The specific embodiment
In the following explanation of the concaveconvex structure of cleaning foil of the present invention (sheet), described is interpreted as sometimes by forming as the sheet (after this being called " substrate ") of bottom and the bossing that forms on it.But this is a kind of references for the shape and size of explaining bossing various piece on every side simply, does not limit its forming process.The shape of sheet can be interpreted as comprising the lip-deep female shapes of original sheet, and remainder is protruding relatively part.In the present invention, term " sheet " is the notion that comprises " film ".
Fig. 1 schematically represents described cross-section structure.There is no particular limitation to the material etc. that constitutes described, and to have a male and fomale(M﹠F) just passable as long as the contact-making surface of the cleaning objects that will rub can be processed into, and select to use organic material and inorganic material suitably according to the kind of cleaning objects.
Described contact-making surface (in the scheme shown in the figure, the upper surface of sheet) with the cleaning objects that will rub, contact-making surface is in two surfaces at least, contact-making surface is the male and fomale(M﹠F) that comprises bossing 1 and sunk part 2.
Although mostly just contact-making surface is made on sheet surface, according to purposes, two surface can all be a contact-making surface.
In described preferred use, as shown in Figure 2, when using crooked widely described of cylinder R, with the surface of crest portion friction cleaning objects (for example plates for screen printing etc.).Like this, the material that constitutes described is preferably given suitable flexibility and mechanical strength to sheet.From this respect, the material that constitutes described is preferably polymeric material.In addition, the aforementioned polymer material is preferably given the suitable rigidity of not damaging cleaning objects such as plates for screen printing for example to sheet and is given when bearing the sheet distortion when contact bossing to the suitable elasticity of the seamless adhesion on plate surface.
Except the above-mentioned bonding sheet of JP-A-2000-177110 and JP-A-2001-348541, also know the sheet of the compounds (JP-A-11-224414 etc.) of porous layer lamination on adhesive layer such as for example net as the stain on clean article surface.
On the other hand, the present invention uses bossing to be integrally formed in the scheme of on-chip simple concavo-convex substrate.When cleaning objects was plates for screen printing, the printing paste that is accumulated on the plates for screen printing back side was to remove target.
When the S1 of the plate surface of the sheet friction plates for screen printing S with this formation, as shown in Figure 2, can only swipe and remove back side paste 201 with bossing 1.The paste that bossing 1 obtains is collected in the sunk part 2 (for example 202).
In other words, the dorsal part of silk screen plate because cleaning foil is physically swiped is so no matter solvent types how in the paste, can clean.
There is no particular limitation to polymeric material, so long as that they are various plastics is just passable, for example can mention polyethylene, polypropylene, polyvinyl chloride, polyamide, polyurethane, glassine paper etc., they can use individually or with the mixture of two or more in them.Consider the processability of productivity ratio, cost, male and fomale(M﹠F) etc., in these, for example various vistanexes such as polyethylene are particularly preferred materials.As vistanex, can mention polyvinyl resin (for example high density polyethylene (HDPE), medium density polyethylene, low density polyethylene (LDPE), LLDPE, ultra-low density polyethylene, ethylene-vinyl acetate copolymer, ethene-ethyl acrylate copolymer, ethene-propylene copolymer etc.), acrylic resin (for example polypropylene etc.), thermoplastic elastomer (TPE) etc.These resins can contain known additives, for example pigment, filler, antioxidant, lubricant etc.
Described formation can be any in multilayer (lamination) structure made of the single layer structure integrally made by homogenous material and different material layer.
There is no particular limitation to the target of removing with described, can mention the wet semisolid that contains solvent, for example various cream, ink, glue, adhesive, coating etc.Removing target is not to contain solvent, comprises not solvent-laden wet semisolid material.As discussed in the background art, because high definition, there are some problems in the serigraphy that is used to form the fluorescent material layer of PDP.Like this, be that it is remarkable especially that the serviceability of sheet becomes when being used to form the fluorescent material cream of fluorescence coating of PDP when removing target.
