Engineering machinery is an important part of the equipment industry. Engineering machinery can be seen in major areas related to national livelihood, such as national defense construction, transportation construction, industrial construction and production, mining, as well as production, water conservancy construction, construction, urban construction, and environmental protection.
In the “13th Five-Year Plan for the Prevention and Control of Volatile Organic Compound Pollution”, the engineering machinery manufacturing industry is also listed as a key target for rectification, and its transformation goals and paths are very clear: promote the use of powder and high-solid coatings; actively adopt advanced coating technologies such as robot spraying and electrostatic spraying, and the organic waste gas collection rate is not less than 80%.
Standard engineering machinery powder coatings have the following advantages over engineering machinery solvent-based coatings:
(1) The powder coating rate is good and can be recycled, with high coating utilization rate;
(2) The thickness of a single spray can reach 50-300μm, which is equivalent to the thickness of several or even dozens of layers of solvent-based and water-based coatings, which can significantly reduce the number of spraying times and improve production efficiency;
(3) Powder coatings are easy to apply, and do not require high spraying skills from workers, and are easy to master, while solvent-based and water-based coatings have high requirements for workers and the construction environment.
Therefore, engineering machinery powder coatings have great advantages over solvent-based coatings.
