Core tip: most of the exterior wall coating is color coating, so most of the exterior wall coating needs color matching, which involves the compatibility between the coating and the color paste, that is, the color matching of the white base paint The color matching is shown in the following aspects: The balance of hydrophilicity and lipophilicity between the base paint and the color paste has little or no floating phenomenon in the barrel The affinity between the basic paint and the color paste is balanced, and the movement of various particles is balanced during the drying process of the coating, so as to reduce the floating color of the coating - dynamic floating color The basic paint of color matching has good performance for all kinds of color pastes Influence coating on pigment Exhibition Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: most of the exterior wall paint is color coating, so most of the exterior wall paint needs color matching, which involves the compatibility between paint and color paste, that is, the color matching of white basic paint The color matching performance is shown in the following aspects: the hydrophilic and lipophilic balance between the base paint and the color paste, and there is no or little floating (static) color phenomenon in the barrel The affinity between the basic paint and the color paste is balanced, and the movement of various particles is balanced during the drying process of the coating, so as to reduce the floating color of the coating - dynamic floating color The basic paint of color matching has good performance for all kinds of color pastes The influence of the coating on the color of the pigment is the type of emulsion, wetting agent, dispersant type and PVC size Generally, the hydrophobicity of strong emulsion has good chromaticity for carbon black and phthalocyanine and other nonpolar or weak polar pigments Hydrophobic dispersants have a better color developing ability than those of affinity water dispersions The paint with poor color rendering can be improved by adding suitable wetting agent The non-ionic wetting agent such as low HLB value Hydropalat 188A, high HLB value Hydropalat 436, Hyo NIC PE-100, anionic wetting agent Hydropalat 875, different color paste emulsion system can choose different wetting agents Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
