Environmental-friendly Fluorine-free CO2 Foaming XPS Extruded Insulation Board Series Production Line (standard Model)

The XPS extruded polystyrene foam board production line is a type of insulation board formed by high-temperature extrusion using polystyrene and foaming agents as raw materials. Currently, in the industry, chlorofluorocarbons (HCFC) are mainly used as foaming agents. HCFC foaming agents have a relatively high potential to damage the ozone layer. According to the Montreal Protocol, China has been gradually restricting the use of HCFC. Based on market conditions, our company has introduced advanced technology and specially developed CO2 extruded polystyrene board equipment for customers. CO2 has completely replaced fluorine, chlorine and hydrogen foaming agents, truly achieving a fluorine-free foaming process and setting a precedent for CO2 foaming.

Multi-component blending system

The fully automatic computer controls the proportion of various raw materials, adopts the precise measurement method of weightlessness, and strictly mixes the raw materials according to the set, laying a foundation for the production of high-end quality products. The feeding system adopts vacuum feeding to ensure the stable transportation of raw materials.

Cooling, constant temperature system

The precise proportional control cooling system is equipped with a high-power chiller to ensure excellent cooling performance and meet the strict requirements for the cooling system in the production process.

Extrusion system

The CO2 XPS extrusion system adopts a parallel twin-screw extruder with a modular screw structure, which is combined and used according to the processing technology of the materials. The specially designed connection method and transmission device enhance the strength of the threaded elements and mandrel, achieving uniform dispersion of materials and good mixing.

Supercritical CO2 blowing agent injection system

The supercritical CO2 foaming agent injection system is a utility model patent product developed by our company. It adopts a fully imported flow control system to precisely control the instantaneous volume flow and mass flow of the foaming fluid. A closed-loop control program is designed to maintain the stability of the mass flow. The unique three-stage pressurized injection system maintains a stable liquid-phase state of CO2, ensuring the formation of a homogeneous system. It also adopts an automatic flow feedback control system to maintain the stability of the foaming agent flow.

Conveying system

The forming system is equipped with a bidirectional electrically adjustable device, a proportional control low-resistance system material, and double-sided shaping

Fixed-length cutting

Online post-processing system, for products that have been cooled and formed, automatic fixed-length cutting, edge trimming, longitudinal and transverse edge forming, automatic stacking, multi-point monitoring, automatic alarm, and automatic packaging system.
