PVC payipi ntchito ndi makhalidwe

PVC hose ndi chida cha chitoliro chokhala ndi kulimba kolimba, kukana kutentha kwabwino, komanso ductility wabwino.Lili ndi magawo atatu: apamwamba, apakati, ndi apansi.Chipinda chapamwamba cha chubu cha PVC ndi filimu ya utoto, yomwe imagwira ntchito yoteteza madzi ndi kukalamba;Kupewa.Pali mitundu yambiri ya mafotokozedwe a chitoliro cha PVC, chifukwa ntchito yake ikhoza kugawidwa m'mitundu iwiri: chitoliro cha madzi ndi chitoliro cha mzere, kotero mankhwalawa ali ndi magulu ambiri.

PVC kumatheka payipi ndi mmodzi wa gulu la payipi pulasitiki, amene makamaka ntchito mafakitale, ulimi, nsomba ndi mipando.Ma hoses owonjezera a PVC amagawidwa m'magulu awiri.Imodzi ndi payipi ya PVC yowonjezera fiber.Chinthu chachikulu chomwe chimapangitsa kuti chiwongolero chake chikhudzidwe ndi fiber, chomwe chimatha kuwonjezeka pafupifupi 70%.Essence Ina ndi payipi ya waya ya PVC.Chofanana ndi payipi ya fiber ndi dongosolo lomwelo.Kukhudzidwa ndi kupsyinjika kwa mkati ndi kunja kwa nkhawa, kumatembenuka mosalekeza.Kupanikizika kwamtunduwu ndikwambiri kuposa kukakamiza kwa payipi ya PVC fiber.Chifukwa chake, mwachitsanzo, kugwiritsa ntchito mapampu amafuta, uinjiniya wa petroleum, ndi makina opanga fumbi amagwiritsidwa ntchito pamapampu amakanika, uinjiniya wamafuta, ndi makina opanga fumbi.

Mafotokozedwe a chitoliro cha PVC ndi gulu: Mapaipi a PVC amatha kugawidwa m'mitundu iwiri: mapaipi ofewa a PVC ndi mapaipi olimba a PVC molingana ndi katundu wosiyanasiyana.Kusiyanitsa kwakukulu ndikuti ili ndi mapulasitiki.Momwe makampani ali ndi chubu chofewa cha PVC, kotero kuti mawonekedwe ake ndi ofooka ndipo sangathe kupirira kuthamanga kwa madzi.Choncho, mapaipi ofewa a PVC amagwiritsidwa ntchito padenga, pansi, ndi pamwamba pa zikopa, ndipo nthawi zambiri amagwiritsidwa ntchito ngati machubu amawaya.Chubu cholimba cha PVC chilibe mapulasitiki.Ndizosavuta kuumba panthawi yopanga ndipo zimakhala ndi thupi labwino.Mapaipi olimba a PVC nthawi zambiri amagwiritsidwa ntchito ngati mapaipi a ngalande ndi mapaipi operekera madzi, ndipo amakhala ndi chitukuko chachikulu komanso kugwiritsidwa ntchito.Gawo la mipope yofewa ya PVC pamsika ndi gawo limodzi mwa magawo atatu, pomwe mapaipi olimba a PVC amawerengera magawo awiri pa atatu.Zopangira za chubu la PVC sizowonda kwathunthu, koma mutha kugwiritsa ntchito zothandizira zachilengedwe kuti zikhale zopanda poizoni zoteteza chilengedwe.
