HDPE QHM32F HDPE-RF no ka paipu wela o ka papahele
ʻO QHM32F he resin polyethylene me ka hexene-1 ma ke ʻano he co-monomer i hana ʻia e ke kaʻina Unipol o UCC, USA.Loaʻa iā ia nā pōmaikaʻi o ka hiki ke hoʻololi maikaʻi, ka hana hoʻoponopono maikaʻi loa, ka paʻa wela a me ke kūpaʻa paʻa.Hoʻohana nui ʻia no ka hana ʻana i ka paipu hoʻomehana papahele, aluminika - paipu i hoʻohuihui ʻia, ka paipu lā.
ʻO ka paipu PE-RT he ʻano hou o nā mea polyethylene non-crosslinked i hiki ke hoʻohana ʻia i ka paipu wai wela.He copolymer ia o ka ethylene a me ka octene i hana ʻia e ka hoʻolālā molekala kūikawā a me ke kaʻina hana synthesis, me ka helu hoʻomalu o nā kaulahao lālā a me ka hoʻokaʻawale ʻana o nā ʻano polyethylene.ʻO ke ʻano molekole kūʻokoʻa e hana i ka mea i loaʻa i ke koʻikoʻi koʻikoʻi ke kūʻē ʻana a me ka ikaika hydrostatic lōʻihi.Hiki i ka paipu PE-RT ke ma'alahi, a he 550 MPa kona modulus kulou, a he ha'aha'a ke ko'iko'i o loko.Ma kēia ʻano, ʻaʻole hiki ke pohō ka paipu ma kahi e piʻo ai ma muli o ke koʻikoʻi koʻikoʻi.Ke kūkulu ʻia (ʻoi loa i ka hoʻoilo), ʻaʻole pono ia i nā mea hana kūikawā a i ʻole ka wela e kulou.ʻO ka wela wela o 0. 4 W/ (m·k), e like me ka paipu PE-X, ʻoi aku ka kiʻekiʻe ma mua o PP-R 0. 22 W/ (m·k) a me PB 0. 17 W/ (m·k), maikaʻi loa thermal conductivity, kūpono no ka papahele wela paipu
Palapala noi
ʻO QHM32F kahi resin kūikawā no ka paipu PE-RT i hana ʻia e Qilu Branch o Sinopec me ka hoʻohana ʻana i ka ʻenehana Unipol.Hiki i ka huahana ke hoʻololi maikaʻi, ka hana hoʻoponopono maikaʻi loa, ke kūpaʻa wela a me ke kū'ē i ke kaomi, hiki ke hoʻokō i nā koi o ka hana o ka paipu traction kiʻekiʻe o nā mea hana like ʻole a me ka caliber, a hiki ke hoʻohana ʻia no ka hana ʻana i ka paipu wela o ka papahele, alumini plastic composite. paipu, paipu aila, etc.
