 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 ℃.
