Microcapsule Fire-Suppression Patch Feeding System
Designed for EV battery safety, this system mixes fire-suppressant microcapsules (e.g., perfluorohexanone) with silicone carriers under low shear for high uniformity, then feeds the blend precisely to coating heads or molds.
- Static mix, microcapsule breakage <0.5%
- Servo gear pump, ratio ±1%
- Two-component separate lines, own temp control
- 316 stainless mixer, quick-disassembly clean
- One-tap recipe call, data traceable
- Fits 10–200μm microcapsules
This feeding system is purpose-built for EV battery safety applications. It combines fire-suppressant microcapsules (such as perfluorohexanone) with a silicone carrier through low-shear, high-uniformity mixing, followed by continuous precision feeding. Ideal for automated production of inter-cell fire-suppression patches, energy-storage cabinet fire barriers, and similar products.
Core Design
- Static Mixing Protection: Multi-stage static mixing elements split, rotate, and recombine the stream. No moving parts contact the microcapsules, keeping breakage below 0.5%.
- Laminar Mixing: High-viscosity silicone (up to 500,000 cPs) and microcapsules are dispersed at a molecular level under minimal shear.
- Two-Component Precision Metering: Component A (silicone base + microcapsule premix) and Component B (curing agent) travel through independent, temperature-controlled lines.
- Servo Metering Pumps: High-precision gear pumps deliver a ratio accuracy of ±1% with an adjustable flow rate of 0.5–5 kg/min.
System Components
- Material Storage: Sealed A/B tanks with low-speed agitation to prevent settling. Temperature maintained at 20–80°C ±2°C.
- Metering & Delivery: Servo-driven high-precision gear pumps with real-time pressure monitoring and closed-loop control.
- Mixing System: 316 stainless steel mixer designed for quick disassembly and cleaning. Mixing uniformity ≥99%.
- Coating Control: Constant-pressure output supports continuous or intermittent feeding, compatible with various coating processes.
- Intelligent Control: PLC + HMI interface with one-touch recipe recall and traceable production data.
Technical Advantages
- Microcapsule Integrity: Breakage rate < 0.5%. Precise temperature control prevents thermal damage to capsule shells.
- Consistent Quality: Mixing uniformity CV ≤3%, batch viscosity fluctuation < 5%. Built for 24/7 continuous production.
- Efficient & Flexible: Production speed increased by over 150% compared to conventional processes. Material changeover time reduced by 70%.
- Safe & Eco-Friendly: Fully enclosed system achieves >98% material utilization. Noise level < 75 dB.
