Poly (ethylene terephthalate), tseem hu ua PET, yog polyester loj. Nws yog ib copolymer ntawm ethylene glycol thiab terephthalic acid. PET thiab tag nrho lwm cov polyesters yog tsim los ntawm kev hloov pauv cov tshuaj tiv thaiv.
YYuav ua li cas hom polymer yog tus tsiaj?
Polyethylene terephthalate (PET) yog thermoplastic polymer resin ntawm tsev neeg polyester, biodegradable thiab semi-crystalline.
YPuas yog polyethylene terephthalate ib homopolymer lossis copolymer?
Dab tsi yog Hom PET? Polyethylene terephthalate yog muaj ob qho tib si ua homopolymer thiab tseem yog cov khoom lag luam uas tau hloov kho los ntawm copolymer.
Yam khoom twg yog tus tsiaj?
PET, uas sawv cev rau polyethylene terephthalate, yog a daim ntawv ntawm polyester (ib yam li cov khaub ncaws ntaub). Nws yog extruded los yog molded rau hauv lub raj mis yas thiab ntim rau ntim khoom noj thiab dej haus, cov khoom tu tus kheej, thiab ntau lwm yam khoom siv.
PET puas yog ib qho ntxiv polymer?
Polyesters xws li PET (polyethylene terephthalate) yog condensation polymers. Kev tsim ntawm polyester ua raws li cov txheej txheem ib yam li hauv kev sib txuas ntawm cov ester yooj yim. Qhov txawv tsuas yog ob qho tib si cawv thiab cov kua qaub monomer units txhua tus muaj ob pawg ua haujlwm - ib qho ntawm txhua qhov kawg ntawm cov molecule.
