轿车涂装技术的特点与工艺探讨.doc

摘 要 21世纪被称为面向环境的新世纪,环境保护倍受全球关注,并已成为人类最迫切的研究课题。汽车及其零部件的涂装是汽车制造过程中产生三废排放最多的环节之一,所以减少涂装公害、降低涂装成本、提高涂装质量一直是涂装技术发展的主题。, 其规划水平的高低直接影响轿车产品的外观质量、整车寿命，随着汽车市场竞争的日趋激烈以及环保呼声的日渐增高，汽车涂装在保证高装饰性、高防腐蚀性能的同时，对于环境保护的效果、涂装材料和涂装生产成本以及设备投资也越来越为重视。 汽车涂装工艺正朝着简化工序、减少设备投资、减少占地面积、提高生产效率、降低能源消耗、减少人员费用等方向发展。涂装材料 Abstract 21 century is called the new century for the environment, and the environmental protection highly global attention, and has become a humans most urgent research subject. Car and parts of the coating is in the process of producing cars produced one of the largest emitter three wastes link, so reduce pollution and reduce coating coating the cost and improve the quality of coating has been the development of coating technology theme. The coating process is car production special process, the planning level directly affect the appearance of the products quality, car vehicle life as the market competition becomes increasingly fierce and environmental protection are mounting up behind, car coating in the guarantee high ornamental, high corrosion resistance performance at the same time, for the protection of the environment effect, coating materials and coating production cost, the equipment investment is also more and more attention. Car.
