Color-coated aluminum coils are widely used in many fields and industries. Its production management technology is also more complicated and strict, especially in coating. If you want to ensure its coating effect, you must be able to effectively ensure the following aspects Meet certain requirements.
1. Raw materials
Coatings and aluminum coils are the factors that can affect the coating quality the most during the coating process. Due to the color difference between the batches of the coating, the coating fineness is not enough and the coating rate is not high, the coating and the solvent are not well matched, and the layering will be directly Affect the coating effect, therefore, the selection of raw materials should be strictly controlled.
2. Equipment
The coating line requires to check whether the coating technology and equipment are intact. The management of coating equipment requires that the equipment runs smoothly without horizontal and vertical jitter. The coating roller requires fine grinding. All roll coating lateral runout must be controlled within the allowable range, otherwise it will seriously affect the quality of the coating surface.
3. Process
The coating production process has a close relationship with the quality management of coating, and requires that the relative linear speed ratio of the coating roller, paint roller, metering roller and substrate must be controlled within a certain range. According to different thickness coating products and systems, the coating is set to the normal range of viscosity to ensure the smooth progress of coating and promote the improvement of product quality.
