Machining technology of ultrahigh-surface-density foam nickel

Abstract

The invention discloses a machining technology of ultrahigh-surface-density foam nickel, and belongs to the field of special foam nickel. Firstly, foam is subject to conductive treatment, preparing before electroplating is carried out, the foam obtained after conductive treatment is electroplated under the state that the four sides have certain tension, hot pressing treatment is carried out after electroplating, secondary electroplating and heat treatment are carried out, the machining technology is easy to operate, the production technology is low in cost, the problems that due to the fact that the density is too high, uneven electroplating appears in electroplating, the stress is too large and deformation is too large, products are poor are solved, the use problem brought by uneven electroplating also can be solved in the technology, and the use rate of the products is greatly improved.

Description

technical field [0001] The invention belongs to the field of special foamed nickel, and in particular relates to a processing technology of super-high surface density foamed nickel. Background technique [0002] In the oil production industry, the pump head of the oil production pump needs a high-strength, corrosion-resistant filter with good filtering effect. At present, most of them are made of stainless steel mesh. The filter made of steel mesh has low strength and poor filtering effect. High surface density foam is used. Nickel metal mesh can effectively improve the strength and filtering effect. However, the ordinary electroplating processing method of high surface density nickel foam will have major problems such as uneven coating distribution, large product stress, and large product deformation. We have conducted various tests to finally determine the processing flow and method for the above problems. Contents of the invention [0003] The purpose of the present in...
