ʻO nā ʻano like ʻole a me nā noi o ka CPE chlorinated polyethylene

CPE, ʻO ka polyethylene chlorinated, i ʻike ʻia hoʻi he chlorinated polyethylene, ua hana ʻia mai ka polyethylene kiʻekiʻe-density kūikawā (HDPE) ma o ke kaʻina hana chlorination. ʻO ke ʻano o kēia mea, ʻo ia ka hoʻololi hapa ʻia ʻana o nā ʻātoma hydrogen i loko o kona kaulahao molekala e nā ʻātoma chlorine, e hōʻike ana i kahi ʻano kemika kū hoʻokahi. ʻIke ʻia ka CPE maloʻo ma ke ʻano he pauka keʻokeʻo a ʻaʻohe mea ʻawaʻawa a palekana. ʻO kona ʻano molekala ʻo CH2-CHCl-CH2-CH2] n, i hoʻopōkole ʻia e like me CPE a i ʻole CM ma ka ʻōlelo Pelekania. Ma ke ʻano he mea polymer saturated, ʻaʻole wale ka CPE i ke kūpaʻa maikaʻi o ka wā a me ke kūpaʻa lapalapa, akā hōʻike pū kekahi i ke kūpaʻa wela maikaʻi loa, ʻoi aku ka maikaʻi ma mua o PVC. Eia kekahi, loaʻa iā ia nā pono o ke kumukūʻai haʻahaʻa a me ka hana maikaʻi loa. Ma ke ʻano o ka solubility, hiki ke hoʻoheheʻe ʻia ka CPE i loko o nā hydrocarbons ʻala a me nā hydrocarbons halogenated, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o nā hydrocarbons aliphatic. Ke ʻoi aku ka mahana ma mua o 170 ℃, hoʻomaka ia e decompose a hoʻokuʻu i ke kinoea hydrogen chloride. Ma muli o kona ʻano kemika paʻa, hōʻike pū ka CPE i ke kūpaʻa ʻelemakule maikaʻi loa, ke kūpaʻa anu, ke kūpaʻa kemika, ke kūpaʻa ozone, a me ka insulation uila. I ka manawa like, loaʻa iā ia ka hoʻohālikelike maikaʻi a me ka hiki ke hana ʻia, a hiki ke hui pū ʻia me nā mea e like me PVC, PE, PS, a me ka laholio, e hoʻomaikaʻi pono ana i nā waiwai kino o kēia mau mea.
He nui nā noi o CPE ma nā ʻano like ʻole
1. Hoʻohana ʻia i loko o ka membrane pale wai
ʻO ka membrane pale wai PVC i hoʻonui ʻia e CPE, me nā ʻano maikaʻi loa o CPE, ua hoʻonui nui i kona ikaika tensile ma 80% a me ka ikaika haehae ma 50%. I ka manawa like, ua hoʻonui piha ʻia kona kūpaʻa ʻana i ka wā mechanical, ke kūpaʻa haʻahaʻa haʻahaʻa, a me ke kūpaʻa ʻelemakule, a makemake nui ʻia e nā keʻena kūkulu (me ka hoʻohui CPE i kāohi ʻia ma 10% -15%). Eia kekahi, ua lilo ka membrane pale wai chloroprene rubber CPE a me ka membrane pale wai chloroprene rubber CPE styrene butadiene rubber i hanauna hou o nā mea pale wai kūpono me ko lākou ikaika kiʻekiʻe, elasticity kiʻekiʻe, hiki ke hoʻonui ʻia, a me nā pono he nui e like me ke kūpaʻa ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa anu, ke kūpaʻa ʻelemakule, a me ka pale ahi, a he mau manaʻolana ākea ko lākou.
2. Hana ʻana i nā puka a me nā puka makani plastik
Ma ka hoʻohui ʻana iā CPE me PVC, ua hoʻomaikaʻi nui ʻia ka elasticity, ka paʻakikī, a me ka hana haʻahaʻa o nā puka plastik a me nā puka makani, me ka loaʻa ʻana o ke kūpaʻa maikaʻi i ka wā, ke kūpaʻa wela, a me ke kūpaʻa kemika. He kūpono ke kumukūʻai o kēia ʻano puka plastik a me nā puka makani, kūpaʻa i ka pala, a loaʻa i nā kala like ʻole. Ke hoʻohālikelike ʻia me nā puka a me nā puka makani alumini, ʻoi aku ka nui o nā pono a ua lilo mālie i mea punahele hou ma ka mākeke.
3. Hoʻopili ʻia o ka ʻupena uea a me ke kaula
Ua hoʻomaikaʻi ka hoʻohui ʻana o CPE i ka hana puhi cathodic, ka hana anti-aging a me nā waiwai kino a me nā mechanical o nā ʻūpā uea a me nā kaula. I ka manawa like, hōʻike pū nā mea ʻōwili uea a me nā kaula i hana nui ʻia me CPE i ka hana maikaʻi loa.
4. Hana ʻana i nā hose laholio a me nā kapuaʻi kāmaʻa
Hiki i ka CPE ke hana i nā hose e kū i ka ʻaila, ka waikawa, ke kūlou ʻana, ka ozone, a me ka Freon, a kūpono hoʻi no ka hana ʻana i nā hose hydraulic, nā hose cooler, nā hose wahie, a me nā mea hou aku. I ka manawa like, hōʻike pū ka ʻili pipi hoʻopunipuni i hana ʻia me CPE ma ke kino nui i ka hana maikaʻi loa.
