【摘要】 本文研究了超细粉煤灰填充酚醛,聚氯乙烯塑料后的性能变化,及填充无补强丁苯胶后性能的分析。发现粉煤灰可作酚醛,聚氯乙烯的填充剂。不适于作丁苯胶的补强剂。在同样的填充条件下,粉煤灰的粒径越细,填充效果越好。其中粉煤灰-酚醛填充材料可达到日用模塑粉的国家标准,粉煤灰-聚氯乙烯填充材料可达到钙塑材料的企业标准,而材料成本有所降低,同时有助于消除环境污染。更多还原

【Abstract】 This paper dealt mainly with the work on the properties of SBR, PVC and PF filled with the superfine pulverized fuel ash. It was found that the fuel ash can not be used as a filler for SBR, because the main properties, such as tensile strength, elongation at break, tear strength and so on, of SBR filled with the fuel ash were poorer than those of the material filled with super fine calcium carbonate, but the other properties, such as hardness, modulus and permant set, were similar to those.The properties, such as flexural strength and impact strength, of PF filled with the fuel ash were up to the state standards of the moulding powder for daily use, but its electrical properties came down, so that it can not be use for electric products. When PVC was filled with the fuel ash, its properties, such as tensile strength, flekurol strength, impact strength, Martens heat resistance and so on, were up to the business standards of CaC08-PVC. The experimental results under the same filling conditions showed that the finer the particle size of pulverized fuel ash, the better the performance of the material filled with the fuel ash.If the fuel ash is used as a filler for a material, cost of the material will be reduced, and in this way the enrironment pollution from fuel ash will be eliminatet. Therefore, it is valuable to our industry.更多还原
