Tinplate smear

The tinplate coating smear is a test piece formed by applying a coating onto a tin-plated steel sheet and then baking it. It is used to evaluate the suitability of coatings for metal packaging materials by observing properties such as coating adhesion and glossiness. It is commonly employed for quality control in food packaging, such as cans and bottle caps.
Selection
When selecting, consider matching the substrate's tin plating amount to the actual product, ensuring the coating thickness meets industry standards, aligning the surface treatment method with the production line, simulating actual processes in baking conditions, and covering key testing indicators such as adhesion and corrosion resistance.

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.
The film coater applies a conductive film onto transparent substrate test pieces.
This article introduces a method for uniformly coating conductive films on transparent substrates such as glass or plastic films using a film applicator.
The coating machine applies an anti-reflection coating on the surface of optical lenses.
A coating machine is a precision device used for depositing anti-reflection coatings on the surface of optical lenses. Based on the principle of light interference, it forms a thin film of specific thickness on the lens surface through physical or chemical methods to reduce light reflection and enhance light transmission performance.
Multi-angle colorimeter detects color changes in pearlescent coatings.
Pearlescent coatings contain special flake pigments that produce color effects that vary with the viewing angle, known as "goniochromism." Traditional single-angle measurements struggle to accurately capture this characteristic.

The Lovibond tintometer determines the color of oils and fats by visually comparing them with standard glass color standards, with results expressed as numerical codes. During operation, clarified oil samples are poured into the colorimetric cell and compared with color chips under a stable light source.

If the standard disintegrator procedure for fiber dissociation is not done correctly, the first step of paper strength testing is already compromised.
Fiber disintegration is the first step in paper strength testing. If the operation is not standardized, such as inaccurate concentration, excessive time, or incorrect rotational speed, it can lead to fiber breakage or uneven dispersion, resulting in inaccurate strength data for the prepared hand sheets.
