What are the quality requirements for color coated plates in the process of processing
Physical property is the key index value to consider formability and the key parameter to determine and adjust manufacturing process. Therefore, physical property should be considered first in production and processing. Pencil hardness, T-bend, impact
energy and other index values are closely related to the production and processing characteristics, so they should also be considered. When the appearance of parts is complex and the deformation degree is large, multi pass forming should be selected.
If it is formed many times, it will cause excessive deformation and destroy the total iron binding force between the coating and the substrate.
In the process of production and processing, the appropriate gap should be set according to the appearance,
deformation characteristics, processing technology standards and other factors, and the coating thickness should be considered when setting the gap. Most coatings can be used as solid lubricants, and the wetting law of most forming processes can be considered.
Some architectural coatings can improve the wettability of coatings according to the adjustment secret recipe. If the wettability of the coating is not enough, the wettability can be improved by applying oil, wax and coating film, and the coating can
be separated from the original membrane. However, special attention shall be paid to the fact that the wet synovial fluid is easy to absorb waste, and the removable original membrane shall be removed before installation as soon as possible after the completion
of the project construction.
The effective production and processing speed should be determined according to the condition of the machine and equipment, the processing technology standard, the appearance of the parts, etc. the high-speed change
rate is easy to cause the coating to fall off. When the temperature is low, the flexibility of the coating is reduced, and the ultra-low temperature production and processing should be prevented. If the working temperature is low, the raw materials shall
be heated to the required temperature before production and processing.
