Hoʻohana ka pā UHMWPE i ke ʻano Ziegler type high-efficiency catalyst low-pressure synthesis a hoʻomalu ʻia ma luna o 1.5 a 3 miliona e like me ka makemake.I ka noʻonoʻo ʻana i ka hoʻohaʻahaʻa wela o nā molekala i ka wā o ka hoʻoili ʻana, hiki ke hana ʻia ka polyethylene kiʻekiʻe me ka viscosity awelika molecular ʻoi aku ma mua o 1.7 miliona i nā huahana like ʻole e loaʻa ai ka hana ʻoi aku ka maikaʻi.
Hoʻohana ka pā UHMWPE i ke ʻano Ziegler type high-efficiency catalyst low-pressure synthesis, a hoʻomalu ʻia ma luna o 1.5 a 3 miliona e like me ka makemake.I ka noʻonoʻo ʻana i ka hoʻohaʻahaʻa wela o nā molekala i ka wā o ka hoʻoili ʻana, hiki ke hana ʻia ka polyethylene kiʻekiʻe me ka viscosity awelika molecular ʻoi aku ma mua o 1.7 miliona i nā huahana like ʻole e loaʻa ai ka hana ʻoi aku ka maikaʻi.
1. ʻOi aku ka maikaʻi o ka ʻaʻahu ʻana o ka pā UHMWPE ma waena o nā plastik ʻenekinia o kēia manawa a ʻoi aku ka maikaʻi o ka maka.ʻOi aku ka kiʻekiʻe o ka molekala, ʻoi aku ka paʻa o ka lole, ʻoi aku ma mua o ka nui o nā mea metala (e like me ke kila kalapona, ke kila kila, ke keleawe, etc.).No ka laʻana, loaʻa i nā paipu UHMW-PE ke ola lawelawe o 4-6 mau manawa o nā paipu kila ma lalo o nā kūlana o ka corrosion ikaika a me ka lole kiʻekiʻe, a hoʻonui i ka pono o ka hoʻouna ʻana ma 20%.Hōʻike piha ia i ke kūlana kiʻekiʻe o "ka mālama ʻana i ka ikehu, ka palekana o ke kaiapuni, ka hoʻokele waiwai a me ka hana kiʻekiʻe".
2. Ke kū'ē i ka corrosion: ʻAʻole ia i corroded i ka lye a hiki ke hoʻohana ʻia i ka waika hydrochloric concentrated ma 80 ° C.Loaʻa iā ia ka hana paʻa i ka 75% concentrated sulfuric acid a me 20% nitric acid.He kūpaʻa nō hoʻi i ka wai kai a me nā mea holoi wai.
3. Haʻahaʻa haʻahaʻa haʻahaʻa o ka friction: ʻO ka coefficient o ka friction static he 0.07, a he maikaʻi kāna mau waiwai ponoʻī.He ala kūpono ia, ka hoʻoulu ʻana, ka poloka sliding a me nā mea lining.ʻO ka hoʻohana ʻana i ka pā UHMWPE e like me ka ʻāpana friction o nā mea hana ʻaʻole hiki ke hoʻonui i ke ola pale ʻaʻahu, akā loaʻa pū kekahi i nā hopena hoʻōla.
4. Ke kū'ē i ka hopena: Ke kūlana mua ke kū'ē i ka hopena ma waena o nā plastic.ʻO ka ikaika o waho a i ʻole nā pilikia o loko, he paʻakikī ke haki.ʻO ka ikaika o kona hopena he 10 mau manawa ma mua o ka nylon 66, 20 manawa o ka polyvinyl chloride, a he 8 manawa o ka polytetrafluoroethylene.ʻOi aku ma nā wahi haʻahaʻa haʻahaʻa, hiki i kona ikaika hopena i kahi waiwai kiʻekiʻe, a hiki i kona maʻalahi ke hāʻawi i nā ʻōnaehana kaʻa palekana palekana, hōʻoia hilinaʻi.
