Mea Hana Hou Refractory

  • Calcium carbide

    Kālika kalika

    ʻO ka calcium carbide kahi hui inorganic, nā aniani keʻokeʻo, nā huahana ʻoihana he hinahina ʻeleʻele, a he poni a hina paha ka paukū kea. Hana kolohe ia i ka wā e hālāwai ai me ka wai, e hana ana i ka acetylene a hoʻokuʻu i ka wela. ʻO ka kalepika carbide kahi mea waiwai nui a me nā mea waiwai, hoʻohana nui ʻia e hana i ke kinoea acetylene. Hoʻohana pū ʻia i ka synthetic synthes, oxyacetylene welding, a pēlā aku. Kino a me nā kemika waiwai: He melemele-ʻeleʻele a paʻa ʻeleʻele blocky ka mea, a ʻo ka huahana maʻemaʻe he aniani keʻokeʻo (ʻo ka mea me CaC2 kiʻekiʻe he poni). He kiʻekiʻena ʻo 2.22 g / cm3 a me kahi kiko hoʻoheheʻe o 2300 ° C (e pili ana i ka ʻike o CaC2). Hana kolohe koke ia ke hui me ka wai e hana i ka acetylene a hoʻokuʻu i ka wela. Hoʻololi ke kiko hoʻoheheʻe me nā ʻike ʻokoʻa calcium.

  • Bauxite

    Bauxite

    ʻO ka ʻāpana nui o ka bauxite ka alumina, kahi i hydrated alumina i loaʻa nā impurities a he ʻano mineral o ka honua. Keʻokeʻo a keʻokeʻo keʻokeʻo, melemele melemele a i ʻole ʻulaʻula māmā ma muli o ka ʻike hao. Ka nui 3.45g / cm3, ʻoʻoleʻa 1 ~ 3, opaque a palupalu. Paʻakikī loa e hoʻoheheʻe. Hoʻokomo ʻole ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i ka waikawa sulfuric a me ka hopena sodium hydroxide. Hoʻohana nui ʻia no ka hoʻoheheʻe ʻana i ka aluminika a me ka hana ʻana i nā mea pale.
    He paʻakikī loa ka hoʻohui ʻana o ka bauxite, a he manawa maʻamau ia no nā ʻano like ʻole o ka hydrous alumina ore me nā kumuwaiwai ʻokoʻa loa. E like me boehmite, diaspore a me gibbsite (Al2O3 · 3H2O); ua haku ʻia kekahi o ka diaspore a me kaolinite (2SiO2 · Al2O3 · 2H2O); ua haku ʻia kekahi mau mea o kaolinite a hāhai i ka hoʻonui ʻana i ka ʻike o kaolinite ʻo ia hoʻi ka bauxite ākea a i ʻole kaolinite pālolo. Hoʻokumu ʻia ka Bauxite e nā anilā kemika a i ʻole nā ​​hopena exogenous. Aia kekahi mau minela maʻemaʻe, a loaʻa mau kekahi mau minela haumia, ʻoi aku ka nui o nā minelala pālolo, nā minelala hao, nā mineral titanium a me nā minela kaumaha detrital.

  • Chamotte

    ʻO Chamotte

    ʻO Chamotte kahi pālolo paʻakikī paʻakikī kiʻekiʻe i hana ʻia ma Zibo, Shandong Province, Kina. ʻO ka maʻa mau Al2O3 o ka chamotte ore he 38%, ma hope o ka kalena ʻana ka ʻike Al2O3 ma kahi o 44%, a me Fe2O3 <2%. Kūpaʻa ke ʻano, kūlike ke ʻano, paʻa ka hanana, a keʻokeʻo ka ʻāpana a keʻokeʻo. Hoʻohana ʻia ia e hana i nā mea hana refractory pālolo kiʻekiʻe. ʻO ka huaʻōlelo ka clinker pālolo paakiki papa mua, ʻo nā mea hana kemika nui ʻo AL2O3 a me SiO2, me ka Fe2O3 liʻiliʻi a me nā helu huli o Na2O a me K2O. ʻO ka mineral nui kaolin.

    ʻO ka chamotte a mākou e kāhea aku nei e kuhikuhi iā CALCINED CLAY. . ʻO ka ʻike o Al2O3 i ka chamotte i helu ʻia ma kahi o 44%, a ʻo ka ʻike o Fe2O3 ʻaʻole i ʻoi aku ma mua o 2%. Kūpaʻa ke ʻano, kūlike ke ʻano, paʻa ka hanana, a ʻāpana nā ʻāpana iwi.

    ʻO nā waihoʻoluʻu maʻamau o chamotte ma hope o ke kalina wela kiʻekiʻe: keʻokeʻo keʻokeʻo, hina hina, ʻeleʻele melemele māmā, a me kahi liʻiliʻi o ka pale hao ʻalani.

  • Andalusite

    Andalusite

    ʻO Andalusite kahi mineral aluminosilicate, ʻo ia ka mea maka no ka hana ʻana i nā mea refractory a me ka porcelain i nā hunaahi. He mineral maʻamau ia o ka metamorphism thermal papa haʻahaʻa, a ʻike pinepine ʻia i nā pōhaku lepo i ka hoʻopili ʻana me nā ʻāpana metamorphic. Hoʻokumu ʻia ia ma lalo o nā kūlana o ka gradient geothermal kiʻekiʻe a me ke kaomi haʻahaʻa i ka lakio o ka mahana.

    ʻO Andalusite he kolamu aniani kolamu, a ʻo kona ʻāpana kea ke aneane ʻahā. ʻĀkoakoa nā aniani Andalusite i loko o nā radial a i ʻole ʻano granular. Kāhea pinepine ka poʻe i ka radial andalusites "pōhaku chrysanthemum", ʻo ia hoʻi ua like lākou me nā petal o ka chrysanthemum.
