Thick type reported in 2018 Fire retardant coating 1kg price
Thick type fire protection reported in 2018 coating 1kg quotation, non expansive steel structure fire-retardant coating qualified in GB14907-2018 inspection is sold in batches, and thick fire-retardant coating reported in 2018 The main component is inorganic thermal insulation material , Granular surface , Low density , The coating will not expand when heated , Because of its good thermal insulation , Therefore, it is also called thermal insulation fireproof coating. Its fire prevention mechanism is to use the inherent good thermal insulation of the coating , Prevent fire heat from transferring to steel , And form a dense glaze at * * * temperature , It can effectively isolate oxygen and reflect heat , Delay the temperature rise of steel structure , It plays the role of fire protection.
Base treatment method
Of the protected steel substrate surface treatment It is the basic process of thin steel structure water-based fire retardant coating construction. The purpose is to create a good condition for the adhesion of the coating film to the surface of the protected steel substrate, while improving the performance of the coating film.
Steel structure surface treatment is a key to achieve good results in the whole painting process key Link.
Purpose of surface treatment,
1、 Remove all kinds of dirt on the surface of the coated object to make the coating adhere to the surface of the coated steel substrate well, so as to ensure that the coating has excellent performance.
Dirt can be divided into inorganic and agricultural production system dirt. Their presence not only affects the appearance of the coating, but also seriously causes the film to flake off,
Second, the surface of the protected object shall be trimmed to remove the existing defects, and the surface roughness required for the construction of fire retardant coating shall be provided, so that there is a good adhesion foundation when painting.
Practice shows that the proper roughness of the surface of the coated object is forty-six Level.
Painting essentials ：
The coating of fireproof coating is to evenly apply the coating on the surface of the protected object. The quality of coating directly affects the quality of coating film. Suitable painting methods and equipment shall be used for different protected objects and different fire retardant coatings. In order to obtain better film quality, brush coating method and roller coating method are adopted simultaneously in this project 。
