First, the exterior insulation cracking mechanism: flexible deformation of the gradient layer by layer, layer by layer to release stress? In theory, the EIFS each structural layer extruded sheet is cut to separate interior and its parts placed on the same test environment, the establishment of a unified flexible deformation of the measure, it should be said, "gradient layer by layer, layer by layer to release stress," the crack mechanism is plausible. However, in terms of the current exterior insulation system of general application, this premise is untenable. First, each structural exterior insulation layer as a building complex systems, there is a whole level inside and outside, can not cut and split, it is impossible to accept all kinds of stress or the nature of external shocks in the same environment; followed by As the composition of the material system, which set the deformation index is inconsistent, as the elastic modulus of the insulation layer, the surface mortar crimping ratio, flexible putty flexible deformation amount. Since it is inconsistent, it lacks the same comparison basis. Thus, at present, some textbooks widely preached a cracking mechanism extruded sheet, in fact, a conceptual model of careful scrutiny it is untenable. New building materials performance and function vary, the production of new building materials and products, raw materials and process methods also vary. Warm extruded sheet, focusing on some varieties of colors, endless varieties in terms of its development, such as decoration materials; some varieties focusing functions, such as insulation materials; some are derived through the deep processing of multiple varieties, such as The new building boards and the like. Case in New Architecture Board. New Architecture Board currently has dozens of varieties, including gypsum board, glass fiber reinforced cement (GRC) panels, asbestos-free calcium silicate board is currently China's largest production volume, the most common of the three New Architecture Board. These three plate not only the raw materials used different facades extruded sheet, the production process is different, its performance and functions are different. Such as the main raw material for gypsum board gypsum and glossy paper, suitable for use as interior wall panels and ceiling panels; glass fiber reinforced cement board is the main raw material for low-alkali cement and alkali-resistant glass fibers, suitable for use as wall panels; Si-Ca The main raw material is silicon calcium board, and as well as internal and external wall, but also for decoration as well as making and housing together furniture. The three panels of the same characteristics are: the use of them as the original plate, and then were accompanied by seepage, thermal insulation, fire and other functional materials, composite technology, can produce all kinds of light and excellent performance of new wall materials. In addition, they are the raw materials used are non-metallic materials, and also the three most non-metallic materials readily available in the market development is also very good, caused repercussions in the market it is great.
