Modern countries pay attention to energy conservation and environmental protection. Some energy conservation and environmental protection policies have also been introduced in our country. With the wide application and development of light radiators in China, the requirements for anticorrosive coatings in radiators are getting higher and higher. Scientific selection of high-quality internal anti-corrosion coatings is the key to the service life of radiator products.
Coating anti-corrosion is currently the most widely used, most economical and most practical means.
First, scientifically choose anti-corrosion coatings. At present, there are no more than ten kinds of anti-corrosion coatings used in the radiator industry, and the quality varies greatly. Inevitably, there is a phenomenon of “fishing mixed with beadsâ€. Therefore, when selecting coatings, it is necessary to select those that have been applied in practice for a long time, good reputation, especially It is a coating product used by some large radiator manufacturers.
Second, strictly control the quality of pre-treatment. There is a saying in the coating industry called “three-part paint, seven-point paintâ€, and in the painting, the pre-treatment quality is very important and has a very important position. According to the data, the pre-treatment quality has a high influence on the coating quality. More than 50%, the quality of the pre-treatment is not good, just like the high-rise buildings built on the desert, it is difficult to obtain high-quality coating. In order to do pre-treatment, in addition to the quality of the pre-treated materials, is it strictly controlled according to the process requirements provided by the pre-treatment material supplier? The temperature and the effective components of the bath are critical. In addition, due to the radiator products The particularity of the structure, whether the washing in each pretreatment process is guaranteed to be clean should also attract sufficient attention.
Third, pay attention to the treatment of heating radiators in the production process such as cutting, drilling is the formation of flash, burrs and welding slag generated during welding, otherwise, in the painting process, these parts are difficult to form a complete coating, will It is a fatal hazard to the anti-corrosion of the radiator.
