Overview
Hydrated lime powder is a calcium-based compound produced by slaking quicklime (calcium oxide) with water. This process creates a fine, dry powder with excellent binding and stabilizing properties. The material has been used for centuries in construction and agriculture due to its versatility and cost-effectiveness. In modern applications, hydrated lime powder serves as a crucial component in various industrial processes. Its ability to modify pH levels, stabilize soils, and react with various compounds makes it indispensable in construction projects, environmental remediation, and manufacturing processes.
Physical and Chemical Properties
Hydrated lime powder appears as a white, odorless powder with a slightly bitter taste. It has a high pH (approximately 12.4 in saturated solutions), making it strongly alkaline. The material undergoes carbonation when exposed to air, slowly converting back to calcium carbonate. The powder exhibits poor solubility in water but forms a suspension called limewater. When mixed with water, it produces heat through an exothermic reaction. Its particle size typically ranges between 1-10 microns, contributing to its reactivity and workability in various applications.
Main Applications
In construction, hydrated lime powder is primarily used for soil stabilization, particularly in road base preparation and foundation work. It improves load-bearing capacity and reduces plasticity in clay soils. The material also serves as an ingredient in mortar and plaster mixes, enhancing workability and durability. Environmental applications include water treatment (pH adjustment and heavy metal removal) and flue gas desulfurization. In agriculture, it functions as a soil amendment to neutralize acidic soils and provide calcium nutrients. The food industry uses food-grade hydrated lime in products like corn tortillas and pickles.
Safety and Storage
Hydrated lime powder requires careful handling due to its caustic nature. Workers should wear protective gloves, goggles, and dust masks to prevent skin irritation, eye damage, or respiratory issues. The material should be stored in moisture-proof containers to prevent premature carbonation and clumping. Proper ventilation is essential when working with hydrated lime powder to avoid dust accumulation. In case of contact with skin or eyes, immediate flushing with water is necessary. Storage areas should be clearly marked and separated from acids and other incompatible materials.
B2B Procurement Guide
When procuring hydrated lime powder for industrial use, buyers should specify the required purity level (typically 90-95% for most applications). Packaging options range from 25kg bags to bulk shipments in tanker trucks or super sacks for large-scale projects. Quality indicators include fineness (measured by particle size distribution), available lime content, and moisture percentage. Buyers should request material safety data sheets (MSDS) and certificates of analysis from suppliers. For consistent supply, establish relationships with manufacturers who can provide batch-to-batch consistency and reliable delivery schedules.
