Kev taw qhia txog peb yam khoom sib txawv rau cov khoom ntim khoom cua sov: POF, PE, thiab PVC
1. PE: Cov yeeb yaj kiab no feem ntau yog siv los qhwv cov khoom hnyav, xws li cov khoom siv kho qhov muag, cov kav dej, thiab txawm tias tag nrho cov fwj ntawm cola. Nws feem ntau tuaj hauv cov raj. Cov qauv tshuaj ntsuam xyuas muaj xws li pob tshab, purity, thiab zaj duab xis uniformity.
2. POF: Qhov no shrink film yog tsim los ntawm compression molding thiab feem ntau tuaj nyob rau hauv lub hnab. Yog tias siv cov raj, qhov kev txiav txim kom muaj nuj nqis yuav tsum yog ob peb tons lossis ntau dua. Txheem xim: Pob tshab. Kev luam ntawv tuaj yeem hloov kho. Cov khoom siv tsuas yog siv rau kev ntim tshuaj, tshuaj pleev ib ce, thiab cov tais diav uas tsis muaj menyuam. Kev soj ntsuam cov qauv: Nws puas qhib thaum lub sij hawm shrinking? Cov ntawv luam puas ploj mus? Pob tshab.
3. PVC: Qhov no shrink film yog tshuab- molded thiab feem ntau tuaj nyob rau hauv yob (nws tseem tuaj yeem ua rau hauv hnab lossis txiav rau hauv ib lub raj raws li cov neeg siv khoom xav tau). Cov xim zoo nkauj yog sapphire xiav thiab lub teeb ntsuab. Thickness feem ntau yog 5 mils. PVC zaj duab xis yog tam sim no cov khoom siv dav siv ntau tshaj plaws. Nws yog pheej yig, muaj qhov kub thiab txias ntau, thiab yuav tsum muaj cua sov me ntsis; thawj qhov chaw tshav kub rau kev ua haujlwm yog cua kub, hluav taws xob infrared, lossis ob qho tib si ua ke. Txawm li cas los xij, PVC yog qhov nyuaj rau kev rov ua dua tshiab, tsim cov pa phem thaum hlawv, thiab tsis zoo ib puag ncig, ua rau nws txwv tsis pub nyob hauv Europe thiab Nyiv. Kev tshuaj xyuas feem ntau suav nrog kev kuaj xyuas: pob tshab, gloss, muaj cov nodules hauv zaj duab xis, thiab zaj duab xis sib xws.
