广大农村大办沼气,沼气池防水材料必须能就地取材、土法制取才具有普及推广的现实意义。笔者在实践中学习群众经验,收集了部份可用于沼气池上的简易防水材料,兹介绍于下,供沼气池和其他简易构筑物应用参考。 1.沥青渣防水胶泥按如下体积比配成: 废沥青渣:粘土:砂:石灰=1.5:1:0.25:0.25。 The vast majority of rural areas run biogas, and the biogas water-repellent materials must be capable of being locally sourced and soil-based methods have universal significance. In the practice of learning from the masses, the author collected some of the simple waterproof materials that can be used on biogas tanks. I will introduce them here, for the reference of biogas digesters and other simple structures. 1. The asphalt scum waterproof mortar is formulated with the following volume ratio: Waste asphalt slag: clay: sand: lime = 1.5:1:0.25:0.25.
