EVALUATION OF MATERIAL COMPATIBILITY, THERMAL DEGRADATION AND MECHANICAL PROPERTIES STUDY OF THE PLY BOARD BY USING WOOD PROTECTOR SCAPOR.

The study was aimed to evaluate the chemically compatibility, thermal degradation of Wood Protector SCAPOR (An eco- friendly) as glue line preservatives (GLP) as well as the mechanical properties of the plywood made by using Wood Protector SCAPOR as a glue line preservative. 12mm Plywood samples at different concentration (0.5% to 5%) preservative were manufactured randomly by using Wood Protector SCAPOR as a glue line preservative with combination of different wood veneer species and taken for mechanical properties study like MoR,MoE,GSS,Tensile strength etc. To assess the chemically compatibility Wood Protector SCAPOR was added with both phenolic and amino resin at different concentration (0.5% to 5%) and adhesive properties was studied .The test results shows that there was no adverse effect of the GLP on the adhesive properties like PH, bonding, rheological properties and shelf life for manufacturing of wood composites. To carry out the thermal degradation study of the glue line poison Wood Protector SCAPOR of 1% was mixed with resin and DSC – TGA study carried. The mass loss (%) Vs. temperature graph was plotted to assess the degradation study of the Wood Protector SCAPOR .The analysis data shows the material was not degraded before the temperature 240 to 2500C which is appx. 1000C more than the normal operating temperature to manufacturing of wood composites .The result of MoE, MoR, Glueshear strength test at 1.5% to 3% concentrations also show satisfactory limit of acceptance as per Indian standards.
