Cov khoom siv tseem ceeb rau PVC yog muab los ntawm ntsev thiab roj. Lub electrolysis ntawm cov dej ntsev tsim cov tshuaj chlorine, uas yog ua ke nrog ethylene (tau los ntawm cov roj) los ua vinyl chloride monomer (VCM).
polyvinyl chloride nyob qhov twg?
Ntau xyoo dhau los, Polyvinyl Chloride (PVC) yas, feem ntau hu ua "vinyl," tau dhau los ua ib hom yas siv ntau tshaj plaws. Peb pom nws nyob ib puag ncig peb: hauv ntim khoom, khoom vaj khoom tsev, khoom ua si menyuam yaus, khoom siv tsheb, khoom siv hauv tsev, khoom siv hauv tsev kho mob, thiab ntau pua yam khoom
polyvinyl chloride yog dab tsi?
Lub electrolysis ntawm cov dej ntsev tsim cov tshuaj chlorine. Cov tshuaj chlorine ces ua ke nrog ethylene uas tau los ntawm cov roj. Cov ntsiab lus tshwm sim yog ethylene dichloride, uas tau hloov pauv ntawm qhov kub siab heev rau vinyl chloride monomer. Cov monomer molecules no yog polymerized ua polyvinyl chloride resin.
YPuas yog polyvinyl chloride ua los ntawm roj av?
Zoo li txhua yam ntaub ntawv yas, PVC / yas tau los ntawm cov txheej txheem ua haujlwm uas hloov cov khoom siv hydrocarbon-raws li raw khoom (petroleum, natural gas lossis thee) rau hauv cov khoom siv hluavtaws hu ua polymers.
YPuas yog polyvinyl chloride ntuj?
Polyvinyl Chloride (PVC) yog ib qho ntawm cov khoom siv thermoplastic feem ntau siv thoob ntiaj teb (nrog rau ob peb yam khoom siv ntau dua li PET thiab PP). Nws yog naturally dawb thiab nkig heev (ua ntej ntxiv cov yas yas) yas.
