ʻO ka ʻōmaʻomaʻo ʻōmaʻomaʻo hou o ka fiber hana kiʻekiʻe ʻo Basalt Fiber

He aha ka Basalt Fiber?
ʻO ka fiber basalt kahi fiber mau i hana ʻia me ka pōhaku basalt maoli ma ke ʻano he kumu kumu.Ma hope o ka hoʻoheheʻe ʻana ma 1450-1500 ℃, huki ʻia ia ma o ka platinum-rhodium alloy kiʻi bushing i ka wikiwiki kiʻekiʻe.He ʻeleʻele maʻamau ka waihoʻoluʻu a he ʻulaʻula metala kona.Hoʻokumu ʻia ia me nā oxides e like me ke silicon dioxide, aluminika ʻokikene, calcium oxide, magnesium oxide, iron oxide a me titanium dioxide.He nui nā waiwai maikaʻi o ka basalt fiber e like me ka ikaika kiʻekiʻe, ka insulation uila, ka pale ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, ka anti-aging, a me nā mea ʻē aʻe, a he kūpono maikaʻi me ke kaiapuni a ʻaʻole ia e hana i ka pollution lua.No laila, he ʻōmaʻomaʻo ʻōmaʻomaʻo kiʻekiʻe-hana hou ka mea palekana kaiapuni.
Ua helu koʻu ʻāina i ka fiber basalt ma ke ʻano he ʻehā o nā fibers nui (carbon fiber, aramid fiber, ultra-high molecular weight polyethylene, basalt fiber) no ka hoʻomohala kī.Loaʻa i nā pono o ka mokulele a me nā ʻāina ʻē aʻe nā manaʻo noiʻi ākea.
ʻO ke kaʻina hana o ka fiber basalt
Hoʻohana ʻia ka pōhaku basalt maoli i hana ʻia e ka lua pele e like me nā mea maka, ʻoki ʻia a hoʻokomo ʻia i loko o ka umu hoʻoheheʻe, wela i kahi kūlana hoʻoheheʻe ʻia o 1450 ~ 1500 ° C, a huki koke ʻia ma o ka platinum-rhodium alloy wire drawing bushing, a me basalt fiber. hana ʻia ma kēia ʻano.
ʻO ka pōkole, ʻo ke kaʻina hana o ka fiber basalt e "kaui" i ka pōhaku basalt pele paʻakikī i loko o ke kilika i ka wela kiʻekiʻe.
ʻO ke anawaena o ka fiber basalt i hana ʻia e ka ʻenehana i kēia manawa hiki ke hiki i 6 ~ 13μm, ʻoi aku ka lahilahi ma mua o ka lauoho.
Hōʻike ʻia kāna kaʻina hana ma ke kiʻi ma lalo nei.

Magma hehee

Kiʻi kiʻi
Ma ke ʻano he amorphous inorganic silicate waiwai, basalt fiber he manawa hana pōkole, kaʻina hana maʻalahi, ʻaʻohe wai ʻona a me nā kinoea ʻōpala, a me ka waiwai hoʻohui kiʻekiʻe.Ua ʻike ʻia ʻo ia ka "mea hou ʻōmaʻomaʻo" i ke kenekulia 21.

ʻO ka hana maikaʻi o ka fiber basalt
He gula ka waihoʻoluʻu ʻana o nā fiber basalt maʻemaʻe maʻemaʻe a ʻike ʻia e like me nā cylinders maʻemaʻe me kahi ʻāpana keʻa pōʻai maikaʻi.ʻO ka fiber basalt he kiʻekiʻe kiʻekiʻe a kiʻekiʻe ka paʻakikī, no laila he kūpaʻa maikaʻi loa ia a me ka ikaika tensile.ʻO ka fiber basalt kahi mea amorphous, a ʻo ka mahana o kāna lawelawe ma ke ʻano -269 ~ 700 ° C (ʻo 960 ° C ka mea palupalu).He ʻakika a me ka alkali, he ikaika ka pale UV, haʻahaʻa hygroscopicity, a me ke kūpaʻa kūlohelohe maikaʻi.Eia kekahi, loaʻa iā ia nā mea maikaʻi o ka insulation maikaʻi, ke kānana wela kiʻekiʻe, ka pale ʻana i ka radiation a me ka neʻe ʻana o ka hawewe maikaʻi, ke kūpaʻa haʻalulu thermal, ka hoʻomaʻemaʻe kaiapuni a me ka lakene maikaʻi loa o ka hana ʻana i ke ʻano o ke ʻano.

