, can also accurately carry out above-mentioned accurate the adjustment immediately by changing sprinkling amount and sliding velocity or replacing spray nozzle by above-mentioned spray nozzle (elongated spray nozzle or movable spray nozzle) according to the present invention.
In addition, as shown in Figure 3, when the contact original position between canvas outer surface and outer roller is sprayed, there is following situation, be that part anti-staining agent (oil, water etc.) puts on canvas, yet, since this part anti-staining agent immediately with the outer roller basis, thereby can obtain by directly spraying the identical effect of effect that total amount obtains to outer roller.
In addition, can be able to dry level immediately by contact outer roller, canvas drier, dryer roll etc., not form oil film thereby can not influence on the canvas surface because the moisture in direct acting part anti-staining agent is in.
Thus, be transferred into canvas from outer roller (for example, idler roller) to the oil of the anti-staining agent of canvas transfer, its part is transferred to paper and other outer rollers (for example, canvas drier or outer canvas roller), to adhere to.
The oil that is attached to other outer rollers forms oil film on described roller surface.
Yet, if not only unidirectional continuously from canvas supply oil, and so that to a certain degree accumulation is oily, this moment, oil was transferred to canvas from outer roller conversely.
In the manner described above, the exchange of oil between other outer rollers and canvas reaches balance, and keeps oil film to remain on its surperficial state with fixed thickness.
In addition, the oil that is transferred to paper also finally shifts out paper machine with paper by paper bearing.
Thereby, must be with such degree to outer roller anti-staining agent without interruption.
As mentioned above, under the state that sprays an amount of anti-staining agent (wet goods), if anti-staining agent is sprayed to an outer roller, then oil film not only is formed on this outer roller, and is formed on other outer rollers.
In addition, consequently, can protect the pollution of paper powder that all outer rollers avoid being caused by paper, resin etc.
(about the sprinkling position of anti-staining agent)
According to based on sprinkling of the present invention with apply the method for anti-staining agent, itself and conventional art difference are, it can rationally utilize above-mentioned top layer air-flow, and conventional art is against the top layer air-flow sprinkling anti-staining agent (with reference to by Sa shown in dotted lines in Figure 3) of canvas and outer roller.
In other words, make anti-staining agent arrive the contact original position exactly, can realize that (via outer roller) reliably applies the purpose of an amount of anti-staining agent to canvas by carrying anti-staining agent on the air-flow of top layer.
In addition, because the thought of carrying anti-staining agent has produced new advantageous effects on the air-flow of the top layer of canvas and outer roller, will be described at this.
As mentioned above, conventional spray and applying method (with reference to the Sa in the accompanying drawing 3) are tending towards being subjected to the top layer interference in air flow of canvas or outer roller, and only can be by the outer roller that is under the deep-draw state, and for example idler roller L (position S5 among Fig. 4) is actual carries out.
On the contrary, according to based on sprinkling of the present invention and applying method, as confirming ground by embodiment subsequently, even the top layer airflow influence that is tending towards being subjected to canvas etc. or slight stretch to a certain degree with the outer roller that presses canvas (in reference to Fig. 4 corresponding to outside canvas roller N S1 and corresponding to the S3 of canvas drier M) in, also can fully realize this function.
In other words, according to the present invention, can accurately spray anti-staining agent and be difficult to the outer roller that is subjected to slight stretching and realize, and can not roll anti-staining agent by conventional method.
Thereby the present invention has the advantage that can be applied to any outer roller.
In addition, as mentioned above, the anti-staining agent of spraying to outer roller (oil) is transferred to other outer rollers via canvas, forms oil film, is polluted to suppress outer roller, and prevents that further canvas from being polluted.
Thereby, providing under the situation of a plurality of outer rollers, if apply anti-staining agent to the outer roller that is positioned at canvas moving direction upstream side, then anti-staining agent (oil) is transferred to other outer rollers in the downstream, thereby can effectively prevent to pollute.
