Coating Thickness Gauge

The coating thickness gauge measures the differences in physical properties between the substrate and the coating using magnetic induction or eddy current principles. It is used for rapid on-site detection of coating thickness on metal/non-metal substrates and for quality control in industries such as automotive, shipbuilding, and construction materials.
Selection
When selecting, consider the substrate type corresponding to the magnetic induction or eddy current principle, clarify the measurement range and accuracy requirements, choose the probe shape based on curved or flat surfaces, check the instrument calibration certificate and protection rating, and verify whether the standard sheet matches the material being measured.

Comparison of Coating Accuracy between Laboratory Blade Coater and Slot Die Coater
This article compares the coating precision of blade coaters and slot-die coaters in the laboratory. Blade coaters are suitable for thick coatings, with simple operation but relatively large uniformity errors; slot-die coaters offer higher precision and better uniformity for thin coatings. The choice of equipment depends on coating thickness and precision requirements.

The wet film wheel gauge is a mechanical tool used to measure the thickness of wet coatings, operating based on the geometric relationship of three coaxial disks (two parallel outer wheels on the sides and an eccentric inner wheel in the middle).
Operating specifications for on-site measurement of coating wet film thickness using wet film combs
This article introduces the operational standards for on-site measurement of coating wet film thickness using a wet film comb gauge.

Selection of wet film thickness gauge range and accuracy requirements for comb teeth spacing.
When selecting a wet film thickness gauges, the key considerations are the measurement range and the accuracy of the comb teeth spacing. The range should cover the coating thickness with a slight margin to avoid being too small for measurement or too large, which could reduce resolution.

Wet film thickness gauge measures the wet film thickness of varnish.
The wet film thickness gauge is a mechanical tool used to measure the thickness of liquid varnish coatings. It operates by rolling the gauge so that the tips of its teeth contact the substrate and leave marks. The thickness value is then obtained by the operator reading the scale of the first tooth that becomes coated with the varnish.
Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
