Problems solved by technology

With the increasing application of stainless steel products, especially decorative stainless steel products, some traditional single surface treatment methods can no longer fully meet people's increasing aesthetic requirements.
The existing ordinary stainless steel surface is not resistant to friction, and there will be scratches when it is rubbed. It is easily polluted by grease and uric acid contained in fingerprints, and it is not easy to scrub. It will become gray and eclipsed after a long time. The stains formed are not easy to scrub off, and the surface of the stainless steel decorative plate gradually loses its luster, which is very unsightly, thus reducing the grade of the product and the added value of the product is not high

Embodiment Construction

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the examples, which are only used to explain the present invention and do not limit the scope of protection.

[0023] The present embodiment provides a stainless steel surface treatment process, comprising the following steps:

[0024] a. Cleaning: Clean the surface of the stainless steel workpiece to remove the grease on the surface of the workpiece. The cleaning liquid used is trichlorethylene, and ultrasonic cleaning is used;

[0025] B. Sandblasting: sandblasting the workpiece surface after cleaning, adopting the method of spraying micro glass beads to remove the black scale on the workpiece surface, the micro glass bead particle diameter is 100 orders;

[0026] c. Spraying: evenly spray one or two layers of glue on the surface of the stainless steel workpiece;

[0027] d. Sintering: Put the stainless steel workpiece spr...

Abstract

A stainless steel surface treatment process comprises the following steps of a, cleaning, wherein the surface of a stainless steel workpiece is cleaned, and grease on the surface of the workpiece is removed; b, sand blasting, wherein the cleaned surface of the workpiece is subjected to sand blasting; c, spraying, wherein one or two layers of glue are evenly sprayed to the surface of the stainless steel workpiece; d, sintering, wherein the stainless steel workpiece sprayed with the glue is placed in an oven to be sintered, and a stainless steel non-stick layer is formed; e, coloring, wherein the stainless steel workpiece is subjected to coloring treatment after being subjected to anodic oxidation treatment; f, film coating, wherein the surface of the stainless steel workpiece obtained after coloring is finished is coated with a fingerprint-resistant coating, and a fingerprint-resistant film is formed; and g, drying, wherein the stainless steel workpiece coated with the fingerprint-resistant coating is dried.

Description

technical field [0001] The invention relates to a stainless steel treatment method, in particular to a stainless steel surface treatment process. Background technique [0002] Stainless steel materials have superior corrosion resistance, wear resistance, toughness and process performance (corrosion resistance, not easy to oxidize, etc.), so they are widely used in aerospace, ocean, energy, construction, chemical industry, food machinery, electromechanical industry, household appliances and other industries. With the continuous development of social economy and the gradual improvement of living standards, people urgently require high-grade color and diversified decoration of stainless steel materials. Therefore, stainless steel surface treatment technology has been widely concerned. With the increasing application of stainless steel products, especially decorative stainless steel products, some traditional single surface treatment methods can no longer fully meet people's i...
