ʻO nā ʻōpala paʻa ʻoihana nui o Kina he mau tailings, fly ash, lanahu gangue, slag smelting, lanahu-fire slag a me ka desulfurization gypsum. Ua huki nui ʻia ka nānā ʻana o ka hoʻomākaukau ʻana i nā mea kūkulu hale mai nā ʻōpala paʻa. Ua hoʻomaikaʻi nā mea noiʻi i ka nui o ka hoʻohana ʻana i nā ʻōpala paʻa i ka ʻoihana mea kūkulu hale ma o ka hoʻomaikaʻi ʻana a me ka noiʻi a me ka hoʻomohala ʻana i nā lako a me ka ʻenehana. I ka manawa like, ua hoʻopuka nā ʻāina like ʻole i nā kānāwai a me nā lula e hoʻoulu ai i ka hoihoi o nā ʻoihana no ka hoʻohana ʻana i nā ʻōpala paʻa, no laila e hoʻomaikaʻi ana i ka hopena o nā ʻōpala paʻa ʻoihana i ke kaiapuni i kekahi ʻano. Ma ke ʻano he mea hana o ka wili hao tailings, ʻo kā mākouwili wili kū pololei no ka hao ua hoʻohana nui ʻia i loko o ka papahana hoʻohana piha ʻana o ka wili ʻana i nā mea kūkulu hale me ka hao tailings. E hoʻolauna ʻo HCMilling (Guilin Hongcheng) i ka ʻenehana o ka hoʻomākaukau ʻana i nā mea kūkulu hale mai nā tailings hao.

1. ʻO ka clinker sima i hoʻopaʻa ʻia

Waiwai ka huelo hao i ka mea hao, hiki ke pani i ka pauka hao ma ke ʻano he mea maka no ka hana ʻana i ka clinker sima. ʻO ka puhi ʻana i ka clinker sima me ka pōhaku lepo, ke one quartz a me nā huelo hao ma ke ʻano he mea maka hiki ke hōʻemi pono i ka mahana calcination a me ke kumukūʻai o ka sima, akā ua kaupalena ʻia ka nui o ke kāwili ʻana, a ʻo ka nui o ke kāwili ʻana e hōʻemi nui i ka ikaika o ka sima. I kēia manawa, ʻo ka nui o nā huelo hao i hoʻohana ʻia no ka calcining ʻana i ka clinker sima he 15% wale nō. He mea wikiwiki ia e hoʻomohala i nā lako hou a me nā ʻenehana hou e hoʻomaikaʻi i ka nui o nā huelo hao a hōʻoia i ka maikaʻi o nā huahana sima.

2. ʻO ka ʻākoakoa sima

ʻO ke kiʻekiʻe o ka paʻakikī o nā ʻōpala hao e hele mai ana mai ka pae quartz kūloko, nona ka nui o ka ʻāpana e kokoke ana i kekahi one muliwai maoli a me ke one i hana ʻia, a hiki ke hoʻohui ʻia i loko o ka sima ma ke ʻano he aggregate. Hiki ke hoʻomākaukau ʻia ka sima me ka ikaika 28d ma kahi o 40MPa ma ka hoʻohana ʻana i nā ʻōpala hao me ka nui o ka ʻāpana ma lalo o 1mm e pani i ke one muliwai maoli ma ke ʻano he aggregate maikaʻi. Ma muli o ka hoʻonui ʻana i ka grading aggregate, ʻo ka hoʻohana hui ʻana o nā ʻōpala hao a me ke one i hana ʻia e ka mīkini ma ke ʻano he aggregate ʻaʻole hiki ke hoʻokō wale i nā koi o ka sima no nā mea, akā he kūpaʻa maikaʻi hoʻi ma mua o nā ʻōpala hao a me ke one muliwai maoli, ʻoi aku ka maikaʻi o ka kaohi ʻana i ka maikaʻi o ka sima. No ke kaʻina hana hoʻomaikaʻi o kēia manawa, i mea e hoʻomaikaʻi ai i ka wikiwiki o ka hoʻōla ʻana o ka metala, ke ʻoi aku ka maikaʻi o nā ʻāpana ʻōpala hao, he mea paʻakikī ke hoʻokō i ke kūlana o ka aggregate coarse a hoʻopili i ka sima maʻamau.

