The chemical combustion engineering technology of stainless steel forward position

The chemical combustion engineering technology of stainless steel forward position

Stainless steel was had high strenth, tall hardness, tall wearability, tall anti-corrosive reach the superior performance such as easy treatment, apply at all sorts of domains widely, be in particularly adornment industry, have its advantage. The country is at present explicit of stainless steel chromatic in also be in advance rapidly, but still do not have quite reliable theory and application, the black with the following commonner introduction is chromatic with color chromatic law:

The common stainless steel pool in the life, stainless steel cistern, stainless steel armrest is waited a moment, these are to belong to articles for daily use, the stainless steel workbench that still have even if can use on industry. It is with stainless steel cistern among them exemple, modelling of stainless steel cistern beautiful, economy is practical.

One, the black of stainless steel oxidizes
1, heat treatment law
The bath of heavy chromic acerbity sylvite that puts stainless steel product in melt (385 ℃ - 400 ℃ ) in, handle 20-30min, after taking out refrigeration, clean in clear water, can get firm, even black oxidation film.

2, chemical oxidation law:
Attainable in following solution even black oxidation film:

2, the chromatic oxidation of stainless steel is chromatic:
Stainless steel oxidation is to point to, in solution, as the different facial expression that time differs and receives. Its mechanism interferes generation as a result of light namely, light passes metallic surface film, happen to the light such as reflection, reflex interferes a phenomenon and present different color. Because velar ply is different, different also to smooth reflection, reflex, and the interference with different generation is lubricious. Following introduction uses a kind of wider chemical and color technology one kind

Inside formulary temperature limits, as the extension of time, the order that generates color is: Bronze color, blue, golden color, gules, green.
Usually, raise high temperature, quality time shortens; But when temperature under 70 ℃ when, win satisfactory color hard, if temperature is exorbitant, solution evaporates big, change big, time is controlled hard; The stand or fall of goods surface also affects the result with chromatic oxidation directly, if exquisite surface, it is easier that do that color rises, even and onefold; Stainless steel is in chromatic before must electroanalysis polishing.
