ʻO 10 mau mea maikaʻi o ka basalt fiber

ʻAla Basalt: He 10 Pookela

Basalt fiberhe fiber filament mau i hanaia mai ke ano maoli Pōhaku Basalt. Hoʻoheheʻe ʻia ka pōhaku ma 1450 ° C-1500 ° C a laila huki ʻia ma o ka platinum-rhodium alloy bushing i ka wikiwiki kiʻekiʻe. He ʻeleʻele maʻamau ka fiber basalt maʻemaʻe. He ʻano hou ia o ka fiber inorganic, eco-friendly, high-performance fiber i haku ʻia me nā oxides like silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, a me titanium dioxide. ʻAʻole wale ka ikaika kiʻekiʻe o ka basalt continuous fiber akā hoʻonani pū kekahi i nā waiwai maikaʻi loa e like me ka insulation uila, ke kūpaʻa corrosion, a me ke kūpaʻa wela kiʻekiʻe. Eia kekahi, ʻo kāna kaʻina hana e hoʻohua i ka ʻōpala liʻiliʻi a me ka haumia o ke kaiapuni, a ʻo ka huahana i hoʻolei ʻia e hiki ke hoʻohaʻahaʻa maoli me ka ʻole o ka pōʻino, e lilo ia i mea ʻōmaʻomaʻo maoli a me ka ʻoluʻolu. Ua helu ʻo Kina i ka fiber basalt ma ke ʻano he ʻehā kī nui no ka hoʻomohala ʻana (me ka fiber carbon, aramid, a me ultra-high molecular weight polyethylene) a ua hoʻokō i ka hana ʻoihana. Hoʻohana nui ʻia ka fiber basalt i kēia manawa i nā composite i hoʻoikaika ʻia i ka fiber, nā mea friction, ka hana moku, ka ʻoihana kaʻa, a me nā noi kiʻekiʻe a me ka pale.

1. Lahui Maka

   Hana ʻia ka fiber basalt mai ka pōhaku basalt, i loaʻa i nā mea nui ma ka Honua a me ka mahina. Mālama kēia i nā kumu kūʻai maka.

2. Mea Pilikino

   Basalt ʻO ka pōhaku he mea maoli. ʻAʻole hoʻokuʻu i kāna kaʻina hana i ka boron a i ʻole nā ​​​​mea hoʻoheheʻe metala alkali ʻē aʻe, no laila ʻaʻole i loko o ka lepo a me ka uahi nā mea ʻino a ʻaʻole hoʻohaumia i ka lewa. He lōʻihi hoʻi ke ola o ka huahana, e lilo ia i kumu kūʻai haʻahaʻa, hana kiʻekiʻe, a maʻemaʻe hoʻi i nā mea ʻōmaʻomaʻo hou.

3. Kūleʻa kiʻekiʻe a me ka wai

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

4. Paʻa Kemika maikaʻi loa a me ka pale ʻana i ka corrosion

   Loaʻa i ka fiber basalt nā ʻāpana e like me K₂O, MgO, a me TiO₂, kahi e hoʻomaikaʻi maikaʻi ai i kona kūpaʻa ʻana i ka ʻino a me ka wai. ʻOi aku ka paʻa o ke kemika ma mua o ka fiber aniani, ʻoi aku hoʻi ma nā wahi alkaline a me ka waikawa. ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka basalt fiber i ka ʻino alkali ma nā hoʻonā Ca(OH)₂ saturated a me ka sima.

5. ʻO ke kiʻekiʻe elastic modulus a me ka ikaika tensile

   ʻOi aku ke kiʻekiʻe o ka modulus elastic o Basalt fiber (9100-11000 kg/mm) ma mua o ka fiber E-glass fiber, asbestos, aramid, polypropylene, a me nā fibers silicon. ʻOi aku kona ikaika tensile (3800-4800 MPa) ma mua o ka nui-tow carbon fiber, aramid, PBI fiber, fiber steel, boron fiber, a me alumina fiber, a ua hoʻohālikelike ʻia me ka fiber S-glass. Me ka mānoanoa o 2.65-3.00 g/cm³ a ​​me ka paʻakikī Mohs o 5-9, hāʻawi ia i ka pale lole maikaʻi loa a me ka hoʻoikaika tensile. ʻOi aku kona ikaika mechanical ma mua o nā fila kūlohelohe a me ka synthetic, e lilo ia i mea hoʻoikaika kūpono.

6. Kūlana Leo Kūleʻa

   Loaʻa i ka fiber basalt mau ke kani maikaʻi a me ka leo absorption. Hoʻonui nui ʻia ka helu hoʻoheheʻe kani me ka pinepine. No ka laʻana, he mea kani-absorption i hana ʻia me 1-3 μm anawaena basalt fibers (me ka mānoanoa o 15 kg/m³ a me ka mānoanoa o 30 mm) loaʻa nā coefficients absorption leo o 0.05-0.15 ma 100-300 Hz, 0.22-0.75 ma 400,-90. 1200-7000 Hz.

7. Na Mea Dielectric Kaulana

   ʻO ka fiber basalt mau'O ka leo resistivity he kauoha o ka magnitude oi aku mamua o E-aniani fiber, haawi ia i maikai dielectric waiwai. ʻOiai ʻo ka pōhaku basalt he kokoke i 0.2% conductive oxides, hiki i nā lāʻau lapaʻau kūikawā me nā mea nui ke hoʻemi i ka tangent poho dielectric e 50% ke hoʻohālikelike ʻia me ka fiber aniani, a ʻoi aku ka nui o kona resistivity.

8. Kūlike Silicate Kūlohelohe

   Hoʻopuehu maikaʻi a hoʻopaʻa paʻa me ka sima a me ke kaʻa. ʻO kona hoʻonui ʻana i ka wela a me nā coefficient hoʻopaʻa paʻa paʻa, a maikaʻi kona kūʻē ʻana i ka wā.

9. Haʻahaʻa haʻahaʻa haʻahaʻa

   Loaʻa i ka basalt fiber kahi māmā absorption ma lalo o 0.1%, ʻoi aku ka haʻahaʻa ma mua o ka fiber aramid, ka hulu pōhaku, a me ka asbestos.

10. Haʻahaʻa Thermal Conductivity

    ʻO ka thermal conductivity o Basalt fiber he 0.031-0.038 W/m·K, ʻoi aku ka haʻahaʻa ma mua o ka fiber aramid, alumini silicate fiber, E-aniani fiber, pōhaku huluhulu, silicon fiber, carbon fiber, a me ke kila kila.
