preparation example Construction

[0019] The invention provides a preparation method of a stainless steel product, which uses a plasma plasma polishing method to polish the stainless steel product to improve brightness, remove deep defects on the surface of the stainless steel product, and improve the appearance effect. The preparation method of the present invention is different from the existing plasma plasma polishing method in that: the polishing salt of the present invention is made up of the composition of two kinds of action mechanisms, comprises the first polishing component that plays macroscopical removal effect and plays the role of microscopic finishing. The second polishing component. The first polishing component contains sodium sulfate and / or potassium sulfate; the second polishing component contains nitrate and complexing agent. During the plasma plasma polishing process, the macro-removal component can quickly and uniformly dissolve the surface of stainless steel products and remove its deep p...

Embodiment 1

[0040] This embodiment 1 is used to illustrate the stainless steel products provided by the present invention and the preparation method thereof, and the preparation method of the stainless steel products comprises the following steps:

[0041] Step 1. Preprocessing

[0042] The prepared wax removal water (the volume concentration of the wax removal water is 6 V%) is heated to 80°C at a constant temperature, and the stainless steel product C1 to be treated is immersed in the wax removal water, stirred and soaked for 4 minutes, then taken out; then in 80°C deionized water Take it out after stirring and soaking for 0.5min; then rinse it with deionized water at room temperature;

[0043] Step 2. Plasma plasma polishing

[0044] Prepare 10L polishing liquid, described polishing liquid comprises: the sodium sulfate of component A:15g / L; Corrosion inhibitor), 3g / L disodium EDTA as a complexing agent, and the above-mentioned components A and B were prepared into a polishing solutio...

Embodiment 2

[0048] This embodiment 2 is used to illustrate the stainless steel product provided by the present invention and the preparation method thereof, and the preparation method of the stainless steel product comprises the following steps:

[0049] Step 1. Preprocessing

[0050] The prepared wax removal water (the volume concentration of the wax removal water is 10 V%) is heated to 75°C at a constant temperature, and the stainless steel product C1 to be treated is immersed in the wax removal water, stirred and soaked for 3 minutes, then taken out; then in 75°C deionized water Take it out after stirring and soaking for 0.5min; then rinse it with deionized water at room temperature;

[0051] Step 2. Plasma plasma polishing

[0052] Prepare 10L of polishing liquid, which includes: Component A: 35g / L potassium sulfate; Component B: 8g / L sodium nitrate, 1.82v% polyethylene glycol 600 as a brightener (also used as a corrosion inhibitor), 3g / L disodium EDTA is used as a complexing agent,...

Abstract

The invention provides a stainless steel product and a preparation method thereof. The method comprises the steps that: a stainless steel substrate to be processed is adopted as an anode and is placed in an electrolytic tank containing a polishing solution; and under the condition of plasma polishing, the stainless steel substrate is polished, such that the stainless steel product is obtained. The polishing solution comprises a first polishing component and a second polishing component. The first polishing component comprises sulfate selected from sodium sulfate and / or potassium sulfate. The second polishing component comprises nitrate and a complexing agent. The invention also provides the stainless steel product prepared through the preparation method. According to the preparation method provided by the invention, a polishing salt formula different from that of existing plasma polishing is adopted; and components with different action mechanisms are reasonably formulated. On a basis of environment protection and cost reduction, a better mirror effect is provided for the surface of the stainless steel product.

Description

technical field [0001] The invention relates to the field of surface treatment of metal materials, in particular to a stainless steel product and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the increasing requirements of people for products, the requirements for the appearance of metal products, such as stainless steel products, are getting higher and higher, especially for the comprehensive requirements of product roughness and brightness. Polishing can be used as a metal The terminal process of surface treatment of structural parts and decorative parts can effectively improve their surface performance and enhance the decorative effect. It can also be used as the pre-process of various surface treatment terminal processes (such as: anodic oxidation, micro-arc oxidation, electroplating, PVD, etc.), polishing The quality has a great influence on improving the decorative effect of the surface treatment terminal...
