Palekana Mua: Pehea e wehewehe hou ai ka UHMWPE Fiber i ka pale ʻoki i nā mīkina lima ʻoihana

I ka hana ʻoihana hou, ka hana metala, ka ʻākoakoa kaʻa, a me ka hana ʻana i ke aniani kaumaha, ʻo nā ʻeha lima kekahi o nā pōʻino wahi hana pinepine a pipiʻi hoʻi. No nā makahiki he ʻumi, ua hilinaʻi nā luna palekana i ka ʻili kaumaha, nā hui pulupulu ʻāwili, a i ʻole nā ​​​​​​mea hana aramid hanauna mua e hāʻawi i ka pale kumu e kūʻē i nā ʻoiʻoi, nā ʻūlū metala, a me nā mīkini ʻokiʻoki. ʻOiai ua hāʻawi kēia mau mea i kahi kumu o ka pale ʻana, ua hōʻike lākou i nā kālepa nui ma ke kaumaha, ka nui kino, a me ka dexterity lima.

I kēia lā, ke hoʻololi nei kahi hoʻololi kūkulu i ka ʻoihana lako pale pilikino (PPE). ʻO ka hoʻohana nui ʻana o ka fiber Ultra-High Molecular Weight Polyethylene (UHMWPE) ke kākau hou nei i nā kūlana o ka pale lima ʻoihana. Me ka hoʻohui ʻana i ka ikaika tensile koʻikoʻi me ke kaumaha haʻahaʻa, hiki i ka fiber UHMWPE i nā mea hana mīkina lima ke hana i ka PPE māmā a maʻalahi hoʻi e hoʻokō ai i ke kūpaʻa ʻoki maikaʻi loa me ka ʻole o ka mōhai ʻana i ka ʻoluʻolu o ka mea hoʻohana a i ʻole ka mana motor.

Ke noiʻi nei kēia loiloi loea i ka ʻepekema mea ma hope o ka fiber UHMWPE, pehea e wehewehe hou ai i nā kūlana kū'ē i ka ʻoki honua, a no ke aha i lilo ai ia i mea koho no nā mīkina lima palekana kiʻekiʻe.

ʻO ka Papahana Molekala: He aha ka mea e kū'ē ai i ka ʻoki ʻana o ka fiber UHMWPE?

I mea e maopopo ai ke kumu e hāʻawi ai ka fiber UHMWPE i kēlā ʻano pale ʻoki kiʻekiʻe, pono mākou e nānā i kona ʻano molekala. ʻAʻole e like me ka polyethylene maʻamau, nona nā loulou polymer kaulahao pōkole, ʻo UHMWPE nā kaulahao lōʻihi loa o ka ethylene polymerized. Loaʻa i kēia mau kaulahao molekala kahi nui molekala ma waena o 3.5 a me 7.5 miliona mau ʻāpana nui atomika.

I ka wā o ke kaʻina hana hana gel wili kūikawā, ua hoʻonohonoho ʻia kēia mau kaulahao polymer nui ma ke axis longitudinal o ke fiber. ʻO kēia kiʻekiʻe o ke kuhikuhi a me ka crystallization e hana i ka alignment like maikaʻi loa, e ʻae ana i ke kaumaha kino o waho e hoʻolaha like ma ke ʻano molekala holoʻokoʻa. Ma ke kumu kaumaha-no-kaumaha, ʻo kēia alignment molekala e hana i ka fiber UHMWPE a hiki i 15 mau manawa ikaika ma mua o ke kila kūkulu a ʻoi aku ka paʻa i ka abrasion a me nā ikaika hopena ma mua o nā fiber aramid maʻamau.

Nā ʻano hana o kahi pōʻino ʻoki:Ke kuʻi ka pahi ʻoi a i ʻole ka lihi metala i kahi mīkina lima i ulana ʻia mai ka fiber UHMWPE, pale ka ikaika tensile longitudinal kiʻekiʻe i ka pahi mai ka hopu ʻana a me ka ʻoki ʻana ma o nā filaments pākahi. Akā, ʻo ka ʻili pahee a haʻahaʻa o ka polymer e ʻae i ka lihi ʻoi e holo ma waena o ka ulana, e hoʻopuehu ana i ka ikehu mechanical ma kahi ākea ma mua o ka hoʻoikaika ʻana i kahi kiko hoʻokahi o ka hāʻule ʻana.

Ke Hoʻākāka Hou ʻana i nā Kūlana Honua: ANSI a me EN388 Nā ʻIke Hana

Loiloi ka ʻāpana palekana ʻoihana i ka hana o nā mīkina lima ma muli o ʻelua mau ʻōnaehana hoʻāʻo honua nui: ke kūlana ʻAmelika ʻĀkau ANSI/ISEA 105 a me ka ʻōnaehana ʻEulopa EN 388. Hoʻohālikelike nā kūlana ʻelua i ka nui o ka ikaika e pono ai no kahi pahi mīkini e ʻoki i kahi lole laʻana ma lalo o nā kūlana i kāohi ʻia.

