As a high-quality and demanding machine, the high-pressure airless polyurethane spray foaming machine has relatively high operating requirements. The following briefly introduces its operation process and precautions:
Before coating, it is necessary to prepare all necessary items for painting. The necessary items for painting include paint and thinner, paint agitator, weighing equipment, polyurethane spray foaming machine and supporting appliances, paint and coating Testing equipment, etc. In addition, the deployment of paint and machine debugging must be carried out.
The proportion of coating;
Confirm the paint: Confirm the type and quality of the paint according to the painting requirements, and correct the problem in time.
Adjust the viscosity of the paint: Stir the paint thoroughly and measure the viscosity of the paint. If the viscosity is too high, add a thinner to adjust the viscosity to a proper viscosity.
Installation and inspection of polyurethane spray foaming machine;
Installation: Correctly install and connect the parts and auxiliary accessories of the prepared polyurethane spray foaming machine.
Coating environment condition control: Measure the temperature and humidity of the spraying environment to meet the coating conditions, and the coating operation can be carried out. Outdoor painting should also consider weather factors. During a period of time from spraying to drying of the coating surface, rain and weather with high wind speed and heavy sand should be avoided.
Check: The polyurethane spray foaming machine is installed and connected and enters the state of waiting for spraying. Before spraying, check whether the power source is operating normally, and then suck in the paint, check whether the high-pressure paint cylinder is pressurized normally, whether the delivery hose is leaking, and the accessories are connected Whether it is tight, whether the spray gun and filter are blocked, etc. Find faults and eliminate them in time.

1. The formation of polyurethane foam needs to go through two stages of foaming and curing. From the beginning of the mixing of the black and white materials to the stop of the foam volume expansion, this process is called foaming. During the foaming process, the system releases a large amount of re
