I-Calcium carbide slag iyinsalela yemfucuza ikakhulukazi eyakhiwe i-calcium hydroxide ngemva kwe-hydrolysis ye-calcium carbide ukuze kutholwe igesi ye-acetylene. Ukulungiswa kwemikhiqizo yamakhemikhali evela ku-carbide slag kuhloswe ukuvuselela kabusha izinsiza, futhi ukuthuthukiswa kwezinqubo eziluhlaza kanye nokwehliswa kwezindleko zobuchwepheshe kuzoba ukugxila kocwaningo lwesikhathi esizayo. I-HCMilling(Guilin Hongcheng) ingumkhiqizi wei-calcium hydroxideslakingfuthii-calciumumshini wokugaya i-carbonateimishini. Okulandelayo kuzokwethula ngenqubo yokulungisa i-nano calcium carbonate kusuka ku-carbide slag.

I-Nano-calcium carbonate isetshenziswa kakhulu enjolobeni, epulasitiki, ekwenzeni iphepha, uyinki neminye imikhakha, enamandla amakhulu emakethe. Embonini, indlela ye-carbonization isetshenziselwa ikakhulukazi ukukhiqiza i-nano-calcium carbonate, futhi i-CaO itholakala ngokubala i-limestone, egaywe futhi imiswe okwesikhashana i-Ca(OH) 2 Crush, engeza i-crystal form control agent, idlule i-CO2 carbonization, ukuphelelwa amanzi emzimbeni, kanye nokwelashwa kwendawo ukuze uthole i-nano-calcium carbonate. Phakathi nale nqubo, kuzokwenziwa igesi engcolile (CO2), amanzi angcolile (amanzi amhlophe) kanye nezinsalela zemfucuza, okuzogcina kuholele ekwehleni kwekhwalithi yomkhiqizo futhi kunciphise noma kuqaphele ukuthi imfucumfucu emithathu ekhishwa yi-Zero kanye nokuthuthukisa ikhwalithi ye-nano-calcium carbonate yizinkinga ezibalulekile, futhi i-carbide slag ihambisana ngokuphelele nomqondo wokuvikelwa kwemvelo wokuphatha imfucuza ngemfucuza.

Njengamanje, ukulungiswa kwe-nano-calcium carbonate kusuka ku-calcium carbide slag ikakhulukazi kuhlanganisa izindlela ezintathu: i-calcination slaking, i-hydrochloric acid leaching kanye ne-ammonium chloride leaching. U-Li Rui et al. wasebenzisa umzila wenqubo wokubala kanye ne-pressure slaking ukwenza i-calcium carbide slag isabelane ne-CO2 flue gas kureactor ecindezelwe ye-carbonization ukuze kutholwe i-spherical nano calcium carbonate (60nm). Le nqubo ayixazululi kuphela ukungcoliswa kwegesi engcolile ye-CO2, kodwa futhi ithola imikhiqizo ephezulu ye-value-added; U-Liu Fei et al. yamukela inqubo ye-hydrochloric acid leaching, i-acidified calcium carbide slag ene-hydrochloric acid ene-pH=8, futhi yenza ukusabela kwe-metathesis nge-sodium carbonate. Imiphumela yabonisa ukuthi i-calcium carbide slag ene-asidi ingakhuthaza amadevu e-calcium carbonate Ukwenzeka kwe-agglomeration namagatsha amaholoholo anemfoloko ekugcineni kuholela kumadevu e-aragonitic calcium carbonate anokusabalalisa okufanayo kanye ne-aspect ratio ephezulu (30-60). Uma kuqhathaniswa nezinto eziluhlaza ezihlanzekile, kutholakala ukuthi i-nano-carbonic acid elungiselelwe kusuka ku-calcium carbide slag I-calcium ihlangabezana nezinga kazwelonke futhi inciphisa ukungcola okubangelwa i-carbide slag. Le nqubo iphakamisa umzila wenqubo osebenzayo wokulungiswa kwe-nano-calcium carbonate.

U-Zhu Min nabanye basebenzisa i-ammonium chloride ukuze balungise i-calcium carbide slag, base belungisa i-nano-calcium carbonate nge-carbonization. Imiphumela yabonisa ukuthi lapho ukugcwala kwesisombululo se-ammonium chloride kuma-8%, izinga lokusebenzisa i-calcium carbide slag lalingaphezu kwama-92%. Thayipha i-nano-calcium carbonate (isilinganiso sosayizi wezinhlayiyana singama-38nm), ubumsulwa kanye nobumhlophe bomkhiqizo otholwe yile nqubo kufika ku-99.65% no-98.60% ngokulandelana, okuxazulula inkinga yokuhlanzeka okuphansi kanye nobumhlophe obumpofu obubangelwa ukungcola ku-nano-calcium carbonate, futhi kuyisixazululo esihle senqubo yezinhlelo zokusebenza ezilandelanayo zezimboni zinikezwa.

Ngamafuphi, inani elikhulu le-CO2 lisetshenziselwa ukulungiswa kwe-calcium carbonate slag, futhi ukusetshenziswa kwe-value-added ye-calcium carbide slag kungenziwa ngesikhathi esifanayo. Nokho, kulula ukukhiqiza amanzi angcolile lapho ingaphezulu lilungiswa ngezithasiselo zamakhemikhali. Uma ingelashwa, izodala ukungcola kwesibili. Izidingo zokulandelela Ukucutshungulwa okubanzi kunikezwa emikhiqizweni yokusabela ukuze kuqashwe kabusha i-carbide slag.