When removing target and contain solvent, solvent for example can be aliphatic hydrocarbon, for example hexane, heptane, Mineral spirits etc.; Alicyclic, for example cyclohexane etc.; Aromatic hydrocarbon, for example toluene, dimethylbenzene, solvent naphthalene, tetralin, dipentene etc.; Alcohols, for example methyl alcohol, ethanol, isopropyl alcohol, butanols, isobutanol, sec-butyl alcohol, cyclohexanol, 2 methyl cyclohexanol, tridecanol etc.; Ester class, for example methyl acetate, ethyl acetate, isopropyl acetate, butyl acetate etc.; Ketone, for example acetone, MEK, methyl iso-butyl ketone (MIBK), cyclohexanone, methyl cyclohexanone, diacetone alcohol, isophorone etc.; Dihydroxylic alcohols, for example ethylene glycol, propane diols, diethylene glycol, triethylene glycol, DPG etc.; Glycol ether, for example butyl cellulose, propylene glycol monomethyl ether, dihydroxypropane single-ether, propylene glycol monobutyl ether, diethylene glycol monobutyl ether etc.; Diatomic alcohol ether acid ester, for example butyl cellulose acetic acid esters, propylene glycol methyl ether acetate, propylene glycol monoethyl ether acetate, butyl carbitol acetate etc.; Water etc.
When the removal target is screen printed inks, use solvent with middle boiling point (boiling point: about 120～230 ℃) and solvent mostly with higher boiling (boiling point: about 230～320 ℃).
And, the solvent that contains as the fluorescent material cream of PDP, for example can mention the have higher boiling solvent of (boiling point: about 230～320 ℃), for example butyl carbitol acetate, diethylene glycol monobutyl ether, butyl carbitol acetate/diethylene glycol monobutyl ether (9/1 (weight ratio)) etc.
Do not limit the relief pattern of male and fomale(M﹠F) especially, for example can mention on flat substrate, at random or regularly being furnished with relief pattern independent appearance, crestal line shape bossing, on the interarea of plain film, at random or regularly arrange the independent non-relief pattern that penetrates bossing of crestal line shape that occurs etc. with the whole thickness of sheet.
They are variation bodies of relief pattern, and the relief pattern that looks like the sunk part of independent appearance can be interpreted as the pattern that crestal line shape bossing is crossed as mesh shape.On the contrary, the relief pattern that looks like the bossing of independent appearance can be interpreted as wherein the channel form sunk part and intersects webbed pattern.No matter any relief pattern is explained for convenience, all uses bossing on the upper surface that is formed on substrate to explain the shape and size of every part.
The scheme optimization of bossing is rectangular crestal line shape (mountain range) thrust with constant altitude, rather than the thrust of the independent appearance of point sample, thereby crestal line shape bossing can serve as scraping blade, and target is removed in scraping, leaves no trace.
Therefore, when bossing during as crestal line, the direction of advance during described friction cleaning objects surface should with the longitudinal direction shape of the crestal line of bossing at an angle.
On the contrary, when described direction that has strips as shown in Figure 3 and determine to use according to the profile of sheet, the longitudinal direction of crestal line shape bossing is the direction that forms the right angle with the service orientation (longitudinal direction of band in Fig. 3) of sheet, shown in Fig. 3 (a), or form the direction at θ 1 jiao (1＜180 ° of 0 °＜θ) rather than right angle, shown in 3 (b).
The scheme that forms 1 jiao of θ rather than right angle is preferred, even this is because sunk part has bigger width, the bottom of sunk part also is not easy to touch cleaning objects when cleaning, owing to contact with the bottom of sunk part, has reduced removability like this.
In this case, the θ that is limited to acute angle is desirably 1≤90 ° of 30 °≤θ for 1 jiao, and particularly 45 °≤θ is 1≤90 °.
