Product Name:99.5% content of Calcium Hydroxide with 325-mesh size.

Calcium Hydroxide with a purity level of 99.5% offers a multitude of applications due to its strong basic characteristics and high purity. Below is a detailed description of its various applications:

1. Wastewater Treatment

One of the primary applications of 99.5% purity Calcium Hydroxide is in wastewater treatment plants. It is used to adjust the pH of wastewater, making it more suitable for subsequent treatment processes. By neutralizing acidic or alkaline substances, Calcium Hydroxide helps to maintain a stable pH environment, ensuring the effectiveness of other treatment methods.

2. Water and Sewage Treatment

In addition to wastewater treatment, Calcium Hydroxide is also used as a flocculant in water and sewage treatment. Its high purity ensures efficient coagulation and flocculation of suspended particles, improving water clarity and reducing the load on subsequent treatment stages. This contributes to producing cleaner and safer water for human consumption and environmental release.

3. Soil Improvement

Calcium Hydroxide can be used to improve soil quality by neutralizing soil acidity and increasing its pH value. This is particularly beneficial for acidic soils, where it helps to release nutrients bound by aluminum and manganese, making them more available to plants. By improving soil structure and fertility, Calcium Hydroxide supports healthier plant growth and crop yields.

4. Pharmaceutical and Cosmetic Industry

In the pharmaceutical and cosmetic industries, Calcium Hydroxide with 99.5% purity is used as a raw material for the production of various products. Its strong basic properties make it suitable for reactions that require alkaline conditions. Additionally, its purity ensures that the final products meet high quality and safety standards.

5. Chemical Synthesis and Catalysis

Calcium Hydroxide serves as a catalyst or reagent in various chemical syntheses. Its high purity ensures precise control over reaction conditions and product purity. For instance, it can be used in the preparation of phenolic-rich bio-oil from lignin pyrolysis, catalyzing reactions in a fluidized bed reactor. Similarly, it can act as a catalyst in the pyrolysis of pinewood in a fixed bed reactor.

6. Construction and Building Materials

Calcium Hydroxide is also used in the construction industry, particularly in the production of building materials such as lime mortar and lime concrete. Its reaction with water produces Calcium Carbonate, which contributes to the strength and durability of these materials. Additionally, Calcium Hydroxide can be used as a whitewash ingredient, providing a protective and decorative coating for buildings.

7. Other Applications

Beyond the aforementioned fields, Calcium Hydroxide with 99.5% purity has numerous other applications. It can be used as a lye substitute in non-lye hair relaxers, providing a safer and more gentle alternative to traditional methods. Additionally, it is used in the liming industry to neutralize acids and improve soil conditions for agriculture. Its versatility makes it a valuable material in a wide range of industries.

In conclusion, Calcium Hydroxide with a purity of 99.5% demonstrates its importance and versatility across various sectors. Its strong basic characteristics and high purity make it suitable for a multitude of applications, contributing to advancements in wastewater treatment, water and sewage treatment, soil improvement, pharmaceuticals, cosmetics, chemical synthesis, construction, and beyond.
