Effect of Different Coating Speeds on Film Thickness Consistency in an Adjustable Film Applicator
This paper studies the influence of coating speed of an adjustable film applicator on film thickness uniformity. In the experiment, the coating blade gap was fixed at 100 μm, and a resin solution with a viscosity of 200 mPa·s was used to prepare films at five speeds ranging from 10 to 80 mm/s, followed by thickness measurements.
Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions. Dual-element probes offer a smaller dead zone compared to single-element probes, and delay-line probes are suitable for thin-wall and high-temperature applications.

Performance Comparison and Selection Guide Between Electric Vibration Tables and Hydraulic Vibration Tables
Electric shakers and hydraulic shakers are two commonly used vibration testing devices, each with different working principles. When selecting a model, factors such as test frequency, specimen weight, displacement requirements, and cost need to be considered.
Selection Differences Between Random Vibration and Sine Vibration Tests
This article primarily discusses the differences between random vibration and sinusoidal vibration tests. Sinusoidal vibration uses a periodic signal at a single frequency, making it suitable for identifying resonance points and conducting fatigue tests. Random vibration, on the other hand, employs a broadband random signal to simulate real-world environments, such as transportation jolts, making it more appropriate for reliability acceptance testing.
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.
