Four most important application performance for Paint products
2014.09.05 10:29Paint performance includes two aspects: coating performance and performance of the original state. It is self-evident, quality control performance of the coating for coating, paint, theoretical research has important implications for mass storage, construction.
Coating of good quality is an important guarantee of long-life protection film. Performance project paint is a lot, here only introduce some basic properties of anti corrosion coatings and coating quality of construction is important.
The relationship between the composition and viscosity of coating color flow and rheology is the study of coating, the viscosity changes in shear rate under different temperature, and the effect of viscosity of coatings and resin structure influence on the viscosity of the content. The research result can guide the production control of coating, coating pigment stability and storage stability, cans effect coatings and liquidity, coating leveling and sagging, requirements of construction coatings (brushing, spraying, roller coating etc.) and infiltration formula design, paint coating and interface bonding etc..
The fineness of the paint, pigment content is expressed in paint dispersed in the paint in the degree, but also detect whether it contains impurities affect the coating film appearance evenness. Also known as the fineness of grinding fineness. If the fineness is small, can make the coating is smooth, not only on the coating luster, appearance, performance, decoration performance can cover play a role, but also beneficial to prolong the life of.
Coating of solid content coating components of no volatilization content, refers to the coating component through the left after construction become part of the film, it's content on the formation of the coating quality and coating use value is directly related to.
Paint sagging property is a liquid coating on the vertical surface, influenced by gravity, the wet film is not dry, wet film surface easily downward flow fall, forming the upper, lower and thicker thin, serious surface to form spherical, corrugated shape. This shows that paint sagging, or the sag resistance is not good, is the coating should avoid traits.
