PVC S-700
PVC S-700,
nā lau ʻaʻahu PVC resin,
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.
Hoʻohana nui ʻia ka papa S-700 no ka hana ʻana i nā flakes alohilohi, a hiki ke kaomi ʻia i kahi ʻāpana paʻakikī a i ʻole semi-paʻakikī a i ʻole pepa no ka pūʻolo, mea papahele, kiʻi ʻoniʻoni paʻa no ka uhi ʻana (no ka pepa lole lole a i ʻole kiʻi ʻoniʻoni paka), a pēlā aku. e hoʻokuʻu ʻia i kahi ʻāpana paʻakikī a i ʻole semi-paʻakikī, pepa, a i ʻole ke ʻano ʻano ʻano ʻole 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.
