The thickness of the crossing points (36) is not equal to the thickness of the dykes (34). The metal screen material (32) or a combination thereof with a perforating screen (17) can be used as a perforating stencil for the perforation of film material (2), for example made from plastic material.
Description
According to first aspect, the present invention relates to a kind of screen material that is made of metal with flat side, comprise that described dyke limits the boundary of eyelet by crosspoint dyke connected to one another (dyke) network.More specifically, according to the screen material that the present invention relates to electrotyping forming of this aspect, preferred seamless cylindrical screen material.
Such screen material is known in professional domain and is used to many purposes, for example serigraphy, plastic foil perforation etc.Method for punching and device are known for example from US-A6 in 024,553.
In this known method that is used for making the plastic foil of perforation, thin plastic is directed on perforated cylinder, and described cylinder also is called as perforated template, and described film is exposed to pressure fluid by the part, for example water or air.The result is, described film is locally deformed into the perforation of described perforated cylinder and is pressed into them until film rupture, forms perforation in the film so that be in these positions.
The perforated template of using in this known method comprises moulding cylinder with external styling surface and inner fastening surface and the supporting cylinder that carries described moulding cylinder.Such supporting structure is normally needed so that prolong the service life of described template, is subjected to pressure fluid described service life, water for example, adverse effect.The tap that is used to make described fluid to discharge extends through the wall portion of moulding cylinder.If the supporting cylinder has covered some tap, then there is in the film risk that does not form perforation in these positions or formed not enough perforation.And, the adverse effect of the fluid that the shape of the perforation that is formed can be splash or flow back to.For fear of these risks, according to top patent, suggestion adds the structure of fluid penetrable between described moulding cylinder and supporting cylinder, for example metallic sieve or mesh (mesh), the lateral dimension (width) of the dyke of the structure of described fluid penetrable or wire (wires) is less than the maximum gauge that is substantially circle or oval tap.Therefore all described taps are opened at least in part, and have avoided (part) of tap to block.Described fluid can be successfully drained away and be discharged.
Generally, explicable is that perforated template must have enough intensity on the one hand and must guarantee the good discharging performance of fluid on the other hand.
Yet because the eyelet in different layers is alignd, therefore according to top United States Patent (USP), it is complicated making the perforated template with layer structure.This is that unjustified eyelet can cause being called as the generation of a mole effect (Moire effect) because owing to there is the regular decorative pattern of eyelet, described eyelet is overlapped each other.This Moire effect can cause not boring a hole or the number of holes deficiency in plastic foil.
Because the complexity of known perforated template above-mentioned, need have enough intensity on the one hand and the optional embodiment of good perforation quality is provided on the other hand.One of purpose of the present invention is to address that need.
In addition, the present invention is based on provides a kind of screen material, especially for the screen material of the perforation of plastic foil, makes the risk that Moire effect takes place in described material be lowered, purpose.
For this purpose, the invention provides a kind of metal screen material with flat side, comprise that described dyke defines the boundary of eyelet by crosspoint dyke network connected to one another, the thickness in described crosspoint and the thickness of dyke are unequal.
An important technology aspect according to screen material of the present invention is: the described screen material with flat side does not have uniform thickness (highly), but the crosspoint of independent dyke, i.e. tie point, thickness different with the thickness of described dyke itself.When screen material according to the present invention was used as supporting structure in the perforated template, this provided a large amount of supporting-points for perforated screens or moulding cylinder on the one hand.On the other hand, this structure has guaranteed that perforated template has good penetration, and this is because have enough permeability in the plane of the supporting structure between dyke and the crosspoint.The height in the crosspoint different with respect to dyke only appears at according on the side in the screen material of the present invention, particularly appears on the side relative with flat side.In this manual, term " screen material " is understood to mean that thin material, and the first type surface of described thin material is known as the side, so that they and thin lateral edges are made a distinction.Term " flat " means the plane that does not have ledge.Described screen material can for example exist with flat type, but preferably seamless cylinder.
It should be noted that from being known in essence, and in this material, if desired, the coat of the line of described weaving structure by using electrotyping forming is by connected to each other based on the screen material of weaving structure.Yet such screen material does not have any flat side, and this is because the line of described weaving structure is alternately intersected with each other on each side.As the result that these lines intersect, such screen material at the thickness of the position in these crosspoints greater than the thickness of line independently.Especially at US-A 1,934,643, US-A 5,939,172 based on the example of such screen material of weaving structure, and US-A 5,453,173, and US-A 3,759,799, and US-A 4,609,518 and file US-A above-mentioned 6,024,553 in be described.
In the present invention, screen material is advantageously made by monolithic, as from following to the description of making the employed method of described material with understandable.
According to the preferred embodiment of screen material of the present invention, the thickness in crosspoint is greater than the thickness of dyke, as what will be explained in more detail below.The difference of crosspoint thickness and dyke thickness is preferably in the scope of 20-250 micron, more preferably in the scope of 100-200 micron.
For the surface that contacts with top perforated screens, the drift angle in the crosspoint of rising is preferably less than 120 °, is to be 100 ° under 130 microns the situation in difference in height for example.
Screen material is tubulose advantageously, and more specifically described screen material exists with the form of seamless cylinder, so that whole peripheral surface can be provided with screened port, described eyelet optionally is regular pattern.Described screen material, the particularly screen material that exists with cylindrical form preferably obtain with electrolysis mode, will illustrate as following.
