近年来,红泥塑料沼气池已经越来越引起人们的关注。这主要是由于红泥塑料具有一些很优异的特性。其最突出的优点有两条:一是它具有很优良的抗光、热老化性能。在模拟自然条件的老化试验箱中,它的寿命要比普通聚氯乙烯塑料高3—5倍。它的预测寿命,在室外自然条件下可达5—10年。二是由于它的原料“红泥”是一种炼铝工业的废弃物,不仅价格便宜,而且利用它制造塑料是变废为宝,有利于消除污染,保 In recent years, red clay plastic biogas digesters have drawn more and more attention. This is mainly due to the red mud plastic has some very good characteristics. Its most prominent advantages are two: First, it has very good anti-light, heat aging properties. Aging chamber in the simulation of natural conditions, its life expectancy than ordinary PVC plastic 3-5 times. It predicts life expectancy in outdoor natural conditions up to 5-10 years. Second, because of its raw materials, “red mud” is a kind of aluminum industry waste, not only cheap, and use it to make plastic is turning waste into treasure, help eliminate pollution, Paul
