About the characteristics of the construction plan of rubber and plastic insulation board

In the process of external thermal insulation engineering construction, the external thermal insulation wall of rubber and plastic insulation board is composed of four parts: wall structure layer, insulation layer, protective layer and veneer layer, and one of the external insulation projects is rubber and plastic. Insulation board insulation system. Dealing with the relationship between these four levels is the main technical key to the external wall insulation system.

To deal with the relationship between the components of the outer wall insulation wall of the rubber-plastic insulation pipe, the rubber-plastic insulation board needs to have a clear understanding of the connection between the components and the common problems.

Among them, there are several ways to connect the insulation layer, the protection layer and the structural layer:

Connecting rod bracket; oblique connecting rod bracket; long screw; bonding agent.

The above four connection methods have their own characteristics, but the first three kinds of construction are more troublesome, and the fourth one also involves problems such as bonding strength and durability.

For this purpose, the following four simpler solutions are recommended: nailing scheme; expansion bolt scheme; pre-embedded steel or plastic reinforcement scheme and adhesion and nail combination scheme.

These several solutions are not only convenient to construct, but also have good durability. To prevent and eliminate cracks in the protective layer and the facing layer, and to study measures to reduce the stress concentration and shrinkage stress of the protective layer, it is necessary to deal with the relationship between these three levels. The veneer layer is used as the visual effect of the external thermal insulation technology. The influencing factor of the rubber and plastic insulation pipe is the weather resistance of the protective layer and the veneer layer, which needs to be properly handled during construction.

There are many kinds of feasible methods for this. It is quite effective to spray high-elasticity and weather-resistant exterior wall paint outside the protective layer. Because this coating has good elastoplasticity and waterproof function, Good anti-cracking and weathering resistance, so it has a protective effect on both the protective layer and the thermal insulation layer.

The use of good insulation measures and insulation materials in construction and industry can significantly reduce production energy consumption and cost, improve the environment, and achieve twice the result with half the effort. In the late 1970s, some developed countries in foreign countries began to use rubber and plastic insulation materials in building energy conservation, and achieved great results, and building energy consumption dropped drastically. For example, in Denmark, after using rubber and plastic insulation materials, the heating area increased by 30% in 1985 compared with 1972, but the heating energy consumption was reduced by 3.18 million tons of standard coal. Significant social and economic benefits have led to the rapid development of rubber and plastic insulation materials, and the detection of its performance has also been carried out. This paper briefly introduces the water vapor permeability test of rubber and plastic insulation pipe by Labthink's W3/0120 water vapor transmission rate tester.
