PVC piv txwv li Poly vinyl chloride yog homopolymer raws li nws tau tsim los ntawm ib hom monomer piv txwv li vinyl chloride. Cov polymers uas nws rov ua dua yog muab los ntawm ob hom monomers hu ua copolymers . Piv txwv li, Buna-S yog a copolymer ntawm 1,3-butadiene thiab styrene.

Ib yam nkaus, puas yog polyvinyl chloride yog copolymer?

Polyvinyl tshuaj dawb Acetate (PVCA) yog cov thermoplastic copolymer ntawm vinyl tshuaj dawb thiab vinyl acetate. Nws yog siv nyob rau hauv kev tsim hluav taws xob rwb thaiv tsev, ntawm kev tiv thaiv npog (nrog rau cov tsoos tsho), thiab ntawm credit cards thiab swipe cards.

Ib tug kuj yuav nug, dab tsi yog copolymer yas? A copolymer yog a yas cov khoom tsim los ntawm copolymerization ntawm ob lossis ntau qhov sib txawv monomers. Piv txwv li, ABS yog tsim los ntawm acrylonitrile, butadiene, thiab styrene molecules. Copolymers ua ke cov khoom ntawm lawv cov khoom sib xyaw rau kev txhim kho kev ua haujlwm, ua haujlwm ntev, thiab lwm yam.

Tom qab ntawd, hom polymer twg yog PVC?

Polyvinyl tshuaj dawb . Polyvinyl tshuaj dawb ( PVC ), ib tug hluavtaws cob ua los ntawm cov polymerization ntawm vinyl chloride.

Puas yog PVC yog yas thermosetting?

Cov yas tuaj yeem raug cais raws li ib qho thermosetting los yog thermoplastic. Polyvinyl tshuaj dawb ( PVC ) yog suav tias yog thermoplastic. Hauv kev sib piv, thermosetting polymers tsim irreversible tshuaj bonds raws li lawv kho thiab yog li ntawd lawv tawg thaum rhuab thiab yuav tsis rov ua dua li qhov kub thiab txias.
