Foaming machine

The WH-PU-6-40 six-component continuous high-pressure foaming machine adopts an online mixing mode of low-pressure premixing and high-pressure collision. This method adopts the characteristics of low-pressure high-speed shear mixing and high-pressure collision mixing. It is currently the most effective foaming machine for pentane and pir. The six components are 1 polyether (polyester) POLY, 2 isocyanate ISO, 3 TCPP, 4 catalyst katA, 5 catalyst katB, 6 pentane foaming agent treibmittel, and each component is measured separately, the magnetic coupling and frequency conversion motor are used to drive the high-precision pump (note; the German radial piston pump cannot be magnetically connected). Through the high-precision volume and mass flowmeter (catalyst, foaming agent), the flow rate is controlled in a closed loop, and the system can automatically change the output flow rate and mixing ratio instantaneously. The working mode of this system is continuous on-line mixing. Because pentane is more difficult to dissolve in polyether than 141B, when producing pir, the amount of catalyst and foaming agent is especially small, which brings difficulty to mixing. The high-speed shear micro-premixing method can completely solve these two problems. Polyether, flame retardant, foaming agent and catalyst are input to the dynamic mixer through their respective metering units for high-speed shear stirring and premixing. In order to improve the foaming effect and fully integrate the mixed polyether into the foaming nucleation gas, we have adopted a set of high-precision gas metering devices to add the gas into the mixed polyether for high-speed shear emulsification and gas-liquid micro-mixing to achieve the nucleation effect.
