项目摘要

Alumite sludge which is discharged at aluminum sash factories and bagasse which is left over from squeezed sugar cane were used as industrial waste. By mixing these materials with plastic resin and glass fibers, the BMC (Bulk molding compound) composite materials were applied for injection molding and injection compression molding. In terms of the alumite sludge, the mechanical properties were investigated by using γ sludges fired at 900℃ and varying the sludge content of the BMC within the range of 10 to 40%. As a result, it became obvious that the sludge content of 40% attributed for reduction of shrinkage and improvement of mechanical strength because of the loosened bundles and uniform scattering of glass fibers. In the case of the bagasse fibers, the shape of the bagasse changed to needle type after crushing and the fibers contain many cavities inside. These characteristics affected the mechanical strength and quality of product. The cavities in the bagasse work to adjust the viscosity in the BMC and the holes are useful for keeping the glass fibers stationary when being pierced by the bagasse fibers. Therefore, a drastic improvement of the mechanical strength of the product including the bagasse fibers was achieved.From these results, by development of processing technology and heat treatment which can obtain useful properties in terms of the alumite sludge and bagassse, this industrial waste can be converted to useful resources and industrial material for injection molding which can manufacture in large quantities. This research achieved the construction of a manufacturing system for treatment of industrial waste to be used as industrial material.

铝合金门窗厂排放的铝泥和甘蔗压榨后留下的甘蔗渣被用作工业废物。通过将这些材料与塑料树脂和玻璃纤维混合，将BMC（Bulk molding compound）复合材料应用于注射成型和注射压缩成型。以矾土泥为研究对象，采用900℃煅烧的γ泥，在10%~ 40%范围内改变矾土泥含量，研究了水泥基复合材料的力学性能。结果表明，污泥含量为40%时，由于玻璃纤维的松散束和均匀分散，收缩减少，机械强度提高。甘蔗渣纤维粉碎后呈针状，纤维内部有许多空腔。这些特性影响了产品的机械强度和质量。甘蔗渣中的空腔用于调节BMC中的粘度，并且孔可用于在玻璃纤维被甘蔗渣纤维刺穿时保持玻璃纤维静止。因此，包括甘蔗渣纤维的产品的机械强度得到了显著提高。从这些结果来看，通过开发能够获得铝土矿污泥和甘蔗渣的有用性能的加工技术和热处理，可以将这种工业废料转化为有用的资源和工业材料，用于可大量生产的注射成型。本研究实现了将工业废弃物作为工业原料进行处理的制造系统的构建。
