ʻO kekahi mau pilikia e pili ana i ka polyethylene chlorinated:

ʻO ka polyethylene chlorinated (CPE) kahi mea polymer saturated me ke ʻano pauka keʻokeʻo, ʻaʻohe ʻawaʻawa a ʻaʻohe ona ʻala. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka wā, ke kūpaʻa ozone, ke kūpaʻa kemika, a me ke kūpaʻa ʻana i ka ʻelemakule, a me ke kūpaʻa aila maikaʻi, ka pale ʻana i ka lapalapa, a me nā waiwai kala. ʻO ka paʻakikī maikaʻi (hiki ke loli ma -30 ℃), kūpono maikaʻi me nā mea polymer ʻē aʻe, ke kiʻekiʻe o ka mahana decomposition, hana ka decomposition i ka HCL, hiki ke hoʻoulu i ka hopena dechlorination o CPE.

ʻO ke ʻano hana wai o ka polyethylene chlorinated ka mea maʻamau e hoʻohana ʻia, nona nā kumukūʻai hana haʻahaʻa a me ka haumia haʻahaʻa. ʻO kekahi ʻano hana ʻo ia ke ʻano hoʻokuʻu, kahi i oʻo iki. Hiki i nā mea kūloko ke hana i ka hoʻomohala lua a me ka hoʻopili ʻana me ka hoʻomohala wikiwiki, a wikiwiki ka wikiwiki o ka maloʻo ʻana. Hoʻohana pinepine ʻia ia i loko o nā pahu mālama a me nā hale kila e hoʻomaikaʻi i ka palekana kūkulu.

ʻIke pinepine ʻia nā hiʻohiʻona polyethylene chlorinated home (CPE) e nā helu e like me 135A, 140B, a pēlā aku. Hōʻike nā helu mua 1 a me 2 i ke koena crystallinity (waiwai TAC), hōʻike ʻo 1 i ka waiwai TAC ma waena o 0 a me 10%, hōʻike ʻo 2 i ka waiwai TAC>10%, hōʻike nā helu ʻelua a me ke kolu i ka ʻike chlorine, no ka laʻana, hōʻike ʻo 35 i ka ʻike chlorine o 35%, a ʻo ka helu hope loa ka leka ABC, i hoʻohana ʻia e hōʻike i ke kaumaha molekala o ka mea maka PE. ʻO A ka mea nui loa a ʻo C ka mea liʻiliʻi loa.

Ka mana o ke kaumaha molekala: ʻO ka polyethylene chlorinated (CPE) ka mea i loaʻa ke kaumaha molekala kiʻekiʻe loa a me ka mānoanoa hoʻoheheʻe kiʻekiʻe i loko o kāna mea ʻano-A. ʻO kona mānoanoa e kūlike loa me PVC a loaʻa iā ia ka hopena hoʻopuehu maikaʻi loa ma PVC, e hana ana i kahi ʻano hoʻopuehu e like me ka pūnaewele kūpono. No laila, koho pinepine ʻia ka mea ʻano-A o CPE ma ke ʻano he mea hoʻololi no PVC.

Hoʻohana nui ʻia no: uea a me ke kaula (nā kaula lanahu, nā kaula i kuhikuhi ʻia ma nā kūlana UL a me VDE), hose hydraulic, hose kaʻa, lipine, pā laholio, hoʻololi ʻana i ka paipu PVC profile, nā mea magnetic, hoʻololi ABS, a pēlā aku. ʻO ka hoʻomohala ʻana o ka ʻoihana uea a me ke kaula a me ka ʻoihana hana ʻāpana kaʻa ua hoʻoulu i ke koi no ka hoʻohana ʻana i ka CPE ma muli o ka laholio. ʻO ka CPE ma muli o ka laholio he laholio synthetic kūikawā me ka hana piha maikaʻi loa, ke kūpaʻa wela i ka oxygen a me ka ʻelemakule ozone, a me ka pale ahi maikaʻi loa.

Nā mea e pili ana i ka mahana o ka decomposition thermal o CPE

Pili nā waiwai o CPE i kona nui chlorine. Inā kiʻekiʻe ka nui o ka chlorine, ʻoi aku ka maʻalahi o ka palaho ʻana;

Pili ia i ka maʻemaʻe. ʻO ka wehe ʻole ʻana o nā mea hoʻomaka, nā mea hoʻouluulu, nā waikawa, nā kumu, a me nā mea ʻē aʻe i hoʻohui ʻia i ka wā o ke kaʻina hana polymerization, a i ʻole ka omo ʻana o ka wai i ka wā o ka mālama ʻana a me ka lawe ʻana, hiki ke hōʻemi i ke kūpaʻa o ka polymer. Hiki i kēia mau mea ke hana i nā hopena hōʻino ion molekala, a loaʻa i ka CPE nā mea kaumaha molekala haʻahaʻa e like me Cl2 a me HCl, hiki ke hoʻolalelale i ka decomposition thermal o ka resin;
