Application Areas
High-end Polyurethane Coating Process Field
Core-adapted to the polyurethane coating production in high-end fields such as automotive interiors, electronic encapsulation and waterproof rolls, and able to meet the high-quality coating requirements of various substrates including films, fabrics and composite materials. It can accurately process special raw materials such as high-filling wear-resistant materials, high-viscosity elastomers (≤5000cP) and medical-grade polyurethanes requiring trace additives, taking into account batch large-scale production and small-batch customized coating, and covering industrial-grade, precision electronic-grade and medical-grade full-dimensional coating needs.
Technical Highlights
E-type multi-stage spiral mixing technology for ultra-high uniformity + low bubble residue
The original multi-stage staggered spiral blade structure enables A/B two-component raw materials to form micro-laminar mixing with a uniformity of ≥99.5% (ASTM D3795 standard). Meanwhile, the optimized flow channel design reduces bubble generation to achieve mixing with low bubble residue, fundamentally avoiding defects such as uneven thickness and bubbles in coated finished products.
PID intelligent constant temperature mixing chamber with ±0.5℃ precise temperature control for stable processes
The mixing chamber is built with a professional PID temperature control module, featuring a temperature control precision of ±0.5℃ and a range of 20-80℃. It effectively avoids polyurethane raw material viscosity changes caused by temperature fluctuations, eliminates coating deviations due to uneven raw material viscosity, and ensures the stability of the coating process and consistency of finished products throughout the process.
Super-hard alloy head with tungsten carbide coating for super wear resistance and adaptability to various harsh raw materials
Key parts of the mixing head are coated with tungsten carbide, which is corrosion and wear resistant, and the core components have a service life of over 100,000 hours. It can stably adapt to the processing of various polyurethane raw materials such as high-filling, high-viscosity (≤5000cP) and medical-grade ones, meeting both continuous industrial production needs and the precise control of trace additive ratios, with extremely strong adaptability.
Flexible production + high-compatibility design for high efficiency, material saving and easy integration
It supports 8-hour continuous batch production with 12% raw material loss saved; parameters can be quickly adjusted without disassembly for small-batch customization, achieving high material changeover efficiency. The standardized interface can be seamlessly connected to mainstream coater guide rails and feeding systems without modifying existing production lines, and the foam density deviation can be maintained within ±2% after long-term use, realizing stable and efficient output of the production line.
