The use of environmentally friendly sheet, writing surface color: beige. The surface hardness ≥6 the MO degree. thickness ≥ 0.34 ㎜. water-soluble chalk or clean green pen writing smooth, not slippery. Wipe the handwriting without leaving water droplets, wet write still clear, no dust. The surface is attached with a colorless transparent film, which is only torn before use. can be used as projection, imaging effects: Reference projection screen surface parameters manufacturing, imaging clear, uniform color, not reflective, large visual angle. Mezzanine: The use of high-strength honeycomb paperboard or foam board, thickness ≥14mm, soft and hard moderate, flexible, very good, not deformed, the whole without seams. 4, Back PLATE: The use of rust-proof galvanized steel sheet, thickness ≥0.2mm, zinc content Z12, surface formation, moisture, anti-corrosion, rust-proof, no deformation, the whole without seams.Writing Board With Single
      Plastic Material: ABS factory plastics, mold forming and writing board surface fixed, no right angle, no exposed metal fasteners. Border: The use of high strength Matt Champagne color aluminum alloy, in the sun irradiation does not reflect, built-in track, track integration vertical double curved track design. Mold molding, the outer frame width is less than 91cm for the positive deviation, pulley group integration, the correct sliding mode; Inner border wide ≥30㎜ thick ≥20㎜, wall thickness ≥ 1.0, cast tendons, prevent deformation. The whole board wall is blocked on both sides, and the border color is consistent. Combination mode: The whole environmental Protection Board is assembled from a fixed plate and a movable plate and an outer frame, chute, etc.Writing Board With Single
      The whole board outer frame size 4200mmx1280mm and large-screen LCD TV physical size matching, using a fixed plate and one machine TV parallel installation, a school push-pull writing board supporting a unified lock, easy to use, the movable plate can be completely blocked when closed TV, and can be locked to protect the role of television security; The active writing board can fully reveal the large screen LCD TV when it is open to meet the needs of multimedia teaching in TV.Writing Board With Single
      Enterprises through ISO90 Quality Management system certification and ISO14001 Environmental Management system certification. General writing board thickness of about 0.2mm, the use of High-tech methods to synthesize 5 layers of special materials, 5 quality in combination, so that the writing board has a distinctive characteristics. The reflectivity is 20% higher than the ordinary projection screen, making the image brighter and clearer, obviously improving the projection brightness, eliminating the trouble of turning off the lights and closing the windows. Completely eliminate dust, environmental health, handwriting clearer, writing more fluent. The preset square writing surface, does not need the tool to help, conveniently can face the beautiful table and the graph.Writing Board With Single
