Calcined Alumina
Calcined Alumina mea he kalepa Alumina a Aluminum'okesaside. He keʻokeʻo ka pauka. Kekahi o nā 'ano poʻokela o Calcined Alumina o kona paakiki i ka 9 ma mohs pālākiō. Aia i ka papa hanalima kahua o nā palapala noi no kēia 'ano o ka alumina a me ka helu o ke kiʻiona papa e hua mai la e halawai me na mea e pono ai.
'Ike o nā papa
1) Calcined Aluminum S-100 papa: White granular noa waikahe he lepo lā hele ma 150 m.
2) Calcined Aluminum S-300 papa: White superfine pauka hele nae 45 micron.
3) Calcined Alumina SCM papa: He hope hoʻowali papa he loa o ka superfine hele ma 45 micron.
4) Calcined Alumina S-300 PT: Ua Ua finely hoʻowali papa iloko olaila loa o ka superfine me ka ili honua lapaau ana.
Hoʻohana
hoʻohana me he kīhei pili mea i loko o ka wela iapaau ana o kūikawā oka a steels, He hana like me ka fluxing meakino i loko o ke anaina kanaka o ka kūikawā steels like me ka ke keʻena o ka haʻahaʻa anoe? Aiey aniani. Ua Ua hana like me ka constituent o kūikawā waiho pa dazes & ia mea hoʻohana like me ka maka mea no ka hana o ke kahua niho porcelains. He hana no refractory noi e like me pou insulators. He hana like me ka abrasive hoʻopale. He hana glazing pālolo nā kile.
Tabular Alumina (Kanaka) o keʻano o ka α-Al2O3 mea a ua hoʻomaka koke sintered e kiʻekiʻe wela kumuʻula laila, e kokololio ka huʻihuʻiʻana. Ka mea, i na ano o ka haʻahaʻa hamama porosity, a nui nā pōaka me ka paʻa spherical ili a i trapped maluna o hou-crystallization ma kokololio sintering. Tabular alumina mea o kiʻekiʻe refractoriness, maikaʻi thermal kŰia hoʻopale, fantastic Anati-kolo a Anati-kaona i hana. E like me ka nui refractory maka mea hope pili i ka hao a me kila hana, ua loa hoʻomano hoʻohana 'ia i loko o ka refractory castables ladles, precastings like porous pohakulepo, e noho hoʻopuni ana pohakulepo, ka hāʻuleʻana nozzles, ladle pani'ōmole. E like me ka iniiaiie i waeia o refractory maka mea, ka mea, ua lohe nui ia no hoi ma o ka likeʻole ma o na hana e like me foundry, petrochemical, pālolo a me ka incineration.
