Ke Kaʻina Hana ʻana i nā Pilikia Pale Alkali
Hiki i nā pōhaku lepo alkaline i nā mahana kiʻekiʻe ke hana me ka alkali metala oxide i hoʻokumu ʻia i ka viscosity kiʻekiʻe o ka pae wai, e hana ana i kahi papa o ka glaze i hoʻololi ʻia i ke ʻano o ka papa, e uhi ana i ka ʻili o nā pores ʻili pōhaku pōhaku, e pale i ka infiltration a me ka erosion o ka alkali. mea hooheheeia metala, loaa ke kumu o ka erosion alkali. ʻO ka poloka kūpaʻa alkali e pili ana i ka pālolo pale pale pale haʻahaʻa haʻahaʻa e like me ka mea nui, i hana ʻia me ka alumini i loko o ka ʻōnaehana kiln sima a he kūpaʻa maikaʻi ka alkali corrosion a me ka conductivity thermal haʻahaʻa.
Hoʻokaʻawale ʻana i nā pōhaku lepo alkaline
Hiki ke hoʻokaʻawale ʻia nā pōhaku lepo alkali i ʻehā mau ʻano: ʻo nā pōhaku kūʻokoʻa alkali maʻamau, ka ikaika kiʻekiʻe alkali kūpaʻa ahi, ʻano vault ʻano alkali kūʻokoʻa poloka a me ka thermal insulation type alkali resistant block.
Hoʻohana nui ʻia nā pōhaku lepo alkali maʻamau i loko o ka umu kiln preheater a me ka umu decomposing ʻekolu manawa.
Hoʻohana nui ʻia ka ikaika kiʻekiʻe alkali pale ahi i ka cement kiln preheater, decomposed furnace, ʻekolu ea ducts, vertical rising flue, cyclone cylinder.
Hoʻohana nui ʻia ʻo Vault type alkali resistant block i ka cement kiln preheater a me ka decomposing umu ʻekolu manawa.
Thermal insulation type alkali resistant block he alkali corrosion resistance haʻahaʻa haʻahaʻa thermal conductivity, loaʻa ka wela insulation hana o ka silica alumina refractory huahana.
