Sandblasted Steel Roughness Measurement Device

The sandblasted steel roughness tester measures the microscopic undulation depth of steel after sandblasting by scanning the surface profile with a stylus. It is used to evaluate the quality of surface treatment and ensure coating adhesion, controlling the sandblasting grade in corrosion protection projects for ships and bridges.
Selection
Select diamond or tungsten steel styli based on the hardness of the tested material; the measurement range must cover Ra 0.1-25 μm; choose oil-proof and dust-proof models considering the on-site environment; confirm that the instrument complies with ISO 8503 and GB/T 13288 standard requirements.

Roughness Measurement Instrument Selection: Contact vs. Non-Contact
This article introduces the differences between contact and non-contact methods when selecting a roughness measuring instrument.
Comparison of Selection Parameters for Stylus and Laser Roughness Measuring Instruments
Stylus-type roughness measuring instruments perform contact scanning to measure two-dimensional profile parameters in accordance with standards such as ISO 4287, while laser-based instruments utilize non-contact optical principles and refer to ISO 25178.
Contact angle measuring instrument measures the surface wettability of paper.
The contact angle goniometer evaluates wettability by measuring the contact angle of a liquid droplet on the surface of paper, based on the principle of Young's equation. The static drop method is commonly used for measurement, requiring control over sample flatness, environmental conditions, and droplet volume, while also considering the influence of surface roughness.
Surface Roughness Tester Evaluates the Impact of Substrate on Adhesion
This article primarily explores how the surface roughness of the substrate affects the adhesion of coatings or bonds.
Paper smoothness and roughness
Paper smoothness and roughness are key parameters that describe the flatness of the paper surface, and they complement each other. Smoothness refers to the extent to which the paper surface approaches an ideal plane, while roughness reflects the amplitude and frequency of surface irregularities.
