ʻO ka mea hoʻohaʻahaʻa wai he mea hoʻohui paʻa e hiki ke hōʻemi i ka nui o ka hui ʻana i ka wai me ka mālama ʻana i ka hāʻule ʻana o ke kō. ʻO ka hapa nui o lākou he surfactants anionic. Ma hope o ka hoʻohui ʻia ʻana i ka hui ʻana, he hopena dispersing 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.
E like me ka helehelena:
Hoʻokaʻawale ʻia i ka wai a me ka pauka. He 10%, 20%, 40% ka maʻiʻo paʻa o ka wai, 50%, a ʻo 98% ka paʻa o ka pauka.
E like me ka hiki ke hōʻemi i ka wai a hoʻonui i ka ikaika:
Hoʻokaʻawale ʻia ia i ka mea hoʻemi wai maʻamau (ʻike ʻia ʻo plasticizer, me ka nui o ka emi ʻana o ka wai ma lalo o 8%, i hōʻike ʻia e ka lignin sulfonates), ka mea hoʻemi wai kiʻekiʻe (ʻike ʻia ʻo superplasticizer, me ka nui o ka emi ʻana o ka wai. ma mua o 14%, me ka naphthalene series, melamine series, aminosulfonate series, aliphatic series, etc.) ʻano ikaika mua, ʻano maʻamau a me ke ʻano hoʻonohonoho lohi.
E like me nā mea haku mele:
Lignin sulfonates, polycyclic aromatic salts, wai-soluble resin sulfonates, naphthalene-based high-efficiency water reducers, aliphatic high-efficiency water reducers, amino high-efficiency water reducers, polycarboxylate high-performance water reducers, etc.
E like me ka hui kemika:
Lignin sulfonate hoemi wai, naphthalene-ma muli o ka wai ho'ēmi wai kiʻekiʻe, melamine-ka mea ho'ēmi wai kiʻekiʻe-efficiency, aminosulfonate-ma muli o ka wai hoemi wai kiʻekiʻe, fatty acid-wai hoemi wai kiʻekiʻe, polycarboxylate. .
ʻO ke kuleana o ka mea hoʻemi wai:
1. Me ka hoʻololiʻoleʻana i ka lakio o nā mea maka (koe wale ka cement) a me ka ikaika o ka pahu, hiki ke hoʻemiʻia ka nui o ka sima.
2. Me ka hoʻololiʻole i ka lakio o nā mea maka (koe ka wai) a me ka hāʻuleʻana o ka pahu, hiki ke hoʻemi i ka nui o ka wai e hoʻonui i ka ikaika o ka'ōpala.
3. Me ka hoʻololi ʻole ʻana i ka ratio o nā mea maka, hiki ke hoʻomaikaʻi maikaʻi ʻia ka rheology a me ka plasticity o ke koʻikoʻi, i hiki ke hoʻokō ʻia ke kūkulu ʻana i ka umekaumaha, pumping, me ka haʻalulu ʻole, etc. .
4.ʻO ka hoʻohuiʻana i ka mea hoʻohaʻahaʻa wai kiʻekiʻe i ka paʻakai hiki ke hoʻonui i ke ola o ka pahu ma mua o ka pālua,ʻo ia hoʻi, e hoʻonui i ke ola lawelawe maʻamau o ka hale ma mua o ka pālua.
5. E ho'ēmi i ka hoʻohaʻahaʻa o ka paʻa paʻa a pale i nā māwae i loko o nā mea hana; hoʻomaikaʻi i ka hau kūʻē, kahi kūpono i ke kūkulu hoʻoilo.
Mechanism o ka hana o ka wai reducer:
· Hoʻopuehu
· Lubrication
· Keʻakeʻa kūʻokoʻa
· Hoʻokuʻu lohi ka hopena o nā kaulahao ʻaoʻao copolymer i grafted
