Monga chinthu chodziwika bwino komanso chotsika mtengo chotseka zinthu m'banja la rabara lotseka zinthu, zingwe zotsekera zinthu za rabara za PVC zimagwiritsidwa ntchito kwambiri pokongoletsa zinthu zapakhomo, zitseko ndi mawindo wamba, mipando, zida zamagetsi ndi zinthu zina zotsekera zinthu za tsiku ndi tsiku, zomwe zimagwira ntchito yayikulu pamsika wotseka zinthu wapakati komanso wotsika. Ndi ukadaulo wopanga zinthu wokhwima komanso khalidwe lokhazikika la zinthu, zingwe zotsekera zinthu za PVC zakhala chisankho chabwino kwambiri pamapulojekiti ambiri okongoletsa zinthu wamba komanso mafakitale ang'onoang'ono komanso apakatikati opanga zida chifukwa cha mtengo wake wokwera, kukonza kosavuta komanso kalembedwe kake kolemera.
Chingwe chotsekera rabara cha PVC chimapangidwa ndi zinthu zosinthidwa za polyvinyl chloride, zosakanikirana ndi zofewetsa, choletsa kukalamba ndi zinthu zina zothandizira, zokhala ndi kusinthasintha kwabwino, kukana kuwonongeka komanso kukana kupindika. Chogulitsachi ndi chopepuka, chosavuta kudula ndikuyika, ndipo chitha kusinthidwa kuti chigwirizane ndi mipata yosiyanasiyana yosasinthasintha. Mosiyana ndi zipangizo za rabara zogwira ntchito kwambiri monga EPDM ndi rabara ya silicone, mipiringidzo yotsekera ya PVC ili ndi magwiridwe antchito apakati komanso mitengo yotsika mtengo, yomwe ingakwaniritse zosowa za tsiku ndi tsiku zotsekera zamkati popanda zofunikira zolimbana ndi nyengo. Ndi yoyenera makamaka zitseko zamatabwa zamkati, zitseko za makabati, mipata ya zovala, zitseko ndi mawindo a aluminiyamu amkati, komanso kutsekera zida zamagetsi zapakhomo.
Ponena za magulu a zinthu, mipiringidzo yotsekera ya PVC imagawidwa m'magulu awiri: PVC yowonekera bwino, PVC yosalala, PVC yopangidwa ndi thovu ndi PVC yolimba komanso yofewa. Mipiringidzo yotsekera ya PVC yopangidwa ndi thovu imakhala ndi mphamvu zabwino kwambiri zotetezera mawu komanso zotetezera, zomwe zimachepetsa phokoso la kugundana pamene zitseko ndi mawindo atsekedwa ndipo zimathandiza kuteteza kugundana. Zinthu za PVC zowonekera bwino komanso zosalala zimakhala zokongola, zogwirizana ndi mitundu yosiyanasiyana yokongoletsera, ndipo sizikhudza kukongoletsa konse kwa nyumba ndi mipando. Chogulitsachi chili ndi mphamvu yabwino yosalowa madzi komanso yosalowa fumbi, zomwe zingalepheretse fumbi laling'ono, udzudzu ndi mpweya wonyowa kulowa mchipindamo, ndikuwonjezera ukhondo wamkati ndi chitonthozo.
M'zaka zaposachedwapa, miyezo yowonjezereka yoteteza chilengedwe m'makampani yachepetsa zinthu zachikhalidwe za PVC zosalimba, ndipo zingwe zatsopano zotsekera za PVC zosinthidwa zachilengedwe zikutchuka kwambiri pamsika. Mafomula osinthidwa amachotsa mapulasitiki owopsa, omwe alibe fungo, osakhala ndi poizoni komanso otsatira kwathunthu malangizo achitetezo am'nyumba ndi apadziko lonse lapansi. Ngakhale kuti zingwe za PVC sizili kumbuyo kwa zinthu za EPDM ndi silicone zomwe sizimatentha kwambiri komanso sizimalekerera kukalamba panja, zimakwaniritsa bwino zofunikira zautumiki wanthawi yayitali m'malo otsekedwa mkati. Chifukwa cha ntchito yokwera mtengo kwambiri komanso kusinthasintha kosiyanasiyana, zingwe zotsekera za mphira za PVC zimasunga magawo okhazikika pamsika ndipo zimakhalabe zowonjezera zotsekera zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi m'mapulojekiti okongoletsera nyumba padziko lonse lapansi.
