Chikopa cha PVC ndi chinthu chopangidwa, chomwe chimadziwikanso kuti chikopa chopanga kapena chikopa choyerekeza. Amapangidwa ndi utomoni wa polyvinyl chloride (PVC) ndi zowonjezera zina kudzera munjira zingapo zopangira, ndipo amakhala ndi mawonekedwe ngati chikopa. Komabe, poyerekezera ndi chikopa chenicheni, PVC chikopa sichimakonda chilengedwe, chosavuta kuyeretsa, chosavala, komanso chosagwirizana ndi nyengo. Choncho, amagwiritsidwa ntchito kwambiri mu mipando, magalimoto, zovala, matumba ndi zina.
Choyamba, zopangira za PVC zikopa makamaka polyvinyl kolorayidi utomoni, amene ndi wamba pulasitiki zakuthupi ndi plasticity wabwino ndi kukana nyengo. Popanga zikopa za PVC, zida zina zothandizira monga plasticizers, stabilizers, fillers, komanso pigment ndi mankhwala othandizira pamwamba amawonjezeredwa kuti apange masitayelo ndi machitidwe osiyanasiyana a zida zachikopa za PVC kudzera kusanganikirana, kalendala, zokutira ndi njira zina.
Kachiwiri, chikopa cha PVC chili ndi zabwino zambiri. Choyamba, kupanga kwake kumakhala kosavuta komanso mtengo wake ndi wotsika, choncho mtengo wake ndi wochepa kwambiri, womwe ungathe kukwaniritsa zosowa za anthu ambiri. Kachiwiri, chikopa cha PVC chimakhala ndi kukana kwabwino kovala komanso kukana kwanyengo, sichovuta kukalamba kapena kupunduka, ndipo chimakhala ndi moyo wautali wautumiki. Chachitatu, chikopa cha PVC ndi chosavuta kuyeretsa, chosavuta kuchisamalira, chosavuta kuipitsidwa, komanso chosavuta kugwiritsa ntchito. Kuphatikiza apo, chikopa cha PVC chimakhalanso ndi zinthu zina zosagwirizana ndi madzi, zomwe zimatha kukana kukokoloka kwa madzi mpaka pamlingo wina, motero zagwiritsidwanso ntchito kwambiri nthawi zina zomwe zimafuna kuti madzi asagwe.
Komabe, chikopa cha PVC chilinso ndi zovuta zina. Choyamba, poyerekeza ndi chikopa chenicheni, chikopa cha PVC chimakhala ndi mpweya wochepa kwambiri ndipo chimakhala chovuta kuchigwiritsa ntchito kwa nthawi yaitali. Kachiwiri, chitetezo cha chilengedwe cha chikopa cha PVC chimakhalanso chotsutsana, chifukwa zinthu zovulaza zimatha kutulutsidwa panthawi yopanga ndikugwiritsa ntchito, zomwe zingakhudze chilengedwe ndi thanzi la anthu.
Chachitatu, chikopa cha PVC chimakhala ndi pulasitiki wosawoneka bwino ndipo sichosavuta kupanga kukhala zinthu zitatu-dimensional zovuta, chifukwa chake chimakhala chocheperako nthawi zina zapadera.
Nthawi zambiri, PVC chikopa, monga zakuthupi kupanga, wakhala ankagwiritsa ntchito mipando, magalimoto, zovala, matumba ndi minda ina. Ubwino wake monga kukana kuvala, kukana nyengo komanso kuyeretsa kosavuta kumapangitsa kukhala m'malo mwa zikopa zenizeni. Komabe, zofooka zake monga kuperewera kwa mpweya wabwino komanso chitetezo chokayikitsa cha chilengedwe chimafunanso kuti tizisamala tikamazigwiritsa ntchito, ndikusankha zinthu zoyenera kuti tikwaniritse zosowa zosiyanasiyana.