When bossing during as crestal line, the pattern that depression on the male and fomale(M﹠F) and projection are described for example is, shown in Fig. 3 (a), 3 (b), Fig. 4 (a), 4 (b), crestal line shape bossing 1 compartment of terrain is arranged in the bar grain pattern relief pattern on the first type surface of substrate; Shown in Fig. 4 (c)-(e), crestal line shape bossing is arranged in the net form relief pattern on the first type surface of substrate with net form; Shown in Fig. 5 (a)-(f), dotted line, arbitrary curve and the broken line that matches with the opening of cleaning objects disperses regularly or brokenly or is arranged in relief pattern on the first type surface of substrate etc.Thick line among these figure is only represented the pattern that mark on the summit of bossing, the width of thick line not corresponding the width w1 of long rectangular wave sample bossing shown in Figure 1.
In the candy strip of Fig. 4 (a), although the crestal line of bossing 1 is a waveform, it can be an arbitrary curve.In the candy strip of Fig. 4 (b), the straight line crestal line of bossing 1 is a broken line.In this case, can determine the direction of advance (right side of figure or left to) of sheet suitably according to the accumulation of removing target etc.
In the net form pattern of Fig. 4 (c), the crestal line of bossing forms grid hole (lattice mesh).Angle theta 2, the θ 3 of the crestal line of two intersections can be identical or different.Fig. 4 (d), (e) represent the example of other net form pattern, and wherein Fig. 4 (d) is the broken line pattern, and Fig. 4 (e) is that triangle is made the minimum mesh pattern that constitutes the unit.
In the scheme of Fig. 5 (a), (d), crestal line shape bossing 1 is depicted the ring of independent appearance, in the scheme of Fig. 5 (b), (e), crestal line shape bossing 1 is depicted the short broken line of independent appearance, in the scheme of Fig. 5 (c), (f), crestal line shape bossing 1 is depicted the short lines of independent appearance.In these all schemes, separately the bossing that occurs regularly (Fig. 5 (a)-(c)) or at random (Fig. 5 (d)-(f)) be arranged on the first type surface of substrate.In these all schemes, the shape of the independent appearance that crestal line shape bossing 1 is drawn dimensionally can be identical or different, big and little can arranging regularly or be dispersed in the mixture fully brokenly.
In all above-mentioned patterns, the part except that bossing 1 is relative sunk part 2.As the represented pattern of the crestal line of bossing can be the pattern of the groove of sunk part.
In every kind of pattern, the crestal line direction shape of the service orientation of definite sheet and bossing at an angle suitably.In addition, the pattern of enumerating only is the example of relief pattern, can be according to the surface condition of cleaning objects, remove target etc. and form any relief pattern.
When bossing during as crestal line, the shape of bossing, the effect of blade and cramping mode etc. when particularly influence bossing and contact with cleaning objects perpendicular to the cross sectional shape (after this being called for short " shape of cross section ") of the bossing of the longitudinal direction of crestal line cutting influence the removeability of removal target conversely again widely.
Can determine the shape of cross section of bossing according to the mechanical performance of the viscosity of removing target and the material that constitutes sheet suitably.For example, the semicircle shown in the various zigzag waves shown in long rectangular wave shown in Figure 1 (comprise Fig. 6's (a) trapezoidal), Fig. 6 (b)-(e), triangular wave, Fig. 7 (a), the semiellipse shown in Fig. 7 (b) etc. all are preferably shape of cross section.
Sheet with long rectangular wave shown in Figure 1 can advance along the direction of any side, and this is because limit 1a, the 1b of the convex shoulder of bossing are identical.Because the width w1 of bossing is almost identical with distance from the summit to the foundation, so bossing has quite high toughness, provides strong seldom crooked scraping blade.
By contrast, the triangular wave shown in Fig. 6 (b) has the directionality of use, when it when the dextrad of figure is advanced, described can be more effectively reacts on the removal object with the edge one at the top of bossing.And, to compare with long rectangular wave, the most advanced and sophisticated bending easily of bossing impels the spill and the bossing that meet on the plate face.And, be favourable as the bossing of triangular wave, this is because for the inclined-plane, the volume of sunk part increases.
