Какую производительность и как определяет антиосадочный агент?
Антисептик представляет собой химическое вещество., обычно используется в красках, красители, клеи и другая продукция, который может предотвратить появление пигментов, наполнители, particles and other substances from settling, to maintain the uniformity and stability of the product. The anti-settling agent usually achieves the anti-settling effect by electrostatic interaction or adsorption with the surface of solid particles in the paint. The common antisettling agents are organic amines, polyacrylamide, polyvinyl alcohol and so on.
