In the use of color coated roll, we usually hope that the quality and price of the products we buy are very suitable, and they are cost-effective products. For manufacturers, in order to produce good quality products, they should master more relevant
information, so as to pay attention to do more details when processing, so as to improve the quality and quality of color coated roll. Therefore, it is necessary to understand several aspects of the performance of color coated roll with good quality.
What are the main aspects of good quality of color coated roll
1、 Mechanical properties and related indexes
In the processing of color coated products, the mechanical properties should be taken as an important index to measure the formability
of the products, so we can check the situation in this aspect before processing and purchasing. At the same time, the pencil hardness, T-bend, impact energy and other indicators of the color coated roll are closely related to the processing performance,
so they should be fully considered.
2、 Processing technology
Due to the complex shape and large deformation of various color coated roll parts, it is necessary to adopt multi pass forming in processing technology. If it is directly formed
at one time, the adhesion between the coating and the substrate may be damaged due to excessive deformation. Therefore, appropriate clearance should be set according to the mold shape, deformation characteristics, process conditions and other factors
when processing the color coated coil, and the thickness of the coating should be considered when setting the gap.
3、 Lubrication performance
Most of the coatings can be used as solid lubricants and meet the lubrication requirements of most
forming processes. Some coatings can improve the lubricity of coatings by adjusting the formulation. If the lubricity of the color coated coil coating is insufficient, the lubricity can be improved by applying oil, waxing and
