Hoʻomākaukau ʻia ka pepa Aramid ma ka hui ʻana i nā fibers precipitated aramid a me nā fibers pōkole aramid no ka uhi ʻana.

No ka laʻana, hiki ke hoʻohana ʻia kēia mau ʻano: ma hope o ka hui ʻana o ka aramid precipitated fibers i ʻōlelo ʻia ma mua a me ka aramid short fibers, nā aramid precipitated fibers a me nā aramid short fibers e hoʻopuehu ʻia a hui ʻia i loko o kahi ʻano wai me ka hoʻohana ʻana i ke ala kahe ea, a laila. hoʻokuʻu ʻia ma luna o kahi kino kākoʻo permeable wai (e like me ka mesh a i ʻole ke kāʻei) e hana i kahi pepa, a ʻoi aku ke ʻano o ka wehe ʻana i ka wai a me ka maloʻo. ʻO ka mea i kapa ʻia ʻo ka hana ʻana i ka wai, e hoʻohana ana i ka wai ma ke ʻano he ʻano.

ʻO ke kaʻina hana o ka pepa aramid

ʻO ke kaʻina hana hoʻoheheʻe ʻana o nā fila aramid:

Polymerization: I ka pae mua, ua wili ʻia nā fiber aramid i loko o nā pauka polymer paʻa. Loaʻa i kēia mea nā waiwai wela a me nā mea kemika o nā fila para aramid. Eia naʻe, ʻaʻole i loaʻa iā ia nā mea hoʻoikaika o ka yarn a i ʻole ka pulp. Hiki ke hoʻohana ʻia kēia pauka maikaʻi e hoʻomaikaʻi i nā waiwai o nā ʻāpana plastic.

ʻO ka milo: Ma ka lua o ka pae o nā aramid fibers, ua hoʻoheheʻe ʻia ka polymer i loko o ka waikawa sulfuric e hana ai i ka wai aniani. Ma hope iho, ua wili ʻia ka hopena i loko o nā filament maikaʻi, kēlā me kēia me ke anawaena o 12 μ M. ʻO ke ʻano o ka siliki he 100% subcrystalline, me nā kaulahao molekala e like me ke axis fiber. Hāʻawi kēia hāʻawi kiʻekiʻe kiʻekiʻe i ke filament Twaron i nā hiʻohiʻona maikaʻi loa.

ʻO ka pulupulu pōkole: ʻO ka fiber pōkole artificial a i ʻole ka ʻoki ʻoki pōkole, i hana ʻia ma ka wili ʻana i ke kaula a laila mālama ʻia me kahi mea hoʻopau. Ma hope o ka maloʻo ʻana, ʻokiʻoki i nā fibers i nā lōʻihi i hoʻopaʻa ʻia a laila pūʻulu iā lākou.

Milo i loko o ka pulp: No ka hana ʻana i ka pulp, ʻoki mua nā fila aramid i ke kaula a laila hoʻokuʻu i ka wai no ka mālama ʻana i ka fibrosis. A laila hoʻopili pololei ʻia a kūʻai ʻia ma ke ʻano he pulu pulu, a i ʻole dehydrated a maloʻo e like me ka pulp maloʻo no ke kūʻai aku.
