How to Choose the Insulation Core Material of Insulation Decorative Board?

As a key component of new housing construction, the integrated board of thermal insulation and decoration design is warmly welcomed by the sales market because it integrates decoration design, thermal insulation, energy saving and consumption reduction, and with lower cost, it can achieve the actual effect of building curtain wall decoration design. How much do you know about the thermal insulation materials you choose?

In addition to decorative art, the fire resistance, heat insulation, moisture resistance and fire resistance of the core board of the wall insulation decoration design system should be considered in its quality. Next, we will introduce the selection of wall insulation materials for you closely around the insulation core board (EPS, graphite polystyrene board, polyurethane material, rock wool board, etc.) used by Tianyang.

1. Fire resistance rating in recent years, the emergence of several building insulation fire accidents has aroused the thinking of the community on the fire prevention of thermal insulation materials. The fire stability performance of thermal insulation materials has aroused the attention of all sectors of the industry. Fire resistance rating of poor quality thermal insulation materials (rock wool board): non combustible data. Fire resistance grade B1 (graphite polystyrene board): flame retardant insulation material. Fire resistance grade B2 (EPS, polyurethane): Combustible thermal insulation materials, also known as flame retardant materials, are mostly organic thermal insulation materials, with appropriate amount of flame retardant added. Fire resistant grade B3: flammable thermal insulation materials, which are mostly polystyrene foam based materials for thermal insulation materials.

2. Thermal insulation thermal insulation performance is one of the key properties of the integrated panel. The thermal insulation of buildings is the key aspect of energy saving, living environment and application function. On the basis of actively participating in China's "energy saving and consumption reduction" policy, Tianyang series thermal insulation decoration design integrated panel actively develops new thermal insulation materials and conforms to structural thermal insulation and energy saving, and emphasizes the purposeful application of thermal insulation materials, design and engineering construction according to the standard specifications, so as to comprehensively improve the thermal insulation efficiency and reduce the cost. Graphite polystyrene board is a classic thermal insulation material, polyurethane foamed polyethylene, which is further refined by chemical method. Its heat transfer coefficient is less than 0.032. Its thermal insulation capacity is more than 30% higher than that of ordinary EPS, which is conducive to improving energy consumption and reducing carbon dioxide emissions. EPS insulation board continues the advantages of traditional foam board with small heat transfer coefficient and large heat storage coefficient, and has good heat insulation effect. Polyurethane insulation board has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell rate of its structure reaches more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring the stability and stability of its thermal insulation performance. Rock wool insulation board is made of basalt and other iron ore as the key raw materials, which is melted into chemical fiber at high temperature, then solidified with appropriate amount of adhesive. It is a new type of fireproof board with strong fire resistance.

3. Dampproof in the aspect of dampproof, as the heat transfer coefficient of the thermal insulation material will increase after absorbing water, the material with low water absorption or no water absorption should be selected for the thermal insulation core board to avoid the increase of heat transfer coefficient due to the water absorption of the thermal insulation material. As the molecular structure of polyethylene does not absorb water, the molecular structure of EPS insulation board is stable and has no gap, which solves the problems of water leakage, water seepage, frosting and condensation of other materials. After melting at 1450 ℃, rock wool insulation board is centrifuged into chemical fiber by advanced four axis centrifuge
