When was the space board invented?

Space board was invented and manufactured by Beijing Space Board Industry Co., Ltd. in 2000. Beijing Aerospace Board Industry Co., Ltd. was established with the approval of the Municipal People's Government at the end of 2000, with a registered capital of 365,438+0,845,000 yuan. The company's main product, space board, is a high-tech product, with many invention patents and utility model patents. It is characterized by light weight, high strength, thermal insulation, load-bearing, fire prevention, waterproof, decoration, environmental protection, energy saving, durability, heat insulation, sound insulation, earthquake resistance and many other excellent properties, belonging to environmental protection and energy saving high-tech building plates. The main component of space board is foam cement, commonly known as quick-hardening cement. This structural material has good heat insulation function and light weight. It adopts new technology to organically combine ordinary cement and industrial waste, and realizes the recycling of waste under the concept of environmental protection at the source of production. Houses built with this material are very durable. Space board is a new type of light roof board with artificial light stone as the core material and glass fiber net (or fiber bundle) and steel side ribs as the reinforcing materials. It has the characteristics of good rigidity, high strength and good ductility, and has good structural performance and engineering application prospect. Its own weight is 0.45kN/m 2 ~0.85kN/m 2, and the standard values of all roof loads (including live loads) generally do not exceed 1.5kN/m 2.
