Factory Supply Sodium Disilicate N-Hydrate with the CAS number 13870-28-5 is a water - soluble inorganic compound. It has a chemical formula that may vary depending on the degree of hydration. The compound usually appears as a white or colorless solid, which can be in the form of powder or granules.
Some of its important physical and chemical parameters include a relatively high melting point, and it is stable under normal storage conditions. It is soluble in water, forming an alkaline solution. The pH value of its aqueous solution is typically in the alkaline range, which reflects its chemical reactivity.
Sodium Disilicate N-Hydrate has a wide range of applications across different industries.
In the detergent industry, it is used as a builder. It can enhance the cleaning power of detergents by softening water, preventing the precipitation of metal ions, and acting as an emulsifier and dispersant. This helps in better removal of dirt and stains from fabrics and hard surfaces.
In the paper industry, it is used as a coating and sizing agent. It can improve the strength, smoothness, and water - resistance of paper products. Moreover, it can also enhance the ink absorption properties of paper, which is crucial for printing applications.
In the construction industry, it can be used as an additive in concrete. It can improve the workability, strength, and durability of concrete. It also helps in reducing the porosity of concrete, making it more resistant to water penetration and chemical corrosion.
When using Sodium Disilicate N-Hydrate, it is important to follow proper safety procedures. Wear appropriate personal protective equipment, such as gloves and goggles, as it can be irritating to the skin and eyes.
For its use in detergents, it is usually added to the detergent formulation during the manufacturing process. The amount added depends on the specific formulation requirements and the desired cleaning performance.
In the paper industry, it can be applied as a solution on the paper surface. The solution concentration and the application method (such as spraying or dipping) need to be carefully controlled to achieve the desired properties of the paper.
In the construction industry, it can be mixed with the concrete mixture. The mixing time and the proportion of Sodium Disilicate N - Hydrate added should be determined based on the type of concrete and the construction requirements.
Case 1: Detergent Manufacturing
A detergent manufacturing company was facing issues with poor stain removal and hard - water performance in their products. They decided to add Sodium Disilicate N - Hydrate to their detergent formulation. After adding the compound at an appropriate concentration, they found that the detergents showed significantly improved cleaning power. The softening of water by the compound reduced the formation of soap scum, and the dispersant property helped in better suspension of dirt particles, resulting in cleaner clothes.
Case 2: Paper Production
A paper mill wanted to improve the quality of their printing paper. They applied a Sodium Disilicate N - Hydrate solution on the paper surface. The treated paper had better smoothness, which improved the printing quality. The water - resistance also increased, preventing ink from smudging. As a result, the paper became more suitable for high - quality printing jobs.
Case 3: Concrete Construction
A construction company was working on a project in a coastal area where the concrete structures were exposed to saltwater. They added Sodium Disilicate N - Hydrate to the concrete mixture. The compound reduced the porosity of the concrete, making it more resistant to saltwater penetration and corrosion. This increased the lifespan of the concrete structures, saving the company on future repair and maintenance costs.
