Some misunderstandings in the use of atomic ash

In the process of using the atomic ash, we need to pay attention to many things, to avoid the 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 ℃.

In the mid-1990s, under the great temptation of market interests, the manufacturers of atomic ash have been one by one, with large scale and small scale, and the products produced are also mixed. Therefore, the selection of high-quality atomic ash is also an important factor to ensure the construction quality, and the products of large-scale manufacturers should be selected as much as possible. 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.

Do not pursue fast hardening speed in use. In order to save time, it is a common problem for all users to require the atomic ash to harden as fast as possible. People always require the atomic ash manufacturers to produce fast curing products, or to add more curing agents to improve the curing speed. It is unscientific to do so, because the fast curing atomic ash may start the cross-linking reaction at the time of scraping, at the same time, the rapid hardening also reduces the corrosion inhibition of the 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 also have a variety of adverse effects on the film. Therefore, too fast hardening rate is an important factor that may reduce the adhesion of atomic ash.
