Description
Technical field
The utility model relates to a kind of glass, especially a kind of blackboard screen glass.
Background technology
The frosted glass of the band frosting that existing blackboard glass generally is black, the chalk that is used for classroom or other environment is write, to write the clear more frosting that generally requires comparatively coarse in order to allow, but so, Dust Capacity when writing is bigger, and comparatively difficult when wiping, need firmly wiping could know written contents fully.And existing blackboard glass be used to only limit to chalk and write, the blank that also needs configuration ink pens in addition to write in places such as multi-media classrooms, the equipment such as curtain of projecting apparatus projection.
The utility model content
It is little that the purpose of this utility model provides a kind of dust, and wiping makes things convenient for union black and white plate, projection screen blackboard screen glass.
To achieve these goals, but the following technical scheme of tempering two-way mirror of the present utility model:
It comprises glass body, and its improvement is: glass body at least the one side on be provided with the PVB intermediate coat, be provided with magnetic material layer on PVB intermediate coat surface.
Preferably, described glass body thickness is 3 millimeters.
Preferably, described magnetic material layer thickness is 2 millimeters.
Owing to adopted such scheme, blackboard screen glass of the present utility model replaces the blackboard of conventional usefulness.Have reliable in quality, durable in use, fluent writing, writing is clear, easy-to-write and erasable, Dust Capacity obviously reduces, and is moistureproof, anti-skidding, never distortion, never the advantage of situation about not falling is wiped in appearance; Also can serve as projection screen uses, though be bulletin, or the teaching, have more the bonus point effect, it can make projection light source condense more, allow you when watching film, no longer light source deficiency, color are lost Jiao, the cloth curtain is not easy smooth problem as having on traditional cloth curtain, also can save the expense of buying projection screen.Can be used for the business office meeting, the oil pen smears need only be with the light wiping of general cleaning agent, can the scratch corrosion surface, and permanent as new.
