Description and advantages
-
As a kind of concrete superplasticizer, SNF powder has a strong dispersing effect on cement particles and the higher water reduction rate (15%～25%).
-
So it can be widely used in the construction industry.
-
Especially for the preparation of large-flow concrete, cast-in-place concrete and prefabricated components with early strength and high strength requirements, sodium naphthalene has a good use effect and can comprehensively improve and improve various properties of concrete.
-
In addition, SNF superplasticizer is also highly utilized in various industries such as agriculture, plastics and rubber, papermaking, textiles and petroleum, etc.
Applications
-
This chemical is suitable for many types of cement. Such as Portland cement, ordinary Portland cement, Portland slag cement, Portland fly ash cement, etc.
-
It has a good effect on preparing a variety of concretes. For example, high-strength concrete, high-performance concrete, steamed concrete, large-fluid concrete, pumped concrete, etc. Of course, it is also particularly suitable for concrete construction in winter.
-
Kingsun SNF superplasticizer can be widely used in highways, bridges, tunnels, water conservancy and hydropower projects, ports, docks, skyscrapers, power engineering, industrial and civil buildings, prestressed components, etc.
Determine the dosage:
Determine the dosage of naphthalene sulfonate formaldehyde to the specific requirements of concrete, test conditions and water reduction requirements. Generally speaking, the dosage of SNF based admixture is usually 0.5% to 1% of the cement mass, and the recommended dosage is 0.7%. However, the specific dosage needs to be determined through experiments.
Solution method:
Dissolve SNF superplasticizer powder in water according to the determined dosage to form a uniform solution. During the concrete mixing process, add the solution to the mixer along with the mixing water.
Dry doping:
Add SNF powder directly to the mixer together with other concrete materials (such as cement, aggregate, etc.). Ensure that the water reducer powder can be fully mixed with other materials during the mixing process.
Stirring and mixing:
Regardless of the method of addition, it should be ensured that the SNF sodium naphthalene sulfonate formaldehyde is evenly distributed in the concrete. Appropriately extend the mixing time to ensure the mixing effect. During use, the dosage of SNF high-efficiency water reducer should be strictly controlled to ensure accurate measurement.
