Status desks and chairs - desks and chairs on the development of production
Student desks and chairs in China with the West in general follow the development path of the school desks and chairs. From the composition of materials and development of history, the two are not significantly different, have experienced hardwood manufacturing (first generation) - Steel-wood-in-One (second generation) - Hard plastic replacement stage; From the outside, from a single the form of a gradual transition to a lift, even the type, and so many more in line with ergonomic shape. Moreover, with the young height and weight development and changes. The standard desks and chairs at home and abroad there further amendments of the problem, but there are also different, mainly reflected in the placing of desks and chairs questions general uniform in relation to domestic and foreign students in the placing of desks and chairs are flexible.
Developed through three stages
From the very start of China's educational undertakings have the size of the school, counting more than 100 years of history, student desks and chairs has continued manufacture of traditional hardwood. After the reforms of the early 80s, a few large cities Wood Products Factory to learn from foreign experience, from the manufacture of furniture using steel and wood in-one start, and then use the same method of production of the second generation of students in the school with desks and chairs to replace some of the wood products . Steel-wood desks and chairs even after 20 years of development, have adopted the mechanical method of production, but will loose nails, easy to rust and short service life and many other ills, we can not completely replace the first supply tables and chairs. In most parts of central and western rural schools, students are still mostly in the manufacture of the first substitute the use of hardwood tables and chairs. The many years of use have also proved that manufacture steel and wood quality of student desks and chairs have been no better than the first generation of educators recognized a good number of wooden desks and chairs, so development time Despite the continuing 20 years, the pace of development was very slow , is also still only as a transitional product, instead of part of wood products. Advances in technology, high-rise buildings in developed countries of the raw materials used in doors and windows have been through "Wood - Iron - Aluminum Alloy," in three stages, beginning 10 years ago, all entered the period of hard plastic instead of aluminum. In recent years, science and technology to design a large number of steel parts instead of cars, trains, ships, aircraft wood, iron, aluminum and other parts, the performance is far superior to the former. With plastic on behalf of the wood, plastic and steel, plastic and brass on behalf of the aluminum is an inevitable trend of scientific and technological progress, but also the future development of China's manufacturing industry the only way for desks and chairs are no exception. Moreover, the future can not only adjust height of desks and chairs, as well as kinds of even-type desks and chairs, from the height-adjustable desks, chairs and adjustable from the lessons of the connecting plate of the composition, it has resolved the existing primary and secondary school desks can not adjust the high chair table, chairs high, tables and chairs away from the problem, suitable for all ages and grades, students use a variety of shape can focus on the individual situation of each student desks and chairs adjust itself to full compliance with state health standards.
