資料は何もない。2. Description of the Related Art Conventionally, when treating a used waste fluorescent lamp, the waste fluorescent lamp is crushed and wet-processed by washing with a cleaning solution containing a chelate or the like, or a base portion is removed.
There has been a method in which an airflow is introduced into the crushed waste fluorescent lamp glass to remove the phosphor. However, in the above-mentioned wet treatment, since the phosphor is fine, the purity of the phosphor is reduced by filtration, drying, and washing, and it is difficult to reuse the phosphor. In addition, there is no known material about vacuum suction or blowing air into the glass body of a waste fluorescent lamp to blow glass fine powder, phosphor, mercury, and the like, and to reuse the recovered phosphor.

り、蛍光体としての使用を考える方が良い。However, there is a possibility that the fluorescent materials of each company may differ from those of recovering rare earth elements from the fluorescent materials and reusing them for fluorescent lamps. Therefore, it is better to consider its use as a phosphor than to consider the recovery of rare earths.

状のガラスバルブを円形にベンディングする。The first problem when reusing as a phosphor is mixing of coarse particles. JP-A-6-4
According to the prior art of 9445 Fluorescent lamp coating solution, a generally annular fluorescent lamp is manufactured as follows. A coating solution for a fluorescent lamp is prepared by suspending a phosphor and a binder in a high-viscosity solution in which a binder is dissolved in a solvent. Pour the fluorescent lamp coating liquid into the inner surface of the glass bulb,
Apply and dry uniformly. Thereafter, the phosphor is baked at a temperature of 400 ° C. or more to adhere the phosphor to the inner surface of the glass bulb. The glass bulb is heated to a temperature of 600 ° C. or more, and the straight glass bulb is bent in a circular shape.

光体に混入する、粗粒子はガラス等の外部からの混入物
が大部分と考えられる。JP-A-6-49445 The coating solution for a fluorescent lamp has a binder containing a water-soluble rare earth compound, boric acid and colloidal alumina. The crystal form of the binder such as colloidal alumina is changed by heating, and the phosphor is fixed to the glass bulb. These binders do not have a strong binding power to the phosphors, and the phosphors fall apart upon pulverization. Further, compared with the phosphor, the amount of the binder remaining after the heating is small, and there is no bad influence on the fluorescent lamp. Therefore, it is considered that most of the coarse particles mixed into the phosphor are foreign substances such as glass.

にある。The glass and phosphor (including a mercury compound) according to the first and second aspects of the present invention are processed by a pulverizer using balls or media such as a ball mill, a tube mill, a vibration mill or a barrel grinder. This is to prevent the glass from being ground to the particle size of the phosphor. Actually, the glass is crushed to about 1 mm, and the bottom of a 75-micron screen sieved with a vibrating sieve hardly becomes rough even when touched with a finger. That is, as a first step, a glass crusher is to set crushing conditions under which the glass is hardly crushed to several microns.
