SINOPEC Ethylene Raws li PVC Resin S700 K57
SINOPEC Ethylene Raws li PVC Resin S700 K57,
PVC cob rau WPC board,
Polyvinyl Chloride, hu ua PVC, yog ib qho ntawm cov khoom siv yas yas, cov zis tam sim no tsuas yog thib ob rau polyethylene.Polyvinyl chloride tau siv dav hauv kev lag luam, kev ua liaj ua teb thiab lub neej txhua hnub.Polyvinyl chloride yog ib qho polymer compound polymerized los ntawm vinyl chloride.Nws yog thermoplastic.Dawb los yog lub teeb daj hmoov.Nws yog soluble hauv ketones, esters, tetrahydrofurans thiab chlorinated hydrocarbons.Cov tshuaj tiv thaiv zoo heev.Tsis zoo thermal stability thiab lub teeb tsis kam, ntau tshaj 100 ℃ los yog lub sij hawm ntev raug tshav ntuj pib decompose hydrogen chloride, yas manufacturing yuav tsum tau ntxiv stabilizer.Hluav taws xob rwb thaiv tsev zoo, yuav tsis hlawv.
Qib S-700Feem ntau yog siv los tsim cov ntawv pob tshab, thiab tuaj yeem muab dov rau hauv cov ntawv tsis sib xws thiab ib nrab nruj rau pob, cov khoom siv hauv pem teb, cov zaj duab xis tawv rau hauv ob sab phlu (rau cov khoom qab zib wrapping ntawv lossis luam yeeb ntim zaj duab xis), thiab lwm yam. Nws kuj tuaj yeem raug extruded nyuaj los yog semi-hard zaj duab xis, daim ntawv, los yog irregularly zoo li tus bar rau pob.Los yog nws tuaj yeem raug txhaj tshuaj los ua cov pob qij txha, li qub, cov khoom siv hluav taws xob, cov khoom siv pib thiab cov hlab ntsha.
