What is the special booster pump for plastic foaming carbon dioxide

xps insulation board? XPS air conditioning insulation board is extruded polystyrene insulation board, which takes polystyrene resin as raw material and other raw materials and polymers in LED lighting system. It is a hard foamed plastic board made by heating, mixing and injecting into the downstream rolling mill to digest a part of the inventory catalyst, and then extruding and pressing it into shape. Its scientific name is extruded polymer for insulation

what is XPS insulation board? XPS air conditioning insulation board is extruded polystyrene insulation board. It is a hard foamed plastic board made of polystyrene resin as raw material, other raw and auxiliary materials and polymers, which is heated, mixed, injected with catalyst, and then extruded and molded. Its scientific name is extruded polystyrene foam for thermal insulation (XPS for short). XPS has a perfect closed cell honeycomb structure, This structure makes XPS board have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance and aging resistance (there is almost no aging decomposition phenomenon in normal use). This kind of XPS insulation board is often used for building roof insulation, steel structure roof, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air conditioning ventilation ducts, etc

and an essential process for the production of XPS insulation board is "foaming"! How to make foaming? It is generally divided into physical foaming 178 malleable iron castings and chemical foaming, and today we want to talk about "physical foaming"! Physical foaming requires a kind of special pneumatic gas physical foaming equipment of Nexant, that is, the liquid CO2 booster pump to be mentioned in this paper

Its technical indicators and performance reach the level of modern foreign similar products

the maximum flow of XPS insulation board foaming equipment (liquid carbon dioxide pressurization system) provided by our company can reach 400nl/min, the maximum working pressure can reach 500bar, and the pressure adjustment error is ± 2bar

with its excellent gas pressurization and control technology, Dongguan Nexant provides high-pressure gas physical foaming equipment necessary for XPS insulation board foaming production line with stable performance. Gas assisted injection molding technology uses high-pressure inert gas to inject into the molten plastic to form a vacuum section and drive the molten material forward to realize the process of injection, pressure maintaining, cooling and so on. The advantages of this kind of gas physical foaming lie in forming thick products, very smooth inner surface and short cooling time
