Anticorrosive coating thickness measurement

When it involves dry film thickness gauges, many of us will find it unfamiliar, but when it involves dry film, it's something that's closely associated with people's lives. The steel, automobile and a few parts assembly surfaces that we will see everywhere are dry film layers, and their thickness depends on the detection of the dry film thickness gauge.
When spraying paint on exposed parts or steel, the industry always pays special attention to the thickness of the dry film. Because the dry film thickness gauge are often wont to detect the particular thickness of the dry film very accurately, the dry film thickness gauge is widely utilized in the sector of anti-corrosion coating.
We spray dry film on steel or bare metal mainly to stop oxygen and moisture from entering, then redox reaction. Reasonable and effective isolation of air and water can reduce the probability of rusting of parts. It can greatly extend the service life. additionally , the dry film with a particular thickness are often abrasion-resistant and scratch-resistant. The addition of colourful coloring agents also can improve the looks of the parts, cater to people's aesthetic needs, and may also leave an honest visual impression publicly places. .
for many people, they often mistakenly believe that the thicker the dry film thickness, the higher , but it's not. generally , a dry film with a moderate thickness will have good air permeability, and therefore the preservation effect of the anti-corrosion coating are going to be better. once we use the dry film thickness gauge to check , we usually find that the excessively thick dry film exceeds the quality , which brings greater difficulty to the workers in spraying, and its uniformity and flatness are lacking. Of course, the dry film layer that's too thin will wear prematurely, the effect of isolating the surface air isn't good, and it cannot protect the merchandise , and it's susceptible to unevenness and pits after the second repair spraying.
From the attitude of real world , a dry film with too high thickness also will cause serious waste of paint and a big increase in cost. this is often one among the explanations why many construction industries strictly use dry film thickness gauges to detect dry film thickness.
Dry film thickness gauge plays a really important role within the field of anti-corrosion coating. The importance of measuring the dry film thickness is to make sure that the coating reaches the required thickness and avoid premature failure of the coating thanks to improper thickness. In steel anticorrosive spraying, the dry film thickness must be measured with a dry film thickness gauge after the coating is totally dried.
