Lightweight partition board is a new lightweight wall material made of cement and fly ash as the main raw materials, and green light inorganic environmental protection and heat insulation raw materials as composite filling aggregate. The weight is only one sixth of the clay brick wall. 

        Lightweight panels have the following characteristics: 1. light weight, high strength, waste, heat preservation, heat insulation, no roasting, fire prevention, easy construction, no steam maintenance, low cost, increase room use area. 2. the extruded strip, the compressive strength is obviously higher than that of other kinds of strip forming methods, and the compactness of strip is an important mark of the quality of strip plate, which is closely related to the strength, water absorption, shrinkage value, sound insulation and hanging force of strip plate. 3. from the construction point of view, the large block construction speed is fast, the construction industrialization degree is high; the factory production (extrusion) surface is flat, reduce the construction site painting wet operation (masonry painting), the thickness of the plate is the thickness of the wall, not only improve the construction efficiency, but also increase the use area and so on. The comprehensive benefit of light wall board is obvious. Therefore, in developed countries, all kinds of light wall panels account for about 50% of the total wall materials, China's current various wall panels only account for about 3% of the wall materials. 

      Because the plate has the specification size neat, easy to form, convenient mechanization production, the production efficiency is high; plus the plate block type is big, the integrity is good, may assemble the installation, can realize the dry work, the construction efficiency is high, enhances the work efficiency more than 5 times than each kind of block and the brick wall body ;" the plate can achieve the production industrialization, the product standardization, the dimension specification modulus, the construction assembly ", easy to control the product quality and the engineering quality; The plate can reduce the total load of building by more than 80%, save the total cost by about 7%, and increase the use area by 5%——8% per 100㎡. Therefore, the development of plate wall is not only a good product advocated by developed countries, but also an inevitable trend of the development of housing industry in China. Therefore, the promotion of wall sheet forming equipment and the production of wall sheet has a strong vitality and broad prospects for development.
