Aluminum in one of today's society is often used in construction material, its corrosion-resistant properties of polyurea spray stream processing, concise and elegant appearance, receive the public's favorite. Then, as the industry is concerned, the use of aluminum materials need to be sprayed before processing, then the aluminum coating process that is required before the process several processes, then sand Dongguan Hung spray processing of small series here today and we discuss about: the construction of metal spraying aluminum windows and curtain wall profiles today the primary structural material, widely used around the world. Aluminum Finish kneading without the appearance of a single profile, and briefly corrosion in humid air, making it difficult to meet the needs of construction and decoration materials high corrosion resistance. In order to advance the role of decoration, enhanced corrosion resistance and extend the use of life expectancy Changping polyurea spray processing, aluminum generally have a surface treatment. Aluminum organic coating due to having excellent surface quality, soft texture Tangxia polyurea spray processing, beautiful rich color, anti-corrosion and weather resistance and good benefits and get a lot of use of polyurea spray processing, the aluminum surface treatment about 35% of these years in the country to expand rapidly. Based on our practical experience in the construction process, we should focus on a few key points to grasp this: First, the extent of sand and sand, iron ore or corundum should be used, do not use quartz sand or river sand, sand level to reach M or C grade, or can not reach a high contact strength, would constitute a situation falling coating. Second, the sealing agent sealing skills, be sure to use good permeability, and the ability of data for high-temperature corrosion-resistant sealing agent, or can not reach the closed pores effect. Third, the uniformity and thickness of the coating, if there is no substantial construction experience, uniformity and thickness of the coating is difficult to ensure that the role of ambitions will be difficult to reach.
