| Abstract: | The production technology for making particleboard with isocyanate resin(YQJ A)was studied. The effects of hot pressing temperature, hot pressing time, density, moisture content( MC ),adhesive consumption and wax consumption were discussed in details. The results showed that the hot pressing conditions and MC of particles in manufacturing particleboard were the most important factors influencing panel's performances. A phenomenon of thickness swell( TS) parallelism was found and analyzed. The relation between irreversible thickness swell and 24 hr. thickness swell were obtained. 24 hr. thickness swell were improved by enhancing the irreversible thickness swell. The test result indicated that poplar particleboard by using YAJ A resin could meet the demands of Standard of DIN 68736 V100. |
