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.

Lub ntsiab lus twg tsim cov tshuaj chloride nrog cov mis xcl?
Yog li ntawd, sodium thaum ua ke nrog cov tshuaj chlorine tuaj yeem tsim tau XCl . Lub ntsiab lus twg hauv daim ntawv ua cov tshuaj chloride ntawm hom XCl 2? Element X tsim cov tshuaj chloride nrog cov mis XCl 2, uas yog cov khoom uas muaj cov ntsiab lus melting siab.
Thaum twg siv polyvinyl cawv?
PVA yog siv hauv sizing tus neeg sawv cev uas muab lub zog ntau dua rau cov xov paj thiab ua rau daim ntawv tiv taus cov roj thiab roj ntau dua. Nws kuj yog siv los ua ib feem ntawm cov nplaum thiab cov emulsifiers, ua cov yeeb yaj kiab tiv thaiv dej, thiab ua cov khoom pib rau kev npaj ntawm lwm cov resins .
Qhov twg yog qhov mob thiab qhov twg yog qhov ceeb?
Panic (lub suab los ntawm Matt Frewer) yog lub ntsej muag ntsuab-xiav nrog lub cev ntev. Thaum nws yog me ntsis cunning dua Pain, nws paranoia txhais tau hais tias nws yog heev ceev faj thiab ntau cynical nyob rau hauv lub sij hawm, yog li nws tej zaum yuav ntse dua ib tug ntawm ob.
Qhov twg monomer siv los ua ke polyvinyl chloride?
PVC yog tsim los ntawm nws cov monomer, vinyl chloride. PVC yog cov yas tawv uas ua softer thiab hloov tau yooj yim los ntawm kev sib ntxiv ntawm cov yas yas, feem ntau siv yog phthalates . Qhov twg hauv qab no yog monomer ntawm polyvinyl chloride?
Thaum twg siv polyvinyl acetate?
Nyob hauv nws daim ntawv thov tseem ceeb tshaj plaws, polyvinyl acetate ua cov khoom siv ua yeeb yaj kiab hauv cov xim dej (latex) xim; nws kuj siv rau hauv cov nplaum . Vim li cas polyvinyl acetate siv los ua cov nplaum? PVA adhesives tsim cov yeeb yaj kiab zoo nkauj uas muaj huab cua zoo thiab tiv taus dej, roj, roj, thiab roj av.
