[0018] The specific method of electroplating to prepare stainless steel wire mesh is as follows:
[0019] Use the existing weaving technology to weave stainless steel wire mesh, chemically degrease the woven stainless steel wire mesh, wash it with hot and cold water, put it into the plating tank for electroplating nickel, take it out after a certain period of reaction, wash it with water, dry it, and coil it. Can.
[0020] 1. Chemical degreasing: bath composition and working conditions are as follows
[0021]
[0022] 2. Hot and cold water washing: first rinse with hot water (40-50 degrees Celsius) to prevent residual degreasing liquid on the surface of the stainless steel wire mesh, and then rinse with cold water (room temperature).
[0023] 3. Plating solution formula and process conditions:
[0024]
[0025]
[0026] The stainless steel wire mesh of this formula needs to be charged into the tank, first use 3~4A / dm 2 The impulse current is 1~3min, and then drops ...

Abstract
A method for manufacturing an integral wire mesh includes steps: 1 weaving a wire mesh by the aid of existing weaving technology; 2 performing pretreatment; 3 realizing electroplating or chemical plating in a plating tank for a set time period; and 4, washing by the aid of water, drying and coiling. A method for realizing pretreatment includes (1) removing oil and washing by the aid of water by a chemical method or removing oil by a physical method; and (2) pickling or washing by the aid of water as needed after the step (1) is realized. Activation treatment can be carried out before chemical plating. An obtained plating can consist of single metal such as nickel or copper or silver or tin or iron or chromium and the like, or alloy such as nickel-phosphorus alloy or nickel-boron alloy or tin-lead alloy and the like. A chemical plating consists of single metal such as nickel or copper or silver or tin or iron or chromium and the like, or alloy such as nickel-phosphorus alloy or nickel-boron alloy or tin-lead alloy and the like. Warps and wefts of the wire mesh are integrally covered by means of electroplating or chemical plating, stress uniformity and tensile strength are improved, and integral wire meshes with optional transmittance can be prepared.
Description
technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to a method for manufacturing an integral wire mesh, that is, the wire mesh is prepared by electroplating or electroless plating after the mesh is woven by a weaving method. Background technique [0002] At present, the wire mesh is mostly made of warp and weft interweaving. The warp and weft of the woven mesh are only overlapped and not connected as a whole. Deformation, so it is difficult to weave a wire mesh with high transmittance, and when the wire mesh is cut, the edge of the warp or weft is prone to fall off due to the disconnection of the warp and weft, which affects normal use. Contents of the invention [0003] The purpose of the present invention is to provide a method for making integral wire mesh. This method is based on the warp and weft woven wire mesh and is reinforced by electroplating or electroless plating to make an integral wire mesh at the ...
