PVC mana paipu maka mea
PVC mana paipu maka mea,
PVC no ka paipu mana, pvc resin no ka paipu,
ʻO ka paipu mana PVC a me kāna ʻano hoʻomākaukau e komo i kēia mau mea maka:
100 polyvinyl chloride resin,
15-25 calcium carbonate,
5~10 titanium oxide,
4~8 mea hoʻololi i ka hopena,
2~5 mea hoʻopaʻa paʻa,
0.5~2 lubricant,
2~4 sepiolite
3~8 mea hoʻopaʻa ahi inorganic composite, composite inorganic flame retardant from rare earth hydroxide aluminum hydroxide Ke ʻano hoʻomākaukau o ka magnesium hydroxide a me ka zinc borate
Kaʻina hana:
1) E hoʻohui i ka calcium carbonate titanium oxide i loko o ka POLYvinyl chloride resin a hui pū me ka wikiwiki kiʻekiʻe no 3-6min;2) A laila hoʻohui i ka stabilizer modifier hopena, lubricant sepiolite a me ka composite inorganic flame retardant i loko o ka hui.
ʻO ka mahana hui ʻana he 100-110, a ʻo ka manawa hui ʻana he 10-15 mau minuke.Ma hope o ka hui ʻana o ka hui ʻana, ua hoʻoneʻe ʻia ka hui ʻana i ka hui hoʻoluʻu ma kahi haʻahaʻa haʻahaʻa o 40 ~ 50 no 3-5 mau minuke, a hope loa i loko o ka conical twin screw extruder ma 170 ~ 190 ʻO ka puʻupuʻu mana uila he ahi maikaʻi loa. ʻano mekini
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.
