         small is 此整理 一篇文章 introduction color masterbatch, and industry 里朋友们交流一 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 (oC)[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]

        理论 upper 讲, combined upper technology indicators color masterbatch, quality is good.

        选购白 color masterbatch need 考虑 10 方面

        1, degree

         white masterbatch degree main/primary through masterbatch in titanium powder 呈现, effect/influence titanium powder degree factors has very more, its in main/primary 包括二 oxidation titanium pellets large small, and degree distribution, types type and content and oxidation titanium pellets defect. generally 说, due to chlorine method for Raw Materials titanium powder pure degree need high and in made process 杂质也 less, therefore chlorine method titanium powder degree need ratio acid method need good. in 现实 白 masterbatch market in, less color masterbatch production through add versus and other ash content content carbon acid 钙, acid 钡, zinc titanium powder, its this machine powder 体 白 degree and titanium powder is can ratio 拟.

        2, cover/cap force

        遮 cover/cap force is color masterbatch very important indicators, cover/cap force good 意味 该颜 material color force strong/high, relatively small add amount can obtain 需 效果, color masterbatch cover/cap force 取决于 titanium powder selection and processing process, 金红石 type titanium powder versus ratio titanium type titanium powder, tool has relatively small relatively mono 位晶格, and more large rate, therefore cover/cap force and UV resistant light property can obvious need excellent titanium property, for/regarding use type type 金红石 titanium powder color masterbatch, titanium powder small, distribution narrow, in material in dispersion good cover/cap force obvious need ratio titanium powder distribution wide, in material in dispersion property can good. 同样, Common carbon acid 钙, acid 钡, zinc cover/cap force and titanium powder is can ratio.

table/sheet 1 different material 质 折射 rate

         from upper 述 折射 rate comparison can 知, 金红石 titanium powder and 载体PE resin rate versus most large, color dispersion most good, cover/cap force color force most strong/high.

        3, dispersion property

         dispersion property for titanium powder in plastics in application has important effect/influence, generally 说, titanium powder pellets fine, dispersion good, its color force strong/high degree high, and in film need fine printing 时, use dispersion property excellent 良 白 color masterbatch 图案清晰 degree, 层次感, degree more good, this is due to film micro slip degree is printing quality good bad factors 之一.

        4, water content

        白 color masterbatch in water content for/regarding masterbatch property can important effect/influence, generally water content need control 1500ppm below/following, requirements need in 600ppm below/following, in injection molding process in, generally in production front for Raw Materials drying, in film production in, 客户买 都 is and 载体预 mixed rear use, if masterbatch water content high, heavy 直接会导致破 film, has in film upper formed small bubbles, “晶点” and other defect, formed color masterbatch water high causes from masterbatch selection raw materials to process has effect/influence.

        5, odor

         has film production in use color masterbatch rear, to types odor, this in film and and food contact film in is for 不允许, this main/primary is due to color masterbatch in titanium powder in has machine process in, selection additives 不恰当 or add amount large, or masterbatch production process in selection dispersant has issues, can more color masterbatch grade.

        6, color versus selection

        金红石 titanium powder due to in light 区域反射 rate relatively low, therefore, 金红石 type titanium powder has “偏黄” color 调, “偏黄” color make by color product to 人以“陈旧”感觉, and make fine printing 图像鲜艳 degree and 层次感 decline, this in many masterbatch material use in is 不受欢迎, in titanium powder in add micro amount light increase agent rear, can absorption long 300-400nm outer light, 并转换 formed long is 400-500nm color light, this can make color masterbatch 呈“蓝 versus ”, color masterbatch use in according to need 考虑.

        7, flow property

        白 color masterbatch flow property can table/sheet is melt flow index (MI), value low flow 差, value high flow property good, flow property good processing properties good, machine low, rate consumption low, use in selection color masterbatch 时候, remove requirements masterbatch tool has good flow property, also need attention/notes masterbatch melt need and factory product in resin need combined, generally is color masterbatch MI need high 于载体 resin.

        8, printing hot property can

         white film products large more 数情况都 need printing and hot 封, color masterbatch in if add carbon acid effect/influence printing 图案 清晰 degree and degree, masterbatch in add positive or amount dispersant effect/influence hot and printing property can.

        9, resistant and weather resistance

        白 color masterbatch generally requirements resistant property to 7-8 grade, weather resistance to 4-5, resistant temperature need 达280 degree, this requirements main/primary also is 取决于 titanium powder quality, need to above conditions, must is need 金红石 titanium powder.

        10, RoHS& FDA

         heavy metal testing and food contact can is color masterbatch important indicators, is very more white film used for food packaging, through FDA food certification is must need through testing.

        白 color masterbatch use precautions

        1, 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.

        2, 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.

        3, 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.

        4, 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.
