What Will Cause Bad Quality of Black Aluminum Strip
The color coated aluminum strip is widely used in ceiling, shutter, gutter, channel letter, lamp base,etc. Roller coating is an important process in the entire aluminum alloy coil strip painting production line. The quality of sprayed products, especially the quality of conductivity, will immediately affect the actual effect of product decoration. Therefore, it is necessary to analyze the main reasons for the decline in the quality of coated aluminum strips for sale.
1. Machinery
The mechanical equipment of the spraying production line should be in good condition. The mechanical equipment runs stably, there should be no horizontal or vertical tremors, and the spraying rollers are regularly and finely ground. All the operations should be according to the regulated rules, otherwise he performance of the coating process will be seriously damaged.
2. Surroundings
It is required that the spraying room should be tidy, anti-fouling, anti-moth and of certain natural ventilation condition, so as to ensure that the performance of the spraying process will not be polluted by the environment. In addition, due to the change of average temperature, the processing technology specification should be changed immediately.
3. Raw material
The coatings and aluminum coils are two important factors that will affect the spraying quality. The color difference may exist in different batches of the paintings. The Insufficient fusion of paint and organic solvent will damage the spraying effect and cause defects. The unevenness of the aluminum coil, uneven film thickness, and poor edge tensile strain will immediately affect the product quality and overall application. Therefore, strict control should be exercised when selecting raw materials.
4. Human error
The mastery of technology and the standardization of actual operation are the key to obtaining high quality spraying. Therefore, it is necessary to strengthen the learning and training of operators and allow operators to master the basic principles and details of spraying technology and carry out operations in strict accordance with safety operating procedures to ensure high-quality spraying products.
The painting process is closely related to the quality of the spraying. The color coated aluminum strip manufacturers should make adjustment according to different management systems and the film thickness of sprayed products. Haomei Aluminum has several mature coating and cutting production lines. In addition to the common colors like black aluminium strip, we can also customize according to the customers’ sample or color card.
