Patent

CA 2063115

A rigid fiberboard suitable as a replacement for the natural woods presently used for the manufacture of pencils is provided. The fiberboard essentially comprises a fiber network together with a filler and binder. A lubricant is added to improve the sharpening characteristics of the fiberboard, and dimensional stability is preserved by incorporating a water proofing agent to minimize the absorption of water by the fiber network.

Panneau de fibres rigide destiné à remplacer le bois naturel utilisé actuellement dans la fabrication de crayons. Le panneau de fibres comporte essentiellement un réseau de fibres, une matière de charge et un liant. Un lubrifiant est également ajouté au panneau pour améliorer ses caractéristiques d'aiguisage. On conserve la stabilité dimensionnelle en incorporant au panneau un agent d'étanchéité afin de réduire l'absorption d'eau.
