1, energy-saving building insulation materials and process systems

(1), insulation materials and insulation structure

Building energy-saving insulation system, whether it is within the insulation, or insulation, its thermal insulation efficiency, depending on the thickness of the insulation layer and the insulation properties of the insulation material, which is a key factor in whether a phenolic insulation board interface section squeeze can reach . Insulation material is divided into organic and inorganic insulation materials, insulation materials, organic insulation materials such as expanded polystyrene board (EPS), extruded polystyrene board (XPS), spray polyurethane (SPU), etc., inorganic insulation materials such as hollow glass transition beads, expanded perlite, perlite obturator. Wall insulation layer and the base layer and exterior decoration are the blend, the bottom is the main building outside the walls, the middle layer of insulation, the insulation layer is an anti-crack Which best quality wool board mortar, the external walls cracking putty , exterior paint or decorative tile.

(2), auxiliary materials and construction technology

Auxiliary material is a polymer adhesive mortar, mortar interface treatment agent or interface, special expansion screw, alkali-resistant fiberglass mesh or steel mesh, plastering mortar.

Insulation layer construction technology plate (polystyrene board, extruded sheet) is generally to stick after nails, posted net surface mortar, sticking facing brickwork or putty, paint brush; as insulation layer particle sizing agent (polymer a mixture of mortar and polystyrene particles, hollow glass beads, perlite, perlite obturator, etc.), the construction process is generally the first wipe interface mortar, thermal insulation mortar, paste network, wiping cracking mortar, stickers brick or paint brush.

2, ecological problems thermal insulation system materials

Energy-saving insulation system to achieve energy-saving insulation efficiency, effectiveness, we should spend a lot of money and consume large amounts of raw material resources, and insulation materials mostly single-use, non-renewable energy produced, once it reaches the outer layer of insulation after proper life has been abandoned, it will generate a lot of waste. Currently foam insulation materials polystyrene board, extruded polystyrene board, spray polyurethane, polystyrene particles, auxiliary materials mortar, fiberglass mesh, steel mesh, expansion screws, etc., basically not much reuse value.

Ecological asked phenolic board insulation system Caigang duct processing problems, mainly to insulation, architectural, construction and other main building and the natural ecological environment to adapt, that is, "from nature, return to nature."
