Me ka hoʻomohala ʻana i ka ʻenehana a me ka hoʻokele waiwai, a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ʻenekinia, ʻoi aku ka nui o ka hana o ka mea hoʻemi wai i ka ʻeke.I kēia lā, e lawe au iā ʻoe e hoʻomaopopo i ke kuleana koʻikoʻi o ka mea hoʻohaʻahaʻa wai i ka ʻoihana kūkulu.
Hoʻokaʻawale ʻia ka hui hoʻohaʻahaʻa wai kiʻekiʻe i: (1)nā lignossulfonates;(2) nā paʻakai ʻala polycyclic;(3) wai-soluble resin sulfonates.Naphthalene superplasticizer, aliphatic superplasticizer, amino superplasticizer, polycarboxylicʻakika superplasticizer, etc.
Hoʻokaʻawale ʻia ke ʻano hiʻohiʻona i ka wai a me ka pauka.ʻO ka maʻiʻo paʻa o ka wai maʻamau he 20%, 40% (kapa ʻia ʻo ka waiʻona makuahine), 60%, a ʻo ka maʻi paʻa o ka pauka ma ke ʻano he 98%.E like me ka wai ho'ēmi a hoʻonui i hiki omea hoemi wai, Ua mahele ia i ka wai hoemi wai maʻamau (ʻike pū ʻia ʻo plasticizer, ʻaʻole emi ka nui o ka wai ma lalo o 8%, i hōʻike ʻia e lignosulfonate), superplasticizer (ʻike pū ʻia ʻo superplasticizer) Plasticizer, ʻaʻole emi ka nui o ka wai ma lalo o 14%, me ka naphthalene, melamine, sulfamate, aliphatic, a me nā mea'ē aʻe) a me nā mea hoʻohaʻahaʻa wai kiʻekiʻe (ʻaʻole i emi iho ka nui o ka wai ma lalo o 25%, me ka polycarboxylic acid Ua hōʻikeʻia e ka wai ho'ēmi wai), a ua māheleʻia i ka ikaika mua. ʻano, ʻano maʻamau a me ka retarder.
Ma hope o ka hoʻohui ʻana i ka hui ʻana, hiki iā ia ke hoʻopuehu i nā ʻāpana sima, hiki ke hoʻomaikaʻi i kāna hana, hoʻemi i ka hoʻohana ʻana i ka wai, a hoʻomaikaʻi i ka wai o ka hui ʻana;a i ʻole e hoʻemi i ka hoʻohana ʻana i ka sima a mālama i ka sima.
ʻO kā mākou hui he mea hana ʻoihana o nā mea hoʻohaʻahaʻa wai, me ʻelua mau mea kanu hana ʻoihana, ʻeono mau laina hana ʻoihana nui, ʻoihana hana R&D hui, kākoʻo i ka hana pilikino a me ka lawelawe hāpana manuahi, kūikawā i nā admixtures concrete e hōʻoluʻolu ai nā mea kūʻai aku.