I ka wā ma mua, ʻo ka hoʻokō ʻana i nā helu kiʻekiʻe (e like me ANSI Cut Level A4 a hiki i A6, a i ʻole EN388 Levels D a me E) pono nā papa mānoanoa a nui o ka lole ulana, i hoʻoikaika pinepine ʻia me ka fiberglass brittle a i ʻole nā ​​​​​​kiko kila kaumaha. Hoʻonāukiuki pinepine kēia mau hoʻonohonoho hui i ka ʻili a hoʻoulu i ka luhi o ka lima, e alakaʻi ana i nā limahana e wehe i ko lākou mau mīkina lima a hoʻonui i ko lākou pilikia o ka ʻeha.

Ua hoʻololi ke olonā UHMWPE i kēia ʻano. Ma ka hoʻohana ʻana i nā olonā UHMWPE denier kiʻekiʻe, hiki i nā mea hana ke hoʻokō i nā helu ʻoki ANSI kiʻekiʻe me nā ulana hoʻokahi papa, kiʻekiʻe-gauge (e like me nā pūpū 15-gauge a i ʻole 18-gauge). Hāʻawi kēia i kekahi mau pono hana koʻikoʻi:

Hoʻonui ʻia ka ʻike Tactile:Hiki i nā limahana ke lawelawe i nā mea hoʻopaʻa liʻiliʻi, nā micro-electronics, a me nā mea hana pololei me ka wehe ʻole ʻana i ko lākou mau mīkina lima palekana.

Luhi o ka lima haʻahaʻa:ʻO ka maʻalahi o ka UHMWPE e ʻae i ka mīkina lima e kūlike maoli i ke ʻano o ka lima, e hōʻemi ana i ke kū'ē i ka wā o nā neʻe paʻa hou.

Hoʻomaikaʻi ʻia ka ʻoluʻolu wela:Loaʻa i ka UHMWPE ke alakaʻi wela kiʻekiʻe, e ʻae ana i ka wela mai ka lima e hoʻopuehu koke. Mālama kēia i nā lima i ke anuanu a ʻoluʻolu hoʻi i ka wā o nā hana lōʻihi ke hoʻohālikelike ʻia me nā synthetics e hoʻopaʻa ana i ka wela.

Hoʻohālikelike Mea Piha: UHMWPE vs. Nā ʻOniona ʻē aʻe

Ka Lōʻihi o ka Hana a me ka Pono o ke Kumukūʻai

Ma waho aʻe o kona mau pono palekana koke, makemake nui nā luna palekana ʻoihana i ka fiber UHMWPE no kona pono kālā lōʻihi. I nā wahi ʻoihana kaumaha, ua hōʻike ʻia nā mikina lima hana i nā aila, nā ʻaila, nā mea hoʻoheheʻe, a me nā pōʻaiapuni holoi pinepine.

Hoʻopōʻino ka nui o nā mīkina lima i hana ʻia me ka aramid i ka wā e hōʻike ʻia ai i ka makū a me nā mea holoi ʻoihana, e nalowale ana kahi pakeneka o ko lākou mau waiwai kūʻē i ka ʻoki me kēlā me kēia kaʻina holoi lole. I ka hoʻohālikelike ʻana, he inert kemika ka fiber UHMWPE a hydrophobic loa. ʻAʻole ia e omo i ka wai, nā aila, a i ʻole nā ​​​​​​mea hoʻomaʻemaʻe kemika. Hiki ke holoi pinepine ʻia nā mīkina lima i hana ʻia mai ka fiber UHMWPE premium me ka ʻole o ka emi ʻana, ka nalowale ʻana o ka ikaika tensile, a i ʻole ka hoʻopilikia ʻana i kā lākou helu ʻoki ANSI/EN388. Hoʻemi kēia ola hana i hoʻolōʻihi ʻia i ke alapine o nā pani, e hoʻohaʻahaʻa ana i nā kumukūʻai kūʻai PPE holoʻokoʻa no nā ʻoihana ʻoihana nui.

No ke aha e koho ai i nā hoʻonā fiber HUIDUN UHMWPE?

Ma ke ʻano he mea hoʻomohala alakaʻi o nā polymers loea hana kiʻekiʻe,ʻO Huidun UHMWPE (https://www.huidunuhmwpe.com/) hana i nā olonā UHMWPE ʻoihana kiʻekiʻe i hana ʻia no nā noi mīkina lima palekana hou. Ma ka hoʻohana ʻana i ka ʻenehana gel-spinning holomua a me ka hoʻokele maikaʻi koʻikoʻi, hana ʻo Huidun i nā olonā i hōʻailona ʻia e ka kaohi denier kūlike, nā waiwai tensile kūikawā, a me ke kūpaʻa ulana maikaʻi loa.

Inā ʻoe e hoʻomohala nei i nā mīkina lima ʻākoakoa pololei 18-gauge o ka hanauna hou a i ʻole nā ​​​​​​ʻaʻahu palekana composite kaumaha no nā wili kila, hāʻawi ʻo Huidun i ke kumu waiwai maka e pono ai e ʻoi aku ma mua o nā kūlana pale ʻoki paʻa. E hui pū me Huidun e hoʻokiʻekiʻe i kāu mau laina huahana PPE, e hōʻoia i ka mālama ʻana i nā lula palekana honua, a hāʻawi i ka pale lima hilinaʻi no nā limahana ʻoihana koi ma ka honua holoʻokoʻa.
