According to experts in the field of identification, the Extrusion Polystyrene (XPS) foam sheet production line developed by Germany-Italy is advanced in technology and uses a secondary extrusion foaming process. At the level of digestion and absorption of advanced international technology, the extrusion screw is added to a special mixing section and two static mixers to achieve even mixing of the gas blowing agent and the molten material. With the imported dual-stage high-frequency piston pump, the amount of blowing agent is stable, Precise; special structure hanger die and die lip; foam sheet sizing device and extrusion die lip using hot oil circulation temperature control, at the same time, the production line applies advanced device network control to achieve the level of mechatronics.
China Plastics Processing Industry Association Chairman Liao Yongzheng and Beijing University of Chemical Technology Professor Yan Xiaozheng and seven other experts agreed that the production equipment is the first in the country, and all technical and economic indicators have reached the international advanced level. The XPS foam board produced is a green and environmentally-friendly building material that meets the national building energy-saving industry policy and has good economic, social, and environmental benefits.
Recently, the XPS foamed sheet production line developed and developed by Qingdao Deyili Machinery Co., Ltd. passed the scientific and technological achievements organized by the Qingdao Municipal Bureau of Science and Technology.