The shape of cross section of Fig. 6 (a) is a kind of long rectangular wave, has the long rectangular wave characteristic of Fig. 1 and the triangular wave characteristic of Fig. 6 (b) in combination.
The arrangement of bossing needs not to be equably at interval, and for example, shown in Fig. 6 (c), can be intensive or sparse at interval.
Shown in Fig. 3 (b), parallel with the direction of advance of crestal line when bossing and direction of advance shape at an angle but when being not the right angle when the shape of cross section of bossing, rather than during perpendicular to longitudinal direction, can explain easily.
Crestal line shape bossing with long rectangular wave part shown in Figure 1 preferably has the width w1 of about 10～2000 μ m.According to the height h2 of bossing, the width w1 littler than this scope produces distortion such as for example bending, is difficult to as scraping blade.On the other hand because the upper surface of long rectangular wave bossing to remove target remove or safeguard inoperative, so the width of bossing wideer than aforementioned range be useless.
When estimating according to the following method of embodiment 1, the more preferably scope of the width w1 of bossing is 50～2000 μ m, and for the removal of the fluorescent material cream of PDP, 100～1000 μ m are effective especially.
On the other hand, evaluation method according to following embodiment 2, wherein use plates for screen printing to make cleaning objects, at length reproduce the mode of using sheet, the more preferably scope of the width w1 of bossing is 15～1000 μ m, and for the removal of the fluorescent material cream of PDP, 20～500 μ m are effective especially, in evaluation test, 25～50 μ m are be evaluated as good especially.
Although the more preferably scope of the width w1 of the bossing of embodiment 1 and the more preferably scope of initiate embodiment 2 are slightly different,, it is to be caused with different evaluation methods by the different objects that will clean.Comprise the several preferable range that obtain by multiple evaluation although it is considered herein that the gamut of preferred 10～2000 μ m,, it can not have problems.Identical content is applicable to the ratio of height and the whole thickness of sheet of height, bossing of bossing and the width of the sunk part mentioned later.These scopes all are preferred versions of the present invention.But, because the embodiment 2 that mentions below reproduces and the condition of the concrete applications similar of reality, so the reliability height of itself estimating.
Because as the degree of depth of sunk part, the height of bossing (h2 of Fig. 1) not only influences the deformation extent of bossing, and the volume of influence removal target, so consider the load capacity of sheet when using, preferentially determine this height.
Although the preferred heights of bossing changes with the bossing of shape of cross section,, when shape of cross section was long rectangular wave, it was preferably about 10～1000 μ m.From aforementioned range, when estimating according to the evaluation method of following embodiment 1, the height of bossing is 20～800 μ m more preferably, and for the fluorescent material cream of removing PDP, 30～500 μ m are effective especially, not waste.When estimating according to the evaluation method of following embodiment 2, the height of bossing is 10～800 μ m more preferably, and for the fluorescent material cream of removing PDP, 13～500 μ m are effective especially, not waste.Particularly, find that through test evaluation 15-30 μ m is especially good.
Although the preferred ratio of the whole thickness of the height of bossing and sheet (height of the thickness+bossing of substrate) changes with the shape of cross section of bossing, but, by evaluation method evaluation according to following embodiment 1, this is than being 10%～90%, preferred 20%～85%, for the fluorescent material cream of removing PDP, 30%～80%, effective especially, not waste.By the evaluation method evaluation according to following embodiment 2, this is than more preferably 10%～85%, for the fluorescent material cream of removing PDP, and 13%～80%, effective especially, not waste.Especially, 15%～30%, the good result of test evaluation.
The width of sunk part (w2 of Fig. 1) influences the collected volume of removing target with the aforementioned height h2 of bossing.
The preferable width of sunk part changes with the shape of cross section of sunk part.When the shape of cross section of sunk part is long rectangular wave, the evaluation of the evaluation method of the following embodiment 1 of foundation, about 100～3000 μ m are preferable range.The evaluation of the evaluation method of the following embodiment 2 of foundation, about 10～3000 μ m are preferable range.
