PVC K boleng 57,
Resin ea PVC e sebelisetsoang ho etsa foam board,
Resin ea PVC e nang le boleng ba K ea 55-68 e ka sebelisoa ho etsa foam e thata, ke hore, lihlahisoa tse thata tsa PVC tse nang le foam, tse fapaneng le boleng ba K bo fanoeng nakong e fetileng boitsebiso le libuka.Li-resin tsa PVC tse nang le litekanyetso tsa K tsa 69-77 li bontšitsoe hore li loketse ho etsa liforomo tse bonolo.Ho na le mekhoa e mengata ea ho hlahisa resin ea PVC, mokhoa oa ho fanyeha, mokhoa oa emulsion le polymerization e ngata ea resin ea PVC e fumaneha lisebelisoa tse tala bakeng sa lihlahisoa tse foamed, hangata ho fanyeha le polymerization e ngata ea PVC resin e loketse.Li-copolymers tsa PVC le li-polymer tse hlomathisitsoeng (li-polymers tse granular) le tsona li na le ts'ebetso e ntle 'me ha li sebelisoe ka seoelo ka lebaka la lintlha tsa theko.
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.
