Introduction
Analysis of the core content of the standard
This standard puts forward comprehensive technical requirements for fireworks and firecrackers mixing equipment, with key specifications:
- Equipment classification: Clarify the different technical paths of dry mixing equipment (processing dry materials) and wet mixing equipment (processing wet materials)
- Safety design: Requires 8 key safety measures such as explosion-proof, anti-static, and interlock control
- Material restrictions: It is stipulated that drug-related components must use anti-static materials with a resistance value of 5×10⁴Ω-1×10⁸Ω
Comparison of key technologies
| Indicators | Dry mixing equipment | Wet mixing equipment |
|---|---|---|
| Explosion-proof level | Isolation control + video surveillance is required | Explosion-proof switch is required |
| Workshop requirements | ≥16㎡+8m isolation control room | Conventional explosion-proof workshop |
| Safety device | Over/intrusion shutdown + water seal system | Basic explosion-proof measures |
Implementation points
Typical application scenarios
When a fireworks factory uses YBJ-T-GHY-10/30 dry mixing equipment, special attention should be paid to the following:
- Before daily operation, check the ground resistance ≤100Ω
- Mixed container temperature monitoring ≤60℃
- When using charcoal powder simulation test, the burning rate deviation should be <5%
Compliance recommendations
Enterprise implementation path
- Equipment selection: Give priority to models with triple interlock (overload/intrusion/temperature)
- Staff training: Focus on strengthening the 7 startup inspection processes specified in Appendix B
- Maintenance cycle: It is recommended to conduct anti-static material resistance testing every quarter (according to GB/T31838)
