Thaum cov txheej txheem glazing, muaj ntau yam teeb meem tshwm sim. Cov kev ua tsis zoo no tsuas yog xav txog kev tsis zoo ntawm zaj duab xis txheej, thiab qee zaus nws tsis yooj yim rau kev khiav lag luam. Tib yam, tab sis yeej ib txwm nrhiav tau qhov laj thawj ntawm cov ntawv pov thawj ntawm cov ntawv luam tawm, xim kua pleev xim thiab pleev xim, tsis ua haujlwm ntawm glazing thiab cov khoom siv los yog kev sib cuam tshuam. Yog tias koj ua tib zoo saib thiab sojntsuam nws zoo zoo, koj tuaj yeem tsim cov lus txiav txim siab thiab siv sijhawm los txiav txim siab ua haujlwm nrog lawv.
Hom kev ua yuam kev hauv glazing yog:
Ua ntej, streaks los yog wrinkles tshwm nyob rau hauv zaj duab xis saum npoo
Vim li cas thiaj li yog: cov viscosity ntawm qhov txheej txheej glazing yog siab, qhov txheej tsis zoo li tus txheej txheem, thiab cov hlua khau muaj tshwm sim. Raws li qhov sib txawv ntawm qhov teeb meem ntawm cov ntawv luam tawm, qhov xim pleev xim nrog kev sib tw zoo thiab kev sib tsoo yuav raug xaiv tau; los yog tus nqi tsim nyog ntawm thinner tuaj yeem muab ntxiv los txo qhov nqi ntawm tus txheej txheem. Yog tias qhov nyiaj ntau dhau lawm, qhov nyiaj yuav raug txo los ntawm kev kho; qee zaus cov xim muaj xim muaj qhov tsis zoo rau lub plhaub ntim ntawm cov teeb meem, qhov cuam tshuam rau lub plab ntawm cov yeeb yaj kiab tsim, los yog cov cuab yeej ntawm cov xim tsis zoo, thiab cov txheej txheem kev ua haujlwm tsis muaj feem cuam tshuam tus txheej txheem ntawm cov txheej , nws yuav raug siv nrog lwm hom glazing coatings los yog hloov txheej txheem rau kev ua kom haum rau kev ua tiav ntawm cov txheej.
Thib ob, cov luam tawm ib leeg rau ib leeg
Yog vim li cas yog: lub volatility ntawm qhov hnyav hauv cov txheej pleev yog qhov zoo, thiab kev tu kom qhuav ntawm txheej yog cov neeg pluag. Xav txog kev hloov qhov hnyav nrog siab volatilization tus nqi los yog hloov hom glazing txheej; lossis txheej txheej txheej txheej yog tuab heev, qhov hnyav hauv qhov txheej tsis tag volatilized, siab qhov seem, txo cov thickness film; los yog ua haujlwm tsis zoo hauv glazing txheej los yog calendering, lub sij hawm luv qhuav thiab tsis tu kom qhuav ntawm txheej, tuaj yeem txhim kho kev kub ua haujlwm hauv glazing txheej thiab calendering Txo kev ceev thiab ua kom lub tsho kom qhuav.
Thib peb, zaj duab xis thickness ntawm zaj duab xis yog pluag
Yog hais tias nws yog qhov teeb meem zoo ntawm cov saum txheej, nws yuav tsum tau muab xav kom hloov qhov zoo ntawm cov txheej pleev xim raws li cov txheej txheem thiab nyiaj txiag; yog tias qhov txheej no tsis thim, qhov txheej txheem tsis txaus los yog cov txheej txheem lo me me, lub roughness siab, thiab qhov nqus yog qhov muaj zog. Yog hais tias cov nplaum ntawm cov ntawv luam tawm tsis yooj yim, nws yuav tsum tau nce rau hauv cov nqi txheej, ua rau kom cov coating, los yog siv ib qho glazing primer ua ntej ua, thiab tom qab ntawd siv glazing; nws kuj yuav yog glazing thiab ziab. Thaum lub calendering kub tsis muaj, lub siab tsis tshua muaj siab me me, ces cov txheej txheem tsis tas yuav tsum tau kho thaum lub sijhawm ua haujlwm nce siab thiab nce siab; nws kuj yog kwv yees tias cov cuab yeej nws tus kheej yog tshwm sim los, xws li hnav ntawm lub calendered steel sawb, gloss smoothness txo, Nws yog tsim nyog yuav tsum kho thiab txhim kho qhov mob ntawm lub calendered steel strip.
Plaub, tom qab kev khij nyiab, qhov dawb paug ntawm qhov teeb meem tshwm sim muaj lub teeb xim, thiab lub teeb xim muaj qhov sib txawv.
Yog vim li cas ho yog: cov kua roj vanish txheej muaj ib qho kev daws teeb meem ntawm tus number case txheej, uas yog los hloov hom txheej lossis hloov qhov kex; Yog tias tus cwj mem tsis ziab qhuav, qhov xoos ntawm lub plhaub taum plawv tsis zoo, nws yog qhov tsim nyog los txhim kho qhov ziab ntawm tus cwj mem, tom qab tus cwj mem qhuav ziab. Tom qab ntawd, qhov txheej txheem yog siv los txo cov nqi hnyav uas ua kom lub plhaub tiab hauv cov khoom ci; Yog hais tias txheej txheej tsis qhuav kiag, thiab qhov seem hauv seem hauv txheej txheej txheej siab, lub ziab khaub ncaws kom sov thaum lub caij cov txheej txheem los yog lub tshuab qis dua. Ceev, ntev lub sij hawm kom qhuav thiab txo qhov hnyav residue hauv cov txheej.
