      color masterbatch production process generally separation is: method, ink method, combined method, metal method this types, lower color masterbatch types production process lower specific introduction:

      1, color masterbatch production process 之冲洗 method: is material, water and 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.

       process/workflow: fine color 浆冲洗 蒸发 concentrated shrink material drying add 入载体 extrusion pelletizing

      2, ink method: 顾名思义, is in color masterbatch production in using/adopting 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 and resin mixed combined, rear through 二辊塑炼 machine （也叫 di 辊开炼 machine ）进行塑化, through mono screw or di screw extrusion machine pelletizing.  

      process/workflow: material coarse color 浆三辊研 abrasion fine color 浆二辊塑炼 extrusion pelletizing        

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

     4, combined method: is will material and property 载体掺 mixed rear, utilizing material hydrophilic this features, through combined make material from water versus 冲洗进入油 versus. meanwhile also property will material surface 包覆, make material dispersion stability, anti material poly.
