At present, there are many functional color coated steel plates, such as antibacterial color coating, antistatic color coating, heat insulation color coating, self cleaning color coating and so on. The development of these products is aimed at meeting the special needs of the users, but sometimes it can not take into account the other properties of color coated products, such as the self cleaning color coated steel plate in the present market. After the use in recent years, we find that the self cleaning color coated steel plate can not be effectively clean, and it can cause damage to the durability of the coating. Because at present the principle of self cleaning coating is to use the high hydrophilicity of the coating, even if there is ash on the steel plate, through the rain to penetrate the dust and take the dust away to achieve the purpose of self cleaning. Theoretically, the water penetration of the hydrophilic coating on the substrate will be relatively easy. Therefore, the corrosion resistance of the color coated steel plate is relatively low. In addition, we found that the contact angle of self cleaning performance of self cleaning color coated steel plate has been found to be less than half a year in outdoor exposure. The contact angle is not the same as that of ordinary polyester color coating. From this point of view, self cleaning self cleaning can only be maintained for about half a year. Our rainwater is sometimes not very clean. Sometimes it is not self-cleaning when it rains, but it leaves behind a dirty water line. Finally, there is also a point to explain that more and more wall panels are now using a cross plate structure, so that the theoretical effect of the self cleaning steel plate is not. Therefore, users must choose their functional color coated steel plates to clarify their real needs.
