When spraying, the thickness of the coating is always emphasized, and I didn t have long to learn ho

Each spraying company and powder coating factory has different methods for determining the thickness of coatings, I am a technician working in VIE powder coating factory, I have some knowledge in this area, I hope to help you:

1) Determine the thickness of the wet film. The simpler way is to use a metal plate that can be carried in a pocket, with rectangular teeth on both sides, and the two planes at both ends of each tooth shape are on the same horizontal plane, and the middle teeth are different heights from the horizontal plane in turn. When used, it is placed vertically in contact with the test surface, and the maximum reading of the toothed adhesion wet film is the thickness of the wet film.

2) Determine the dry film thickness. At present, dry film thickness gauges are commonly used. It can also be used mechanically, such as a lever dry minute scale, to determine the thickness of the coating on the metal base plate, due to the limitations of the lever in the structure of the minute scale itself, it can only be used to measure a small area of the test plate.

For other substrate materials used in coating, such as glass, wood, paper, etc., to determine the thickness of its paint film, then generally use a lever on the minute scale. The thickness of the glass bottom plate is measured first, and then the total thickness of the glass plate and the paint film is measured after the paint is applied, and the total thickness is subtracted from the thickness of the glass bottom plate, and the thickness of the paint film can be obtained.

I heard that there is now an imported non-contact non-destructive thickness gauge, which can measure the thickness of the dry film in the wet film state, it seems to be called the Magician Ato, you can search it on the Internet.

The thickness of the paint is between the thickness of the edges.

The hole in 13 is easy to get on with a little lead, but it is relatively tight, and the hole is difficult to seal.

The thickness of the spray is between 25 and 65 microns.

Hello, the coating thickness is between 25 and 65 microns.

The thickness of the paint is between the thickness of the edges.

The hole of 13 is slightly easier to get on, and the hole is tighter, and the hole is difficult to cover with the seal.

The thickness of the spray is between 25 and 65 microns.

The thickness of the coating film of the roller coating is mainly controlled by adjusting the gap and circumferential velocity ratio between the reclaiming roller and the coating roller (or adjusting the reclaiming roller).

Due to the same direction of the roller, the gap between the whole roll is adjusted and the thickness of the coating film increases with the increase of the gap. However, this type of roller coater is only suitable for low-viscosity coatings, and its film thickness adjustment control range is within 20.

Since the reclaiming roller and the coating roller rotate in the same direction as the napi, by adjusting the gap between them, the thickness of the coating film increases with the increase of the gap. Similarly, adjusting the circumferential velocity ratio of the reclaiming roller can also adjust the thickness of the coating film, and the circumferential velocity ratio increases, the coating amount of the coating increases, and the thickness of the coating film increases with the thickening. This method of adjusting the gap between the steel roller (reclaiming roller) and the rubber roller (sitz bath covering roller) to control the thickness of the coating film must be determined according to the viscosity of the coating, the coating thickness of the coating film is difficult to coat the low viscosity, and the coating film thickness of the high viscosity will be high, and the control range of the coating film thickness of the actual bend is 1 70 (wet film thickness).
