Nā Pōmaikaʻi 10 Kiʻekiʻe o ka Fiber Basalt

ʻO ke olonā basaltNā Pōmaikaʻi 10 Kiʻekiʻe

ʻO ka olonā basalthe fiber filament hoʻomau i hana ʻia mai nā mea kūlohelohe Pōhaku BasaltHoʻoheheʻe ʻia ka pōhaku ma 1450°C-1500°C a laila huki ʻia ma o kahi platinum-rhodium alloy bushing me ka wikiwiki kiʻekiʻe. ʻO ka fiber basalt maʻemaʻe he ʻeleʻele maʻamau. He ʻano hou ia o ka fiber inorganic, eco-friendly, hana kiʻekiʻe i haku ʻia me nā oxides e like me silicon dioxide, alumini oxide, calcium oxide, magnesium oxide, iron oxide, a me titanium dioxide. ʻAʻole wale ka ikaika kiʻekiʻe o ka fiber hoʻomau basalt akā he mau waiwai maikaʻi loa hoʻi e like me ka insulation uila, ke kūpaʻa ʻana i ka corrosion, a me ke kūpaʻa wela kiʻekiʻe. Eia kekahi, ʻo kāna hana hana e hoʻopuka i ka liʻiliʻi o ka ʻōpala a me ka haumia o ke kaiapuni, a hiki i ka huahana i hoʻolei ʻia ke hoʻohaumia maoli me ka ʻole o ka pōʻino, e lilo ia i mea ʻōmaʻomaʻo maoli a me ka eco-friendly. Ua helu ʻo Kina i ka fiber basalt ma ke ʻano he hoʻokahi o nā fibers koʻikoʻi ʻehā no ka hoʻomohala ʻana (me ke fiber carbon, aramid, a me ka polyethylene kaumaha molekala kiʻekiʻe loa) a ua hoʻokō i ka hana ʻoihana. Hoʻohana nui ʻia ka fiber basalt hoʻomau i nā composites i hoʻoikaika ʻia i ka fiber, nā mea friction, ke kūkulu moku, ka ʻoihana kaʻa, a me nā noi wela kiʻekiʻe a me ka pale.

1. Nā Mea Maka Nui

   Hana ʻia ke olonā basalt mai ka pōhaku basalt, kahi i loaʻa i nā nui he nui ma ka Honua a me ka mahina. Mālama kēia i ke kumukūʻai o nā mea maka i haʻahaʻa.

2. Mea Pilikino Kaiapuni

   ʻO ka basalt He mea kūlohelohe ka pōhaku. ʻAʻole hoʻokuʻu kāna hana hana i ka boron a i ʻole nā ​​​​oxides metala alkali ʻē aʻe, no laila ʻaʻole i loaʻa i ka lepo a me ka uahi nā mea ʻino a ʻaʻole hoʻi e haumia i ka lewa. He lōʻihi ke ola o ka huahana, e lilo ia i mea haʻahaʻa ke kumukūʻai, hana kiʻekiʻe, a maʻemaʻe hoʻi.

3. Ke Kū'ē Mahana Kiʻekiʻe a me ka Wai

   Hoʻomau olonā basalt hiki ke hana ma kahi ākea o ka mahana mai -269°C a i 700°C (me kahi kiko palupalu o 960°C). ʻOi aku kēia ma mua o gke kaulahao wahine (-60°C a i 450°C) a me ke olonā kalapona (max 500°C). ʻO ka mea nui, mālama ka olonā basalt i 80% o kona ikaika mua ma hope o ka hana ʻana ma 600°C a ʻaʻole e emi iho ma 860°C. Mālama pū ia i ka ikaika kiʻekiʻe ma hope o ka hōʻike ʻia ʻana i ka wai wela 70°C.

