Calcium carbide slag ndi zotsalira za zinyalala zomwe zimapangidwa makamaka ndi calcium hydroxide pambuyo pa hydrolysis ya calcium carbide kuti ipeze mpweya wa acetylene.Kukonzekera kwa mankhwala opangidwa ndi carbide slag ndi cholinga chobwezeretsanso zinthu, ndipo kupititsa patsogolo njira zobiriwira ndi kuchepetsa ndalama zamakono kudzakhala cholinga cha kafukufuku wamtsogolo.HCMilling(Guilin Hongcheng) ndi wopangacalcium hydroxideslakingndicalciumcarbonate mpherozida.Zotsatirazi zikuwonetsani momwe mungakonzekerere nano calcium carbonate kuchokera ku carbide slag.

Nano-calcium carbonate imagwiritsidwa ntchito kwambiri mu mphira, mapulasitiki, kupanga mapepala, inki ndi madera ena, omwe ali ndi mwayi waukulu wamsika.M'makampani, njira ya carbonization imagwiritsidwa ntchito makamaka popanga nano-calcium carbonate, ndipo CaO imapezedwa ndi calcining laimu, yomwe imagayidwa ndikuyimitsidwa Ca (OH) 2 Crush, kuwonjezera kristalo wolamulira mawonekedwe, kudutsa CO2 carbonization, kutaya madzi m'thupi, ndi pamwamba. chithandizo kuti mupeze nano-calcium carbonate.Panthawiyi, mpweya wotayira (CO2), madzi otayira (madzi oyera) ndi zotsalira za zinyalala zidzapangidwa, zomwe pamapeto pake zidzapangitsa kuchepa kwa khalidwe lazogulitsa ndikuchepetsa kapena kuzindikira zinyalala zitatu zotulutsa Zero ndikuwongolera khalidwe la nano-calcium. carbonate ndiye nkhani zazikulu, ndipo carbide slag ikugwirizana kwathunthu ndi lingaliro lachitetezo cha chilengedwe chochitira zinyalala ndi zinyalala.

Pakali pano, kukonzekera kwa nano-calcium carbonate kuchokera ku calcium carbide slag makamaka kumaphatikizapo njira zitatu: calcination slaking, hydrochloric acid leaching ndi ammonium chloride leaching.Li Rui et al.adagwiritsa ntchito njira yowerengetsera ndi kukakamiza kuti apangitse calcium carbide slag kuchita ndi mpweya wa CO2 flue mu choyatsira choponderezedwa cha carbonization kuti apeze ozungulira nano calcium carbonate (60nm).Njirayi sikuti imangothetsa kuipitsidwa kwa gasi wa CO2 wonyansa, komanso imapeza zinthu zapamwamba zowonjezera;Liu Fei et al.anatengera hydrochloric asidi leaching ndondomeko, acidified kashiamu carbide slag ndi hydrochloric asidi ndi pH = 8, ndipo anachita metathesis anachita ndi sodium carbonate.Zotsatira zinawonetsa kuti acidified calcium carbide slag ingalimbikitse ndevu za calcium carbonate Kupezeka kwa nthambi zosakanikirana ndi zomangira zolimba pamapeto pake kumabweretsa ndevu za aragonitic calcium carbonate zomwe zimagawidwa mofanana ndi chiŵerengero chapamwamba (30-60).Poyerekeza ndi zopangira zoyera kwambiri, zimapezeka kuti nano-carbonic acid yokonzedwa kuchokera ku calcium carbide slag Kashiamu imakumana ndi muyezo wadziko lonse ndipo imachepetsa kuipitsa komwe kumachitika chifukwa cha carbide slag.Njirayi ikupereka njira yabwino yopangira nano-calcium carbonate.

Zhu Min ndi ena adagwiritsa ntchito ammonium chloride pretreat calcium carbide slag, kenako adakonza nano-calcium carbonate ndi carbonization.Zotsatira zinawonetsa kuti pamene ammonium chloride solution inali 8%, kuchuluka kwa calcium carbide slag kunapitirira 92%.Lembani nano-calcium carbonate (avareji ya tinthu tating'onoting'ono ndi 38nm), chiyero ndi kuyera kwa chinthu chomwe chimapezedwa ndi njirayi ndikufika pa 99.65% ndi 98.60% motsatana, chomwe chimathetsa vuto la chiyero chochepa komanso kuyera koyipa komwe kumachitika chifukwa cha zonyansa ku nano- calcium carbonate, ndipo ndi njira yabwino yothetsera ntchito zamakampani zotsatila Njira yabwino yopangira njira imaperekedwa.

Mwachidule, kuchuluka kwa CO2 kumagwiritsidwa ntchito pokonzekera calcium carbonate slag, ndipo kugwiritsidwa ntchito kwamtengo wapatali kwa calcium carbide slag kumatha kuzindikirika nthawi imodzi.Komabe, n'zosavuta kupanga madzi oipa pamene pamwamba pasinthidwa ndi mankhwala owonjezera.Ngati sichimathandizidwa, chimayambitsa kuipitsa kwachiwiri.Zofunikira pakutsata Kuganiziranso mozama kumaperekedwa ku zotsatira za zomwe zidachitika pozindikira kukonzanso kwa carbide slag.
