膨润土是一种具有广泛的多种用途的防水介质。如果把它和土工织物结合起来,就能够为控制市场的合成膜提供一种具有强竞争力的替代物,这种产物就是一种三层夹心产品,叫“Rawmat”。它有一层粒状膨润土中心层,由纤维素胶结于可生物降解的纤维层和一层土工织物底层之间。这种合成?是通过下列步骤制成的:(1)铺设 Bentonite is a waterproof media with a wide variety of uses. Combining it with geotextiles provides a competitive alternative to synthetic membranes that control the market, a three-layer sandwich product called Rawmat. It has a layer of granular bentonite center layer, made of cellulose glued between the biodegradable fiber layer and a layer of geotextile floor. This synthesis? Is made by the following steps: (1) Laying
