色母料的作用(Therole colormasterbatch) Masterbatch firstlydeveloped countries WesternEurope Chinastarts late, late70 Beijing,Shanghai beginresearch trialproduction; mid-1980s,Beijing yanshan petrochemical guangdongxinhui began introducewet dryprocess technology equipmentfrom Ciba Geigy,Hoechst othercompanies. technicalprocess colormasterbatch colormasterbatch wetprocess. colormasterbatch grinding,rotating, washing, drying water.Only waycan guaranteed.Pigments grindingprocessing sametime, also should undertake technicalinspection masterbatch,determination sandingslurry fineness, abrasiveslurry performance, determining solidcontent sandslurry printingink fineness, etc. What colormother? Why use colormother? colormother anothername, which polycollation,which resin.Several benefits colormother: chemicalstability Makepigment better dispersion Simpleprocess turncolor; non-contaminatedarticles; Save time rawmaterials. Due directcontact air,so moisture,oxidation, cluster, directly use plasticproducts surface color darkcolor, colorfade easily changed, dustyduring mixing, affect productionthrough mechanicalprocessing, refined processing paint,paint resincarrier, dispersant, fully mixing, make pigmentfrom air,water, thereby enhancing pigment,improves tintingstrength, color light. Because resinparticle shape, so more convenient measurement,mixed won't stick container,so saved clean containers machinetime cleaningmachine used rawmaterials. basiccomposition colormother organicpigments inorganicpigments. commonlyused organic pigments phthalocyanine,phthalocyanine blue, phthalocyanine green, suntan, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red, etc. commonlyused inorganic pigments cadmiumred, cadmium yellow, titanium white powder, carbon black, iron oxide red, iron oxide yellow threepigments project dye Organic pigments Inorganic pigments source Natural syntheticsynthetic Natural clearplastic whitebody lowconcentrations, translucentCan't transparentConcentration coloringbig medium small brightness big medium small Light stability poor medium strong Transport phenomena big medium small specialcolor mother chooses sameresin alsoconsider carrier'sfluidity. dispersantDispersants cause disperseuniformly longercondense. meltingpoint dispersantsshould lowerthan goodcompatibility goodaffinity mostcommonly used dispersants polyethylenelow molecular wax, stearate.

Variety colormother classificationmethods colormother commonlyused followingcategories: Classification PE,PP, ABS, PVC, EVA, etc. Classification: injectioncolor mother, blow molding mother, spinning mother varietiescan differentgrades, Seniorinjection color mother Used cosmeticpacking box, toys, electric shell otheradvanced products. General injection color mother Used generaldaily plastic products, industrial containers, etc. Superiorblown film mother Used ultra-thinproducts. Normalblown film mother Used generalpacking bags, woven bags plasticcoloring. Spinningmother dyeingtextile fiber, colouringforce heatresistance, lightresistance Lowerlevel color mother Used manufacturinglow gradeproducts garbagecan levelcontainers. colormasterbatch colormother verysimple, presscertain ratio plasticresin mixadequately, cooperate allsorts differentplastic processing craft requirement, extrusion molding can. Need payattention changecolor, hopper must primarycolors addplastic screw cleaner machine residual material rinsedclean, replace newscreen pack, bestuse morethan 100 mesh filter; Note colorchanges. colormother productcost mostcases somecases, using masterbatchcoloring rather than using tonercoloring economy, colouristcan through several lower price pigment combination achievehigher prices pigment shading effect. Consider followingtwo phenomena: manycases, when used tonercolor matching plastic products manufacturer mosteconomic, colormatching when verycommon. colormother does Coloringmother coloring products usetoner coloring products its class higher,higher prices oftenhigher than increasecosts, so masterbatch can create "profits" instead. somecases, colorparent coloring moreeconomical than colorpowder. plasticproducts Productsurface granulation: Main reason: materialcylinder diehead have impurity; toolong. colormother colorpowder filterscreen has been perforated. Processing method: moldingmachine normaltemperature, start moldingmachine, greyplastic resin slowestspeed clean-up,unwrapped die head cleaning when necessary, timelyreplacement filter.Switch decentralizedcolor Unevendiffusion: Main reasons: colormother rawmaterials; plasticizingeffect machineitself toosmall. Treatment methods: fully stir, adjust temperatureproperly, change colormother rawmaterial, replace other machine production, adjust colormother. Frequentlybroken materials Main reason: incorrect;Poor affinity rawmaterials; motherdispersion verybad; coloredmothers toohigh. Treatment: adjust accurate,replace rawmaterial, replace goodcolor mother colormother. Colorchanges: Main reason: rawmaterial background color colormother coloredpowder used toohigh. clean;Change processingtechnology; colorpowder itself has color difference; Improper collocation watermouth; uncontrollable.Treatment: use samecolor water.Thoroughly clean moldingmachine, feeding door mixingmachine; suitablecolor, suitable color color;Use stable processing techniques.
