ʻO ke olonā basalt
ʻO ke olonā basalt kahi olonā hoʻomau i huki ʻia mai ka basalt kūlohelohe. He pōhaku basalt ia ma 1450 ℃ ~ 1500 ℃ ma hope o ka hoʻoheheʻe ʻia ʻana, ma o ka platinum-rhodium alloy wire drawing plate leakage wikiwiki e huki ana i hana ʻia me ke olonā hoʻomau. ʻO ke kala o ke olonā basalt kūlohelohe maʻemaʻe he ʻeleʻele maʻamau. ʻO ke olonā basalt kahi ʻano hou o nā mea olonā hana kiʻekiʻe ʻōmaʻomaʻo inorganic e pili ana i ke kaiapuni, i haku ʻia me ka silica, alumina, calcium oxide, magnesium oxide, hao oxide a me titanium dioxide a me nā oxides ʻē aʻe.ʻO ka fiber hoʻomau basaltʻAʻole wale ka ikaika kiʻekiʻe, akā he ʻano waiwai maikaʻi loa hoʻi e like me ka insulation uila, ke kūpaʻa ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe a pēlā aku. Eia kekahi, ua hoʻoholo ke kaʻina hana o ka fiber basalt e hana i ka liʻiliʻi o ka ʻōpala, ka haumia liʻiliʻi i ke kaiapuni, a hiki ke hoʻohaumia pololei ʻia ka huahana i ke kaiapuni ma hope o ka ʻōpala ʻana, me ka ʻole o ka hōʻino, no laila he mea ʻōmaʻomaʻo maoli ia, he mea aloha i ke kaiapuni. Ua hoʻohana nui ʻia nā fibers hoʻomau basalt i nā composites i hoʻoikaika ʻia i ka fiber, nā mea friction, nā mea kūkulu moku, nā mea hoʻokaʻawale wela, ka ʻoihana kaʻa, nā lole kānana wela kiʻekiʻe, a me nā kahua pale.
Nā ʻano
① Nā mea maka lawa
ʻO ka olonā basaltUa hana ʻia ia me ka basalt ore i hoʻoheheʻe ʻia a huki ʻia, a ʻo ka basalt ore ma ka Honua a me ka mahina he mau mālama waiwai maoli nō ia, mai ke kumukūʻai o nā mea maka he haʻahaʻa loa ia.
② Mea pili i ke kaiapuni
He mea kūlohelohe ka basalt ore, ʻaʻohe boron a i ʻole nā ​​​​oxides metala alkali ʻē aʻe i hoʻokuʻu ʻia i ka wā o ke kaʻina hana, no laila ʻaʻohe mea ʻino i hoʻoulu ʻia i loko o ka uahi, ʻaʻole e hoʻohaumia ka lewa. Eia kekahi, he lōʻihi ke ola o ka huahana, no laila he ʻano hou ia o ka mea palekana kaiapuni ʻōmaʻomaʻo me ke kumukūʻai haʻahaʻa, hana kiʻekiʻe a me ka maʻemaʻe kūpono.
③ Ke kūpaʻa kiʻekiʻe o ka mahana a me ka wai
ʻO ka pae mahana hana o ka fiber basalt hoʻomau he 269 ~ 700 ℃ (kahi palupalu o 960 ℃), ʻoiai no ka fiber aniani he 60 ~ 450 ℃, ʻo ke kiʻekiʻe loa o ka fiber kalapona hiki ke hiki i ka 500 ℃. Ma ke ʻano kūikawā, hiki i ka fiber basalt i ka hana 600 ℃, hiki i kona ikaika ma hope o ka haki ʻana ke mālama i ka 80% o ka ikaika mua; hana ma 860 ℃ me ka ʻole o ka emi ʻana, ʻoiai inā hiki ke mālama ʻia ke kūpaʻa mahana o ka huluhulu mineral maikaʻi loa i kēia manawa ma hope o ka haki ʻana ma 50% -60% wale nō, ua luku loa ʻia ka huluhulu aniani. ʻO ka fiber kalapona ma kahi o 300 ℃ ma kahi o CO a me CO2 hana. Hiki i ka fiber basalt ma 70 ℃ ma lalo o ka hana a ka wai wela ke mālama i ka ikaika kiʻekiʻe, hiki i ka fiber basalt i 1200 h ke nalowale i kahi hapa o ka ikaika.
④ Paʻa kemika maikaʻi a me ke kūpaʻa i ka palaho
Loaʻa i ka fiber basalt hoʻomau ka K2O, MgO) a me TiO2 a me nā mea ʻē aʻe, a ʻo kēia mau mea e hoʻomaikaʻi i ke kūpaʻa kemika o ka fiber a me ka hana wai ʻole he mea maikaʻi loa ia, a he hana koʻikoʻi loa ia. ʻOi aku ka maikaʻi o ia mea ke hoʻohālikelike ʻia me ke kūpaʻa kemika o nā fibers aniani, ʻoi aku hoʻi i nā media alkaline a me acidic, ʻoi aku ka maopopo o nā fibers basalt i loko o ka saturated Ca (OH) 2 solution a me ka sima a me nā media alkaline ʻē aʻe e hiki ke mālama i kahi kū'ē kiʻekiʻe i ka hana alkali corrosion.

