Analysis on the technological performance of making color steel coils

The characteristics of color steel coils are excellent, but certain problems may also occur under special conditions. For example, the paint explosion of color steel coils is a common problem, so all problems often have its reasons and principles. This is due to the paint explosion problem on the roll.

Add passivating agent first, and then drain water when matching the tank. Because the relative density of the passivation agent is difficult, when the relative density of the passivation agent is higher than water, the raw materials will be mixed unevenly, and the adhesion between the passivation treatment layer and the substrate will not be very good, which is easy to make the surface layer of the color steel coil. There was a problem of paint explosion.

There is also a requirement for the production process flow of the passivation treatment plate temperature to be inspected multiple times. That is to say, the staff did not perform regular tracking of the passivation treatment plate temperature at the time of the inspection. Especially in the winter, the temperature change is relatively large, which will eventually lead to the timeliness of the colored steel coil, and the problem of scratching and peeling of the paint will occur at the time of pressing.

During the entire production process of color steel coils, the export value inspection mirror is covered with dust, and some rollers are also dusty. The dust will immediately harm the process performance of color steel coils. Perhaps the main performance is not displayed at the beginning, but If it takes a long time or is exposed to the sun, the paint will burst.

Because of the paint explosion problem of color steel coils, I firmly believe that you must learn at least the same professional knowledge as net editing. Generally speaking, the raw materials for color steel coils on the market at this stage are cold-rolled sheets and hot-dip galvanized sheets. Sheets, phosphating sheets and hot-dip galvanized sheets. In addition, this is this kind of colorful coated steel chain, which contains hot-dip galvanized steel chain as a plate.
