As long as you pay attention to these points when using color coated products, you can reduce the possibility of fire. Don't ignore some details. Fire is likely to be caused by details. I believe that you pay attention to these problems. When using color coated products, it will be very safe and will not cause fire.
Compared with the building board, the substrate used in the color coating roll has higher elongation, yield ratio and corresponding r and n values; Moreover, the adhesion between the paint film and the substrate is strong, the coating has certain flexibility, and the corresponding hardness is low. When the color-coated steel coil for household appliances is cut and uncoiled, there is often a kind of defect on the surface - the surface pressure spot defect. This defect is the slight deformation of the coating surface caused by the coiling tension when the color-coated plate coating is baked and cooled, and sometimes the surface appears rough, showing the visible pressure spot shape. The slight indentation defect will gradually disappear with the extension of the storage time of the steel plate, and can also be eliminated after heating.
However, the relatively serious pressure spot defect cannot be eliminated even if the above measures are taken, thus affecting the use of users. Because the color coated roll is made of steel as raw material, it has an important relationship with the price of the national steel market. We all focus on stability. Up to now, the average price of the national steel market is flat compared with the price of the previous week. The price of the steel market for the color coated roll is also a continuous and stable phenomenon. The volume of the color coated roll is still relatively large, and the mentality of the merchants is now more cautious.
