A water absorption treatment material includes a first grain and a second grain that absorb a liquid. The first grain includes a first core portion and a first coating portion. The first core portion has a grain-like shape. The first coating portion contains an adhesive material, and covers the first core portion. The second grain includes a second core portion and a second coating portion. The second core portion has a grain-like shape. The second coating portion contains an adhesive material, and covers the second core portion. The thickness of the second coating portion is smaller than the thickness of the first coating portion.

A separation membrane complex includes a porous support, a dense part covering one surface of the support from a boundary position toward one side in a predetermined direction on the surface, and a separation membrane covering the surface from the boundary position toward the other side and covering the dense part in the vicinity of the boundary position. In a case where, in a cross section, within a specified range from the boundary position toward the one side in the predetermined direction up to 30 μm, a maximum angle among angles formed of the surface and lines connecting respective positions on a surface of the dense part on a side of the separation membrane and the boundary position is acquired as an evaluation angle, a maximum value of four evaluation angles at four measurement positions is not smaller than 5 degrees and not larger than 45 degrees.

Methods of manufacturing a substrate including a component, such as superabsorbent material, having a volatile hydrophobic coating are disclosed. The method can include providing a fluid supply including a liquid and providing a supply of the component. The component can include a volatile hydrophobic coating. The method can include introducing the component to the fluid supply. The method can also include transferring the component in the fluid supply to provide the substrate. The method can further include applying heat to the substrate. The heat can remove the volatile hydrophobic coating from the component.

The filter medium, composed of a wet-laid nonwoven fabric including a glass fiber, for air filters according to the present disclosure includes a cationic binder resin, a fluororesin, and a cationic surfactant, and the solid content mass ratio of the fluororesin to the cationic surfactant is within a range of 30/70 to 80/20.

The present invention relates to a synthetic filter material comprising grit, one or more oxides or hydroxides of Fe, La and/or Al, cement, fast-setting binder and water, which can serve as filter material for soil filters for phosphate adsorption, and to a process for producing the filter material.

The invention discloses a core-shell structure polymer magnetic nanosphere with a high Cr (VI) adsorption capacity and its preparation method and application. The preparation method includes: adding Fe.sub.3O.sub.4 powder into a mixed solution of water and ethanol, dispersing Fe.sub.3O.sub.4 powder in the solution evenly by ultrasound, sequentially adding resorcinol and formaldehyde into the suspension to adjust a pH, stirring and reacting to obtain Fe.sub.3O.sub.4@RF evenly dispersed in a chitosan solution, dropwise adding the prepared suspension into a mixed solution of paraffin and span 80, stirring for a period of time, adding a glutaraldehyde aqueous solution, stirring and reacting to obtain a magnetic chitosan nanosphere. The magnetic chitosan nanosphere prepared may be applied to adsorbing Cr (VI) in a water solution. Not only the magnetic chitosan nanospheres prepared has a high adsorption capacity for Cr (VI), but also can be quickly separated by an external magnetic field after adsorption.
