ʻO Polycarboxylate Superplasticizer High Range Water Reducers no ka Cementitious Mortar
1. ʻO nā super plasticizers he mau surfactants hydrodynamic (nā mea hana reactive surface) no ka hoʻokō ʻana i ka hana kiʻekiʻe ma kahi ratio w/c i hoʻemi ʻia ma ka hōʻemi ʻana i ka friction ma waena o nā grains.
2. ʻO nā Superplasticizers, i ʻike ʻia hoʻi he mau mea hoʻemi wai kiʻekiʻe, he mau mea hoʻohui i hoʻohana ʻia no ka hana ʻana i ka sima ikaika kiʻekiʻe a i ʻole e kau i ka sima ponoʻī. He mau hui kemika nā Plasticizers e hiki ai ke hana i ka sima me kahi o 15% ka emi ʻana o ka wai.
3. ʻO PC seris kahi polymer Poly carboxylate holomua nona ka hopena hoʻopuehu ikaika loa a hōʻike i ka hoʻemi ʻana i ka wai kiʻekiʻe a me ke kahe ʻana o ke koko, ua hoʻohui ʻia i ka hana ʻana o ka sima hana kiʻekiʻe a hui pū ʻia me ka sima, ka aggregate, a me ka admixture.

ʻO ka Sulphonated Melamine Formaldehyde (SMF) Superplasticizer no nā Concrete Admixtures
1. ʻO Sulphonated Melamine Formaldehyde (SMF) ua kapa ʻia hoʻi ʻo Sulfonated Melamine Formaldehyde, Sulfonated Melamine Formaldehyde Condensate, Sodium Melamine Formaldehyde. He ʻano ʻē aʻe ia o ka superplasticizer ma waho aʻe o Sulphonated Naphthalene Formaldehyde a me Polycarboxylate superplasticizer.
2. ʻO nā super plasticizers he mau surfactants hydrodynamic (nā mea hana reactive surface) no ka hoʻokō ʻana i ka hana kiʻekiʻe ma kahi ratio w/c i hoʻemi ʻia ma ka hōʻemi ʻana i ka friction ma waena o nā grains.
3. Ma ke ʻano he mau mea hoʻohuihui e hōʻemi ana i ka wai, ʻo Sulfonated melamine formaldehyde (SMF) kahi polymer i hoʻohana ʻia i loko o nā sima a me nā ʻano hana plaster e hōʻemi i ka nui o ka wai, me ka hoʻonui ʻana i ka wai a me ka hana o ka hui ʻana. I loko o nā concretes, ʻo ka hoʻohui ʻana o SMF i kahi hoʻolālā hui kūpono e hopena i ka porosity haʻahaʻa, ka ikaika mechanical kiʻekiʻe, a me ka pale ʻana i nā kaiapuni hoʻouka kaua.

ʻO Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) no ka hoʻohuihui ʻana o ka sima
1. ʻO ka sodium naphthalene sulfonate formaldehyde FDN ua kapa ʻia hoʻi ʻo naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. ʻO kona helehelena ka pauka ʻeleʻele māmā. Hana ʻia ka SNF superplasticizer me ka naphthalene, sulfuric acid, formaldehyde a me ke kumu wai, a ke hele nei i kahi moʻo o nā hopena e like me ka sulfonation, hydrolysis, condensation a me ka neutralization, a laila maloʻo i loko o ka pauka.
2. Ua kapa pinepine ʻia ʻo Naphthalene sulfonate formaldehyde he superplasticizer no ka sima, no laila he kūpono loa ia no ka hoʻomākaukau ʻana o ka sima ikaika kiʻekiʻe, ka sima i hoʻōla ʻia i ka mahu, ka sima wai, ka sima impermeable, ka sima wai ʻole, ka sima plasticized, nā kila kila a me ka sima i hoʻoikaika ʻia. Eia kekahi, hiki ke hoʻohana ʻia ka sodium naphthalene sulfonate formaldehyde ma ke ʻano he mea hoʻolaha i nā ʻoihana ʻili, lole a me ka dye, a pēlā aku. Ma ke ʻano he mea hana ʻoihana o ka naphthalene superplasticizer ma Kina, hāʻawi mau ʻo Longou i ka pauka SNF kiʻekiʻe a me nā kumukūʻai hale hana no nā mea kūʻai aku āpau.
