Tetrakis(hydroxymethyl)phosphonium sulfate, with the CAS number 55566 - 30 - 8, is a chemical compound available at the best price from factory supply. It has a unique molecular structure. The molecular formula of tetrakis(hydroxymethyl)phosphonium sulfate is C4H16O8P2·H2SO4. It is a white to off - white crystalline powder. The compound has good solubility in water, which makes it suitable for various applications in aqueous systems.
It typically has a specific gravity within a certain range that can be determined through laboratory analysis. The purity of the product supplied from the factory is usually very high, meeting strict quality standards. This ensures its effectiveness and reliability in different industrial and commercial uses.
Tetrakis(hydroxymethyl)phosphonium sulfate has a wide range of applications. In the textile industry, it is used as a flame retardant. When applied to fabrics, it can significantly improve their fire - resistant properties. This is crucial for applications where fire safety is a major concern, such as in the production of curtains, upholstery, and children's clothing.
In the pulp and paper industry, it can be used as a biocide. It helps to control the growth of bacteria, fungi, and other microorganisms in the pulp and paper manufacturing process. This prevents the formation of slime and improves the quality of the final paper product.
It also has applications in the water treatment field. As a corrosion inhibitor, it can protect metal pipes and equipment from corrosion in water systems. Moreover, it can be used to remove heavy metals from water through chemical reactions, making it an important chemical for water purification.
When using Tetrakis(hydroxymethyl)phosphonium sulfate as a flame retardant in the textile industry, it is usually dissolved in water to form a solution. The fabric is then immersed in this solution for a certain period of time, followed by a drying process. The concentration of the solution and the immersion time need to be carefully controlled according to the type of fabric and the required fire - resistant level.
In the pulp and paper industry, it can be added directly to the pulp at a specific stage of the manufacturing process. The dosage should be determined based on the characteristics of the pulp and the level of microbial contamination.
For water treatment applications, it can be added to the water system in a continuous or batch - wise manner. The dosage depends on the water quality, the type of metal to be protected, and the concentration of heavy metals in the water.
Case 1: A textile company in Europe was facing challenges in meeting the strict fire - safety regulations for their curtain products. They decided to use Tetrakis(hydroxymethyl)phosphonium sulfate as a flame retardant. After carefully formulating the treatment solution and applying it to their curtains, they found that the fire - resistant performance of the curtains improved significantly. The curtains passed all the relevant fire - safety tests, which not only helped the company comply with the regulations but also enhanced their market competitiveness.
Case 2: A pulp and paper mill in Asia was struggling with slime formation in their production process, which led to poor paper quality and increased production costs. By adding Tetrakis(hydroxymethyl)phosphonium sulfate as a biocide at the appropriate stage of the process, they were able to effectively control the microbial growth. The slime problem was eliminated, and the quality of the paper products improved. This also reduced the maintenance cost of the equipment and increased the production efficiency.
Case 3: A water treatment plant in North America was dealing with high levels of heavy metals in the raw water. They used Tetrakis(hydroxymethyl)phosphonium sulfate to remove these heavy metals. By adjusting the dosage and the treatment process, they were able to reduce the heavy metal concentration in the treated water to an acceptable level. This ensured the safety of the water supply and protected the environment.
