Abstract
Support material from porous ceramic granulate, produced from a mixture of 45 to 80 parts by weight clay, 0 to 50 parts by weight calcite, quartz sand, dolomite, feldspar, chamotte and/or sepiolite, 15 to 30 parts by weight water, 0.01 to 0.03 parts by weight deflocculant, 0.001 to 0.01 parts by weight surfact and optionally agents counteracting the deflocculant and foamed under an overpressure of at least 0.3 bar prior to baking and filled or charged with at least one volatile substance.
Claims10
Support material of porous ceramic granulate produced from a mixture of 45 to 80 parts by weight clay, 0 to 50 parts by weight calcite, quartz sand, dolomite, feldspar, chamotte and/or spiolite, 15 to 30 parts by weight water, 0.01 to 0.03 parts by weight deflocculant, 0.001 to 0.1 parts by weight surfactant and optionally agents counteracting the deflocculant and which was foamed under an overpressure of at lest 0.3 bar prior to baking and filled with at least one volatile substance.
Method for the manufacture of support material according to one of the preceding claims, characterized in that the volatile substances are applied to the support material in a composition containing 10 to 90 wt. % of volatile substance, up to 15% surfactant and up to 70% water.
Use of support material manufactured according to the method of the preceding claims as an air freshener.
Use of support material manufactured according to a method according to the preceding claims for improving the odour emitted by refuse or biological waste collecting containers.
Use of the support material manufacture according to a method of the preceding claims as an additive to compost.
