Raw zvinhu zvekugadzirira marata maviri-madziro akaoma PVC pombi,
Raw zvinhu zvekugadzira marata maviri-madziro PVC pombi,
Polyvinyl Chloride (PVC) iine mutsara thermoplastic resin inogadzirwa ne polymerization yevinyl chloride monomer.Nekuda kwekusiyana kwezvinhu zvakabikwa, kune nzira mbiri dzekugadzira vinyl chloride monomer calcium carbide process uye petroleum process.Sinopec PVC inotora maitiro maviri ekumisa, zvichiteerana kubva kuJapan Shin-Etsu Chemical Company neAmerican Oxy Vinyls Company.Chigadzirwa chine yakanaka makemikari corrosion kuramba, yakanakisa magetsi ekudzivirira zvivakwa uye yakanaka kugadzikana kwemakemikari.Iine yakakwira chlorine yemukati, iyo nyaya ine yakanaka retardance yemoto uye yekudzima-inodzima zvinhu.PVC iri nyore kugadzirisa ne extrusion, jekiseni kuumba, calendering, kuvhuvhuta kuumbwa, compressing, kuumbwa kuumbwa uye kuumbwa kwekupisa, nezvimwe.
Application
PVC ndeimwe yeanonyanya kushandiswa thermoplastic resins.Inogona kushandiswa kugadzira zvigadzirwa zvine kuomarara kwepamusoro uye kusimba, senge pombi uye zvishongedzo, magonhi ane profiled, mahwindo uye mapepa ekurongedza.
Inogonawo kugadzira zvigadzirwa zvakapfava, senge mafirimu, mashizha, waya dzemagetsi netambo, floorboards uye synthetic dehwe, nekuwedzera kweplasticizers.
