    • A cover composition that can be applied to a bulk material pile, such as landfill refuse, to protect the pile from wind, precipitation, and access by animals and insects is provided. The cover composition is a mixture of a liquid, typically, water; bentonite clay; and synthetic fibers. The composition may be enhanced by the addition of one or more of the following additives: Portland cement, pregelatinized wheat starch, synthetic polymers, soda ash, and latex paint. Unlike prior art cover compositions, the disclosed composition adheres well to waste material, most notably plastics, whereby the composition is easy to apply and provides a substantially uniform, durable protective cover to landfill refuse piles and other bulk materials. Methods of applying the composition to bulk material piles are also disclosed.
    • 提供了可以应用于散堆物料堆的垃圾掩埋物组合物,例如垃圾填埋场垃圾,以保护桩免受风,沉淀和通过动物和昆虫的进入。 覆盖组合物是液体,通常为水的混合物; 膨润土 和合成纤维。 可以通过加入一种或多种以下添加剂来增强组合物:波特兰水泥,预胶化小麦淀粉,合成聚合物,苏打灰和乳胶漆。 不同于现有技术的覆盖组合物,所公开的组合物很好地粘附到废料上,特别是塑料,由此组合物易于施用,并且为填埋垃圾堆和其他散装材料提供基本上均匀的,耐久的保护盖。 还公开了将组合物施用于散装材料堆的方法。
