ʻO ka ʻōpala calcium carbide ka ʻōpala i haku nui ʻia me ka calcium hydroxide ma hope o ka hydrolysis o ka calcium carbide e loaʻa ai ke kinoea acetylene. ʻO ka hoʻomākaukau ʻana i nā huahana kemika mai ka ʻōpala carbide no ke kumu o ka hana hou ʻana i nā kumuwaiwai, a ʻo ka hoʻomohala ʻana i nā kaʻina hana ʻōmaʻomaʻo a me ka hōʻemi ʻana i nā kumukūʻai ʻenehana ke kikowaena o ka noiʻi e hiki mai ana. ʻO HCMilling (Guilin Hongcheng) kahi mea hana oka calcium hydroxidehoʻopau ʻanaa mekalipunawili wili kalaponanā lako. E hoʻolauna kēia iā ʻoe i ke kaʻina hana o ka hoʻomākaukau ʻana i ka nano calcium carbonate mai ka carbide slag.

Hoʻohana nui ʻia ka Nano-calcium carbonate i ka rubber, plastics, pepa hana, ʻīnika a me nā ʻoihana ʻē aʻe, me ka hiki ke kūʻai nui ʻia. I ka ʻoihana, hoʻohana nui ʻia ke ʻano carbonization e hana i ka nano-calcium carbonate, a loaʻa ka CaO ma o ka calcining limestone, kahi i hoʻoheheʻe ʻia a hoʻokuʻu ʻia ʻo Ca(OH)2 Crush, hoʻohui i ka mea hoʻomalu ʻano kristal, hala i ka carbonization CO2, dehydration, a me ka mālama ʻana i ka ʻili e loaʻa ai ka nano-calcium carbonate. I loko o kēia kaʻina hana, e hana ʻia ke kinoea ʻōpala (CO2), ka wai ʻōpala (wai keʻokeʻo) a me nā koena ʻōpala, kahi e alakaʻi ai i ka emi ʻana o ka maikaʻi o ka huahana a hōʻemi a hoʻomaopopo paha i nā ʻōpala ʻekolu ʻO ka hoʻokuʻu ʻole a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka nano-calcium carbonate nā pilikia nui, a ʻo ka carbide slag e kūlike loa me ka manaʻo palekana kaiapuni o ka mālama ʻana i ka ʻōpala me ka ʻōpala.

I kēia manawa, ʻo ka hoʻomākaukau ʻana o ka nano-calcium carbonate mai ka calcium carbide slag nui e komo pū ana me ʻekolu mau ʻano: calcination slaking, hydrochloric acid leaching a me ammonium chloride leaching. Ua hoʻohana ʻo Li Rui et al. i ke ala hana o ka calcination a me ka pressure slaking e hana i ka calcium carbide slag e hana me ke kinoea flue CO2 i loko o kahi reactor carbonization pressurized e loaʻa ai ka spherical nano calcium carbonate (60nm). ʻAʻole wale kēia kaʻina hana e hoʻoponopono i ka haumia o ke kinoea ʻōpala CO2, akā loaʻa pū kekahi i nā huahana waiwai nui; Ua lawe ʻo Liu Fei et al. i ke kaʻina hana hydrochloric acid leaching, acidified calcium carbide slag me ka hydrochloric acid me ka pH = 8, a ua hoʻokō i ka metathesis reaction me ka sodium carbonate. Ua hōʻike nā hopena e hoʻolaha ka acidified calcium carbide slag i nā whiskers calcium carbonate. ʻO ka hanana ʻana o ka agglomeration a me nā lālā ʻokiʻoki coarse e alakaʻi hope loa i nā whiskers calcium carbonate aragonitic me ka hoʻolaha like a me ka ratio hiʻohiʻona kiʻekiʻe (30-60). Ke hoʻohālikelike ʻia me nā mea maka maʻemaʻe kiʻekiʻe, ua ʻike ʻia ua kūlike ka waikawa nano-carbonic i hoʻomākaukau ʻia mai ka calcium carbide slag me ke kūlana aupuni a hōʻoluʻolu i ka haumia i hoʻokumu ʻia e ka carbide slag. Hāʻawi kēia kaʻina hana i kahi ala hana kūpono no ka hoʻomākaukau ʻana o ka nano-calcium carbonate.

Ua hoʻohana ʻo Zhu Min a me nā poʻe ʻē aʻe i ka ammonium chloride e hoʻomaʻamaʻa mua i ka calcium carbide slag, a laila hoʻomākaukau i ka nano-calcium carbonate ma o ka carbonization. Ua hōʻike ʻia nā hopena i ka wā i 8% ka nui o ka hopena ammonium chloride, ʻoi aku ka nui o ka hoʻohana ʻana o ka calcium carbide slag ma mua o 92%. ʻO ke ʻano nano-calcium carbonate (ʻo ka nui o ka ʻāpana awelika he 38nm), ʻo ka maʻemaʻe a me ke keʻokeʻo o ka huahana i loaʻa e kēia kaʻina hana a hiki i ka 99.65% a me 98.60%, kahi e hoʻoponopono ai i ka pilikia o ka maʻemaʻe haʻahaʻa a me ke keʻokeʻo haʻahaʻa i hoʻokumu ʻia e nā haumia i ka nano-calcium carbonate, a he hopena maikaʻi ia no nā noi ʻoihana ma hope. Hāʻawi ʻia kahi ala hana maikaʻi.

I ka hōʻuluʻulu manaʻo, hoʻohana ʻia ka nui o CO2 i ka hoʻomākaukau ʻana i ka ʻōpala calcium carbonate, a hiki ke hoʻohana ʻia ka waiwai nui o ka ʻōpala calcium carbide i ka manawa like. Eia nō naʻe, maʻalahi ka hana ʻana i ka wai hoʻoneoneo ke hoʻololi ʻia ka ʻili e nā mea hoʻohui kemika. Inā ʻaʻole i mālama ʻia, e hana ia i ka haumia lua. Nā pono hahai E hāʻawi hou ʻia ka noʻonoʻo piha ʻana i nā huahana o ka hopena e hoʻokō ai i ka hana hou ʻana o ka ʻōpala carbide.
