Coatings with physical, chemical, or other methods, in the metal or non-metallic substrate surface to form a layer with a certain thickness (generally more than 10um), different from the base material and has a certain strengthening, corrosion, or special features of the coatings.
What kind of anti-corrosion coating works best?
1. Anti-corrosion coating with good adhesion. Whether the anti-corrosion coating can be firmly attached to the metal substrate is one of the key factors in its ability to play the role of anti-corrosion. The stronger the adhesion of the anti-corrosion coating, the better its corrosion resistance, and the more durable the coating.
2. Anti-corrosion coating with strong anti-aging and stability. If the anticorrosion coating has poor anti-aging properties and low stability, it directly affects the effect of anticorrosion. Therefore, the anti-corrosion coating should have good anti-aging properties and can maintain stable properties in low temperature, high temperature, water, and chemical reagents.
3. Anti-corrosion coating should have a certain mechanical strength and considerable adaptability to external stress. Anti-corrosion coating of the conventional mechanical properties of hardness, flexibility, impact resistance, abrasion resistance, and other characteristics, considerable adaptability to external stress, and a certain mechanical strength of the anti-corrosion coating effect is better.
Do I have to add the anti-corrosion coating?
It is necessary to decide whether to add anti-corrosion coating and the thickness of the coating according to the site conditions. First of all, we must confirm that the radar level meter to measure the medium is a strong acid, alkali media, or other corrosive organic solvents, according to the characteristics of different media to decide whether to add anti-corrosion coating and its thickness.
In addition to the characteristics of the medium itself, the pressure and temperature of the tank also have a great impact on corrosion. Generally with the increase in temperature, the rate of corrosion will be accelerated. Similarly, with the increase in pressure, corrosion will also increase. Therefore, the temperature and pressure to understand clearly.
Is there any other way to prevent corrosion other than adding an anti-corrosion coating?
There are, in addition to the addition of anti-corrosion coatings, corrosion-resistant materials can be selected for the manufacture of meter components, such as polytetrafluoroethylene. It is also possible to isolate the measured medium from corrosion of the radar level meter by blowing in air or other inert gases.
