Study of Physical Defibration of Rice Straw for Pulp Mold

The mechanical defibration of rice straw was conducted to determine a feasible method for its diverse utilization as an alternative wood fibers, especially use raw material pulp mold. In this study, dry and wet processes were used defibrate the characteristics defibrated obtained using different analyzed. Two types methods such valley beater process micro-grinder applied. Compared process, increased fines generation. Alkaline pretreatment high temperature conditions efficiency both processes. grinding mill hammer resulted in higher fiber generation than exhibited with respect straw; moreover generated more rather fibers. strength mold manufactured fibers via molds fibers/fines other because process.
