    polyethylene wax R-(CH2-CH2)n-CH3, molecular weight 1000-5000, is white, 无味, inert property material 质, can 104-130 摄氏 degree lower melt, can in high temperature solvent understanding solvent agent and resin in, in drop temperature still 会析出, it fine degree and cooling speed degree has 关: slow speed cooling to relatively coarse pellets （5-10μm）, fast speed cooling relatively fine pellets （1.5-3μm）. in powder coating material formed film process in, coating film cooling, polyethylene wax from coating liquid in 析出, formed fine micro pellets, in coating film surface, to 纹理, light, slip 爽, resistant scratch applications; selection micro powder wax and coating material system can to various 花纹. lower 面赛诺 small 编 讲 understanding lower polyethylene wax in coating material in has what application?

      一, anti slip, anti viscous 连, resistant 污渍

      　 viscous is film surface and outer material viscous and viscous property, film between versus 互接触而 viscous, in large gas in 沾灰, 沾污以 and pressure bonding. 乳胶漆挥发 property tool has pressure viscous property and hot viscous property and hot, light, chemical and material chemical 引起都 aging degradation generate viscous property, property material oxidation and separation understanding, fiber material fine separation understanding and other. printing speed degree add fast more increase coating film anti viscous requirements. wax additives is anti viscous most selection. in coating film in, wax additives from film inner uniform dispersion 状态逐步迁移 to film surface upper. due to this type of 迁移, can make film surface anti-blocking, meanwhile generate resistant abrasion loss, resistant and other 同步效应. wax in coating film in how to to surface upper, this and wax and coating material to versus function, drying 形式, film thick degree, wax force degree, dispersion 状态以 and wax density has 关, coating film in 氨挥发, or 氨离子 by metal 离子取代, make wax micro hydrophilic water property. tool has hydrophobic water property wax micro easy from film in 析出. wax from film in 析出, 改变 漆 film surface formed, coating film surface force generally resin surface force 40-50mN/m, reduce to 30mN/m left right. use PTFE wax, surface force can reduce to 18.5mN/m left right, has obvious anti-blocking and resistant function

      　二, wear resistant scratch, resistant 划伤

          gloss degree is film surface its upper light toward direction injection shot can force, light amount large, gloss degree high. to coating film surface to wax micro 粒, through 折射, expand dispersion and other, make in coating film surface and other light toward direction decrease low, to light 效果. different degree and product types wax micro powder, its light large same, from full maintain gloss to deep degree light

         三, anti 流挂, resistant 沉淀

      polyethylene wax density low 0.95g/cm3), micro powder ratio surface large. material in 当离子 by coating material separation in metal 离子取代, for coating material separation （ metal material ） tool has property. polyethylene wax material add 入, increase coating material resistant 沉淀, resistant property can.

        四, light       

      gloss degree is film surface its upper light toward direction injection shot can force, light amount large, gloss degree high. to coating film surface to wax micro 粒, through 折射, expand dispersion and other, make in coating film surface and other light toward direction decrease low, to light 效果. different degree and product types wax micro powder, its light large same, from full maintain gloss to deep degree light
