为什么要提供保护?
Why should we provide protection?
 
降低各种环境的腐蚀
Reduce the corrosion of all kinds of environment
 
改善耐磨性能-降低腐蚀产品的连接零件
Improve wear resistance - reduce the connection parts of corrosion products
 
缺乏恰当的维护
Lack of proper maintenance
 
润滑–脂和油
Lubrication - grease and oil
 
保护链条和提供良好的耐磨性能的比较低成本方法
The minimum cost method for protecting the chain and providing good wear resistance
 
优点:1、过程简单2、不减少断裂负荷3、低成本
Advantages: 1, the process is simple 2, does not reduce the breaking load 3, low cost
 
需谨慎的方面:1、定期润滑2、不适合酸或碱的环境
Prudent aspects: 1, regular lubrication 2, unsuitable for acid or alkali environment
 
锌-机械镀锌
Zinc mechanical zinc plating
 
在一个旋转的鼓形圆筒里面,通过锌粉和特殊玻璃珠撞击零件表面,机械地将锌粉固定在零件表面
In a rotating drum shaped cylinder, zinc powder and special glass bead are impacted on the surface of the part, and zinc powder is mechanically fixed to the surface of the part.
 
优点:1、过程简单2、不减少硬度或断裂负荷3、中等成本
Advantages: 1, the process is simple 2, no reduction of hardness or fracture load 3, medium cost
 
需谨慎的方面:1、低耐磨2、镀层不均匀,跟电镀相比,耐腐蚀性能更低
Prudent aspects: 1, low wear resistance 2, non uniform coating, lower corrosion resistance compared with electroplating
锌-电镀
Zinc electroplating
 
通过电耦作用产生的电解溶液来对零件镀锌,两步电镀涂层工艺来提高耐腐蚀和耐磨性能
Electrolytic solution produced by electrocoupling to galvanize parts and two steps electroplating coating process to improve corrosion resistance and wear resistance
 
优点:1、与镀锌相比,更高的机械和耐化学物质性能2、低毒性
Advantages: 1. Compared with galvanizing, higher mechanical and chemical resistance properties are 2 and low toxicity.
 
需谨慎的方面:1、镀层工艺会降低15%拉伸强度2、比镀锌的成本高
Caution is required: 1, the coating process will reduce the 15% tensile strength by 2, and the cost is higher than that of the galvanizing.
