He aha nā pohō e hana ʻia e ka chlorinated polyethylene CPE haʻahaʻa haʻahaʻa i ka hana ʻana o PVC?

ʻO ka polyethylene chlorinated (CPE) kahi huahana hoʻololi chlorinated o ka polyethylene kiʻekiʻe-density (HDPE), i hoʻohana ʻia ma ke ʻano he mea hoʻololi hana no PVC, Pono ka ʻike chlorine o CPE ma waena o 35-38%. Ma muli o kona kūpaʻa maikaʻi loa i ke aniau, ke kūpaʻa anu, ke kūpaʻa lapalapa, ke kūpaʻa aila, ke kūpaʻa hopena (he elastomer ka CPE), a me ke kūpaʻa kemika.
ʻO ka polyethylene chlorinated (CPE) kahi huahana hoʻololi chlorinated o ka polyethylene kiʻekiʻe-density (HDPE), i hoʻohana ʻia ma ke ʻano he mea hoʻololi hana no PVC, ʻO ka nui o ka chlorine o CPE ma waena o 35-38%. Ma muli o kona kūpaʻa maikaʻi loa i ke aniau, ke kūpaʻa anu, ke kūpaʻa lapalapa, ke kūpaʻa aila, ke kūpaʻa hopena (he elastomer ka CPE), a me ke kūpaʻa kemika, a me kona kūlike maikaʻi me PVC, ua lilo ʻo CPE i mea hoʻololi hoʻoikaika hopena i hoʻohana pinepine ʻia i ka hana ʻana o PVC.
1 Hoʻonohonoho Molekala o HDPE
Ma muli o nā kūlana hana like ʻole i ka wā o ka hopena polymerization o PE, aia kekahi mau ʻokoʻa i ka hoʻonohonoho molekala a me nā waiwai o kāna polymer HDPE. ʻOkoʻa pū nā waiwai o CPE ma hope o ka chlorination o HDPE me nā waiwai like ʻole. Pono nā mea hana CPE e koho i nā resins pauka kūikawā HDPE kūpono i mea e hana ai i nā resins CPE kūpono.
2. Nā kūlana chlorination, ʻo ia hoʻi ke kaʻina hana chlorination
ʻO CPE, ma ke ʻano he mea hoʻololi hana PVC, i hana pinepine ʻia e ka hopena chlorination me ka hoʻohana ʻana i ke ʻano chlorination hoʻokuʻu wai. ʻO nā kūlana koʻikoʻi o kēia kaʻina hana chlorination ka ikehu māmā, ka nui o ka mea hoʻomaka, ke kaomi hopena, ka mahana hopena, ka manawa hopena, a me nā kūlana hopena neutralization. He maʻalahi ke kumumanaʻo o ka chlorination PE, akā ʻoi aku ka paʻakikī o ke ʻano chlorination.
Ma muli o ka liʻiliʻi o ka hoʻopukapuka kālā ʻana i nā lako hana no ka hana ʻana i ka CPE, ua hoʻopuehu ʻia nā hale hana hana CPE liʻiliʻi he nui ma Kina. ʻAʻole wale kēia e hoʻohaumia i ke kaiapuni kaiaola, akā ʻo ia kekahi o nā kumu nui no ka paʻa ʻole o ka maikaʻi o ka CPE.
I kēia manawa, aia ka nui o nā CPE haʻahaʻa ma ka mākeke. Ma keʻano laulā, aia ʻelua ʻano o ka CPE haʻahaʻa. ʻO kekahi ma muli o kekahi mau hale hana hana ʻaʻole i loaʻa nā kūlana loea a me nā kaʻina hana chlorination kahiko. ʻO kekahi ʻano hana, ʻo ia ke kāwili ʻana i kahi nui o ka calcium carbonate a i ʻole ka pauka talc i loko o ka CPE e komo i ka hoʻokūkū kūpono ʻole.
