Abstract:
The invention relates to a method for treating mineral surfaces, said method comprising the following steps, a) the mineral surfaces are treated in order to remove impurities and b) the surface is coated with a plastic material. Said method is characterised in that a transparent, compact hydrophobic polyurethane, which can be produced by reacting i) polyisocyanates with ii) compounds comprising at least two hydrogen atoms for reacting with isocyanate groups, is used as the plastic material in step b).
Abstract:
The invention relates to a device for protecting a coastline, containing at least one porous composite of stone and plastics that is fixed at one point.
Abstract:
The invention relates to a method for stabilising and securing rivers, slopes and embankments and constructions which can be at least partially displaced in water, such as support and construction elements by composite material made from mineral particles, preferably stones, in particular, gravel, and an epoxy resin.
Abstract:
The invention relates to a method for fixing traffic routes, which is characterised in that at least one plastic material is applied to the surface and/or to the inside of the traffic route.
Abstract:
The invention relates to a condensation product obtainable by reacting a1) at least one bicyclic or polycyclic aromatic or heteroaromatic compound, wherein the bicyclic or polycyclic aromatic or heteroaromatic compound is substituted with at least one carboxy group (-COOH), and wherein the carboxy group can be present in salt form, a2) at least one carbonyl compound, a3) optionally at least one sulfonation agent, a4) at least one urea derivative, and a5) optionally at least one further aromatic or heteroaromatic compound, or a physiologically compatible salt thereof.
Abstract:
The invention relates to a system for reclaiming land on coastlines, characterized in that it is composed of arrangements which comprise at least one water-permeable shaped body, wherein the water-permeable shaped body consists of stones which are interconnected by means of polymer.
Abstract:
The invention relates to a porous material containing a substrate that is based on at least one organic polymer A and a coating. According to the invention, i) the organic polymer-based uncoated substrate A is macroporous, ii) the surface of the macroporous substrate is coated with a polymer B based on reactive resins, and iii) said polymer B coating is nanoporous and the average diameter of the nanopores is a maximum 1,000 nm, (recording materials are excluded). The invention also relates to a method for producing the porous material and to the use of said material as filters for gases or liquids. Finally, the invention relates to filters containing the porous material and to a method for filtering gases or liquids.
