Introduction to UHMWPE fiber maloʻo a pulu kaʻina hana

ʻO ka mea hoʻoheheʻe i hoʻohana ʻia no ka wili gel maloʻo ʻo ia ka decalin me ka helu hoʻolapalapa haʻahaʻa, ka volatility kiʻekiʻe a me ka solubility maikaʻi no UHMWPE.Hoʻohui ʻia ʻo UHMWPE a me ka decalin i loko o kahi hoʻonā me ka manaʻo ʻaʻole i ʻoi aku ma mua o 10% i loko o kahi extruder māhoe-screw, a laila hoʻokuʻu ʻia ma o ka spinneret e komo i kahi ʻāpana nitrogen wela e wehe i nā mea hoʻoheheʻe.Ma hope o ka hoʻoluʻu ʻana, hoʻokumu ʻia nā filament gel maloʻo, a laila hana ʻia nā fibers UHMWPE e nā pae kiʻekiʻe kiʻekiʻe wela wela.He mea paʻakikī ke kaʻina hana wili gel maloʻo a koi i ka sila kiʻekiʻe o ka ʻōnaehana hoʻihoʻi, akā ʻo kāna mau mea maikaʻi e waiho nei i:

1. ʻO ke kaʻina hana pōkole, ʻoi aku ka nui o ka huahana a me ke kumu kūʻai haʻahaʻa.

2. Hiki ke hoʻohana hou ʻia ka solvent, ʻoi aku ka maikaʻi o ka mālama ʻana i ke kaiapuni.

3. Ma lalo o nā kūlana ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka crystallinity o nā fibers i hoʻomākaukau ʻia e ke ʻano maloʻo, nā waiwai mechanical, ʻoi aku ka kiʻekiʻe o ka fiber a me ka ʻoi aku ka maikaʻi o ka wela.

4. He maikai luster, palupalu manao a me ka haʻahaʻa'ūheheʻe koena, a ua kūpono no ka lapaau a me ka home textile mahina.I kēia manawa, ʻo nā mea hana nui ʻo DSM Company o Netherlands, TOYOBO Company o Iapana, a me Yizheng Chemical Fiber Company o Sinopec.

Ma ke kaʻina hana wili pulu, hoʻohana ʻia ka ʻaila keʻokeʻo me kahi kiʻekiʻe o ka paila a me ka volatility haʻahaʻa e like me ka solvent.Hoʻoheheʻe ʻia ka pauka Ultrahigh i loko o ka aila keʻokeʻo e hana i ka hopena wili.A laila, hoʻokuʻu ʻia i loko o kahi filament wai e nā ʻāpana wili.A laila, hoʻoluʻu ʻia i loko o kahi ʻauʻau wai e hana i kahi filament gel.Wehe ʻia ka filament gel, maloʻo a hoʻopau ʻia e hana i kahi precursor unstretched, a laila ua wela ia no nā manawa he nui e hana i kahi fiber paʻa.ʻOi aku ka paʻakikī o ka ʻenehana kaʻina wai a koi aku i nā mea hana liʻiliʻi.I kēia manawa, hoʻohana ka hapa nui o nā ʻoihana kūloko i ke kaʻina wili pulu, hiki ke hana i nā huahana pūʻali koa a me nā kīwila me nā helu denier ʻokoʻa a me nā ikaika.Eia nō naʻe, ʻo ka manaʻo o ka noiʻi ʻana i ke ala kaʻina wai i kēia manawa ʻo ia ka hoʻomaikaʻi ʻana i ke ala kaʻina hana, e hoʻomaikaʻi hou i nā waiwai mechanical, kūpaʻa a me ka hana o ka fiber, e kālele ana i nā huahana waena a haʻahaʻa.I kēia manawa, ʻo nā mea hana nui ʻo Honeywell Company ma United States, Beijing Tongyizhong Company ma Kina, a me Nantong Jiujiujiu Company.
