Feem ntau hu ua POLYVINYL CHLORIDE FILM, nws yog ua los ntawmPVC cobthiab lwm yam kev hloov kho los ntawm cov txheej txheem calendering lossis tshuab molding txheej txheem.Qhov dav dav dav yog 0.08 ~ 0.2mm, ntau dua 0.25mm hu ua PVC ntawv.PVC resin ntxiv plasticizer, stabilizer, lubricant thiab lwm yam kev ua haujlwm AIDS, calendering zaj duab xis.

Qhov no zoo ntawm cov zaj duab xis tso cua sov preservation, lub teeb transmittance yog zoo, mos thiab yooj yim rau cov duab, haum rau tsev xog paj, tsev cog khoom thiab me me shed txheej npog cov ntaub ntawv.

Qhov tsis zoo yog: cov yeeb yaj kiab tsis tshua muaj nqi, tus nqi siab;Cov huab cua tsis zoo, tawv thiab nkig ntawm qhov kub thiab txias, yooj yim rau soften thiab xoob ntawm qhov kub thiab txias;Tom qab nag lossis daus ntawm additives, zaj duab xis nto nqus tsev vacuuming, cuam tshuam lub teeb kis tau tus mob;Residual zaj duab xis yog tsis degradable thiab combustion kho.

PVC zaj duab xis tuaj yeem muab faib ua ob pawg, ib qho yog Plasticized PVC Film, tseem hu ua mos PVC zaj duab xis (Plasticized PVC zaj duab xis), lwm qhov tsis yog PVC zaj duab xis, los yog tawv PVC zaj duab xis (Unplasticized PVC Film) Ntawm lawv, PVC nyiaj tsis nruj rau li 2/3 ntawm kev ua lag luam, thiab hloov pauv PVC nyiaj rau 1/3.

mos PVC feem ntau yog siv rau hauv pem teb, qab nthab thiab tawv nto, tab sis vim hais tias mos PVC muaj softener (qhov no kuj yog qhov sib txawv ntawm mos PVC thiab tawv PVC), yooj yim los ua nkig, tsis yooj yim rau txuag, yog li nws siv yog txwv tsis pub. PVC tsis muaj tus neeg sawv cev softening, yog li qhov yooj yim, molding yooj yim, tsis nkig, tsis muaj kuab lom tsis muaj kuab lom, txuag lub sijhawm ntev, yog li kev txhim kho thiab kev siv cov nqi zoo ntawm PVC zaj duab xis yog qhov tseem ceeb ntawm lub tshuab nqus tsev hlwv zaj duab xis, siv rau Txhua yam ntawm cov vaj huam sib luag nto txheej ntawm cov ntim, yog li hu ua cov yeeb yaj kiab zoo nkauj Attach zaj duab xis, siv hauv tsev cov ntaub ntawv ntim tshuaj, thiab ntau lwm yam lag luam Cov khoom siv hauv tsev kev lag luam suav nrog qhov loj tshaj plaws, 60%, ua raws li kev lag luam ntim khoom, muaj ib tug xov tooj ntawm lwm yam me me daim ntawv thov ntawm kev lag luam raws li cov zaj duab xis tsim raw cov ntaub ntawv kev faib tawm: polyethylene zaj duab xis, polypropylene zaj duab xis, PVC zaj duab xis thiab polyester zaj duab xis Raws li cov zaj duab xis siv faib: ua liaj ua teb zaj duab xis (ntawm no raws li cov kev siv ntawm kev ua liaj ua teb zaj duab xis, tau muab faib ua mulching zaj duab xis thiab tsev xog paj zaj duab xis);Ntim zaj duab xis ( ntim zaj duab xis raws li lawv lub hom phiaj tshwj xeeb, thiab tuaj yeem muab faib ua cov ntim khoom noj thiab txhua yam khoom lag luam nrog ntim zaj duab xis, thiab lwm yam) thiab siv rau hauv qhov chaw tshwj xeeb Breathable zaj duab xis nrog tshwj xeeb USES, dej soluble zaj duab xis thiab muaj Kev ua tau zoo ntawm piezoelectric nyias zaj duab xis thiab lwm yam Raws li kev tsim cov txheej txheem ntawm cov yeeb yaj kiab kev faib tawm: extrusion plasticizing Ces tshuab molding ntawm nyias zaj duab xis, hu ua zaj duab xis tshuab;Tom qab extrusion plasticizing, thiab tom qab ntawd cov khoom molten los ntawm cov pwm qhov ncauj ntws extension molding zaj duab xis, hu ua flow extension film;Ib zaj duab xis ua los ntawm cov khoom yas dov los ntawm ob peb lub chais rau ntawm lub calender yog hu ua calendered film.
