粉末喷涂可有效地延长工业铝板的使用寿命
　　Powder spraying can effectively prolong the service life of industrial aluminium sheets
　　从工艺本身来看，具有相当高的科技成分，调配颜色各异的涂料，产生不同色系的装饰效果，更加符合室内装饰的需要，也是与工业铝板在建筑业的应用向室内发展的趋势相一致的。特别是喷涂型材与隔热断桥的联合使用，使其更具有更时尚的潮流，使粉末喷涂型材具有了更大的发展空间，也是其他处理方式生产出来的型材所无法替代的。
　　From the point of view of technology itself, it has quite high scientific and technological components, dispensing paints with different colors, producing decorative effects of different color systems, which is more in line with the needs of interior decoration, and is also consistent with the trend of industrial aluminium sheet application in the construction industry to interior development. Especially the joint use of sprayed profiles and thermal insulation bridges makes it more fashionable, and makes powder sprayed profiles have greater development space, which is also irreplaceable by profiles produced by other processing methods.
　　目前常应用于三面翻广告中的粉末涂料为耐候性聚酯粉末涂料，粉末涂料用的聚酯树脂大多数为饱和型的，通常我们按其端基的结构可分为端羧基和端羟基两大类。当铝板用粉末喷涂再结合热转印技术，使其更具有更时尚的潮流，使粉末喷涂型材具有了更大的发展空间。
　　At present, the powder coatings commonly used in three-sided advertisements are weather-resistant polyester powder coatings. Most of the polyester resins used in powder coatings are saturated. Usually, according to the structure of their end groups, they can be divided into two categories: carboxyl-terminated and hydroxyl-terminated. When powder spraying combined with thermal transfer technology is used for aluminium sheet, it will become more fashionable and have more development space for powder spraying profiles.

                               
　　粉末涂料喷涂其工艺较为简单，成品率高，一般情况下，如果各项措施得当，可较大限度地控制不合格品的产生;能耗明显降低，在普通的阳极氧化、电泳涂装的生产过程中，水、电的消耗是相当大的，工业铝板加工特别是在氧化工序。其对水、大气的污染程度降低，片碱、硫酸及其它液体有机溶剂的不再使用，减少水及大气污染，也有效地提高铝板与作为环保产品的塑钢型材的竞争实力，相应地减少了一些生产成本;工人的劳动强度明显降低，由于采用自动化流水线作业，工业铝板上料方式以及夹具的使用方式已经得到明显简化，提高了生产效率，也降低了劳动强度;对毛料的表面质量要求标准有明显降低，提高铝板成品的表面质量;、铝板涂膜的一些物理指标较其他表面处理膜有明显提高，如硬度、三面翻广告、耐磨性、耐酸性，可有效地延长工业铝板的使用寿命。
　　Powder coating spraying process is relatively simple, high yield, in general, if appropriate measures, can maximize the control of the production of substandard products; energy consumption is significantly reduced, in the ordinary process of anodic oxidation, electrophoretic coating production, water and electricity consumption is quite large, industrial aluminum plate processing, especially in the oxidation process. Its pollution degree to water and air is reduced, the use of tablet alkali, sulfuric acid and other liquid organic solvents is no longer used, and the pollution of water and air is reduced. It also effectively improves the competitiveness of aluminium sheet and plastic steel profiles as environmental protection products, and accordingly reduces some production costs. The labor intensity of workers is significantly reduced, due to the use of automated assembly line operation, the way of industrial aluminium sheet material and the use of industrial aluminium sheet material. The use of fixture has been obviously simplified, the production efficiency has been improved, and the labor intensity has also been reduced; the surface quality standard of wool material has been significantly reduced, and the surface quality of finished aluminium sheet products has been improved; and some physical indexes of aluminium sheet coating have been significantly improved compared with other surface treatment films, such as hardness, three-sided advertisement, wear resistance and acid resistance, which can effectively prolong industrial aluminium sheet. Service life.
