He aha ka fiber aniani?

He nui nā pono o ka fiber aniani e like me ka ikaika kiʻekiʻe a me ke kaumaha māmā, ke kūpaʻa i ka pala, ke kūpaʻa wela kiʻekiʻe, ka hana insulation uila maikaʻi, a pēlā aku. ʻO ia kekahi o nā mea maka i hoʻohana pinepine ʻia no nā mea i hui pū ʻia. I ka manawa like, ʻo Kina nō hoʻi ka mea hana nui loa o ka fiber aniani ma ka honua.

1. He aha ka fiberaniani?

ʻO ka fiber aniani kahi mea inorganic non-metallic me ka hana maikaʻi loa, he mineral kūlohelohe me ka silica ma ke ʻano he mea maka nui, hoʻohui i nā mea maka mineral oxide metala kikoʻī, hui like ʻia, hoʻoheheʻe ʻia ma nā mahana kiʻekiʻe, kahe wai aniani i hoʻoheheʻe ʻia ma o ke kahe ʻana o ka funnel, ke kuleana o ka ikaika umekaumaha huki wikiwiki kiʻekiʻe e huki ʻia a hoʻomaʻalili koke ʻia a hoʻōla ʻia i loko o kahi fiber hoʻomau maikaʻi loa.

ʻO ke anawaena o ka monofilament fiber aniani mai kekahi mau microns a ʻoi aku ma mua o iwakālua microns, like me ka lauoho o 1/20-1/5, ua haku ʻia kēlā me kēia pūʻolo o nā fibers me nā haneli a i ʻole nā ​​​​tausani o nā monofilaments.

ʻO nā waiwai kumu o ke aniani fiber: ʻO ke ʻano o kahi ʻili cylindrical laumania, ʻo ka ʻāpana kea he pōʻai piha, ʻo ka ʻāpana kea poepoe e kū i ka hiki ke ukana; he liʻiliʻi ke kinoea a me ka wai ma o ke kū'ē ʻana, akā he laumania ka ʻili i liʻiliʻi ai ka ikaika paʻa o ke fiber, ʻaʻole kūpono i ka hui pū ʻana me ka resin; ʻo ka nui o ka density ma 2.50-2.70 g/cm3, ma muli nui o ka haku mele aniani; ʻoi aku ka ikaika o ka tensile ma mua o nā olonā kūlohelohe ʻē aʻe, ʻoi aku ka kiʻekiʻe o nā olonā synthetic; nā mea palupalu, he liʻiliʻi loa ka elongation i ka haki ʻana. Maikaʻi ke kū'ē ʻana i ka wai a me ka waikawa, ʻoiai he haʻahaʻa ke kū'ē ʻana i ka alkali.

2.Hoʻokaʻawale ʻana o ke aniani fiber

Mai ka hoʻokaʻawale ʻana o ka lōʻihi, hiki ke hoʻokaʻawale ʻia i loko o ke aniani hoʻomau, ke aniani pōkole (ke aniani paʻa) a me ke aniani lōʻihi (LFT).

Mai ka ʻike o ka metala alkali hiki ke hoʻokaʻawale ʻia i ka alkali-free, haʻahaʻa, waena a me ke kiʻekiʻe, maʻamau i hoʻololi ʻia me ka alkali-free, ʻo ia hoʻi, ka fiber aniani E, ʻo ka hoʻololi kūloko i hoʻohana nui ʻia ka fiber aniani E.

3.He aha ka mea hiki ke hoʻohana ʻia ai ke fiber aniani

ʻO ka fiber aniani he ikaika tensile kiʻekiʻe, elasticity kiʻekiʻe, non-flammability, ke kūpaʻa kemika, haʻahaʻa ka omo wai, hana hana maikaʻi a me nā ʻano maikaʻi ʻē aʻe, maʻamau e like me ka mea hui i nā mea hoʻoikaika, nā mea hoʻomehana uila a me nā mea hoʻomehana, substrate kaapuni, a pēlā aku, i hoʻohana nui ʻia ma nā ʻano like ʻole.

Ua māhele ʻia ke aniani haole i ʻehā mau māhele e like me ka hoʻohana ʻana i ka huahana: nā mea hoʻoikaika no nā plastics thermosetting, nā mea hoʻoikaika aniani no nā thermoplastics, nā mea hoʻoikaika gypsum sima, a me nā mea lole aniani, nona nā mea hoʻoikaika he 70-75% a me nā mea lole aniani he 25-30%. Mai ke koi ma lalo, ʻo ke kahua hana he 38% (me ka pipeline, desalination, hoʻomehana hale a me ka pale wai, mālama wai, a pēlā aku), ʻo ka halihali he 27-28% (moku, kaʻa, kaʻaahi wikiwiki, a pēlā aku) a ʻo ka uila he 17%.

I ka hōʻuluʻulu ʻana, ʻo nā wahi hoʻohana o ka fiber aniani e pili ana i ka halihali, nā mea kūkulu hale, ka ʻoihana uila, ka ʻoihana mīkini, ka ʻoihana petrochemical, ka leʻaleʻa a me ka moʻomeheu, a me ka ʻenehana pale aupuni.
