After the barbecue net is processed and manufactured, it is generally required to stop the surface treatment, so that the product has the characteristics of beauty, rust prevention and corrosion prevention. Generally speaking, there are two ways to treat the surface of barbecue net, galvanizing and polishing. Here we will introduce these two processes: galvanizing, that is, cold plating, which is galvanizing on the surface of barbecue net by electroplating.

The main process is to immerse the barbecue net and zinc block in the electrolyte at the same time, separate the positive and negative poles passing through the direct current, the average coating of waste products, the surface of the barbecue net galvanized in the acid electrolyte is brighter, the surface of the barbecue net galvanized in the alkaline electrolyte is whiter, but there is no difference between the two qualities. The process is mainly used for the surface treatment of low carbon steel wire (iron wire) barbecue net.

As for the stainless steel barbecue net products, the commonly used surface treatment method is polishing. There are three polishing methods: mechanical polishing, chemical polishing and electrochemical polishing. Each of these three methods has its own advantages and disadvantages. The mechanical polishing of stainless steel barbecue net has high brightness. Its disadvantages are high labor intensity, severe pollution, and its luster can not be inconsistent, the duration of gloss is not long, stuffy and rusty.

Compared with the simple products, medium and small products, chemical polishing has the advantages of less investment in processing equipment, polishing, high speed, high efficiency and good corrosion resistance. Its disadvantage is poor brightness, gas overflow, need ventilation equipment, heating difficult. This kind of screen deep processing product is suitable for processing small batch of complex parts and products with low light intensity of small parts.