In other words, according to based on sprinkling of the present invention and applying method, preferably, outer roller that separate with paper to canvas and contact at first with it (the canvas roller N of Fig. 4 China and foreign countries) sprays anti-staining agent.
(about movable flusher)
In sprinkling according to the present invention with apply in the method for anti-staining agent, can adopt the elongated spray nozzle, yet, because chemicals uses by hundreds of times of dilutions of water as mentioned above, just exist canvas to become situation about wetting.
In this, under the situation of using movable spray nozzle, have the advantage that anti-staining agent can be sprayed as concentrated solution, dilute and need not water.
Thereby, at first will the movable flusher that be used for the slippage spray nozzle be described.
Fig. 5 illustrates the schematic diagram of the topology example of movable flusher.
In this topology example, show the situation that spray nozzle is made of two-fluid spray nozzle.
Movable flusher 1 disposes frame body 11, a left side and the right case 12L of portion and 12R, spray nozzle S, is used for fixing and moving belt 13, drive motors 14, a left side and right limit switch 15L and the 15R of slippage (moving back and forth) spray nozzle S, or the like.
Spray nozzle S fixes and is supported in the supporter 16 that promotes from brace table 13a, and this brace table 13a connection also is fixed in moving belt 13.
Be used to supply the feed pipe 17 of anti-staining agent and the air supply pipe 18 that is used to blow and be connected in spray nozzle S, and their lower end assembling and be fixed in brace table 13a.
Moving belt 13 be arranged at the cylinder in the right case 12R of portion in the tensioning mode and the cylinder that drives by the drive motors in the left case 12L of portion 14 between (any cylinder is not shown).
The left and right sides of frame body 11 is provided with limit switch 15L and 15R, and can set the slippage width of spray nozzle S by these limit switches.
In other words, in this movable flusher 1, by drive motors 14 is driven forwards to or the moving belt 13 that rearward moves up, can according to the slippage width of setting by limit switch movable flusher 1 vertically on move back and forth (slippage) described spray nozzle S.
Thereby, can prevent from chemicals is sprayed to the part that contact at the two ends place of outer roller as much as possible, and chemicals can not accumulate and not have problems in this part with canvas, these are different with previous described prior art.
In addition, be connected in the flexible duct 17a of feed pipe 17 and air supply pipe 18 and the distortion that 18a can follow cable bearer 19.
Thereby, in the process of spray nozzle S slippage, can anti-staining agent without interruption and the air that is used to blow, and spray nozzle S can spray anti-staining agent continuously in slippage.
(about spray nozzle)
Next, will describe spray nozzle.
As spray nozzle S, adopt single fluid nozzle or two-fluid spray nozzle usually.
Single fluid nozzle is configured to spray by exerting pressure to liquid, and it is characterized in that the amount of liquid that is sprayed is very big and impact (flow velocity, kinetic momentum etc.) liquid is very big.
Two-fluid spray nozzle is configured to spray by extruding liquid by blow air, and it is characterized in that this nozzle is suitable for spraying small amount of liquid, yet, impact littler relatively.
As mentioned above, spraying to canvas and applying in the anti-staining agent, material condition is to reduce the efficient of being carried out paper dryer by canvas, and must apply a certain amount of anti-staining agent, and does not make canvas become the tissue that wets and do not block canvas.
Thereby, preferably makes the water yield of dilution anti-staining agent as far as possible little, and further preferably spray the anti-staining agent of concentrated solution, and water does not dilute.Thereby, in movable flusher according to the present invention, preferably use two-fluid spray nozzle as spray nozzle.
At this moment, developed and to market supply various two-fluid spray nozzles, yet self-evident is suitably to select or the design two-fluid spray nozzle according to the sprinkling amount of anti-staining agent etc.
