| Popis: |
Disposal of fallen leaves in city area has become serious issue because of increasing amount of the fallen leaves and of decreasing handling amount of daily waste incinerating facility or landfill. In order to increase the usability of fallen leaves, the sheet-like composite was prepared through pretreatment processes and manufacturing processes of fallen leaves. The crushed fallen leaves were fractionated by using 10 mesh and 40 mesh screen, which could divided the stem and the lamina because the lamina of the fallen leaves was more breakable than the stem. The effects of fallen leaves particles size on the properties of the sheet-like composite were evaluated. The fraction between 10~40 mesh of the crushed fallen leaves resulted in the higher strength properties of the composite than that of the larger size particles or the smaller size particles. The bulkier structure of the composite made of 10 mesh fraction showed higher water resistance property and lower water holding capacity. The density and the strength property of the composite was controlled by addition of red clay as filler. The surface treatment with rosin resulted in the higher water resistance and the neutralization of alkali pH. |
