The high-pressure foaming machine is a kind of equipment in which polyether polyols and polyisocyanates are foamed by chemical reaction in the presence of a variety of chemical hoeing agents such as foaming agents, catalysts, emulsifiers and so on. The high-pressure foaming machine is not equipped to produce uniform and qualified foam products, so it is very popular in the market.
Pay attention to cleaning the polyurethane high-pressure foaming machine in normal use. One of the important steps in the cleaning of the heating pipe of the polyurethane high-pressure foaming machine. When spraying is finished, press the pressure relief button and then fire the gun to relieve the pressure to about 50-70psi. At this time, the pressure relief button indicator will go out. You can also see if the piston rod of the proportional cylinder has been retracted into the cylinder. If it has retracted, the pressure relief can be stopped.
Because when there is a certain pressure in the pipe, the moisture in the air will not easily enter the pipe, ensuring that the raw material is not affected by the humid air, and the A material will not deteriorate and crystallize in the pipe. This method is very harmful to the maintenance of the equipment during the daily use. helpful.