4. Kūlana Kemika Maikaʻi Loa a me ke Kū'ē ʻana i ka ʻAʻai

   Aia i loko o ka fiber basalt nā ʻāpana e like me K₂O, MgO, a me TiO₂, kahi e hoʻomaikaʻi nui ai i kona kūpaʻa ʻana i ka pala kemika a me ka wai. ʻOi aku kona kūpaʻa kemika ma mua o ka fiber aniani, ʻoi aku hoʻi i nā wahi alkaline a me nā wahi acidic. Hōʻike ka fiber basalt i ke kūpaʻa maikaʻi loa i ka pala alkali i nā hopena Ca(OH)₂ saturated a me ka sima.

5. ʻO ke Modulus Elastic kiʻekiʻe a me ka ikaika Tensile

   ʻOi aku ke kiʻekiʻe o ka modulus elastic o ka fiber basalt (9100-11000 kg/mm) ma mua o ka fiber E-glass, asbestos, aramid, polypropylene, a me nā fiber silicon. ʻOi aku ka ikaika o kona tensile (3800-4800 MPa) ma mua o ka fiber kalapona nui-tow, aramid, fiber PBI, fiber kila, fiber boron, a me ka fiber alumina, a ua like ia me ka fiber S-glass. Me ka density o 2.65-3.00 g/cm³ a ​​me ka paʻakikī Mohs o 5-9, hāʻawi ia i ke kūpaʻa ʻana i ka ʻaʻahu maikaʻi loa a me ka hoʻoikaika tensile. ʻOi aku ka ikaika o kona mechanical ma mua o nā fibers kūlohelohe a me synthetic, e lilo ia i mea hoʻoikaika kūpono.

6. Hana Hoʻokaʻawale Leo Koʻikoʻi

   Loaʻa i ke olonā basalt hoʻomau nā waiwai maikaʻi loa o ke kani a me ka walaʻau. Hoʻonui nui ʻia kona coefficient omo kani me ka alapine (frequency). No ka laʻana, ʻo kahi mea omo kani i hana ʻia me nā olonā basalt 1-3 μm ke anawaena (me ka nui o 15 kg/m³ a me ka mānoanoa o 30 mm) he mau coefficient omo kani o 0.05-0.15 ma 100-300 Hz, 0.22-0.75 ma 400-900 Hz, a me 0.85-0.93 ma 1200-7000 Hz.

7. Nā Waiwai Dielectric Koʻikoʻi

   ʻO ke olonā basalt mauʻOi aku ka nui o ke kū'ē'ē o ka leo ma mua o ke olonā aniani E, e hāʻawi ana iā ia i nā waiwai dielectric maikaʻi loa. ʻOiai aia ka pōhaku basalt ma kahi o 0.2% o nā oxides conductive, hiki i nā hana ʻili kūikawā me nā mea hoʻonui ke hōʻemi i ka dielectric loss tangent ma 50% i hoʻohālikelike ʻia me ke olonā aniani, a ʻoi aku ke kiʻekiʻe o kona kū'ē'ē leo.

8. Hoʻohālikelike Silicate kūlohelohe

   Hoʻopuehu maikaʻi ia a pili pono me ka sima a me ka sima. He kūlike kona mau coefficients hoʻonui wela a me ka ʻūmiʻi, a he kūpaʻa maikaʻi kona i ka wā.

9. Ka Hoʻomoʻa Haʻahaʻa o ka Makū

   ʻOi aku ka haʻahaʻa o ka omo ʻana o ka wai ma mua o ka fiber aramid, ka huluhulu pōhaku, a me ka asbestos ma lalo o 0.1% o ka fiber basalt.

10. Ka Hoʻokele Haʻahaʻa Haʻahaʻa

    ʻO ke alakaʻi wela o ka olonā basalt he 0.031-0.038 W/m·K, ʻoi aku ka haʻahaʻa ma mua o ke olonā aramid, ke olonā silicate alumini, ke olonā aniani-E, ka huluhulu pōhaku, ke olonā silicon, ke olonā kalapona, a me ke kila kila.