(about the two-fluid spray nozzle of band secondary blast)
As previously mentioned, owing to be configured to apply anti-staining agent with the top layer air-flow of canvas or outer roller according to sprinkling of the present invention and applying method, thereby even under the situation of using two-fluid spray nozzle, also can fully apply anti-staining agent, and can be not rolled-up.
Yet, under the paper speed of the paper machine situation that very highland increases and the top layer air-flow (with reference to hollow arrow among Fig. 3 and dotted arrow) of canvas etc. is very violent, the two-fluid spray nozzle that can use the band secondary blast is as spray nozzle, so that anti-staining agent arrives canvas more reliably.
The two-fluid spray nozzle of band secondary blast disposes the two-fluid spray nozzle that is used for spraying liquid (anti-staining agent) and is used for the air flow jetting mouth (secondary blast) of injection air, and be configured to from the air flow jetting mouth to the liquid jet-stream wind that sprays from two-fluid spray nozzle, and pass through the liquid that this air-flow quickens sprinkling, to spray to canvas.
Fig. 6 A and 6B are the views that the topology example of the two-fluid spray nozzle of being with secondary blast is shown, and Fig. 6 A is a perspective view, and Fig. 6 B is along the cutaway view of the line X-X of Fig. 6 A (among Fig. 6 B, two-fluid spray nozzle shown in broken lines).
Arrow illustrates secondary blow air stream among Fig. 6 B.
In this example of this structure, the two-fluid spray nozzle 2 of band secondary blast disposes two-fluid spray nozzle 3 and gas tank 4, and this two-fluid spray nozzle 3 is assembled and is fixed in by screw has roughly gas tank 4 (not shown) of C shape shape.
Two-fluid spray nozzle 3 disposes spray nozzle 31, mouth spray 32 and puff prot 33.
Two-fluid spray nozzle 3 (spray nozzle 31) is suitably selected according to sprinkling amount of anti-staining agent etc. according to the identical mode of two-fluid spray nozzle as discussed previously, to use.
In addition,, feed pipe 17 (with reference to Fig. 5) is twisted with mouth spray 32 close, air supply pipe 18 is twisted be bonded to puff prot 33 respectively via seal.
Inboard at the sidewall 41 of gas tank 4 forms depressed part, and form by the side wall ring of described sidewall 41 and two-fluid spray nozzle 3 around air flow jetting mouth 42.
Be used for supplying the secondary blast air supply pipe 21 of air via bottom and secondary blast puff prot 43 stubborn close of seal, with the supporter in the alternate figures 5 16 at gas tank 4 to secondary blast.
Though omitted explanation, self-evident, secondary blast air supply pipe 21 assembles according to the mode identical with feed pipe 17 etc. and is fixed in brace table 13a, is connected in pipeline and is inserted on the cable bearer, and be connected in compressor that is positioned at the device outside etc.
Two-fluid spray nozzle 2 with band secondary blast of said structure is connected in the movable flusher 1 shown in Fig. 5 as spray nozzle S, to use.
When from secondary blast air supply pipe 21 during to the two-fluid spray nozzle 2 supply compressed air (air that is used for secondary blast) of band secondary blast with said structure, compressed air is by secondary blast puff prot 43, packing space 44, spray from air flow jetting mouth 42 by hole 45, and form secondary blast E.
Fig. 7 illustrates the view that sprays the state of anti-staining agent from the two-fluid spray nozzle of band secondary blast.
Can be understood easily by Fig. 7, when in the future when the secondary blast E of air flow jetting mouth 42 sprays to from anti-staining agent T that the spray nozzle 31 of the two-fluid spray nozzle 2 of band secondary blast sprays, anti-staining agent T is accelerated to has the more secondary blast E of high flow rate.
In the manner described above, the two-fluid spray nozzle of band secondary blast can make by two-fluid spray nozzle fluid jet that realize, that initial impact is very weak and become stronger aspect the impact.
(about anti-staining agent)
As being used for according to sprinkling of the present invention and applying the anti-staining agent of the method for anti-staining agent, can list wax, oil or comprise the two emulsion.
