But, only enumerate above-mentioned invention and can't prove absolutely problem, but being continuous glass fibres, practical situation are widely used in the various uses.In recent years since, along with than the Fibre diameter of high precision management continuous glass fibre more in the past, under the situation that form in order to make continuous glass fibre be used as matrix material, further require the intensity of this matrix material higher and can realize stable performance, in many purposes, need to have than the continuous glass fibre of high-precision size in the past.Therefore, in order to make continuous glass fibre, carried out the research of the bushing that adapts with it more with such high precision size.Here, the problem that exists is a variety of causes that influences glass fiber diameter, but, the diameter of continuous glass fibre is not simple only to be decided by the dimensional precision in the aperture of nozzle opening portion, its also be subjected to high temperature under bushing through the time distortion or constitute the evaporation of material of bushing and the temperature during extraction glass fibre and the influence of various key elements such as speed or atmosphere.Therefore, need to investigate one by one very patiently to improve these key elements.The inventor in order to improve such variety of issue by discovering, as patent documentation 7, become high precision for Fibre diameter adjustment with continuous glass fibre, be all the time at the improvement of the structure of nozzle, size etc. as a rule, and whether the countermeasure of thoroughly improving also exists other approach, promptly not as being based on the bushing board position outside the nozzle, here, a kind of new technological thought is disclosed.
Summary of the invention
The objective of the invention is to, provide a kind of evaporant that bushing under the high temperature is formed to reduce, and by forming bushing securely, can be through being shaped for a long time or spinning has the continuous glass fibre of high-precision Fibre diameter with the condition of high temperature, thus the matrix material continuous glass fibre of excellent quality can be made.
For addressing the above problem the continuous glass fibre manufacturing bushing of initiating that the present invention relates to, it is a continuous glass fibre shaping bushing as described below, inside has melten glass and supplies with spatial bushing main body, possess bushing surrounding wall portion and the bushing plate that is equipped on the bottom of this bushing surrounding wall portion, and set up to be useful at the bottom surface side of above-mentioned bushing plate and supply with the many nozzles that the spatial melten glass flows out to the shaping continuous glass fibre makes from above-mentioned melten glass, it is characterized in that, be formed with overlay film except the periphery of said nozzle and the outside surface of the above-mentioned bushing plate the end face, this overlay film has used pottery, the material that in glass-ceramic and the glass material group any is above.
According to such structure, constitute the outside surface of continuous glass fibre manufacturing with the bushing plate of the bushing main body of bushing, utilization comprises the structure spare of any one material in pottery, glass-ceramic (also being called sintered glass ceramics) or the glass, the method of the outward appearance by being coated with into the overlay film shape waits and applies, on the contrary, the periphery and the end face of nozzle that is attached to the bottom surface side of bushing plate is not formed with such overlay film.
For the fact that has adopted such structure is described, the inventor has investigated from the evaporation of continuous glass fibre manufacturing with the drain board material of the outside surface of bushing, found that it may not be the evaporation from nozzle, with evaporation bigger relation is arranged on the contrary from the bushing plate around it.In addition, nozzle self by so far many improvement methods and can obtain corresponding countermeasure, but position is not in addition obviously had countermeasure.So, the present invention is based on following aspect, not at nozzle but at the outside surface of bushing plate, by using selecteed thermotolerance material to apply its surperficial privileged site, prevent from the Evaporation Phenomenon by the time under the hot environment of the bushing panel material of the outside surface of bushing plate, even the continuous glass fibre manufacturing of being exposed to the sun for a long time under the condition of high temperature also can be kept stable status and performance for a long time with in the bushing.
Used the area of the overlay film of any one above material in the above-mentioned materials group for the formation of the outside surface of bushing plate, but it is comprehensive necessarily to cover it, preferably cover and remove outside the periphery and end face of nozzle, the zone, main position more than 1/5 in the area that exposes face of the outside of bushing plate.In addition, the part that is capped may not be the successive face, and may not concentrate on a position, if only cover suitable position, preferably covers a plurality of positions, then can cover the position of evaporation especially easily expeditiously.Here, above-mentioned " zone, main position more than 1/5 " be meant, satisfies the outside surface that forms the condition of high temperature especially easily or Yin Lali effect etc. and make it at the more weak outside surface of textural intensity or be judged as the outside surface of any one condition in the most violent outside surface of evaporation.Such outside surface both can be obtained by dummy model, also can utilize actual measurements such as temperature survey to obtain.
