Lilo ka Naphthalene Superplasticizer i mea pauka ma o ka sulfonation, hydrolysis, condensation, neutralization, filtration, a me ka maloʻo ʻana. ʻO ke kaʻina hana o ka naphthalene-based high-efficiency water reducer ua makua, a paʻa ka hana huahana. Ma ka lima hoʻokahi, hiki ke hoʻohana pololei ʻia kēia huahana i ka koneki, a ua haku ʻia ka hana o ka wai hoʻohaʻahaʻa wai e nā mea ʻenehana. Hiki nō hoʻi ke wānana i ka hopena o ka hoʻohuihui nui ʻana a i ʻole lawa ʻole i ka hana ʻana o ke kaʻa; ma ka ʻaoʻao ʻē aʻe, loaʻa ka naphthalene superplasticizer i ka hoʻololi maikaʻi ʻana me nā mea hoʻohui ʻē aʻe, a hiki ke hoʻohana nui ʻia e like me ka hoʻohui ʻana o nā mea hoʻohui i hui ʻia, e like me ka pumping agent, waterproofing agent, air-entraining water reducer, antifreeze, etc. nā mea hoʻemi hoʻemi kiʻekiʻe. He mea hana wai; ʻO ka hope loa, ʻoi aku ka maikaʻi o ke kumukūʻai a hiki ke ʻae ʻia e ke kaiāulu ʻenekinia. No laila, ua lilo nā superplasticizer kiʻekiʻe o ka naphthalene i mea waiwai nui o nā superplasticizers kiʻekiʻe i koʻu ʻāina a ua lilo i ʻano like ʻole.
ʻOiai he nui nā pōmaikaʻi o ka mea hoʻohaʻahaʻa wai kiʻekiʻe o ka naphthalene, aia kekahi mau hemahema, no ka mea, he hopena maikaʻi ʻole ia i ka paʻa ʻana o ka plastic. ʻOi aku ka nui o ka pohō i ka manawa o ke koʻi me ka hoʻohana ʻana i ka naphthalene superplasticizer ma mua o ko Benchmark concrete; ʻoiai he kiʻekiʻe ka nui o ka hoʻohaʻahaʻa wai, paʻakikī naʻe e hoʻokō i nā koi o ke kaila me ka nui o ka hoʻohaʻahaʻa wai kiʻekiʻe, a ma ka haʻahaʻa wai-binder ratio Ke hoʻohana ʻia i loko o ka pahu hana kiʻekiʻe kiʻekiʻe, e hoʻopilikia ʻia kona viscosity. He ʻano nui ka paʻakai, ʻaʻole kūpono i ke kūkulu ʻana. No ka hoʻomaikaʻi piha ʻana i ka hana o ka naphthalene-based high-efficiency water reducer, pono e hoʻohana ʻia kēia mau ʻano: E hoʻohui i nā mea hoʻohui kōkua (huihui) i ka naphthalene-based high-efficiency water-reducer e hoʻopau i kona mau hemahema. Ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻonui ʻia nā superplasticizers naphthalene ma o ka hoʻololi ʻana i nā ʻāpana molekala (ke kaumaha molekala, ka hāʻawi ʻana i ke kaumaha molekala, degere sulfonation) a i ʻole ke hoʻololi ʻana i kahi ʻāpana o ka naphthalene me nā monomers kūpono e hana i nā copolymers.
