Children's learning table is divided into two points: safety and accuracy.
Firstly,safety can be subdivided into four sections: plate, surface flatness, table leg load-bearing and inclined machinery, which are described in detail below.
1. Plate: material and surface coloring
. At present, most materials in the market can be divided into three categories: granular board, solid wood multi-layer and pure solid wood. Because of their different manufacturing processes, the price and safety are from high to low. Particle board is not recommended for individuals. The glue content is too high and the formaldehyde content exceeds the standard, which has a great impact on children's physical development. How to distinguish these three kinds of plates? You can baidu. I won't elaborate here. Surface coloring can be divided into paint, melamine paper and PVC. The paint contains benzene, which is not recommended personally.
2.
Surface flatness: This is easy to distinguish. You can tell by touching it. If there are no pits or burrs, the process is better. Teach you a little skill. Try to touch the side of the table against the wall. If that side is well done, it is basically of high quality. Why there is a difference between good and bad flatness is related to the process during production. In addition to plates, the table also includes plastic parts and metal parts. When making plastic parts, some factories are injection molded and some are not. In the production of metal parts, some surfaces are treated, such as aluminum alloy wire drawing, and some cannot be done. Therefore, the flatness will vary greatly. In terms of cost, more than 2 million injection molding machines are better than 100000, so the final products will be very different.
3.
Table leg load-bearing: in fact, the core of the table is load-bearing. Laymen only look at whether the table legs are thick or not. In fact, this is one-sided. It depends on the thickness and material. Table legs are generally made of plastic, iron and steel, and steel is preferred. Plastic load-bearing is poor, iron is easy to rust and corrode for a long time.
4. Tilting machine: many desktops on the market can be tilted. Most of them fall into two categories: gear adjustment and stepless adjustment. Gear adjustment is one gear at a time, mostly three gears. Stepless regulation is to stop at any time. Gear adjustment is a fixed angle, not flexible without pole adjustment., Stepless regulation is recommended. Stepless adjustment still depends on the hydraulic rod, that is, the damper. Depending on the material, aluminum alloy is preferred.
Secondly,Accuracy can be subdivided into desktop height adjustment and table tilt angle adjustment.
1. The desktop height is 55-78cm, because 55cm is suitable for children with a height of about 1m, and 78cm is suitable for normal adults, that is, 3-18 years old.
2. For the table oblique angle, select 0-55 ° for gear adjustment and 0-25 ° for stepless adjustment.
3. Desktop size: it depends on the size of the family's children's room. The desktop of a smaller room can be 90cm * 70cm, and that of a larger room can be 120cm * 70cm
