Problems solved by technology

[0020] In order to solve the problem of scattering and floating of adsorbed powder that occurred when it was used for environmental pollution measures in the soil and water environment, the present invention provides adsorption molding of harmful substances that have been processed so that the adsorbed powder does not scatter and float. body, and in the polluted environment where the harmful substance adsorption formed body is applied, the harmful substance accumulated in the environment is captured and adsorbed by the harmful substance adsorbent of the harmful substance adsorption formed body, and is suspended in the environment, and prevents the pollution of the environment. Infiltration or diffusion in other places

Embodiment 1

[0061] figure 1An example is shown as a harmful substance-adsorbing water-soluble sheet in which at least an adsorbent that adsorbs a powder of harmful substances is contained and attached to the surface of a flexible water-soluble sheet. (a) is a schematic oblique view of one harmful substance-adsorbing water-soluble sheet, and (b) is a cross-sectional view along line X-X. During production, knead a compound containing at least a powder adsorbent for adsorbing harmful substances and a binder to prepare a kneaded product, and attach the kneaded product to the surface of the water-soluble sheet 1 to make a harmful substance adsorbing agent. Water-soluble tablets1.

[0062] Here, in order to mix well with the soil, the powder adsorbent for adsorbing harmful substances contains 20 g / m2 or more fine powder, and it is desirable to have the following fine powder specifications, that is, the particle size has a particle size of 200 mesh, At the same time, its particle density is a...

Embodiment 2

[0091] [Table 1]

[0092] .

[0093] In the present invention, as an example of a disintegration-controllable multifunctional absorbent tablet for obtaining a hazardous substance-adsorbing tablet that can freely design the optimum mode of adsorption performance or disintegration-dispersion performance, the most ideal one is a tablet for use with an adsorbent. Fine powdered activated carbon with a specific surface area of ​​800 m2 / g or more and an average particle size of 100 μm or less with a specific gravity of 50% or less of the agent weight, a combination of crystalline cellulose and silica as a powder mixture with a specific gravity of 1 or more, as an example at this time, It demonstrates below using Table 1.

[0094] Table 1 above shows the comparison results of tablet formability, disintegration time in soil, disintegration and dispersion state in water, and buoyancy state of the tablet when the mixing ratio of the adsorbent and the powders added in combination is ch...

Abstract

To provide a formed body, in the form of a water soluble sheet or tablet, that is adapted to be applied to a polluted environment without causing scattering of fine powder, formation of dust and necessitating much labor and that is a hazardous substance adsorbing formed body which has multi-functions including a hazardous substance adsorbing function and which is capable of adsorbing and fixing hazardous substances when applied to the polluted environment. A hazardous substance adsorbing formed body which is capable of adsorbing and fixing hazardous substances in a polluted environment such as soil and which contains a powder adsorbent as one of plural ingredients used as a raw material for forming the formed body, the adsorbent being a porous fine powder which contains 200 mesh pass particles and has a particle density, in terms of average particle size, of 100 [mu]m or less, where a proportion of the 200 mesh pass particles is more than 80% by weight. In addition to the adsorbent, an additive for imparting other functions is optionally incorporated.

Description

technical field [0001] The present invention relates to a harmful substance adsorbing molded body capable of eliminating soil pollution in fields, paddy fields, rivers, groundwater, lakes, and the like. More specifically, the present invention relates to a harmful substance-adsorbing molded body, which is based on the premise that the harmful substance-adsorbing molded body formed with a binder is an adsorbent that adsorbs powder of harmful substances from a soil or water polluted environment. The hazardous substance-adsorbing powder is included in one of the blanks used in the manufacture of the aforementioned harmful-substance-adsorbing molded body, and is embodied from the viewpoint of its particle form. , and whose particle density is less than 100 μm in average particle size, and whose proportion exceeds 80% of the weight of the particle size, the powder is used to impart other functions in addition to the binder and the harmful substance adsorption powder It is prepared...
