2022-02-10

The coloring of stainless steel water tanks generally has the following conditions:

(1) Chemical oxidation dyes for stainless steel water tanks: The color solutions for chemical oxide films include dichromate method, mixed salt method, curing method, acid and alkaline oxidation.

(2) Electrochemical dye for stainless steel water tank: This is the color formed by electrochemical oxidation.

(3) High-temperature oxidation dyes in stainless steel water tanks: especially molten salt, the workpiece is immersed in certain process parameters, so that a certain thickness of the workpiece oxide film is formed and presents different colors.

(4) The shadow of gas cracking in stainless steel water tank: This method is very complicated and is rarely used in the industry.

(5) Oxygen ion chemical pigment deposition in stainless steel water tank: The stainless steel water tank is a vacuum coating and vacuum evaporation coating workpiece of this machine.
