calcium carbide njira PVC mtengo
njira ya calcium carbideMtengo wa PVC,
PVC ndi njira ya calcium carbide, Mtengo wapatali wa magawo PVC,
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
Posachedwapa, ngakhale mtengo waPVC ndi njira ya calcium carbidewatsika pang'ono, si waukulu ngati kutsika kwa mtengo wa PVC.Phindu lalikulu la mabizinesi a PVC pogwiritsa ntchito njira ya calcium carbide likupitilirabe kuchepa, ndipo mabizinesi a PVC opanga ma TV akunja ku East China adasanduka mtengo woyipa kumapeto kwa Juni.Pofika kumapeto kwa June 23, phindu lalikulu la njira ya East China carbide inali -133 yuan/ton, yomwe idatsika ndi 622 yuan/ton.Pakadali pano, mtengo wokwezedwa ndi mabizinesi a calcium carbide PVC ku East China ukadali wokwera kwambiri, ndipo kutsika kwamitengo kumachedwa komanso mochedwa.Mabizinesi akukumana ndi magawo osiyanasiyana azovuta zoperekera, kotero pakanthawi kochepa, mtengowo umakhalabe makamaka kugwa ndi kugwa, palibe chiyembekezo chosintha zomwe zidatayika.Munkhaniyi, msika udayamba kutchula kuchuluka kwa chlor-alkali ndi alkali kuti akweze chlorine, makamaka caustic soda yamadzimadzi ya chlorine imayenera kugayidwa.
