Features of XPS heat-preservation board production line
XPS foamed polystyrene board (referred to as XPS) has a perfect closing-cell honeycomb structure, and is recognized as one of the best insulation materials in market. EPS is materialized by recycled polystyrene board and reproduction foam particle which are processed by extrusion, foaming and shape forming from die heads. haul-off, cutting to accomplish product manufacture process. It is lower than other kinds of heath preservation board materials in density, water-absorption rate, heat conductivity factor, steam permeability factor and so on. Therefore, it has features of good strength and light weight; it is air proof, corrosion resistant, anti-aging, low pricing and etc. The material is widely applied in roof insulation system; refrigerating store room, barracks, granary, and civil architecture wall insulation; airport runway, squares and other ground construction fields; road, railway civil engineering; the insulation separation system in departments, office buildings, factories and other constructions.
The equipments for XPS have two kinds, one of which is tandem single-screw extruder, and the other one is one-way parallel tandem single-screw extruder. Standards: SJ135/ SJ150 single screw extruder in tandem and SJ75/ SJ150 single screw extruder in single-direction parallel tandem. They can process various materials together. Our newly developed vacuum sizing machine adopts methods of vacuum molding under negative pressure, which promises the quality of product panels as well as reducing product weight in order to reduce production cost.
