Kev tsim cov yeeb yaj kiab ua ntej-coated feem ntau suav nrog ntau theem tseem ceeb: kev npaj substrate, txheej, thiab kho. Ua ntej, lub substrate yuav tsum tau ntxuav, degreased, thiab nto - kho kom ntseeg tau tias muaj zog zaj duab xis adhesion. Cov hlau substrates feem ntau phosphated los yog primed, thaum cov yas substrates yuav tsum tau tshem tawm cov hluav taws xob zoo li qub thiab cov impurities saum npoo. Tom ntej no, txheej txheej yog tsim, nrog rau kev sib xyaw thiab homogenization ntawm resins, pigments, thiab additives, kom ntseeg tau tias kev ruaj ntseg ntawm zaj duab xis lub cev thiab tshuaj lom neeg. Cov txheej txheem txheej yog ces uniformly siv rau substrate nto siv txoj kev xws li cov menyuam txheej, txau, los yog dip txheej. Kev tswj cov yeeb yaj kiab thickness thiab uniformity yog qhov tseem ceeb nyob rau theem no.
Tom qab txheej txheej, cov yeeb yaj kiab ua ntej-coated yuav tsum tau ua kom qhuav los yog kho kom tsim cov txheej ruaj khov. Cov txheej txheem muaj xws li thermosetting, UV curing, lossis electron beam curing. Cov txheej txheem sib txawv muaj qhov sib txawv ntawm cov txheej txheem txheej, xws li huab cua tsis kam, tiv thaiv corrosion, thiab yoog raws. Cov yeeb yaj kiab kho tau tom qab ntawd yuav tsum tau txias, dov, lossis txiav rau tom ntej cia thiab thauj mus los. Tag nrho cov txheej txheem ntau lawm hais txog kev tswj xyuas nruj thiab kev tshuaj xyuas zoo. Los ntawm kev tswj cov txheej txheem kev tshawb fawb, nws tuaj yeem ua kom ntseeg tau tias cov yeeb yaj kiab ua ntej -coated ua tau raws li cov qauv kev xav tau ntawm kev ua haujlwm ntev, adhesion, thiab kev zoo nkauj ntawm qhov chaw, txaus siab rau daim ntawv thov kev xav tau ntawm ntau yam xws li kev tsim kho, khoom siv hauv tsev, thiab kev thauj mus los.
