Abstract

      This research studied influences on penetration and retention of disodium octaborate tetra hydrate in Full-Cell process. The conditions of experiment were held 0.2 bar vacuum pressure, applied 8, 10, 12 bar pressure and hold 0/60, 10/50, 20/40 (min/min) vacuum/pressure time. The results show that, 10 bar pressure and time 0/60 give the highest %BAE (boric acid equivalent) results about 1.11, 14.82 ppm. Compare with wood standard from factory witch boron concentration was 1.982 ppm. When time condition were 0/60 to 20/40, provide a decreasing trend of boron retention .When time condition were 0/60 and pressure increased from 8 bar to 10 bar pressure, provide an increasing trend of boron retention. When the pressure was raised from 10 bar to 12 bar pressure, provide a decreasing trend of boron retention
