ʻO nā mea maka no ka hoʻomākaukau ʻana i ka paipu PVC paʻa paʻa pālua ʻelua,
Mea maka no ka hana ʻana i nā paipu PVC lua-pā ʻāwili,
ʻO Polyvinyl Chloride (PVC) kahi resin thermoplastic linear i hana ʻia e ka polymerization o ka monomer vinyl chloride.Ma muli o ka ʻokoʻa o nā mea maka, ʻelua mau ala o ka synthesizing vinyl chloride monomer calcium carbide kaʻina a me ke kaʻina ʻaila.Hoʻohana ʻo Sinopec PVC i ʻelua kaʻina hana hoʻokuʻu, kēlā me kēia mai Japanese Shin-Etsu Chemical Company a me American Oxy Vinyls Company.Loaʻa i ka huahana ke kūpaʻa ʻino kemika maikaʻi, ka waiwai insulation uila maikaʻi a me ke kūpaʻa kemika maikaʻi.Me nā mea chlorine kiʻekiʻe, ʻoi aku ka maikaʻi o ke ahi a me nā mea hoʻopau ponoʻī.He mea maʻalahi ka PVC ma o ka extrusion, injection molding, calendering, blow molding, compressing, cast molding and thermal molding, etc.
Palapala noi
ʻO PVC kekahi o nā resins thermoplastic i hoʻohana nui ʻia.Hiki ke hoʻohana ʻia e hana i nā huahana me ka paʻakikī kiʻekiʻe a me ka ikaika, e like me nā paipu a me nā mea pono, nā puka profiled, nā puka makani a me nā pepa paʻi.
Hiki iā ia ke hana i nā huahana palupalu, e like me nā kiʻiʻoniʻoni, nā lau, nā uwea uila a me nā kaula, nā papa papahele a me nā ʻili synthetic, me ka hoʻohui ʻana i nā plasticizers.
