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
The invention belongs to special nickel foam field, be specifically related to the processing technique of a kind of superelevation surface density nickel foam.
Background technology
In oil recovery business, oil extraction pump pump head needs the drainage screen of high-strength corrosion-resisting good filtration effect, at present major part
Using stainless (steel) wire material to make, the drainage screen intensity that steel mesh makes is relatively low, and filter effect is poor, uses high areal density nickel foam
Wire netting can effectively improve intensity and filter effect.But the common electroplating processing method of high areal density nickel foam there will be plating
The subject matter that layer skewness, product stress are relatively big, deformation of products amount is bigger etc., We conducted respectively for problem above
Plant test and finally determine work flow and method.
Summary of the invention
It is an object of the invention to provide the processing technique of a kind of superelevation surface density nickel foam, solve the deficiency of the problems referred to above,
Can be produced with highdensity nickel foam meets the market demand by this technique.
The present invention is achieved in the following ways the processing technique of a kind of superelevation surface density nickel foam, its technological process
Specifically comprise the following steps that
A: foam gluing or chemical plating or PVD are carried out conductive treatment；
B: the foam after conductionization is under the state that there is some tension on four limits and is arranged on resin edge, prevent the groove that is heated
Liquid impulsive force and deform, and in the surrounding of foam, stealing bar is installed and carries out edge current and share, ensure foam with this
The uniformity of nickel layer thickness distribution；
C: carrying out electroplating for the first time, cathode-current density now controls at 3-4ASD/dm, and surface density needs to control at 5000-
7000g/m, prevents intensity deficiency and stress problems of too；
D: for the first time after plating, cleans the residual of the tank liquor after plating and dries；
E: the foam after plating for the first time is carried out hot-pressing processing, it is therefore an objective to the stress of nickel dam after release plating, for secondary nickel plating
Prepare；
F: second time plating uses 2-3ASD/dm electric current density to be machined to target areal density 1.1 times, offsets postorder deformation with this
The surface density caused reduces problem；
G: after second time plating, cleans tank liquor and remains and dry foam；
H: the foam of second time plating is carried out heat treatment, eliminates product stress, the foam defoamed in nickel, reduction surface nickel
Layer；
Described hot-pressing processing, hot compression parameters is pressure 2MPa/600 DEG C/1 hour.
Described heat treatment, parameter: speed 30m/h, oxidation panel temperature 600 DEG C, reduction section temperature 900 DEG C.
The processing technique that beneficial effects of the present invention is invented for this is simple to operate, and production technology is with low cost, and solves
Occurring, owing to density is too high, the phenomenon that plating is uneven in plating, stress is excessive, it is bad to deform the product caused such as excessive
Problem, the use problem brought for plating inequality is solved the most in this process, and the utilization rate of product is greatly improved.
Detailed description of the invention
A kind of processing technique of superelevation surface density nickel foam, a, by foam conductive treatment, then carry out electroplating front preparation,
B, make conduction after foam be under the state that there is some tension on four limits and electroplate, prevent from being heated and sent out by tank liquor impulsive force
Change shape, and to carry out electric current in product surrounding and share, ensure the uniformity of nickel foam layer thickness profile with this, c, plating
Time surface density need to control at 5000-7000g/m, prevent that intensity is not enough and stress problems of too, d, for the first time plating
After, clean the residual of the tank liquor after plating and dry, after e, plating, carrying out hot-pressing processing, it is therefore an objective to after release plating, nickel dam should
Power, prepares for secondary nickel plating, and f, second time plating use 2-3ASD/dm electric current density to be machined to the 1.1 of target areal density
Times, offset, with this, the surface density reduction problem that postorder deformation causes, after g, second time plating, clean tank liquor and remain and dry bubble
Cotton, h, the foam finally carrying out heat treatment elimination product stress, defoaming in nickel, reduction surface nickel dam.
Material-uploading style in described step b is that four limits are tensioned, is had the stealing bar of share current by plating material surrounding.
Stress Release after being electroplated by hot pressing in step e, hot compression parameters is pressure 2MPa/600 DEG C/1 hour.
Described step h carries out heat treatment, heat treatment parameter: speed 30m/h, oxidation panel temperature 600 DEG C, reduction section temperature
900℃。
