I-calcium oxide, enefomula yamakhemikhali i-CaO2, ikhiqizwa ngokubola i-limestone noma amagobolondo aqukethe i-calcium carbonate ngokushisa ngokuwafudumeza ngaphezu kwama-degree Celsius angu-825 kuhhavini we-lime. Le nqubo, ebizwa ngokuthi i-calcination noma i-lime burning, ikhipha i-carbon dioxide, ishiye i-quicklime. I-Quicklime ayizinzile futhi ngaphandle kokuthi ifakwe amanzi ukuze yakhe i-lime paste noma i-lime mortar, izosabela ngokuzenzakalelayo ne-CO2 emoyeni njengoba iphola, ekugcineni iguquke ngokuphelele ibe yi-calcium carbonate.

Ukusetshenziswa kwe-calcium oxide

I-calcium oxide inezinhlobo eziningi zezicelo emikhakheni eminingi ngenxa yokuguquguquka kwayo. Emkhakheni wokwakha, i-calcium oxide ingasetshenziswa njengezinto zokwakha ukuthuthukisa umphumela wokubeka ngokushesha wesamente. Ezinqubweni zensimbi, isebenza njengokushintshashintsha ukusiza ukuncibilikisa izinsimbi. Ekucubungulweni kwamafutha emifino, i-calcium oxide isebenza njenge-ejenti yokususa umbala ukuthuthukisa ikhwalithi yemikhiqizo yamafutha. Ngaphezu kwalokho, ingasetshenziswa futhi ekuthuthukiseni inhlabathi ukwandisa ukuzala kwenhlabathi, njengesithwali semithi yokuthuthukisa ukuzinza kanye nokutholakala kwemithi, kanye nomanyolo we-calcium wokukhuthaza ukukhula kwezitshalo.

I-calcium oxide isetshenziselwa futhi ukwenza izinto ezimelana nokushisa okuphezulu kwezinto. Njenge-desiccant, ingamunca umswakama emoyeni futhi igcine izinto zomile. Ekuhlanzweni kwamanzi amdaka, i-calcium oxide isetshenziselwa ukwelapha amanzi amdaka ane-acid kanye nokulungisa ukungcola ukuze kuhlanzwe ikhwalithi yamanzi. Ngaphezu kwalokho, isetshenziselwa futhi ukwenza amakhemikhali anjenge-calcium carbide, i-soda ash, kanye ne-bleaching powder.

Ukugeleza kokucubungula i-calcium oxide

Ukugeleza kokucubungula kwe-calcium oxide kuhlanganisa kakhulu ukugaywa kwe-limestone kanye nokugaywa kwe-calcium oxide. Ngemva kokuba i-limestone ichotshoziwe futhi ihlolwe, ithunyelwa ku-lime oven ukuze i-calcination. Ekushiseni okuphezulu okungu-900 kuya ku-1200 degrees Celsius, i-limestone iyabola ukuze ikhiqize i-calcium oxide kanye ne-carbon dioxide. Ngemva kokuba i-calcium oxide e-calcined ipholile futhi ichotshoziwe, umkhiqizo wokuqala we-calcium oxide ungatholakala. Ukuze kutholakale i-calcium oxide powder ecolekile, kudingeka imishini yokwenza i-powder yobungcweti. Umshini wokwenza i-calcium oxide powder we-mesh engu-200 udlala indima ebalulekile kulesi sixhumanisi. Lo mshini ungaqhubeka nokugaya izinhlayiya ze-calcium oxide zibe yi-200 mesh fine powder ukuze kuhlangatshezwane nezidingo ezahlukene zokusetshenziswa.

Isingeniso somshini wokwenza i-powder ye-calcium oxide ene-mesh engu-200

Umshini wokwenza i-powder we-calcium oxide one-mesh engu-200 uyimishini yokugaya i-powder ye-calcium oxide yobungcweti eyasungulwa yi-Guilin Hongcheng Mining Equipment Manufacturing Co., Ltd. Ingagaya ngempumelelo izinhlayiya ze-calcium oxide zibe yi-200 mesh fine powder, futhi ingalungisa usayizi wezinhlayiya eziphumayo kusuka ku-80 mesh kuya ku-400 mesh ngokwezidingo zangempela zokukhiqiza. Imishini ingandisa umthamo wokukhiqiza ngaphezu kuka-40% futhi inciphise izindleko zokusetshenziswa kwamandla eyunithi ngaphezu kuka-30%. Inomsindo ophansi, ukusebenza kahle kokuhlukanisa okuphezulu, amandla amakhulu okudlulisa kanye nokunemba okuphezulu kokuhlukanisa. Ingumshini wokugaya omusha omuhle kakhulu wokunciphisa umsindo onobungane nemvelo. Ngesikhathi esifanayo, imishini ifakwe ama-motor athuthukile nezinhlelo zokulawula, ezingafeza ukukhiqizwa okuzenzakalelayo futhi zithuthukise ukusebenza kahle kokukhiqiza.

Impuphu ye-calcium oxide ene-mesh engu-200 kaGuilin HongchengUmshini wokwenza udlala indima ebalulekile ekucutshungulweni kwe-calcium oxide. Ngokusebenzisa ukugaya okuphumelelayo, ungagaya izinhlayiya ze-calcium oxide zibe yimpuphu ecolekileyo engu-200 enemeshi ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo lokusebenza. Ukuze uthole amapharamitha ezobuchwepheshe engeziwe kanye nesilinganiso sakamuva salo mshini, sicela usithinte ukuze uthole imininingwane.