Although change with the height (degree of depth of sunk part) of bossing,, when the width of sunk part during less than above-mentioned scope, the space of preserving the removal target that scrapes off becomes littler than the actual volume of removing target, can not remove object fully.On the other hand, when the width of sunk part during than above-mentioned wide ranges, it is too thin that the density of bossing becomes, and the removability of removing target reduces.
The evaluation of the evaluation method of the following embodiment 1 of foundation, the more preferably scope of the width w2 of sunk part is 200～3000 μ m, for the fluorescent material cream of removing PDP, 300～2000 μ m are effective especially.The evaluation of the evaluation method of the following embodiment 2 of foundation, the more preferably scope of the width w2 of sunk part is 15～3000 μ m, for the fluorescent material cream of removing PDP, 20～2000 μ m are effective especially.Especially, 50～150 μ m are good results of test evaluation.
When semicircle shown in the trapezoidal wave shown in the shape of cross section image pattern 6 (a)-(c) of bossing or sawtooth waveforms or image pattern 7 (a) and (b) or semiellipse, the full duration w1 of bossing is the width of its foundation.The width w2 of sunk part is the size of remainder.
When distance between the position of bossing is unequal, can explain the overall with w1 of bossing suitably according to the intention of design.For example, when the single bossing of continuous two bossings 11,12 zigzag upper surface shown in (c) that is designed to have Fig. 6, the full duration w1 of bossing is the combination of two width of bossing 11,12.
When the bottom at sunk part of shape of cross section picture shown in Fig. 6 (d) of bossing do not have the triangular wave of the area of plane, the full duration w1 of bossing is the width (promptly from the bottom of a paddy to the width of the bottom of next paddy) of foundation, the width w2 of sunk part be from the top of a bossing to the width at the top of next bossing, as shown in the drawing.
As long as when the bottom of the shape of cross section picture of bossing such as Fig. 6 (e) sunk part that is shown in does not have the triangular wave of the area of plane, the full duration w1 of bossing is the width from the bottom centre of sunk part to the bottom centre of next sunk part, the width w2 of sunk part be from the top of a bossing to the width at the top of next bossing, as shown in the drawing.
Other scheme of the shape of cross section of Fig. 8 and 9 expression bossings.
In the scheme of Fig. 8 (a)-(f), the shape of cross section of bossing has the multi-ladder shape, and wherein the foundation 13 of bossing has the less crestal line shape projection 14 that forms thereon.Shape of cross section as every part, the long rectangular wave of foundation 13 image patterns 8 (a)-(c) of bossing, the semiellipse of foundation 13 image patterns 8 (d)-(f) of bossing, semicircle among crestal line shape projection 14 image patterns 8 (a), (d), the triangle of crestal line shape projection 14 image patterns 8 (b), (e), the square of crestal line shape projection 14 image patterns 8 (c), (d).
In the scheme of Fig. 9, the shape of cross section of bossing is as long rectangular wave, and wherein the height of each bossing (degree of depth of sunk part) is different mutually.The Pareto diagram of the sunk part that each is different can be the sunk part with various degree of depth that the cycle of particular types repeats or arrange arbitrarily.And the width of bossing and the width of sunk part can be uniform or uneven, can design feasible surface state according to cleaning objects, removal target etc. suitably and show preferred removeability.
Figure 10 is the perspective view of other scheme of expression relief pattern.In the scheme of this figure, make with the direction of advance shape of sheet at an angle of 90 the crestal line shape bossing 16 of the crestal line shape bossing 15 of (can not be 90 ° of angles) and direction of advance intersect the preparation lattice.And in the scheme of this figure, bossing 15 is to scrape off the scraping blade of removing target, and bossing 16 is located lowlyer than bossing 15.As a result, bossing 16 serves as rib and improves sheet rigidity and mechanical strength as a whole, serves as simultaneously to keep partition wall and spill with the removal targets such as for example paste that prevent from the to obtain side from sheet.
