The invention discloses an attapulgite argil powder with an air purifying function. The technical scheme is as follows: the attapulgite argil powder with an air purifying function is prepared from high-viscosity attapulgite clay, an attapulgite constant-humidity conditioner, a natural mineral adsorbing / filtering agent, Cacumen Biotae, aluminum silicate fiber and polyacrylamide. The attapulgite argil powder is prepared by the following steps: pulverizing the materials, soaking and aging to obtain a wet mixture, extruding the wet mixture into a strip, airing the strip, pulverizing to obtain powder, and packaging to obtain the finished product. The attapulgite argil powder has favorable cohesive property, plasticity, thixotropy, fire resistance and thermal stability; the pottery prepared from the attapulgite argil powder with an air purifying function contains a great deal of micropores and activated carbon, thus, has the characteristics of low shrinkage, no cracking or deformation and favorable adsorbability, and can effectively adsorb formaldehyde, ammonia, benzene and other harmful substances in the air, thereby protecting the environment and improving good health of people. The invention is suitable for producing pottery artware with an air purifying function.

The invention discloses a construction site foundation pit protective fence with good warning effect, which comprises a frame body, and a plurality of railings are welded inside the frame body; The bottom is fixedly connected with two springs, and the inner top of the strip groove is fixedly connected with a glass sleeve and a rubber sleeve. Both the glass sleeve and the rubber sleeve are slidably connected with iron sliders. The glass The outer walls of the sleeve and the rubber sleeve are slidably connected with a magnetic wiper ring, wherein the side wall of the magnetic slider located in the glass sleeve is provided with a chemical fiber layer, and the side wall of the magnetic slider located in the rubber sleeve is provided with a fur layer . The present invention discharges through two matching conductive needle tips, and makes the neon gas in the square cavity energized to emit eye-catching red light, so that a good warning effect can be provided during night construction, and vehicles can be prevented from colliding with the protective fence when driving at night Breaking into the construction site can lead to dangerous situations.

The invention discloses an air purification material and a preparation method thereof. The air purification material comprises a honeycomb type filter screen and a purification composition filled in the honeycomb type filter screen, wherein the purification composition is prepared from the following raw materials: samarium sulfide, bismuth vanadate, ferrous tungstate, diatomite, activated attapulgite, hafnium hydroxide, lithium metaaluminate, ferric oxide, chitosan fiber, tauroursodeoxycholic acid sodium salt, oxidized graphene, coconut shell powder, negative ions powder, leaf mold, polyvinyl alcohol and deionized water. The filtering rate of PM2.5 is up to 99.2% through the air purification material, the purification efficiency of formaldehyde and benzene harmful gases are respectively up to 95.3% and 92.7% and above, the air is effectively purified, and the air environment can be obviously improved. The air purification material has good breathability, as well as air purification function, and is very suitable for large-batch production and application.

The invention discloses a production method for a plant multi-fiber modified board with an air purifying function. The production method is characterized in that multiple plant fibers are extracted and mixed according to the proportion, water is added to the plant fibers, the plant fibers are made into anion pulp, then modified cationic starch is added, the plant fibers are rearranged by polymerizing zwitterions, a coarse cotton cloth sizing agent flowing mode is used for dehydration so that a wet fiberboard can be formed, then purifying structure films doped with nanometer titanium dioxide are formed in the surfaces of wet fibers, rolled, pressurized and laminated to be manufactured into the wet fiberboard of the needed thickness, and finally the wet fiberboard is dried. The purifying films can decompose harmful substances such as formaldehyde and methylbenzene under light condition. The wet fiberboard can be modeled at will, and can be made into boards with different physical properties; continuous forming is adopted in the production process, and the yield is high; selected raw materials are wide, most raw materials are abandoned materials, and resources are saved; the different fibers are combined through hydrogen bonds, harmful ingredients are avoided, and the board is environmentally friendly.
