High Quality sodium 2 - naphthalenesulfonate with CAS number 532 - 02 - 5 is a chemical compound that is widely used in various industries. This product is known for its high quality and comes at the best price in the market.
Chemical Formula: C₁₀H₇SO₃Na
Molecular Weight: Approximately 242.22 g/mol
Appearance: Usually appears as a white to off - white powder
Solubility: It is soluble in water, which makes it convenient for many applications.
This product has a wide range of uses across different industries. In the textile industry, sodium 2 - naphthalenesulfonate is used as a leveling agent and dispersant. It helps in ensuring an even distribution of dyes on the fabric, resulting in a more uniform coloration. This leads to higher - quality finished textile products.
In the construction industry, it can be used as a concrete admixture. It improves the workability of concrete by reducing its water demand without sacrificing strength. This allows for easier placement and compaction of concrete, ultimately enhancing the durability and quality of concrete structures.
Furthermore, in the paper industry, it serves as a wet - end additive. It can improve the retention of fillers and fine fibers, leading to better paper formation and improved physical properties of the paper, such as strength and smoothness.
When using sodium 2 - naphthalenesulfonate, it is crucial to follow proper handling and usage procedures. First, ensure that you are wearing appropriate personal protective equipment, such as gloves and safety goggles, to avoid direct contact with the product.
If using it in a textile dyeing process, dissolve the required amount of the product in water according to the recommended dosage. Then, add the solution to the dye bath. Stir the bath thoroughly to ensure uniform distribution of the product before adding the fabric for dyeing.
For concrete admixture use, add the product to the concrete mixture during the mixing process. The dosage should be carefully controlled based on the specific requirements of the concrete project. It is advisable to conduct small - scale tests before large - scale application to determine the optimal dosage.
In the paper industry, add the product to the pulp suspension at the wet - end stage. Mix it well to ensure proper dispersion and interaction with the pulp fibers and fillers.
Case 1: Textile Dyeing
A textile factory was facing issues with uneven coloration of their cotton fabrics. They decided to use our high - quality sodium 2 - naphthalenesulfonate. By adding 1 - 2% of the product (based on the weight of the fabric) to the dye bath, they achieved a significant improvement in color uniformity. The fabric quality improved, and the rejection rate due to color defects decreased from 10% to less than 2%.
Case 2: Construction Project
A large - scale building project required high - strength and workable concrete. The construction company used sodium 2 - naphthalenesulfonate as a concrete admixture. They added 0.5 - 1% of the product by weight of the cement. The concrete became more workable, which made it easier to pour and compact. As a result, the compressive strength of the concrete increased by 15 - 20% compared to the concrete without the admixture, ensuring the long - term durability of the building.
Case 3: Paper Manufacturing
A paper mill was struggling with low filler retention and poor paper formation. After adding 0.1 - 0.3% of sodium 2 - naphthalenesulfonate to the pulp suspension, they observed a significant improvement in filler retention. The paper became stronger and smoother, which increased its market competitiveness.
