Third, the first main factor exterior insulation material selection: the low thermal conductivity? EIFS because the threshold is not high technology, standards and policy guidance in the composition of the material is often the system and the system itself is isolated and there is hysteresis eps insulation board manufacturers, the domestic part of the designer for exterior insulation technique is not well understanding and mastering vacuum insulation board manufacturers, some of the practices still exist for external insulation vague concept, often think the choice of external insulation, low thermal conductivity main material, is a good exterior insulation system, lead to the design and construction of touch, plus part of Enterprises misguided, but also a wide variety of exterior insulation technology, good and bad. From the perspective of building mechanical and thermal engineering in building exterior insulation and external decoration system, it should be regarded as a composite whole structure to study, and should not be separated into structural layer, insulating layer, crack layer, and Research finish layer separately. Thermal studies show that after installing insulation insulation board manufacturers, due to good thermal insulation properties, resulting in the insulation layer, the outer side showing a different thermal environment, therefore, composite structures of Guangzhou insulation board manufacturer, should be based insulation The dividing line to engage in various studies. Based on this understanding, we choose the external wall insulation system for basic analysis. One. XPS and XPS bonding: ※ commonly used in pipe insulation works, duct, or laminated with thick XPS extruded plate, such bonding can MPU-20 one-component special adhesive. The principle of this adhesive is cured by moisture curing reaction, the source of water for the water to be sticky surface adsorbed moisture in the air and artificial spray water. Conventional curing time of 5-6 hours. If you want a fast curing methods can be taken at: according to 100: 3 ratio, (that is, three grams of water was added 100 g gel), if the glue is added with 1000 g of water 30 g. After adding water, stirring constantly, to make adhesives and water thoroughly mixed, then glue from the original dark brown liquid into a pale yellow foam. After the glue foam, evenly applied to the surface of the material (single can), some time after drying the adhesive can. Temporarily available tape or rope, wire and other bundled improve adhesive strength. Achieved significant adhesion strength after one hour. After 24 hours to achieve optimum strength. Note: The amount of glue have good control, depending on the material, how much how much down, to avoid wastage; if not sure, you can pour a little experiment first. To glue reservoir cap tightened to prevent moisture ingress to make the glue to cure.