Here, for the material of the material of bushing plate, nozzle and the nozzle structure of setting up with respect to the bushing plate, so long as have continuously and stably extract out the structure of the melten glass that is in the condition of high temperature, then there is no particular limitation to it.In addition, also there is no particular limitation for the method that the covering material that is formed by more than one materials in pottery, glass-ceramic or the glass is constructed.
In addition, also there is no particular limitation for the face shaping of nozzle, bushing plate and size.For example, can adopt drum, polygon barrel shape, the profile of the truncated cone (frustum) shape or the shapes such as profile of dome shape for nozzle form, also can be in accordance with regulations at interval or the groove of regulation, concavo-convex, dimple or projection etc. are set at random at its outside surface, so as to form easily with used ceramic, glass-ceramic or glass in the different overlay film of overlay film of more than one materials.In addition, also can utilize various medicine processing such as physical means such as sandblast or soda acid etc. that the condition of surface of its outside surface is formed the condition of surface with trickle fluctuating.In addition, also may not be plane for the bushing plate, for example also can adopt the state of having implemented concavo-convex or groove etc., the state that also can adopt with the bending of bushing slab integral.
For the equipping position of many nozzles of bushing plate, even the structure that each nozzle is provided in the optional position mutually also has no relations.For example, as the constituent parts configuration of many nozzles, both can be to be configured to three nozzle locations to form leg-of-mutton position, also can be to be configured to the position that four nozzle locations roughly form rectangular shape, and the two combined location, the position of adopting diverse other configurations.
In addition, above-mentioned structure is at the as above above-mentioned structure that has applied suitable material on the outside surface of the periphery of nozzle and the bushing plate the end face, but, this is not periphery and an end face of having a mind to get rid of nozzle, for example, for the periphery and end face of nozzle, if can fully avoid by the influence of the glass fibre of extracting out with molten state, and, on such position, form overlay film and can further bring effect, then also might as well be able to form overlay film with above-mentioned overlay film unlike material.Yet, under the situation that forms such overlay film, be preferably in and think and avoid forming such overlay film when peeling off easily.
On the other hand, the continuous glass fibre manufacturing bushing that the present invention relates to, used the position of the overlay film of any the above material in pottery, glass-ceramic or the glass as formation, except the outside surface of bushing plate, also can with as the outside surface of the bushing surrounding wall portion of the integrant of bushing main body as object.In this case, both can on the whole zone of the outside surface of bushing surrounding wall portion, form above-mentioned overlay film, perhaps also can be at suitable regional area, for example with regional area that the bushing plate links to each other on the above-mentioned overlay film of formation.Here, for example also can form overlay film on the surface of the strengthening part of construction portions such as cooling tube or fan, terminal (terminal), bushing plate etc., but, the overlay film that forms at such position, both can be the overlay film with the structure of the identical material of outside surface of bushing plate, thickness etc., also can be the overlay film of different structure.
In addition, for the formation method of overlay film, if forming the position of overlay film only is the position that is specially limited, then for the position that does not form overlay film, also can form overlay film utilizing organic materials, other mask material to cover under the state of this outside surface in advance, afterwards, utilize the method for regulation to remove mask and optionally form the state of overlay film.Perhaps, also can carry out the assembling procedure of the regulation of bushing plate as required in advance, the way only forms overlay film on the parts of regulation therein.
On the other hand, for the continuous glass fibre manufacturing that the present invention relates to for bushing, if the bushing plate is made of platinum alloy or platinum, then except high heat resistance, also can with the high temperature of melten glass under be difficult to keep higher performance aspect the reaction, therefore not only the outside surface of bushing plate but also the time dependent that can reduce internal surface change, because the deterioration of internal surface is less, so can produce continuous glass fibre expeditiously.
Here, the bushing plate is by being meant that platinum alloy or platinum constitute, the material that constitutes the bushing plate is except platinum is platinum, also can be to contain rhodium, iridium, yttrium, ruthenium, palladium, osmium, titanium, gold, molybdenum, tungsten, magnesium, calcium, hafnium or zirconium etc. in right amount, content for these coexistence compositions, if can realize regularity energy such as thermotolerance, then there is no particular limitation.Certainly, in order to realize that required effect also can be also with the material beyond platinum alloy and the platinum.In addition, as the material of the bushing plate that the present invention relates to, what adopt platinum alloy may not only be the alloy of solid solution state, also can be that microparticulate is in platinum or add ceramic member and the material of fixed sintering metal shape.
