Ability of Agricultural Wastes Employ in Manufacturing of Thermal Insulator

Abstract

Abstract:We chose rice husk for this research and we have been grinded and sifted on three phases (20,60, 100, mesh) as a primary stage ; then different kinds of adhesives were used to form the grinded husk panels with certain dimensions. The adhesive that has been used in this research is sharris, which is an agricultural product made up with industrial starch, phenol formaldehyde adhesive, acrylic and polystyrene.Grinded husk were manufactured by mixing different kinds of adhesives individually within templates which have been pressed and left to dry at normal weather conditions. Different kinds of tests were done on these panels like endurance, hardness, moisture resistance, fire retarding and most important thermal conductivity. Rice husk has a thermal conductivity of about 0.0359 W/(moC)the values compare well with the thermal conductivity of excellent insulating materials"(Houston,1972).
