钣金加工后的产品应该怎样防锈防腐？

钣金加工后的产品应该怎样防腐？因为金属产品是暴露在空气中的金属，而经过钣金加工后的产品更加需要做好防腐的措施，因为在加工过程中添加了其他的成分，充当了电解质，金属空气的水分很容易发生氧化的效果，那么金属钣金加工后应该如何去处理呢？

步骤一：钣金加工产品基层除锈处理。

步骤二：钣金加工产品做环氧富锌底漆，主要用于钢结构和钢铁制品的防锈底漆，其涂膜具有良好的理化性能，易于施工，配套性能较好。主要成分为：环氧树脂，环氧固化剂，锌粉，防锈颜料，助剂和机溶剂等。

步骤三：钣金加工产品做环氧云铁中间漆：与环氧富锌底漆配套使用，作长效防腐涂层过渡层，其作用为增强复合涂层的封闭性和防腐性，也可用作防腐防锈底漆。涂膜强韧，具有良好的附着力和封闭性，与前后道涂层配套性良好。其成分为：环氧树脂及固化剂，运母氧化铁及防锈颜料等。

步骤四：钣金加工产品做面层。其面层可用于环氧沥青面漆，氯化橡胶面漆，丙烯酸及聚氨酯面漆，氟碳面漆等。

How should the product after sheet metal process be anticorrosion? Because the metal product is exposed to the air after metal, sheet metal processing products after more need to do anti-corrosion measures, due to the addition of other ingredients in the process, as the metal electrolyte, the moisture of the air is prone to oxidation effect, then the sheet metal processing should be how to deal with it?

Step one: rust removing treatment of sheet metal processing products.

Step two: the product of sheet metal processing is made of epoxy zinc rich primer, which is mainly used for antirust primer of steel structure and steel products. The coating has good physical and chemical properties, easy construction and good supporting performance. The main components are epoxy resin, epoxy curing agent, zinc powder, rust preventive pigment, auxiliaries and machine solvents.

Step three: sheet metal processing products made of epoxy cloud and iron intermediate paint: used with epoxy zinc rich primer for long effect anticorrosion coating, the effect is to enhance the sealing and anticorrosion of the composite coating, and can also be used as anticorrosive and antirust primer. The coating is strong and tough, with good adhesion and sealing property, and good compatibility with the front and rear coating. Its components are epoxy resin and curing agent, ferric oxide and rust preventive pigments.

Step four: the sheet metal processing product to make the surface layer. It can be used for epoxy asphalt finish, chlorinated rubber finish, acrylic and polyurethane topcoat, fluorocarbon finish, etc.
