Although the vacuum insulation panel is an insulating material, it is nonflammable and may overload. Therefore, the contact temperature of vacuum insulation board should not be too high. Once the contact temperature of the vacuum insulation board reaches more than 200 ℃, the vacuum insulation board must be protected. At the same time, the installation standard should be strictly followed, and the spacing of insulation nails should be about 400mm.

Teach you how to install and connect Vacuum insulation board : in general, the purpose of installing vacuum insulation board is to achieve the goal of small heat loss. During installation and design, vacuum insulation board and felt should be closely connected; attention should be paid to moisture-proof: Although the vacuum insulation board is used for the external wall of buildings, other materials except basalt are easy to wet, so it is recommended not to construct on the vacuum insulation board in rainy days.

As a new building material, vacuum insulation board has been known to us, and its excellent performance is loved by the construction industry.

The core material filled in the vacuum insulation board is powder core material, glass fiber core material or mixture of powder and glass fiber core material.

 Vacuum insulation board

Micron fumed silica is mainly used as the core material. After air leakage, the expansion of the powder core material vacuum heat insulation board is small, causing damage to the system, while the glass insulation core vacuum insulation board only leaks. The larger the expansion deformation, the greater the damage to the system. Therefore, the core material should be mixed with silica and other special additives, and pure glass fiber core material should be avoided.

Vacuum insulation board is one of vacuum insulation materials. It is composed of a filling core material and a vacuum protective surface layer. The heat transfer caused by air convection is avoided, so the thermal conductivity can be greatly reduced and realized. 002-0.004w/mk, which is 1 / 10 of the thermal conductivity of traditional thermal insulation materials.

1. Vacuum insulation board has good thermal insulation effect, which is 5 times of traditional polystyrene board, 4 times of extruded board and 2.8 times of polyurethane. Buildings in most areas of Shandong usually use 1.5cm thick, which can achieve 65% energy saving requirements. Comparison of thermal conductivity of different thermal insulation materials w / (m · K)

2. The unit weight is relatively light, and the weight per square meter after placing on the wall is about 12kg, which is only 1 / 4 of the weight of the ceramic tile placed on the wall. It is not easy to fall off after construction and has high safety.

3. The organic integration of thermal insulation and decoration engineering is simpler than the construction process of traditional insulation system.

The construction period is shortened and the construction cost is greatly reduced.

5. The thermal insulation material is inorganic thermal insulation material, which has the characteristics of fire prevention and non combustion, and can burn the existing traditional thermal insulation material.
