[0002] Polystyrene foam board, EPS board for short, is a common foam plastic board. It is a white foam material with closed cell structure made of polystyrene resin as the main raw material, adding foaming agent and other auxiliary materials, and foaming by heating. Polystyrene foam board has the characteristics of light weight, the density is usually between 10-30kg / m 3 , very convenient to carry and construction, has good thermal insulation performance, low thermal conductivity, can effectively reduce heat transfer, commonly used in building wall, roof insulation engineering, at the same time, its sound insulation performance is also excellent, can reduce noise interference. In addition, polystyrene foam board also has certain buffering performance, can play good shockproof effect, so it is widely used in packaging industry, used for protecting electronic products, glass products and other fragile goods.
[0003] Foaming machine for foam board production is a kind of equipment that can mix foaming agent, water and air and other raw materials fully and produce foam, and then be used for producing foam board, which is usually composed of metering system, stirring system, control system and foaming system, etc. The metering system can accurately control the input quantity of various raw materials to ensure the accuracy of foaming ratio. The stirring system mixes the raw materials uniformly through high-speed stirrer, so that the foaming agent fully contacts with water and air to produce a large amount of fine and uniform foam. The control system can monitor and adjust the parameters such as temperature, pressure and stirring speed of the whole foaming process in real time to ensure the stability of foaming quality. The foaming system makes the mixed raw materials react chemically or change physically under certain pressure and temperature conditions to form foam with certain density and performance. These foams are then transported to the mold and formed through solidification process to finally produce foam board.
