Problem 1: Unstable coating quality

Unstable coating quality may be manifested as uneven color and inconsistent coating thickness. This may be caused by poor performance of the coating, improper setting of spraying equipment parameters, and inappropriate workshop environmental conditions.


Solutions include selecting coatings with good fluidity, adjusting spraying equipment parameters to ensure uniform spraying, and adding a constant temperature and humidity system to improve the workshop environment.

Problem 3: Pollution from coating production line emissions

The waste gas and wastewater emissions from coating production lines may have a negative impact on the environment, such as excessive volatile organic compound (VOC) emissions. This may be caused by spraying equipment that does not meet environmental protection requirements, improper operation, etc.


Solutions include using low-VOC paint to reduce environmental pressure, installing appropriate waste gas treatment equipment to meet emission standards, standardizing operating procedures to improve product qualification rate and reduce costs, etc.
