ʻO nā ʻōpala paʻa ʻoihana nui o Kina ka nui o nā huelo, ka lehu lele, ka lanahu gangue, ka hoʻoheheʻe ʻana, ka palahu a me ka gypsum desulfurization.ʻO ka hoʻomākaukau ʻana i nā mea kūkulu hale mai nā ʻōpala paʻa ua ʻoi aku ka nui o ka nānā ʻana.Ua hoʻomaikaʻi nā mea noiʻi i ka nui o ka hoʻohana ʻana i nā ʻōpala paʻa i ka ʻoihana hale ma o ka hoʻomaikaʻi ʻana a me ka noiʻi ʻana a me ka hoʻomohala ʻana i nā lako a me nā ʻenehana.I ka manawa like, ua hoʻopuka nā ʻāina like ʻole i nā kānāwai kākoʻo a me nā lula e hoʻoulu i ka hoihoi o nā ʻoihana no ka hoʻohana ʻana i nā ʻōpala paʻa, no laila e hoʻomaikaʻi ai i ka hopena o nā ʻōpala paʻa ʻoihana i ke kaiapuni.E like me ka mea hana o ka hao huelo wili wili, ko makouhao huelo wili wili ua hoʻohana nui ʻia i ka hao huelo one grinding building materials piha hoʻohana papahana.E hoʻolauna ʻo HCMilling(Guilin Hongcheng) i ka ʻenehana o ka hoʻomākaukau ʻana i nā mea kūkulu hale mai nā huelo hao.

1. Klinker sima calcined

He waiwai nui ka hao huelo i ka mea hao, hiki ke hoʻololi i ka pauka hao ma ke ʻano he mea maka no ka hana ʻana i ka clinker sima.ʻO ke kuni ʻana i ka ciment clinker me ka limestone, ke one quartz a me nā huelo hao e like me nā mea maka hiki ke hoʻemi pono i ka mahana calcination a me ke kumukūʻai o ka sima, akā ua kaupalena ka hui ʻana, a ʻo ka nui o ka hui ʻana e hoʻemi nui i ka ikaika sima.I kēia manawa, ʻo ka nui o nā huelo hao i hoʻohana ʻia no ka calcining clinker ciment he 15% wale nō.He mea koʻikoʻi ka hoʻomohala ʻana i nā mea hana 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. Hoʻohui paʻa

ʻO ka paʻakikī kiʻekiʻe o nā huelo hao mai ka māhele quartz kūloko, kahi kokoke i kahi one kahawai maoli a me ke one i hana ʻia, a hiki ke hoʻohui ʻia i loko o ke kaila e like me ka hui.Hiki ke hoʻomākaukau ʻia ke kaʻa me ka ikaika 28d ma kahi o 40MPa me ka hoʻohana ʻana i nā huelo hao me ka nui o ka nui ma lalo o 1mm e hoʻololi i ke one kahawai maoli ma ke ʻano he hui maikaʻi.Ma muli o ka optimization o ka aggregate grading, ʻo ka hoʻohana ʻana i nā huelo hao a me ke one i hana ʻia e ka mīkini e like me ka aggregate ʻaʻole hiki ke hoʻokō wale i nā koi o ke kaʻa no nā mea waiwai, akā ʻoi aku ka maikaʻi o ke kūpaʻa ma mua o ka hao a me ke one kahawai maoli, ʻoi aku ka maikaʻi. kūpono i ka hoʻomalu ʻana i ka maikaʻi o ka lāʻau.E pili ana i ke kaʻina hana pōmaikaʻi i kēia manawa, i mea e hoʻomaikaʻi ai i ka helu hoʻihoʻi metala, ʻoi aku ka maikaʻi o nā ʻāpana huelo hao, he paʻakikī ke hoʻokō i ka maʻamau o ka hōʻuluʻulu coarse a hoʻopili ʻia i ke kaila maʻamau.

