Rice Husk Flour

Different properties (tensile strength, elongation, modulus, impact strength) of rice husk (RH) reinforced polypropylene (PP) coupled by Maleic-Anhydride grafted Polypropylene (MAgPP) have been investigated. MAgPP is an effective coupling agent, not only in cellulosic-fibre filled polyolefine composites, but in rice husk flour filled polypropylene composite systems as well. It gives a utilizable construction polymer matrix composite (PMC) material even at a 40 wt.% RH filling degree. The strength and modulus increases by adding the rice husk but the elongation decreases in a non-monotonic way. Micrographs shows weak coupling in between RH and PP without MAgPP.

A parametric study on the flammability characteristics of rice husk-reinforced polyethylene composites with various material compositions was conducted to find the “best” composites’ formulation for fire retardancy. Composites were manufactured using rice husk, maleated anhydride polyethylene and linear medium density polyethylene. The blends for manufacturing of composites were selected using mixture design approach. The individual effects of each constituent material on the fire performance of composites by cone calorimeter were studied using trace and contour plots for the various thermal and flammability properties. Regression coefficients were also estimated for each measured response. The cone calorimetry results show that the addition of rice husk improved fire retardancy of composites. The addition of maleated anhydride polyethylene did not influence the flammability properties much, except for mass loss rate and specific extinction area. The optimum mixture of rice husk, maleated anhydride polyethylene and linear medium density polyethylene for overall “best” flammability properties of the composites was also determined by multiple response optimisation using the regression models in Design Expert software. The optimum mixture for overall “best” fire retardant properties was found to be 50 wt% of rice husk, 5.6 wt% of maleated anhydride polyethylene and 44.4 wt% of linear medium density polyethylene. The flammability properties measured from composites manufactured with this formulation closely matched the values predicted by the model.

Abstract The effects of rice husk flour (RHF), rice husk biochar (RHB), and rice husk-sludge cake biochar (RH-SCB, expresses sludge cake biochar deriving from a sludge that has been previously conditioned with rice husk) used as physical conditioners on sludge dewaterability were compared. The effects of characteristics of physical conditioners on sludge compressibility and zeta potential were analyzed. The optimal rice husk-based powder was RH-SCB, which presented the highest net sludge solid yield (YN, expresses the dry mass flow by filtration) at 20.39 kg/(m2 h) for 70% dry sludge (DS). Characterization analysis indicates that the hardness and surface Fe content of powders which could influence the compressibility coefficient of sludge cake and sludge zeta potential were the major factors influencing sludge dewaterability. The comparison of feasibility and economic analysis showed that adding RH-SCB improves the quality of the sludge filtrate and reduces the pollution potential of conditioned sludge (the ratio of secondary and primary (RSP) of Cu, Zn, Cd reduces from 43.05, 144.00, 7.25 to 7.89, 14.63, 4.27, respectively), and the costs of using RH-SCB were the lowest (at 88.4% lower than that of the raw sludge). Therefore, it is feasible to use RH-SCB to improve sludge dewaterability.
