沼气池新型气密复合材料的试验研究

STUDIES ON A NEW AIRTIGHT COMPOSITE MATERIAL FOR DIGESTERS

本文对以硅灰石纤维增强水泥为基层,聚合物胶乳水泥为表层的沼气池新型气密复合材料的性能、施工、气密效果及气密机理进行了研究。试验证明:硅灰石纤维有很强的耐碱性,对水泥有明显的增强效果。研究出的沼气池气密复合材料价格便宜、气密效果十分显著,可大幅度提高沼气收集率。

This paper deals with the properties, the construction, the airtightness and the mechanism of a new composite material used for digesters. The results show that wollastonite fibre is highly alkali resistant and its reinforcing effect on cement is great. It is found that the airtight composite material for digesters prepared in our research is cheap in price and obviously high in airtightness. By using this composite material, the collection ratio of methane can be greatly promoted.
