Analysis of advantages and disadvantages of insulation materials
1, Vacuum insulation board organic insulation materials. such as foaming Polystyrene Board (EPS), Extruded Polystyrene Board (XPS), spray polyurethane (SPU), and polystyrene particles. Organic insulation material has light weight, machinable good, high density, good insulation effect, but the disadvantage is: non-aging, deformation coefficient, stability, poor safety, easy to burn, eco-environmental protection is very poor, construction difficult, project cost is high, its resources are limited, and difficult to recycle.
2, inorganic insulation material. such as hollow glass beads, swelling perlite, closed Kong Zhenzhu rocks, rock wool, etc. Inorganic insulation material weight slightly larger, heat insulation insulation thermal efficiency is slightly worse, but fire retardant, the deformation coefficient is small, anti-aging, stable performance, with the walls and the surface layer of good combination, safety and stability, insulation layer strength and durability than organic insulation materials high, long service life, construction difficult, low engineering costs, eco-friendly, can be recycled.
3, Vacuum insulation composite materials. In case of radiation endothermic materials, rock wool, or even treated crops straw, can be used with insulation and harmless treatment of garbage, and through foaming technology, such as the production of hollow materials. The insulation effect of composites is good, it has many advantages of inorganic insulation material: fire retardant, the deformation coefficient is small, anti-aging, stable performance, good eco-environmental protection, high insulation layer strength, long service life, small construction difficulty, low engineering cost, the source of raw materials, energy consumption, eco-friendly, can save resources, improve the recycling efficiency of resources.
