Working principle of polyurethane foaming machine

Polyurethane foam machine is inserted into the industrial vat equipped with components A and B through two lifting pumps, and the materials come out of the lifting pump. As the feed pipe enters the main machine, it is mixed and output at a certain volume ratio 1: 1 in the main machine.

After the material is output, it passes through the thermal insulation hose to reach the spray gun. After pulling the trigger, it passes through the filter in each direction through the high-pressure impact mixing in the mixing chamber, and then sprays out at a high speed. Upper curing molding.

According to the function of polyurethane spraying machine, it has sprayability and perfusion type:

The sprayable polyurethane foaming machine is mainly used in the construction industry, specifically for large-scale thermal insulation equipment such as polyurethane foam insulation of exterior walls of buildings, integration of roofing polyurethane foam insulation and waterproofing, and cold storage polyurethane foam insulation lamps.

The perfusion type polyurethane foaming machine is mainly suitable for the filling and filling of the interlayer thermal insulation layer of the solar water heater barrel, the thermal insulation water tank, the car portable refrigerator and other small thermal insulation tools.
