Description

[0002] With the development of modern architecture and industry, the requirements for fire safety are becoming increasingly higher. Fire retardant coatings, as an important fireproof material, are widely used in construction, transportation, ships, electricity and other fields. When a fire occurs, fire retardant coatings slow down the spread of fire through their unique flame retardant properties.

[0003] In the production of fire-retardant coatings, the quality of fire-retardant coatings is closely related to the degree of mixing between materials. The stirring device is one of the key equipment in the coating preparation process.
