Yog vim li caskua colourantsuav tias yog ib qho kev hloov kho tseem ceeb rau siab -precision yas manufacturing? Nyob rau hauv lub ntiaj teb tshwj xeeb ntawm kev txhaj tshuaj molding thiab extrusion, cov khoom no feem ntau hu ua pigment npaj los yog xim paste. Nws muaj peb yam tseem ceeb: siab -cov xim xim los yog cov xim dyes, cov khoom siv ua kua, thiab cov khoom siv ntxiv. Tsis zoo li cov tsoos khoom masterbatch, uas yuav tsum tau kub siab heev thiab siab mechanical shear kom tawg tag, akua colourantyog engineered los disperse super- cov pigments tas li ncaj qha rau hauv cov kua resin nrog kev sib txhuam tsawg heev. Cov qauv tshuaj tshwj xeeb no ua rau muaj xim ntau dua qhov sib xws thoob plaws kev tsim khoom loj. Cov neeg tsim khoom tau nce mus deb ntawm cov xim qhuav vim tias cov tshuab ua kua daws cov teeb meem tshwm sim ntawm "spotting" thiab tsis sib xws. Los ntawm kev siv cov neeg nqa khoom siab heev uas tau ua tiav nrog cov khoom siv polymers xws li PP, PE, thiab PET, cov khoom siv no ua kom ntseeg tau tias lub cev kev ncaj ncees ntawm cov yas zaum kawg tseem tsis hloov pauv thaum muab lub zog, kev ua tiav.
Ua tiav kev koom ua kekua colourantmus rau hauv lub Hoobkas kev ua haujlwm muaj xws li cov kauj ruam ncaj nraim uas txo qis kev siv zog thiab cov khoom pov tseg. Cov txheej txheem feem ntau pib nrog lub tshuab ntsuas twj tso kua mis uas siv cov roj concentrated ncaj qha mus rau hauv lub caj pas pub ntawm lub tshuab, kom ntseeg tau tias qhov sib xyaw ua ke rau txhua lub voj voog. Qhov kev txiav txim siab no tiv thaiv kev ntxhov siab thiab cov plua plav cuam tshuam nrog cov hmoov, tsim kom muaj chaw ua haujlwm huv dua. Hais txog kev sib tham txog kev lag luam thiab xov xwm tsis ntev los no, cov khoom siv raw tau pom kev hloov pauv mus rau bio- cov neeg nqa khoom thiab hnyav- hlau- cov xim dawb kom ua raws li kev nruj nruj thoob ntiaj teb cov qauv. Rau cov lag luam nrhiav tswv yim txog kev sib txuam xim, xaiv akua colouranttso cai rau kev sib pauv xim sai dua thiab tsim cov txiaj ntsig zoo heev uas yuav luag tsis tuaj yeem ua tiav nrog cov khoom pellets. Nws yog ib qho tseem ceeb los khaws cov concentrates hauv qhov chaw txias, qhuav kom tswj tau lawv cov viscosity tshwj xeeb thiab tiv thaiv cov xim xim nyob rau lub sijhawm. Los ntawm kev ua raws li cov txheej txheem kev tshaj lij no, cov tuam txhab lag luam tuaj yeem lav qhov siab - zoo nkauj zoo nkauj uas ua tau raws li cov kev xav tau nruj ntawm cov tsheb, ntim khoom, thiab cov khoom siv hluav taws xob.
