Raws li cov khoom siv tseem ceeb rau kev ua haujlwm ruaj ntseg ntawm cov khoom siv hluav taws xob, kev ua haujlwm ruaj khov thiab kev ntseeg siab ntawm cov txheej txheem insulating feem ntau yog nyob ntawm qhov nruj thiab kev tswj hwm ntawm cov txheej txheem tsim khoom.A mature production process encompasses raw material pretreatment, precise batching, dispersion and grinding, paint mixing, filtration and quality inspection, and packaging and storage. Txhua kauj ruam yog sib cuam tshuam, ua hauj lwm ua ke los xyuas kom meej lub txheej muaj zoo heev hluav taws xob rwb thaiv tsev, tshav kub tsis kam, thiab ib puag ncig kam rau ua.
Kev tsim khoom pib nrog kev tshuaj xyuas thiab ua ntej ntawm cov khoom siv raw. Resins, curing agents, solvents, fillers, thiab additives yuav tsum tau txheeb xyuas tus kheej rau cov kev qhia tshwj xeeb thiab kev ua tau zoo los xyuas kom meej tias lawv cov purity thiab noo noo cov ntsiab lus raws li kev tsim qauv. Qee cov resins yuav tsum tau ua ntej -solution los yog softening los ntawm cua sov, thaum fillers yuav tsum tau qhuav kom tshem tawm cov dej adsorbed. Hlau oxide pigments qee zaum yuav tsum tau kho saum npoo los txhim kho lawv cov dispersibility thiab compatibility nyob rau hauv cov xim tov. Qhov kev tshuaj xyuas nruj ntawm theem no yog thawj kab ntawm kev tiv thaiv kev taw qhia ntawm impurities thiab kev ua haujlwm sib txawv.
Tom qab ntawd los ntawm batching thiab pib sib tov theem. Qhov hnyav yog ua nyob rau hauv qhov kub thiab txias tsis tu ncua raws li qhov sib piv huab hwm coj teeb tsa hauv kev tsim kom tsis txhob sib xyaw ua txhaum los ntawm ib puag ncig hloov pauv. Kev sib xyaw ua ke feem ntau yog siv cov khoom siv qis- nrawm nrawm los ua ntej fuse cov resin, hnyav, thiab cov khoom ntxiv, tsim kom muaj homogeneous kua theem thiab tsim lub hauv paus zoo rau kev sib cais tom qab. Cov txheej txheem no yuav tsum tau tswj lub nplawm tus nqi thiab lub sij hawm los tiv thaiv ntxov ntxov ntxov ntawm huab cua npuas ntau los yog puas tsuaj rau lub molecular qauv ntawm tej yam rhiab Cheebtsam.
Dispersion thiab kev sib tsoo yog cov kauj ruam tseem ceeb uas txiav txim siab qhov zoo thiab kev tiv thaiv lub zog ntawm cov txheej. Cov kua premixed yog pauv mus rau qhov siab -Speed disperser los yog xuab zeb zeb, thiab pigments thiab functional fillers ntxiv. Lub zog shear quab yuam rhuav tshem cov agglomerates, kom ntseeg tau tias cov khoom sib txawv hauv cov kua xim. Rau cov khoom uas xav tau kev rwb thaiv tsev siab, qhov fineness yuav tsum tau tswj nyob rau hauv ib tug me me ntau yam (xws li, Tsawg tshaj los yog sib npaug zos rau 20μm) kom txo tau pinholes thiab localized tsis muaj zog cov ntsiab lus nyob rau hauv lub txheej. Kev xaiv ntawm kev sib tsoo xov xwm, kev sib hloov ceev, thiab tus naj npawb ntawm cov voj voog yuav tsum tau ua kom zoo raws li cov khoom siv los xyuas kom meej tias ob qho tib si yuav tsum tau ua kom tiav thiab qhov kub thiab txias ntau dhau ua rau cov resin degradation yog zam.
Xim sib tov thiab formulation tshwm sim tom qab dispersion. Nyob rau theem no, cov resin resin, curing tus neeg sawv cev, thiab cov khoom tsim nyog tau ntxiv los kho cov viscosity, leveling zog, thiab cov yam ntxwv kho kom haum rau txoj kev thov thiab cov hom phiaj ua haujlwm. Cov kauj ruam no yuav tsum muaj qhov me me - ntsuas ntsuas kom paub tseeb tias cov txheej txheem hluav taws xob, tiv thaiv tshav kub, thiab adhesion ua tau raws li cov qauv. Kev tswj qhov kub thiab txias yog qhov tseem ceeb ntawm no, vim tias cov tshuaj tiv thaiv ntawm qee cov tshuaj tua kab mob yog qhov kub thiab txias -sensitive; txawm me ntsis sib txawv tuaj yeem cuam tshuam rau kev ruaj khov thiab kho tau.
Lim yog ib kauj ruam tseem ceeb hauv kev tshem tawm cov impurities thiab agglomerate uas tsim tawm thaum lub sijhawm tsim khoom. Siv cov ntxaij lim dej lossis cov cartridges uas tsim nyog qhov pore loj tuaj yeem tshem tawm cov khoom loj thiab cov khoom txawv teb chaws, tiv thaiv txheej txheej tsis xws luag thaum thov. Cov qib pom nyob ntawm cov khoom siv; siab -cov txheej rwb thaiv tsev rau cov khoom siv hluav taws xob feem ntau xav tau ntau- theem pom kom ntseeg tau cov xim purity.
Kev tshuaj xyuas zoo yog ua nyob rau hauv tag nrho cov txheej txheem, nrog rau kev soj ntsuam zoo ntawm cov khoom tiav. Qhov no suav nrog ntsuas ntsuas xws li pom, xim, viscosity, fineness, solids content, drying time, hluav taws xob lub zog, ntim resistivity, thiab kub kuj. Cov qauv tsim nyog tau khaws cia rau yav tom ntej siv los xyuas kom meej batch-rau-batch kev ua tau zoo sib xws. Thaum kawg, cov khoom tiav tau ntim rau hauv qhov chaw tswj hwm nruj kom tiv thaiv cov kuab tshuaj evaporation thiab nqus dej noo, thiab tau sau nrog cov lej batch, hnub tsim khoom, thiab cov xwm txheej khaws cia rau traceability thiab siv kom raug.
Zuag qhia tag nrho, kev tsim cov txheej txheem ntawm cov txheej txheem insulating yog ua raws li kev ntsuas qhov tseeb, nyob rau hauv kev ua kom muaj txiaj ntsig zoo thiab kev sib tsoo, thiab tau lees paub los ntawm kev tswj xyuas nruj, tsim lub kaw- voj voog zoo los ntawm cov khoom siv raw mus rau cov khoom tiav. Tsuas yog los ntawm kev sib koom tes thiab kev tswj xyuas meej ntawm txhua theem tuaj yeem muab cov txheej txheem ruaj khov thiab txhim khu kev qha thiab kev tiv thaiv cov khoom, ua tau raws li qhov yuav tsum tau muaj zog ntxiv ntawm cov khoom siv hluav taws xob, hluav taws xob, thiab hluav taws xob tshiab rau siab -kawg insulating cov ntaub ntawv.
