Abstract

The invention provides an alga-calcium-mineral air purification medium. The air purification medium is mainly prepared from, by weight, 42-48.44 parts of alga mineral powder, 4.2-9.8 parts of calcium powder, 0.8-1.2 parts of catalysis powder, 2.4-3.0 parts of mineral modifiers, 36-48 parts of liquid-phase media and 1.5-1.8 parts of photocatalyst. The raw materials are subjected to pre-stirring, hole forming and granulating, polishing and oxidation, primary drying, photocatalyst surface treatment and secondary drying to form particle medium carriers. The air purification medium has the advantages that the absorption-catalysis-purification performance is outstanding, the preparation process is mild and free of rigorous requirements, product application is flexible, and an air purification device with de-odoring, deodorization, taste removal or bacteria resistance and mildew-proof functions by applying appropriate matched application components.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an algal calcium mineral air purification medium and a preparation method and application thereof. Background technique [0002] On August 13, 2015, a research report published by American scientist Robert Rhodes showed that air pollution in China would cause an average of 4,000 deaths per day, accounting for 17% of the total death toll in China. In 2014, the China Building Decoration Association released the "Report on Home Environment and Interior Decoration", which showed that the average rate of formaldehyde exceeding the standard was 70% to 80%, and the highest detection value exceeded the national standard by 4.2 times. There are more than 300 pollutants that can be detected indoors, including more than 20 carcinogens. Due to the slow release of various indoor building decoration materials and household continuous potential harmful pollution sources, the indoor air...
