    Izici

    Ipulasitiki ye-PVC "ipulasitiki ye-polyvinyl chloride", iyimpushana emhlophe, umkhiqizo owenziwe ikakhulukazi nge-polymerization ye-vinyl chloride monomer, futhi wengeze ezinye izakhi zokuthuthukisa ukumelana nokushisa kwezimpahla, ukuqina kanye ne-ductility, ingenye yezinto ezivamile ze-thermoplastic.the umbala womkhiqizo ngokubi, I-Anti-corrosion, iqinile futhi ihlala isikhathi eside, Iphinde imelane nomlilo (inani lokubuyiswa komlilo ≥40), ukumelana namakhemikhali aphezulu (i-sulfuric acid ekugxilwe kuyo 90%, ukugxiliswa kwe-nitric acid 60% kanye nekhonsathi ye-Sodium hydroxide 20%), amandla emishini angcono kakhulu kanye Nokushisa okuhle. Kodwa ukumelana nokukhanya nokumelana nokushisa kubi kancane(iphuzu elithambisayo elingu-80℃,uma izinga lokushisa lingaphezu kuka-130℃,umbala uzoshintsha futhi uphume HCI), Ngakho-ke kumelwe sengeze isiqinisi ukuze sithuthukise ukumelana nokukhanya nokumelana nokushisa lapho sisetshenziswa.
