The effect of some boron compounds on properties of particle board

In thıs study boron compounds or fire retardant was added to particle board sand the irproperties were determined. Fire retardants (BX, BA and ÇB) were added as 3%, 5% and 7%. Forthe three layered particle boards uf resin was used forsur face layer swith 10% and for middle layer it was 8%. Physical, mechanical and fire properties of particle boards were determined. Accounting to the test, water up take and thicknesss welling was affected by fire retardants in a negative may. As fire retardant ratioin creases, thicknesss welling and water up take properties worsened. Bending strength and internal bond strength as mechanical properties were also negatively affected by fire retardant addition. Modulus of elasticity did not changes ignificantly. BX, BA and ÇB improved the particle boards fire performance. The best result was obtained from 7% BA added board swith 12,76% mass loss.
