Understanding Gypsum Powder: Composition and Properties
Gypsum powder is primarily calcium sulfate dihydrate (CaSO4·2H2O). Its unique properties make it suitable for a wide range of applications. It’s relatively soft, easily workable, and possesses excellent fire resistance. The powder’s ability to set and harden when mixed with water is key to its use in construction materials. Companies like trusus.com showcase the use of gypsum powder in their gypsum boards.
Technical Features of Gypsum Powder
Different applications require varying gypsum powder specifications. The fineness, setting time, and strength are crucial parameters. These characteristics are influenced by processing methods and additives. The following table summarizes key technical features:
| Feature | Description | Measurement Units |
|---|---|---|
| Particle Size | Average diameter of gypsum powder particles | Micrometers (µm) |
| Setting Time | Time taken for the gypsum paste to harden after mixing with water | Minutes |
| Compressive Strength | Resistance to crushing force after setting and hardening | MPa |
| Water Retention | Ability to hold water during the setting process | Percentage (%) |
| Whiteness | Measure of the lightness and purity of the gypsum powder’s color | Percentage (%) |
| Density | Mass per unit volume of the gypsum powder | kg/m³ |
Types of Gypsum Powder and Their Applications
Gypsum powder isn’t a monolithic product. Its properties can be tailored for specific purposes through processing and additives. This results in various types, each suited to particular applications. Here’s a comparison:
| Type of Gypsum Powder | Key Characteristics | Primary Applications |
|---|---|---|
| Construction Grade Gypsum | High purity, controlled setting time, good strength | Plaster, wallboard, cement retarder |
| High-Strength Gypsum | Enhanced compressive strength, rapid setting | High-load-bearing applications, specialized molds |
| Medical Grade Gypsum | High purity, fine particle size, biocompatible | Dental casts, medical molds |
| Agricultural Gypsum | Contains sulfur, improves soil structure | Soil amendment, fertilizer |
| Art Grade Gypsum | Very fine particle size, high whiteness, slow setting | Sculpting, molding, decorative plasterwork |
