Kodi mapaipi a PVC Amapangidwa bwanji?,
Mtengo wa PVC, PVC Pipe Raw Material,
PVC ndi chidule cha polyvinyl chloride.Utomoni ndi zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri popanga mapulasitiki ndi mphira.PVC resin ndi ufa woyera womwe umagwiritsidwa ntchito popanga thermoplastics.Ndi zinthu zopangidwa zomwe zimagwiritsidwa ntchito kwambiri padziko lapansi masiku ano.Utoto wa polyvinyl chloride uli ndi mawonekedwe abwino kwambiri monga zopangira zambiri, ukadaulo wopanga okhwima, mtengo wotsika, komanso ntchito zosiyanasiyana.Ndiosavuta pokonza ndipo akhoza kukonzedwa ndi akamaumba, laminating, jekeseni akamaumba, extrusion, calendering, kuwomba akamaumba ndi njira zina.Ndi katundu wabwino wakuthupi ndi mankhwala, amagwiritsidwa ntchito kwambiri m'makampani, zomangamanga, ulimi, moyo watsiku ndi tsiku, kulongedza katundu, magetsi, zofunikira za boma, ndi zina.Ma resin a PVC nthawi zambiri amakhala ndi kukana kwambiri kwamankhwala.Ndi yamphamvu kwambiri ndipo imagonjetsedwa ndi madzi ndi abrasion.Polyvinyl chloride resin (PVC) imatha kusinthidwa kukhala zinthu zapulasitiki zosiyanasiyana.PVC ndi mapulasitiki opepuka, otsika mtengo, komanso osamalira chilengedwe.Pvc Resin angagwiritsidwe ntchito mapaipi, mafelemu zenera, hoses, zikopa, zingwe waya, nsapato ndi zina zonse zolinga zofewa, mbiri, zovekera, mapanelo, jekeseni, akamaumba, nsapato, chubu cholimba ndi zipangizo zokongoletsera, mabotolo, mapepala, kalendala, jekeseni okhwima ndi akamaumba, etc. ndi zigawo zina.
Mawonekedwe
PVC ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi thermoplastic resins.Itha kugwiritsidwa ntchito kupanga zinthu zolimba kwambiri komanso zolimba, monga mapaipi ndi zokokera, zitseko zojambulidwa, mazenera ndi mapepala onyamula.Itha kupanganso zinthu zofewa, monga mafilimu, mapepala, mawaya amagetsi ndi zingwe, matabwa apansi ndi zikopa zopangira, powonjezera mapulasitiki.

Kugwiritsa ntchito
Mapaipi a PVC amapangidwa ndi extrusion ya PVC yopangira, ndipo nthawi zambiri amatsata njira zomwezo zomwe zimagwira chitoliro cha extrusion:
Kudyetsa zopangira ma pellets / ufa mu PVC twin screw extruder
Kusungunuka ndi kutentha m'magawo angapo a extruder
Kutuluka kudzera mu ufa kuti apange chitoliro
Kuzizira kwa chitoliro chopangidwa
Kudula mapaipi a PVC mpaka kutalika komwe mukufuna
Komabe, ngakhale ali ndi njira yofananira yopangira mapaipi ambiri apulasitiki, mapaipi a PVC ali ndi mawonekedwe omwe amabweretsa zovuta zina kwa opanga mapaipi potengera kupanga, komanso kuyika malonda awo pamsika.
