五金涂装线前处理线—棚体前处理、棚体前处理线、喷涂前处理线

五金涂装线前处理线—棚体前处理：工件表面有氧化皮、油脂、灰尘等污垢物，如果在涂装前不把这些异物去除，将影响涂膜固化或造成涂层龟裂、剥落，尤其是残留的氧化还会在涂层下继纽生长而失去涂装意义，因此，涂装前处理的目的就是去除金属表面附着的各种污垢物，以提高金属与涂膜的结合牢固、附着力强、从而使产品获得高品质、延长产品的使用寿命，从而保护金属不受腐蚀破坏。

Metal coating pretreatment line - tent devices for processing, shed a whole processing line, spraying pretreatment line

Metal coating line pretreatment line - shed a whole processing: the surface has a scale, grease, dirt and other contaminants, if not remove the foreign body before coating, will affect curing coating or coating crack, flake, especially the oxidation residue in coating under the new growth and lose coating, therefore, the purpose of the pretreatment is to remove the metal coating the surface of all kinds of dirt, in order to improve the combination of metal and coating is firm, strong adhesion, so that the products high quality, prolong the service life of the product, so as to protect the metal from corrosion damage.
