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.
High purity calcium hydroxide can be used in the production of sulfonates. In the production of sulfonates, calcium hydroxide mainly plays a role in neutralization. Sulfonates are usually prepared by the neutralization reaction of sulfonic acids with bases. As a base, calcium hydroxide can react with sulfonic acids to convert sulfonic acids into corresponding sulfonates. For example, in the production of petroleum sulfonates, petroleum fractions are sulfonated with fuming sulfuric acid or sulfur trioxide to obtain sulfonic acids, and then calcium hydroxide is used for neutralization to obtain sulfonate products such as calcium sulfonate.
The use of calcium hydroxide in the production of sulfonates has certain advantages. From the cost perspective, calcium hydroxide is widely available and relatively inexpensive, which can reduce the production cost. In terms of product performance, the calcium sulfonate salt produced has good detergency - dispersancy properties and acid - neutralizing ability, and is widely used in the field of lubricant additives. It can effectively prevent the formation of carbon deposits and sludge in engines and protect the engine.

Our Advantages
We have our own mine in Hubei Province, which endows us with the following advantages:
Stable Raw Material Supply: Owning our own mine ensures a stable supply of raw materials for calcified substances. This helps to avoid production interruptions caused by issues such as fluctuations in the raw material market and supply shortages. It guarantees the smooth progress of production plans and maintains a stable product output, enabling us to better meet customer needs and enhance customer satisfaction.
Controllable Raw Material Quality: Our company can directly manage and monitor the mining process of the mine, and strictly control the quality of raw materials. We are able to select appropriate ore grades and qualities according to production requirements, ensuring that the mined ore meets the high standards of our products. This provides a solid foundation for producing high-quality calcified substance products and helps to enhance the market competitiveness of our products.
Cost Advantage: Obtaining raw materials from our own mine reduces intermediate procurement links and lowers procurement costs. Moreover, in the long run, a stable raw material supply also enables our company to take the initiative in cost control and avoid the risk of cost increases due to fluctuations in raw material prices, thereby improving the company's economic benefits and profitability.
