Definitions
- the present invention relates to a method for treating waste glass and a porous body obtained by the method.
- the present invention provides the following waste glass processing method and a porous body obtained by the processing method.
- the method of pulverizing the waste glass there is no particular limitation on the method of pulverizing the waste glass, and for example, a commonly used pulverizing method such as a method of pulverizing using a commercially available industrial mill may be appropriately applied.
- the method of contacting the waste glass with hot steam or hot water under pressure is not particularly limited, as long as the waste glass can be brought into contact with either hot water or hot steam under pressure. Alternatively, hot water and hot steam in equilibrium may be brought into contact at the same time.
- a method of putting water and waste glass in a pressure vessel to a predetermined temperature and pressure, and a method of flowing hot water or hot steam satisfying a predetermined condition through a vessel containing waste glass can be exemplified.
- the contact time between the waste glass and hot steam or hot water can vary depending on the type, amount, size, temperature, pressure, etc. of the waste glass, so an appropriate range may be determined according to the treatment conditions.
- the sodium content of the porous body after the treatment was 1% by mass in terms of sodium oxide, which was significantly lower than that of the glass before the treatment.
- the ratio of calcium oxide increased, it increased relatively due to elution of sodium, which is easily soluble in water.
- porous silicon dioxide was white or translucent before nitric acid post-treatment, it was considered that about 95% of cobalt could be recovered in all processes.
- a waste glass sample was placed in a tubular autoclave and heated so that the temperature near the sample became 380.
- heated water was fed into the autoclave from one end and pressurized to 28 MPa. After about 7 hours, the water was drained, the pressure was returned to normal pressure, and the glass rod was allowed to cool.
