Increasing the fire strengh of particle boards by using some mineral fibers

It was aimed in this study, to determine the effect of glass and stone wool with 10%, 15% and 20% ratios to fire retardant, some physical and mechanical characteristics. Particle boards obtained from a mixture of 50% Crimean pine (Pinus nigra), 30% Eastern Black Sea oak (Quercus Pontica), 15% quaking aspen (Populus tremula) and 5% workshop shavings from Kastamonu Entegre A.Ş. in Kastamonu. 70 particle boards at a thickness of 14 mm and the dimensions of 45 x 45 cm2 were manufactured by taking a density of 0.64 g/cm3. The following tests were applied to specimens: density (TS EN 323), amount of moisture (TS EN 322), increase in thickness in water (TS EN 317), fire retardant (DIN 4102), perpendicular bending resistance to the board surface (TS EN 310), modulus of elasticity (TS EN 310), parallel tensile resistance to the board surface (ASTM 1037), perpendicular tensile resistance to the board surface (TS EN 319), parallel shearing resistance to the board surface (TS 5192), screw tensile resistance parallel to the surface and perpendicular to the surface (TS EN 320 and TS EN 13446) and the data analyzed with SPSS-15 package program. The use of glass and stone wool increases all values related to burning characteristics of particleboards from 30% up to 335% and the cause of a decrease from 39% up to 75% in all values related to mechanical characteristics. The increases and decreases are not linear and are generally in decreasing ratios.
