ʻAla Basalt
ʻO ka fiber basalt kahi fiber mau i huki ʻia mai ka basalt maoli. He pōhaku basalt ia ma 1450 ℃ ~ 1500 ℃ ma hope o ka hoʻoheheʻe ʻana, ma o ka platinum-rhodium alloy wire e kaha ana i ka leakage plate huki wikiwiki i hana ʻia me ka fiber mau. He ʻeleʻele ka waihoʻoluʻu o ka fiber basalt maoli. ʻO ka basalt fiber kahi ʻano hou o ka ʻōmaʻomaʻo kūlohelohe kūlohelohe ʻōmaʻomaʻo kiʻekiʻe, kahi i haku ʻia me ka silica, alumina, calcium oxide, magnesium oxide, iron oxide a me titanium dioxide a me nā mea ʻē aʻe.Basalt fiber mauʻaʻole wale ka ikaika kiʻekiʻe, akā he mau ʻano mea maikaʻi loa e like me ka insulation uila, ka pale ʻana i ka corrosion, ke kiʻekiʻe o ka wela a me nā mea ʻē aʻe. Eia kekahi, ua hoʻoholo ke kaʻina hana o ka fiber basalt e hana i ka liʻiliʻi o ka ʻōpala, ka pollution liʻiliʻi i ke kaiapuni, a hiki ke hoʻohaʻahaʻa pono ʻia ka huahana i ke kaiapuni ma hope o ka ʻōpala, me ka ʻole o ka pōʻino, no laila he ʻōmaʻomaʻo maoli ia, nā mea kūlohelohe. Ua hoʻohana nui ʻia ka basalt mau fibers i loko o ka fiber-reinforced composites, friction materials, shipbuilding materials, heat-insulating materials, the automotive industry, high-reinforced filtration fabrics, and protect fields.
Nā hiʻohiʻona
① Loaʻa nā lako maka
Basalt fiberUa hana ia i ka basalt oka hehee a huki, a me ka basalt oka ma ka Honua a me ka mahina mea pono hoʻopaʻa 'ia, mai ka maka kumu kumu kūʻai i mea haʻahaʻa.
② Mea pili i ke kaiapuni
ʻO ka basalt ore kahi mea kūlohelohe, ʻaʻohe boron a i ʻole nā ​​mea hoʻoheheʻe alkali ʻē aʻe i hoʻokuʻu ʻia i ka wā o ke kaʻina hana, no laila ʻaʻohe mea ʻino i hoʻoheheʻe ʻia i ka uahi, ʻaʻole e hoʻohaumia ka lewa. Eia kekahi, he lōʻihi ke ola o ka huahana, no laila, he ʻano hou o ka ʻōmaʻomaʻo ʻeleʻele e mālama i nā mea me ka haʻahaʻa haʻahaʻa, hana kiʻekiʻe a me ka hoʻomaʻemaʻe kūpono.
③ Kūleʻa ka wela a me ka wai
ʻO ka lōʻihi o ka wela o ka hana basalt fiber maʻamau he 269 ~ 700 ℃ (kahi palupalu o 960 ℃), aʻo ka fiber aniani no kahi 60 ~ 450 ℃, ʻo ke kiʻekiʻe kiʻekiʻe o ka carbon fiber hiki ke hiki wale i 500 ℃. ʻO keʻano, ka fiber basalt i 600 ℃ hana, kona ikaika ma hope o ka hoʻomaha hiki ke mālama i ka 80% o ka ikaika mua; hana ma 860 ℃ me ka shrinkage, ʻoiai inā hiki ke mālama ʻia ke kūpaʻa mahana o ka hulu hipa mineral maikaʻi loa i kēia manawa ma hope o ka hoʻomaha ʻana ma 50% -60%, pau loa ka huluhulu aniani. ʻO ka fiber carbon ma kahi o 300 ℃ ma ka hana CO a me CO2. ʻO ka fiber basalt ma 70 ℃ ma lalo o ka hana o ka wai wela hiki ke mālama i ka ikaika kiʻekiʻe, ʻo ka basalt fiber i 1200 h hiki ke nalowale i kahi hapa o ka ikaika.
