20150027498 | Method for Removing Impurities from Shredded Plastic - A method for removing impurities from shredded plastic uses a device having a first and second cleaning disc with a first and second cleaning surface respectively. The cleaning surfaces lie opposite each other and border a cleaning gap between each other. The cleaning discs are rotated and liquid is fed into the cleaning gap. Shredded plastic is fed between the cleaning discs and conveyed through the cleaning gap, and the shredded plastic is processed abrasively by the cleaning surfaces. The temperature difference of the liquid guided through the cleaning gap during entry into the cleaning gap and the temperature of the liquid as it exits the cleaning gap and/or at least one parameter characterizing this temperature difference is measured. The distance between the cleaning surfaces is set such that the measured temperature difference and/or the at least one parameter characterizing this temperature difference achieve a setpoint value. | 01-29-2015 |
20150040946 | Device and Method for Removing Impurities from Shredded Plastic - A device for removing impurities from shredded plastic has a first and second cleaning disk with first and second cleaning surfaces, the cleaning surfaces are opposite each other and delimit a cleaning gap. A drive device rotates the cleaning disks, and shredded plastic is fed between the cleaning disks. The cleaning surfaces have a plurality of cleaning ribs extending between an inner and outer edge of the cleaning surfaces, wherein at least one flank of the cleaning ribs is angled or curved relative to the axial direction of the respective cleaning disk, and a plurality of cleaning bars running transversally to the direction of extension of the cleaning ribs are arranged between at least some cleaning ribs neighboring each other. | 02-12-2015 |
20150352601 | DEVICE AND METHOD FOR REMOVING IMPURITIES FROM SHREDDED PLASTIC - A device for removing impurities from shredded plastic includes at least one first cleaning body having a sectionally tapered and/or cylindrical outer surface forming a first cleaning surface, and at least one second cleaning body having a sectionally tapered and/or cylindrical inner surface forming a second cleaning surface. The second cleaning body accommodates the first cleaning body such that the cleaning surfaces oppose each other and delimit a cleaning gap between each other. A drive apparatus can rotate at least one of the cleaning bodies about its longitudinal axis, and a feed apparatus feeds the shredded plastic into the cleaning gap. The cleaning surfaces each have cleaning ribs, wherein at least one flank of the cleaning ribs is inclined or curved. Cleaning bars running transversally to the direction of extension of the cleaning ribs are arranged between at least some neighboring cleaning ribs. | 12-10-2015 |

20120088860 | ANTIMICROBIALLY EQUIPPED MATERIALS - An antimicrobially treated material comprising a matrix material in which inorganic phosphate salts of at least two different metal cations are contained in finely distributed, dispersed or dissolved form, wherein at least one of the metal cations is selected from copper (Cu) and zinc (Zn). | 04-12-2012 |
20120202902 | FOAMING AGENT FOR PLASTICS - A process for the production of foamed plastic parts, in which a blowing agent composition is introduced into a plastic matrix and causes pore formation in the plastic matrix by releasing at least carbon dioxide gas from the blowing agent composition, wherein the blowing agent composition contains at least one carbon dioxide carrier selected from carbonates, hydrogen carbonates and carbamates of alkali metals, alkaline earth metals, aluminum, transition metals and/or ammonium, and at least one acid carrier. | 08-09-2012 |
20120322923 | FLAME RETARDANT COMPOSITION FOR THERMOPLASTIC MOLDING COMPOUNDS - A halogen-free flame retardant composition that can be incorporated well into different synthetic materials, is easily compatible with the polymer matrix and exhibits good flame protection action, without significantly impairing the mechanical and electrical properties of the synthetic material. The flame retardant composition contains at least one component a) selected from the group of nitrogen bases, melamine derivatives, phosphates, pyrophosphates, polyphosphates, organic and inorganic phosphinates, organic and inorganic phosphonates, and derivatives of the above compounds, and at least one component b) selected from phosphorus-containing polyesters, which can be obtained by reacting phosphorus-containing monomers with each other and/or with ester-forming monomers. | 12-20-2012 |
20130065979 | LASER-INDUCED PLASTIC FOAMING - A matrix material composed of polymer, preferably of thermoplastic polymer, or coating material. The matrix material includes 0.01 to 50% by weight of an additive for foaming of the matrix material which can be triggered by irradiation with laser light or IR light. The additive includes at least the following constituents: a) at least one absorber material which, embedded or dissolved in the matrix material, absorbs laser light or IR light and brings about local heating in the matrix material at the site of irradiation with laser light or IR light, and b) at least one blowing agent which, when heated due to the irradiation with laser light or IR light to temperatures above 50° C., forms a gas which foams the matrix material by decomposition, chemical conversion or reaction. | 03-14-2013 |
