アカマツ材アスプルソドパルプ・メタクリル酸メチルグラフトポリマーより調製した繊維板の性質(2) : 繊維板の吸水寸法安定性と強度

Abstract

The mechanical and strength properties of the fiberboard made from Asplund pulp-MMA graft copolymer have been investigated. The dimensional stability and strength properties of the board were highly influenced by the density and pressing conditions. Generally, the dimensional stability in water soak increased with increasing percent grafting, but the strength properties (bending strength, etc.) did not increase with increasing PMMA content so much as the dimensional stability.
