Polyurethane foaming machine can make foaming agents manufactured in a concentrated aqueous solution, and the foaming agent itself does not automatically foam. The mechanical effect of the foam machine is foamed. The foaming machine and foaming agent are mutually cooperative technical systems and cannot play their own role alone.
The characteristic of polyurethane foaming machine is continuous suppression, foaming, forming and sawing. It can make a variety of large, medium and small composite boards. Because of its high production efficiency and stable product quality, it is a relatively advanced production process. Disposable composite board production lines are mainly composed of single -layer and multi -layer crusher and foaming machines.
Craft characteristics: press the wooden board tightly, and then foam. It is suitable for products with thicker production, large quantity, more specifications and size products.
If the pressure of polyurethane foaming machine is too low, the dual -component will not be able to combine the foam rate, but if the pressure is too high, the process requirements of the entire equipment will be high. Temperature also has a great impact on the foam rate. If the temperature is too high, the response rate will be very fast, and other equipment and processes need to be used to adapt. If the temperature is too low, the reaction will be slow and curing long, which will affect production accordingly. Therefore, the design process should control the temperature within the range of 65 ± 1 ° C according to the requirements of the process.
