Cov khoom siv yooj yim ntawm lub thawv ntim khoom PET:
PET yog ib hom polymer dawb mis nyuj los yog daj daj uas muaj cov khoom siv crystalline ntau heev nrog rau qhov chaw du thiab ci ntsa iab. Kev ruaj khov zoo, kev hnav me me thiab kev tawv siab, nrog rau qhov tawv tshaj plaws ntawm cov thermoplastics: kev ua haujlwm rwb thaiv hluav taws xob zoo, tsis cuam tshuam los ntawm qhov kub thiab txias. Tsis muaj tshuaj lom, tiv taus huab cua, nqus dej tsawg.
Qhov zoo ntawm lub thawv ntim khoom PET:
1. Muaj cov khoom siv kho tshuab zoo, lub zog cuam tshuam yog 3 ~ 5 zaug ntawm lwm cov yeeb yaj kiab, kev tiv thaiv zoo;
2. Nrog rau qhov kub thiab txias zoo heev, nws tuaj yeem siv tau ntev hauv qhov kub thiab txias ntawm 120 ℃.
Kev siv luv luv tuaj yeem tiv taus 150 ℃ kub siab, tuaj yeem tiv taus -70 ℃ kub qis, thiab qhov kub siab thiab qis tsis muaj qhov cuam tshuam rau nws cov khoom siv kho tshuab;
4. Cov pa roj thiab dej tsis nkag tau yooj yim, thiab tiv taus roj, dej, roj thiab ntxhiab tsw zoo heev;
5. Muaj pob tshab siab, tuaj yeem thaiv lub teeb ultraviolet, ci ntsa iab zoo;
6. Tsis muaj tshuaj lom, tsis muaj saj, kev noj qab haus huv zoo thiab kev nyab xeeb, tuaj yeem siv ncaj qha rau kev ntim khoom noj.
PET siv dav hauv cov fiber, zaj duab xis thiab cov yas engineering. PET fibers feem ntau yog siv hauv kev lag luam textile. PET zaj duab xis feem ntau yog siv rau hauv cov ntaub ntawv rwb thaiv tsev hluav taws xob, xws li capacitors, cable rwb thaiv tsev, printed circuit wiring substrate, electrode groove rwb thaiv tsev thiab lwm yam. Lwm qhov chaw siv ntawm PET zaj duab xis yog wafer puag thiab band, xws li zaj duab xis yeeb yaj kiab, X-ray zaj duab xis, daim kab xev suab, daim kab xev computer hluav taws xob, thiab lwm yam. PET zaj duab xis kuj tseem siv los nqus cov txhuas mus rau hauv cov zaj duab xis metallized, xws li kub thiab nyiaj hlau, micro capacitor zaj duab xis, thiab lwm yam. Daim ntawv zaj duab xis siv tau rau txhua yam khoom noj, tshuaj, cov khoom ntim khoom tsis muaj tshuaj lom. Iav fiber reinforced PET yog tsim rau kev lag luam hluav taws xob thiab hluav taws xob thiab tsheb, siv rau hauv ntau yam coil skeleton, transformer, TV, recorder qhov chaw thiab plhaub, lub teeb tuav tsheb, lub teeb, lub teeb dawb kub tuav, relays, lub hnub ci rectifier, thiab lwm yam.
Cov thawv PET yog ib qho kev xaiv zoo heev. Hauv lub neej txhua hnub, muaj kev xav tau ntau rau kev siv cov thawv ntim PET. Ntau lub chaw tsim khoom thiab cov neeg siv khoom yuav siv cov thawv ntim PET hauv kev ua thiab kev tsim khoom, thiab qhov kev xav tau rau cov thawv ntim PET hauv lub neej txhua hnub yog siab heev. Cov qauv yooj yim thiab daim ntawv thov ntawm lub thawv ntim PET saum toj no.
