Calcium carbide slag bụ ihe mkpofu nke mejupụtara calcium hydroxide mgbe hydrolysis nke calcium carbide ga-enweta gas acetylene. Nkwadebe nke ngwaahịa kemịkal sitere na carbide slag bụ maka ebumnuche nke imegharị ihe onwunwe, na mmepe nke usoro akwụkwọ ndụ akwụkwọ ndụ na mbelata ụgwọ teknụzụ ga-abụ ihe nyocha nke ga-eme n'ọdịnihu.

A na-eji Nano-calcium carbonate eme ihe n'ọtụtụ ebe na rọba, rọba, imepụta akwụkwọ, ink na ubi ndị ọzọ, nwere nnukwu ahịa ahịa. N'ime ụlọ ọrụ, a na-ejikarị usoro carbonization na-emepụta nano-calcium carbonate, CaO na-enweta site na calcining limestone, nke a na-agbaze ma kwụsịtụ Ca (OH) 2 Crush, tinye onye na-ahụ maka njikwa ụdị crystal, gafere CO2 carbonization, akpịrị ịkpọ nkụ, na ọgwụgwọ elu iji nweta nano-calcium carbonate. N'oge usoro a, a ga-emepụta gas na-ekpofu (CO2), mmiri na-adịghị ọcha (mmiri ọcha) na ihe mkpofu, nke ga-emecha mee ka mbelata nke ngwaahịa ngwaahịa ma belata ma ọ bụ ghọta ihe atọ na-efu efu efu efu na imeziwanye àgwà nke nano-calcium carbonate bụ isi okwu, na carbide slag bụ kpamkpam kwekọrọ na echiche nchebe gburugburu ebe obibi nke ịgwọ ihe mkpofu na ihe mkpofu.

Ka ọ dị ugbu a, nkwadebe nke nano-calcium carbonate sitere na calcium carbide slag gụnyere ụzọ atọ: calcination slaking, hydrochloric acid leaching na ammonium chloride leaching. Li Rui et al. jiri usoro nhazi nke calcination na nrụgide nrụgide na-eme ka calcium carbide slag meghachi omume na CO2 flue gas n'ime ikuku carbonization nke nrụgide iji nweta nano calcium carbonate spherical (60nm). Usoro a abụghị naanị na-edozi mmetọ nke ikuku gas na-ekpofu CO2, ma na-enwetakwa ngwaahịa bara uru dị elu; Liu Fei et al. nakweere usoro leaching hydrochloric acid, acidified calcium carbide slag na hydrochloric acid nwere pH=8, ma mee mmeghachi omume metathesis na sodium carbonate. Nsonaazụ gosiri na acidified calcium carbide slag ga-akwalite calcium carbonate whiskers The omume nke agglomeration na keadighi rarii alaka forked na-emecha na-eduga na aragonic calcium carbonate whiskers na otu nkesa na elu akụkụ ruru (30-60).

Usoro a na-atụ aro ụzọ usoro dị irè maka nkwadebe nke nano-calcium carbonate.

Zhu Min na ndị ọzọ jiri ammonium chloride pretreat calcium carbide slag, wee kwadebe nano-calcium carbonate site carbonization. Nsonaazụ gosiri na mgbe ntinye nke ammonium chloride ngwọta bụ 8%, ọnụ ọgụgụ ojiji nke calcium carbide slag karịrị 92%. Ụdị nano-calcium carbonate (nkezi urughuru nha bụ 38nm), ịdị ọcha na ịdị ọcha nke ngwaahịa a nwetara site na usoro a ruo 99.65% na 98.60% n'otu n'otu, nke na-edozi nsogbu nke ịdị ọcha dị ala na ọcha na-adịghị mma kpatara site na adịghị ọcha na nano-calcium carbonate, na bụ ezigbo ngwọta maka ezigbo usoro ụlọ ọrụ na-esote.
