Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) mo Fa'afefiloi Sima
1. Sodium naphthalene sulfonate formaldehyde FDN ua taʻua foi naphthalene faavae superplasticizer, poly naphthalene sulfonate, sulfonated naphthalene formaldehyde.O lona foliga mai o le pauta lanu enaena.SNF superplasticizer e faia i le naphthalene, sulfuric acid, formaldehyde ma le faʻavae vai, ma e oʻo i se faasologa o gaioiga e pei o le sulfonation, hydrolysis, condensation ma le neutralization, ona faʻagogo lea i le paʻu.
2. Naphthalene sulfonate formaldehyde e masani ona taʻua o se superplasticizer mo sima, o lea e sili ona talafeagai mo le prepatation o le maualuga-malosi sima, ausa-faamalolo sima, vai sima, impermeable sima, susu susu, plasticized sima, uamea ma prestressed. sima fa'amalosi.E le gata i lea, o le sodium naphthalene sulfonate formaldehyde e mafai foi ona faʻaaogaina e avea o se faʻasalalau i le paʻu, ie ma le vali, ma isi. I le avea ai o se tagata faʻapolofesa faʻapolofesa o le naphthalene superplasticizer i Saina, Longou e tuʻuina atu i taimi uma le maualuga o le SNF paʻu ma tau falegaosimea mo tagata uma.

Polycarboxylate Superplasticizer Fa'aitiitiga Suavai Maualuga mo le Sima Sima
1. Super plasticizers o hydrodynamic surfactants (surface reactive agents) mo le ausiaina o galuega maualuga i se faʻaititia w / c ratio e ala i le faʻaitiitia o le feteʻenaʻiga i le va o fatu.
2. Superplasticizers, e taʻua foi o le faʻaitiitia o vai maualuga, o mea faʻapipiʻi e faʻaaogaina mo le faia o le sima malosi maualuga poʻo le tuʻuina o le sima faʻapipiʻi.Plasticizers o vailaʻau vailaʻau e mafai ai ona gaosia le sima pe a ma le 15% faʻaititia le vai.
3. PC seris o se polymer Poly carboxylate alualu i luma lea e sili atu le malosi dispersing aafiaga ma faʻaalia le faʻaitiitia o le vai maualuga segregation ma le toto, e faʻaopoopoina i le gaosiga o le sima maualuga faʻatinoga ma tuʻufaʻatasia ma sima, faʻapipiʻi, ma admixture.

Sulphonated Melamine Formaldehyde(SMF) Superplasticizer mo mea fa'afefiloi sima.
1. Sulfonated Melamine Formaldehyde (SMF) e taʻua foi Sulfonated Melamine Formaldehyde, Sulfonated Melamine Formaldehyde Condensate, Sodium Melamine Formaldehyde.O le isi ituaiga superplasticizer e ese mai le Sulphonated Naphthalene Formaldehyde ma le Polycarboxylate superplasticizer.
2. Super plasticizers o hydrodynamic surfactants (surface reactive agents) mo le ausiaina o galuega maualuga i se faʻaititia w / c ratio e ala i le faʻaitiitia o le feteʻenaʻiga i le va o fatu.
3. I le avea ai ma vai fa'aitiitia fa'afefiloi, Sulfonated melamine formaldehyde (SMF) o se polymer e fa'aaogaina i sima ma fa'apipi'i fa'avae e fa'aitiitia ai le vai, a'o fa'ateleina le sua ma le fa'aogaina o le fa'afefiloi.I totonu o sima, fa'aopoopoina o le SMF i se mamanu fa'afefiloi talafeagai e maua ai le fa'aitiitia o le porosity, maualuga le malosi fa'ainisinia, ma le fa'aleleia atili o le tete'e atu i si'osi'omaga saua.
