2. Ke hoʻohana pū ʻia me nā ʻano mea hoʻohaʻahaʻa wai ʻē aʻe, ʻaʻohe hopena superimposed.

I ka wā ma mua, i ka wā e hoʻomākaukau ai i ka lāʻau lapaʻau, hiki ke hoʻololi ʻia ke ʻano o ka mea hoʻoheheʻe e like me ka makemake, a ʻaʻole ʻokoʻa loa nā waiwai o ka hui ʻana i ka ʻiʻo mai nā hopena o ka lab, ʻaʻole hoʻi e loli koke i nā waiwai o ka hui ʻana. .

Ke hoʻohana ʻia ka polycarboxylic acid-based water-reducing agents i hui pū ʻia me nā ʻano mea ʻē aʻe o nā mea hoʻohaʻahaʻa wai, paʻakikī ke loaʻa nā hopena superimposed, a me ka solubility like ma waena o ka polycarboxylic acid-based water-reducing agent solutions a me nā ʻano wai ʻē aʻe. ʻAʻole maikaʻi loa ka hoʻonā ʻana i nā mea hana hoʻohaʻahaʻa.

3. ʻAʻohe hopena hoʻololi ma hope o ka hoʻohui ʻana i nā mea hoʻololi maʻamau.

I kēia manawa, liʻiliʻi ka hoʻopukapuka ʻana i ka noiʻi ʻepekema e pili ana i ka polycarboxylic acid-based water-reduce agents. I ka hapanui o nā hihia, ʻo ka pahuhopu o ka noiʻi ʻepekema ʻo ia wale nō ka hoʻomaikaʻi ʻana i kāna hopena plasticizing a me ka hoʻohaʻahaʻa wai. He paʻakikī ke hoʻolālā ʻana i nā hale molekala e like me nā pono ʻenekinia like ʻole. ʻO kahi pūʻulu o ka polycarboxylic acid-based water reducing agents me nā hopena hoʻopaneʻe a me nā hopena wikiwiki, ʻaʻohe ea-entraining a i ʻole nā ​​​​mea hoʻoheheʻe ea ʻē aʻe, a hoʻohui ʻia nā viscosities like ʻole. Ma muli o ka ʻokoʻa a me ka paʻa ʻole o ka cement, admixtures, a aggregates i nā papahana, he mea nui loa i nā mea hana admixture a me nā mea hoʻolako e hoʻohui a hoʻololi i nā huahana hoʻohui wai polycarboxylate e like me nā pono o ka papahana.

I kēia manawa, ʻo nā hana ʻenehana no ka hoʻololi pū ʻana o nā mea hoʻohaʻahaʻa wai e pili ana i nā ana hoʻololi o nā mea hoʻohaʻahaʻa wai maʻamau e like me lignosulfonate series a me naphthalene series high-efficiency water-reducing agents. Ua hōʻike ʻia nā hoʻāʻo ʻaʻole kūpono nā hana ʻenehana hoʻololi i hala no nā mea hoʻemi wai i hoʻokumu ʻia i ka waika polycarboxylic. No ka laʻana, ma waena o nā mea hoʻopaneʻe i hoʻohana ʻia no ka hoʻololi ʻana i nā mea hoʻohaʻahaʻa wai i hoʻokumu ʻia i ka naphthalene, ʻaʻole kūpono ka sodium citrate no nā mea hoʻemi wai i hoʻokumu ʻia i ka waika polycarboxylic. ʻAʻole wale ia he hopena hoʻopaneʻe, hiki iā ia ke hoʻolōʻihi i ka coagulation, a me ka solution sodium citrate ʻO ka miscibility me ka polycarboxylic acid-based water reducing agents he ʻilihune loa.

Eia kekahi, ʻaʻole kūpono nā ʻano mea hoʻoheheʻe, nā mea hoʻoheheʻe ea a me nā mānoanoa no nā mea hoʻohaʻahaʻa wai i hoʻokumu ʻia i ka waika polycarboxylic. Ma o nā ho'āʻo a me ka nānā ʻana i luna, ʻaʻole paʻakikī ke ʻike ma muli o ke ʻano o ka molecular structure o polycarboxylic acid-based water reducing agents, e pili ana i ka hohonu o ka noiʻi ʻepekema a me ka hōʻiliʻili ʻana o ka ʻike noiʻi ʻenehana i kēia manawa, ka hopena. o ka polycarboxylic acid wai-reducing agents ma polycarboxylic acid-based superplasticizers ma o kekahi mau mea kemika ʻAʻole nui nā ala e hoʻololi ai i nā mea hoʻohaʻahaʻa wai, a ma muli o nā kumumanaʻo a me nā kūlana i hoʻokumu ʻia i ka wā ma mua no ka hoʻololi ʻana i nā ʻano mea hoʻemi wai. nā mea hana, pono paha ka ʻimi hohonu a me ka noiʻi ʻana no nā mea hoʻohaʻahaʻa wai e pili ana i ka polycarboxylate. Hana i nā hoʻoponopono a me nā hoʻohui.

4. He ʻilihune loa ka paʻa hana o ka huahana.

ʻAʻole nui nā hui hoʻoheheʻe wai hoʻohaʻahaʻa i hiki ke manaʻo ʻia he ʻoihana kemika maikaʻi. Noho wale nā ​​hui he nui i ka pae hana mua o nā mixers a me nā mīkini pahu, a ua kaupalena ʻia ka maikaʻi o ka huahana e ka maikaʻi o ka masterbatch. E pili ana i ka mana o ka hana ʻana, ʻo ka instability o ke kumu a me ka maikaʻi o nā mea maka he kumu nui ia e hoʻopilikia ai i ka hana o nā superplasticizers hoʻokumu ʻia polycarboxylic acid.
