POLYVINYL chloride zaj duab xis, yog ua los ntawmPVC cobthiab lwm yam kev hloov kho los ntawm cov txheej txheem calendering lossis tshuab molding txheej txheem.Qhov dav dav yog 0.08 ~ 0.2mm, ntau dua 0.25mm hu ua PVC ntawv.Plasticizer, stabilizer, lubricant thiab lwm yam kev ua haujlwm AIDS yog ntxiv rau PVC resin, thiab zaj duab xis yog tsim los ntawm calendering.
PVC zaj duab xis tuaj yeem muab faib ua ob pawg, ib qho yog Plasticized PVC Zaj duab xis, tseem hu ua mos PVC Zaj duab xis, lwm qhov yog Unplasticized PVC Film, tseem hu ua tawv PVC zaj duab xis.
Ntawm lawv, nyuaj PVC nyiaj txog li 2/3 ntawm kev ua lag luam, thiab muag 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 khaws cia, yog li nws ntau yam kev siv yog txwv. .Hard PVC tsis muaj softener, yog li nws muaj qhov yooj yooj yim, yooj yim molding, tsis yooj yim rau nkig, tsis muaj tshuaj lom thiab tsis muaj kuab paug, lub sijhawm khaws cia ntev, yog li nws muaj kev txhim kho zoo thiab daim ntawv thov nqi.Lub ntsiab ntawm PVC zaj duab xis yog lub tshuab nqus tsev hlwv zaj duab xis, siv rau saum npoo ntim ntawm txhua yam ntawm cov vaj huam sib luag, yog li nws tseem hu ua zaj duab xis zoo nkauj, nplaum zaj duab xis, siv hauv cov khoom siv hauv tsev, ntim khoom, tshuaj thiab ntau lwm yam lag luam.Ntawm lawv, kev lag luam khoom siv hauv tsev suav nrog qhov loj tshaj plaws ntawm 60%, ua raws li kev lag luam ntim khoom, muaj ntau lwm yam kev siv me me ntawm kev lag luam.
⑴ Raws li cov khoom siv raw khoom siv rau kev tsim zaj duab xis: polyethylene zaj duab xis, polypropylene zaj duab xis, polyvinyl chloride zaj duab xis thiab polyester zaj duab xis.
(2) Kev faib tawm los ntawm kev siv zaj duab xis: zaj duab xis ua liaj ua teb (ntawm no raws li kev siv cov yeeb yaj kiab ua liaj ua teb, tuaj yeem muab faib ua zaj duab xis yas thiab zaj duab xis tsev cog khoom);Ntim zaj duab xis (PACKAGING zaj duab xis raws li nws cov kev siv tshwj xeeb, thiab tuaj yeem muab faib ua cov ntim khoom noj thiab ntau yam khoom lag luam ntim zaj duab xis, thiab lwm yam) thiab rau ib puag ncig tshwj xeeb, nrog rau kev siv tshwj xeeb ntawm breathable zaj duab xis, dej soluble zaj duab xis thiab piezoelectric zog ntawm zaj duab xis. .
(3) Raws li cov yeeb yaj kiab molding kev faib tawm: extrusion plasticization, thiab tom qab ntawd tshuab moulding zaj duab xis, hu ua tshuab moulding zaj duab xis;Tom qab extrusion plasticization, thiab tom qab ntawd cov khoom molten ntws los ntawm pwm lub qhov ncauj ua zaj duab xis, hu ua flow film;Nyob rau hauv lub tshuab calendering los ntawm ob peb yob dov plasticizing cov ntaub ntawv ua los ntawm zaj duab xis, hu ua calendering zaj duab xis.
Kev siv ntawm PVC zaj duab xis
PVC cov khoom siv kho kom zoo nkauj: Nws kuj muaj cov khoom tiv thaiv kev laus thiab cov dej ntws, lub teeb kis tau zoo thiab kev txuag hluav taws xob, tsis muaj dej tsis kam rau 4 mus rau 6 lub hlis thiab lub neej kev nyab xeeb ntawm 12 txog 18 lub hlis.Nws yog dav siv los ua cov khoom siv tau zoo tshaj plaws thiab txuag hluav taws xob rau hnub ci tsev cog khoom.
PVC kuj tseem tuaj yeem ua cov yeeb yaj kiab yas, ntxiv qee qhov ntawm cov khoom siv tuaj yeem tsim ntau yam xim sib txawv ntawm cov yeeb yaj kiab.
PVC FOIL: yas, hlau, pob tshab zaj duab xis, tsis yog ntawv ntim, ntim yas, ntim ntoo, ntim hlau, thiab lwm yam.
