Usage Guidelines for Fused Quartz Curved Plates
Handling and Storage
- Always wear clean, lint-free gloves when handling quartz plates to prevent surface contamination
- Store in a clean, dry environment away from potential impact sources
- Keep plates separated using lint-free paper or foam spacers to prevent scratching
- Avoid sudden temperature changes during storage, which can create thermal stress
Performance Optimization
- For optical applications, maintain the surfaces free of dust and fingerprints
- In heating applications, ensure proper thermal expansion allowance
- For electrical insulation applications, keep surfaces clean and free of conductive contaminants
- Periodically inspect for signs of surface degradation in long-term installations
Installation Recommendations
- Use mounting systems that accommodate thermal expansion
- Avoid direct metal-to-quartz contact by using PTFE or silicone gaskets
- Ensure mounting pressure is evenly distributed to prevent stress concentration
- Allow for expansion clearance in high-temperature applications
Cleaning Procedures
- Clean with deionized water and mild detergent for general applications
- For more stubborn contaminants, use isopropyl alcohol or acetone
- Ultrasonic cleaning in deionized water is effective for precision applications
- Always air dry or use filtered compressed air to prevent spotting