④ Paʻa kemika maikaʻi a me ka pale ʻana i ka corrosion
Loaʻa i ka fiber basalt mau K2O, MgO) a me TiO2 a me nā ʻāpana ʻē aʻe, a ʻo kēia mau ʻāpana e hoʻomaikaʻi i ke kūpaʻa ʻana o ke kino o ka fiber a me ka hana wai ʻole he mea maikaʻi loa, pāʻani i kahi kuleana koʻikoʻi. ʻOi aku ka maikaʻi i ka hoʻohālikelike ʻia me ke kūpaʻa kemika o nā kīʻaha aniani, ʻoi aku ka nui o ka alkaline a me ka acidic media i ʻoi aku ka maopopo o ka basalt fibers i ka saturated Ca (OH) 2 solution a me ka cement a me nā media alkaline ʻē aʻe hiki ke hoʻomau i ke kūpaʻa kiʻekiʻe i ka hana corrosion alkali.

⑤ Modulus kiʻekiʻe o ka elasticity a me ka ikaika tensile
ʻO ka modulus o ka elasticity o ka fiber basalt he 9100 kg / mm-11000 kg / mm, ʻoi aku ka kiʻekiʻe ma mua o ka fiber glass alkali-free, asbestos, aramid fiber, polypropylene fiber a me silica fiber. ʻO ka ikaika tensile o ka fiber basalt he 3800-4800 MPa, ʻoi aku ka kiʻekiʻe ma mua o ka nui o ke kalapona kalapona nui, ka fiber aramid, ka pulu PBI, ke kila kila, ka boron, ka alumina fiber, a ua hoʻohālikelike ʻia me ke aniani S. ʻO ka fiber basalt he 2.65-3.00 g / cm3 a me ka paʻakikī kiʻekiʻe o 5-9 degere ma ka paʻakikī paʻakikī Mohs, no laila, loaʻa iā ia ke kūpaʻa abrasion maikaʻi a me nā waiwai hoʻoikaika tensile. ʻOi aku ka ikaika o kona ikaika ma mua o nā fiber maoli a me nā fibers synthetic, no laila he mea hoʻoikaika maikaʻi loa ia, a ʻo kona mau ʻano mechanical maikaʻi loa aia ma ke alo o nā fibers hana kiʻekiʻe ʻehā.
⑥ ʻO ka hana hoʻoheheʻe kani maikaʻi
Hoʻomau basalt puluniu i maikaʻi leo insulation, kani absorption hana, mai ka puluniu ma okoa leo leo absorption coefficient hiki ke aʻo, me ka hoʻonui pinepine, kona kani absorption coefficient mahuahua nui. E like me ke koho ana o ke anawaena 1-3μm basalt puluniu i hanaia o (density o 15 kg/m3, mānoanoa o 30mm) kani-absorbing mea, i ka leo no ka 100-300 Hz, 400-900 Hz a me 1200-7,000 HZ kūlana, ka puluniu mea absorption coefficient ~ 0.055 coefficient. 0.22~0.75 a me 0.85~0.93.
⑦ Nā waiwai dielectric koʻikoʻi
ʻO ka nui o ka resistivity o ka fiber basalt hoʻokahi ka nui o ka nui ma mua o kēlāE puluniu aniani, nona nā waiwai dielectric maikaʻi loa. ʻOiai ʻo ka basalt ore ka hapa nui o ka aneane 0.2 o ka conductive oxides, akā ʻo ka hoʻohana ʻana i ka infiltrating agent kūikawā kūikawā ma luna, ʻo ka basalt fiber dielectric consumer angle tangent ma mua o ke aniani fiber he 50% haʻahaʻa, ʻoi aku ka nui o ka resistivity o ka fiber ma mua o ke aniani fiber.

⑧ ʻO ka pilina silicate kūlohelohe
ʻO ka hoʻopuehu maikaʻi me ka sima a me ke kaʻa, ka hoʻopaʻa paʻa ʻana, ka coefficient kūlike o ka hoʻonui ʻana i ka wela a me ka hoʻopaʻa ʻana, maikaʻi ke kū ʻana i ka wā.
⑨ Hoʻemi haʻahaʻa i ka makū
