New Type Building Materials XRY Extruded Plate Creates Perfect External Wall Insulation â–¡ Beijing Dingsheng Xinyuan Environmental Protection Decorative Technology Development Co., Ltd. Extruded Polystyrene (XPS) Insulation Board, with polystyrene resin as the main raw material, continuous extrusion foaming through special process Formed hard sheet, with anti-high pressure, moisture, airtight, non-absorbent, corrosion resistance, long life and other advantages. Extruded polystyrene insulation boards are widely used in wall insulation, cryogenic storage facilities, building concrete roofs, and structural roofs. The extruded board has a closed-cell performance structure and its closed-porosity rate reaches 99%, so the insulation performance is good. Although the foamed polyurethane has a closed-cell structure, its closed-cell ratio is smaller than that of the extruded plate, and it is only about 80%.
Extruded panels are superior to other insulation materials in terms of their thermal insulation properties, water absorption properties, and compressive strength. Therefore, they are also incomparable to other insulation materials in terms of thermal insulation properties.
The extruded board also has unexpected compressive strength. The compressive strength of the extruded board can reach 150-500 kPa or more according to its different model thickness, while the compressive strength of other materials is only 150-300 kPa or more. It can be clearly seen that the compressive strength of other materials is far lower than the compressive strength of the extruded board. The extruded board can effectively waterproof and infiltrate, especially in the north, it can reduce the occurrence of frost and frozen frost and other conditions, and can effectively block the air from moisture damage.
Moreover, the construction of the extruded board is convenient, low in cost, light in weight, easy to handle, easy to cut, easy to fix, and can be reused.
However, the extruded polystyrene board has the advantages of good closed-cell structure, low water absorption, and low thermal conductivity. Therefore, there has been a trend of increased application in the recent period, but the cracking phenomenon is more common in the completed external thermal insulation projects. The degree of cracking is also more serious. In addition to the reasons similar to the expansion of polystyrene board thin plaster external wall insulation system, there are the following reasons: 1, although extruded polystyrene board has good insulation and waterproof, but because of its high strength, high deformation stress, smooth surface , hydrophobic, difficult to bond and other reasons, mainly used in foreign countries and the ground below ± 0 wall insulation. At present, when domestically used for wall insulation without system research, if it does not strictly control the material properties and is verified by a large-scale weatherability test, a serious quality accident will inevitably occur.
2. The benzene board has higher density and higher strength than the expanded polystyrene board, and the deformation stress due to its own deformation and temperature difference deformation is also large. Compared to each board seam, the stress change of the two adjacent boards is reversed. , Squeezing or pulling at the seams of the board causes cracking at the board seams.
3. The benzene plate has a smaller thermal conductivity of 0.029 W (mK), and the thermal conductivity of the cracking mortar is 0.93 W/(mK), while the thermal conductivity of the two layers differs by 32 times, compared to the polystyrene plate and the resistance. Cracking mortars have a greater difference in thermal conductivity and therefore are more prone to cracks. Therefore, due to the lack of large-scale weatherability test and successful engineering demonstration of the wall, the application of benzene board in wall insulation is restricted.
In this regard, XRY energy-saving decorative panels to break the conventional thinking put forward the concept of insulation decoration design of the product, the benzene board as insulation core material, directly in the factory and the external decorative surface layer made of energy-saving decorative panels. It can be said that the application of benzene board has realized the advantages and disadvantages, and it has realized the benzene board as an excellent side of the physical properties of the wall insulation material, and solved the problems that restrict its development.
Based on a thorough investigation of the domestic and international thermal insulation market, Beijing Dingsheng Xinyuan Company has repeatedly studied for five years and developed a new type of energy-saving decorative material for the integration of thermal insulation and decoration of exterior walls of buildings. This product completely breaks through the existing process limitations, overcomes the limitations of thinking, and adopts an innovative way of thinking to combine the insulation layer with the decorative layer to carry out the modular production of the plant. The site is directly dry-hanged and wet-stick (hanging paste) in the gap. The use of embedded thermal insulation strips, hooking with flexible sealing pastes or weatherproofing sealants fundamentally solves the problems of cracks, rising drums, and falling off. Its unique module molding process and on-site sticking and mounting technology are fully applicable to each There are new and old building facades that are energy-saving, insulating and decorative. Because the benzene board and the decorative layer were combined in advance, the problem of easy cracking of the benzene board was avoided at all. And its stone series of energy-saving decorative panels in the stone decorative surface layer is generally thinner than the traditional stone decorative panels in the process of nearly 3/4, in which the thickness of ultra-thin granite slate is 6 mm, 18 kg per square meter, reasonable in the benzene board On the basis of utilization, the effect of saving 300% of the material is achieved. Only one-fourth of the weight of the traditional curtain wall is used, especially the decorative brick only has 18-20 kg, which is 40-60 per square meter than the traditional insulation tile. Kg reduced the weight by 50%, coupled with advanced hanging paste technology, can be applied to the development of benzene board to an unlimited extent, especially for high-rise building insulation and decoration can be described as more secure energy.
Because the insulation layer is made of extruded polystyrene foam for insulation as the core material, the thermal conductivity is guaranteed at 0.028w/m2, and the energy saving can reach 75%. Due to the reduction of the impact of the stone's own weight, the selection of surface materials in high-rise buildings There is also more room for the selection of materials from light materials such as aluminum panels, aluminum-plastic panels, and fluorinated carbon metallic paints, to a variety of stone, fiber-ceramic, and brick-decorative panels. Because the energy-saving decorative board mechanically synthesizes the heat preservation and decoration at the factory, the site only needs to be manually operated by sticking or hanging or by sticking and affixing, which reduces the labor cost and difficulty of on-site construction, and greatly shortens the construction period. At present, this energy-saving decorative panel and its curtain wall system have been applied in projects such as the China Construction Academy’s building of an integrated office building, the Beijing Xin’aofang Housing Community, the Hubei Provincial People’s Congress Office Building, the Beijing Huachen Building and the Beijing Xinyueyue Industrial Park. 0 Construction Technology
