Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) mo Fa'afefiloi Sima

fa'amatalaga puupuu:

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.

Talosaga

➢ Lelei fetuutuunai i ituaiga uma o sima, faʻaleleia le faʻaogaina o sima, faʻaaogaina lautele i auala, nofoaafi, Alalaupapa, tunnels, eletise, DAMS, fale maualuluga ma isi galuega.

1. Fa'afefiloi fuala'au ile 0.5%-1.0%,0.75% fa'afefiloi fuala'au fautuaina.

2. Saunia fofo pe a manaomia.

3. Fa'aaoga sa'o o le sui o le pa'u ua fa'atagaina, i le isi itu o le fa'aopoopoga o le so'o e soso'o ma le fa'asusu vai(vai-sima fua:60%).

Fa'atinoga Autu

➢ E mafai e le SNF-A ona tu'uina atu le paluga vave fa'apipi'i saosaoa, maualuga le liquifying a'afiaga, maualalo le ea entraining aafiaga.

➢ O le SNF-A e fetaui lelei ma ituaiga sima po'o gypsum binders, isi mea fa'aopoopo e pei o le mea e fa'amama ai le fa'afu'a, mafiafia, fa'aluma, mea fa'alautele, fa'avave ma isi.

➢ SNF-A e fetaui lelei mo le pa'u ta'ele, fa'ameamea fa'alelei, sima foliga fa'alelei fa'apea fo'i fa'ama'a fola lanu.

Galuega Fa'atino

➢ E mafai ona fa'aogaina le SNF e fai ma susū mo le paluga fa'afefiloi mago ina ia maua ai le fa'aogaina lelei.

☑ Teuina ma le tuʻuina atu

E tatau ona teuina ma tuʻuina atu i lalo o tulaga mamago ma mama i lona uluai afifi ma alu ese mai le vevela. A maeʻa ona tatalaina le afifi mo le gaosiga, e tatau ona toe faʻamaufaʻailogaina faʻamau ina ia aloese mai le faʻaogaina o le susu.

☑ Ola fa'asa

Ole ola ole 10 masina.Faʻaaoga i le vave e mafai ai i lalo o le maualuga o le vevela ma le susu, ina ia aua neʻi faʻateleina le avanoa o le keke.

☑ Saogalemu o oloa

Naphthalene based superplasticizer SNF-A e le o se mea mata'utia. O isi fa'amatalaga e uiga i itu saogalemu o lo'o tu'uina atu i le Pepa o Fa'amatalaga Saogalemu Mea.

Muamua: Sulphonated Melamine Formaldehyde(SMF) Superplasticizer mo mea fa'afefiloi sima.