Pono nā mea maka
Hana ʻia ka fiber basalt ma ke kaha kiʻi ʻana ma hope o ka hoʻoheheʻe ʻana i ka ʻaila basalt, a ʻo ka mālama ʻana o ka ʻaila basalt ma ka honua a me ka mahina he mea kūpono loa, a ʻoi aku ka haʻahaʻa o ke kumu kūʻai.
Nā Mea Hana Pilikino
ʻO ka basalt ore kahi mea kūlohelohe, ʻaʻohe boron a i ʻole nā ​​​​mea ʻokiʻoki alkali ʻē aʻe i hoʻokuʻu ʻia i ka wā o ke kaʻina hana, no laila ʻaʻohe mea ʻino e hoʻoheheʻe ʻia i ka uahi a me ka lepo, ʻaʻole ia e hoʻohaumia i ka lewa.Eia kekahi, he lōʻihi ke ola lawelawe o ka huahana, no laila, he ʻano hou o ka ʻōmaʻomaʻo ʻeleʻele ʻeleʻele mea palekana me ka haʻahaʻa haʻahaʻa, hana kiʻekiʻe a me ka hoʻomaʻemaʻe kūpono.
ʻO ka wela kiʻekiʻe a me ka pale wai
ʻO ka pae mahana hana o ka fiber basalt mau loa he -269 ~ 700 ° C (ʻo 960 ° C ka palupalu), ʻoiai ʻo ka fiber aniani -60 ~ 450 ° C, a ʻo ka mahana hana kiʻekiʻe o ke kalapona kalapona hiki ke hiki i 500 wale nō. °C.ʻOi loa i ka wā e hana ai ka fiber basalt ma 600 ° C, hiki i kona ikaika ma hope o ka haʻihaʻi ke mālama i ka 80% o kona ikaika mua;ke hana ia ma 860 ° C me ka hoʻohaʻahaʻa ʻole, ʻo ka huluhulu mineral me ke kūpaʻa mahana maikaʻi loa hiki ke mālama wale i kēia manawa i ka ikaika ma hope o ka haki.50% -60%, pau loa ka huluhulu aniani.Hoʻopuka ka carbon fiber i ka CO a me CO2 ma kahi o 300°C.Hiki i nā pulu basalt ke mālama i ka ikaika kiʻekiʻe ma lalo o ka hana o ka wai wela ma 70 ° C, a hiki i nā pulu basalt ke lilo i hapa o ko lākou ikaika ma hope o 1200 h.
Paʻa kemika maikaʻi a me ka pale ʻana i ka corrosion
Loaʻa i ka fiber basalt mau nā ʻāpana e like me K2O, MgO) a me TiO2, a he mea maikaʻi loa kēia mau ʻāpana i ka hoʻomaikaʻi ʻana i ke kūpaʻa kino kino a me ka hana wai ʻole o ka fiber, a he hana koʻikoʻi.Ke hoʻohālikelike ʻia me ke kūpaʻa kemika o ka fiber aniani, ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi ma ka media alkaline a me ka waikawa.Hiki i ka fiber basalt ke hoʻomau i ke kūpaʻa kiʻekiʻe i ka hopena Ca (OH) 2 saturated a me ka media alkaline e like me ka sima.Nā waiwai ʻino alkali.
Modulus kiʻekiʻe o ka elasticity a me ka ikaika tensile
ʻO ka modulus elastic 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 silicon 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, aramid, PBI fiber, fiber kila, boron fiber, a me alumina fiber, a ua hoʻohālikelike ʻia me ka fiber glass S.ʻO ka fiber basalt he 2.65-3.00 g / cm3 a me ka paʻakikī kiʻekiʻe o 5-9 ma ka pālākiō Mohs, no laila ke kūpaʻa maikaʻi a me ka ikaika 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 kāna mau waiwai mechanical maikaʻi loa aia ma ka mua o nā fibers hana kiʻekiʻe.
ʻOi aku ka maikaʻi o ke kani ʻana
Loaʻa i ka fiber basalt hoʻomau ka hoʻohaʻahaʻa leo maikaʻi loa a me nā waiwai absorption kani.Hiki ke ʻike ʻia mai ka helu hoʻoheheʻe kani ʻana o ka fiber ma nā alapine like ʻole e piʻi nui ana ka nui o ke kani ʻana i ka piʻi ʻana o ke alapine.No ka laʻana, inā koho ʻia ka mea kani-absorbing i hana ʻia me ka basalt fiber me ke anawaena o 1-3μm (density 15 kg/m3, mānoanoa 30mm), ʻaʻole e pōʻino ka fiber ma lalo o ke ʻano o ka leo leo o 100-300 Hz. , 400-900 Hz a me 1200-7 000 HZ.ʻO nā helu hoʻoheheʻe kani o nā mea he 0. 05 ~ 0.15, 0. 22 ~ 0.75 a me 0.85~0.93.
ʻAno Dielectric Kūlana
ʻO ka nui resistivity o ka mau basalt fiber he kauoha o ka nui ma mua o ka E aniani puluniu, a he maikai dielectric waiwai.ʻOiai ʻo ka basalt ore i loaʻa i kahi conductive oxide me kahi hapa nui o kahi kokoke i 0.2, ma hope o ka mālama ʻana i ka ʻili kūikawā me kahi mea hoʻomaʻemaʻe kūikawā, ʻo ka tangent dielectric nalowale o ka fiber basalt he 50% haʻahaʻa ma mua o ka fiber aniani, a me ka resistivity leo o ka fiber. ʻoi aku ka kiʻekiʻe ma mua o ka fiber aniani.
Kūlike Silicate Kūlohelohe
Loaʻa iā ia ka hoʻopuehu maikaʻi me ka sima a me ke kaʻa, ka ikaika hoʻopaʻa paʻa, ka hoʻonui ʻana i ka wela a me ka coefficient contraction, a me ke kūpaʻa maikaʻi.
Haʻahaʻa hygroscopicity
ʻO ka hygroscopicity o ka fiber basalt ma lalo o 0.1%, ʻoi aku ka haʻahaʻa ma mua o ka aramid fiber, rock wool a me asbestos.
Haʻahaʻa thermal conductivity
ʻO ka thermal conductivity o ka basalt fiber he 0.031 W / m · K -0.038 W / m · K, ʻoi aku ka haʻahaʻa ma mua o ka fiber aramid, alumini silicate fiber, alkali-free aniani fiber, rock wool, silicon fiber, carbon fiber a me kuhili. kila.
Hoʻohālikelike ʻia me nā fibers ʻē aʻe, ʻoi aku ka maikaʻi o ka fiber basalt ma nā ʻano he nui.
