PVC S-700
PVC S-700,
lishiti tse bonaletsang PVC resin,
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.
Grade S-700 e sebelisoa haholo-holo ho hlahisa li-flakes tse bonaletsang, 'me e ka hatelloa ho selae se thata kapa se thata-thata kapa lakane bakeng sa sephutheloana, thepa ea fatše, filimi e thata bakeng sa lesela (bakeng sa pampiri ea lipompong kapa filimi ea ho paka sakerete), joalo-joalo. hape e fetisetsoe selae se thata kapa se thata, lakane, kapa bareng e sa bōpehileng hantle bakeng sa sephutheloana.Kapa e ka enteloa ho etsa manonyeletso, li-valve, likarolo tsa motlakase, lisebelisoa tsa likoloi le likepe.
