Kusiyana pakati pa PVC chingwe ndi mphira chingwe

1.zinthu ndizosiyana, chingwe cha PVC chimapangidwa ndi chingwe chimodzi kapena zingapo zamkuwa zamkuwa, pamwamba pake zimakutidwa ndi wosanjikiza wa insulator, kuteteza kukhudzana ndi woyendetsa. Kondakitala wamkati amagawidwa m'mitundu iwiri ya mkuwa wopanda kanthu ndi mkuwa wopangidwa ndi malata molingana ndi miyezo yoyenera. Waya wa mphira, womwe umadziwikanso kuti waya wopaka mphira, ndi mtundu wa waya wotsekeredwa pawiri; Khungu lakunja ndi kusungunula kumapangidwa ndi mphira, kondakitala ndi mkuwa weniweni, ndipo wosanjikizawo amakhala ndi chlorinated polyethylene (CPE).
2. Kugwiritsa ntchito zosiyanasiyana,mphira chingwendi oyenera AC oveteredwa voteji 300V/500V ndi 450/750V ndi pansi zipangizo mphamvu, zipangizo zapakhomo, zida magetsi, kuunikira zomangamanga ndi makina zofunika mkati mwa malo ofewa kapena mafoni, monga mizere kugwirizana magetsi kapena mawaya. Waya wa PVC umagwiritsidwa ntchito makamaka polumikizira mkati mwa zida zamagetsi ndi zamagetsi.
3. makhalidwe ndi osiyana, PVC mzere chitoliro pamwamba ndi yosalala, kukana madzimadzi ndi yaing'ono, si makulitsidwe, ndipo si oyenera kuswana tizilombo. Coefficient ya kukula kwa matenthedwe ndi yaying'ono, ndipo sichimachepa ndi kupunduka. Waya wamphira uli ndi kukana kwanyengo komanso kukana kwina kwamafuta, kumatha kupirira mphamvu zazikulu zamakina zakunja, zofewa, zosalala bwino, kukana kuzizira, kukana kwa ultraviolet, kusinthasintha kwabwino, mphamvu yayikulu.
