Quick Lime（Calcium Oxide ) is an extensively utilized chemical compound across various industries. It exists as a white, highly caustic, alkaline, and crystalline solid at room temperature, exhibiting distinct physical characteristics that make it indispensable in numerous applications. The typical appearance of quick lime is a pristine white powder, which, when contaminated with impurities, can turn a light yellow or gray hue. One notable physical property of this compound is its hygroscopicity, meaning it has the ability to absorb moisture from the surrounding environment. This characteristic is particularly significant in industries where moisture control is crucial.
Calcium oxide has important applications in the production of lubricating grease
Calcium oxide reacts with fatty acids through a saponification reaction to produce calcium fatty acid soaps, which are important thickening agents in lubricating grease.The calcium fatty acid soaps form a three - dimensional network structure in the base oil, entrapping the base oil and giving the lubricating grease its appropriate consistency and stability. Factors such as the purity and particle size of calcium oxide, as well as the reaction temperature, time, and stirring speed, affect the saponification reaction. Higher purity and smaller particle size of calcium oxide, along with appropriate increases in temperature, reaction time, and stirring speed, are beneficial for improving the efficiency and product quality of the saponification reaction.

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.