⑥ Hana pale leo maikaʻi loa
He maikaʻi loa ka pale leo o ka fiber basalt hoʻomau, ka hana omo leo, hiki ke aʻo ʻia ke koina omo leo leo like ʻole mai ka fiber i nā ʻano like ʻole, me ka hoʻonui ʻana i ke alapine (frequency), e hoʻonui nui ʻia kona koina omo leo. E like me ke koho ʻana o ke anawaena o ka fiber basalt 1-3μm i hana ʻia me (ka nui o 15 kg/m3, ka mānoanoa o 30mm) nā mea omo leo, i loko o ke kani no nā kūlana 100-300 Hz, 400-900 Hz a me 1200-7,000 HZ, ʻo ke koina omo mea fiber he 0.05 ~ 0.15, 0.22 ~ 0.75 a me 0.85 ~ 0.93, kēlā me kēia.
⑦ Nā waiwai dielectric koʻikoʻi
ʻOi aku ka nui o ke kū'ē'ē o ka nui o ke olonā basalt hoʻomau ma mua o kaʻO ke aniani E, nona nā waiwai dielectric maikaʻi loa. ʻOiai aia ka basalt ore i kahi hapa nui o ka aneane 0.2 o nā oxides conductive, akā ʻo ka hoʻohana ʻana i ka mea infiltrating kūikawā i ka mālama ʻana i ka ʻili kūikawā, ʻo ke kihi o ka dielectric fiber basalt tangent ma mua o ke aniani fiber he 50% haʻahaʻa, ʻoi aku ka kiʻekiʻe o ka resistivity volume o ka fiber ma mua o ke aniani fiber

⑧ Ka hoʻohālikelike ʻana o ka silicate kūlohelohe
Hoʻopuehu maikaʻi me ka sima a me ka sima, ka pilina ikaika, ke koina kūlike o ka hoʻonui ʻana a me ka ʻaelike wela, ke kūpaʻa maikaʻi o ka wā.
⑨ Hoʻemi i ka omo ʻana o ka makū
ʻOi aku ka liʻiliʻi o ka omo ʻana o ka makū o ka fiber basalt ma mua o 0.1%, haʻahaʻa ma mua o ka fiber aramid, ka huluhulu pōhaku a me ka asbestos.
⑩ Haʻahaʻa ka hoʻokele wela
ʻO ke alakaʻi wela o ka fiber basalt he 0.031 W/mK - 0.038 W/mK, ʻoi aku ka haʻahaʻa ma mua o ka fiber aramid, fiber alumino-silicate, fiber aniani alkali-free, rockwool, fiber silicon, fiber carbon a me ke kila kila.

ʻO ke aniani fiberglass
ʻO ka Fiberglass, kahi mea metala ʻole inorganic me ka hana maikaʻi loa, he nui nā pono like ʻole e like me ka insulation maikaʻi, ke kūpaʻa wela, ke kūpaʻa maikaʻi i ka corrosion, ka ikaika mechanical kiʻekiʻe, akā ʻo ka hemahema ka palupalu a me ke kūpaʻa abrasion maikaʻi ʻole. Hoʻokumu ʻia ia ma luna o ka chlorite, ke one quartz, ka limestone, ka dolomite, ka pōhaku boron calcium, ka pōhaku boron magnesium ʻeono ʻano ores e like me nā mea maka ma o ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe, ke kaha kiʻi ʻana, ka wili ʻana, ka ulana ʻana a me nā kaʻina hana ʻē aʻe i loko o ka hana ʻana o ke anawaena o kona monofilament no kekahi mau microns a ʻoi aku ma mua o 20 microns, e like me ka lauoho o 1/20-1/5, ʻo kēlā me kēia pūʻulu o nā filament fiber he mau haneli a i ʻole nā ​​​​kaukani o ka haku mele monofilament.ʻO ke aniani fiberglasshoʻohana pinepine ʻia ia he mau mea hoʻoikaika i nā mea i hui pū ʻia, nā mea hoʻomehana uila a me nā mea hoʻomehana wela, nā papa kaapuni a me nā wahi ʻē aʻe o ka hoʻokele waiwai o ka ʻāina.

Nā Waiwai Mea
Heheʻe kiko: ʻO ke aniani he ʻano non-crystalline, ʻaʻohe kiko heheʻe paʻa, ua manaʻo nui ʻia ʻo ka palupalu o ka kiko he 500 ~ 750 ℃.
Kikowaena paila: ma kahi o 1000 ℃
Ka nui o ke kinoea: 2.4~2.76 g/cm3
Ke hoʻohana ʻia ke aniani fiber ma ke ʻano he mea hoʻoikaika no nā plastics i hoʻoikaika ʻia, ʻo ka hiʻohiʻona nui loa kona ikaika tensile kiʻekiʻe. ʻO ka ikaika tensile i ke kūlana maʻamau he 6.3 ~ 6.9 g / d, mokuʻāina pulu 5.4 ~ 5.8 g / d. Maikaʻi ke kūpaʻa wela, ʻaʻohe hopena o ka mahana a hiki i ka 300 ℃ ma ka ikaika. Loaʻa iā ia ka insulation uila maikaʻi loa, he mea hoʻomehana uila kiʻekiʻe kiʻekiʻe, hoʻohana pū ʻia no nā mea insulation a me nā mea pale ahi. ʻO ka maʻamau, ua pala wale ʻia e ka alkali i hoʻopaʻa ʻia, ka waikawa hydrofluoric a me ka waikawa phosphoric i hoʻopaʻa ʻia.
