PVC resin SG5 K ixabiso 66-68 Polyvinyl chloride
Iimpawu
Iplastiki ye-PVC "iplastiki ye-polyvinyl chloride", ingumgubo omhlophe, imveliso eyenziwa ikakhulu yi-polymerization ye-vinyl chloride monomer, kwaye yongeze ezinye izinto zokuphucula ukuxhathisa ubushushu, ukuqina kunye ne-ductility, yenye yezinto eziqhelekileyo ze-thermoplastic.the umbala wemveliso ngokukrakra, I-Anti-corrosion, yomelele kwaye ihlala ixesha elide, Ikwanokumelana nomlilo (ixabiso lokubuyiswa komlilo ≥40), ukuxhathisa kwikhemikhali ephezulu (i-90% ye-sulfuric acid, i-acid ye-nitric i-60% kunye nekonsathi ye-Sodium hydroxide 20%), amandla agqwesileyo omatshini kunye nokugquma okulungileyo. Kodwa ukuxhathisa ukukhanya kunye nokumelana nobushushu kuncinci kubi (indawo yokuthambisa i-80 ℃, ukuba iqondo lobushushu lingaphezulu kwe-130 ℃, umbala uya kutshintsha kwaye uphume HCI), ke kufuneka songeze isizinzi sokuphucula ukumelana nokukhanya kunye nokumelana nobushushu xa sisetyenziswa.
