Pamene maonekedwe a thovu a PVC adayambitsidwa m'ma 1970, adatchedwa "matabwa amtsogolo," ndipo mankhwala awo ndi polyvinyl chloride.Chifukwa cha kufalikira kwa zinthu zolimba za PVC zotsika thovu, zimatha kulowa m'malo mwazinthu zonse zamatabwa.
M'zaka zaposachedwa, ukadaulo wa opanga chithovu a PVC wapitanso patsogolo mwachangu, kulola kuti zinthu zolimba za thovu za PVC zikhale zopanga mafakitale m'magawo azinthu zamamangidwe ndi zokongoletsera, komanso kapangidwe kazinthu zapanyumba.
Powonjezera chodzaza chosiyana pazinthu za thovu la PVC, mawonekedwe osiyanasiyana amaperekedwa kuzinthu zolimba za thovu la PVC.Imawonjezera kuchuluka kwa kugwiritsidwa ntchito kwa mankhwalawa m'malo ena ogwiritsira ntchito zida zosiyanasiyana zomangira ndi zokongoletsera zokongoletsera.Nthawi yomweyo zinthu zolimba za thovu za PVC zimakhala ndi zinthu zokongoletsa pamwamba.
Umboni wa chinyezi, anti-corrosion, retardant flame, non-poizoni, komanso fungo la PVC foam profile materials Mtundu wamtunduwu ukhoza kusintha bwino malo okhala, ndipo ndondomeko ya thovu ya PVC tsopano ndiyo kugwiritsa ntchito chithovu cholimba cha PVC ndi thovu lotumphuka. bolodi, komanso zina PVC thovu zakuthupi kukongoletsa mbiri, kupanga sikelo ya mankhwala luso.Kugwiritsiridwa ntchito kwa kafukufuku kukuchulukirachulukira pankhani yomanga, kulongedza katundu, mipando, ndi madera ena.
Pamwamba pa bolodi la thovu la PVC limatha kupopera mbewu mankhwalawa, zomwe zingapewe kusintha kwamtundu wamtundu ndipo zimakhala ndi mwayi wotsutsana ndi kuuma kwapamwamba.Ndiye pali njira yathu wamba processing kupanga, mu phala pamwamba pa kristalo mbale, processing ambiri adzakhala makamaka basi m'mphepete kusindikiza makina, ndi basi m'mphepete kusindikiza makina zingakhudzire ogaŵikana dongosolo wodzigudubuza mtundu komanso crawler mtundu awiri, koma ngati ayi. gwiritsani ntchito thovu lopanda kanthu pamene tikulimbikitsidwa kugwiritsa ntchito ndipo phala la pamwamba lili ndi mtundu wofanana, pewani phala la pepala pakukula kwa shrinkage powonetsa kuti mapangidwewo ali ndi kusiyana koonekeratu kwamitundu.