3. Hoʻohui ʻia ka mineral concrete

Hoʻokumu nui ʻia nā mea hoʻohui mineral me nā siliceous amorphous, calcareous a me nā mea alumini, kahi mea nui i ka hoʻomaikaʻi ʻana i ka compactness, impermeability a me ka lōʻihi o ka koneki.Hiki iā lākou ke hōʻemi i ka hoʻohana ʻana i ka cement a hoʻemi i ka wela o ka hydration i ka manawa like.No laila, he mea nui e ʻimi i nā mea hoʻohui mineral hou no ka hoʻomohala mau ʻana o ka ʻoihana sima.ʻO ka quartz ka māhele mineral nui i nā huelo hao, he liʻiliʻi ka hana pozzolanic ma ke ʻano kūlohelohe.Pehea e hoʻomaikaʻi ai i ka "hana pozzolanic" o nā huelo hao i lilo i kumu nui o nā mea noiʻi o kēia manawa.Ma ke ʻano he mea maʻamau i hoʻohana ʻia no ka hoʻoulu ʻana i nā huelo hao, hiki i ka wili mīkini ke hōʻemi i ka ikehu hoʻāla o nā huelo hao a hoʻohua i nā hemahema lattice a me ka deformation plastic.Hōʻike ka noiʻi hiki i ka wili mīkini ke hoʻoulu i ka hana pozzolanic o nā ʻāpana mineral maʻamau i nā huelo hao.Ke emi nei ka nui o nā minela lepo mechanically, hiki i ka quartz ke hana me Ca (OH) 2 i loko o ka sima slurry e hoʻohua i ka amorphous hydrated calcium silicate gel a me ka ettringite crystal a me nā huahana hydration ʻē aʻe.Hōʻike ka noiʻi inā ʻoi aku ka nui o ka mīkini wili ma mua o 40min, ʻike ʻia ka emi ʻana o ke kihi ʻoi o nā huelo hao, hōʻike ʻia nā mea liʻiliʻi liʻiliʻi, a hoʻomaikaʻi maikaʻi ʻia ke ʻano like.I loko o ka ʻōnaehana calcium oxide anhydrite hao, hiki ke hoʻohui ʻia ka siliceous iron tailing o ka mīkini wili ʻana me 30% e hoʻomākaukau ai i 32.5 sima.Ma lalo o ke kūlana o ka haʻahaʻa wai binder ratio, ʻoi aku ka maikaʻi o ka pauka huelo hao hiki ke hoʻoikaika nui i ka hydration mua o ka paʻi sima composite, e hoʻonui i ka hoʻolālā pore o ka mortar, a hoʻomaikaʻi i ka ikaika mua.ʻO ka hoʻonui ʻia ʻana o ka ʻāpana ili kūikawā o nā huelo hao ʻaʻohe hopena maopopo i ka hoʻomaikaʻi ʻana i kāna papa kuhikuhi hana;Hiki i ka hoʻololi ʻana o ka mahana hoʻōla ke hoʻonui nui i ka papa kuhikuhi hana ma ka pae mua (7d), akā he liʻiliʻi ka hopena i ka papa kuhikuhi hana ma ka pae hope (28d).No ka ʻōnaehana hoʻohui iron tailings slag, hiki ke hoʻomaikaʻi ʻia ka papa kuhikuhi hana ma o ka hoʻomaikaʻi ʻana i ka mīkini wili, pēlā e hoʻomaikaʻi ai i ka lōʻihi o ka ʻuala.Hiki i ka hoʻohana kūpono ʻana o ka mea hoʻohaʻahaʻa wai ke hoʻonui i ka ʻike o nā huelo hao i loko o ka pahu maʻamau mai 30% a 40%.Hiki i ka wili hao hao ke hoʻomaikaʻi i ka maikaʻi o ka wili ʻana ma o kona hopena ponoʻī, pēlā e hoʻoulu ai i ka hana pozzolanic o nā huelo hao.Ma ka hoʻonui ʻana i ka lakio o nā huelo hao, slag, clinker a me gypsum composite cementitious material, ultra-high performance concrete with performance meeting the national standard.
