Product Description:
Sodium metasilicate pentahydrate is a white, crystalline solid with a characteristic appearance. It is highly soluble in water, dissolving readily to form an alkaline solution. This compound has a molar mass that takes into account its five water molecules of crystallization. In the cleaning industry, it serves as a powerful degreasing agent. It can effectively break down and remove tough grease and oil stains from various surfaces, whether in industrial settings, kitchens, or on machinery. In the water treatment field, it can be used to adjust the pH of water, helping to create a more favorable environment for other treatment processes. Additionally, it can act as a water - softening agent by reacting with certain metal ions in water. In the ceramic industry, it plays a role in improving the bonding and shaping of ceramic materials during production. It helps in the formation of a stronger and more uniform ceramic structure. In the textile industry, it can be used in pre - treatment processes to remove impurities from fabrics and enhance the effectiveness of subsequent dyeing and finishing operations. However, when handling sodium metasilicate pentahydrate, care must be taken as it can cause skin and eye irritation. It should be stored in a dry place to prevent the loss of its water of crystallization and maintain its chemical properties.
Application:
Sodium metasilicate pentahydrate has various applications. In cleaning, it powerfully degreases surfaces, removing tough grease and oil. In water treatment, it adjusts pH and softens water by reacting with metal ions. In ceramics, it improves the bonding and shaping of materials for a stronger structure. In textiles, it pre - treats fabrics, removing impurities to enhance dyeing and finishing. Caution is needed during handling as it may irritate skin and eyes, and it should be stored dry to maintain its properties.
