Waiwai PVC K 57
PVC K waiwai 57,
ʻO ka resin PVC i hoʻohana ʻia no ka hana ʻana i ka papa pahu,
Hiki ke hoʻohanaʻia ka PVC resin me kahi K waiwai o 55-68 no ka hanaʻana i ka paʻakikī paʻakikī,ʻo ia hoʻi, nā huahana PVC haʻahaʻa haʻahaʻa, heʻokoʻa ia mai ka waiwai K i hāʻawiʻia i nāʻike a me nā puke i hala.Ua hōʻike ʻia nā resins PVC me nā koina K o 69-77 i kūpono no ka hana ʻana i nā ʻūhā palupalu.Nui nā ala e hana ai i ka resin PVC, ke ʻano hoʻokuʻu, ke ʻano emulsion a me ka polymerization nui o ka resin PVC i loaʻa nā mea maka no nā huahana foamed, maʻamau ka hoʻokuʻu ʻana a me ka polymerization nui o ka resin PVC kūpono.ʻO nā copolymers PVC a me nā polymers i hoʻopili ʻia (granular polymers) maikaʻi nō hoʻi ke kaʻina hana a ʻaʻole hoʻohana ʻia ma muli o nā kumu kumu kūʻai.
ʻO ka Polyvinyl Chloride, i kapa ʻia ʻo PVC, ʻo ia kekahi o nā ʻano plastik i hana ʻia, ʻo ka lua o kēia manawa ka lua wale nō i ka polyethylene.Ua hoʻohana nui ʻia ka Polyvinyl chloride i ka ʻoihana, ka mahiʻai a me ke ola o kēlā me kēia lā.ʻO ka polyvinyl chloride kahi hui polymer polymerized e ka vinyl chloride.He thermoplastic.ʻO ka pauka melemele keʻokeʻo a i ʻole.Kūleʻa kemika maikaʻi loa.ʻO ke kūpaʻa wela maikaʻi ʻole a me ke kūpaʻa māmā, ʻoi aku ma mua o 100 ℃ a i ʻole ka lōʻihi o ka ʻike ʻana i ka lā i hoʻomaka e decompose hydrogen chloride, pono e hoʻohui i ka stabilizer.Maikaʻi ka insulation uila, ʻaʻole e wela.
Papa S-700Hoʻohana nui ʻia no ka hana ʻana i nā ʻāpana alohilohi, a hiki ke ʻōwili ʻia i loko o nā pepa ʻoʻoleʻa a semi-rigid no ka pūʻolo, nā mea papahele, nā kiʻi ʻoniʻoni paʻa no ka uhi ʻana (no ka pepa lole lole a i ʻole ke kiʻi ʻoniʻoni cigareti), a pēlā aku. kiʻiʻoniʻoni semi-paʻa, pepa, a i ʻole ʻano ʻano pā no ka pūʻolo.A i ʻole hiki ke hoʻopaʻa ʻia no ka hana ʻana i nā hui, nā ʻāpana, nā ʻāpana uila, nā lako kaʻa a me nā moku.
