Cleaning Roller

GRISH-referenced Cleaning Roller for LCD panel processing, composed of a high-strength elastic polymer composite, elastic buffer layer and functional abrasive cleaning layer joined using an adhesive. The original manufacturer describes a compliant flat cleaning/grinding surface with a chip-holding structure and spiral open-loop grooves to promote debris removal and reduce surface scratches. Source abrasive designations are AO, AOH and CaCO₃ (calcium carbonate); the source does not define AO or AOH chemical identities and no grade/material is assigned to an individual size. GRISH source-listed sizes: Ø70 × 644 mm and Ø70 × 544 mm; custom sizes available by request. The source does not map abrasive selections to roller sizes, and no discrete commercial models are supplied. Claimed scratch reduction, stability and yield are external manufacturer assertions, not HANS-certified performance.
