Calcium Hydroxide Powder Manufacturing Facilities in China and Their Production Capabilities

Calcium Hydroxide Powder Factories in China An Overview

Calcium hydroxide, commonly known as slaked lime, is a versatile chemical compound with the formula Ca(OH)₂. It is widely used across various industries due to its significant properties, such as alkalinity, which make it suitable for a range of applications, including construction, water treatment, agriculture, and food processing. In recent years, China has emerged as a leading producer of calcium hydroxide powder, establishing numerous factories dedicated to its production. This article explores the landscape of calcium hydroxide powder factories in China, addressing their operations, technology, and market significance.

The Production Process

Calcium hydroxide powder is primarily produced by the hydration of quicklime (calcium oxide), which is obtained through the calcination of limestone. The production process typically involves the following steps

1. Limestone Quarrying Limestone is mined from quarries, where it is crushed and sized for processing. 2. Calcination The crushed limestone is heated in a kiln at high temperatures (approximately 900 to 1000°C) to produce quicklime. 3. Hydration The quicklime is then mixed with water, leading to an exothermic reaction that forms calcium hydroxide. This step is crucial as it dictates the purity and quality of the final product. 4. Milling and Packaging The resultant slaked lime is then dried, milled into a fine powder, and packaged for distribution.

China's advanced industrial infrastructure enables manufacturers to efficiently carry out these processes, ensuring that the calcium hydroxide powder produced meets stringent quality standards.

The calcium hydroxide powder factories in China are increasingly integrating modern technologies to enhance production efficiency and product quality. Automation and precision control systems are employed to monitor the hydration process, ensuring consistent results. Furthermore, many factories are investing in research and development to improve the purity levels of their products and to innovate in sustainable production methods.

Emission control technologies are also becoming a focal point for many producers, especially in light of growing environmental regulations. Innovative dust suppression and waste management techniques are being adopted to minimize the environmental footprint, aligning industrial operations with global sustainability goals.
