Cov yam ntxwv ntawm cov khoom polyester muaj xws li lub zog zoo thiab corrosion kuj, siab melting point thiab kub deformation kub, yooj yim noo noo nqus nyob rau hauv lub molten lub xeev, thiab ntau yam kev siv.
Polyester, raws li cov thermoplastic feem ntau, muaj lub zog zoo thiab corrosion kuj. Nws muaj lub siab melting point thiab kub deformation kub, uas txhais tau hais tias yuav tsum tau kub thiab siab zog ntau dua nyob rau hauv kev txhaj tshuaj molding. Tsis tas li ntawd, polyester yooj yim absorbs noo noo nyob rau hauv lub molten lub xeev, yog li nws yuav tsum tau them sai sai mus rau noo noo-pov thawj thiab qhuav kev kho mob thaum lub sij hawm ua kom tsis txhob npuas thiab discoloration. Cov yam ntxwv no ua rau cov khoom siv polyester kom muaj kev ruaj ntseg hauv ntau qhov chaw thiab tsim nyog rau kev tsim cov khoom lag luam uas yuav tsum tau ua kom muaj cua sov thiab tiv thaiv corrosion.
Polyester muaj ntau yam kev siv, suav nrog fibers, films, thiab cov khoom yas. Hauv kev lag luam xws li textile thiab khaub ncaws tsim, polyester fibers (tseem hu ua polyester) yog dav siv rau lawv zoo wrinkle tsis kam, zoo tuav, siab zog, thiab elastic rov qab. Cov yam ntxwv no ua rau cov ntaub ua los ntawm polyester fibers tsis yog tsuas yog muaj zog thiab ruaj khov, tab sis kuj tuaj yeem rov qab sai sai rau lawv cov qauv qub thiab tswj kom zoo zoo. Tsis tas li ntawd, polyester fiber tseem tiv taus hnav thiab tsim kua muag thiab tsis lo rau cov plaub hau, uas ua rau muaj kev yooj yim thiab kev nplij siab rau lub neej txhua hnub12.
