Products Description
1. Firepower
① High-rise buildings have higher fire protection requirements than multi-story buildings. The insulation layer of metal carved hanging panels in high-rise buildings should have fire resistance and should have the characteristics of preventing the spread of fire and the release of smoke or toxic gases in case of fire.
② The material strength and volume cannot be lost too much, and the surface layer should not burst or collapse, otherwise it will cause harm to residents or firefighters and cause huge difficulties to rescue work.
2. Earthquake force
① Earthquake force will cause extrusion, shearing or distortion of the high-rise building structure and insulation surface. The greater the rigidity of the exterior wall metal carved board insulation surface, the greater the earthquake force it will withstand, and the greater the damage it may cause. serious.
② This requires that the external insulation materials of high-rise building exterior walls should meet the principle of flexible gradient on the premise of considerable adhesion to disperse and absorb seismic stress and reduce the load on the surface of the insulation layer as much as possible.
③Prevent large-scale cracking, peeling or even falling off of the insulation layer under the influence of earthquake forces.
3. Water or steam
① In order to avoid damage to high-rise buildings by water or water vapor, external insulation materials with good waterproofing and water vapor penetration should be used for metal carved panels.
② Avoid condensation on the wall or an increase in the moisture content inside the insulation layer during the migration of water or water vapor, which can improve the resistance to rain erosion and freeze-thaw resistance of the external insulation layer of high-rise buildings.
4. Wind pressure
① Generally speaking, positive wind pressure produces thrust, and negative wind pressure produces suction, which will cause great damage to the insulation layer of the high-rise building's exterior insulation and decorative integrated panels. This requires that the exterior insulation layer should have considerable wind pressure resistance.
② In terms of wind pressure resistance, the insulation layer is required to have no cavity air layer, so as to avoid damage to the insulation layer caused by the volume expansion of the air layer in the insulation layer under wind pressure, especially negative wind pressure.
Aging of metal carved panels will affect the use of building materials, and building materials have their own service life. When their lifespan is up, we must replace them to prevent aging from causing trouble in our lives.
