Steel desks and chairs will also have poor quality products, some manufacturers are not good production process, there will be desktop spray plastic began to fall off, the steel part of the rust. Desks and chairs from the shape, from a single form gradually transitioned to lifting type, even type and other more ergonomic multiple forms. Moreover, with the development of youth height and weight changes. At home and abroad there are desks and chairs standard re-revision of the problem, but there are different, mainly reflected in the placement of desks and chairs, relative to the domestic generally neat and tidy, foreign students desks and chairs are placed in a flexible and diverse. Student desks and chairs by a worker or a group of workers in the case of no change of equipment or location to complete the assembly work, called the assembly process.One with the same tools and aids, do not change the method of work, and in a fixed continuous Yazhou completed assembly work, called the work step. In an assembly process can be included in a rarer or child assembly work step. Total assembly and component assembly are composed of a number of assembly processes. As far as the composition of the product is concerned, the component is the smallest unit that constitutes the product. A number of parts are combined to form a component that becomes a part of the product .Regardless of the form and method of combination, are collectively referred to as parts.Total assembly and component assembly are composed of a number of assembly processes.

The correct production process should be: when the steel is returned, the surface should be treated in order to prevent rusting.

Then before spraying, we should first acid wash to remove the oil, and then use professional degreasing formula to remove the oil on the steel surface. Sometimes steel is left too long to completely prevent surface rust, and then remove the rust from the steel. After the oil and rust are removed, the surface of the steel will become very smooth. After this step is completed, the steel needs to be phosphatized immediately in order to prevent the steel in the rust removal solution from being oxidized by the air.Sometimes steel is left too long to completely prevent surface rust, and then remove the rust from the steel.

After this step is completed, the steel needs to be phosphatized immediately in order to prevent the steel in the rust removal solution from being oxidized by the air.
There is a thin phosphate film attached to the surface of the steel after the phosphating solution treatment, which can well prevent the steel from oxidizing in the air. A series of treatment process is completed. Then before spraying the plastic powder, make sure that the steel surface is dry and free of dust, so that the sprayed plastic powder will be tightly adhered to the steel surface. It will not fall off easily even with a hammer. After rigorous treatment, the tables and chairs produced can generally be used
for more than 5 years, and the plastic powder will not fall off or rust. Therefore, it is recommended that schools must scrutinize the manufacturer’s processing technology before purchasing desks and chairs. Be sure to see if the quality meets the standard. So that we can use it easily.
