I-Calcium carbide slag yinkunkuma eyintsalela equlunqwe kakhulu yi-calcium hydroxide emva kwe-hydrolysis ye-calcium carbide ukufumana igesi ye-acetylene. Ukulungiswa kweemveliso zeekhemikhali ezivela kwi-carbide slag yinjongo yokubuyisela kwakhona izibonelelo, kunye nokuphuhliswa kweenkqubo eziluhlaza kunye nokunciphisa iindleko zobuchwepheshe kuya kuba kugxininiso lophando lwexesha elizayo. HCMilling(Guilin Hongcheng) ngumvelisi wecalcium hydroxideslakingkwayecalciumilitye lokusila icarbonateizixhobo. Oku kulandelayo kuya kukwazisa kwinkqubo yokulungiselela i-nano calcium carbonate kwi-carbide slag.

I-Nano-calcium carbonate isetyenziswa kakhulu kwirabha, iiplastiki, ukwenza iphepha, i-inki kunye namanye amasimi, anamandla amakhulu okuthengisa. Kwishishini, indlela ye-carbonization isetyenziselwa ukuvelisa i-nano-calcium carbonate, kwaye i-CaO ifumaneka nge-calcining limestone, egayiweyo kwaye imisiwe i-Ca (OH) 2 Crush, yongeza i-agent ye-crystal form control, idlulise i-CO2 carbonization, i-dehydration, kunye nonyango oluphezulu ukuze ufumane i-nano-calcium carbonate. Ngethuba le nkqubo, i-gas yenkunkuma (CO2), amanzi amdaka (amanzi amhlophe) kunye nentsalela yenkunkuma iya kuveliswa, eya kuthi ekugqibeleni ikhokelele ekunciphiseni umgangatho wemveliso kwaye inciphise okanye iqonde inkunkuma emithathu Ukukhutshwa kwe-Zero kunye nokuphucula umgangatho we-nano-calcium carbonate yimiba ephambili, kunye ne-carbide slag ihambelana ngokupheleleyo nengcamango yokukhusela indalo yokuphatha inkunkuma ngenkunkuma.

Okwangoku, ukulungiswa kwe-nano-calcium carbonate ukusuka kwi-calcium carbide slag ikakhulu kubandakanya iindlela ezintathu: i-calcination slaking, i-hydrochloric acid leaching kunye ne-ammonium chloride leaching. U-Li Rui et al. kusetyenziswe indlela yenkqubo yokubala kunye noxinzelelo lwe-slag ukwenza i-calcium carbide slag iphendule nge-CO2 flue gas kwi-pressurized carbonization reactor ukufumana i-spherical nano calcium carbonate (60nm). Le nkqubo ayisombululi kuphela ungcoliseko lwegesi yenkunkuma ye-CO2, kodwa ikwafumana neemveliso zexabiso eliphezulu; ULiu Fei et al. Yamkela inkqubo ye-hydrochloric acid leaching, i-acidified calcium carbide slag ene-hydrochloric acid ene-pH = 8, kwaye iqhube i-metathesis reaction kunye ne-sodium carbonate. Iziphumo zabonisa ukuba i-acidified calcium carbide slag ingakhuthaza amabhovu e-calcium carbonate Ukwenzeka kwe-agglomeration kunye namasebe arhabaxa efolokhwe ekugqibeleni kukhokelele kwi-aragonitic calcium carbonate whiskers kunye nokusabalalisa okufanayo kunye nomlinganiselo ophezulu (30-60). Xa kuthelekiswa nezinto ezicocekileyo ezicocekileyo, kufunyenwe ukuba i-nano-carbonic acid elungiselelwe ukusuka kwi-calcium carbide slag I-calcium idibana nomgangatho wesizwe kwaye inciphisa ukungcola okubangelwa yi-carbide slag. Le nkqubo iphakamisa indlela yenkqubo esebenzayo yokulungiswa kwe-nano-calcium carbonate.

UZhu Min kunye nabanye basebenzisa i-ammonium chloride ukuthambisa i-calcium carbide slag, baze balungiselele i-nano-calcium carbonate nge-carbonization. Iziphumo zabonisa ukuba xa ukuxutywa kwesisombululo se-ammonium chloride kwakuyi-8%, izinga lokusetyenziswa kwe-calcium carbide slag lalingaphezu kwama-92%. Uhlobo lwe-nano-calcium carbonate (i-avareji ye-particle size yi-38nm), ukucoceka kunye nobumhlophe bemveliso efunyenwe yile nkqubo ifikelela kwi-99.65% kunye ne-98.60% ngokulandelanayo, oyisombulula ingxaki yokuhlambuluka okuphantsi kunye nomhlophe ompofu obangelwa ukungcola kwi-nano-calcium carbonate, kwaye isisombululo esihle kwizicelo zenkqubo ye-industrial elandelayo inikezelwa.

Isishwankathelo, isixa esikhulu se-CO2 sisetyenziselwa ukulungiswa kwe-calcium carbonate slag, kwaye ukusetyenziswa kwexabiso eliphezulu kwe-calcium carbide slag kunokufezekiswa ngexesha elifanayo. Nangona kunjalo, kulula ukuvelisa amanzi amdaka xa umphezulu uguqulwa ngezongezo zekhemikhali. Ukuba ayiphathwa, iya kubangela ungcoliseko lwesibini. Iimfuno zokulandelisa Uqwalaselo olungaphaya olubanzi lunikezelwa kwiimveliso zendlela yokusabela ukuze kuqatshelwe ukwenziwa ngokutsha kwe-carbide slag.