In addition, the continuous glass fibre manufacturing bushing that the present invention relates to, if overlay film is multi-ply construction, by within the limits prescribed with each rerum natura adjustment such as the coefficient of expansion or thermotolerances, the corresponding material in interface of easy and outside surface and bushing plate (perhaps bushing surrounding wall portion in addition) can be selected respectively, thereby the optimum configuration of bushing plate requirement can be constituted.
Here, overlay film is that multi-ply construction is meant that overlay film constitutes two-layer above layer state by the construction of film forming repeatedly.
For the gauge of each layer of the overlay film that constitutes multi-ply construction, composition etc., can select to form preferred composition, structure (wherein, being limited to more than one materials that used in pottery, glass-ceramic or the glass) as required.In addition, each layer need not evenly, both can be that oblique structure also can be the pinprick structure.In addition, also can in the stratified composition of structure, add aggregate arbitrarily wittingly.As aggregate, can use at preferred aggregates in aspect such as thermotolerance, the coefficient of expansion or reactivities.For example, can use glass filler, ceramic packing, glass-ceramic filler, precious metal filler etc. in right amount.In addition, can select arbitrary shape for the shape of filler.For example, can use roughly fibrous, roughly cotton-shaped, roughly latticed, roughly braid shape, roughly cryptomere, roughly coccoid, roughly broken thing shape, roughly porous insert shape, roughly polyhedral, roughly cylindric, roughly polygon prism shape, roughly tabular, roughly particulate state, roughly coniform, roughly polygonal pushing away (polygonal pushing away) shape or roughly alphabetical font column etc.
In addition, when overlay film is multi-ply construction, give distinctive performance, can realize more high-performance each layer.For example, also can be on bushing plate surface configuration with the layer of engaging of platinum alloy or platinum etc. and drain board material as emphasis, utilize the layer of the upper-layer configured densification of this layer, inhibition is from the evaporation of bushing plate, and also can be itself to dispose the layer with dense construction on bushing plate surface, layer adopts and does not allow the high layer of caducous thermotolerance thereon.In addition, for example, also can adopt and dispose the layer that has added specific filler gradually changing as the configuration thermal expansivity and suppress to take place crackle, and then layer has a stable on heating while and prevents efficiently from the such precious metal filler of the evaporation on bushing plate surface thereon.
In addition, the heat resisting temperature of overlay film depends on the kind of constructional method and construction material, need have the thermotolerance more than at least 800 ℃, more preferably has the thermotolerance more than 1000 ℃, further preferably has the thermotolerance more than 1200 ℃.In order to realize such thermotolerance, preferably burn till with this temperature more than temperature.
In addition, the continuous glass fibre manufacturing bushing that the present invention relates to, if its overlay film is in prefabricated overlay film, spraying overlay film, the immersion film-coated and vapor-deposited film any, then can form optimum configuration, can implement cheapness and the high overlay film of quality economically by the overlay film of selecting to be complementary with the bushing panel material.
Here, overlay film is that in prefabricated overlay film, spraying overlay film, the immersion film-coated and vapor-deposited film any is meant, except nozzle periphery and nozzle face, the overlay film of implementing at the outside surface of bushing plate forms by prefabricated overlay film in advance, perhaps use decompressor and injection moulding forms, perhaps formed, perhaps adopted the vapour deposition method of physics or chemistry to form having adjusted being used dipping in the slurry of bushing plate in advance by the dipping of construction surface.
For these film formation methods, it both can adopt a method, also can and use a plurality of methods.In addition, for the combination of these methods and other film formation method also without any problem.
In addition, the continuous glass fibre manufacturing installation bushing that the present invention relates to is except that above-mentioned, if the thickness of preferred overlay film below 1mm, then can form the overlay film of long-time stable structure.
Here, the thickness of overlay film is meant below 1mm, the thickness of measurement overlay film when construction or after the construction, and the observed value at the thickest thick position is as below the 1mm.
