He aha ka fiberglass?

Hoʻohana nui ʻia nā olonā aniani ma muli o ko lākou kumukūʻai kūpono a me nā waiwai maikaʻi, ʻo ia hoʻi ma ka ʻoihana composites. I ka hoʻomaka ʻana o ke kenekulia 18, ua ʻike ka poʻe ʻEulopa e hiki ke milo ʻia ke aniani i loko o nā olonā no ka ulana ʻana. Ua loaʻa mua i ka pahu kupapaʻu o ka Emepera Farani ʻo Napoleon nā lole hoʻonaninani i hana ʻia me ka fiberglass. Loaʻa i nā olonā aniani nā filaments a me nā olonā pōkole a i ʻole flocs. Hoʻohana pinepine ʻia nā filaments aniani i nā mea composite, nā huahana rubber, nā kāʻei conveyor, nā tarpaulins, a me nā mea ʻē aʻe. Hoʻohana nui ʻia nā olonā pōkole i nā moena i ulana ʻole ʻia, nā plastics ʻenekinia a me nā mea composite.

ʻO nā waiwai kino a me nā ʻano mechanical o ka fiber aniani, ka maʻalahi o ka hana ʻana, a me ke kumukūʻai haʻahaʻa i hoʻohālikelike ʻia meʻili kalaponae hoʻolilo iā ia i mea koho no nā noi composite hana kiʻekiʻe. Hana ʻia nā olonā aniani i nā oxides o ka silica. Loaʻa i nā olonā aniani nā waiwai mechanical maikaʻi loa e like me ka emi ʻana o ka palupalu, ka ikaika kiʻekiʻe, ka paʻakikī haʻahaʻa a me ke kaumaha māmā.

ʻO ke olonā aniani ʻO nā polymers i hoʻoikaika ʻia he papa nui o nā ʻano like ʻole o nā olonā aniani, e like me nā olonā longitudinal,nā olonā i ʻoki ʻia, nā moena ulana, a menā moena kaula i ʻoki ʻia, a hoʻohana ʻia e hoʻomaikaʻi i nā waiwai mechanical a me tribological o nā composites polymer. Hiki i nā olonā aniani ke hoʻokō i nā lakio hiʻohiʻona mua kiʻekiʻe, akā hiki i ka brittleness ke hana i nā olonā e haki i ka wā e hana ai.

nā waiwai o ke aniani fiber

ʻO nā ʻano nui o ka fiber aniani e komo pū ana me kēia mau ʻano:

ʻAʻole maʻalahi ke omo i ka wai:ʻO ke olonā anianihe mea pale wai a ʻaʻole kūpono no nā lole, no ka mea, ʻaʻole e omo ʻia ka hou, e hoʻomaʻū ana i ka mea ʻaʻahu; no ka mea, ʻaʻole i hoʻopilikia ʻia ka lole e ka wai, ʻaʻole ia e mimi.

ʻOle ka palupalu: Ma muli o ka nele o ka palupalu, ʻaʻole nui ka hoʻolōʻihi a me ka hoʻōla ʻana o ka lole. No laila, pono lākou i kahi mālama ʻili e pale aku i ka ʻūlū ʻana.

Ikaika Kiʻekiʻe:ʻO ke aniani fiberglass he ikaika loa ia, kokoke like me ke Kevlar. Eia nō naʻe, ke hamo nā olonā kekahi i kekahi, haki lākou a lilo ka lole i ʻano shaggy.

Ka Hoʻokaʻawale ʻana: Ma ke ʻano pōkole o ka fiber, he mea hoʻokaʻawale maikaʻi loa ka fiberglass.

Ka Lole ʻAna: Lole maikaʻi nā olonā, kūpono ia no nā pale.

Ke Kū'ē Wela: Loaʻa i nā olonā aniani ke kūpaʻa wela kiʻekiʻe, hiki ke kū i nā mahana a hiki i 315 ° C, ʻaʻole lākou i hoʻopilikia ʻia e ka lā, ka bleach, ka bacteria, ka ʻōpala, nā pepeke a i ʻole nā ​​​​alkalis.

Hiki ke hoʻopilikia ʻia:Nā olonā aniani ua hoʻopilikia ʻia e ka waikawa hydrofluoric a me ka waikawa phosphoric wela. ʻOiai he huahana aniani ka fiber, pono e mālama pono ʻia kekahi mau olonā aniani maka, e like me nā mea hoʻomehana hale, no ka mea, he palupalu nā wēlau o ka fiber a hiki ke hou i ka ʻili, no laila e pono e ʻaʻahu i nā mīkina lima i ka wā e lawelawe ai i ka fiberglass.

Ka hoʻohana ʻana o ke aniani fiber

ʻO ke aniani fiberglass he mea inorganic ia ʻaʻole e puhi a mālama i kahi 25% o kona ikaika mua ma 540°C. ʻAʻole nui ka hopena o ka hapa nui o nā kemika i nā olonā aniani. ʻAʻole e ʻōpala a palaho paha ka fiberglass inorganic. Hoʻopilikia ʻia nā olonā aniani e ka waikawa hydrofluoric, ka waikawa phosphoric wela a me nā mea alkaline ikaika.

He mea hoʻokaʻawale uila maikaʻi loa ia.Nā lole fiberglass he mau waiwai e like me ka haʻahaʻa o ka omo ʻana o ka makū, ka ikaika kiʻekiʻe, ke kūpaʻa wela a me ka haʻahaʻa dielectric constant, e lilo ana iā lākou i mau mea hoʻoikaika kūpono no nā papa kaapuni i paʻi ʻia a me nā varnish insulating.