Preferably electroformed screen material according to the invention, described screen material is as the support screen in support screen and the perforated screens assembly, and described assembly is suitable for use in the perforation of film, advantageously has one or more following character:
The mesh number of 30-80 mesh.By the mode of example, described eyelet is arranged to hexagon, quadrature or Else Rule pattern.Mesh number less than 30 situation under, there be the supporting degree inadequate risk of support screen to perforated screens, and under fineness surpasses the situation of 80 meshes, have be used to by water be injected in form perforation in the film fresh water (FW) not by the abundant risk of venting.
For intensity, the integral thickness of screen material (part that comprises rising) is advantageously greater than 600 microns (being generally the 900-1000 micron).(the open rate of optics (optical openess) advantageously surpasses 25% (being generally 40%-50%) to the permeability of described screen material.
Be used for being preferably nickel according to the metal of screen material of the present invention.
According to second aspect, the present invention relates to a kind of metal screen material that is used to produce with flat side, described screen material comprises the boundary that defines eyelet by crosspoint dyke network connected to one another and described dyke, particularly according to screen material of the present invention, method.Method according to the present invention comprises at least one or a plurality of being used under controlled condition at electroplating bath so that in the speed of growth in crosspoint described at least one growth step and the unequal mode of the speed of growth of described dyke, the growth step that screen skeleton with flat side is thickened by electrolysis mode, thus make that the thickness of the thickness in described screen material crosspoint and dyke is unequal.
In this method according to the present invention, employed parent material is the screen skeleton with two flat sides.Such skeleton is the very thin screen material that has limited the primarily two-dimensional shape of described network.Such skeleton can the manner known per se, preferably by electrotyping forming on conductive die, obtained, described conductive die is provided with the island portion of independently insulating, described insulation island portion is for example made by photoresist, and described insulation island portion is corresponding to the screened port that will be formed.Dyke is corresponding to not being insulated die tracks (dietrack) or the part that material covers.According to the present invention, described skeleton experiences one or more growth steps under controlled process conditions.Generally, the elemental height difference between dyke and the crosspoint is produced in first step, and described difference in height is enhanced in step subsequently subsequently.
In other words, described screen material is advantageously produced under the help of multistage electroforming process.This technology comprises:
Stage 1: at mould, preferably on cylindrical mold, deposition has the metallic sieve skeleton of flat side, and described screen skeleton is for example made by nickel.
Stage 2: this stage comprises one or more step or growth steps of thickening.Select the described condition that thickens step, make to form required dyke shape and cross-point geometry, the difference in height between described dyke and the crosspoint may be a plus or minus, and this depends on what is that required and needs are used in expection.Described growth can take place in both sides, yet under described situation, the different speed of growth relevant with the position in dyke and crosspoint occurs over just on the side.The described step that thickens has the selective growth feature, described selective growth feature displays in electrolytic growth, described electrolytic growth does not preferably take place in hole, and on dyke and crosspoint, take place really, promptly compare, almost do not have widening of dyke or crosspoint with the increment of thickness direction.
Thicken in the step at one, the difference in height of the basic configuration of dyke shape and the final screen material that obtains is defined.In a step or a plurality of step subsequently, but this basic configuration further growth and makes that shape facility is clearer and more definite or strengthens until reaching required final thickness.
Advantageously be subjected to the control of one or more following parameters in the difference in height that provides thickening of basic configuration to form in the step.
Force body lotion stream to pass through screen skeleton.The flow velocity of electrolyte is advantageously at 200-600l/dm

Another factor that influences local growth is to be known as the factor that primary current distributes, and it is relevant with how much distributions of the metal that has existed that described primary current distributes.Suppose that the distance between anode and the negative electrode (skeleton) is identical, narrow shape is bigger than the extent of growth of wide shape.
The invention still further relates to use and be used for the perforation of membrane material according to screen material of the present invention or the screen material that utilizes the method according to this invention to obtain.Screen material according to the present invention is advantageously used for support screen, but also can be used as perforated screens.
In addition, the present invention relates to the assembly of support screen and perforated screens, in described assembly, support screen comprises according to screen material of the present invention or the screen material that utilizes the method according to this invention to obtain.The assembly of this concentric screens also has been known as perforated template.The mesh number of described support screen is also preferred lower than the mesh number of perforated screens.
When having more or less two screen clothes of the eyelet of regular pattern when being placed in that go up on the top each other, Moire effect takes place in result as interfering usually.This effect can be destructive in the product of perforation, and this is because the perforation that is intended to produce will not form or will form by halves.By combination of screens according to the present invention, this phenomenon is supported contact area little between the crosspoint of rising of screen cloth and perforated screens and suppresses.The ratio of the mesh number of two kinds of screen clothes also plays effect.Find that if the ratio between two kinds of repetition rates of two patterns is integer ± 0.5 (1.5,2.5,3.5 etc.), the Moire effect of then described two regular patterns is destructive minimum.
This means that described support screen preferably has in the following mesh number: 66.6 meshes under the situation of the perforated screens of 100 meshes; 40 meshes; 28.6 individual mesh; 22.2 individual mesh etc.For thicker support screen, the degree that this Moire effect is minimized (promptly no longer perceiving) increases.Have been found that described destructive Moire effect has no longer perceived when utilizing when according to the support screen of the perforated screens of 100 meshes of the present invention and 40 meshes plate being bored a hole.
The invention still further relates to the various methods that are used to make the assembly of tubulose perforated screens and tubular support screen cloth.
