Daim ntawv thov
PVC yog ib tug polymer ntawm vinyl chloride monomer nyob rau hauv ib tug pib xws li peroxide los yog ib tug azo compound;los yog ib tug polymer tau los ntawm ib tug dawb radical polymerization mechanism nyob rau hauv qhov kev txiav txim ntawm lub teeb los yog kub.Nws yog cov khoom siv thermoplastic uas pheej yaj ntawm qee qhov kub thiab ua kom txias rau qhov txias.Nws lub ntsiab tivthaiv yog polyvinyl chloride, ib yam khoom uas ntxiv lwm cov khoom xyaw los txhim kho nws cov cua sov, toughness thiab ductility.PVC muab faib ua nruj thiab yoog raws thiab tuaj yeem ua ke nrog ntau yam khoom siv los ua cov kav dej mos thiab tawv PVC.PVC-U yeeb nkab muaj zog corrosion kuj, kev sib txuas yooj yim, tus nqi qis thiab kev ntxhib los mos.Nws yog siv rau hauv cov kav dej, dej khib nyiab, tshuaj, cov khoom siv cua sov thiab cov dej txias, cov khoom noj, cov kua ntshiab ntshiab, av nkos, roj, compressed cua thiab lub tshuab nqus tsev.
