Study on Talc Grade and Abrasion Value Part ①: Mineral Structure Determines Abrasion Performance
Talc powder is a core functional filler in the papermaking industry, widely applied in cultural paper, packaging paper and specialty paper, normally accounting for 10% to 30% of the paper’s dry weight. As the operating speed of modern paper machines exceeds 1500 meters per minute and papermaking equipment becomes increasingly sophisticated, the abrasion characteristic of fillers has become a critical factor affecting paper machine operational stability, equipment service life and production costs.
