Student desks and bunk beds are common student furniture. They are more exposed to students, so many factors must be considered when choosing them.
Iron bed in student furniture: the main pole of the bed is made of 40 × 40 × 1.5mm square tube, the bed frame is made of 25 × 50 × 1.5mm square tube, and the bed frame is 4 × 20 × 40 × 1.2mm Welding of thick square tubes; bed frame is welded from 25 × 25 × 1.2mm thick square tubes; L-shaped gear adopts 19 × 1.2mm diameter tube, the total height of the bed frame is 185.0mm, and the bottom plate is 430mm from the ground. The climbing ladder is made of 20 × 40 × 1.2mm thick square tube, the climbing ladder is made of 2mm thick 20 × 40 × 1.2mm square tube, the guardrail is composed of 20 × 20 × 1.2mm thick square tube, the bed frame and the main pole and TH connection. The E screw, fence and bed frame are welded, and the ladder and bed frame are threaded. The steel parts are protected by carbon dioxide gas welding, and the ripple on the welding surface is uniform. No slag, blowholes, welding knobs, wire bite, spatter, etc., to ensure no welding, welding, welding, etc. After the steel parts have been pickled, phosphated and dried, the bottom feet are made of black wear-resistant PA plastic (nylon) feet, and all steel pipes are covered with black wear-resistant PA plastic (nylon).
At present, the melamine desks on student desks are mostly based on MDF and particleboard. In contrast, the performance of MDF is better than the latter. The internal structure of the medium density fiberboard is uniform, the bonding force is greater than the particleboard, the deformation is small, the surface flatness is good, and the nail holding force is strong. Therefore, the melamine board is made of MDF substrate, which is more durable and can play the role of a plate-shaped table top, which is not conducive to assembly. The quality of particleboard is relatively loose and the clamping force is poor, which is lower than the former. Paper with colored or woodblock prints is fragile, and it is difficult to form a film impregnated with melamine board transparent resin. The paper has good performance after hot pressing of the substrate. Tables made with it do not have to be painted, and the surface naturally forms a protective film, which is wear-resistant, scratch-resistant, and acid- and alkali-resistant. High temperature and pollution resistance.
Under the limitation of its own conditions, the human angle can reach the limit; the area between 45 degrees and 60 degrees is the main range of human reading and writing, the operation of the keyboard, etc .; 35 degrees is the maximum viewing angle that can be achieved. D consists of rotating eyes alone; between 0 and 35 degrees is used a monitor. Best time zone. According to relevant data, the ideal distance for adults is 305-460mm, the minimum reading distance is 406mm, and the ideal distance for fixed display is 457-610mm.
