20160129419 | WATER ABSORBING MATERIAL AND MANUFACTURING METHOD THEREOF - A water absorbing material which can reduce burden on the environment in disposal and can be manufactured at low cost, and a manufacturing method thereof are provided. The water absorbing material contains paper obtained by separating polyvinyl chloride from vinyl chloride wallpaper as a raw material. | 05-12-2016 |
20160115292 | SEPARATION METHOD AND SEPARATION DEVICE USED THEREIN - Provided are a separation method and a separation device used therein with which plastic and aluminum can be separated. The separation method includes a first heating step, and a first heat insulation step. In the first heating step, a processing target, which is accommodated in a container and contains aluminum and one or more types of plastic, is heated to a first temperature. The first temperature is a temperature that is less than the melting point of the aluminum and is greater than or equal to the melting point of at least one type of the plastic. Thus, the at least one type of plastic is melted. In the subsequent first heat insulation step, the processing target is kept at the first temperature. The heat insulation is continued until the aluminum is precipitated in the container and separated from the melted plastic. | 04-28-2016 |
20160082623 | SEPARATION DEVICE AND SEPARATION METHOD - Provided are a separation device and a separation method with which plastic and aluminum can be separated. A separation device includes a heating unit, a container, and a pressing member. The heating unit heats a processing target containing aluminum and one or more types of plastic to a first temperature. The first temperature is a temperature that is less than the melting point of aluminum and is greater than or equal to the melting point of at least one type of plastic. The container is for accommodating the processing target heated by the heating unit to the first temperature. The pressing member has a hole portion allowing the plastic melted by the heating unit to pass through, and separates aluminum and the plastic by pressing the processing target accommodated in the container. | 03-24-2016 |
20150360203 | WATER ABSORBING MATERIAL AND MANUFACTURING METHOD THEREOF - A water absorbing material includes a granular core portion and a coating layer portion. The coating layer portion covers the granular core portion. The coating layer portion contains fluff pulp and a water-absorbent polymer. These fluff pulp and water-absorbent polymer are both derived from a sanitary article. | 12-17-2015 |
20150360202 | WATER ABSORBING MATERIAL AND MANUFACTURING METHOD THEREOF - A water absorbing material contains paper powder obtained by separating gypsum from a gypsum board as its raw material. The weight ratio of the gypsum adhering to the paper powder with respect to the paper powder is 5% or less. | 12-17-2015 |
20150360200 | WATER ABSORBING MATERIAL AND MANUFACTURING METHOD THEREOF - A water absorbing material contains a water-absorbent material consisting of at least one of plastic and fluff pulp that are obtained by separating a water-absorbent polymer from a sanitary article containing the plastic, the fluff pulp and the water-absorbent polymer. The weight ratio of the water-absorbent polymer adhering to the water-absorbent material with respect to the water-absorbent material is 3% or less. | 12-17-2015 |
20120288955 | WATER ABSORBING MATERIAL - Provided is a water absorbing material having a granular core portion and a coating layer portion coating the granular core portion, which enables a test result after use to be clearly determined by developing vivid and uniform color. In the water absorbing material, the coating layer portion is composed of 90 wt % to 96 wt % of a substrate and 10 wt % to 4 wt % of an excretion test material, the excretion test material contains a porous adsorbent having an adsorbance of 20 wt % or greater and including micropores, and an excretion test indicator adsorbed on the micropores of the porous adsorbent, and the excretion test indicator is added in an amount more than 0.1 wt % and not more than 1.0 wt % relative to the total amount of the coating layer portion. | 11-15-2012 |
20120230884 | WATER ABSORBING MATERIAL AND MANUFACTURING METHOD THEREFOR - Provided is a water absorbing material having a granular core portion and a coating layer portion coating the granular core portion, which does not produce color before use and with which a test result can be determined only after use. In the water absorbing material, the coating layer portion is composed of 90 wt % to 96 wt % of a substrate and 10 wt % to 4 wt % of an excretion test material, the excretion test material contains a porous adsorbent having an adsorbance of 25 wt % or greater and including micropores, and an excretion test indicator adsorbed on the micropores of the porous adsorbent, and the excretion test indicator is added in an amount in the range of 0.015 wt % to 0.10 wt % relative to the total amount of the coating layer portion. | 09-13-2012 |
