Abstract
The present invention belongs to the field of screening equipment technology. In the concrete, said invention provides a preparation method of electroformed screen with stable meshes, storing wear resistance and high accuracy. Said preparation method includes the following main steps: acid-washing the screen mould with wire groove, soaking the cleaned screen mould into a liquor prepared by using tin dichloride and deionized water to make sensitization, then placing the sensitized mould into a light-red liquor made up by adding ammonia water into a solution prepared by using silver nitrate, sodium potassium tartrate and deionized water to coat silver, then removing silver layer outside of silver-coated mould wire groove, copper-plating, nickel-plating copper screen, dehydrating and drying so as to obtain the invented electroformed screen.
Description
Technical field
The invention belongs to the screening plant technical field, specifically relate to a kind of preparation method of electroforming net.
Background content
Electroforming net is used to manufacture accurate electrical forming sieve, be mainly used in the detection of granule materials sreen analysis, survey, the screening of industry granule materials such as metallurgy, abrasive material, pharmacopeia, chemical industry, building materials detects and the accurate screening of research institute of universities and colleges sreen analysis detects with being widely used in.Present screen material is divided into woven wire cloth and perforated metal panel, and perforated metal panel test screen cloth material is a red copper, and adopts electro-chemical machining to form.The woven wire cloth size has yielding, unsettled shortcoming.Though the perforated metal panel screen cloth is not yielding, its weak point is that tolerance range is not high.
Summary of the invention
The objective of the invention is to propose the preparation method of the electroforming net that a kind of mesh is stable, wear resistance is strong, tolerance range is high.
The present invention for the technical scheme that the technical solution problem adopts is: will have the mesh mould of wire casing to use acid soak 10-30 minute, taking out water flushing back immerses by sensitization in the liquid of tindichloride and ionized water preparation, the mould that sensitization is handled is placed on by Silver Nitrate then, the solution of Seignette salt and ionized water preparation also adds ammoniacal liquor and becomes in the pink liquid and be coated with silver, the outer silver layer of mould wire casing that will be coated with silver is again wiped, copper facing in the immersion plating liquid, take out copper-plated mould with the ionized water flushing demoulding after with nickel plating in the copper mesh immersion plating liquid, take out the nickel plating net and wash with ionized water, dewatered drying gets electroforming net.
The liquid of tindichloride of the present invention and ionized water preparation, configuration proportion is tindichloride 8-10 gram: 1000 milliliters of ionized waters.
Solution by Silver Nitrate, Seignette salt and ionized water preparation of the present invention is to be restrained by Silver Nitrate 30-50: the solution of 1000 milliliters of preparations of ionized water restrains with Seignette salt 20-50: the liquid of the solution of 1000 milliliters of preparations of ionized water to obtain after mixing than 1: 1.
The invention has the beneficial effects as follows: the prepared screen cloth of the present invention compared to existing technology, because it is the moulding process of screen cloth becomes one the net grid, stable than the metal wire knitted mesh type, not yielding, than the precision height of perforated metal panel screen cloth, each mesh size positive and negative deviation is less than 1-2 μ m.Owing on screen cloth, plated nickel, therefore strengthened the wear resistance of screen cloth again.In use, can not only improve the quality of Abrasive Industry product, its stronger wear resistance makes screen cloth longer duration of service than the screen cloth of prior art, can also reduce its production cost.
Below in conjunction with embodiment the present invention is described in further details.
