The purpose of using air filters for air cleaning during coating operations is to focus on the selection, maintenance, and installation guidelines of filtering systems in ventilation systems. Analyze the advantages and disadvantages of reusing air filters.
It is well known to use the coating method for the surface decoration of products, but it is difficult to imagine the high requirements for the coating quality of various products today. For example, in daily use of mobile phones, personal computer shells, and even small cosmetics containers, it is difficult to observe the gray particles and flaws on the product surface. The surface coating of domestic car bodies requires only 2 particles in the most obvious parts. The coating quality of engineering plastic exterior trims for cars, including front and rear bumpers of cars, and door protection panels, must also achieve the same appearance. It is reported that Germany The Volkswagen MOSEL plant requires that the surface finish of the car body be around 4 particles. In response to such high requirements, with the development of coating materials, the innovation of coating equipment and the gradual improvement of construction technology, mechanized and automated coating production lines have become increasingly mature and widely adopted, and can be satisfactorily resolved. However, one of the key technologies must be mentioned. It is precisely because of it that it can play the role of ensuring the high decoration of the product's surface coating. This is the technology of using air filters to clean the air in the coating environment because The ash particles suspended in the air will affect the quality of the coating, and seriously cause the loss of human, material and financial resources.
Sources of dust and ash:
In addition to the quality factors of the coating material itself, the dust and ash particles in the coating operation are also suspended in the coating environment; the ash particles accumulated in the ventilation ducts; in the spray booth, drying room, drying Ash particles adhering to the surface of the chamber and the conveying device fly down on the wet paint film or other coating surface; dust brought by the operator and scattering of clothing fabric fibers are killers that affect the quality of the coating. Therefore, it is necessary to raise the awareness of cleanliness of the working environment for all employees, and to recognize that the impact of ash particles must not be ignored in every step of the coating process and eliminated. Only in this way can we always maintain the high quality of the coating and the efficient operation of the production process. How to prevent the dust particles in the coating environment is the key to the quality of the coating.