Because wax and oil will be subjected to fusion on the surface of outer roller scattering, and can form the oil film with more effective water proofing property, wax and oil can preferably be used as releasing agent.
Among them, because vegetable oil, for example castor oil, vegetable seed wet goods have the set ability on canvas and outer roller of improvement, and can not harm the paper printing characteristic, preferably use vegetable oil as anti-staining agent.
In addition, because silicone oil forms the coating with stripping feature and the distinctive water proofing property of silicone oil on the surface of canvas or outer roller, preferably use the main component of silicone oil as anti-staining agent.
Various oil can be applied in the silicone oil.
Among them, because dimethylpolysiloxane--based oil (so-called " dimethyl ") is characterised in that kind is very many, and suitably select corresponding to service condition (for example material of canvas, temperature etc. when using), using, thereby it is preferred.
In addition, except above-mentioned dimethylpolysiloxane--based oil, wherein side chain or terminal groups changeably by the modified silicon oil of other organo-functional groups displacement as silicone oil to market supply, and it is preferred the use.
Based on substituting group, modified silicon oil comprises various modification types, for example, and amino sex change, epoxy sex change, alkoxyl sex change, carboxyl sex change, methanol modified, sulfydryl sex change etc.
In addition, based on displacement position, modified silicon oil is divided into side chain type, two ends type, an end type, side chain two ends type etc., and has the peculiar characteristic corresponding to combinations such as displacement position, above-mentioned modification types.
For example, when carrying out that the side chain type amino-modified silicone oil is attached to the acrylic acid dish and during the test of wiping by thin paper, compare (only carrying out a wiping just almost is wiped free of) with dimethyl, the side chain amino-modified silicone oil has the characteristic (can not be wiped free of and stay oil film by a wiping usually) that is difficult to wipe.
In other words, the side chain type amino-modified silicone oil has following characteristic, and promptly its adhesion property (anchorage) is stronger and adhere in fact securely on synthetic fiber and the metallic plate than plastics.
Can consider that this is because the organo-functional group with a plurality of side chains is attached to securely that metallic plate etc. is gone up and realize the grappling effect with respect to the surface of metallic plate etc.
If above-mentioned modified silicon oil is used for spraying and applying method according to anti-staining agent of the present invention, just adheres to them securely and be not easy to separate with them in case be attached to the modified silicon oil of canvas or outer roller.Thereby modified silicon oil is preferred.
In addition, on the basis of above-mentioned characteristic, because oil is transferred to paper and the amount of removing is minimized as mentioned above, can be thereby have so that the littler advantage of the applied amount of anti-staining agent.
Thereby, can prevent reliably such as the problem of blocking canvas etc.
In addition, on the strongly adherent basis of modified silicon oil, begin to apply modified silicon oil after the anti-staining agent and accurately be attached to canvas and form oil film in the outer roller immediately owing to follow closely, thereby have the advantage (so-called lifting) that produces the anti-soil effect very fast.
As previously mentioned, according to corresponding to set such as the quantity and the temperature of the material of canvas and width, dryer roll, the condition of the main component of kind, the paper speed of manufacturing paper products, the material that is sprayed outer roller in using and temperature, anti-staining agent (cured, oily, silicone oil and modified silicon oil) etc. determines the sprinkling amount of anti-staining agent.
(embodiment)

(changing the situation of spray nozzle sliding velocity)
In spray method according to the present invention, preferably, the sliding velocity of spray nozzle is equal to or greater than 1.5m/min.
In other words, shown in embodiment 1-3, embodiment 8, embodiment 4 and embodiment 9, compare with the situation that on the S1 of the position of Fig. 4, changes spray nozzle sliding velocity and sprinkling dimethicone (dimethylpolysiloxane--based oil), can learn, sliding velocity is more little, just has many more dirts to be attached on canvas etc.
