Galvanized iron wire manufacturers anti-rust knowledge
The main factors causing metal rust:

Atmospheric relative humidity At the same temperature, the percentage of water vapor content and water vapor saturation in the atmosphere is called relative humidity. At a certain relative humidity, the corrosion rate of the metal anti-rust oil is small, but higher than the relative humidity, the corrosion rate suddenly increases.

This relative humidity is called critical humidity. Many metals have a critical humidity between 50% and 80%, while steel has a critical humidity of around 75%. Atmospheric relative humidity has the greatest impact on metal corrosion. When the humidity in the atmosphere is higher than the critical humidity, water film or water droplets may appear on the metal surface. If the atmosphere contains harmful impurities, it dissolves in water film, water droplets, electrolytes and exacerbates corrosion.

Among the hardware products produced by Galvanized iron wire manufacturers, the main problem in the storage work is to prevent corrosion. Metal corrosion is caused by chemical or electrochemical action of the surrounding medium. According to different media, it is divided into atmospheric corrosion, soil corrosion, seawater corrosion, and bacterial corrosion. Atmospheric corrosion is the most common because metal products are in contact with the atmosphere during processing, transportation, and storage, and there are always atmospheric corrosion conditions.
In the habitual metal in the atmosphere due to corrosion or discoloration caused by oxygen, water and other impurities, it is called rust or corrosion. Rusty metal products, light affect the appearance quality, seriously affect the use, and even lead to useless, so the metal products in the custody must be properly kept, pay attention to rust prevention.

The company has always adhered to the corporate philosophy of "survive by quality, develop by reputation, market-oriented, and benefit from management". It has won scientific management, advanced equipment, strict process and strong dedication. The trust and praise of the majority of users.
