I-calcium carbide slag iyinsalela yemfucuza eyakhiwa kakhulu yi-calcium hydroxide ngemva kokuyi-hydrolysis ye-calcium carbide ukuze kutholakale igesi i-acetylene. Ukulungiswa kwemikhiqizo yamakhemikhali evela ku-carbide slag kuhloswe ngenhloso yokuvuselela izinsiza, futhi ukuthuthukiswa kwezinqubo eziluhlaza kanye nokunciphisa izindleko zobuchwepheshe kuzoba yinto ezogxilwa ocwaningweni lwesikhathi esizayo. I-HCMilling (Guilin Hongcheng) ingumkhiqizi we-i-calcium hydroxidei-slakingfuthii-calciumumshini wokugaya i-carbonateimishini. Lokhu okulandelayo kuzokwethula inqubo yokulungiselela i-nano calcium carbonate kusuka ku-carbide slag.

I-Nano-calcium carbonate isetshenziswa kabanzi enjolobeni, epulasitikini, ekwenzeni amaphepha, kuyinki nakwezinye izindawo, futhi inamandla amakhulu emakethe. Embonini, indlela yokwenza i-carbonization isetshenziswa kakhulu ukukhiqiza i-nano-calcium carbonate, kanti i-CaO itholakala ngokufaka i-calcining limestone, egaywayo futhi imiswe i-Ca(OH)2 Crush, ingeze i-crystal form control agent, idlulise i-CO2 carbonization, i-dehydration, kanye nokwelashwa kwendawo ukuze kutholakale i-nano-calcium carbonate. Phakathi nale nqubo, kuzokhiqizwa igesi engcolile (CO2), amanzi angcolile (amanzi amhlophe) kanye nezinsalela zemfucuza, okuzogcina kuholele ekwehleni kwekhwalithi yomkhiqizo futhi kuncishiswe noma kutholakale imfucuza emithathu. Ukukhishwa kwe-Zero kanye nokuthuthukisa ikhwalithi ye-nano-calcium carbonate yizinkinga ezibalulekile, futhi i-carbide slag ihambisana ngokuphelele nomqondo wokuvikela imvelo wokuphatha imfucuza ngemfucuza.

Njengamanje, ukulungiswa kwe-nano-calcium carbonate kusuka ku-calcium carbide slag kuhlanganisa kakhulu izindlela ezintathu: i-calcination slaking, i-hydrochloric acid leaching kanye ne-ammonium chloride leaching. ULi Rui nabanye basebenzise indlela yenqubo ye-calcination kanye ne-pressure slaking ukwenza i-calcium carbide slag isabele negesi ye-CO2 flue ku-reactor ye-carbonization ecindezelwe ukuze kutholakale i-spherical nano calcium carbonate (60nm). Le nqubo ayixazululi nje kuphela ukungcola kwegesi engcolile ye-CO2, kodwa futhi ithola imikhiqizo enenani eliphezulu; uLiu Fei nabanye bamukele inqubo ye-hydrochloric acid leaching, i-acidified calcium carbide slag ene-hydrochloric acid ene-pH=8, futhi benze i-metathesis reaction ne-sodium carbonate. Imiphumela ikhombisile ukuthi i-acidified calcium carbide slag izokhuthaza ama-calcium carbonate whiskers. Ukuvela kwama-agglomeration namagatsha aqinile ahlanganisiwe ekugcineni kuholela kuma-aragonitic calcium carbonate whiskers anokusatshalaliswa okufanayo kanye ne-high aspect ratio (30-60). Uma kuqhathaniswa nezinto zokusetshenziswa ezihlanzekile kakhulu, kutholakale ukuthi i-nano-carbonic acid elungiselelwe kusuka ku-calcium carbide slag. I-calcium ihlangabezana nezindinganiso zikazwelonke futhi inciphisa ukungcola okubangelwa yi-carbide slag. Le nqubo iphakamisa indlela yenqubo ephumelelayo yokulungiselela i-nano-calcium carbonate.

UZhu Min nabanye basebenzise i-ammonium chloride ukwelapha i-calcium carbide slag kusengaphambili, base belungisa i-nano-calcium carbonate nge-carbonization. Imiphumela ibonise ukuthi lapho ukuhlushwa kwesisombululo se-ammonium chloride kungu-8%, izinga lokusetshenziswa kwe-calcium carbide slag lalingaphezu kuka-92%. Uhlobo lwe-nano-calcium carbonate (usayizi wezinhlayiya ojwayelekile ungu-38nm), ubumsulwa kanye nobumhlophe bomkhiqizo otholwe ngale nqubo kufinyelela ku-99.65% kanye no-98.60% ngokulandelana, okuxazulula inkinga yobumsulwa obuphansi kanye nobumhlophe obubi obubangelwa ukungcola kwe-nano-calcium carbonate, futhi kuyisisombululo esihle sezicelo zezimboni ezilandelayo. Kunikezwa indlela enhle yenqubo.

Ngamafuphi, inani elikhulu le-CO2 lisetshenziswa ekulungiseleleni i-calcium carbonate slag, futhi ukusetshenziswa kwe-calcium carbide slag enenani eliphezulu kungatholakala ngesikhathi esifanayo. Kodwa-ke, kulula ukukhiqiza amanzi angcolile lapho ubuso buguqulwa yizithasiselo zamakhemikhali. Uma bungaphathwa, kuzobangela ukungcola kwesibili. Izidingo zokulandelela Kucatshangelwa kabanzi ngemikhiqizo elandelanayo yokusabela ukuze kuqaliswe ukuphinda kusetshenziswe i-carbide slag.
