| Summary: | Two different types of waste melamine impregnated paper (WMIP) were generated in the
manufactured coated board product plants. First one is obtained when the neat décor papers were
impregnated (in the impregnation line) with melamine urea formaldehyde and other chemicals (WMIP1). The
second one is generated during the coating of the melamine impregnated papers on the board surfaces
(WMIP2). In this study, the utilization of both WMIPs in the production of particleboard as an adhesivereplacement
was investigated. First, waste melamine impregnated papers (WMIPs) granulated into flour
form using Pulverizator with cooling capabilities. Then, they were dry-mixed with surface and core layer
particles at 10% or 15% loadings. Three different WMIPs (WMIP1, WMIP2 or their mixtures - 70%
WMIP1+30% WMIP2) were used as adhesive-replacement. Mechanical properties including bending
strength, modulus of elasticity, internal bond strength and surface stability of the samples were determined
according to EN 310, EN 319 and EN 317 standards, respectively. Based on the results, the type of WMIP
had significant effect on all mechanical properties investigated. Particleboards produced with both 10% and
15% of WMIP1 loading provided adequate results for the related standards. The best result was obtained
when 15% of WMIP1 was used. It is concluded that WMIP1 might be used as an adhesive-replacement in
particleboard manufacturing and may provide economic and environmental benefits. |
