Tips for Preventing Corrosion in Hardware Tools

Anti-corrosion protection is the main issue when metal products are stored in hardware products. The environment can cause corrosion of metals. We have now a lot of common sense regarding hardware rust protection.

Tips for Preventing Corrosion in Hardware Tools Metal rust is caused by several factors.

1. Atmospheric relative humidity: 

At the same temperature the proportion of water vapor in air and total water vapor are called relative humidity. The metal corrosion rate below a certain level of relative humidity is extremely low. Above this, the corrosion rate rises dramatically. This is known as critical humidity. Many metals have a critical moisture content between 50 and 80%. Steel has a critical moisture content around 75%. The greatest influence on corrosion of metals is the relative humidity. The metal surface will be affected if the humidity of the air is higher than the critical humidity. The soil water film and water dropslets can be disintegrated by harmful impurities in the air, which can lead to electrolyte formation, which can worsen corrosion.

2. Metal corrosion is associated with temperature and humidity. 

These conditions are simple: First, increasing temperatures cause water vapor to increase in the atmosphere. Second, high temperatures promote corrosion. In a humid environment, corrosion rates will accelerate faster with higher temperatures. Low relative humidity has negligible effects on corrosion. However, when relative humidity is high, it can cause severe corrosion. Water condensation can also form on the metal's surface if the temperature is different between the metal and the atmosphere. This will cause it to rust.

3.Corrosive gas: 

Of all the corrosive substances in polluted atmosphere, sulfur dioxide has the most impact on the corrosion and rusting of metals. This is especially true for steel, copper, and their alloys. The main source of sulfur dioxide in the atmosphere is from burning coal. However, carbon dioxide from combustion can also have a corrosive impact. Corrosive gases can mix with the air around the plant. Hydrochloric acid and ammonia are all factors that can cause metal corrosion. Metal corrosion is caused by these factors.

Principles for the storage of hardware products 1. Choose a suitable storage location Metal materials must be stored dry and clean inside and out. Avoid dust and harmful gases from being generated on factory floors. Magnesium alloys and small-sized steel products, as well as steel strips, sheets, and thin steel sheets, should all be kept in warehouses. If conditions allow, special warehouses may be used. 2. Keep sklhell dry Keep the warehouse's relative humidity below the critical humidity. The relative humidity in a warehouse should not exceed 70%. You should manage warehouse temperature and humidity. Respond to any weather change, avoid hurricanes or heavy rains, and use ventilation to lower temperatures and tides. Hot flashes can be reduced by placing a desiccant inside the library. To prevent or reduce corrosion, it is important to keep the warehouse dry. 3. Proper packaging, matting and sealing Proper palletizing is an important link in hardware to protect from moisture and damage. Palletizing should be consistent, reasonable, durable, quantifiable, regular, and compact. The seal protects the metal material from outside air and reduces corrosion. 4. Rust prevention oil injection Metal parts that are stored outside in hot and humid areas of the south will not be protected from rust if they are not covered with straw. It takes time to build steel rods, cold-rolled and cold drawn steel materials. This method is not recommended for those who aren't suitable for fuel injection. 5. Keep the packaging and protective layer intact Anti-corrosion treatment is used to prevent metal products from rusting. This includes chemical treatment to form a protective layer, anti-corrosion coating, and anti-corrosion packaging. It is important to protect the anti-corrosion outer layers and packaging from damage during transportation, loading, unloading, storage. Damaged packaging should be replaced or repaired. Those affected by moisture should also be dried. Those coated with antirust oil should be removed and relubricated.
