Explosion-Proof Borosilicate Glass Lens for Mining Lamp and Hazardous Area Lighting

‌

1. Material Composition:

• Reinforced Borosilicate Glass: High-purity material (Schott B270 or equivalent) with tempered strengthening for impact resistance.

• Explosion-Proof Encapsulation: Stainless steel or brass housing with flame-arresting grooves and tempered sealing gaskets.

2. Key Properties:

• Explosion Resistance: Certified for ATEX/IECEx Zone 1 & 2 (gas) and Zone 21 & 22 (dust) hazardous environments.

• Thermal Shock Tolerance: Withstands ΔT > 150°C (e.g., rapid cooling from 300°C to room temperature).

• Mechanical Strength: IK10 impact rating and 6.5 Mohs hardness to resist abrasion and flying debris.

• Chemical Inertness: Resists corrosion from acids, alkalis, and solvents (excluding HF).

3. Core Functions:

• Flame Containment: Prevents internal sparks or explosions from igniting external flammable atmospheres.

• Optical Clarity: >92% light transmission with minimal distortion for uniform illumination in low-visibility environments.

• Environmental Sealing: IP67-rated protection against dust, moisture, and corrosive gases.

4. Applications:

• Mining Lamps: Cap lamps, tunnel lighting, and explosion-proof handheld lamps for underground coal mines.

• Oil & Gas Facilities: Hazardous area lighting for refineries, drilling platforms, and petrochemical plants.

• Chemical Processing: Lighting for explosive atmosphere workshops, storage areas, and reaction chambers.

• Grain & Powder Industries: Dust-proof lighting for silos, mills, and pharmaceutical production zones.
