In 2015, the Provincial Department of Housing and Urban-Rural Development released the construction atlas of local standards and EPS module construction applications. Since last year, the company has promoted 600,000 square meters of low-rise buildings and 2 million square meters of high-rise buildings in our province. This technology has been widely used in cold provinces such as Heilongjiang and Inner Mongolia. It has many years of application experience in high-rise and multi-storey buildings, and the current quality is in good condition. The insulation is durable and won’t fall off. During the construction of this project, the EPS modules are assembled first, and then the concrete is poured to form a composite wall to achieve the same service life as the insulation and the structure. The problem of hollow insulation material falling off within 15 years that often occurs in conventional buildings will not occur, so as to achieve the purpose of integration of insulation and structure.
In order to better serve customers and always have an advantage in the market competition, the company has formulated a set of standards. During the whole process, all details are strictly checked to ensure that customers are provided with the best quality products. In the past 20 years, the company has continued to grow and develop, and making every set of equipment excellent has become the focus of our daily work. At the same time, it pays attention to the after-sales service of products, and is known as an honest unit of “keeping reputation and serving first”. In 2009, in the “China Supplier Enterprise Certification System Construction and Implementation” activity held by China Internet News Center, it was rated as “China Credit Enterprise Certification System Demonstration Unit”. In 2014, it was appraised as “Quality, Reputation, Service Consumer Satisfaction and Integrity 3.15 Commitment Unit” by “Consumer Daily”.
Waterborne polyurethane resins have many polar groups, such as polyurethane bonds, urea bonds, and ionic bonds. It has good adhesion to a wide variety of substrates, especially polar and porous substrates. Similar to solvent types, different matrices have different binding strengths. Table 4 shows the bond strength data for a waterborne polyurethane adhesive to various substrates. It can be seen that the water-based polyurethane adhesive has good bonding performance to soft PVC containing more plasticizers.
Because the polyurethane board has excellent thermal insulation properties. It can reduce the thickness of the building’s protective structure and increase the indoor usable area. Not easy to crack. 5. Strong resistance to deformation. Stable and secure end. It’s basically a closed cellular structure. 6. The porosity and structure of the polyurethane insulation board are stable. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. Under normal use and maintenance conditions, the average lifespan of rigid polyurethane insulation structures can reach more than 30 years. Guarantee that the structure will not be damaged by dry, wet or galvanic corrosion, as well as external factors such as insect, fungal or algal growth or rodent damage under normal use conditions during its service life. This increase will be offset by substantially lower heating and cooling costs. Number 7. Comprehensive cost-effective. Although rigid polyurethane foam costs more than other aggressive insulation materials.
Material coefficient Thin plastering exterior wall insulation module is mainly composed of polymer mortar with flexible bonding function of bonding layer, insulation layer, protective layer with crack resistance and waterproof function, protection and reinforcement accessories, alkali-resistant glass fiber mesh, anchors, brackets, etc. Composition, corner protection and other polymer insulation mortar is the key technical material of the system. In this paper, the polymer insulation mortar is analyzed in detail.
