Study on the pressing technology of lenghtwise slicing rosewood veneer onto the surface of engineered wood flooring using high frequency pressing machine

Abstract

This article shower the results of study on the application of high - frequency pressing  machine on production of 2 - layer engineered wood flooring from a surface layer of 3 mm lenghtwise slicing rosewood veneer to a 12 mm plywood. The technological parameter of gluing 3 mm lenghtwise slicing rosewood veneer onto the surface of the plywood to produce technical flooring on pressing equipment heated with high frequency current was determined. The technological process includes following steps: Raw materials preparation; application of adhesive to coating materials; pressing coated boards on high - frequency presser; board stabilization; cutting boards; UV paint. The quality of engineered flooring was determined by the physical and mechanical properties according to current standards. The density was 0.78 g/cm³; thickness swelling was 4.36%; static bending strength was 55.93 MPa; static bending elastic modulus was 9,025.63 MPa; surface soundness was 1.1 MPa.
