Definitions
- the invention relates to a method for absorbing pollutants, in particular aldehydes, volatile organic compounds (VOC) and odors, and for permanently protecting in particular the room air from these pollutants.
- pollutants in particular aldehydes, volatile organic compounds (VOC) and odors
- the object of the present invention is to propose a method which enables a permanent removal of pollutants.
- This object is achieved in that a protein-reactive substance is provided at least in the vicinity of pollutant emitters or potential pollutant emitters.
- Protein hydrolysates and particularly enzymatically degraded skieroproteins have proven to be particularly advantageous in achieving the object of the invention.
- the protein-reactive substance is used in liquid, pasty, viscous or pulverulent form.
- the protein-reactive substance can be adapted particularly well to the male pollutants.
- Another very advantageous embodiment of the invention is also that the protein-reactive substance is spray-dried before use.
- a likewise very advantageous embodiment of the method according to the invention is also present when the protein-reactive substance is applied to a carrier, an article, a coating, a coating system or the like.
- the protein-reactive substance is incorporated in a carrier, an article, a coating or the like.
- the protein-reactive substance can also attach very easily afterwards.
- the protein-reactive substance is provided in impregnating agents and / or fiber coatings, in particular for textiles or the like.
- the protein-reactive substance is used in wall, ceiling and / or floor coverings.
- the method according to the invention offers a permanent solution which not only prevents emission of pollutants from the objects treated with this solution, but also absorbs any nevertheless escaped pollutants from the ambient air.
- a protein-reactive substance preferably in the form of an aqueous protein hydrolyzate solution, is applied to the wood chips during the production of the plates. After the excess moisture has dried off, a thin film of the protein-reactive substance remains on the surface of the wood chips.
- This protein-reactive substance absorbs directly from the wood chips exuding pollutants. There are sufficient reactants in the form of amino acid residues available that allow the pollutants to react, so that they are chemically bonded in the protein-reactive substance.
- this thin film of the protein-reactive substance is an effective diffusion barrier for the pollutants, so that they in no case from the pollutants
- the thin film is usually extremely elastic and thus also withstands mechanical stresses.
- the protein-reactive substance is applied later or is mixed in a binder for the plates to be formed.
- the protein-reactive substance it is also conceivable for the protein-reactive substance to be embedded in paints, lacquers, mordants, wood preservatives, coatings, synthetic resins, in particular synthetic resin coatings, plasters or the like, so that the same protective effect as already described can be achieved during application. In addition, it is then possible to treat wall and floor coverings after their installation.
- the protein-reactive substance is used in plasterboard or gypsum fiber boards but also in cleaning and other coatings.
- the protein-reactive substance cleaning agents and detergents is added, whereby a protective layer is applied or renewed with each cleaning.
- enzymes contained in detergents and cleaning agents are modified in such a way that they can likewise be employed as a protein-reactive substance.
- enzymes contained in detergents and cleaning agents for example proteases, lipases, amylases
- enzymes contained in detergents and cleaning agents are modified in such a way that they can likewise be employed as a protein-reactive substance.
- enzymes contained in detergents and cleaning agents for example proteases, lipases, amylases
- T ⁇ DATENYWORD ⁇ SON ⁇ Sj ⁇ Sj03 ⁇ Sj03PCTB odt remaining non-active site amino acid residues are used to capture and degrade pollutants.
- these amino acid residues can be modified so that the pollutant degradation allows or is significantly improved.
- Such enzymes then have on the one hand the conventional properties and now additionally the function of pollutant absorption and pollutant degradation.
- textile materials or papers can be provided with the protein-reactive substance, which also vapor barriers, wallpaper or the like can be used simultaneously for pollutant and / or odor removal.
- the protein-reactive substance can be used in liquid form, as a powder, paste or in aqueous solution.
- the choice of the respective dosage form is essentially dependent on the respective application.
- a powder can be obtained by spray-drying the liquid form.
- the protein-reactive substance can thus be used in a wide variety of ways. It is conceivable, for example, that a selective coating of either single or multiple layers of a composite material or certain individual parts of a composite material, such as chips, veneers, films or the like is made.
- the protein-reactive substance can be doped with other substances such as urea, zeolites, certain preservatives or the like, whereby the receptivity to certain pollutants / odors can be influenced and adjusted.
- the concentration of this doping depends on the one hand on the concentration of pollutants occurring and on the other hand on the pollutant group.
- the protein-reactive substance can be made more or less sticky.
- Sticky equipment can be produced by long chains of molecules.
- the pollutants or odors are adsorbed by the protein-reactive substance, that is, reversibly bound, i.e., physisorbed and absorbed in a further reaction step, i. chemisorbed, that means reacted at corresponding reactants of the reactive substance and bound.
- the Abreagieren is a process that takes much longer compared to the adsorption, so that initially takes place an overlay between the two processes.
- delivery of the adsorbed pollutant / odor molecules essentially does not take place because absorption also takes place immediately, so that there is no time for the re-release of the adsorbed molecules.
