Dab tsi yog qhov txawv ntawm PVC thiab PVC tawv?
Taw qhia:
Polyvinyl chloride (PVC) yog ntau yam khoom siv dav siv hauv ntau yam lag luam. Nws los ntawm ntau hom, suav nrog PVC thiab tawv PVC. Txawm hais tias lawv yuav zoo li zoo sib xws, muaj qhov sib txawv ntawm ob yam khoom no. Hauv tsab xov xwm no, peb yuav tshawb txog cov yam ntxwv, kev siv, thiab qhov zoo ntawm ob qho tib si PVC thiab tawv PVC, qhia txog lawv qhov sib txawv.
Lus Txhais thiab Txheej Txheem:
PVC:
PVC, tseem hu ua vinyl, yog ib qho hluavtaws thermoplastic polymer muab tau los ntawm vinyl chloride monomers.
