PERGUNTAS FREQUENTES

Q: What is an opaque quartz tube used for?

A: Opaque quartz tubes (also called milky or translucent quartz tubes) are primarily used in infrared heating systems, UV sterilization equipment, laboratory apparatus, industrial furnaces, and light source protection. Their key advantages include high temperature resistance (up to 1200°C), excellent thermal shock resistance, superior chemical resistance, and optimal light diffusion properties that make them ideal for applications requiring controlled radiation distribution.

A: TOQUARTZ® opaque quartz tubes can operate continuously at temperatures up to 1100-1200°C. For short-term applications, they can withstand temperatures up to 1450°C. The material has a melting point of 1732°C, softening point of 1630°C, and annealing point of 1180°C. It’s important to note that continuous operation near the maximum temperature may reduce the service life, and proper thermal ramping procedures should be followed to maximize durability.

A: Opaque quartz tubes exhibit exceptional chemical resistance, approximately 30 times greater than ceramics and 150 times greater than stainless steel when exposed to acids. They are inert to most chemicals, including strong acids, organic solvents, and corrosive gases, especially at elevated temperatures. The only significant exception is hydrofluoric acid (HF), which can etch and dissolve silica-based materials. This excellent chemical resistance makes them ideal for laboratory equipment, chemical processing, and aggressive industrial environments.

A: For optimal maintenance, clean opaque quartz tubes with acetone, isopropyl alcohol, or mild acid solutions (except HF). Avoid alkaline cleaners as they can damage the surface. For stubborn deposits, a solution of dilute sulfuric acid can be effective. Always handle with clean gloves to prevent oils and contaminants from affecting performance. Inspect regularly for devitrification (whitish, rough appearance) which indicates approaching end-of-life. Store in dry environments to prevent moisture absorption which can affect high-temperature performance.

A: Opaque quartz tubes enhance IR heating efficiency through optimal radiation diffusion. According to thermal efficiency studies from the International Journal of Heat and Mass Transfer, milky quartz tubes provide up to 18% more uniform heat distribution compared to clear tubes, leading to energy savings of 8-12% in industrial heating applications. The controlled light scattering properties create more consistent surface temperatures on target materials, reducing hotspots and improving process quality while lowering overall energy consumption.