The gauge control of overlay film the reasons are as follows below 1mm is described.First reason is: if the thickness of film surpasses 1mm, the dried of construction surface and overlay film taken place easily peel off.As mentioned above, the bushing plate is made of platinum alloy or platinum, if consider the manufacturing cost of continuous glass fibre manufacturing with bushing, then the thickness of platinum alloy or platinum manufactures below the 2mm.Except continuous glass fibre manufacturing the nozzle periphery of bushing and the bushing plate outside surface the end face, by having used the overlay film more than in pottery, glass-ceramic and the glass material group any to apply, if the thickness of the overlay film of the desciccator diaphragm of this overlay film more than 1mm, then forms the hard desciccator diaphragm that is difficult for deforming.Consequently, as the platinum alloy or the platinum of construction surface, when some distortion took place in construction, desciccator diaphragm can not followed this distortion, causes peel off dangerous higher.In addition, be during hard desciccator diaphragm more than burning till 1mm, contraction to have taken place to burn till as second reason.If the lower film of density also can suppress to burn till contraction, if prevent the evaporable film of platinum, the film that then must have higher density.The density of film can be judged by measuring porosity.If porosity more than 10%, then is difficult to suppress the platinum volatilization, preferably need be below 5%.Increase if improve density then burn till to shrink, increase if the danger of the be full of cracks of film etc. more than 1mm, takes place when then burning till thickness.Thereby, the gauge of overlay film as the thickness of layer integral body preferably below 1mm, more preferably below 800 μ m, further preferably below 600 μ m, most preferably below 400 μ m.
Even can utilize the continuous glass fibre manufacturing that the present invention relates to is the continuous glass fibre of known such glass material with the continuous glass fibre of bushing manufacturing, it also can be made.For example, can adopt E glass (non-alkali glass composition), AR glass (alkali resistant glass composition), C glass (containing acid proof soda-lime glass forms), D glass (realizing the composition of low-k), S glass (realizing the composition of high strength, snappiness rate), T glass (realizing the composition of high strength, snappiness rate) and H glass (realizing the composition of high-k) or M glass, the such glass material of L glass, other material also has no relations in addition.
On the other hand, the continuous glass fibre manufacturing of the present invention manufacture method of bushing has: the bushing main body forms operation, and its assembling comprises the bushing main body of bushing surrounding wall portion, bushing plate and a plurality of nozzles; Apply operation, it forms overlay film at the outside surface of the bushing plate of the bushing main body of having assembled at least; Firing process, it forms dense construction with formed overlay film heating, and this manufacture method is to make the manufacture method of above-mentioned each described continuous glass fibre manufacturing with bushing.
Form operation for the bushing main body, in order to form the essential structure of above-mentioned continuous glass fibre manufacturing with bushing, as long as be assembled with bushing surrounding wall portion, bushing plate and a plurality of nozzle, for assembling sequence, be preferably set to and make high-quality structure with optimum efficiency.For example, both can be preferentially the bushing plate to be set up whole nozzles, opposite with it, also can be to set up nozzle at last.As the method for setting up of nozzle, also can adopt known various method.
In addition, for at least (promptly at the bushing plate of the bushing main body of having assembled, only be bushing plate or bushing plate and bushing surrounding wall portion) outside surface form the coating operation of overlay film, as long as can utilize above-mentioned various methods, the bushing that constitutes stabilised quality gets final product.
For for the firing process that formed overlay film is added the thermosetting dense construction, the state that has abundant weather resistance in order under the temperature of utilizing the continuous glass fibre manufacturing with bushing extraction glass fibre, overlay film to be in, by the temperature that overlay film heating is drawn out of until glass fibre, thereby can form the state of overlay film and the surperficial firm engagement of bushing.
The heating unit that in firing process, carries out, both can be to use partial heating arrangements, it also can be the mechanism that has adopted the whole heating of bushing, in addition, it also can be the mechanism that in electric furnace, various fuel-based process furnace, keeps proper temperature, also have, also the continuous glass fibre manufacturing can be provided in after the glass melting furnace with bushing, utilize the heating source of glass melting furnace to heat.
For the Heating temperature in the firing process, it is preferably at 1100 ℃～1500 ℃ scope internal heating.This is because when bushing use in heating continuous glass fibre manufacturing under than 1100 ℃ of low temperature, exists the globality heating to be in inhomogeneous state, and perhaps generation does not have the danger of the such problem in the position of even heating, so it is not preferred.In addition, opposite with it, if heating above under 1500 ℃ the temperature, then overlay film is endowed and forms overladen heat energy, consequently, sometimes can shorten the life expectancy of overlay film, so also not preferred.According to above-mentioned viewpoint, in order to obtain the more overlay film of stabilised quality, the scope that the Heating temperature in the firing process is more preferably 1200 ℃～1400 ℃.
In addition, the continuous glass fibre manufacturing installation that the present invention relates to is characterized in that, constitutes: use above-mentioned any continuous glass fibre manufacturing bushing, to carry out the spinning of continuous glass fibre.
