Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) ee isku darka la taaban karo
1. Sodium naphthalene sulfonate formaldehyde FDN waxa kale oo loo yaqaan naphthalene ku salaysan superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde.Muuqaalkeedu waa budada khafiifka ah ee brown.SNF superplasticizer wuxuu ka samaysan yahay naphthalene, sulfuric acid, formaldehyde iyo saldhig dareere ah, waxaana lagu sameeyaa falcelin taxane ah sida sulfonation, hydrolysis, uumi iyo dhexdhexaadin, ka dibna la qalajiyey budo.
2. Naphthalene sulfonate formaldehyde waxaa caadi ahaan loo tixraacaa sida superplasticizer for shubka, sidaas darteed waxay si gaar ah ugu habboon tahay diyaarinta shubka xoogga badan, shubka uumiga lagu daaweeyay, shubka dareeraha ah, shubka aan la taaban karin, shubka biyaha aan biyaha lahayn, shubka caagga ah, biraha birta ah iyo prestressed. shubka la xoojiyay.Intaa waxaa dheer, sodium naphthalene sulfonate formaldehyde sidoo kale waxaa loo isticmaali karaa sida kala firdhiso maqaarka, dharka iyo warshadaha dheeha, iwm. Sida soo saaraha xirfadeed ee superplasticizer naphthalene ee Shiinaha, Longou had iyo jeer waxay bixisaa tayada sare ee budada SNF iyo qiimaha warshadda dhammaan macaamiisha.

Polycarboxylate Superplasticizer Heerarka Sare ee Biyaha Hooseeya ee Hoobiyaha Sibidhka
1. Balaastiijiyeyaasha aadka u sarreeya ayaa ah kuwa hawada sare (hydrodynamic surfactants) (wakiilada falcelinta dusha sare) si loo gaaro karti-shaqayn sare marka loo eego saamiga w/c la dhimay iyada oo la dhimayo khilaafka u dhexeeya badarka.
2. Superplasticizers, oo sidoo kale loo yaqaano yaraynta biyaha kala duwan, ayaa ah waxyaabaha lagu daro ee loo isticmaalo samaynta shubka xoogga badan ama in la dhigo shubka is-cusub.Plasticizers waa isku-dhisyo kiimiko ah oo awood u siinaya soo saarista shubka oo leh qiyaastii 15% ka kooban biyaha.
3. PC seris waa polymer-ka-horumarsan ee Poly-carboxylate kaas oo leh saamayn awood badan oo kala firdhisa oo muujisa kala-soocidda yaraynta biyaha iyo dhiig-baxa, waxaa lagu daraa wax-soo-saarka shubka waxqabadka sare leh oo lagu daray sibidhka, wadar ahaan, iyo isku-darka.

Sulphonated Melamine Formaldehyde (SMF) Superplasticizer ee isku-darka la taaban karo
1. Sulphonated Melamine Formaldehyde (SMF) waxa kale oo loo yaqaan Sulfonated Melamine Formaldehyde, Sulfonated Melamine Formaldehyde Condensate, Sodium Melamine Formaldehyde.Waa nooc kale oo superplasticizer ah marka laga reebo Sulphonated Naphthalene Formaldehyde iyo Polycarboxylate superplasticizer.
2. Balaastiijiyeyaasha sare waa kuwa hawada sare (hydrodynamic surfactants) (wakiilada falcelinta dusha sare) si loo gaaro karti-shaqayn sare marka loo eego saamiga w/c la dhimay iyadoo la yareynayo khilaafka u dhexeeya badarka.
3. Sida biyo dhimista isku-darka, Sulfonated melamine formaldehyde (SMF) waa polymer loo isticmaalo sibidhka iyo qaabaynta ku salaysan balaastarka si loo yareeyo nuxurka biyaha, iyada oo la kordhinayo dareeraha iyo shaqada isku dhafka.Isku-dhafka, ku-darka SMF ee naqshadaynta isku dhafka habboon waxay keenaysaa porosity hoose, xoog farsamo oo sarreeya, iyo iska caabin la wanaajiyey ee jawiga gardarrada ah.
