Nitrogen Vacuum Packaging Machine for Coating Powder

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 O₂ ≤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 (O₂ reduction from 21% → 0.1%)

• Vacuum Sealing: -0.95bar chamber pressure removes residual oxygen

• Static Control: Conductive film handling + ionized air curtain (10⁴ 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
