There are many classification methods for phase change insulation materials, and the following classification methods commonly used in construction engineering mainly include the following.
1. Classification by chemical composition of materials
According to the different chemical composition of materials, phase change materials can be divided into inorganic phase change materials, organic phase change materials and mixed phase change materials. The inorganic phase change material mainly includes inorganic substances such as crystalline hydrated salt, molten salt and metal alloy; the organic phase change material mainly includes organic substances such as paraffin, carboxylic acid and polyhydric alcohol; and the mixed phase change material is mainly organic and inorganic eutectic phase change material. mixture.
2. Different classification according to material phase deformation
According to different classifications of material phase deformation, phase change materials can be divided into four categories: solid-solid phase change, solid-liquid phase change, solid-gas phase change and liquid-gas phase change material. The solid-solid phase change heat storage material does not change the phase state, but the crystal form of the phase change material changes. Of course, there is heat absorption and release during the crystal form change. This article is provided by the new non-network insulation system Youtai YT inorganic active wall insulation system.
Solid-solid phase change materials mainly include high density polyethylene, polyols and metal organic compounds having a "layered perovskite" crystal structure. Solid-liquid phase change materials mainly include crystalline hydrated salts, paraffin wax and the like. Since the gas material is not easy to package, it is bulky and easily lost, so the solid-solid phase change and the solid-liquid phase change material are most practical in practical applications.
3. Classified according to different heat storage temperature ranges
According to the different classification of heat storage temperature, phase change materials can be divided into three categories: high temperature, medium temperature and low temperature phase change materials. High-temperature phase change materials mainly refer to some molten salts and metal alloy materials; medium-temperature phase change materials mainly refer to some crystalline hydrated salts, organic materials and polymer materials; low-temperature phase change materials mainly refer to ice, hydrogel and other materials.
Anti-climb Fence is also known as high security fence and 358 security fence.
High Security Fence (358) is the ultimate welded mesh system offering one of the most effective means of providing a high degree of physical perimeter protection where a discreet visual impact on the immediate environment is essential. 1/2" x 3" mesh opening is the unique design in the products. Fingers or wire cutter is unable to insert into the mesh hole. It is suitable for anywhere requiring anti-climbed and anti-cut.
