Calcium carbide slag ndi zinyalala zomwe zimapangidwa makamaka ndi calcium hydroxide pambuyo pa hydrolysis ya calcium carbide kuti ipange mpweya wa acetylene. Kukonzekera mankhwala ochokera ku carbide slag ndi cholinga chobwezeretsanso zinthu, ndipo kupanga njira zobiriwira komanso kuchepetsa ndalama zaukadaulo kudzakhala cholinga chachikulu cha kafukufuku wamtsogolo. HCMilling (Guilin Hongcheng) ndi wopangacalcium hydroxidekupalasandikashiamumphero yopukusira carbonatezida. Zotsatirazi zikuthandizani kudziwa njira yokonzekera nano calcium carbonate kuchokera ku carbide slag.

Nano-calcium carbonate imagwiritsidwa ntchito kwambiri mu rabara, mapulasitiki, kupanga mapepala, inki ndi madera ena, omwe ali ndi kuthekera kwakukulu pamsika. Mu mafakitale, njira yopangira carbonization imagwiritsidwa ntchito kwambiri popanga nano-calcium carbonate, ndipo CaO imapezeka poika calcium laimu, yomwe imagayidwa ndikuyimitsidwa Ca(OH)2 Crush, kuwonjezera chowongolera mawonekedwe a kristalo, kupititsa CO2 carbonization, kutaya madzi m'thupi, ndi kukonza pamwamba kuti mupeze nano-calcium carbonate. Panthawiyi, mpweya wotayira (CO2), madzi otayira (madzi oyera) ndi zotsalira za zinyalala zidzapangidwa, zomwe pamapeto pake zidzapangitsa kuti khalidwe la malonda lichepe ndikuchepetsa kapena kuzindikira zinyalala zitatu. Kutulutsa konse ndikuwongolera khalidwe la nano-calcium carbonate ndi nkhani zazikulu, ndipo carbide slag ikugwirizana kwathunthu ndi lingaliro loteteza chilengedwe lokonza zinyalala ndi zinyalala.

Pakadali pano, kukonzekera kwa nano-calcium carbonate kuchokera ku calcium carbide slag kumaphatikizapo njira zitatu: calcination slaking, hydrochloric acid leaching ndi ammonium chloride leaching. Li Rui ndi anzake adagwiritsa ntchito njira ya calcination ndi pressure slaking kuti calcium carbide slag igwirizane ndi CO2 flue gas mu pressurized carbonization reactor kuti ipeze spherical nano calcium carbonate (60nm). Njirayi sikuti imangothetsa kuipitsidwa kwa mpweya wa CO2, komanso imapanga zinthu zambiri zowonjezera; Liu Fei ndi anzake adagwiritsa ntchito njira ya hydrochloric acid leaching, acidified calcium carbide slag ndi hydrochloric acid yokhala ndi pH=8, ndipo adachita metathesis reaction ndi sodium carbonate. Zotsatira zake zidawonetsa kuti acidified calcium carbide slag ingalimbikitse calcium carbonate ndevu. Kupezeka kwa agglomeration ndi coarse forked nthambi pamapeto pake kumabweretsa aragonitic calcium carbonate ndevu zokhala ndi yunifolomu yogawa komanso high aspect ratio (30-60). Poyerekeza ndi zinthu zopangira zoyera kwambiri, zapezeka kuti nano-carbonic acid yopangidwa kuchokera ku calcium carbide slag. Calcium imakwaniritsa muyezo wadziko lonse ndipo imachepetsa kuipitsa komwe kumachitika chifukwa cha carbide slag. Njirayi ikupereka njira yothandiza yokonzekera nano-calcium carbonate.

Zhu Min ndi ena adagwiritsa ntchito ammonium chloride pochiza calcium carbide slag, kenako adakonza nano-calcium carbonate pogwiritsa ntchito carbonization. Zotsatira zake zidawonetsa kuti pamene kuchuluka kwa ammonium chloride solution kunali 8%, kuchuluka kwa calcium carbide slag komwe kumagwiritsidwa ntchito kunali kopitilira 92%. Mtundu wa nano-calcium carbonate (kukula kwa tinthu tating'onoting'ono ndi 38nm), kuyera ndi kuyera kwa chinthu chomwe chimapezeka kudzera mu njirayi ndi 99.65% ndi 98.60% motsatana, zomwe zimathetsa vuto la kuyera kochepa komanso kuyera koyipa komwe kumachitika chifukwa cha zodetsa za nano-calcium carbonate, ndipo ndi yankho labwino pakugwiritsa ntchito mafakitale ena. Njira yabwino yochitira zinthu imaperekedwa.

Mwachidule, kuchuluka kwa CO2 kumagwiritsidwa ntchito pokonza calcium carbonate slag, ndipo kugwiritsa ntchito calcium carbide slag yopindulitsa kwambiri kumatha kuchitika nthawi yomweyo. Komabe, n'zosavuta kupanga madzi otayira pamene pamwamba pake pasinthidwa ndi mankhwala ena. Ngati sichikonzedwa, chingayambitse kuipitsa kwina. Zofunikira zotsatirira Kuganiziranso kwakukulu kumaperekedwa ku zotsatira za zomwe zimachitika kuti carbide slag ibwezeretsedwenso.
