About polyurethane sandwich panel foaming principle:
All of them introduce gas into the aqueous solution of foaming agent, but different types of pu sandwich panel foaming machines introduce gas in different ways. Knowing the type of foaming machine will know the way it introduces gas, which will be of great help to further understand its technical characteristics and use performance, and help producers to grasp the overall.
If you choose the low-speed mixing type is relying on slow rotating blades to introduce gas, the bubble yield is small and the foaming efficiency is low.
If you choose the high pressure gas introduction method, the size of the bubble diameter can not be controlled, the foam is not uniform; high pressure and low and medium pressure type bubble production speed, high efficiency, uniform and small bubbles.
