Activated carbon air purifying plate

Abstract

The invention discloses an activated carbon air purifying plate. The prescription comprises the following raw materials in percentage by weight: 15-50 percent of powdered activated carbon, 10-40 percent of expanded perlite, 0.05-2 percent of organic silicon water repellent and 30-45 percent of adhesive, wherein the organic silicon water repellent can not be added before die compression and is sprayed on the surface after being discharged out of a drying chamber, and the ratio of the organic silicon water repellent and water is 1:7-12 during spray. The activated carbon air purifying plate is prepared by the following steps of: uniformly mixing and stirring the adhesive and the organic silicon water repellent; uniformly mixing with the expanded perlite; adding the powdered activated carbon to be uniformly stirred; screening mixed raw materials, wherein the specification of a screen is 0.8-1.5mm; compressing the screened materials into a die to form a blank at the pressure of 5-25MPa; naturally drying a moulded blank; grinding, trimming, engraving, tinting and drying the moulded blank; and packaging after normal temperature. The invention combines the decoration and the air purifying function, beautifies the environment, purifies indoor air, adsorbs sound and preserves the temperature without occupying indoor space.

Description

Technical field [0001] The invention relates to an activated carbon building decoration board, in particular to an activated carbon air purification board. Background technique [0002] Activated carbon is a kind of black powdery, granular or pellet-shaped amorphous carbon with porous, the main component is carbon, and also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It also has a fine structure like graphite, but the crystal grains are small and the layers are stacked irregularly. It has a large surface area (500~1000m2 / g) and strong adsorption performance, which can adsorb gas, liquid or colloidal solid on its surface; for gas and liquid, the quality of the adsorbed material can be close to that of activated carbon The quality of itself. Its adsorption is selective, and non-polar substances are easier to adsorb than polar substances. In the same series of substances, the higher the boiling point, the easier it is to be adsorbed, the higher th...
