With the rapid development of science and technology, the pace of people's work and life is faster and faster, and the requirements for work efficiency are higher and higher. A car just entered the repair shop immediately wants to repair it and drive away. In this way, the automobile sheet metal repair industry has entered a misunderstanding: the pursuit of too fast construction speed causes many adverse consequences, which leads to the occurrence of blistering and falling off of the atomic ash embedded in the body of some repaired vehicles. There are many reasons for these phenomena, but there are only the following:
1. Attention should be paid to the bottom treatment. The cleanliness of the repaired parts directly affects the adhesion between the atomic ash and the body metal. The repaired parts shall be polished with abrasive cloth to remove rust, old paint and surface dirt that cannot be removed by solvent cleaning, and then degreased with sina water to wipe the dust and oil on the surface. The construction shall be started immediately after the water evaporates to dryness, so as to prevent the repaired surface from being exposed to the air for a long time and being polluted again.
2. Avoid local overheating of the atomic ash coating. Because the construction environment temperature is too low or the customer's requirements are urgent, many construction personnel use ultraviolet lamp auxiliary heating and other methods to improve the drying speed of atomic ash, so as to shorten the construction period. It is not too bad to do so, but we must pay attention to the local overheating phenomenon. Because the insoluble and immiscible material after the hardening of atomic ash is a bad conductor of heat, the local high temperature will change the expansion coefficient and internal structure of the coating, resulting in foaming and other adverse consequences. It has been proved that the baking temperature should not exceed 80 ℃.
There are many factors that cause the bad effect of atomic ash, but most of them may be caused by improper operation, and the other part may be caused by the quality problem of atomic ash itself. Therefore, any substance has its limitations, which can not be done arbitrarily. The key to solve the problem is to select high-quality products and use them correctly.
