Shanghai Daoqin Plastics Co., Ltd.

        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:

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

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

        3. masterbatch dispersion property good or resin 塑化不 good.

         process can as lower debugging:

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

        2. to injection molding machine add back pressure.

        如经 above debugging still good, can can is masterbatch, resin dispersion property or issues, and color masterbatch manufacturing 厂商联系 solution.

        二, use certain types masterbatch rear, products relatively easy 破裂

         this can can is due to production selection dispersant or additives quality good formed expand dispersion solvent defect, effect/influence products material mechanical properties.

        三, masterbatch, resin and formulation, different injection molding machine product 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, upper phenomenon 就会出现.

        四, 换另一 types resin rear, masterbatch and formulation, color 却发生 变化

         different grade resin its density and melt flow index has 差别, therefore resin property can has 差别, and masterbatch 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.

        五, 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.

        六, has injection products gloss good

         has below/following multiple can can:

        1, injection molding machine nozzle temperature degree low

        2, injection molding machine mold light degree good

        3, products molding cycle long

        4, masterbatch in titanium powder more

        5, masterbatch dispersion good

        七, ABS masterbatch especially easy Color Difference

        各国 production different grade ABS Color Difference relatively large, make grade ABS, 每批批号也 can can in Color Difference, use masterbatch color rear 当然也会出现 Color Difference. this is due to ABS features 引起, in upper also has solutions. is, this type of Color Difference generally is heavy. use in use ABS masterbatch 时, must attention/notes ABS this features.

        八, masterbatch 说明书 upper ratio/proportion use rear, color deep （ shallow ）

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

        1. masterbatch 未经认 true color, material less or more

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

        3. 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

        4. 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, still in issues toward color masterbatch production 厂家联系.

        九, plastics Color Matching products 发生褪 color

         plastics color products multiple factors effect/influence 会发生褪 color. plastics color products color and color powder lightfast property, resistant oxygen property, heat resistant property, resistant acid alkali property and use resin features has 关. lower is for plastics color 发生褪 color factors detailed analysis:

        1. color agent lightfast property

         color agent lightfast property effect/influence products color, strong/high light 照射 室 outer products, use color agent lightfast (resistant 晒) and other grade requirements is important indicators, lightfast and other grade 差, products in use in very fast color. weather resistant products selection lightfast and other grade low grade, most good selection 七, grade, inner products can 选四, grade.

        载体 resin lightfast property can for color 变化也 has relatively large effect/influence, outer 线引发 resin rear its separation structure 发生变化出现褪 color. in material in add outer absorption agent and other light stabilizer, can improve/increase color agent and color plastics products lightfast property can.

        2. heat resistant property

        颜 material heat stabilized property is in processing temperature degree lower material hot heavy, color, color degree. machine material formed is metal oxidation material, salt type, heat stabilized property good, resistant thermal properties high. has machine combined material material in temperature degree lower 会发生 separation structure and a small amount of separation understanding. especially is PP, PA, PET products, processing temperature degree in 280℃ above, in color agent 时一方面 need heavy material heat resistant degree, 一方面 need 考虑颜 material heat resistant time, usually requirements heat resistant time is 4-10min.

        3. resistant oxidation property

         certain has machine material in oxidation rear large separation degradation or other 变化而逐渐褪 color, process is processing in high temperature oxidation, is strong/high oxidation agent (如铬黄 in acid 根)发生 oxidation. color 淀, nitrogen material and mixed combined use rear, color 会逐渐 decrease 退.

        4. resistant acid alkali property

         color plastics products color and color agent chemical resistant product property (resistant acid alkali property, resistant oxidation also property) has 关. 如钼铬红 resistant dilute acid, for alkali 敏感, 镉黄不 resistant acid, this types material and aldehyde resin for certain color agent strong/high also function, heavy effect/influence color agent heat resistant property, weather resistance 并发生褪 color.

        针 for plastics color products color, according to plastics products processing conditions and use requirements, for material, material, surface active property agent, dispersant, resin and anti aging additives upper property can comprehensive rear can selection.
