[China Aluminum Industry Network] Aluminum is a light metal with silvery white luster. Its corrosion resistance has the following two characteristics:

1. The higher the purity, the better the corrosion resistance. As we all know, pure aluminum reacts with oxygen in the air and produces a thin and dense natural oxide film on the surface of aluminum, which is faster than other metal oxide films. Thickness, which prevents the harmful gases and moisture in the air corrosion, played a protective role;

2, although the corrosion resistance of pure aluminum is good, but the mechanical strength is poor, which restricts the application of aluminum to a certain extent, therefore, people add appropriate amounts of magnesium, copper, zinc and other metals in aluminum to make various types Aluminum alloys and aluminum alloys have high mechanical strength, which greatly increases the mechanical strength of aluminum and greatly expands the application range. Although aluminum alloys have high mechanical strength, they have poorer corrosion resistance than pure aluminum, and therefore may be corroded by oxidation. This requires the powder coating to protect the aluminum alloy profiles. The aluminum alloy is widely used in buildings, doors, windows, curtain walls and other products for many years because of its small specific gravity, easy processing, and large mechanical strength. ,

After powder coating, aluminum profiles have many advantages such as high corrosion resistance, color diversification, and good surface texture, which echoes with different exterior wall coatings to create colorful buildings.

Excavator buffer HBY seals is  used in combination with rod packing to absorb the impact and fluctuating pressure at high load, to isolate high temperature fluid, and to improve the durability of the packing.Hydraulic Buffer Seal HBY is used together with rod seal.In this way it can improve seal durability because after absorbing shock and wave in high load capacity it can be isolated from high temperature fluid.