In addition, can learn, if sliding velocity less than 2.0m/min, then small cake of sludge begins to result from canvas etc.
Can consider that if this is because the sliding velocity of spray nozzle is too little, then the oil supply reduces and consumed the oil film of outer roller too slowly.
In other words, not in the part of the surface sprinkling anti-staining agent of outer roller, oil film is peeled off in succession, and can not be effectively from this part of outer roller to canvas supply oil, and oil film can not effectively be formed on the canvas surface.
Thereby making can be from paper transfer paper powder, resin etc., and paper powder etc. is by the canvas carrying and be transferred to other outer rollers, and outer roller is polluted.
According to the problems referred to above, be appreciated that the sliding velocity influence of spray nozzle and prevent that canvas etc. from being polluted.
(adopting the situation of modified silicon oil)
This trend replaces dimethylated situation (embodiment 4 and 9) identical with using the side chain type amino-modified silicone oil.
Yet, as passing through comparing embodiment 3 and embodiment 4 (and embodiment 8 and embodiment 9) as can be known, under the prerequisite of identical sliding velocity, the anti-soil effect under the situation of employing modified silicon oil is better than adopting the anti-soil effect under the dimethylated situation, and can affirm this improvement.
(changing the situation of spraying the position)
Relatively sprinkling position S1 (embodiment 1), S2 (embodiment 5), S3 (embodiment 6), S4 (comparative example 1), S5 (comparative example 2) and the S6 (comparative example 3) of anti-staining agent are respond well by the anti-soil that sprinkling according to the present invention and applying method spray at position S1-S3 place.
On the S4 of position, can observe rolling of anti-staining agent drop.
Anti-soil effect on the S4 of position is difficult to be guaranteed, because air-flow acutely rolling of causing in canvas top layer makes not have the anti-staining agent of capacity to arrive outer canvas roller N.
At position S5 place, can observe part anti-staining agent drop and be rolled onto.
With situation that the situation of above-mentioned S4 is compared under because the amount of rolling is little, thereby can obtain better result.
But, with situation that the embodiment 5 that is spraying on the S2 of position compares under, we can say that the anti-soil effect is inadequate.Owing to rolled as mentioned above, thereby the amount that arrives idler roller L is reduced, and presents this quantity and do not reach necessary amount.
When directly being sprayed to anti-staining agent on the canvas on the S6 of position, canvas and outer roller all are subjected to severe contamination.
At this moment, anti-staining agent is acutely rolled.
Though, adopt the alternative dimethylated situation of emulsion of side chain type amino-modified silicone oil to have identical result not shown in the table 1.
In addition, substitute two-fluid spray nozzle by the two-fluid spray nozzle that adopts the band secondary blast and carry out identical test.In the case, roll though can suppress major part, canvas and outer roller are polluted in the same manner.
In other words, under the situation that canvas sprays, even anti-staining agent arrives canvas, anti-staining agent (oil, water etc.) also is absorbed then and there, and anti-staining agent can not intersperse among on the surface direction direct.
Thereby, not do not spray oil in the canvas part of anti-staining agent and be not transferred to paper and run off to it, and make conversely can the transfer paper powder, resin etc., thereby pollute (in other words, can not obtain the paint roller effect when outer roller sprays).
In addition,, can consider that paper powder etc. shift from canvas in succession owing on outer roller, do not form effective oil film, thus accumulation.
(more effective sprinkling position)
Embodiment 1, embodiment 5 and embodiment 6 have promptly wherein only changed the sprinkling position according to the anti-staining agent of sprinkling of the present invention and applying method corresponding to following situation.
From its result, can learn the following fact:
(1) oil film is formed to it and sprays in the outer roller of anti-staining agent, and oil is sent to the outer roller in its downstream via canvas, thereby effectively forms oil film, and
(2) yet, have such situation, promptly be positioned at the light contamination that is subjected to paper powder, resin etc. to its outer roller of upstream side that sprays the outer roller of anti-staining agent.
