Calcium hydroxide can also be called Hydrated Lime,Calcium hydroxide is a strong base with bactericidal and preservative properties. It has a corrosive effect on skin and fabrics. It reacts with acids to form corresponding calcium salts.Calcium hydroxide as an additive is widely used in various chemical industries.
99% content Calcium hydroxide has advantages such as high purity and high activity, and high purity calcium hydroxide is widely used in fine chemical and other fields
High Purity: The high 99% content indicates that the product has a very high purity of calcium hydroxide with extremely low impurity levels. This enables it to provide more accurate and stable stoichiometry in various chemical reactions, ensuring the consistency and reliability of the reactions. In industries with strict purity requirements, such as pharmaceuticals, food additives, and electronics, high - purity calcium hydroxide can prevent impurities from affecting product quality and ensure the high quality of the final products.
High Reactivity: The high - purity calcium hydroxide has a relatively complete crystal structure with fewer surface defects. When reacting with other substances, it can come into more complete contact and react more fully, showing high reactivity. For example, in water treatment, it can more quickly and effectively react with acidic substances to rapidly adjust the pH value of water quality. In the process of flue - gas desulfurization, it can more efficiently react with acidic gases such as sulfur dioxide, improving the desulfurization efficiency.
Low Impurity Content: The low impurity content can reduce side reactions caused by impurities. In some fine - chemical production processes, impurities may react with other substances in the reaction system, generating unwanted impurities or by - products, which affects the purity and yield of the product. Calcium hydroxide with 99% content, due to its low impurity level, can effectively reduce the occurrence probability of side reactions, improve product purity and production efficiency. Meanwhile, the low impurity content also helps to reduce equipment wear and blockage. Impurities may cause corrosion and wear to production equipment, or form blockages in pipelines, reactors, and other equipment, affecting the normal operation of production. Using high - purity calcium hydroxide can prolong the service life of equipment and reduce equipment maintenance costs.
Good Solubility: In some applications where calcium hydroxide needs to be dissolved in water or other solvents, high - purity calcium hydroxide has better solubility. Because the presence of impurities may interfere with the dissolution process of calcium hydroxide or form insoluble substances in the solution, affecting the clarity and stability of the solution. Calcium hydroxide with 99% content can dissolve more quickly and completely, forming a clear and stable solution, which is convenient for subsequent processing and use. For example, in the preparation of calcium hydroxide solutions for chemical analysis, paint production, and other fields, good solubility can ensure the accuracy and uniformity of the solution concentration.
