Sodium Polynaphthalene Sulfonate Concrete Superplasticizer SNF/ NSF/PNS/FDN
High Range Water Reducers Polynaphthalene Sulfonate(SNF-C1) Product Description:
Our company's technical team uses industrial naphthalene, sulfuric acid and formaldehyde as raw materials, through sulfonation, hydrolysis, condensation and neutralization, to obtain a naphthalene-based superplasticizer. The content of raw naphthalene, sulfuric acid species, ratio, reaction time, reaction The effect of temperature, acidity, and feeding method on the performance of naphthalene-based superplasticizers.
The results show that the best synthesis conditions are: naphthalene purity ≥95%, sulfuric acid content i>98%, sulfonation temperature 160～165℃, sulfonate Conversion time 2h, sulfonated acidity 32%, sulfuric acid is added dropwise, hydrolysis temperature 110℃, hydrolysis time 0.5h, acidity control during condensation 26%, condensation temperature 105-110℃, condensation time 2.5～3.0h, using lime milk Neutralize to pH=7-9.
When the content of naphthalene-based superplasticizer is 1%, it will compare with other similar products in the net slurry fluidity, compressive strength, water reduction rate, bleeding rate, and slump with time Comparing losses and other aspects, achieved better results, reduced product costs, and improved product performance.

SODIUM NAPHTHALENE SULFONATE POWDER can be used together with other concrete admixtures such as retarders, accelerators and air-entrains. It is compatible with most of the known brands, but we recommend to carry-out compatibility test under local conditions before using. The different admixtures should not be premixed but added separately to concrete.
High Range Water Reducers Polynaphthalene Sulfonate From a technical point of view alone, the addition of admixtures can bring the following benefits to concrete:
1) Improve the strength of concrete as required
Academic performance (enhancement, early strength, retardation, continuous coagulation, etc.).
2) Improve the workability of concrete as required (large fluidity, self-flowing Flat, self-filling, underwater pouring, sprayable construction, etc.).
3) Improve the durability of concrete and prolong the service life of structures Life.
4) Speed up the progress of the project, shorten the construction period, and accelerate the turnover of the template.
5) Save cement, save cost and cost, etc.
Our company can provide a variety of specifications Sodium naphthalene Sulphonate formaldehyde condensatio, waiting for you to choose, you are welcome to visit the factory and discuss cooperation.
