Abstract
In this study, in order to gain the best Particleboard made of production, the effect of three factors, resin content, hardener content, and press time on the static bending strength, Internal board, water absorption, and thickness swelling after 2, and 24 hrs. Immersion in water of boards mades are studied. 54 boards were made and after measuring of their physical and mechanical, the results was analyzed with using the factorial completely randomize design.
The results show that increasing resin content causes better quality of properties of boards such as bending strength, Internal bound, and dimensional stability.
Increasing of press time from 5 to 5.5 min. Causes better bending strength, Internal board and dimensional stability of boards where, with increasing of press time from 5.5 to 6 min are observed that all of the mechanical properties of boards were reduced.
Totally speaking, it can be noted that changing of bending properties, internal bound, water absorption, and thickness swelling after 2, and 24 hrs. Immersion in water of boards made show that optimum condition are 11% resin, 2% hardener, and 5.5 min press time for making particle board made of Bagasse.
