nhazi ọkwa

Dị ka chemical mejupụtara nke ngwakọta bụ kewapụta ikuku (tumadi esịnede oxides nke magnesium na calcium) na hydrate (nwere buru ibu nke ígwè oxides, aluminum, na sịlịkọn). Na ụlọ ọrụ, na-eji akpụ lime na quicklime ewu ntụ ntụ. Nke ikpeazụ a na-kewara abụọ ụdị. First - lime n'ala quicklime. The abụọ ụdị na-emepụta site na ngwa nke a pụrụ iche technology. Imenyụ usoro Magnesia, calcium lime na dolomitic eji a ole na ole nke mmiri nwetara slaked wayo (hydrated wayo). E nwere ndị ọzọ na ụdị. A na-agụnye, akpan akpan, na-agụnye perchloric, na soda-wayo.

mmepụta

Arụpụtara lime maka ewu iji eke calcium na magnesium umu. Ha tumadi na-agụnye carbonate nke calcium na magnesium. Na ha mejupụtara na-agụnye clays na ájá admixtures. N'oge kwes nhazi (site kpo oku) na a oku ka okpomọkụ nke 800 na 1200 degrees calcium-magnesium nkume amalite amalite irekasị. Dị ka a N'ihi nke a usoro emepụta magnesium oxide (MgO) na calcium (CaO) na carbon dioxide.

The technology maka amị ezi egweri nke ngwakọta

Wayo n'ala quicklime nwetara site egweri nke ngwakọta na a ot bọl mills. Ọrụ ha rụrụ na a mechiri emechi okirikiri na ịmata a chọrọ urughuru size separator. Mgbe ụfọdụ, ndị unit na-enịm ke abụọ separators na usoro. Nke a budata enwekwu arụpụtaghị. Ka ụbọchị, ajụjụ bibiri lime insufficiently mepụtara. The nhọrọ usoro nke-egweri mills na sekit na sekit dị mkpa iji tụlee isi ogo amịkpọ nke ihe onwunwe (ike, na-ajụ ma ọ bụ myagkoobozhzhenny ngwaahịa).

The compound nwekwara ike nro mmiri na ịkpali ugbu nime ya organic bekee na ngwaahịa. Ọzọkwa, na ojiji nke ngwa lime enye eke neutralizing acidic na wastewater. Na ugbo, mgbe na kọntaktị na Ona compound acidity eliminates emerụ akuku osisi. Quicklime enriches ala na calcium. A na-enwekwu ndị workability nke ụwa, accelerates ire ere nke humus. N'otu oge ahụ ọ na-ebelata mkpa nitrogen fatịlaịza ngwa na nnukwu doses. The hydrated ngwakọta na-eji na ọkụkọ na anụ ụlọ maka nri. Ewepụ enweghị calcium na ihe oriri. Ọzọkwa, compound eji maka rụọ izugbe ike na ọnọdụ mgbe idebe na ozuzu anụ ụlọ. Na chemical ụlọ ọrụ hydrated wayo na adsorbents eji maka nkwadebe nke Fluoride na calcium hydrochloride. Na Petrochemical ụlọ ọrụ compound neutralizes na acid sludge na-eme dị ka a reagent tumadi inorganic na organic njikọ. Wayo na ọtụtụ-eji na-ewu. Nke a bụ n'ihi na elu na gburugburu ebe obibi ihe.
