Anti-corrosion paint thickness test

Anti-corrosion paint has the effect of slowing down the corrosion of the environment to the protected materials. Although it cannot be completely isolated, it has the functions of shielding, corrosion inhibition and cathodic protection for the protected materials. Different corrosion environments have different requirements for the thickness of the anticorrosive paint of the steel structure. Only when a certain thickness of the anticorrosive paint reaches a certain thickness will there be a protective effect of response. Therefore, it is necessary to test the anticorrosive paint of the steel structure with a paint thickness gauge.
Linshang LS220H is a paint thickness gauge, iron and aluminum, which is mostly used for the thickness measurement of steel structure coatings. This instrument is small in size and easy to carry around; the instrument has high measurement accuracy and can be sent to authoritative national measurement Institute measurement.
Coating thickness gauge LS220H for measuring steel structure
Coating thickness testing standards for steel structure anti-corrosion paint:
C2 corrosive environment (low corrosion): service life/dry film thickness: low: 80; medium: 150; high: 200;
C3 corrosive environment (medium corrosion): service life/dry film thickness: low: 120; medium: 160; high: 200;
C4 corrosive environment (high corrosion): service life/dry film thickness: low: 160; medium: 200; high: 240;
C5-I corrosive environment (high industrial corrosion): service life/dry film thickness: low: 200;
C5-M corrosive environment (high marine corrosion): service life/dry film thickness: medium: 280; high: 320;
The above is the test standard for the thickness of anticorrosive paint in different corrosive environments according to "Code for Construction Quality Acceptance of Steel Structure Engineering". If when the design does not require the coating thickness, the thickness of the steel structure coating should be 150 μm outdoors and 125 μm indoors. Although anti-corrosion paint can not completely isolate the corrosion, it can effectively reduce the corrosion and extend the service life of the materials. The steel structure must be coated with the desired paint thickness in strict accordance with the corrosion level, and checked with a paint coating thickness gauge to ensure that the thickness of the anti-corrosion coating is qualified.
As a paint thickness gauge, LS220H can help you to detect the coating thickness of steel structure according to the standard.
