很多钢铁零件需要涂漆保护、装饰,为提高零件的抗蚀性、延长使用寿命,在涂漆前需要进行磷化处理。但目前常用的是热磷化,对操作者的身体健康有一定影响,而且设备比较复杂(必须有通风及加热设备),有一定的局限性。我厂以往用镀锌代替磷化,这样虽可提高零件的抗蚀性能,但漆层与镀层的结合力很差,成本较高。为了提高产品质量、提高
Many steel parts need paint protection, decoration, in order to improve the corrosion resistance of parts and prolong the service life, need phosphate coating before painting. However, the commonly used is the thermal phosphating, the operator’s health has a certain impact, and the equipment is more complex (there must be ventilation and heating equipment), there are some limitations. In the past, our factory used zinc instead of phosphating, though this could improve the corrosion resistance of the parts, the combination of paint and coating was poor and the cost was high. In order to improve product quality, improve
