How many ways do you know about metal surface treatment?

2018/5/9 10:32:36 Viewers:
The use of hardware tools in our life is very common, often involves the surface wear resistance, corrosion resistance function requirements, in order to improve the utilization of hardware products, it is very important to do the protection of the surface of the hardware. The subdivision of metal surface processing can be divided into: metal spray painting, electroplating, surface polishing, metal corrosion processing, alloy catalytic liquid and so on. How many ways do you know about metal surface treatment?


1, spray painting processing: at present, the hardware factory in the production of large pieces of hardware products when the use of paint processing, through the spray paint processing to avoid rusting hardware, such as: daily necessities, electrical housing, handicrafts and so on.


2, electroplating: electroplating is also the most common processing technology of hardware processing, through the modern technology technology to the metal surface electroplating, to ensure that the products are used for a long time without mouldy embroidery, electroplating processing is common: screws, stamping parts, battery pieces, car parts, small ornaments and so on.


3, surface polishing processing: the surface polishing process is generally used in daily necessities, through the surface burr treatment of hardware products, the edge corner sharp part is thrown into the smooth face, so that in the process of use, it will not cause harm to the human body.


4, alloy catalytic liquid technology: alloy catalytic liquid suitable for all kinds of metal materials, as long as the flow can be immersed in place to be catalyzed. The product can be processed at room temperature up to 83 degrees Celsius. In the process of processing, usually immerse in metal for about 15-20 minutes. After soaking, rinse thoroughly with clean water and use it naturally. Sealed under normal temperature and pressure for 3-5 years will not deteriorate. The application of alloy catalytic liquid is very wide. It has been applied in the fields of aviation industry, automobile industry, petrochemical industry, textile industry, hardware industry, mechanical equipment, electronic electrician, food, medicine and other fields.


In order to reduce the pollution of the traditional metal surface treatment process, the state is gradually reducing the use of the traditional metal surface treatment process, especially the promulgation of the new environmental protection law. The state has already banned the use of electroplating, the state is in the spirit of Scientific Outlook on Development, in order to reduce the pollution of the traditional metal surface treatment process. The metal surface treatment technology of green and environmental protection is being vigorously supported, and the use of the alloy catalyst solution effectively solves the pollution problem caused by the electroplating process. In 2016, it was one of the national key projects.


Alloy catalytic liquid is a low-cost, simple and clean environmental effect. It has the characteristics of tight plating and low porosity. Alloy catalytic plating is a standard cleaner production process. The so-called clean production means making liquid by using non polluting food as raw material to make production process. It can be plated with a variety of metal materials, iron, carbon steel, die steel, alloy steel, copper and copper alloy, aluminum and aluminum alloy, and so on. The coating has good uniformity and strong adhesion, wear-resisting and corrosion resistance.
