Sulphonated Melamine Formaldehyde Resin Based Superplasticizer
Sulphonated Melamine Formaldehyde Resin Based Superplasticizer SMF-10 . SMF-10 is a Sulphonated Melamine Formaldehyde Resin Based Superplasticizer, suitable for cement-based or gypsum-based mortars that require high fluidity and high strength. Range of Application
Sulphonated Melamine Formaldehyde Condensate - an overview
Sulphonated melamine formaldehyde condensates are synthetic polymers that have the structural formula with each repeating unit containing one sulphonate group. The condensation number ( n) is usually in the range 50–60 giving a molecular weight between 12,000 and 15,000. 6.4.2 Sulphonated naphthalene formaldehyde condensates
CBD-203. Superplasticizers in Concrete - NRC-IRC
Superplasticizers are broadly classified in four groups, viz, sulphonated melamine-formaldehyde condensates (SMF), sulphonated naphthalene-formaldehyde condensates (SNF), modified lignosulphonates (MLS), and others including sulphonic acid esters, carbohydrate esters, etc. variations exist in each of these classes and some formulations may
Superplasticizer Function and Sorption in High Performance
These categories are as follows: sulphonated naphthalene formaldehyde condensates (SNF) sulphonated melamine formaldehyde condensates (SMF) modified lignosulphonates (MLS), and others, including sulphonic acid esters and carbohydrate esters.
Super Plasticizers: Classification and Uses | Concrete Technology
The super plasticizers are used for the following purposes: 1. To increase the workability of concrete without any change in the composition of the mix. 2. To reduce the water content of mixing water, to reduce the water/cement ratio resulting in increase of strength and durability of concrete. 3.
- Is SMF a soluble melamine formaldehyde resin based superplasticizer?
- SMF is a soluble melamine formaldehyde resin based superplasticizer. It has no air-entraining. A chloride free admixture based on melamine formaldehyde, formulated for the production of rheoplastic concrete. Available as a liquid, or in powder form which must be dissolved in water prior to use.
- What is melamine based superplasticizer (SMF)?
- Sulfonated melamine formaldehyde resin (SMF), usually referred to as melamine based superplasticizer or SMF superplasticizer, is also one of the most important concrete admixtures. It is white powder in appearance, easily soluble in water, non-toxic, non-irritating, non-flammable, high water reduction rate and low chloride ion content.
- What is SMF sulphonated melamine formaldehyde?
- SMF sulphonated melamine formaldehyde is a concrete water water with excellent performance. It can be adsorbed on the surface of cement particles and disperse the cement particles through electrostatic repulsion and steric hindrance effect, thereby significantly reducing the amount of mixing water without changing the slump of concrete.
- What is sulfonated melamine formaldehyde used for?
- Sulfonated Melamine Formaldehyde is used as asuperplastiziser to produce free flowing concrete in: Sulfonated Melamine Formaldehyde is used as a water-reducer in the manufacture of high early strength concrete for: It is also used for high strength gypsum,gypsum based self-leveling,wall plaster,gypsum based putty powder etc.
- Is SMF a chloride-free admixture?
- SMF is a soluble melamine formaldehyde resin based superplasticizer. It has no air-entraining. A chloride-free admixture based on melamine formaldehyde formulated for the production of the plastic concrete. SMF is a soluble melamine formaldehyde resin based superplasticizer. It has no air-entraining.
- Is melamine superplasticizer a good water reducing agent?
- As an anionic high efficiency water reducer, melamine superplasticizer has a strong adsorption and dispersion effect on cement, so SMF is also one of the concrete water reducing agents with better comprehensive indicators. Sulfonated melamine formaldehyde (SMF) superplasticizer is an anionic surfactant.
