Hōʻuluʻulu manaʻo
I ka hapalua o ke kenekulia i hala iho nei, ua hoʻohana nui ʻia nā mea hoʻohuihui fiber-reinforced ma muli o ko lākou mau waiwai maikaʻi loa, a ʻo ke kuleana koʻikoʻi o ka hoʻoikaika ʻana i nā fibers i nā mea i hoʻohuihui ʻia. Mai ka hiki ana mai omea hoohuihui, ua hoʻololi ʻia ka hoʻoikaika ʻana i nā fibers mai nā fiber maoli i nā fiber synthetic.
I kēia manawa, ʻo nā fibers hoʻoikaika maʻamau e pili ana i nā fiber glass, nā fiber aramid,kalapona kalapona, etc. E hoʻolauna kēia ʻatikala i nā ʻano a me nā hoʻohana ʻana o nā fiber aniani no ka hoʻoikaika ʻana i ka hui.
He ahaaniani uila?
Hoʻohana nui ʻia nā fiber Glass ma muli o ko lākou kumukūʻai a me nā waiwai maikaʻi, ʻoi loa i ka ʻoihana composites. I ka hoʻomaka ʻana o ke kenekulia 18, ua ʻike ka poʻe ʻEulopa e hiki ke wili ʻia ke aniani i mau fiber no ka ulana ʻana. Ua loaʻa mua i ka pahu kupapaʻu o ka Emepera Farani Napoleon nā lole hoʻonaninani i hana ʻia me ka fiberglass. Loaʻa nā filament a me nā pulu pōkole a i ʻole nā flocs i nā pulu aniani. Hoʻohana pinepine ʻia nā filament aniani i nā mea i hoʻohui ʻia, nā huahana pāpaʻi, nā kāʻei conveyor, tarpaulins, a me nā mea ʻē aʻe.
ʻO nā hiʻohiʻona kino a me nā mechanical maikaʻi o ke aniani fiber, maʻalahi o ka hana ʻana, a me ke kumu kūʻai haʻahaʻa i hoʻohālikelike ʻia me ka fiber carbon i mea i koho ʻia no nā noi composite kiʻekiʻe. Hoʻokumu ʻia nā pulu aniani me nā oxides o ke silica. Loaʻa i nā pulu aniani nā waiwai mechanical maikaʻi loa e like me ka liʻiliʻi liʻiliʻi, ikaika kiʻekiʻe, haʻahaʻa ʻoʻoleʻa a me ke kaumaha māmā.
ʻO nā polymers i hoʻoikaika ʻia i ke aniani fiber he ʻano nui o nā ʻano ʻano aniani like ʻole, e like me nā fiber longitudinal, nā ʻoki ʻokiʻoki, nā moena ulana, amoena mānoanoa ʻoki ʻia , a hoʻohana ʻia e hoʻomaikaʻi i nā waiwai mechanical a tribological o nā polymer composites. Hiki i nā pulu aniani ke hoʻokō i nā lakio hiʻohiʻona kiʻekiʻe, akā hiki i ka brittleness ke kumu i ka haki ʻana o nā fiber i ka wā e hana ai.
Hōʻike ka papa ma lalo nei i nā ʻano like ʻole o nā fiber aniani a me nā haku mele.
Na Waiwai Kinohi
ʻO nā hiʻohiʻona nui o ka fiber glass e pili ana i kēia mau mea:
ʻAʻole maʻalahi ka lawe ʻana i ka wai: ʻO ka pulupulu aniani ka mea pale i ka wai a ʻaʻole kūpono i nā lole, no ka mea, ʻaʻole e komo ka hou, e pulu ai ka mea nona; no ka mea, ʻaʻole pili ka mea i ka wai, ʻaʻole ia e emi.
In-elasticity: Ma muli o ka nele o ka elasticity, ʻaʻohe liʻiliʻi o ka lole a me ka hoʻihoʻi hou ʻana. No laila, pono lākou i kahi lāʻau lapaʻau e pale aku i ka wrinkling.
Ka ikaika kiʻekiʻe: He ikaika loa ka Fiberglass, aneane like ka ikaika me Kevlar. Eia nō naʻe, i ka wā e paʻi ai nā ʻili i kekahi i kekahi, ua haki lākou a lilo ka lole i kahi ʻano haʻalulu.
Hoʻokaʻawale:Ma ke ʻano pōkole pōkole, ʻo ka fiberglass kahi insulator maikaʻi loa.
Hiki ke hoʻopaʻa ʻia:Hoʻopili maikaʻi nā fibers, no laila kūpono lākou no nā pale.
Palena wela:ʻO nā fibers aniani ke kūpaʻa wela kiʻekiʻe, hiki ke kūpaʻa i nā mahana a hiki i 315 ° C, ʻaʻole i hoʻopilikia ʻia e ka lā, bleach, bacteria, mold, insects or alkalis.
Pilikia: Hoʻopili ʻia nā fiber aniani e ka waika hydrofluoric a me ka waika phosphoric wela. No ka mea he huahana aniani ka fiber, pono e mālama pono ʻia kekahi mau kīʻaha maka, e like me nā mea hoʻokaʻawale hale, no ka mea he palupalu nā hopena a hiki ke hou i ka ʻili, no laila pono e hoʻohana ʻia nā mīkina lima i ka wā e lawelawe ai i ka fiberglass.
Hōʻike ʻia nā waiwai kino a me nā mīkini o nā kīʻaha aniani kalepa ma ka papa ma lalo.