3. Hoʻohuihui mineral sima

ʻO nā mea hoʻohui mineral i hana nui ʻia me nā mea siliceous amorphous, calcareous a me alumini, nona kahi kuleana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka compactness, impermeability a me ke kūpaʻa o ka sima. Hiki iā lākou ke hōʻemi i ka hoʻohana ʻana i ka sima a hōʻemi i ka wela o ka hydration i ka manawa like. No laila, he mea nui e loaʻa nā mea hoʻohui mineral hou no ka hoʻomohala mau ʻana o ka ʻoihana sima. ʻO ka pae mineral nui i loko o nā tailings hao he quartz maʻamau, nona ka hana pozzolanic liʻiliʻi i ke kūlana kūlohelohe. Pehea e hoʻomaikaʻi ai i ka "hana pozzolanic" o nā tailings hao ua lilo i kumuhana nui o nā mea noiʻi o kēia manawa. Ma ke ʻano he hoʻokahi o nā ʻano hana i hoʻohana pinepine ʻia no ka hoʻoulu ʻana i nā tailings hao, hiki i ka wili mechanical ke hōʻemi i ka ikehu hoʻāla o nā tailings hao a hana i nā hemahema lattice a me ka deformation plastic. Hōʻike ka noiʻi hiki i ka wili mechanical ke hoʻoulu i ka hana pozzolanic o nā pae mineral maʻamau i loko o nā tailings hao. I ka emi ʻana o ka nui o nā ʻāpana o nā mineral i wili ʻia e ka mīkini, hiki i ka quartz ke hana me Ca (OH) 2 i loko o ka slurry sima e hana i ka amorphous hydrated calcium silicate gel a me ka ettringite crystal a me nā huahana hydration ʻē aʻe. Ua hōʻike ʻia ka noiʻi ʻana i ka wā e ʻoi aku ai ka wili ʻana o ka mīkini ma mua o 40 mau minuke, ua emi maopopo ka kihi ʻoi o nā ʻōpala hao, ʻoi aku ka nui o nā ʻāpana liʻiliʻi e hōʻike ʻia, a ua hoʻomaikaʻi mālie ʻia ke ʻano like. I loko o ka ʻōnaehana calcium oxide ʻōpala hao anhydrite, hiki ke hoʻohui ʻia ka ʻōpala hao siliceous o ka wili ʻana o ka mīkini me 30% e hoʻomākaukau i ka sima 32.5. Ma lalo o ke kūlana o ka lakio hoʻopaʻa wai haʻahaʻa, hiki i ka pauka ʻōpala hao maikaʻi ke hoʻoulu nui i ka hydration mua o ka paʻi sima composite, e hoʻonui i ka ʻano pore o ka mortar, a hoʻomaikaʻi i ka ikaika mua. ʻAʻohe hopena maopopo o ka hoʻonui ʻana o ka ʻili kikoʻī o nā ʻōpala hao i ka hoʻomaikaʻi ʻana i kāna helu hana; Hiki i ka loli o ka mahana hoʻōla ke hoʻonui nui i ka helu hana i ka wā mua (7d), akā he liʻiliʻi ka hopena i ka helu hana i ka wā hope (28d). No ka ʻōnaehana hui slag ʻōpala hao, hiki ke hoʻomaikaʻi ʻia ka helu hana ma ka hoʻomaikaʻi ʻana i ke ʻano wili, no laila e hoʻomaikaʻi ana i ke kūpaʻa o ka sima. ʻO ka hoʻohana kūpono ʻana i ka mea hoʻemi wai hiki ke hoʻonui i ka ʻike o nā ʻōpala hao i loko o ka sima maʻamau mai 30% a 40%. Hiki i ka wili ʻana o nā ʻōpala hao ke hoʻomaikaʻi i ka pono o ka wili ʻana ma o kona hopena ponoʻī, a pēlā e hoʻoulu ai i ka hana pozzolanic o nā ʻōpala hao. Ma ka hoʻonui ʻana i ka lakio o nā ʻōpala hao, slag, clinker a me nā mea sima gypsum composite, hiki ke hoʻomākaukau ʻia ka sima hana kiʻekiʻe loa me ka hana e kū ana i ke kūlana aupuni.
