Pneumatic valve corrosion and the solution

corrosion, pneumatic valve, pneumatic valve is often understood as metal materials in the chemical or electrochemical environment under the action of the damage. Due to the corrosion phenomena appeared in the metal and the surrounding environment of spontaneous interaction, therefore, how to the metal with the surrounding environment or more isolated from the use of non-metallic composite material, which become the common concern.
, it is well known that the metal corrosion damage to the role of the pneumatic valve, reliability and service life have a considerable impact. The role of mechanical and corrosion factors effect is greatly increased the contact surface of metal general wear. Pneumatic valves in the process of operation, the friction surface of the total amount. Pneumatic valves in the process of operation, because of the friction surface at the same time, the role of the mechanical and metal chemical or electrochemical interactions with the environment the result of wear and tear. For pneumatic valves, the piping work climate conditions of complex; Oil, gas and oil reservoir water medium such as hydrogen sulfide, carbon dioxide, and the emergence of some organic acids increased its destructive power on the surface of the metal, thus losing the ability to work quickly.
, because the chemical corrosion of metals depends on temperature, friction parts of mechanical load, lubrication material contains sulfur and its stability of acid and the duration of the medium contact and metal catalysis of nitriding process, erosion corrosion substance molecules on metal conversion speed and so on. Therefore, metal anticorrosion method of pneumatic valves ( Or measures and applications of synthetic materials pneumatic valve, pneumatic valve industry has become the one of the research topic.
pneumatic valve, metal anti-corrosion, can be understood as a coating on metal pneumatic valve to protect its is not subject to the conditions of the corrosion protection layer ( Such as paint, paint, lubricating material, etc. , make the pneumatic valve whether in the manufacture, storage, transportation or in the whole process of its use is not affected by corrosion.
pneumatic valve, metal anticorrosion method depends on the demand of protection period, transportation and preservation conditions, pneumatic valve structure characteristics and material, of course, to adapt to consider the economic effect of the lifting anticorrosion.
metal pneumatic valve and its components anticorrosive method mainly has four kinds:
and volatile corrosion inhibitor in the vapor in the atmosphere ( With the inhibitor paper packages, blowing inhibition of air chamber through the products and so on.
and utilization of the inhibitor for water and alcohol solution.
, will be corrosion ( Protection of material apply to the pneumatic valve and its components surface thin layer.
, will be the inhibitor film or thin layer of polymer on pneumatic valves and parts surface.
