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 You can also see if the piston rod of the proportional cylinder has been retracted into the cylinder.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.

The electric sprayer has the advantages of simple structure, convenient operation, few failures, easy maintenance, low price, stable pressure, long operation time, wide application range and so on. There are many herbicide formulations, and different formulations have different formulation methods.
1. Unique impermeability:Rigid foam is a dense microcellular foam with a closed cell rate of more than 92% and a smooth self-skin. It is an excellent anti-seepage material.The rigid foam layer has no joints and is completely impermeable to water, which fundamentally eliminates the possibility of roo
Problems that should be paid attention to before and after use of polyurea spraying equipment:First of all, after spraying every day, or when changing the variety of spraying materials, the residual materials of spraying equipment and conveying pipelines should be removed, preferably once a day. The
