Stainless steel tank surface treatment technology and technology implementation method
Mar 22, 2018

Stainless steel tank surface treatment is divided into surface color whitening, surface mirror light treatment, surface coloring three kinds, due to stainless steel in the process of processing, after coiling, binding, welding or artificial surface heating and baking will produce black Oxidation, so to remove the scale through a certain way, is the so-called surface color whitening.


There are two common methods for surface whitening of stainless steel tanks, one is sandblasting, and the other is using sprayed glass beads to remove the black oxide scale on the surface. There is also a chemical method that employs a non-contaminating pickling passivation paste and a non-toxic, non-toxic cleaning solution with inorganic additives to achieve whitening of the stainless steel.


The method of smooth surface treatment of stainless steel storage tanks is based on the complexity of stainless steel products and the requirements of users. Mechanical polishing, chemical polishing, electrochemical polishing and other methods can be used to achieve specular gloss, thereby improving its overall quality.


Stainless steel tank surface coloring can not give stainless steel products a variety of colors, increase product color varieties, and improve product wear resistance and corrosion resistance, the specific treatment methods are chemical oxidation coloring, electrochemical coloring, ion deposition oxidation Chemical coloring method, high temperature oxidation coloring method, gas phase cracking coloring method, etc.


These types of stainless steel tank surface coloring methods have their own characteristics, applicable occasions are also different, for example, ion-deposited oxide coloring chemical method is suitable for large quantities of product processing; and relatively speaking, gas phase cracking coloring method in the industry Less application.
