How to tackle heavy dust in friction-material mixing: the dust-suppressed fibre approach
Abstract
Heavy dust at the mixing station harms workshop occupational health and also causes material loss and airborne contamination. Beyond standard enclosure, extraction and workstation protection, choosing surface-treated “dust-suppressed” fibre at the raw-material end is one viable route: it reduces fine-fibre dusting to improve the working environment, but dust suppression is integrated management that must be implemented together with workshop ventilation and personal protection.
Why dust matters: the mixing station is where dust concentrates in a friction-material workshop. Heavy dust causes material loss, equipment wear and a messy environment, and — more importantly — relates to workers' occupational health. Dust suppression is therefore not a bonus but a basic requirement of workshop management and occupational health, needing engineering control, management measures and personal protection together.
The raw-material-end view: untreated mineral fibre sheds fine fibres and powder more readily during feeding and mixing. Surface-treated fibre (company-brochure surface-treatment level ≤6%) has an adjusted surface state that can, to some extent, reduce fine-dust dispersion and improve feeding dusting — a way to assist the working environment from the formulation side. Boundary: surface treatment helps dust suppression but cannot replace workshop ventilation, extraction and personal protection; the effect also depends on feeding method and equipment enclosure, and should be assessed on site.
Supporting measures: engineering — enclosed mixing, local exhaust and dust extraction, sensible feeding; management — standardise feeding and cleaning, inspect extraction equipment regularly; personal protection — provide dust masks per the SDS and workstation requirements. Use the 2026 bilingual SDS for storage/handling health-and-safety information. To put “dust-suppressed fibre” into selection: make feeding/mixing dusting an observation item in sampling; compare dusting of treated vs untreated fibre at the same station; consult the SDS; and assess raw-material improvement together with engineering and management measures rather than expecting one method to solve it completely. This article avoids absolute claims like “completely dust-free” — dust control can only bring exposure down to a manageable level.
