1, polyester zaj duab xis qhia

Polyester zaj duab xis kuj hu ua polyester zaj duab xis (PET) (lub teeb zaj duab xis, polyester zaj duab xis, rhiab ntawv, polyester zaj duab xis, benzene tin zaj duab xis, cellophane, tso zaj duab xis), yog ib tug polyethylene terephthalate raws li raw cov ntaub ntawv, kev siv ntawm extrusion txoj kev rau hauv tuab zaj duab xis, thiab tom qab ntawd bidirectional stretching ua los ntawm cov khoom siv zaj duab xis.

Polyester zaj duab xis (polyester zaj duab xis, ib puag ncig tiv thaiv zaj duab xis, PET zaj duab xis, opal zaj duab xis thiab lwm yam luam ntawv thiab ntim consumables), dav siv nyob rau hauv iav fiber reinforced yas kev lag luam, tsev ntaub ntawv kev lag luam, luam ntawv kev lag luam, tshuaj thiab kev noj qab haus huv.

Tam sim no, Tuam Tshoj tau ntse tsim PET twist zaj duab xis, uas tsis yog-tshuaj lom, tsis muaj xim, pob tshab, ya raws-resistant, breathable, mos, muaj zog, acid-alkali roj thiab hnyav resistant, thiab tsis ntshai ntawm qhov kub thiab txias.Yog cov khoom tsis muaj tshuaj lom, pob tshab siv dua tshiab, feem ntau yog siv hauv ntau hom dej haus, dej ntxhia thiab zaj duab xis ntim, yog tam sim no siv dav hauv ntiaj teb ib qho ntawm cov khoom ntim.

Mylar zaj duab xis yog ib hom polymer yas zaj duab xis, vim nws cov khoom zoo heev thiab ntau thiab ntau nyiam los ntawm cov neeg siv khoom feem ntau.Raws li Tuam Tshoj txoj kev tsim khoom thiab kev ua haujlwm qib tseem tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev ua lag luam, qee qhov tseem yuav tsum tau cia siab rau kev xa khoom.

2, polyester zaj duab xis zog

PET yog ib hom polymer siab, uas ua rau lub cev qhuav dej ntawm ethylene terephthalate.Glycol terephthalate yog tau los ntawm esterification ntawm terephthalic acid thiab glycol.PET yog mis nyuj dawb los yog lub teeb daj, crystalline polymer nrog ib tug du, ci ntsa iab.

PET muaj cov khoom zoo heev (kub kub, tshuaj tiv thaiv).Lub zog thiab toughness, hluav taws xob rwb thaiv tsev, kev nyab xeeb, thiab lwm yam), pheej yig, yog li dav siv fiber ntau, zaj duab xis, engineering yas, polyester fwj thiab lwm yam.

PET muaj cov khoom zoo ntawm lub cev thiab cov khoom siv hauv ntau qhov kub thiab txias, siv sijhawm ntev txog li 120 ℃, rwb thaiv tsev hluav taws xob zoo heev, txawm tias qhov kub thiab txias ntau zaus, nws cov khoom siv hluav taws xob tseem zoo, tab sis tsis zoo corona tsis kam, tiv thaiv tshuaj lom. , huab cua tsis kam, tshuaj tiv thaiv stability, creep, qaug zog tsis kam, kev sib txhuam tsis kam, seem stability zoo heev.Kev nqus dej tsawg, ua rau cov kua qaub tsis muaj zog thiab cov kuab tshuaj organic, tab sis tsis kub resistant rau dej raus dej, tsis alkali tsis kam.

Feem ntau PET yog xim tsis muaj pob tshab, glossy zaj duab xis (cov khoom siv ntxiv tuaj yeem ua rau nws muaj xim), zoo heev txhua yam khoom, siab rigidity, hardness thiab toughness, puncture kuj, kev sib txhuam tsis kam, kub thiab kub tsis kam, tshuaj tsis kam, roj. kev tiv thaiv, huab cua nruj thiab tshuaj tsw qab khaws cia, yog ib qho ntawm feem ntau siv los tiv thaiv kev sib xyaw ua ke zaj duab xis substrates, tab sis corona kuj tsis zoo.
