Ko nga superplasticizers naphthalene-basedKo te tikanga ka mahia ma te whakamahi i te naphthalene ahumahi (he naphthalene parakore ranei i etahi wa) hei rauemi mata. Ko te tukanga whakaputa: Ka huri te Naphthalene hei hua paura na roto i te sulfonation, hydrolysis, condensation, neutralization, filtration, me te whakamaroke rehu. Ko te tukanga whakaputa osuperplasticizer raupapa naphthalenekua pakeke, kua tau te mahi hua. I tetahi taha, ka taea te whakamahi tika i te hua i roto i te raima hokohoko, a ko te mahi o te raima hokohoko a te kaihoko whakaheke wai kua kaha te nuinga o nga miihini. Ka taea hoki te matapae te paanga o te nui rawa, te kore rawa ranei o te whakaranu ki te mahi o te raima arumoni; i tetahi atu ringa, naphthalene He pai te urutau ki etahi atu whakaurunga, ka taea te whakamahi whanui hei hanganga o nga whakauru whakauru, penei i nga miihini pupuhi, nga taputapu parewai, nga taputapu whakaheke wai, te antifreeze, me etahi atu, me te naphthalene pea kei roto i tona hanganga He mea tino kaha ki te whakaheke wai; ka mutu, he nui te whai huatanga o te utu, ka whakaaetia e te hapori miihini. No reira, ko te naphthalene-a-te-nui-a-te-te-wai-whakaiti kua riro hei hua auraki o te kai-whakaiti wai-nui o Haina, a, kua waiho hei momo tino whakamahia.
