Nowadays, aluminum guardrails are widely used and welcomed by users. Everyone knows that this device requires spraying, but do you know why?
1. The higher the purity of aluminum guardrails, the better their corrosion resistance. This is mainly because pure aluminum reacts with oxygen in the air, producing a very thin and dense natural oxide film on the surface of the aluminum, which is much faster and thicker than other metal oxide films, thus preventing further corrosion by harmful gases and moisture in the air and protecting it from the effects of action.
2. High mechanical strength, but low corrosion resistance. Although pure aluminum has good corrosion resistance, its mechanical strength is poor, which to some extent restricts its application. Therefore, people add appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make various types, greatly improving the mechanical strength of aluminum and expanding its application range. But its corrosion resistance is inferior to pure aluminum, so it may be oxidized and corroded. This requires powder coating of aluminum guardrails.
Through the above introduction of "Why is spraying work necessary for aluminum guardrails", this equipment has the characteristics of reasonable structure, simple design, and good anti-corrosion performance. However, it is also important to understand its spraying work. We hope this introduction will be helpful to you.
