Ten, energy-saving and environmental protection performance in Table 1 are several insulation materials insulation materials comparison table names thermal conductivity (w / mk) the relative thickness of the insulation layer than RFT-controlled Phase Change saving insulation material 0.03 1.0 0.042 1.4 extruded polystyrene board insulation board Insulation Adhesive Polystyrene insulation 0.038 1.27 0.060 2.0 RFT-controlled phase change storage energy performance of energy-saving insulation materials is consistent with the three-step energy requirements, with a Class A fire performance, do not produce poisonous gases in case of fire, the fire performance is much better than extruded polystyrene board and board. Meanwhile RFT phase change material from thermostat thermostat phase change mechanism, can reduce energy waste, saving up to 65%, with considerable social and economic benefits, and therefore should be widely applied. Table 2 Several environmental performance of insulation materials comparison table: RFT-controlled phase change energy saving insulation materials powder polystyrene particles polystyrene board (EPS) material properties break the traditional single thermal performance of insulation materials, thermal capacitance and resistance the compressive strength of two single thermal insulation performance of a single thermal resistance compressive material reaches 114Kpa, it can be directly received light on the material surface, after the received light to form a hard film layer, its intensity can adapt putty thermal stress, reduce the cracking mortar layer. After forming loose material, polystyrene particles bond is not strong, can not directly receive light, it must be added to concrete and mortar layer surface-treated plate itself is low compressive strength, can only rely on the surface layer of cement mortar to maintain its surface strength, resistance the impact of the poor. Easily damaged and difficult to repair. Special construction crack resistance brucite fibers form a mesh tension structure to ensure the integrity of the material; and by the material and the wall surface of the alkaline hydroxide ion substitution reaction of the free acid form of non-physical height bonding, ensure the wall effective bond, combined with the material itself is a 5% volume expansion, fundamentally overcome the crack, crack. The ratio of the material is on site mixing, since the ratio of human action, there will be differences, this will between the different constituent material cracks. Sheet metal seams inevitably produce varying degrees by the thermal expansion and contraction cracks in the cracks prone to thermal bridges. Weathering phase-change materials are all from natural minerals, the physical treatment, of a small molecule, inert, stable performance to ensure stable performance of the material as a whole. Polystyrene insulation material surface protection is difficult if not long-term stable use. Once the surface is damaged, the powder particles due to the infiltration of water, so that the powder "wet back soft" adhesion loss of a large area off. Poor frost resistance, easy to aging, wind pressure. A class flame retardant Noncombustible. In the current fire rating is the highest level of wall insulation materials B1 B1 level environmental protection material does not contain radioactive elements radon and other harmful ingredients and phenol, crushing the powder particles are green products from recycled polystyrene board insulation materials on the market, recovery uncertain origin, hygiene uneven.
