color masterbatch use color material, color masterbatch technology upper must attention/notes color material plastics raw materials, additives between 搭配关系, its selection key points lower 述.

　　1, color material can resin and various additives has reaction, resistant solvent agent property strong/high, property small, heat resistant property good and other.

　　也就 is 说, color masterbatch can various chemical reaction. carbon can control polyester plastics solid reaction, therefore can in polyester in add carbon black material.

　　 color masterbatch technology is plastics products molding processing temperature degree relatively high, therefore color material in molding add hot temperature degree conditions lower separation understanding color.

　　 generally machine material heat resistant property relatively good, has machine material and material heat resistant property relatively 差, this in selection color material product types 时引起足够 heavy 视.

　　2, color material dispersion property, color force good.

　　 color material dispersion non-uniform 时, effect/influence products appearance property can; color material color force 差时, make color material use amount increase, material cost improves. color material in 不一样 resin in dispersion property color force 并不一模一样, therefore in selection color material attention/notes this 一点. color material pellets large small dispersion property has 关系, color material 粒径越 small, dispersion property good, color           force strong/high. color masterbatch technology process requirements very 严格, generally nano color masterbatch technology is wet method process. color masterbatch material water versus abrasion, versus, water 洗, drying, pelletizing formed, this product quality can to ensure.

color masterbatch technology process process/workflow has types methods

　　(1) color masterbatch technology process ink method: 顾名思义, is in color masterbatch production in nano ink color production methods, through 三辊研 abrasion, in material surface 包覆一层 low separation 子保护层. abrasion rear fine color again 跟载体 resin mixed combined, rear through 二辊塑炼 machine (也叫 di 辊开炼 machine)进行塑化, most rear through mono screw or di screw extrusion machine 进行          pelletizing.

　　(2) color masterbatch technology process method: is material, water dispersant through abrasion, make material pellets small 于1μm, through versus method, make material 转入油 versus, rear drying made color masterbatch. versus need use has machine solvent agent, and versus solvent agent recycling plant/unit.

　　(3) color masterbatch technology process combined method: is will material property 载体掺 mixed rear, utilizing material hydrophilic this features, through combined make material from water versus 冲洗进军油 versus. meanwhile also property will material surface 包覆, make material dispersion stability, retardant material 凝结.

　　(4) color masterbatch technology process metal method: is material 经 研 abrasion rear degree to 1μm left right, in temperature degree lower add liquid, make 每一 颜 material pellets surface uniform by liquid lubricating wet, formed 一层皂化 liquid, metal salt solvent liquid add rear in material surface 皂化层 chemical reaction formed metal 皂 保护层(hard acid 镁), this 样就          make abrasion fine rear material pellets 不会引起絮凝 phenomenon, 而保护一定 fine degree.
