Paper smoothness meter

Arbetsprincip

The tester measures air leakage between the sample and a glass plate under controlled pressure. Higher leakage indicates lower smoothness. Results are expressed in Sheffield Units (ml/min).

Provningsprincip

Sample Placement: Secure the material on the glass plate.

Vacuum Application: Apply vacuum to draw air through the sample-plate gap.

Flow Rate Measurement: Calculate leakage rate to determine smoothness.

Ansökningar

Used in paper mills, printing houses, and packaging labs, the tester ensures materials meet surface quality standards for coatings, printing, and conversions. Compliance with ISO/TAPPI methods ensures reliable data for quality control and process optimization.

This guide provides technical insights to support informed decisions when selecting or operating paper smoothness testers, ensuring accurate surface quality evaluation.
