烟台电镀电泳漆涂层的盐雾试验标准及试验方法 2. Yantai electroplating : salt spray test standards and test methods for electrophoretic paint coatings

:如今,汽车已经成为了人们出行最重要的一种交通输工具之一。 Yantai electroplating : Today, cars have become one of the most important transportation tools for people to travel. Car painting is one of the four major processes of vehicle manufacturing, which can mainly play the role of anticorrosion and decoration. At present, almost all of the automotive industry uses electrophoretic paint as a primer, because automobiles are generally used in various corrosive environments, and automotive coatings need to have good corrosion resistance.

According to relevant experiments, what is the corrosion resistance of the coating? It can be judged by simulation test. By simulating the harsh atmospheric environment in which the car is located, and performing relevant tests on components with different film thicknesses, different parts and different structures, we can know its corrosion resistance and effectively take measures to improve the anti-corrosion ability of the entire vehicle. Among these test methods, the salt spray test is the most commonly used method. The following is the introduction of salt spray test methods for electrophoretic paint coatings by Feiyang professionals of electrophoretic paint manufacturers:

涂层的盐雾试验标准: Salt spray test standards for electrophoretic paint coatings:

In general, the evaluation standards should be proposed according to industry standards, and according to their own conditions, corresponding enterprise standards should be formulated for specific products in different parts and structures, and the coating department of automobile companies will generally have clear regulations on this. Automobile parts are very diverse and their uses are different, so the requirements for corrosion resistance are also different. For example, the corrosion resistance requirements of chassis components are much higher than those of seat components.

For the selection of electrophoretic paints, it is generally required that the corrosion resistance of the electrophoretic paints is reached: resistance to neutral salt spray test for 1000 hours.

Conventional salt spray test methods for electrophoretic paint coatings:

、对样板的周边作包边或者进行封蜡,于待检部分用价刀划叉。 1. Edge the perimeter of the template or seal wax, and use a valance knife to cross the part to be inspected. Note: the coating must be penetrated to the substrate;
、将样件放到盐雾试验机的喷雾箱内。 2. Put the sample in the spray box of the salt spray tester. Note: The placement angle is generally about 45 degrees, and there must be no objects above to prevent the salt fog from falling.
、喷雾盐水浓度为5%,盐雾试验箱内温度为35度。 3. The concentration of spray salt water is 5%, and the temperature in the salt spray test chamber is 35 degrees.
、试验中止时间:刻划线单侧扩蚀达到2mm时。 4. Test suspension time: when the engraved etch on one side reaches 2mm.

Note: The salt spray test methods for electrophoretic paint coatings are generally-neutral salt spray test, acetate salt spray test and copper sulfate accelerated salt spray test. However, in general, the salt spray test method that we often say mainly refers to the neutral salt spray test.