Consider above every reason,, can understand (1) easily from according to the above-mentioned sprinkling of the present invention in front with apply the principle of the method for anti-staining agent.
In addition, can consider that (2) is caused by the following fact, if promptly canvas contacts with paper pressure, as previously mentioned, part oil is transferred to paper, thereby the oil mass that is transferred to outer roller (outer roller of above-mentioned upstream side) following closely diminishes, and the anti-soil effect slightly descends.
In addition, if canvas contacts with paper pressure, the situation that exists paper powder, resin etc. to shift once in a while.
Above-mentioned paper powder etc. is transferred to paper from canvas usually, thereby in the canvas running, returned, and canvas etc. are not contaminated, yet, can consider, assembled owing to part paper powder etc. is transferred to outer roller, so outer roller is subjected to light contamination, wherein the anti-soil effect in the outer roller slightly descends as mentioned above.
Thereby, in sprinkling according to the present invention and applying method, spray anti-staining agent by outer roller that separate with paper to canvas and contact at first with it, can prevent effectively that all outer rollers from being polluted.
In addition, as passing through comparing embodiment 3 and embodiment 4 as can be known, adopt modified silicon oil more effective.
(adopting the plant oil condition)
Adopting under the situation of castor oil as the main component of anti-staining agent (embodiment 7), with adopt the identical mode of dimethyl-silicon oil condition (embodiment 1), dirt (paper powder, resin etc.) is not fixed on canvas and the outer roller, can obtain improved effect.
This be because with the identical mode of situation of dimethyl or side chain type amino-modified silicone oil, thereby castor oil is fixed on the surface of canvas or the outer roller and has formed oil film effectively, and has prevented transfers such as paper powder, resin effectively.
(gas permeability of canvas)
To the gas permeability of canvas be described at last.
In the conventional spray method,, be equal to or less than 20000cm in gas permeability as explanatorily
3/ cm
2In the canvas of/min, the wet goods that canvas is subjected to paper powder, anti-staining agent often taking place block, perhaps exists by absorbing redundant moisture to be easy to the trend that becomes wet.
The present invention can address the above problem, and can realize better effect in very wide gas permeability scope.
In order to confirm this fact, by use have with the foregoing description in have the paper condition canvas (that is 16000cm,
3/ cm
2/ min) different condition 25000cm
3/ cm
2Canvas, and be identical, and carry out the spray test of 14 day actual hours other condition enactments.
In the case, S2 (embodiment 10) and the S5 (comparative example 5) among the idler roller L adopted in the sprinkling position.
The results are shown in (table 2).
From embodiment 5, embodiment 10, comparative example 2 and comparative example's 4 result, be appreciated that spray method according to the present invention can realize good effect on the basis that gas permeability becomes quite little.
Thereby, preferably make meticulous paper.
| Embodiment 10 | S2 | 4.5 | Dimethyl | ○ | ◎ | ○ | ○ |
| The comparative example 4 | S5 | 4.5 | Dimethyl | × | ○ | △ | △ |
More than describe the present invention, but the present invention also not only is confined to described embodiment, can adopt the embodiment of other various changes within the scope of the invention.
For example, in the present invention, mainly two-fluid spray nozzle is illustrated, yet, single fluid nozzle can be used in some cases certainly.
In addition, with respect to modified silicon oil, this specification is primarily aimed at the side chain type amino-modified silicone oil, yet it only is an example, certainly adopts based on the oil on other substituent oil and other the position of substitution.
In addition, comprise that therein all canvas rollers of idler roller etc. are arranged in the canvas (interior roll shape) of inboard type, for example, can be by carrying out the present invention from canvas outside extruding canvas roller.
Industrial usability
Adopt described principle just can be applied in the broad range of techniques field of paper industry as long as the canvas to paper machine according to the present invention sprays and applies the method for anti-staining agent, use therein movable flusher and anti-staining agent, rather than be confined to paper machine.
