Antiseptic coating for northwest silica sand pickling tank of Zhisheng manufacturer - technical guidance

Analysis and Introduction of Application Effect of Coatings in Silicon Industry

What are the application scenarios of special coatings in silicon industry and quartz sand industry, and what are the application effects?

1. Application of anti-corrosion coating:

(1) The quartz sand pickling tank is coated with ZS-1033 hydrofluoric acid resistant anticorrosive paint, which can prevent the corrosion of the pickling solution on the metal tank body, and can extend the service life of the tank body by half to one year. Pay attention to the changes of temperature and humidity when cleaning the tank after the end of the production cycle. Slow cooling and moisture extraction are good maintenance methods for the anticorrosive coating, which can reduce the temperature Delamination caused by mismatch of expansion coefficient between coating and substrate due to humidity change;

(2) The sewage concentration tank uses ZS-1032 strong oxidation resistant anti-corrosion coating, which can prevent the corrosion of the mixture of acid, non inorganic solvent, salt and other corrosive media in the sewage. The film forming material of the tetrafluoro system is used, and the temperature resistance can reach 250 ℃. According to different corrosion components, it can play a good protective effect in 2~3 maintenance periods;

(3) The acid solution is stored in a centralized workshop, including the tank outer wall, workshop steel structure, workshop floor, cofferdam and other areas. According to the type and concentration of acid in the storage area, ZS-1032, ZS-1033, ZS-1034, ZS-711 and other acid and alkali resistant anti-corrosion coatings can be used, and the anti-corrosion level can reach above C5;

2. Application of heat preservation, sunscreen and cooling, and energy-saving coatings:

In view of the problem of high temperature control pressure in the workshop in summer, ZS-221 sunscreen and thermal insulation coating can be used, which has the functions of radiation cooling and reflection of solar heat. According to the weather conditions in summer, the roof surface temperature can be reduced by about 10~30 ℃, the indoor temperature control pressure can be reduced, the energy consumption can be reduced, and the role of energy conservation and emission reduction can be played.

The above materials are products with relevant applications in the silicon industry, which are relatively mature, and can be fine tuned according to the corresponding working conditions.
