Daim ntawv thov dav ntawm Tshuaj PVC / PVDC

Kws Ntim Ntim PVC /PVDC Txheej txheem cej luam:

PVC Cov Tshuaj Siv Tshuaj PVC feem ntau yog ua los ntawm polyvinyl chloride (PVC) cob nrog qee yam kev pab, los ntawm extrusion, calendering, thiab lwm txoj kev ua los tsim cov khoom siv ntim khoom tshiab uas ua tau raws li qhov yuav tsum tau siv tshuaj ntsuab. Nws cais txhua lub ntsiav tshuaj, lub tshuaj, thiab capsule ywj pheej los ua nws cov chav ntim khoom me tshaj plaws, uas zoo heev txhim kho qhov tseeb thiab kev nyab xeeb ntawm cov khoom lag luam kws tshuaj.

PVDC cov khoom tuaj yeem muab coated ntawm PVC zaj duab xis rau cov dej noo heev thiab cov pa oxygen cov khoom, nyob ntawm qhov hnyav. PVDC coated cov yeeb yaj kiab cov yeeb yaj kiab yog cov yeeb yaj kiab uas muaj teeb meem tshaj plaws thiab cov yeeb yaj kiab uas siv rau cov tshuaj hlwv ntim. PVDC Txheej Txheej Tseem tseem muaj kev lag luam ntau tshaj plaws ntxiv rau cov dej thiab cov pa tiv thaiv mus rau PVC cov yeeb yaj kiab.

Kev tsim kho ntxiv ntawm cov ntaub ntawv ntim ntim ntaub ntawv

Tom qab nkag mus rau xyoo 1990, kev nyab xeeb ntawm kev kho mob tau txais ntau thiab ntau xim. Vim tias cov khoom xyaw ntawm qee cov tshuaj muaj kev cuam tshuam nrog duminescence thiab oxidation, Lub ntsej muag pvc txhuas-yas ntim tsis tuaj yeem ua kom tau raws li cov ntim khoom uas yuav tsum muaj. Lub sijhawm no, tus r&D cov neeg ua haujlwm tau ua tiav daim ntawv PVC cov tshuaj ntsuab ua cov khoom siv hauv paus thiab ntxiv qee cov ntaub ntawv loj polymer (PVDC), uas ua ke rigidity ntawm PVC, Moulding zoo, thiab PVDC ntau cov ntxhiab tsw rau dej vapor, oxygen, Thiab CO2. Nws muaj cov khoom siv zoo heev thiab ua cov khoom siv tshiab uas tuaj yeem ua tau kom tau raws li cov tshuaj yuav tsum tau ntawm cov tshuaj kho mob deliquescent thiab yooj yim, thiab qee cov tshuaj hauv Suav los khaws cov tshuaj tsw qab.

Kev thov dav dav ntawm cov kws tshuaj PVC

Tib lub sijhawm, nws tseem siv lub ptt ptt aluminium-yas ntim hom, thiab cov khoom ntim cov khoom thiab cov thev naus laus zis yog qhov zoo ib yam li cov ntaub ntawv ntim rau PVC. Cov series no ntawm cov khoom siv tau tuaj yeem kho cov ntaub ntawv ntim rau lub Hoobkas raws li kev ua tau zoo ntawm kev ya raws thiab oxidation ntawm cov tshuaj, thiab dhau los ua qib siab dua ptp ntim khoom ntim. Ntxiv rau, Muaj PVC / PE Ntim Khoom Siv Hloov Cov iav kom ntim cov kua thiab cov tshuaj pom, uas txhim kho kev nyab xeeb ntawm cov tshuaj no.

Txoj kev loj hlob sai ntawm cov tshuaj PVDC qhwv

Raws li cov khoom lag luam tshwj xeeb, Cov tshuaj muaj txiaj ntsig nce ntxiv ntawm kev ntim. Lub cev tshwj xeeb ntawm PVDC txheej tau nyiam ntau thiab ntau xim, thiab tau siv nyob rau hauv cov ntaub ntawv ntim khoom. Cov khoom tshwj xeeb rau lub cev tshwj xeeb no suav nrog kev thaiv zoo thiab tshuaj ruaj khov rau oxygen, Dej Vapor, carbon dioxide, thiab organic tebchaw. Raws li ntau thiab ntau cov ntaub ntawv polymer tau ua rau ntim ntawm cov chaw muag tshuaj, Qhov tsuas yog pvdc chloride muaj cov teeb meem loj rau cov dej vapor thiab oxygen tib lub sijhawm. Qhov tseeb, Ntau cov ntaub ntawv polymer muaj cov teeb meem loj ntawm cov dej vapor, thiab ib txheej nyias nyias ntawm PVDC rau lawv yuav zoo heev txhim kho qhov kev ua tau zoo no. Ntxiv rau, Lub PVDC txheej tuaj yeem thaiv cov pa oxygen thiab lwm yam tshuaj ntsuab.High zoo ntsiav tshuaj yuav ntim tau PVC / PVDC zaj duab xis yuav nrov dua.

PVC-PVDC Zaj Duab Xis Tshuaj

PVDC Plastique kuj tseem muaj cov khoom ntawm acidractance, alkali tsis kam, roj hlawv, hnyav tiv thaiv, thiab tshuaj tiv thaiv, ua kom nws haum ntau rau ntau yam ntim cov chaw muag tshuaj, Tshwj xeeb tshaj yog cov uas nquag ua rau Deliquescent, nquag mus rau oxidation, lossis muaj cov tshuaj siv tshuaj thiab yuav tsum muaj kev tiv thaiv. Ntim rau cov tshuaj uas hnov ​​tsw lossis thaiv qhov nqus ntawm peculiar tsw.
