【摘要】 粉煤灰和赤泥分别是热电厂和氧化铝厂排放出来的废渣。为充分利用这些废渣,我们研究了赤泥/粉煤灰复合填料填充PVC。实验表明:赤泥可改善A—PVC的成型加工性能,缩短塑化时间,提高材料的抗张强度。赤泥/粉煤灰复合填料改性PVC可降低PVC制品的成本。更多还原

【Abstract】 Coal dust and red mud are fag-end taken off from power plants and alumina factories respectively.We have developed composite fillers of coal dust and red mud for PVC to take good use of the fag-end.The experiment shows that red mud improves proceessability of APVC (PVC modified by coal dust), reduces plasticizing time, increases the tensile strength of the material. The composite fillers of red mud/coal dust lower down the cost of PVC products.更多还原
