Quality Control Method for Antistatic Floor Paint Material Production

1. Anti-static floor paint materials should be suitable for the selection of raw materials, such as dispersant: If poor dispersant materials are selected, it will disperse electromica powder for a long time, which may lead to the fracture of conductive mica powder and affect the conductivity. If suitable dispersant is selected, in order to reduce the shear stress and shortest time, the conductivity of electromica powder will be affected. Conductive mica powder is well dispersed to avoid the consequence of poor conductivity of antistatic floor paint materials.

2. Stability of products: Anti-sedimentation agent is the raw material that affects the stability of anti-static floor paint materials. The most suitable anti-sedimentation agent is selected in production to make conductive mica powder uniformly dispersed in the system, so as to improve the storage stability of coatings, the stable performance of products and the uniformity of the resistance value of coatings.

3. Viscosity control: Filler is the key to increase and decrease the viscosity of antistatic coatings. The proportion and quality of filler are very important. It can make conductive mica powder disperse more evenly in coatings and make resistance more uniform. On the other hand, it can reduce conductive mica powder. Control the appropriate viscosity by adding the amount. The viscosity of antistatic coatings not only determines the storage stability of the coatings, but also plays an important role in the resistance value of the final coatings.

4. Curing time control of coatings: The initial curing time of materials will affect the resistance value of coatings and the uniformity of coatings. Whether it is primer coatings, intermediate coatings or surface coatings, too long curing time will affect the duration of construction and the difficulty of construction, as well as the quality of engineering.
