Carved board thermal insulation exterior wall decorative board is a new type of exterior wall thermal insulation decoration material in the field of external wall thermal insulation in recent years. It has good fireproof, waterproof, and corrosion resistance, and is one of the most ideal materials among various exterior wall materials on the market. It can reach 0~100℃ for normal use. At the same time, it has strong anti-aging ability and excellent anti-ultraviolet performance, which can meet the fading and cracking of various ultraviolet radiation and high-intensity use as well as long-term open-air storage conditions.
I believe that everyone can encounter carved panels for thermal insulation and exterior wall decoration panels in daily life. In winter, the indoor heat loss of the house is very fast. If the insulation performance of the wall is not good, more heat sources are needed; in summer, the outdoor temperature is too high. If the walls are not well insulated, an air conditioner will be needed to cool the room. These two reasons directly lead to the high energy consumption of houses. In order to better develop the construction industry, carved panels for thermal insulation and exterior wall decoration panels came into being.
The emergence of carved panels for thermal insulation and exterior wall decoration plays an important role in energy saving and environmental protection of buildings. With the continuous development of the times, its application scope has become more extensive, and it has made important contributions to promoting social development.
However, when we develop products, we often talk about the functions and requirements of the carved board thermal insulation and exterior wall decorative panels, but we often forget the requirements for the wall during construction. The success or failure of the construction of the carved board thermal insulation exterior wall decorative board is inseparable from the wall conditions. What specific criteria need to be met?
First of all, the base layer of the wall should be dry and firm. The surface of the voucher should be clean, and there should be no attachments that hinder bonding, such as oil stains. Surface flatness is not greater than 4mm. Protrusion. Empty drums and loose parts should be removed, and leveled with 1:3 cement mortar; the flatness should be ±2mm. For the base layer with too dry surface or high water absorption rate, the paste test should be carried out first; paste the insulation board in the external insulation system, remove the insulation board after 5 minutes, and paste it back to its original position. If it can still be kneaded by hand, it is qualified, and it is responsible for indicating that the base layer is too dry or the water absorption is too high (that is, the viscosity of the test mortar)
1. Good insulation performance
Compared with traditional thermal insulation materials, thermal insulation decorative panels can reduce about 1/3 of heat loss at lower temperatures, which is equivalent to the thermal insulation effect of traditional thermal insulation materials with the same thermal insulation effect. In addition, the external wall thermal insulation decorative board does not burn has a thermal insulation effect, can meet the fire protection standard, and has excellent thermal insulation performance.
