Anticorrosive coating is an indispensable part of paint coating, that is to say it belongs to a type of paint coating, we can divide it into conventional coatings, industrial anticorrosive coatings and special coatings.

1. What is anticorrosive coating?

   Conventional anticorrosive coating can be considered as a coating product that can prevent or slow down the corrosion of metals and other materials under normal circumstances. Its role is to protect the service life of metal.It is a term for heavy-duty anticorrosive coatings. It is aimed at conventional coatings. It can be applied in relatively harsh environments.
     In addition, we also have a kind of classification of coating products: special coatings, such as high temperature resistant anticorrosive coatings, antistatic coatings, that is, like high temperature resistant anticorrosive coating products. It can withstand high temperature. Generally, high-temperature resistant anticorrosive coatings can withstand high temperatures of several hundred degrees, while professional coatings with special treatments can withstand high temperatures to work. There are also antistatic coatings. In addition to the general chemical corrosion protection of the coating object, this coating product can also discharge the static electricity accumulated in the product in a short time, thereby protecting the coating object from being damaged by static electricity.

2. The thickness of the anticorrosive coating

The coating thickness is an important indicator of whether the anticorrosive coating works. Coating thickness measured by an anti-corrosion coating thickness gauge is one of the most important quality inspection indicators of an anti-corrosion coating. For anti-corrosion coatings, anti-corrosion coating thickness gauges are almost essential instrument for coating thickness measurement. The coating has been applied in various industries and it is easy to detect. It has developed into many types such as magnetic induction, ultrasonic, eddy current and simple measurement. Ferromagnetic metals are very different from non-ferromagnetic metals. Therefore, special magnetic thickness gauges are used when measuring the thickness of anticorrosive coatings on ferromagnetic metal substrates, but some anticorrosive coating thickness gauges are currently available. Simultaneous measurement of two types of metal substrates, such as anti-corrosion coating thickness gauge LS220H.

3. Which products can measure the magnetic thickness 

Magnetic induction thickness measurement can be used to measure the thickness of the non-magnetic coating on the magnetically permeable substrate. Generally, the relative permeability of the substrate is required to be above 500 μm. If the coating material is also magnetic, the difference from the permeability of the substrate must be sufficiently large. At present, magnetic thickness gauges are often used for coating thickness detection of various products such as car paint thickness, iron-based surface rubber thickness and enamel thickness.
     The magnetic induction
coating thickness gaugeuses a probe with a coil around a soft core to be placed on the object. The resolution of modern magnetic coating thickness gauge can reach 0.1μm, the allowable error can reach 1%. The measurement range can reach 10mm. The magnetic induction coating thickness gauge can be used to accurately measure the paint layer, porcelain, enamel protective layer, plastic, rubber coating, various non-ferrous metal coatings including nickel chromium and various anticorrosive coatings in petrochemical industry.
