PVC resin yog ib qho polymer compound tsim los ntawm polymerization ntawm vinyl chloride monomer (VCM), thiab nws cov qauv unit yog [CH2-CHCL]n. polymerization degree feem ntau yog 590-1500. Raws li cov ntsiab lus ntawm cov polyethylene monomer seem hauv PVC residues tuaj yeem faib ua: qib kev lag luam, qib kev huv zaub mov, qib kev kho mob peb. Cov tsos ntawm PVC resin yog hmoov dawb.
Khoom
Polyvinyl chloride resin yog ib qho polymer compound polymerized los ntawm vinyl chloride monomer (VCM), thiab nws cov qauv unit yog [CH2-CHCL] n. Qib ntawm polymerization feem ntau yog nyob rau hauv qhov ntau ntawm 590-1500. Raws li cov ntsiab lus ntawm cov polyethylene monomer seem hauv PVC residue, nws tuaj yeem faib ua qib kev lag luam, qib zaub mov huv thiab qib kev kho mob. Cov tsos ntawm PVC resin yog hmoov dawb.
siv
PVC resin muaj ntau yam kev siv. Raws li kev siv sib txawv, cov khoom siv ua tiav tsim nyog tuaj yeem ntxiv. Cov khoom yas PVC tuaj yeem qhia txog cov khoom siv lub cev thiab cov khoom siv sib txawv. Nws tuaj yeem tsim cov khoom tawv, cov khoom mos, tawv cuav, txheej thiab cov nplaum. Qhov muaj txiaj ntsig zoo tshaj plaws hauv kev lag luam yog nws tus nqi lag luam, kev sib xyaw zoo heev nrog cov khoom sau, kev ua tiav yooj yim, kev ntxhib los mos, kev rwb thaiv tshav kub, kev tshem tawm suab nrov, kev tiv thaiv hluav taws thiab lwm yam. Nws yog ib qho ntawm cov yas loj tshaj plaws hauv ntiaj teb.
