Barbed wire will form a dense black oxide layer after heat treatment, the oxide layer must be clear and clean before silking. At present, most companies use hydrochloric acid pickling process.
Hydrochloric acid pickling has the advantages of fast pickling speed and low cost. At the same time, it also has the advantages of high temperature volatility, large corrosiveness, hydrogen embrittlement, easy silk rust, more water for rinsing, more water treatment sludge, and water treatment after water treatment. Can not be reused, anti-rust costs high disadvantages.
The use of environmentally friendly non-volatile weak acid pickling to replace hydrochloric acid has been successfully developed and used in wire processing. It has very obvious advantages.
Huaguang can manufacture wire mesh fences with other heights and length on request.
