What should be paid attention to in the use of automobile atomic ash to avoid local overheating of atomic ash coating. Because the construction environment temperature is too low or the customer's requirements are very urgent, many construction personnel use ultraviolet lamp to assist in heating and other methods to improve the drying speed of atomic ash, so as to shorten the construction period. This is not impossible, but we must pay attention to local overheating. Since the insoluble and immiscible substance after hardening of atomic ash is a poor conductor of heat, local excessive temperature will change the expansion coefficient and internal structure of the coating, resulting in foaming and other adverse consequences. The test shows that the general baking temperature should not exceed 80 ℃.

In the mid-1990s, due to the great temptation of market interests, the atomic ash manufacturers were all different, with different scales, and the products produced were mixed. Therefore, the selection of excellent atomic ash is also an important factor to ensure the construction quality, and the products of manufacturers with large production scale should be selected as far as possible. There are many factors that may cause adverse effects after the use of atomic ash, but the vast majority may be caused by improper operation, and the other part may be caused by the quality problems of atomic ash itself. Therefore, any substance has its limitations and cannot be used arbitrarily. The key to solving the problem is to select excellent products and use them correctly.

Do not pursue a faster hardening speed during use. In order to save time, it is a common problem for all users to require that the faster the atomic ash hardens, the better. People always require Yunnan atomic ash manufacturers to produce fast curing products, or add more curing agents to improve the curing speed. This is unscientific, because the rapid curing atomic ash may start the cross-linking reaction during scraping, and the rapid hardening also reduces the corrosion inhibition of atomic ash on the metal and reduces the adhesion. In addition, adding more curing agent can not improve the hardening speed, and the compound will have a variety of adverse effects on the film.
