I-calcium carbide slag yintsalela yenkunkuma eyenziwe ikakhulu yi-calcium hydroxide emva kwe-hydrolysis ye-calcium carbide ukuze ifumane igesi ye-acetylene. Ukulungiswa kweemveliso zeekhemikhali ezivela kwi-carbide slag kujoliswe ekusetyenzisweni kwakhona kwezixhobo, kwaye uphuhliso lweenkqubo eziluhlaza kunye nokunciphisa iindleko zobuchwepheshe kuya kuba yinto ephambili kuphando lwexesha elizayo. I-HCMilling (Guilin Hongcheng) ngumvelisi we-i-calcium hydroxidei-slakingkwayeikhalsiyamumzi-mveliso wokugaya i-carbonateizixhobo. Oku kulandelayo kuza kukwazisa ngenkqubo yokulungiselela i-nano calcium carbonate kwi-carbide slag.

I-Nano-calcium carbonate isetyenziswa kakhulu kwirabha, iiplastiki, ukwenza iphepha, i-inki kunye nezinye iindawo, ezinokubakho okukhulu kwimarike. Kwishishini, indlela yokwenza i-carbonization isetyenziswa kakhulu ukuvelisa i-nano-calcium carbonate, kwaye i-CaO ifunyanwa ngokufaka i-calcining limestone, egaywayo kwaye ixhonywe i-Ca(OH)2 Crush, yongeza i-crystal form control agent, idlulise i-CO2 carbonization, i-dehydration, kunye nonyango lomphezulu ukuze kufunyanwe i-nano-calcium carbonate. Ngexesha lale nkqubo, kuya kuveliswa igesi yenkunkuma (CO2), amanzi amdaka (amanzi amhlophe) kunye nentsalela yenkunkuma, eya kuthi ekugqibeleni ikhokelele ekunciphiseni umgangatho wemveliso kwaye inciphise okanye ifezekise inkunkuma ezintathu. Ukukhutshwa kwe-Zero kunye nokuphucula umgangatho we-nano-calcium carbonate zezona zinto ziphambili, kwaye i-carbide slag ihambelana ngokupheleleyo nombono wokhuseleko lokusingqongileyo wokuphatha inkunkuma ngenkunkuma.

Okwangoku, ukulungiswa kwe-nano-calcium carbonate kwi-calcium carbide slag kubandakanya ikakhulu iindlela ezintathu: i-calcination slaking, i-hydrochloric acid leaching kunye ne-ammonium chloride leaching. ULi Rui nabanye basebenzise indlela yenkqubo ye-calcination kunye ne-pressure slaking ukwenza i-calcium carbide slag isabele ngegesi ye-CO2 flue kwi-reactor ye-carbonization ecinezelweyo ukuze kufunyanwe i-spherical nano calcium carbonate (60nm). Le nkqubo ayisombululi nje kuphela ungcoliseko lwegesi yenkunkuma ye-CO2, kodwa ikwafumana iimveliso ezinexabiso eliphezulu; uLiu Fei nabanye bamkele inkqubo ye-hydrochloric acid leaching, i-acidified calcium carbide slag ene-hydrochloric acid ene-pH=8, kwaye benze i-metathesis reaction ne-sodium carbonate. Iziphumo zibonise ukuba i-acidified calcium carbide slag iya kukhuthaza i-calcium carbonate whiskers. Ukuvela kwe-agglomeration kunye namasebe aqinileyo ekugqibeleni kukhokelela kwi-aragonitic calcium carbonate whiskers enokusasazwa okufanayo kunye nomlinganiselo ophezulu (30-60). Xa kuthelekiswa nezinto eziluhlaza ezicocekileyo kakhulu, kufunyaniswe ukuba i-nano-carbonic acid eyenziwe nge-calcium carbide slag. I-calcium ihlangabezana nomgangatho wesizwe kwaye iyanciphisa ungcoliseko olubangelwa yi-carbide slag. Le nkqubo icebisa indlela esebenzayo yokulungiselela i-nano-calcium carbonate.

UZhu Min nabanye basebenzise i-ammonium chloride ukunyanga i-calcium carbide slag, baze balungiselela i-nano-calcium carbonate nge-carbonization. Iziphumo zibonise ukuba xa uxinzelelo lwesisombululo se-ammonium chloride lwaluyi-8%, izinga lokusetyenziswa kwe-calcium carbide slag lalingaphezulu kwe-92%. Uhlobo lwe-nano-calcium carbonate (ubungakanani obuqhelekileyo bezinto ezisetyenziswayo yi-38nm), ubunyulu kunye nobumhlophe bemveliso efunyenwe yile nkqubo bufikelela kwi-99.65% kunye ne-98.60% ngokulandelelana, nto leyo esombulula ingxaki yobunyulu obuphantsi kunye nobumhlophe obubi obubangelwa kukungcola kwi-nano-calcium carbonate, kwaye sisisombululo esilungileyo kwizicelo zoshishino ezilandelayo. Indlela elungileyo yenkqubo iyabonelelwa.

Ngamafutshane, isixa esikhulu se-CO2 sisetyenziswa ekulungiseleleni i-calcium carbonate slag, kwaye ukusetyenziswa kwe-calcium carbide slag enexabiso eliphezulu kunokuphunyezwa ngaxeshanye. Nangona kunjalo, kulula ukuvelisa amanzi amdaka xa umphezulu uguqulwa zizithako zeekhemikhali. Ukuba awunyangwa, uya kubangela ungcoliseko lwesibini. Iimfuno zokulandelela Ingqwalasela ebanzi ngakumbi inikwa kwimveliso yempendulo ukuze kuqinisekiswe ukuphinda kusetyenziswe i-carbide slag.
