Polyvinyl chloride resin S-700
Polyvinyl Chloride, e bitsoang PVC, ke e 'ngoe ea mefuta ea polasetiki e tsoetseng pele ea indasteri, tlhahiso ea hona joale ke ea bobeli feela ho polyethylene.Polyvinyl chloride e sebelisitsoe haholo indastering, temong le bophelong ba letsatsi le letsatsi.Polyvinyl chloride ke motsoako oa polymer o entsoeng ka vinyl chloride.Ke thermoplastic.Phofo e tšoeu kapa e bobebe e mosehla. E qhibiliha ka har'a li-ketone, esters, tetrahydrofuran le li-hydrocarbon tse chlorine.E babatsehang khanyetso ea lik'hemik'hale.Botsitso bo fokolang ba mocheso le ho hanyetsa khanya, ho feta 100 ℃ kapa ho pepeseha ha nako e telele ho letsatsi ho ile ha qala ho bola hydrogen chloride, tlhahiso ea polasetiki e hloka ho eketsa stabilizer.Insulation ea motlakase e ntle, e ke ke ea chesa.
Sehlopha sa S-700e sebelisoa haholo ho hlahisa lipampiri tse bonaletsang, 'me e ka phuthoa ka har'a maqephe a thata-thata bakeng sa sephutheloana, thepa ea fatše, filimi e thata bakeng sa lesela (bakeng sa pampiri e phuthelang lipompong kapa filimi ea ho paka sakerete), joalo-joalo E ka boela ea fetisetsoa ho thata kapa filimi, lakane, kapa sebōpeho se sa tsitsang bakeng sa sephutheloana.Kapa e ka enteloa ho etsa manonyeletso, li-valve, likarolo tsa motlakase, lisebelisoa tsa likoloi le likepe.
