[China Aluminum Industry Network] Aluminum profiles are widely used in buildings, doors, windows, curtain walls and other products for many years due to their small specific gravity, easy processing, and large mechanical strength. Aluminum is a more active light metal with silvery white luster, and its corrosion resistance has the following two characteristics:
The higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air, producing a thin and dense natural oxide film on the aluminum surface, which is faster and thicker than other metal oxide films. , Which prevents further corrosion of harmful gases and moisture in the air and plays a protective role;
Aluminum profiles have high mechanical strength but low corrosion resistance. The corrosion resistance of pure aluminum is good, but its mechanical strength is poor, which restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc, and other metals into aluminum to make various types of aluminum. Aluminum alloys greatly increase the mechanical strength of aluminum and greatly expand its application range, but its corrosion resistance is worse than that of pure aluminum, and therefore it may be corroded by oxidation. This requires powder coating to protect the aluminum profiles.
In addition to high corrosion resistance, powder-coated aluminum profiles have many advantages such as color diversification, good surface texture, etc., echoing with various colors of architectural exterior paints to adapt to different architectural styles.
Road Salt is the Natural Sea Salt which made from sea water or deep underground brine. Road salt or De-Icing Salt is the most efficient way to control ice on the road. Safe road salt by effective up to -12 °C and is perfect for de-icing pavements, parking lots and roads. Our road salt can be ordered and delivered in individual packets or in bulk. In addition to road salt, we also supplies brine. With a concentration of 23% NaCl, the brine works quickly and efficiently up to -21 °C.
How road salt works:
Road salt works by lowering the freezing point of water via a process termed freezing point depression. In a nutshell, the salt breaks into its component ions in a small amount of liquid water. The added particles make it more difficult for the water to freeze into ice, lowering the freezing point of the water. So, for road salt to work, there needs to be a tiny bit of liquid water. This is part of the reason why road salt is not effective in extremely cold weather when water would freeze too easily. Usually, an extra source of water is not necessary because there is enough liquid water present, either coating the hygroscopic salt pieces or produced by friction from traffic.
When cold weather is forecast, it is common to pre-treat roads with brine, which is spreading road salt granular or a solution of salt and water.This helps prevent ice from forming and reduces the amount of road salt needed to de-ice the surface later. Once ice starts to form, road salt is applied in gravel or pea-sized chunks. Road salt may be mixed with dry or damp sand to aid the process, too.
