These planks honeycomb structure, will not appear void, this closed-cell insulation material structure can have different pressures (150-500Kpa) also has the same low thermal conductivity (only 0.028W / MK) and durable not bad excellent thermal insulation and compressive properties, compressive strength of up 220-500Kpa. XPS plate surface flatness depends on the production of raw materials and production equipment Laiwu extruded sheet, using native materials xps board Binzhou extruded sheet, surface smoothness is much higher than the existing use of the secondary recycled materials xps board, in Used to ensure flatness of the wall, in use Boshan extruded sheet, wrong seam bonding has been promoted as a new technology, the use of alkali-resistant mesh cloth xps plate surface, with a special anchors fixed after use specially treated surface mortar, flatness of the wall is much stronger than in the past to use the EPS system.
