How many levels does the top of the student desk have?

There are three kinds of materials commonly used for the desktop panel of students' desks and chairs, which are multi-layer plywood, moulded board and joinery board. Among them, multi-layer plywood generally has plywood, plywood, nine plywood, etc., and a combination is a layer.

The thickness of a layer is 1mm, and the veneer of each layer is 90° vertical, which increases the strength and reduces the deformation, mainly used on the external surface, such as the curved place, and has good bending. Molded board, also known as the blister board, is usually the choice of high-quality medium density board, milling, sanding, on the surface through the principle of vacuum cover, the PVC film tightly pasted and formed, with good waterproof performance, environmental protection, shape and color texture of various advantages.

Joinery board, commonly known as large core board, is made of two boards in the middle of the glue splicing wood. The middle board is made of high quality natural wood board after heat treatment, processed into a certain specification of wood strips, spliced by the splicing machine.

After splicing, both sides of the board are covered with two layers of high-quality veneer, and then made of cold and hot press. Compared with particleboard and medium density fiberboard, its natural wood characteristics are more compliant with the requirements of human nature. It has the advantages of light weight, easy processing, good nail holding force, no deformation, etc., is the ideal material for interior decoration and high-end furniture production.

In the long run, it is obviously not conducive to the healthy development of students, this behavior is obviously detrimental to the body, the body bones because of the wrong sitting posture and the development trend of deformity, but also the impact on their vision is difficult to erase.
