E noiʻi e pili ana i ke kumu hana o ka pauka lepo a me ka polycarboxylic acid wai-reducing agent:
Manaʻo ʻia ʻo ke kumu nui o ka hoʻopili ʻana o ka pauka lepo i ke koki i hui pū ʻia me ka lignosulfonate a me ka naphthalene-based water reducing agents, ʻo ia ka hoʻokūkū adsorption ma waena o ka lepo lepo a me ka sima. ʻAʻohe wehewehe like ʻole e pili ana i ke kumu hana o ka pauka lepo a me ka polycarboxylic acid wai-reducing agent.
Manaʻo kekahi poʻe naʻauao he ʻano like ke kumu hana o ka pauka lepo a me ka mea hoʻemi wai me ka sima. Hoʻopili ʻia ka mea hoʻohaʻahaʻa wai ma ka ʻili o ka sima a i ʻole ka lepo lepo me nā hui anionic. ʻO ka ʻokoʻa, ʻoi aku ka nui a me ka wikiwiki o ka adsorption o ka mea hoʻemi wai e ka pauka lepo ma mua o ka sima. I ka manawa like, ʻoi aku ka nui o ka wai a me ka hoʻohaʻahaʻa ʻana i ka wai manuahi i loko o ka slurry, e pili pono ana i ka hana ʻana o ka ʻuala.
Nā hopena o nā minela like ʻole i ka hana o nā mea hoʻemi wai:
Hōʻike nā noiʻi ʻo ka lepo pālolo wale nō me ka hoʻonui nui a me nā waiwai absorption wai e loaʻa i kahi hopena koʻikoʻi i ka hana hana a me nā waiwai mechanical ma hope o ke kaʻa.
ʻO ka lepo lepo maʻamau i loko o nā ʻāpana he kaolin, illite a me montmorillonite. ʻO keʻano likeʻole o ka mea hoʻohaʻahaʻa wai he mauʻano likeʻole ia i nā lepo lepo me nā hui mineral likeʻole, a he mea koʻikoʻi kēiaʻokoʻa no ke kohoʻana i nā mea hoʻohaʻahaʻa wai a me ka hoʻomohalaʻana i nā mea hoʻohaʻahaʻa wai a me nā mea pale.
Ka hopena o ka lepo lepo ma luna o nā waiwai paʻa:
ʻAʻole pili wale ka hana ʻana o ka koneki i ka hoʻokumu ʻana i ka koneki, akā pili pū kekahi i nā ʻano mechanical hope a me ka lōʻihi o ka lāʻau. ʻAʻole paʻa ka nui o nā ʻāpana lepo lepo, emi i ka wā maloʻo a hoʻonui i ka wā pulu. I ka hoʻonui ʻana o ka lepo, inā he polycarboxylate wai-reducing agent a i ʻole naphthalene-based water-reducing agent, e hōʻemi ia i ka nui o ka hoʻohaʻahaʻa wai, ka ikaika, a me ka hāʻule ʻana o ka lepo. ʻO ka hāʻule, a me nā mea ʻē aʻe, lawe mai i ka pōʻino nui i ke kaʻa.
Ka manawa hoʻouna: Mar-05-2024
