Kaalshiyam carbide slag waa haraaga qashinka oo inta badan ka kooban kaalshiyam hydroxide ka dib marka la nadiifiyo kaalshiyam carbide si loo helo gaaska acetylene. Diyaarinta alaabada kiimikada ee ka soo baxda kaalshiyam slag waxaa loogu talagalay ujeeddada dib-u-warshadaynta kheyraadka, horumarinta hababka cagaaran iyo dhimista kharashyada tiknoolajiyada ayaa diiradda saari doonta cilmi-baarista mustaqbalka. HCMill (Guilin Hongcheng) waa soo-saarekaalshiyam hydroxidelaalaadiniyokalsiyumwarshad shiidi kaarboonaytQalabka. Kuwa soo socda ayaa ku bari doona habka loo diyaariyo nano calcium carbonate laga bilaabo slag carbide.

Kaarboonat-ka Nano-kaalshiyam waxaa si weyn loogu isticmaalaa caagga, balaastikada, sameynta warqadaha, khad iyo beeraha kale, iyadoo leh awood suuq oo weyn. Warshadaha, habka kaarboonat-ka waxaa inta badan loo isticmaalaa in lagu soo saaro kaarboonat-ka nano-kaalshiyam, CaO-na waxaa laga helaa kaarboonat-ka dhagaxa ah, kaas oo la dheefshiido oo la hakiyo Ca(OH)2, lagu daro wakiilka xakamaynta qaabka kiristaalka, ka gudubka kaarboonat-ka CO2, fuuq-baxa, iyo daaweynta dusha sare si loo helo kaarboonat-ka nano-kaalshiyam. Inta lagu jiro hawshan, gaaska qashinka ah (CO2), biyaha qashinka ah (biyaha cad) iyo haraaga qashinka ayaa la soo saari doonaa, taas oo ugu dambeyntii horseedi doonta hoos u dhac ku yimaada tayada badeecada waxayna yareyn doontaa ama xaqiijin doontaa saddexda qashin. Neef-baxa eber iyo hagaajinta tayada kaarboonat-ka nano-kaalshiyam ayaa ah arrimaha ugu muhiimsan, slag-ka kaarboonat-kana wuxuu si buuxda ula jaan qaadayaa fikradda ilaalinta deegaanka ee daaweynta qashinka qashinka.

Waqtigan xaadirka ah, diyaarinta nano-calcium carbonate laga bilaabo calcium carbide slag waxay inta badan ka kooban tahay saddex hab: kalsiyum slaking, hydrochloric acid leaching iyo ammonium chloride leaching. Li Rui et al. waxay isticmaaleen habka kalsiyum carbide iyo slaking cadaadiska si ay u sameeyaan slag calcium carbide ah oo la falgala gaaska CO2 ee falgalka kaarboonaynta cadaadiska leh si loo helo nano calcium carbonate oo wareegsan (60nm). Habkani ma aha oo kaliya inuu xalliyo wasakheynta gaaska qashinka CO2, laakiin sidoo kale wuxuu helaa badeecooyin qiimo sare leh; Liu Fei et al. waxay qaateen habka kalsiyum carbide, slag calcium carbide ah oo la asiidheeyay oo leh hydrochloric acid oo leh pH=8, waxayna sameeyeen falgal metathesis oo leh sodium carbonate. Natiijooyinka waxay muujiyeen in slag calcium carbide ah oo la asiidheeyay uu kor u qaadi doono slag calcium carbonate ah. Dhacitaanka isku-dhafka iyo laamaha la jarjaray ee qallafsan ugu dambeyntii waxay horseedaan slag aragonitic calcium carbonate ah oo leh qaybin isku mid ah iyo saamiga muuqaalka sare (30-60). Marka la barbardhigo walxaha ceeriin ee saafiga sare leh, waxaa la ogaaday in asiidhka nano-carbonic ee laga sameeyay calcium carbide slag Kalsiyumku wuxuu buuxiyaa heerka qaranka wuxuuna yareeyaa wasakhowga uu keeno slag carbide. Habkani wuxuu soo jeedinayaa waddo wax ku ool ah oo loogu talagalay diyaarinta nano-calcium carbonate.

Zhu Min iyo kuwa kale waxay isticmaaleen ammonium chloride si ay uga hortagaan slag calcium carbide, ka dibna waxay diyaariyeen nano-calcium carbonate iyadoo la adeegsanayo kaarboonaynta. Natiijooyinka waxay muujiyeen in markii isku-darka xalka ammonium chloride uu ahaa 8%, heerka isticmaalka slag calcium carbide uu ka badnaa 92%. Nooca nano-calcium carbonate (celceliska cabbirka walxaha waa 38nm), daahirnimada iyo caddaanka badeecada laga helay habkan waa ilaa 99.65% iyo 98.60% siday u kala horreeyaan, taas oo xallisa dhibaatada daahirnimada hoose iyo caddaanka liita ee ay keento wasakhda nano-calcium carbonate, waana xal wanaagsan oo loogu talagalay codsiyada warshadaha ee xiga. Jid wanaagsan ayaa la bixiyaa.

Marka la soo koobo, xaddi badan oo CO2 ah ayaa loo isticmaalaa diyaarinta kaalshiyamka carbonate slag, isticmaalka qiimaha sare leh ee kaalshiyamka carbide slag-na isla waqtigaas ayaa la heli karaa. Si kastaba ha ahaatee, way fududahay in la soo saaro biyaha wasakhda ah marka dusha sare wax laga beddelo waxyaabaha lagu daro kiimikada. Haddii aan la daweyn, waxay sababi doontaa wasakh labaad. Baahida dabagalka Tixgelin dhammaystiran oo dheeraad ah ayaa la siiyaa waxyaabaha ka soo baxa falcelinta si loo xaqiijiyo dib-u-warshadaynta slag-ka carbide.
