Study of bonding plywood using nanocrystalline cellulose

Abstract

The possibility of applying nanocellulose as additive in the production of plywood is considered. This involves its activation by physical methods (ultrasonic treatment and PMF). Increase in the strength of the resulting material by increasing the strength of the adhesive joint is experimentally established. But in this case, the strength of the adhesive joint was higher the strength of birch veneer sheets, veneer pack was amplified with basalt material. Studies have also shown that replacement of the two plies on the basalt fabric beneath the outer layers of plywood, gives an increase in tensile strength by adhesive seam compared to the control sample by 220 %.
