XPS extrusion board is extruded polystyrene insulation board, is the polystyrene resin as raw material, other raw materials and polymer inclusions, heating and mixing, and then injected into the catalyst, and then extruded into the rigid foam board.　　A, the advantages of XPS extruded plastic board 1. thermal insulation, energy saving and environmental protection.　　2. Compression and impact resistance, superior strength.　　3. Impermeable and waterproof, stable performance.　　4. Durable, good quality.　　5. Convenient construction, low cost.　　Second, the application of XPS extruded plastic board 1. in the construction of cold storage, extruded plastic board is essential. It not only plays the role of heat insulation, but also due to the microporous structure of the surface of the extruded plastic board, can absorb and buffer a small amount of water vapor condensation, reducing the formation of water droplets. The extruded panels for cold storage are highly demanding, with a thickness of 10cm or more. So in cold storage construction, usually use two layers of extruded plastic panels, one is to increase the thickness, the second is staggered splicing two layers of extruded plastic panels to increase insulation and avoid temperature loss.　　2. XPS squeeze plastic board used as a foundation mat, the airport highway paving foundation, etc.. Extruded plastic board waterproof moisture, the use of 50 years without deterioration or infiltration, effectively alleviate the road leakage caused by the collapse of the foundation.　　3. Home decoration is the ground pavement, now more used is extruded

Insulation materials are divided into three categories: porous materials, heat-reflective materials and vacuum materials. The former uses the pores contained in the material itself to insulate, because the air or inert gas within the pores has a low thermal conductivity, such as foam, fibre materials, etc.; heat reflective materials have a high reflection coefficient, can reflect the heat out, such as gold, silver, nickel, aluminium foil or metal-plated polyester, polyimide film, etc. Vacuum insulation materials are used to block convection by using the internal vacuum of the material to insulate. The aerospace industry has harsh requirements for the weight and volume of insulation materials used, and often requires it to have both sound insulation, vibration damping and corrosion protection properties. Various aircraft

The main factors affecting the thermal conductivity of insulation materials

The main factors affecting the thermal conductivity of insulation materials

I. Types of materials Different types of insulation materials (thermal insulation materials) have different thermal conductivity. The physical thermal properties of insulation materials differ according to their material composition, and their thermal conductivity or coefficient of thermal conductivity differs according to their insulation mechanism. Even for insulation materials made of the same substance, the difference in thermal conductivity can sometimes be significant due to differences in internal structure or in the control process of production. For solid insulation materials with low porosity, the thermal conductivity is greatest for crystalline structures, followed by microcrystalline structures and least for vitreous structures. However, for insulation materials with high porosity, the influence of the gas (air) on the thermal conductivity plays a major role.

The water absorption rate of water-repellent insulation materials is an important factor that should be considered when choosing insulation materials. The thermal conductivity of water at room temperature is 23.1 times that of air. The thermal conductivity of water at room temperature is 23.1 times higher than that of air. The water absorption of insulation materials will not only greatly reduce its thermal insulation performance, but will also accelerate the corrosion of metals, which is therefore very harmful. Insulation material void structure is divided into connected type, closed type, semi-closed type several, in addition to a few organic foam void most of the closed type, other insulation materials regardless of how the void, its material itself water absorption, plus the capillary penetration of connected void water absorption, so the overall water absorption rate are higher. At present most of the insulation materials are not abhorrent
