Abstract
The invention discloses a processing technology of scales on the surface of a stainless steel needle tubing, and belongs to the technology of the metal surface chemical treatment process in the field of medical treatment. The processing technology comprises the following steps: greasy dirt treating of a workpiece surface, casing, phosphatization, flushing, casing pipe removing, ultrasonic cleaning, drying and packaging. Compared with the prior art, the processing technology has the advantages that the surfaces of the manufactured scales are smooth and bright, and the scales are clear and are not easy to fade.
Description
Technical field
The present invention relates to the technology of metallic surface chemical treatment technology in a kind of medical field, specifically, relate to a kind of stainless steel needle tube-surface scale complete processing.
Background technology
At present, stainless steel needle tube-surface scale complete processing generally adopt marking machine to finish the making of scale marks through the method for electrolytic coloring, but the scale marks that this method is made can make the surface not round and smooth, the tarnish that is faint in color, and time one is long fades easily, does not see.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of stainless steel needle tube-surface scale complete processing, can make that the scale marks smooth surface of making is glossy, clear scales, fugitive color not.
For achieving the above object, the present invention is by the following technical solutions:
A kind of stainless steel needle tube-surface scale complete processing is characterized in that: comprise following concrete steps:
A. pending stainless steel tube or stainless steel bar surface degreasing is dirty, clean up;
B. according to the requirement of scale marks spacing dimension, put successively several plastic pipes, plastic pipe tightly is enclosed within on stainless steel tube or the stainless steel bar, and the space between the adjacent plastic pipe is corresponding with the scale marks of stainless steel tube or stainless steel bar;
C. with the plastic pipe sealing of workpiece bottom, vertically insert in the container;
D. in following ratio preparation Phosphating Solution:
Chromium trioxide: 2～4% sulfuric acid: 50～55%
Phosphoric acid: 11～14% water: 27～37%
E. the Phosphating Solution with preparation adds the container that fills workpiece, and liquid level should not surpass upper sleeve portion;
F. heat, the Phosphating Solution temperature is raised to 90 ℃～100 ℃, and is incubated 1～2 hour;
G. take out workpiece, flushing removes sleeve pipe;
H. put into ultrasonic cleaner and clean, oven dry, packing.
Above-mentioned stainless steel needle tube-surface scale complete processing, described Phosphating Solution temperature length to 92 ℃～98 ℃ is incubated 1.2～1.8 hours.
Above-mentioned stainless steel needle tube-surface scale complete processing, described Phosphating Solution proportioning is chromium trioxide: 3%, sulfuric acid: 52%, phosphoric acid: 13%, water: 32%.
Above-mentioned stainless steel needle tube-surface scale complete processing, described temperature is raised to 95 ℃.
Above-mentioned stainless steel needle tube-surface scale complete processing, described temperature insulation 1.5 hours.
The composition of the iron in the stainless material of the present invention generates ferrous ion with sulfuric acid, phosphatase reaction first; Chromium trioxide generates dichromic acid with the water effect under acidic conditions, be a kind of strong oxidizer, then reacts with ferrous ion, changes the chromium ion of trivalent into by the chromium of sexavalence, and trivalent chromic ion and phosphate anion reaction formation Plessy's green are in the surface.Chromium in the stainless material, nickel generate trivalent chromic ion, bivalent nickel ion with sulfuric acid reaction under the condition of heating simultaneously, then form phosphoric acid salt with the phosphate anion reaction.The color of phosphoric acid salt and Plessy's green and stainless steel needle tubing or stainless steel bar have obvious difference, just form smooth glossy, clear scales and are difficult for the scale marks of armpit look.The present invention adopts the method for chemical corrosion to form scale at stainless steel needle tubing or stainless steel bar, compared with prior art, the invention has the advantages that: the scale marks smooth surface of making is glossy, clear scales, fugitive color not.
