How to clean and maintain polyurethane spraying equipment in the later stage

Polyurethane spraying equipment has been widely used in the exterior wall thermal insulation spraying industry. In order to better complete the spraying work, the cleaning of spraying equipment such as polyurethane high-pressure spraying machines cannot be ignored. Next, let's take a look at how to carry out polyurethane. Cleaning of spraying equipment.

The first is the heating pipe of the polyurethane spraying equipment. When there is a certain pressure in the pipe, the moisture in the air is not easy to enter the pipe of the polyurethane spraying machine. Therefore, in order to ensure that the polyurethane raw material is not affected by the humid air, and the A material will not deteriorate or crystallize in the pipe, it can be The equipment is depressurized. This method is very helpful to maintain the equipment during the daily use of polyurethane spray equipment.

The second aspect is the A material suction pump of the polyurethane spraying equipment. In order to prevent the isocyanate component from reacting with the moisture in the air, causing the slowing down of the feed rate, the imbalance of the pumping ratio, and the occurrence of cavitation in the proportional pump. Therefore, after the equipment is used, clean the surface of the lifting pump with a cleaning agent, and put it into a protective sleeve containing the host cleaning agent to seal the lifting pump.

The third aspect, of course, must not forget the cleaning of the entire polyurethane spraying equipment. If the construction interval reaches more than 30 days, the entire A material system must be thoroughly cleaned and sealed to avoid affecting normal use next time.
