Technical Highlights
Original Asymmetric Flow Channel Reconstruction Design for Maximized Mixing Uniformity
Adopt an original asymmetric flow channel separation and reorganization structure, composed of mixing units alternately formed by circular curved tubes and rectangular straight tubes, with a cyclic cross layout to form intense chaotic convection in the chamber. After diversion at the feed inlet, the raw materials accelerate to form a high-speed jet in the tapered tube and collide violently with the fluid in the straight tube, increasing the raw material contact area by more than 40% compared with the traditional structure and fundamentally solving the problem of uneven mixing of multi-component raw materials, with a mixing uniformity of ≥98%.
Three-component Synchronous Metering Technology for Precise and Controllable Dynamic Proportioning
The alloy steel mixing head is matched with a high-torque metering pump to realize the dynamic synchronous proportioning of A/B/C three-component polyurethane raw materials, ensuring the precision of raw material mixing ratio from the source. Combined with the closed-cell foaming process, the tire density and hardness error are ≤1.5%, the finished product wear resistance is increased by 25%, the tear resistance is enhanced by 30%, and the service life breaks through industry standards.
