Official Website: www.cncalcium.com

850 Mesh 98% Calcium Hydroxide is a high-quality powder material integrating high purity, ultra-fineness and strong reactivity. It is produced by advanced wet slaking and precision classification grinding processes. With the main component content reaching over 98% and ultra-fine 850-mesh particle size, the product ensures uniform dispersion and large specific surface area. It features stable physical and chemical properties and excellent reaction activity, meeting the sophisticated application requirements of environmental protection, chemical industry, food and pharmaceutical, agriculture and other fields. It is an ideal upgraded alternative to ordinary calcium hydroxide.

Core Features

High purity guarantee: The content of active ingredients reaches over 98%, and the contents of impurities such as magnesium, silicon, and aluminum oxides are extremely low. Heavy metal residues (such as lead and arsenic) are far below industry standards, avoiding interference from impurities on the application effect.

Ultra-fine structure: 850 mesh corresponds to an extremely fine particle size, belonging to the category of high-numbered powder. The particles are fine and smooth, have good dispersibility and are not prone to agglomeration. The specific surface area is significantly increased, providing sufficient active sites for efficient reactions.

Stable physical and chemical properties: The appearance is pure white powder, with strong alkalinity and high reactivity. It performs outstandingly in neutralization reactions, adsorption purification and other scenarios. At the same time, the drying loss is low and the storage stability is good.

 Company Profile

Changshu Hongyu Calcium Co., Ltd. was founded in 1984. The company has always been focused on the research, development and production of three major series of products: calcium oxide, calcium hydroxide and calcium carbonate, with a daily output of 600 tons. After more than 40 years of professional accumulation, relying on advanced production technology and strict quality control, the company has accumulated rich production experience. Our products are of high purity and low impurity, and are widely used in various fields such as chemical industry, environmental protection, agriculture and construction. With high-quality products and a good market reputation, our products are not only favored in the domestic market, but also exported to well-known enterprises in Southeast Asia, the Middle East, Africa and other regions, becoming a trusted choice for many international customers.

We have our own mine in Hubei Province, and in 2024, we invested to establish a new company: Carlison New Materials (Jingshan) Co.,Ltd., which covers an area of 40,000 square meters. The new company specializes in the production of fine chemical, pharmaceutical and food-grade calcium oxide and calcium hydroxide products. Changshu Hongyu will continue to adhere to the concept of innovation, quality and service, constantly enhance its competitiveness, provide high-quality calcium compound products and services for more industries, and work with all sectors to create a better future.

Main Application Fields :

Environmental Protection Field

Acidic Wastewater Treatment: Efficiently neutralizes acidic sewage, quickly adjusts pH value, and adsorbs heavy metal ions to form precipitates, reducing water pollution.

Flue Gas Desulfurization: Used in flue gas desulfurization systems of coal-fired power plants, steel plants, etc. It reacts with SO₂ to generate calcium sulfite, featuring high desulfurization efficiency and controllable cost.

Food & Pharmaceutical Field

Food Processing: Used as an acidity regulator in the production of fruit juice, beer, dairy products to adjust the pH of products; also can be used as a calcium nutrition fortifier added to complementary food and plant milk.

Pharmaceutical Manufacturing: Applied in the preparation of dental filling materials and drug sustained-release carriers. Its high-purity characteristic meets the quality standards of the pharmaceutical industry.

Chemical & Material Field

Fine Chemicals: Serves as a precursor for synthesizing high-end materials such as nano-calcium carbonate and hydroxyapatite; also can be used as a catalyst carrier to improve the efficiency of catalytic reactions.

Rubber & Building Materials: Acts as a filler for plastics and rubber to improve the heat resistance and mechanical properties of products; added to cement, it can enhance slurry fluidity and early strength.

Agriculture & Soil Remediation

Soil Improvement: Adjusts the pH value of acidic soil and supplements calcium elements in the soil. Its ultra-fine particle size ensures uniform dispersion, quick effect and no damage to soil structure.

Pesticide Carrier: Used as a carrier for pesticide powder to realize the slow release of pesticide components and prolong the duration of pesticide effect.

Production Workshops

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.
