Chitoliro cha polyvinyl chloride, chomwe chimanenanso kuti chitoliro cha pvc, ndi chubu chomwe pulasitiki yotentha kwambiri yopangidwa ndi polymerization ya vinyl choride monomer imapangidwa, kutenga polyvinyl chloride (PVC) RESINS ngati zopangira zazikulu, onjezerani woletsa kukalamba woyenera, wowongolera katundu. etc., zinthu kupanga kudzera njira monga kusakaniza, calendering, vacuum mapangidwe.

PVC chitoliro kukana dzimbiri ndi wamphamvu, ndi kugwirizana kukhala zosavuta, PVC ali kwambiri resistibility kwa oxygenant, reductive wothandizila ndi asidi amphamvu. mafuta, okhazikika nitric acid ndi wandiweyani oxidizing acid.

Koma, pvc chitoliro, makamaka UPVC chitoliro kukana toheat ndi osauka, ndi chilengedwe kumakoka mphamvu akutsika kuposa 60 ℃, ndipo pansi pa kutentha otsika chilengedwe, Vybak madzi mphukira kukana kuti zimakhudza mantha reduces. kuphulika;Kuphatikiza apo, magwiridwe antchito omwe chitoliro cha pvc chimalimbana ndi zododometsa ndizovuta.

Mtundu wa mipope yapamwamba ya polychlorethylene, yopangidwa ndi gawo la kulemera kwake:
