Kwa owonera wamba, pali kusiyana kochepa pakati pa chitoliro cha PVC ndi chitoliro cha UPVC.Onsewo ndi mapaipi apulasitiki omwe amagwiritsidwa ntchito kwambiri pomanga.Kupatula kufanana kwachiphamaso, mitundu iwiri ya mapaipi amapangidwa mosiyana ndipo motero amakhala ndi katundu wosiyana ndi ntchito zosiyana pang'ono pomanga ndi njira zina zamafakitale komanso kukonzanso-ntchito zambiri ku chitoliro cha pulasitiki ndi PVC osati uPVC.
Kupanga
PVC ndi UPVC amapangidwa makamaka ndi zinthu zomwezo.Polyvinylchloride ndi polima yomwe imatha kutenthedwa ndikuwumbidwa kuti ipange zinthu zolimba kwambiri, zolimba monga mapaipi.Chifukwa cha mawonekedwe ake olimba akapangidwa, opanga nthawi zambiri amaphatikiza ma polima owonjezera kukhala PVC.Ma polima awa amapangitsa chitoliro cha PVC kukhala chopindika kwambiri ndipo, nthawi zambiri, chimakhala chosavuta kugwiritsa ntchito kuposa ngati chikhala chosakhazikika.Zinthu zopangira pulasitiki zimasiyidwa pomwe uPVC imapangidwa - dzinalo ndi lalifupi la polyvinylchloride yopanda pulasitiki - yomwe imakhala yolimba ngati chitoliro chachitsulo choponyedwa.
Kugwira
Pazifukwa zoyika, chitoliro cha PVC ndi uPVC nthawi zambiri chimayendetsedwa mwanjira yomweyo.Onsewa amatha kudulidwa mosavuta ndi ma pulasitiki odula macheka kapena zida zamagetsi zomwe zimapangidwira kudula chitoliro cha PVC ndipo zonse zimalumikizidwa pogwiritsa ntchito gluing mankhwala m'malo mwa soldering.Chifukwa chitoliro cha UPVC chilibe ma polima opangira pulasitiki omwe amapangitsa kuti PVC ikhale yofewa pang'ono, iyenera kudulidwa bwino kukula kwake chifukwa sikuloleza kupereka.
Mapulogalamu
PVC chitoliro ntchito m'malo mkuwa ndi zitsulo zotayidwa mapaipi pa madzi sanali kumwa, m'malo zitsulo mapaipi mu mizere zinyalala, machitidwe ulimi wothirira ndi machitidwe dziwe kufalitsidwa.Chifukwa imalimbana ndi dzimbiri komanso kuwonongeka kuchokera kuzinthu zachilengedwe, ndi chinthu cholimba chomwe chimagwiritsidwa ntchito popanga mapaipi.Imadulidwa mosavuta ndipo zolumikizira zake sizifuna kutenthedwa, kumangiriza ndi guluu m'malo mwake, ndipo zimapereka zopatsa pang'ono pomwe mapaipi sali okulirapo bwino, kotero chitoliro cha PVC chimasankhidwa pafupipafupi ndi othandizira ngati njira yosavuta kugwiritsa ntchito chitsulo. kupopera.
Kugwiritsiridwa ntchito kwa uPVC sikunafalikire kwambiri pamipope ku America, ngakhale kukhazikika kwake kwathandizira kuti ikhale njira yopangira mizere ya zimbudzi, m'malo mwa chitoliro chachitsulo.Amagwiritsidwanso ntchito nthawi zambiri popanga ngalande zakunja monga mitsinje ya mvula.
Mtundu wokha wa chitoliro cha pulasitiki chomwe chiyenera kugwiritsidwa ntchito potumiza madzi akumwa ndi chitoliro cha cPVC.
