Pehea e hiki ai i ka poʻe hana mīkini hana ʻili kila ke hoʻololi i ka ʻōpala hao i waiwai?
I ke kūlana o kēia manawa o ka overcapacity o ka hana kila ma koʻu ʻāina, ʻo ka slag kila i hana ʻia ʻo ia ka pest mua e hoʻohaumia i ke kaiapuni. ʻO ka ʻōpala hao ka ʻōpala nui o ka hana metala ʻoihana a me kekahi o nā ʻōpala paʻa ʻoihana. Wahi a nā ʻikepili ʻikepili kūpono, ʻo ka hoʻokuʻu ʻana o ke kila kila honua ma 2013 ma kahi o 200 miliona tons. I kēia mau makahiki i hala iho nei, ua ulu wikiwiki ka ʻoihana o koʻu ʻāina, a ua hoʻonui pū ʻia ka hoʻopuka ʻana o ka slag kila. No laila, ʻo ka hoʻohana ʻana a me ka mālama ʻana i ka palaka kila, ua lilo pū kekahi o nā mea i nānā nui ʻia e nā keʻena aupuni o koʻu ʻāina.
1. Hiki ke hoʻohana ʻia ka mea hao kila e like me nā mea hao
He nui ka hao i loko o ke kila ʻōpala a me ke kila kila, me ka hapa awelika o ka nui ma kahi o 25%, a he 10% ka nui o ka hao hao. Ma hope o ka hoʻokaʻawale ʻana i ka magnetic, hoʻohana ʻia ka hapa nui o ka slag kila me nā mea hao kiʻekiʻe e like me nā mea maka no ka hana kila a me ka hao.
2. Hiki ke hoʻohana i ka hana mahiʻai
Hoʻohana ʻia e like me ke kila slag phosphate fertilizer, loaʻa i ka slag kila ka nui o ka zinc, manganese, hao, keleawe a me nā mea ʻē aʻe, a he ʻokoʻa hoʻi ka hopena o ka fertilizer ma nā ʻāina like ʻole a me nā mea kanu i nele i kēia mau ʻano.
3. Hiki ke hoʻohanaʻia i ka hanaʻana i nā mea hale
No ka mea, loaʻa i ka slag kila nā minelala ikaika e like me ka sima a loaʻa iā ia nā waiwai cementitious hydraulic, hiki ke hoʻohana ʻia ka pala kila ma ke ʻano he kumu kumu a hui pū ʻia no ka sima. I ka manawa like, ʻo ka pōhaku i hoʻopaʻa ʻia ke kila kila i nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe, ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi, ke kūpaʻa maikaʻi a me ka lōʻihi, no laila ua hoʻohana nui ʻia i nā ala kaʻa, nā alaloa a me ka ʻenehana backfill.
ʻO ka mīkini hana pōhaku ʻakomi pihahiki ke hana i nā pōhaku lepo. Loaʻa i ka palapa kila ponoʻī ka calcium a me ka magnesium manuahi. Ma hope o ka ʻoki ʻia ʻana o ka calcium a me ka magnesium manuahi a waiho ʻia e kū, hiki ke hoʻemi ʻia ka calcium manuahi a me ka magnesium i ka hana no ka hana ʻana i nā pōhaku kiʻekiʻe kiʻekiʻe i puhi ʻole ʻia, nā pōhaku lepo, nā curbstones, nā pōhaku permeable, nā pōhaku hydraulic a me nā huahana cement o nā kikoʻī like ʻole.
He paʻakikī ke kila kila a hiki ke ʻoki ʻia i loko o nā ʻāpana o 0 ~ 8mm e hana i nā pōhaku lepo ʻole. He kiʻekiʻe loa ka nalowale ʻana o nā mīkini palaki i ka wā o ke kaʻina hana, no laila pono e koho ʻia nā ʻāpana mīkini kiʻekiʻe. Pono ka mea hana laina hana brick piha pono e hoʻomaʻamaʻa i ka wela, CNC kiʻekiʻe kiʻekiʻe o ka hana ʻana, ke ʻoki uea, ka nitriding, ka hana kanaka hoʻokahi a me nā kaʻina hana ʻē aʻe e kū i ka lole kiʻekiʻe o ka slag kila.
I kēia manawa, hoʻohana nui nā mea hoʻohana i ka mea hana mīkini hana kila kila Quangong e hana i nā pōhaku lepo, a he ʻoihana hoʻomaʻamaʻa benchmark i kēia kahua. I mea e hoʻohana maikaʻi ai i ka hoʻohana ʻana i ka ʻōpala kila, ua hoʻolaʻa nā poʻe loea ʻo Quangong iā lākou iho i ka noiʻi, hoʻopau hohonu i ka haku ʻana o ke kila kila i loko o ke keʻena loiloi mea, a hana i kahi hōʻike hiki ke ʻoki a hōʻemi i ka calcium manuahi a me ka magnesium i loko. kila kila a hoʻomohala i kahi mīkini hana kila kila no ka hana ʻana i nā pōhaku kila. Hoʻohana pono nā mea mīkini pōhaku lepo i ka ʻōpala kila ma ke ʻano he aggregate e ale ai, a hana i nā huahana kila kila me nā hopena hoʻomalu kaiaola a me ke kaiapuni ma o ka haʻalulu ʻana a me ke kaomi ʻana i ka mīkini pōhaku lepo ʻole. Hoʻohana ka slag kila i nā lako hana hana brick piha piha i kahi hoʻolālā automated e hoʻohui i nā hydraulics, nā mīkini a me ka uila i ka wā o ka noiʻi a me ka hoʻomohala ʻana. He hiʻohiʻona nani, hana maʻalahi, palekana kiʻekiʻe a me ka helu haʻahaʻa haʻahaʻa.
