Hehee a me ka hoohana ana i ka UHMWPE Skived Film

ʻO ka UHMW Polyethylene Film he kiʻekiʻe loa ka pale ʻana i ka abrasion, ʻoi aku ka nui o ke kūpaʻa abrasion o ke kila.Hoʻohui pū ʻia me ke kūpaʻa kemika ākea a me ka coefficient haʻahaʻa o ka friction e lilo ai ʻo UHMW i mea ʻenehana loea loa no nā noi lawelawe koʻikoʻi.Paheʻe e like me ka polymer® Fluoropolymer, akā ʻoi loa ka abrasion a me ka pale ʻaʻahu.ʻO ka UHMW Polymers ka awelika kaumaha molekala he 10 manawa ma mua o nā resins polyethylene kiʻekiʻe maʻamau.Hāʻawi ke kaumaha molekala kiʻekiʻe i ka UHMW Polymers i kāna hui like ʻana o nā hiʻohiʻona.

Ua aʻo ʻia ke kiʻiʻoniʻoni skived kalepa o ultra-high molecular-weight polyethylene (UHMWPE) me ke kiʻekiʻe uniaxial orientation1 i ka wā o ka hoʻoheheʻe ʻana a me ka crystallisation me ka hoʻonā manawa o 30 s i mea e ʻike ai i nā mīkini crystallisation.

Ua ʻike ʻia ka hana ʻana o ka crystallization isotropic i ka wā e wela ai ka heheʻe i 140◦C a i ʻole.Hiki mai ka crystallization, inā mālama ʻia ka heheʻe ma 138◦C a ma lalo paha.He 136◦C ka wela o ka hoohehee annealing.Ma keia wela, ua holoi loa ia ka nanostructure semicrystalline o ke kii kumu, aka, ua malamaia ka hoomanao ana o ka hehee.Eia kekahi, ʻaʻole hiki ke hoʻomaka i ka crystallization isothermal ma kahi mahana o 110◦C a ʻoi aʻe.Ma kahi mahana o 105◦C hoʻomaka ka crystallization ma hope o 2.5 min.Ke ulu nei nā Lamellae me ka emi mālie o ka mānoanoa i loko o kahi manawa isothermal o 20 min.

I loko o kēia ʻano crystallization non-isothermal (ka hoʻoluʻu ʻana: 20◦C/min) ua hoʻokumu ʻia nā poloka liʻiliʻi crystalline me ka hoʻopili ʻana i nā hoalauna.No laila, ua like ka hana crystallization me nā mea i loaʻa me nā mea polyethylene ʻē aʻe me ka nui o ke kaulahao entanglement density kiʻekiʻe i aʻo mua ʻia, koe wale nō ka undercooling nui i koi ʻia no ka hoʻomaka ʻana o ka crystallization isothermal.

Ua hana ʻia ka ʻikepili o ka ʻikepili ma ke ākea maoli ma o ka CDF multidimensional.I ka wā o ka hoʻoheheʻe ʻana o ka mea, e mau ana ka mānoanoa awelika o nā papa crystalline (27 nm), ʻoiai ke piʻi ikaika nei ka lōʻihi mai 60 nm a 140 nm.No ka hōʻike ʻana o ka hōʻike ʻana ʻoiai ʻo ka nanostructure kumu i hoʻomalu ʻia e nā correlations e pili ana i nā hoalauna, ʻo ia wale nō ke ʻano o ka piʻi ʻana o ka lamella ma ke ʻano he hana o ka mamao i kona mau hoalauna.ʻOiai ke hōʻike nei ka hale kumu i nā lamellae lōʻihi, ʻaʻole i ʻoi aku ka laulā o nā kikowaena recrystallised ma mua o ka mamao ma waena o lākou ma ke kuhikuhi fiber s3.

Hoʻopili ʻia nā noi i ka laina o ka conveyor, nā ala alakaʻi, nā laina chute, nā alakaʻi kaulahao, nā huki huki a me ka hoʻohaʻahaʻa leo.ʻOi aku ka maikaʻi o ka abrasion a me ka pale ʻana i ke kapa.
