Polyvinyl chloride resin S-700
I-Polyvinyl Chloride, ebizwa ngokuba yi-PVC, yenye yeentlobo zeplastiki eziphuculweyo, imveliso yangoku yesibini kuphela kwi-polyethylene.I-Polyvinyl chloride isetyenziswe ngokubanzi kwishishini, ezolimo kunye nobomi bemihla ngemihla.I-Polyvinyl chloride yikhompawundi yepolymer eyenziwe nge-vinyl chloride.Yinto thermoplastic.Umgubo omhlophe okanye okhanyayo ophuzi.Inyibilika kwiiketoni, ii-esters, i-tetrahydrofurans kunye ne-chlorinated hydrocarbons.Ukuchasana kweekhemikhali okugqwesileyo.Uzinzo olubi lwe-thermal kunye nokumelana nokukhanya, ngaphezu kwe-100 ℃ okanye ukukhanya kwelanga ixesha elide kwaqala ukubola i-hydrogen chloride, ukuveliswa kweplastiki kufuna ukongeza i-stabilizer.Ukufakelwa kombane kulungile, akusayi kutshisa.
IBanga le-S-700 lisetyenziswa ikakhulu ukuvelisa amaphepha acacileyo, kwaye anokuqengqeleka abe ngamashiti aqinileyo nangathi aqinile ukuze alungele ukupakishwa, imathiriyeli yomgangatho, ifilim eqinileyo yokugquma (yephepha lokusonga iilekese okanye ifilimu yokupakisha icuba), njl. njl. ikhutshelwe kwifilim eqinileyo okanye engaqinanga, ishiti, okanye ibha enemilo engaqhelekanga ukulungiselela ipakethe.Okanye inokutofwa ukwenza amajoyinti, iivalve, iinxalenye zombane, izixhobo zemoto kunye neenqanawa.