Thib tsib, cov txheej yog tsis ncaj, muaj npuas, sib tw, thiab lwm yam.
Yog vim li cas: qhov kub nro nqi ntawm qhov txheej txheej glazing yog loj, thiab cov nyhuv ntxhib ntawm tus number case txheej rau ntawm qhov teeb meem luam tawm tsis zoo. Qhov nqi nro yuav tsum raug txo kom zoo rau cov khoom ntub ntawm cov txheej xim ntawm tus number case txheej; qhov hnyav hauv cov txheej no tsis zoo, thiab txheej txheej hauv. Cov kua tshuaj yog qhov siab, thiab qhov hnyav nrog qhov siab hloov siab tuaj yeem hloov tau los yog lub tsho tseem yuav tau qhuav thiab khoov tom qab. Nws tseem ua tau tias qhov ceev ntawm lub txheej yog ceev heev, qhov ziab tshua zis yog tsawg, cov txheej tsis qhuav huv, thiab qhov hnyav yog volatilized. Ua tiav, cov txheej txheem ntawm glazing txheej yuav tsum raug kho; tus number case txheej nyob rau saum npoo ntawm cov teeb meem luam tawm kuj tseem siv tau. Qhov no yuav tsum ua kom zoo, xws li tshem cov roj zoo ntawm cov nplais ntawm cov xuab zeb crystallized los yog ua qhov kev kho mob kom zoo dua qub. Wetting ntawm tus number case txheej los txo los yog tshem tawm cov teebmeem ntawm crystallization ntawm tus number case txheej rau glazing txheej.
Rau, ua yeeb yaj kiab nto foaming
Yog vim li cas: Thaum lub sijhawm calendering, lub siab loj dhau, qhov kub ntawm lub calendered steel sawb yog siab dhau lawm, thiab txheej txheej txheej txheej yog ib feem softened, uas xav tau kom tsim nyog txo qhov siab thiab qhov kub ntawm cov calendering; nws kuj yuav yog qhov txheej txheem ci thiab txheej txheem kom zoo nkauj. Txuas ntoo txuam, yog li ntawd tom qab lo txheej txheej saum npoo ntawm qhov teeb meem luam tawm txias, cov qoob loo ntawm tib lub teeb nraub qis tsis zoo, thiab tus txheej txheem ntawm kev xav tau hloov mus ua kom zoo li cov xim pleev, , thiab cov txheej txheej zoo tuaj ntawm qhov sib txig sib txig. Peel quab yuam.
Xya, hauv calendering, lub adhesion ntawm qhov teeb meem luam tawm thiab daim kab xev cov ntaub nplaum yog pluag.
Yog vim li cas thiaj li: qhov txheej yog ib yam nkaus, nyias yuav tsum tau nyiaj; qhov viscosity ntawm txheej yog tsawg tsawg, thiab tus nqi ntawm cov xim yuav tsum tau nce; ces lub siab ntawm lub calendering yog tsawg heev, calendering kub tsis txaus, thiab calendering kub yog nce, thiab lub siab yog nce. Lub teeb siab.
Yim, tom qab daim ntawv sau cia, daim nplaum yog yooj yim tawg.
Yog vim li cas ho yog: qhov kub thiab txias tshaj plaws, yog li ntawd cov ntawv luam tawm tau dej ntau dhau hauv lub calendering, cov ntsiab lus dej txo kom tsawg, yog li cov ntaub ntawv cov kua qaub ncaug, qhov kub ua hauj lwm hauv calendering yuav tsum qis, thiab cov kev ntsuas zoo yog coj los tuav lub ntsiab lus ntawm cov dej hauv cov ntawv luam tawm; Nyob hauv cov calendering, lub siab loj heev, kom lub elongation thiab yas ntawm cov teeb meem luam tawm raug txo, lub toughness yog deteriorated, thiab lub siab hauv calendering yuav txo; Yog hais tias tus txheej txheem tom qab tsim nyog ntawm cov xim pleev xim tsis zoo, txoj kev ua tiav tom qab tsim nyog yuav tsum rov xaiv. Qhov ci txheej; cov txheej txheem tom qab tsis tau xaiv, thiab cov txheej txheem tom qab ua haujlwm tau raug kho kom haum raws li qhov kev pom zoo ntawm cov ntawv luam tawm tom qab kuaj xyuas.
Cuaj hlis, qhov ci ntsa iab ntawm ob sab tom qab kev khwv nyiaj txiag tsis sib haum
Yog vim li cas thiaj li: nyob hauv lub calendering, qhov siab ntawm ob sab ntawm qhov siv yeeb ncuab tsis sib npaug, lossis hnav rau ob tog ntawm qhov siv yeeb nkab yog inconsistent. Lub siab ntawm ob tog ntawm txoj siv glazing yuav tsum muab kho kom sib npaug zos, thiab qhov kev sib tshooj ntawm tus neeg tshav kub kub thiab cov kev sib tshuam uas siv tau yuav tsum muab kho dua. Qhov siv ntaub nplaum yog siv nruj nrawm nrawm rau sab ob sab thiab hnav ris tsho npo; nws kuj yuav tsis sib npaug ntawm ob sab ntawm cov txheej txheem glazing. Nws yog ib qho tsim nyog yuav tau kho cov txheej txheem thaiv hniav ntawm lub tshuab kom pom cov kev sib koom tes thiab qhov kev sib txuas ntawm cov menyuam uas muaj peev xwm thiab cov menyuam uas muaj txheej txheem. Lub thickness ntawm lub txheej on ob sab yog ua tsis tau zoo li sai tau.
