五金涂裝線前處理線—棚體前處理、棚體前處理線、噴涂前處理線

五金涂裝線前處理線—棚體前處理：工件表面有氧化皮、油脂、灰塵等污垢物，如果在涂裝前不把這些異物去除，將影響涂膜固化或造成涂層龜裂、剝落，尤其是殘留的氧化還會在涂層下繼紐生長而失去涂裝意義，因此，涂裝前處理的目的就是去除金屬表面附著的各種污垢物，以提高金屬與涂膜的結(jié)合牢固、附著力強(qiáng)、從而使產(chǎn)品獲得高品質(zhì)、延長產(chǎn)品的使用壽命，從而保護(hù)金屬不受腐蝕破壞。

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.
