Sulphonated Naphthalene Formaldehyde Condensate
Sulfonated naphthalene formaldehyde condensates (PNS), also known as polynaphthalene sulfonates (PNS), have a weak interaction with clay minerals. They have a water reduction ability up to 30%. Polymelamine sulfonate (PMS) and sulfonated melamine formaldehyde condensate (PMS) demonstrate a possible decrease of the water content in concrete up
Superplasticizer
Idealized structure of naphthalenesulfonate /formaldehyde polymer used as a superplasticizer. Polycarboxylate displacement on a multi-phase suspension. The polymers that serve as plasticizers exhibit surfactant properties. They are often ionomers. They function as dispersants to minimize particle segregation (gravel, coarse and fine sands).
Superplasticizer - an overview | ScienceDirect Topics
Before treatment with sodium hydroxide and reacting with formaldehyde, PNS superplasticizer was obtained by sulfonation of naphthalene with sulfuric acid or SO 3. 8.2.2 Polymelamine sulfonates The PMSs have been used in the concrete industry since the 1970s.
Sulphonated Naphthalene Formaldehyde (SNF) - Kingsun Chemicals
Sulphonated naphthalene formaldehyde, also known as naphthalene superplasticizer or SNF superplasticizer, is a high-range water reducing admixture for concrete. It has the advantages of high water reduction rate, neither retardation nor air entrainment, and strong adaptability.
Sodium Naphthalene Sulfonate Formaldehyde (SNF/PNS/NSF/FND)
Naphthalene series superplasticizer (naphthalenesulfonic acid formaldehyde condensate) and some other chemical admixtures play an important role in modern concrete materials and technologies, which can improve various properties of concrete and promote the development of new concrete technologies.
- What is Sulphonated naphthalene formaldehyde?
- Sulphonated naphthalene formaldehyde, also known as naphthalene superplasticizer or SNF superplasticizer, is a high-range water reducing admixture for concrete. It has the advantages of high water reduction rate, neither retardation nor air entrainment, and strong adaptability.
- What is poly naphthalene sulfonate formaldehyde (SNF/NSF/PN?
- This concrete admixture is used to affect substantial water reduction to concrete without influencing normal setting time and further improves the durability, workability, and strength of concrete. Poly Naphthalene Sulfonate Formaldehyde (SNF/NSF /PNS) complies with the requirements of the following standards: ASTM C 494, Type F; ASTM C 1017 .
- What is ACC naphthalene sulfonate superplasticizer?
- This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. ACC naphthalene sulfonate superplasticizers are with efficient water reduction. They can be used to prepare high strength concrete, flow concrete, impermeable concrete, etc.
- What is sodium naphthalene sulfonate superplasticizer?
- The sodium naphthalene sulfonate superplasticizer can be used directly or dissolved in water first and used as a solution-type admixture, which is suitable for various construction environments or mixer types.
- How Sulphonated naphthalene can improve the workability of concrete?
- It has the advantages of high water reduction rate, neither retardation nor air entrainment, and strong adaptability. So sulphonated naphthalene can greatly improve the workability of concrete and reduce the water consumption for mixing, and can significantly increase the strength of concrete.
- What is naphthalene series superplasticizer?
- Naphthalene series superplasticizer and some other chemical admixtures play an important role in modern concrete materials and technologies, which can improve various properties of concrete and promote the development of new concrete technologies.
