Diatom mineral crystal purified granules containing shell powder and preparation method thereof

Abstract

The invention relates to the field of environment-friendly purified materials, in particular to diatom mineral crystal purified granules containing shell powder and a preparation method thereof. The purified granules comprise the following components in parts by mass: 40 to 50 parts of diatomite, 20 to 30 parts of the shell powder, 8 to 16 parts of activated carbon, 12 to 28 parts of attapulgite, 6 to 18 parts of sepiolite, 0 to 10 parts of kaolin, 6 to 8 parts of titanium dioxide, 0 to 0.8 part of anion powder, 8 to 12 parts of quartz sand and 12 to 20 parts of activated metal oxide. The preparation method comprises the following preparation steps: according to the diatom mineral crystal purified granules containing the shell powder, the shell powder and other raw materials are added into the components, so that adsorbing and purifying properties can be greatly improved; the added shell powder can replace the graphene, the stability is improved and the production cost is greatly reduced; and the diatom mineral crystal purified granules containing the shell powder do not need to be insolated for many times during use, so that secondary pollution is avoided.

Description

technical field [0001] The invention relates to the field of environmental protection purification materials, in particular to diatom mineral crystal purification particles containing shell powder and a preparation method thereof. Background technique [0002] Nano-mineral crystals are rare non-metallic minerals given to us by nature, such as sepiolite, attapulgite, and diatomite. They are pore-rich mineral adsorbents. These minerals are formed after reasonable allocation. Nano mineral crystal air purifier products. Its purification and adsorption effect is remarkable, but its stability is poor, and it is easy to release adsorbates when it is exposed to the sun or baked at high temperature, causing pollution.

Problems solved by technology

Its purification and adsorption effect is remarkable, but its stability is poor, and it is easy to release adsorbates when it is exposed to the sun or baked at high temperature, causing pollution. In the prior art, its stability can be greatly improved by adding graphene in the preparation process, but The high price of graphene greatly increases the production cost of the product, which is not conducive to the popularization of technology. Therefore, it is particularly important to invent a kind of purification particles with strong stability and low manufacturing cost.
