I ka makahiki 2015, ua hōʻike ka mea hana ʻo Cui Weihua i kahi palapala hoʻopaʻa: kahi ʻano hana no ka hoʻomākaukau ʻana i ka calcium carbonate māmā kiʻekiʻe mai ka slag kila. Hiki ke hana i ka calcium carbonate kiʻekiʻe mai ka slag kila me ka hoʻohana ʻana i ʻōpala kila wili wili kū pololei?

Wahi a ka China Powder Technology Network, i hala koke aku nei, ua hoʻomaka ʻia ka "laina hōʻike ʻoihana hoʻohana piha ʻana o ke ʻano hao a me ke kila kila 100000 ton", kahi papahana i ʻaelike ʻia no ka "hoʻoulu hou ʻana iā Mongolia ma o ka ʻepekema a me ka ʻenehana", ma Baotou. Ua kūkulu pū ʻia ka papahana e Baotou Steel Group a me Yukuang Environmental Protection Technology (Shanghai) Co., Ltd. Ua hōʻike ʻia ua hoʻokumu ʻia ka papahana ma nā hopena o ka "laina hana hōʻoia 10,000 ton no ka hoʻohana piha ʻana i ka slag kila ma ke ʻano carbonization". Ua carbonized piha ʻia ka slag kila, a ma hope loa e hana i nā huahana ʻoihana e like me ka calcium carbonate kiʻekiʻe a me nā mea hao, i mea e hoʻomaopopo ai i ka hoʻohana hou ʻana i nā kumuwaiwai o ka slag kila. Ke hoʻohālikelike ʻia me ka ʻenehana kuʻuna, hiki i ka ʻenehana mālama ʻana i ka hao a me ke kila kila carbonization ke lawe pololei i ka carbon dioxide ma ke ʻano he mea maka e komo i ka hopena me ka hoʻemi ʻana i ka hoʻokuʻu ʻana o ke kalapona dioxide, nona ka hopena hoʻemi kalapona pālua, e hoʻokō ana i ka pahuhopu o ka hoʻemi ʻana i nā hoʻokuʻu kinoea ʻōmaʻomaʻo a me ka hoʻolaha ʻana i ka hoʻomohala ʻana o ka haʻahaʻa kalapona poepoe. Ma hope o ka pau ʻana o ka papahana, hiki ke mālama ʻia he 424000 tons o ka ʻōpala kila i kēlā me kēia makahiki, ʻoiai ma kahi o 100000 tons o ke kalapona ʻokikene hiki ke hoʻopaʻa ʻia (sila ʻia), a hiki ke hoʻokō ʻia ka hiki ke hana i 200000 tons o ka calcium carbonate maʻemaʻe kiʻekiʻe a me 310000 tons o nā mea hao. He ʻimi hōʻike ʻoihana hou kēia papahana, hiki ke hoʻolaha nui ʻia ma nā ʻoihana like. ʻOiai e hoʻokō ana i ke koi no ka hoʻohana piha ʻana i nā ʻōpala paʻa, he mea kūpono ia no ka hoʻokō ʻana i ka pahuhopu o ka piko kalapona a me ka hoʻopau ʻana i ke kalapona. ʻO ia hoʻi ka hiki ke hana ʻia o ka papahana o ka hana ʻana i ka calcium carbonate maʻemaʻe kiʻekiʻe mai ka ʻōpala kila. Hāʻawi pū ia i kahi ala hou no ka hoʻohana piha ʻana i nā ʻōpala paʻa ʻōpala kila.

ʻO nā hiʻohiʻona loea nui o ka hana ʻana i ka calcium carbonate maʻemaʻe kiʻekiʻe mai ka slag kila penei: ʻo ka mua, wili i ka slag kila i pauka, hōʻike i ka calcium oxide manuahi i loko o ka slag kila i ka ʻili o ka slag kila, unuhi i ka calcium oxide i loko o ka slag kila ma ke ʻano pulu me ka 0.5% acetic acid, kānana a hoʻomālamalama, a laila carbonize me ke kinoea carbon dioxide, a laila dehydrate, holoi, hoʻomaloʻo, hoʻomaʻalili, kuʻi a kānana iā ia e hana i ka calcium carbonate māmā maʻemaʻe kiʻekiʻe. Hoʻohana nui ʻia ka calcium carbonate māmā maʻemaʻe kiʻekiʻe ma ke ʻano he mea hoʻopiha no nā tile papahele artificial, rubber, plastics, hana pepa, uhi, pena, inika, kaula, lako hale, meaʻai, lāʻau lapaʻau, textiles, hānai, toothpaste a me nā huahana ʻē aʻe. I kēia kaʻina hana, pono e hōʻea ka wili maikaʻi o ka slag kila ma mua o 400 meshes. He aha ke ʻano o nā lako e hiki ke hoʻohana ʻia e hoʻokō i ka hana nui o ka pauka micro slag kila? Ma ke ʻano he mea hana ʻoihana okilawili wili slag, Paipai ʻo HCMilling (Guilin Hongcheng) iā ʻoe e kohoʻO ka ʻōpala kila HLMwili wili kū pololei no ka hana ʻana i ka pauka slag kila. I kēia manawa, ʻo ke kaʻina hana o ka pauka slag kila ma ka mākeke he wili mua + wili maikaʻi. Hiki ke wili ʻia ka slag kila a ʻoi aku ma mua o 420 microns ma hope o ka wili ʻana i ʻelua pae. ʻO ke kumukūʻai o nā lako, ka ʻāpana papahele a me ka hoʻohana ikehu awelika he mau hoʻopukapuka nui.

Ua hoʻokuʻu ka hui R&D a me nā loea o ka ʻoihana ʻo HCMilling (Guilin Hongcheng), ma o ka laulima hohonu a me ka hoʻāʻo ʻana, i kaʻO ka slag kila moʻo HLMwili wili kū pololei, hiki ke wili i ka pauka slag kila i ke ʻano i hoʻokahi manawa, e hoʻomaikaʻi nui ana i ka waiwai hoʻohana o ka pauka slag kila, a wehe i ka mākeke noi ma lalo. He lako hana pauka micro slag kila kūpono ia e mālama i ke kumukūʻai, ka hoʻohana ʻana i ka ikehu, ka ʻāpana papahele, ka hua a me ka waiwai i hoʻohui ʻia o nā huahana i hoʻopau ʻia.

Inā loaʻa iā ʻoe ke koi no ka hana ʻana a me ka hana ʻana o ka pauka slag kila, e ʻoluʻolu e kelepona mai iā mākou no nā kikoʻī a hāʻawi i ka ʻike e pili ana iā mākou:
