Raws li cov ntaub ntawv siv hauv kev tsim cov yeeb yaj kiab polyester thiab cov txheej txheem ntau lawm kev faib tawm.

Raws li cov khoom sib txawv thiab cov txheej txheem kev kos duab siv hauv kev tsim cov yeeb yaj kiab polyester tuaj yeem muab faib ua ob hom hauv qab no.

1. Bidirectional Stretch Polyester zaj duab xis (BOPET)

General BOPET zaj duab xis yog siv cov khoom siv lub teeb (tseem hu ua cov khoom siv lub teeb loj, uas yog, cov khoom siv raw polyester nti titanium dioxide cov ntsiab lus ntawm 0.1%, tom qab ziab, melting, extrusion, casting thiab ntsug thiab kab rov tav stretching ntawm qib siab zaj duab xis. , dav siv).BOPET zaj duab xis muaj cov yam ntxwv ntawm lub zog siab, zoo rigidity, pob tshab thiab siab gloss.Tsis muaj ntxhiab, tsis qab, tsis muaj xim, tsis muaj tshuaj lom, zoo heev zog thiab toughness;Nws lub zog tensile yog 3 zaug ntawm PC zaj duab xis, nylon zaj duab xis, cuam tshuam lub zog yog 3 mus rau 5 npaug ntawm BOPP zaj duab xis, muaj kev hnav zoo heev, folding kuj, pinhole kuj thiab tsim kua muag;Lub thermal shrinkage yog me me, ntawm 120 ℃, tsuas yog 1.25% shrinkage tom qab 15min;Nws muaj cov khoom zoo antistatic, yooj yim rau lub tshuab nqus tsev aluminization, thiab tuaj yeem coated nrog PVDC los txhim kho nws cov cua sov sealing, thaiv cov cuab yeej thiab luam ntawv adhesion;BOPET kuj muaj cov cua kub zoo, ua noj ua haus zoo heev, tsis muaj qhov kub thiab txias tsis kam, roj tsis kam thiab tshuaj lom neeg.BOPET zaj duab xis ntxiv rau nitrobenzene, chloroform, benzyl cawv, feem ntau cov tshuaj tsis tuaj yeem ua rau nws yaj.Txawm li cas los xij, BOPET yuav raug eroded los ntawm alkali muaj zog, thiab yuav tsum tau them sai sai rau thaum siv.BOPET zaj duab xis muaj qhov nqus dej tsawg, dej tsis zoo, thiab tsim nyog rau ntim cov khoom noj uas muaj dej ntau.

2. Unidirectional Stretch Polyester Zaj duab xis (CPET)

General CPET zaj duab xis yog siv cov khoom siv semi-matting (cov khoom siv raw polyester chips ntxiv titanium dioxide), tom qab ziab, melting, extrusion, casting thiab longitudinal stretching ntawm zaj duab xis, qib qis tshaj thiab tus nqi hauv polyester zaj duab xis, feem ntau yog siv rau cov tshuaj ntsiav tshuaj. ntim.Vim tias siv tsawg dua, cov tuam txhab tsim khoom tsawg dua, suav txog li 5% ntawm polyester zaj duab xis teb, Suav lag luam kuj tseem tsawg dua, tus qauv thickness ntawm 150μm.
