Composites of waste polyethylene (WPE), collected from municipal solid waste/recycled waste rubber powder (RWRP) reactive compatibilizing agent, maleic anhydride (MA) and glass fiber (GF) up to 20 wt%, prepared by melting and irradiated with gamma-rays up to 150 kGy have been studied. Tensile strength (TS), elongation at break (Eb), elastic modulus, hardness, thermal and morphological parameters of the irradiated composites were investigated. The examined mechanical properties have been found to improve largely with filler content. Interesting Eb behavior has been detected for the irradiated composites loaded up to ∼10 wt% GF and has been basically discussed in view of matrix crystallinity and morphology. TGA thermograms of unirradiated composites revealed enhanced thermal stability than that reported for the blend whereas comparatively slight improvement has been demonstrated by irradiation. Whereby insignificant alteration in Tm values was observed by loading or irradiation, yet ΔHm maximum of 3.41 J/g, indicated for the 5 wt% GF irradiated composite with an integral dose of 75 kGy, emphasizes the influence of the relatively moderate load and dose levels on matrix stability. The phenomenon has been confirmed by the respective SEM micrographs. 相似文献

燃气锅炉烟气余热回收实验分析 总被引:10,自引:2,他引:8
通常燃气锅炉的排烟温度较高 ,一般在 16 0~ 2 4 0℃。所排烟气中含有不凝结气体和水蒸气 ,过热状态的水蒸气是烟气中热量的主要携带者。文章分析了烟气成分、换热机理 ,通过实验证明了降低锅炉的排烟温度回收烟气中水蒸气的显热和潜热 ,不仅提高了锅炉的热效率 ,同时凝结液也回收了烟气中部分酸性气体 ,因此具有节能与环保的双重功效 相似文献
