Xiongxing Group daws qhov dawb frosting ntawm PVC calendered zaj duab xis li cas

Kev tsom xam thiab kev daws ntawm Dawb Frosting ntawm PVC Calendering Film

Tam sim no, cov txheej txheem PVC calendering tseem yog cov txheej txheem siv dav tshaj plaws thiab kev lag luam hauv kev tsim cov yeeb yaj kiab, thiab cov kev tsim kho tshiab kawg hauv daim teb no tau txuas ntxiv mus rau lwm qhov chaw thov. Ntau yam PVC zaj duab xis tseem yog cov khoom lag luam nrov tshaj plaws, xws li pob tshab yas zaj duab xis, cua tshuab zaj duab xis, lub teeb lub thawv zaj duab xis, pas dej ua ke zaj duab xis, ob-sided glossy zaj duab xis, advertising inkjet zaj duab xis thiab lwm yam. Nws tuaj yeem pom tias daim ntawv thov ntawm PVC calendered zaj duab xis yog dav heev, thiab kev lag luam xav tau kuj loj heev.

Nyob rau hauv cov txheej txheem ntawm PVC calendered zaj duab xis, qhov tshwm sim ntawm nag lossis daus qee zaum tshwm sim, uas yog, txheej ntawm "dawb Frost" yog tsim rau saum npoo ntawm zaj duab xis los yog ntawm cov calendering roller (los yog traction roller), uas yuav cuam tshuam rau kev siv. ntawm cov yeeb yaj kiab lossis txawm tias raug muab pov tseg hauv qhov xwm txheej hnyav (xws li cov yeeb yaj kiab hauv pas dej ua ke). Ink absorption ntawm lub teeb lub thawv zaj duab xis vim los nag lossis daus). Los ntawm qhov kev pom, cov ntaub ntawv precipitated feem ntau yog lubricants, hmoov stabilizers thiab calcium carbonate. Cia peb txheeb xyuas lub luag haujlwm ntawm peb cov ntaub ntawv precipitated hauv kev tsim cov yeeb yaj kiab PVC calendered.

Thawj lub roj nplua nyeem tuaj yeem ua rau saum npoo ntawm cov khoom du thiab zoo nkauj thaum lub sijhawm tsim cov PVC calendered zaj duab xis, thiab tib lub sijhawm, nws tuaj yeem txhim kho cov dej ntws ntawm cov yas yaj thiab txo thiab tsis txhob muaj kev sib txhuam ntawm cov khoom siv. Txawm li cas los xij, thaum siv cov roj nplua nyeem tsis raug thiab tshaj nws cov kev txwv tsis pub dhau, nws yooj yim los nag rau saum npoo ntawm cov khoom, uas feem ntau hu ua "blooming", uas cuam tshuam rau cov tsos ntawm cov khoom thiab tseem cuam tshuam rau nws cov cwj mem nqus.

Qhov thib ob siv cov stabilizers yog tias PVC yuav dhau los ntawm thermal degradation vim qhov kub thiab txias thaum ua haujlwm. Txhawm rau txhim kho nws txoj kev ruaj ntseg, stabilizers yuav tsum tau ntxiv thaum ua. Ntau cov stabilizers tsis tsuas yog muaj cov nyhuv stabilizing, tab sis kuj muaj cov nyhuv lubricating ib nrab. Qhov tsis zoo sib xws ntawm cov stabilizer kuj yuav ua rau "tej" thiab tsiv teb tsaws.

Qhov thib peb yog calcium carbonate raws li ib tug muab tub lim. Ntxiv qhov tsim nyog ntawm calcium carbonate muab tub lim tuaj yeem txo qhov molding shrinkage tus nqi ntawm cov yas thiab txhim kho nws cov cua sov, nplaim hluav taws thiab lub zog. Lwm qhov laj thawj tseem ceeb ntawm kev ntxiv calcium carbonate yog txo cov nqi thiab txo cov nqi ntawm PVC resin. Txawm li cas los xij, calcium carbonate muaj qhov teeb meem ntawm cov kua qaub thiab tsis ruaj khov vim nws cov khoom siv tshuaj lom neeg, thiab yog tias qhov sib ntxiv tsis tau tswj tau zoo, nws yuav ua rau nag lossis daus los ntawm cov yeeb yaj kiab.

Saum toj no, peb tau soj ntsuam cov laj thawj los ntawm peb yam ntawm "dawb Frost" ntawm PVC calendered zaj duab xis precipitate. Nws zoo nkaus li tias muaj ntau yam cuam tshuam, thiab muaj ntau yam kev sib txuas. Txhawm rau txheeb xyuas thiab daws qhov teeb meem no, nws yeej ua rau cov yas ntau heev Cov neeg hauv kev lag luam tsim khoom tau ua haujlwm hnyav. Yog tias muaj cov khoom siv uas tuaj yeem ua tsis tau tsuas yog ua tus muab tub lim, tab sis kuj ua lub luag haujlwm lubricating, thiab tseem tuaj yeem ua kom ruaj khov ntawm cov txheej txheem PVC, qhov teeb meem no puas tuaj yeem daws tau?

Cov khoom no yeej muaj tiag. Nws yog Xiongxing tus cim tus cwj mem-kho tus neeg sawv cev. Nws tau raug siv los ua cov hmoov ua haujlwm tshiab rau PVC calendering zaj duab xis. Nws tseem tuaj yeem siv los ua cov hmoov yas yas, uas ncaj qha txo cov nqi ntau rau PVC cov tuam txhab. , thiab tuaj yeem daws qhov teeb meem ntawm "dawb Frost" ntawm PVC calendered zaj duab xis.

Qhov tshwj xeeb tus cwj mem-kho tus neeg sawv cev no muaj qhov zoo ruaj khov thiab zoo sib xws nrog PVC cob. Nws tuaj yeem ua tau raws li qhov dav ntawm cov txheej txheem ntau lawm, thiab tsim nyog rau kev siv ntau yam khoom siv mis. Nyob rau tib lub sijhawm, nws ua tau raws li qhov yuav tsum tau muaj ntawm kev tiv thaiv ib puag ncig hauv tsev thiab txawv teb chaws thiab kev nyab xeeb siv cov qauv. Tus cwj mem kho tus neeg sawv cev nws tus kheej yog ib hom tshiab ntawm cov khoom siv tsis muaj hlau tsis muaj hlau, uas tsis muaj cov hlau hnyav, thiab nws cov kua qaub thiab alkali kuj muaj zog dua li ntawm calcium carbonate. Nws cov yellowing kuj tuaj yeem txhim kho qhov zoo ntawm zaj duab xis. Tsis tas li ntawd, nws kuj muaj cov khoom ntim siab, txo cov nqi ntawm cov khoom kim heev, tuaj yeem txhim kho qhov nro ntawm zaj duab xis, ua rau cov yeeb yaj kiab du thiab tsis lo, thiab ua lub luag haujlwm lubricating. Thaum kawg, lwm txoj haujlwm tshwj xeeb ntawm tus cwj mem-kho tus neeg sawv cev yog qhov muaj peev xwm kho tus cwj mem muaj zog, uas tuaj yeem txhim kho tus cwj mem adhesion, thiab tus number case ruaj ruaj tsis txav los yog yaj tus number case, uas daws cov teeb meem kev lag luam, uas kuj tso cai rau nws ua. siv nyob rau hauv sab nraum zoov advertising films.
