Shanghai Daoqin Plastics Co., Ltd.

         color masterbatch is types new type polymer/macromolecule material color agent this type of excellent color property can, masterbatch material in use process in 会出现一 issues, lower 面我们 specific understanding lower causes and solution methods:

        一, in cationic light lower, products in has strip/profile 纹状 颜 material belt/tape:

         from plastics material mechanical properties and plastics molding process 两 方面考虑:

         injection molding equipment temperature degree has control good, masterbatch mixing/compounding rear can and resin separation mixed combined;

         injection molding machine has add back pressure, screw mixing/compounding 效果不 good;

         masterbatch dispersion property good or resin 塑化不 good.

         process can as lower debugging:

         will mixing/compounding 腔靠落 material separation temperature degree add improve/increase;

         to injection molding machine add back pressure.

        如经 above debugging still good, can can is masterbatch, resin dispersion property or issues.

        2, use certain types masterbatch rear, products relatively easy 破裂:

         selection dispersant or additives quality good formed expand dispersion solvent defect, effect/influence products material mechanical properties.

        3, masterbatch 说明书 upper ratio/proportion use rear, color deep / shallow:

         this issues although simple, in very more can can property, specific is:

         masterbatch 未经认 true color, material less or more;

         use amount 不准确, inner enterprise especially is in small enterprise 随意计 amount phenomenon a large amount of in;

         masterbatch and resin 匹配存 in issues, this can can is masterbatch selection 不当, can can is 厂家随意改变 resin product types;

         machine temperature degree 不当, masterbatch in machine in time long.

        处理程序: 首先检查 resin product types is and masterbatch 匹配, amount is 否准确, its adjustment machine temperature degree or speed.

        4, masterbatch, resin and formulation, different injection molding machine product is color has deep shallow?

         this is injection molding machine causes 引起. different injection molding machine manufacturing, use time or maintenance different, formed machine 械状态 差别, especially is add hot parts and material 筒 紧贴程 degree 差别, make masterbatch in material dispersion 状态也不一样.

        5, masterbatch in process in 发生颜 material phenomenon is effect/influence products quality?

         has masterbatch material content (or material) very high, in this type of lower, 发生迁移 phenomenon belongs to positive 常. especially is add material masterbatch, 会发生严 heavy phenomenon. this effect/influence products quality, is masterbatch injection formed products rear, material in products in positive 常 显 color concentrated degree.

        6, 换另一 types resin rear, masterbatch and formulation, color 却发生 变化, this is is what?

         different grade resin its density and melt flow index has 差别, therefore resin property can has 差别, and masterbatch versus property has 差别, from 而发生 color 变化, generally 说, need its density and melt flow index versus large, that color 差别也不会太 large, can through adjustment masterbatch use amount relatively positive color.

        7, is what has injection products gloss good?

         has below/following multiple can can:

         injection molding machine nozzle temperature degree low

         injection molding machine mold light degree good

         products molding cycle long

         masterbatch in titanium powder more

         masterbatch dispersion good

        8, time rear, has plastics products 会发生褪 color phenomenon:

         using/adopting basic material quality good, 发生漂移 phenomenon.
