How to choose paint for different parts of cryogenic storage tank

The excellent anti-corrosion performance of cryogenic storage tanks is half of the reason for anti-corrosion coatings, but there are many problems that need to be paid attention to when applying anti-corrosion coatings for cryogenic storage tanks. For example, how to choose the correct paint for different parts of a cryogenic storage tank? The specific methods are as follows:
 
It is necessary to know that part of the excellent anti-corrosion performance of anti-corrosion cryogenic storage tanks comes from anti-corrosion coatings, so the selection of anti-corrosion coatings is a very important task, which will affect the anti-corrosion quality and effect of cryogenic storage tanks. Moreover, if the correct anti-corrosion coating is selected, it will also play a beneficial role in the use of anti-corrosion cryogenic storage tanks.
 
Of course, the anti-corrosion coatings used on different parts of the anti-corrosion cryogenic storage tank are also different. Generally, carbon-based electrostatic conductive coatings are used on the inner surface of the anti-corrosion cryogenic storage tank. . Therefore, its anti-corrosion effect is not very good, especially after long-term use. Nowadays, non-carbon static conductive anticorrosive paint is used, because it can solve this problem and has a very good anticorrosive effect. The outer surface of the anticorrosive cryogenic storage tank is generally made of external anticorrosive paint, such as chlorinated rubber paint, and ordinary polyurethane paint. However, in a high temperature environment, there may be some unsafe factors. Therefore, considering various factors, it is more appropriate to use heat insulation reflective paint, which can play a role in heat insulation and cooling, thereby avoiding the above problems.
 
There is also the outer surface of the bottom plate of the anticorrosive cryogenic storage tank. Generally, asphalt or epoxy coal tar paint is used. However, from the perspective of application, the effect is still lacking. Therefore, for comprehensive comparison, it is recommended to use water-based lithium silicate zinc-rich paint. This kind of coating has the advantages of simple construction and good environmental protection, so in some aspects, it has a very good anti-corrosion effect.
