Zvidhinha zve alumina zvine alumina yakawanda zvinogadzirwa ne bauxite yepamusoro-soro sezvinhu zvikuru zvinoshandiswa pakuputira, kudzvanywa, kuomeswa uye kupiswa pakupisa kwakanyanya. Izvi zvinhu zvinoramba zvichishandiswa pakuputika.

2. Zvidhinha zve alumina zvakawanda zvinoshandiswa muzvitofu zvinoputika zviri kupi?

Zvidhinha zvealuminium zvakakwirira zvinovakwa pachigadziko chechoto chechoto cheblast. Chidhinha chechoto chiri pamusoro pechoto cheblast. Upamhi hwacho hunokura zvishoma nezvishoma kubva kumusoro kusvika pasi kuti huenderane nekuwedzera kwekupisa kwechaji uye kuderedza kukweshana kwemadziro echoto pachaji. Muviri wechoto unogara muchoto cheblast. 50%-60% yehurefu hunoshanda. Munzvimbo iyi, jira rechoto rinofanira kusangana nezvinodiwa zvakadaro, uye hunhu hwezvidhinha zvealuminium zvakawanda ndezvekusimba kwakanyanya, tembiricha yakanyanya kunyorova pasi pemutoro, kuramba acid, kuramba alkali, kuramba kwakasimba kukurwa kweslag, uye kuramba kupfeka kwakanaka. Inogona kugutsa, saka yakakodzera kwazvo kuti muviri wechoto cheblast ufukidzwe nezvidhinha zvealuminium zvakawanda.

Zviri pamusoro apa isumo yezvidhinha zve alumina zvine runako rwepamusoro zvezvitofu zvinoputika. Nzvimbo yekuisa jira muchoto chinoputika yakaoma uye kune mhando dzakawanda dzezvinhu zvinoramba kushandiswa. Zvidhinha zve alumina zvine runako rwepamusoro ndechimwe chazvo. Kune zvirevo zvitatu kusvika zvishanu zvezvidhinha zve alumina zvine runako rwepamusoro zvinoshandiswa. Zvidhinha zve alumina zvine runako rwaRobert zvinogona kushandiswa muzvitofu zvakasiyana-siyana. Kana zvichidikanwa, ndapota taura nesu.
