Abstract (en)
The mat for protecting against organic fluid spills has two geo-textile layers between which is packed a layer of an inorganic smektite. This absorbs organic fluids and swells. The protective layer can be improved by adding a proportion of a water absorbing smektite with the ratio between inorganic- and water reactive smektite being betweeen 99:1 to 20:80. The mat can be made of three geo-textile layers with separate layers of smektite. The mat can be made in selected widths with edging which connects to adjacent strips.
Abstract (de)
