Panel furniture has been welcomed by many families because of its streamlined shape, varied style, and high quality and low price. However, many friends worry about the quality of panel furniture . The following is a small series of good landscape homes to summarize the six major considerations for the purchase of panel furniture.
1. The difference between the plate furniture is the paper veneer or the wood veneer. The easiest way is to observe the pattern. The wood veneer has natural thrift, color difference and texture change, and then it is touched by hand, and the hand feel is different.
2, the edge of the panel furniture is very important. Pay attention to the advantages and disadvantages of the edge-sealing material, and pay attention to whether the edge-sealing is uneven or lifted. It is important to note that it is not sealed on all sides - although a formaldehyde-free adhesive is used, the wood-based panels are more or less volatile during the manufacturing process, and the edges are tightly sealed. Of course, the environmental protection of the living room is good.3, but also look at the firmness of the furniture structure. First, the gap between the door and the drawer of the furniture. If the gap is large, it means that the work is rough, and the time will be deformed. Second, it is a single box or a double box. Usually, in addition to the outer layer, the furniture is also inside. There should be a layer of panels. This is called a double box. The furniture in the double box is both beautiful and strong.
4, the quality of the paint. Are there any streaks in the pigment? Are the pigments in the corners too thick? Are there cracks or bubbles? These are all carefully examined. I have to ask the salesperson for a few paints on the furniture. Of course, the more times you have, the better.
5. From the hinge groove and the eye-opening area, it can be seen that the plate furniture material is medium density or particle board. One of the best methods is to carefully observe the hinge groove and the eye-opening area, and expose the internal structure. It can be seen that it is used. Particleboard is also a medium density board.
6, the use of hardware, can be disassembled and assembled is the biggest advantage of panel furniture, so the quality of the connector is closely related to the quality of the entire furniture. Imported furniture is expensive on these fine details.
Good scenery home said: It is a common method to judge the quality of a piece of furniture from the aspects of furniture, texture, hardware, and firmness. The multi-purpose furniture of the panel furniture is composite material, so there is a certain gap in the service life compared with the solid wood furniture, so it is necessary to pay more attention to the maintenance.

Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
