Properties of Medium Density Fiberboard with Charcoal Incorporation

Charcoal with itsporous struaure enabks it to adsorbpollutants in gaseous or liquidphase, altho11ghit does not peifom1 as effictively as its correspondingactive char&0al Meanwhile,filediunl density.fiberboard (MDF) has beco111e one of the wood-basedpanels which develops rapidly.In relevant, this experimentdealt with charcoal addition duringMD F typefiberboard"1anufact11rebonded with ureaformaldel!Jde adhesive and shaped rmderdryprocess, and thefiber materials for theMDF were the mixture of mangiu,,,and mbbenvoodTMP (fhemro-MechanicalPulping)pulp at 3:1 proportion (w/w). Meanwhik,the fiber charcoal resulted from the carbonization of those mixed TMP pulp.Expectedly, the incorporation of charcoal could improve adsorption capacity of the res11ltingMDF. In this experi111e11t, the amounts of chama I as incorporatedi111pliedfrom the cof!lpositions of TMP fiber-charcoal mixture at consemtive!J 100:0, 90: 10, 80:20, and 70:30 based on oven dry weight. Observation was peifomud regarding MDF adsorption-capacities on benzene, chlorofor111, andfor111aldel!Jde (all ingaseous or vaporfomu). Results revealed that the greater the a11101mt of chamal added, thegreater also the adsorption capacity of MDF. Unfortunately,such has brought about the decrease in pllysical and mechanicalproperties of MDF Those MDF properties with TMPfiber-charcoal composition at 90:10 were similar to those of MDF control; and could satis.fl tbestandard of type-25]IS, exceptfor MOE (fype-15 ]IS) and internal bonding strength. Charcoal incorporation enabled the &0msponding to slow down the rate of the MDF fommldel!Jde emission.
