ColorMasterbatch) firstdeveloped WesternEuropean countries, Chinastarted late, 70s,Beijing, Shanghai beginproduct development BeijingYanshan petrochemical GuangdongXinhui gradually from Ciba-Geigy, Hoechst, dryprocess ourcountry masterbatches industry entered rapidgrowth. Masterbatch technology requirements verystrict, generally used masterbatchtechnology wetprocess. Masterbatch material grinding waterphase, phase, washing, drying, granulation, onlyway ensureproduct quality. Other pigments grindingprocessing sametime, should also colordetection technology, sandslurry diffusionproperties sandslurry, determination sandslurry solid content finenesspaste project. color?Why do you want usecolor? onekind dyesuper constant uniform supported resinprepared aggregates. Some usingcolor masterbatch: pigmentchemical stability betterdispersion; simple,easy turncolor; environmentclean, staincontainers; savetime rawmaterials. Because directcontact air,so absorbmoisture, oxidation, agglomeration phenomenon, direct use plasticproduct color, dark color hue, easy mixingcaused dusty,affecting operatingpersonnel. productionprocess after machining, resincarrier, dispersant sufficient mixing, air,water separation, thus increasing pigmentweatherability, improve pigment dispersion tintingstrength, bright color. resinparticle shape similar,so more convenient itsmeasurement, mixing does container,thus saving clean container machinetime rawmaterials used cleaningmachine. basiccomposition, color two pigmentconsists organicpigments inorganicpigments. Organic pigments commonlyused: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light red, red, yellow, large molecular molecular existence yellow, violet, red azo etc.. Inorganic pigments commonly used cadmiumred, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow.

Three, color variety gradeColor classification methods commonly used following:According vectorclassification: PE PP ABS Color Masterbatch, masterbatch, masterbatch, masterbatch, masterbatch otherEVA PVC; type:injection blow molding masterbatch, masterbatch, masterbatch spinning etc.; All varieties can differentlevels, advancedinjection Masterbatch Used cosmeticspackaging, toys, electrical appliances otheradvanced products. ordinaryinjection Masterbatch generalhousehold plastic products, industrial containers etc.. seniorfilm masterbatch blowmolding coloring ultra-thin products. ordinaryfilm masterbatch blowmolding coloring bags, woven bags spinningcolor masterbatch textilefiber coloring pigment, fine particles, high concentration, strong coloring, resistant gradeMasterbatch lowerproduct manufacturing colorquality requirements trash,low-level containers etc.. Four, colormasterbatch mattersneeding attention verysimple, certainproportion mixed plasticresin, differentkinds plasticprocessing technology, extrusion molding can color,must take hopperclean, plasticscrew cleaning agent machine barrel residual material clean, replace bestuse filtermore than 100 meshes; temperature colorchange. Five, coloreffect productcost mostcases somecases, ColorMasterbatch rather than use toner coloring coloring effect economy,reason colordivision severallow price pigment combination achievehigh price pigment.Consider followingtwo phenomena: manycases, plastic products manufacturers colortoner pigment mosteconomical, paint,color test repeatedly, causing human materialwaste verycommon. ColorMasterbatch coloring products tonercoloring products grades completelydifferent, littlehigher, higher prices oftenhigher than ColorMasterbatch increased cost, so cancreate "profit masterbatch". From somecases, ColorMasterbatch than colored"economy". sixgeneral problems treatmentmethods, plasticproducts surfacegrain products: mainreason: impurities;temperature rawmaterial barrelheating time toolong; colortoner filterhas perforated.

Processing method: fully mixing, temperature adjustment, appropriatemasterbatch raw materials, replacing other machine production adjustmasterbatch delivery ratio. oftenbroken material mainreason: materialcompatibility difference; colordispersion colorratio dropped too high. Processing method: adjust temperatureaccurately, rawmaterials used, excellent dispersion masterbatch, reduce replacementproportion colormasterbatch. colorchange: mainreason: rawmaterials used colorinconsistency; tonertemperature degree low,when hightemperature dischargedoor without fire; clean; change colortoner itself; materialoutlet impropercollocation; mixing machine mixingtime.
