Ngā Whakaiti Wai Awhe Teitei mō te Mota Sima Polycarboxylate Superplasticizer
1. Ko ngā super plasticizer he surfactants hydrodynamic (ngā kaihoko tauhohenga mata) hei whakatutuki i te kaha mahi teitei i te ōwehenga w/c iti mā te whakaiti i te waku i waenga i ngā kakano.
2. Ko ngā superplasticizer, e mōhiotia ana ko ngā whakaiti wai awhe teitei, he tāpiringa e whakamahia ana mō te hanga raima kaha-teitei, hei whakatakoto rānei i te raima whakakīkī-ake. Ko ngā plasticizer he matū e āhei ai te hanga raima me te iti iho o te wai i te 15%.
3. Ko te PC seris he pūmua Polycarboxylate matatau, he kaha ake te pānga horapa, ā, he nui te whakaiti i te wehenga me te toto o te wai, ka tāpirihia ki te hanga raima mahi teitei, ka honoa ki te sima, te kohatu, me te ranunga.

Te Whakapūmau i te Pūmua Melamine Formaldehyde (SMF) mō ngā Ranunga Konukuraiti
1. Ko te Sulphonated Melamine Formaldehyde (SMF) e kiia ana ko te Sulfonated Melamine Formaldehyde, te Sulfonated Melamine Formaldehyde Condensate, te Sodium Melamine Formaldehyde. Ko tētahi atu momo superplasticizer i tua atu i te Sulphonated Naphthalene Formaldehyde me te Polycarboxylate superplasticizer.
2. Ko ngā super plasticizer he surfactants hydrodynamic (ngā kaihoko tauhohenga mata) hei whakatutuki i te kaha mahi teitei i te ōwehenga w/c iti mā te whakaiti i te waku i waenga i ngā kakano.
3. Hei ranunga whakaiti wai, ko te Sulfonated melamine formaldehyde (SMF) he pūmua e whakamahia ana i roto i ngā sima me ngā hanganga pāreti hei whakaiti i te nui o te wai, me te whakanui ake i te rere me te ngāwari o te mahi o te ranunga. I roto i ngā raima, ko te tāpiri o te SMF ki te hoahoa ranunga tika ka hua ake he iti ake te porosity, he kaha ake te miihini, me te ātete pai ake ki ngā taiao kaha.

Te Konutai Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) mō te Ranunga Konukuraiti
1. Ko te formaldehyde konutai naphthalene sulfonate FDN e kiia ana hoki ko te superplasticizer e hangai ana ki te naphthalene, te poly naphthalene sulfonate, te naphthalene formaldehyde kua sulphonated. Ko tōna āhua he paura parauri mārama. Ko te superplasticizer SNF he mea hanga mai i te naphthalene, te waikawa whanariki, te formaldehyde me te turanga wai, ā, ka pāngia e te raupapa o ngā tauhohenga pēnei i te sulfonation, te hydrolysis, te condensation me te neutralization, kātahi ka whakamarokehia hei paura.
2. E kiia ana te naphthalene sulfonate formaldehyde he superplasticizer mō te raima, nō reira he tino pai mō te whakarite i te raima kaha-teitei, te raima whakamaroke-mamao, te raima wai, te raima ātete-wai, te raima kirihou, ngā pae maitai me te raima whakapakari kua whakakahangia. Hei tāpiri, ka taea hoki te whakamahi i te sodium naphthalene sulfonate formaldehyde hei whakamarara i roto i ngā ahumahi hiako, kakahu me te tae, me ētahi atu. Hei kaihanga ngaio o te naphthalene superplasticizer i Haina, ka whakarato tonu a Longou i te paura SNF kounga teitei me ngā utu wheketere mō ngā kiritaki katoa.