Ke Kaʻina Hana Fiber Glass
ʻO ka fiber Glass kahi fiber non-metallic i hoʻohana nui ʻia i kēia manawa ma ke ʻano he mea ʻenehana. ʻO ka mea maʻamau, ʻo nā mea kumu kumu o ka fiber aniani e loaʻa i nā ʻano minerala kūlohelohe a me nā kemika i hana ʻia e ke kanaka, ʻo nā mea nui he one silica, limestone a me ka lehu soda.
Hana ʻia ke one silica ma ke aniani mua, ʻoiai ʻo ka soda a me ka limestone e kōkua i ka hoʻohaʻahaʻa ʻana i ka wela hoʻoheheʻe. ʻO ka haʻahaʻa haʻahaʻa o ka hoʻonui wela i hui pū ʻia me ka haʻahaʻa haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me ka asbestos a me nā fiber organik e hana i ka fiberglass i mea paʻa paʻa e hoʻopau koke i ka wela.
Papa Kaʻina Kaʻina Hana Fiber Glass
Hoʻopuka ʻia nā fibers aniani e ka hoʻoheheʻe pololei ʻana, e pili ana i nā kaʻina hana e like me ka hui ʻana, ka hoʻoheheʻe ʻana, ka milo, ka uhi ʻana, ka maloʻo, a me ka hoʻopili ʻana. ʻO ka pūʻulu ka moku'āina mua o ka hana aniani, kahi i hui maikaʻi ʻia nā mea waiwai, a hānai ʻia ka hui ʻana i loko o ka umu ahi no ka hoʻoheheʻe ʻana ma kahi kiʻekiʻe o 1400 ° C. Ua lawa kēia mahana no ka hoʻololiʻana i ke one a me nā mea'ē aʻe i keʻano hoʻoheheʻe; kahe ka aniani i hooheheeia iloko o ka mea hoomaemae a haule ka mahana i 1370°C.
I ka wā o ka wili ʻana o nā pulu aniani, kahe ka aniani hoʻoheheʻe ʻia ma ka lima lima me nā puka maikaʻi loa. Hoʻomaʻamaʻa ʻia ka pā liner me ka uila a mālama ʻia kona mahana e mālama i ka viscosity mau. Ua hoʻohana ʻia kahi jet wai e hoʻoluʻu i ka filament i kona puka ʻana i ka lima ma kahi mahana o 1204°C.
PapahanaʻO Diagram oʻO GkaikamahineFiberSpaʻi ʻana
Hoʻokomo ʻia ke kahawai extruded o ke aniani hoʻoheheʻe ʻia i loko o nā filament me nā anawaena mai ka 4 μm a 34 μm. Hāʻawi ʻia ka hoʻopaʻapaʻa me ka hoʻohana ʻana i ka winder kiʻekiʻe a huki ʻia ke aniani hoʻoheheʻe ʻia i loko o nā filament. I ka pae hope loa, ua hoʻopili ʻia nā uhi kemika o nā lubricants, binders a me nā mea hoʻohui i nā filament. Kōkua ka lubrication i ka pale ʻana i nā filament mai ka abrasion ke hōʻiliʻili ʻia a ʻeha i loko o nā pūʻolo. Ma hope o ka nui ʻana, hoʻomaloʻo ʻia nā fiber i ka umu; a laila mākaukau nā filament no ka hana hou ʻana i ʻokiʻoki ʻia, nā rovings a i ʻole nā wili.
Noi oʻO GkaikamahineFiber
ʻO ka fiberglass kahi mea ʻaʻole i wela a mālama ʻia ma kahi o 25% o kona ikaika mua ma 540°C. He liʻiliʻi ka hopena o ka hapa nui o nā kemika i nā fiber aniani. ʻAʻole e pohō a ʻino paha ka fiberglass inorganic. Hoʻopili ʻia nā fiber glass e ka waika hydrofluoric, ka waika phosphoric wela a me nā mea alkaline ikaika.
He mea hoʻopololei uila maikaʻi loa ia. Loaʻa i nā lole Fiberglass nā waiwai e like me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ikaika kiʻekiʻe, kūpaʻa wela a me ka mau dielectric haʻahaʻa, e hana ana iā lākou i mea hoʻoikaika maikaʻi no nā papa kaapuni paʻi a me nā varnish insulating.
ʻO ka lākiō kiʻekiʻe o ka ikaika-a-kaumaha o ka fiberglass he mea maikaʻi loa ia no nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kaumaha liʻiliʻi. Ma ke ʻano textile, hiki i kēia ikaika ke unidirectional a i ʻole bidirectional, e ʻae i ka hoʻololi ʻana i ka hoʻolālā a me ke kumukūʻai no ka nui o nā noi i ka mākeke kaʻa, kūkulu kīwila, nā waiwai haʻuki, aerospace, moana, uila, Home a me ka ikehu makani.
Hoʻohana ʻia lākou i ka hana ʻana i nā composites structural, nā papa kaapuni paʻi a me nā huahana kūikawā. ʻO ka hana ʻana o ka fiber aniani makahiki ma kahi o 4.5 miliona tons, a ʻo nā mea hana nui ʻo Kina (60% mākeke), ʻo ʻAmelika Hui Pū ʻIa a me ʻEulopa. (Kumu: Carbon Fiber a me kāna ʻenehana Mea Hana Hana)
