1. kiʻekiʻe loa i ka lole pale
ʻOi aku ka nui o ka paona molecular tube kiʻekiʻe a ʻoi aku ma mua o 2 miliona, ʻoi aku ka liʻiliʻi o ka helu ʻaʻahu, e hāʻawi ana i ke kūʻē kiʻekiʻe loa i ka friction sliding.He 6.6 mau manawa kiʻekiʻe ma mua o ke kila kila maʻamau a he 27.3 mau manawa kiʻekiʻe ma mua o ke kila kila.He 17.9 mau manawa o ka resin phenolic, 6 manawa o ka nylon, 4 mau manawa o ka polyethylene, hoʻomaikaʻi nui i ke ola lawelawe o ka pipeline.
2. kiʻekiʻe hopena kū'ē
ʻO ka waiwai paʻakikī o ka uHMW-pipeline ka mea kiʻekiʻe loa ma waena o nā plastik ʻenekinia e kū nei.Nui nā mea e pohā, haki, haki a i ʻole hoʻoluhi koʻikoʻi ma lalo o ka hopena pahū nui.ʻO kēia huahana e like me ka maʻamau GB1843, ʻo ka cantilever beam impact test no ka loaʻa ʻole o ka pōʻino, hiki ke kū i ka hopena ikaika o waho, overload internal, fluctuation pressure.
3. pale ʻana i ka corrosion
ʻO ka Uhmw-pe kahi ʻano o ka hui molecular saturated, no laila ke kiʻekiʻe loa kona kūpaʻa kemika, hiki i ka huahana ke pale aku i ka erosion o nā mea kemika ikaika, ʻoi aku ka nui o ka waika ikaika i ka wela kiʻekiʻe he liʻiliʻi ka corrosion, ma nā alkali ʻē aʻe. ʻaʻohe ʻino.Hiki ke hoʻohana ʻia i loko o ka waika hydrochloric concentrated me ka ʻike ʻana ma lalo o 80%.He paʻa loa ia i loko o ka sulfuric acid me ka hoʻohaʻahaʻa haʻahaʻa ma mua o 75% a me ka waikawa nitric me ka hoʻopaʻa ʻana ma lalo o 20%.
4. maikaʻi iho lubrication
No ka mea, loaʻa i ka pahu UHMWPE nā mea waxy, a maikaʻi loa kāna lubrication ponoʻī.ʻO ke koena friction (196N, 2 hola) he 0.219MN/m wale nō (GB3960).ʻOi aku ka maikaʻi o kāna hana hoʻoheheʻe ʻana ma mua o ke kila lubricated a i ʻole keleawe.ʻOi loa i loko o ke kaiapuni paʻakikī, ka lepo, ka lepo a me nā wahi he nui, ua hōʻike piha ʻia ka hana lubrication maloʻo ponoʻī o ka huahana.ʻAʻole hiki ke neʻe wale, a pale i ka mea hana kūpono mai ka ʻaʻahu a i ʻole ka pilikia.
5. kū hoʻokahi haʻahaʻa haʻahaʻa
ʻO ka paipu polyethylene kaumaha kiʻekiʻe kiʻekiʻe he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a ʻaʻole i hoʻololi ʻia kona pale ʻana i ka hopena a me ke kūpaʻa ʻaʻahu ma lalo o 269 degere Celsius.I kēia manawa ʻo ia wale nō ka ʻenekinia plastic hiki ke hana i nā mahana kokoke i ka ʻole ʻole.I ka manawa like, ʻo ka paipu uHMWPE he ākea ākea wela, hiki ke hana i ka mahana o -269 ℃ a 80 ℃ no ka manawa lōʻihi.
6. ʻAʻole maʻalahi ka hoʻonui
Uhmwpe paipu i maikai ili non-adhesion a kiʻekiʻe paipu hoopau ma muli o kona haʻahaʻa friction coefficient a me ka ole-polarity.ʻO nā mea i loaʻa i kēia manawa ma ke ʻano maʻamau me ka waiwai PH ma luna o 9, akā ʻaʻole i paona ka paipu uHMWPE, he mea koʻikoʻi ia no ka ʻōnaehana hoʻoheheʻe lehu lanahu i nā mea kanu wela.I loko o ka aila ʻaila, ka lepo a me nā paipu kaʻa ʻē aʻe he kūpono loa.
7. ola lōʻihi
He liʻiliʻi nā genes unsaturated ʻo Uhmwpe i kāna kaulahao molekala, a ʻoi aku kona ikaika luhi ma mua o 500,000 mau manawa.Loaʻa iā ia ka ʻoi aku ka maikaʻi o ke koʻikoʻi a me ke koʻikoʻi kaiapuni.ʻO 4000H, ʻoi aku ma mua o 2 mau manawa o PE100, kanu ʻia no 50 mau makahiki a i ʻole, hiki ke mālama ʻia ma mua o 70% o nā waiwai mechanical.
8. Hoʻokomo maʻalahi
Ultra high molecular weight polyethylene (UHMW—-PE) paipu wae lōʻihi like hoʻokahi wale nō ka walu o ke kila paipu kaumaha, no laila, i ka hoʻouka a unloading, halihali, hoʻouka i oi oluolu, a hiki ke hoemi i ka hana ikaika o na limahana, UHMW-PE. ʻO ka paipu he ikaika anti-kahiko, 50 mau makahiki ʻaʻole maʻalahi i ka ʻelemakule.ʻAʻole pili i ke kūkulu ʻia ʻana o ka honua, a i ʻole ke kanu ʻia ma lalo o ka lepo.Inā hiki ke hoʻokomo ʻia ka hoʻohui ʻana a i ʻole ka flange, palekana, hilinaʻi, wikiwiki a maʻalahi, ʻaʻohe corrosion, hana a me ka ho'ōla hana, hōʻike piha i ka hoʻohana ʻana i ka uHMWPE pipeline "ho'ōla ikehu, mālama kaiapuni, hoʻokele waiwai a maikaʻi".
9. Nā hiʻohiʻona ʻē aʻe
ʻO ka paipu polyethylene paona kiʻekiʻe kiʻekiʻe a me ka hoʻoheheʻe ʻana i ka ikehu, ka leo absorption, anti-static, hiki ke pale uila, ʻaʻole ka hoʻoheheʻe wai, ka umekaumaha māmā, ka mīkini maʻalahi, ke kala a me nā ʻano koʻikoʻi ʻē aʻe.
