How to choose the external wall insulation decorative panels become a troubled moment a lot of customers, external wall insulation decorative board many manufacturers, product mixed. Now external wall insulation decorative plate professional manufacturers - Chengdu dispatch color energy-saving Materials Co., to tell you about how to select high-quality exterior insulation decorative board an insulation performance external wall insulation decorative one board to buy facades? insulation decorative board concern, of course, its insulation properties. What are its thermal performance insulation material used in the decision. In general, organic insulation materials (eg EPS, XPS, polyurethane, phenolic foam, etc.) than the inorganic insulating material (such as rock wool, glass wool, perlite, foamed cement, etc.) insulation is better. Second, an indicator of external wall insulation decorative plates fire rating at attention while insulation properties, fire rating is that we should focus on, the external wall insulation decorative board as a whole, building decoration materials, large-scale construction, not fireproof insulation materials easily spread fire. Therefore, we must choose the high level of external walls of fire insulation decorative panels. Similarly, the external wall insulation decorative plates fire rating is determined by the flammable insulation materials, insulation materials, fire rating is divided into A, class B. A superior fire performance grade insulation material. A grade insulation materials: rock wool board, foam ceramic plates, cement foam board, glass foam board, polyurethane composite panels, composite insulation board, STP, perlite board, inorganic glass beads of insulation mortar. Class B insulation material: EPS wall insulation board, XPS external wall insulation composite panels, rigid polyurethane foam composite insulation board, phenolic fireproof panels. Comprehensive insulation and fire resistance, the current polyurethane wall insulation composite panels, insulation properties and fire performance phenolic wall insulation composite panels preferred, but also by the most widely used. 1, stable performance composite panels have organic polymer insulation materials, chemical stability, insulation decorative stone panels, corrosion resistance strong, will not change in the acid rain, CO2 effect. Modified polyurethane aging intensity of temperature range, external wall insulation decorative stone panels, use a temperature of -50--150 ℃, not brittle at low temperatures, does not flow at high temperatures, normal use, short-term use temperature up to 250 ℃ without any damage, is the most widely used temperature insulation material that can be applied to all areas, including cold and hot regions, and will not mildew, foster parasites. Organic polymer insulation materials at plus or minus 70 ℃ temperature change, the rate of dimensional change in air humidity of 45-75% environment <1%, stone texture board supply, the reason for the gas bubbles in the CFCs within this environment, volume does not change, the network backbone (cell wall) is a thin foam base isocyanate curing composition, negligible distortion. 2, bonding and sealing properties of the organic polymer insulation material with fluidity and permeability, in itself is a good binder containing polar group in the structure of the adhesion of various materials -NCO- pole , and can enter into the surface layer of the adhesive foam voids, and grass-roots firmly bonded and sealed voids act, its bond strength than the tear strength of XPS foam itself, so that the foam layer and sticky Results level to become one, easy to delaminate. According to the table display: XPS Ge EPS foam directly on a base without any treatment agent, as long as the base surface moisture content <10%, can be effectively bonded, seamless no cavity integral seal. Synthetic insulation decorative integration board is an organic liquid in the mold formed by the high-pressure foam, insulation and decorative layer is 100% free of cavities mechanical connection, its adhesive quality can be directly detected by the apparent ensure finishes hollowing layer will not cause the stone to fall off.
