- Brand： glzon
- Model： GZM-50A
Product Overview: Combustible Powder Safety Solution
Shanghai Guangzhi Automation's Nitrogen Vacuum Packaging Machine revolutionizes the packaging of flammable coating powders (epoxy, polyester, acrylic). Engineered with ATEX Zone 21 certification, it achieves O? ≤0.1% and -0.95bar vacuum in sealed bags/kegs, eliminating explosion risks while extending shelf life by 300%.
Core Explosion-Proof Technology
1. Triple Safety Barrier
Nitrogen Purging: 3-stage gas displacement (O? reduction from 21% → 0.1%)
Vacuum Sealing: -0.95bar chamber pressure removes residual oxygen
Static Control: Conductive film handling + ionized air curtain (10? Ω resistance)
2. ATEX-Certified Components
Explosion-proof servo motors (Ex d IIC T4)
Intrinsically safe HMI (24VDC operation)
Pressurized control cabinet (IP66)
3. Precision Powder Handling
Loss-in-Weight Filling: ±0.2% accuracy for 1-25kg bags
Anti-Caking System: Ultrasonic vibrators prevent bridging in hopper
