1.The material flows behind the wall：
Reason: The material speed is slow, or the material atomization is not good, and the spraying is uneven.
Solution: Adjust the equipment, increase the heating temperature of the pipeline, and improve the heating capacity of the equipment.
2.Uneven foam surface：
Reason: The speed of the material is not coordinated, the nozzle is deformed, and the coating is too thick at a time.
Solution: Adjust the equipment, clean up the material residues in the nozzle, and increase the air source pressure.
3.The material is not out of the square and the price is low：
Reasons: The on-site environment is harsh, the ambient temperature is low, the wind speed is large, and the equipment is blackened. Many reasons can cause the phenomenon of low output.
Solution: Increase the temperature of the material, while shielding the window parts to reduce losses, and reduce construction in windy weather.
4.The material is not well bonded：
Cause: The substrate is polluted by dust and the temperature of the base layer is low.
Solution: Purify the substrate to increase the temperature of the base layer.
5.Block the gun：
Reason: The white material has impurities or the black material enters the water and crystallizes, accompanied by a certain phenomenon of partial material.
Solution: Reduce the heating temperature of the equipment, and at the same time check whether the black and white material pipeline is clogged with impurities.
