If it is idle for more than 1 month, the polyurethane foaming opportunity will be blocked and your equipment will be paralyzed. The isocyanate component in the black material system of the polyurethane foaming machine will crystallize if it does not flow for a long time. So what we have to do is to maintain the polyurethane foaming equipment.
1. Stop for 10-20 days, and start the equipment for 3-5 minutes every 10-20 days to allow the raw materials to circulate under high pressure.
2. Long-term discontinuation can clean the entire system of black material, if it can be cycled regularly, it does not need to be cleaned.
3. The equipment should be placed in a cool and ventilated place, and must not be exposed to the sun. Keep the surface of the equipment clean and oil-free, especially the panel of the electrical cabinet and the instrument panel of the electrical appliance should be kept clean.
4. Regularly replace the O-ring inside the gun head, and replace the material pump shaft sealing ring according to the actual situation.
