Chemically, there are different minerals composed of sand and dust particles. Due to the humid environment, they will undergo acidic or alkaline reactions, causing corrosion to materials and equipment. For example, large amounts of hydrous aluminosilicate materials in many soils will create an acidic environment, while other hydrated saline soils will produce an alkaline environment.
The sand and dust test chamber stays on the metal surface of the machine equipment, and the suspended sand and dust can have a chemical corrosion effect on it. Sand dust can be combined with other environmental factors, such as in a humid and SO2-containing environment, it can cause severe corrosion on metal surfaces. Sand dust contributes to corrosion damage in two cases: the first case is that the sand dust particles can absorb active gases in the atmosphere such as SO2, and the ability and degree of corrosion of the metal surface depends on the sand dust in that environment Chemical properties and the relative ease of corrosion of metals. Another situation is that for metal corrosion, inert and hygroscopic sand can be used as a corrosion source or catalyst.
For the destruction in the sand and dust environment, we can take the following methods to reduce or even avoid it:
For the exposed surface of the sand and dust test chamber, choose wear-resistant materials, such as attaching a layer of polyurethane with a thickness of 18 inches to the metal wing blades of the helicopter
Install a filter at the air inlet of the engine intake system so that clean outside air flows into it and operates normally;
For exposed surfaces that are easily eroded by sand and dust, such as bearings, we can install a dust cover;
Sand and dust test chamber can be frequently replaced with lubricating oil and cleaning equipment;
Electronic equipment that is in a place with high sand and dust hazards should be grounded or properly comprehensively protected so as to avoid the generation of static charges;
For the sealing place, especially for electronic equipment, such as the relay can be switched, it should be well sealed;
Adopt some designs to minimize the formation of sand erosion corrosion film.
The Anomatic series of high-quality deep drawn Aluminum Canisters is designed to be compatible with your chosen valves, Actuators and drug formulations. Our deep drawing process ensures a consistent side wall thickness using high strength aluminum which is far superior to other forming methods. The aluminum is work hardened during the deep draw process and the surface mechanically polished providing a smooth, hard internal finish suitable for use with both CFC and HFA propellants.
Aluminum anodization is an electrochemical process that enhances the strength, durability, and appearance of aluminum. When aluminum is oxidized, super-strong oxide (anodic) layers [grow" on the surface of the metal. These new layers are highly resistant to wear and corrosion.
The exacting part to part consistency achieved with our unique anodizing system cannot be obtained with conventional hoist line systems. Conventional anodizing systems present parts with varied coating thicknesses and voids formed due to air pocketing.
