Three air environmental factors for corrosion of door and window hardware
[China Glass Net] Although the aluminum alloy door and window hardware has strong anti-corrosion, but due to the influence of air, climate and other factors, it still poses a great threat to the aluminum door and window hardware. The air and environmental causes are mainly reflected in air humidity, ambient temperature, and air pollution.
1, air humidity
It is easy to understand that the aluminum alloy door and window hardware is exposed to the humid air for a long time, and the moisture in the air will be condensed into liquid water beads, thereby forming a corrosion original battery on the surface of the aluminum door and window hardware, accelerating the electrolytic corrosion of the door and window hardware. . Therefore, air humidity is the main cause. When the humidity reaches a certain critical value, there will be a water film type, so that the corrosion of the aluminum alloy door and window hardware is inevitable.
Therefore, it is especially important to keep the doors and windows dry and the indoor environment ventilated and dry. In case of hot and humid weather, keep a good ventilation and also diligently wipe to ensure that the doors and windows are dry.
2, temperature
In the hot and humid summer, as the temperature rises, the corrosion of the aluminum door and window hardware will be accelerated. At the same time, the temperature difference between day and night will be large, and a large amount of water will be condensed at night to further accelerate the corrosion process. When the damp time is too long, the corrosion of the aluminum door and window hardware becomes more serious. Generally speaking, when the temperature difference between day and night is greater than 6 °C and the temperature changes within the range of 5 °C to 50 °C, condensation will occur as long as the relative humidity reaches 65%-75%.
3. Air pollution
In recent years, environmental pollution has become increasingly serious, and the air is filled with PM2.5, sulfides, and corrosive media. Acid and alkaline substances will be adsorbed on the aluminum door and window hardware, which will cause acid and alkali corrosion to the hardware. At the same time, due to air pollution, acid rain frequently occurs, which is also a threat to aluminum door and window hardware. In addition to acid-base corrosion, carbon powder particles and metal powder in the air, which are adsorbed on the surface of the aluminum door and window, will also form a surge with the aluminum door and window hardware, causing electrolytic corrosion.
Therefore, the daily anti-corrosion work of aluminum door and window hardware, in addition to ensuring the cleanliness and dryness of doors and windows, also requires us to take care of the environment from ourselves.

Hematite meaning and properties
Hematite is used to improve relationships. If you need your personal relationship to be better, carry a hematite with you always.
The name comes from the Greek word for blood. It has been used as an amulet against bleeding, and so is known as the "blood stone". When arranged like the petals of a flower, it is referred to as the "iron rose". Native American folklore states that war paint made from hematite will make one invincible in battle. People in the eighteenth and nineteenth centuries wore hematite jewelry during mourning.
Scientists of the Mars Exploration Rover Project believe that deposits of hematite ono Mars .may help prove whether large amounts of liquid water ever flowed on Mars' surface. They say that where water was, life may have had a chance to thrive as well.Hematite is good for increasing intuition. In jewelry it is best in a ring worn on the left hand.
Healing properties of Hematite
Hematite stimulates iron absorption in the small intestine, which in turn improves oxygen supply to the body. It can be in direct contact with the skin, but results in inflammation for some people, so test it carefully on yourself before use.
Sources of Hematite
Brazil is the most important source of hematite. Other sources include: China, Canada, England, and Germany.
