Problems solved by technology
However, there are two problems in this kind of block activated carbon: one is to form a multi-purpose resin binder, and the adsorption capacity of activated carbon is greatly reduced.
Second, the harmful substances adsorbed by activated carbon are difficult to decompose by themselves, and the air purification ability is significantly reduced after adsorption saturation
However, the range of photocatalytic reactions produced by photocatalysts is also very limited, and the free hydroxyl groups and active oxygen produced have no adsorption effect, and can only passively wait for the arrival of harmful substances and bacteria and viruses, so a large area is required to obtain purification The effect of air, so the cost is high, it is difficult to popularize
In addition, in recent years, studies have suggested that ultraviolet rays and free hydroxyl groups in the environment are also corrosive to humans, so the large-scale use of photocatalysts has also been questioned

Embodiment Construction
[0014] The first embodiment: adopt the following six steps.
[0015] 1. Screening: Pass 50-85 parts of activated carbon powder above 200 mesh, 15-50 parts of kaolin clay of 800-1000 mesh, and 1.5-15 parts of adhesive through a vibrating sieve above 60 mesh to remove impurities.
[0016] 2. Mixing: Put the sieved raw materials into the dry powder mixer and mix them well.
[0017] 3. Kneading: Put the mixed material into the mixing machine, gradually add water with 70-85% of the weight of the material, and knead the material for 20-30 minutes.
[0018] 4. Mud aging: Put the mixed material into the mud mixer and knead the mud repeatedly for 2-3 times, wrap the extruded mud section with plastic cloth, seal and stale for 24-48 hours; put the stale mud section again Put the mud in the mud refiner for 2 times, and at the same time pump out the air in the mud to make the vacuum degree above 0.04Mpa, then extrude from the mud refiner outlet and wrap it with plastic cloth for use.

The invention relates to an air purification product and a preparation method thereof, namely cellular activated carbon with a self-cleaning function and a preparation method thereof. The cellular activated carbon with the self-cleaning function is blocky activated carbon with through-holes, and is characterized in that the activated carbon block is prepared from the following components by weight: 50 to 85 parts of activated carbon, 15 to 50 parts of kaolin, 1.5 to 15 parts of inorganic adhesive and 0.5 to 1 part of photocatalyst by mixing, proportioning, mud refining, staleness, extrusion forming and other working procedures. The photocatalyst is added to the cellular activated carbon block, and formaldehyde, benzene, bacteria, virus and other harmful substances adsorbed by the activatedcarbon can be respectively oxidized and decomposed into innocuous substances to be emitted outside by strong oxidizer prepared by the photocatalyst in lighting condition; and therefore the active adsorption of the activated carbon and the passive decomposition of the photocatalyst are skillfully combined, thereby forming complementary advantages and greatly and even indefinitely prolonging the service life of the cellular activated carbon block.
Description
technical field [0001] The invention relates to an air purification product and a production method thereof, that is, a honeycomb activated carbon with self-cleaning function and a production method thereof. Background technique [0002] As we all know, activated carbon has a strong adsorption effect and can be used for the purification of air, water and other substances. Therefore, some people put activated carbon indoors, hoping to improve indoor air quality. Activated carbon is mostly very fine powder, and it needs to be packed in a container when used indoors. The container has a certain hindering effect on the contact between air and activated carbon. In order to solve this problem, someone has developed honeycomb activated carbon, that is, activated carbon is made into a porous block. However, there are two problems in this kind of block activated carbon: one is to form a multi-purpose resin binder, and the adsorption capacity of activated carbon is greatly reduced. ...
