2) Use the slotted groove angle will board cut notches, Nanjing xps extrusion board, the recess 15 is not less than the thinnest point. 3) should be designed convex line angle cut to size, the angle and the corresponding line on both sides of the insulation board a brush interface agent, and then painted with special adhesive, xps extrusion board, making it a solid paste. Wipe the bottom polymer mortar 1) polymer mortar configuration with special binder. 2) configured polymer mortar spread evenly on the plate thickness of 2 mm. Advantages XPS system is that: 1), XPS board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the same thickness of EPS, EPS and therefore has relatively better thermal insulation properties. For the same building facades, its thickness can be less than other types of insulation materials. 2), since the closed cell structure of the inner layer. So it has good moisture resistance, in a wet environment, Jining xps extrusion board, still maintain a good thermal insulation properties; suitable for cold storage and other special requirements for insulation building materials can also be used for external walls as brick or stone buildings. 3), XPS board has a good compressive strength, in construction, easy to crack and damage, which attributed to the high compressive strength of XPS boards.
