how to identification color masterbatch quality good bad?

very more for color masterbatch 而言看似 very 陌生却 also 如此之熟悉, has use, tool has color 泽明亮, 鲜艳夺目, color strong/high degree high, dispersion property good, concentrated degree high, degree good, cover/cap force strong/high, resistant property and heat resistant property good and other features, by widely used in injection molding, blow molding, wire drawing, 流延, 挤塑, film, foaming, sheet/slice 材, pipe/tube, 抽粒, in 空, EVA, bottle, sheet/slice 材, use electrical appliances, toys, packaging materials, electrical and cable, plastics bag, automotive, building materials, and use product, packaging bag, packaging bottle and other plastics products industry.

how to identification color masterbatch quality good bad?

不妨先 understanding lower 白 color masterbatch main/primary technology indicators:

1, resistant property (grade)[≥4]

2, moisture content (%)[≤0.30]8, Color Difference [≤1.50]

3, melt temperature degree (℃)[125～200]

4, color masterbatch dispersion property: [无 color 点, strip/profile 纹]

5, resistant property (grade)[5-8]

6, color masterbatch appearance 粒状, pellets uniform, color 泽一致

7, heat resistant property (grade)[≥4]

if color masterbatch combined upper 面几点 indicators requirements, can 判断该白 color masterbatch quality is good.

白 color masterbatch use precautions

一, is decrease/reduce Color Matching rear fiber Color Difference, for color masterbatch need dilute 释, control mixed ratio/proportion, long filament less 于3%～10%, short less 于1%～3%, mono color 膨体连续 long filament use color equipment made, color masterbatch must in mixed combined rear 输入挤 pressure machine, meanwhile is increase melt mixed combined can force, can in pressure machine increase mixed combined plant/unit.

二, color masterbatch mixed methods in color filament color formulation rear, will color masterbatch in front uniform dispersion in 丙纶切 sheet/slice in, is ensure product quality key/critical, specific mixed methods has type. its is heavy method and method, in pressure machine in or rear will color masterbatch melt rear, use small pressure machine 注入丙纶 melt in, uniform property very good.

三, selection color masterbatch 时, need selection scope/range selection, color masterbatch has fine grade, coarse grade separation, coarse grade color masterbatch color can used for fine grade Color Matching, Color Matching 时应考虑纺 made fiber Monofilament 旦数, selection type grade 别 白 color masterbatch.

四, selection color masterbatch most good is production product, is reduce cost selection high concentrated color masterbatch. color masterbatch material has high, in, low separation, Color Matching according to formed quality requirements, selection different grade 别 白 color masterbatch. is 避免因颜 material light, heat stabilized property different 而引起 formed product fiber quality 变异, Color Matching also selection combined fiber quality requirements, tool has same light, heat stabilized grade 别 白 color masterbatch color, coarse fiber ratio fine fiber need concentrated degree low, its color masterbatch application ratio positive ratio 于纤旦数 平方根.
