Why should medical device aluminum profile be powder sprayed?

Update time : 2022-11-14 18:48:36

The higher the purity of the medical device aluminum profile, the better the corrosion resistance. Pure aluminum will have consequences with oxygen in the air. A thin layer of fine natural oxide film will be produced on the surface of the medical device aluminum profile. It is much thicker and faster than other metal oxide films, and then prevents the decay of harmful gases and water in the air and plays a maintenance role.

Although the corrosion resistance of pure aluminum is good, the mechanical strength is poor, which restricts the use of medical device aluminum profile to a certain level. Therefore, we add appropriate magnesium, copper, zinc and other metals in the medical device aluminum profile. Made of various types of aluminum alloy, aluminum alloy mechanical strength is high, so that the mechanical strength of the medical device aluminum profile greatly improved, the use of the scope is greatly expanded, although aluminum alloy mechanical strength is high, but the corrosion resistance is worse than pure aluminum, so it is possible to be corrupted by oxidation.

Medical device aluminum profile light weight, high strength, corrosion resistance, etc., generally used for wheelchairs, stretchers, nursing beds, medical accompanying chairs, medical equipment and so on. This requires powder coating to maintain the medical device aluminum profile.

After powder coating, medical aluminum has high corrosion resistance, color diversity, good nominal texture and many other advantages. The medical device aluminum profile after powder spraying has a service life of 30 years under normal conditions. Its surface coating in 5-10 years to ensure that no fading, no discoloration, no cracking. Its weather resistance and corrosion are better than ordinary aluminum color diversity.
