Rock wool, EIA inorganic insulation mortar, polystyrene particles, polystyrene foam board advantages and disadvantages comparison?
Rock wool (mineral wool): it is a kind of inorganic green product from natural mineral, non-toxic and harmless. The utility model has the advantages of good fireproof performance and good durability, and can be synchronized with the structure life, and the price is low. When the insulation performance is satisfied, the utility model can also have a sound insulation effect, and the fire prevention grade is level a. But the quality of rock wool is very different, and the heat preservation performance is good, the density is low, the tensile strength is low, and the durability is poor, and the paint can not be used directly.
Polystyrene foam board: polystyrene foam board is polystyrene resin as the main raw material, foaming agent made by foaming, with numerous closed microporous material. The utility model has the advantages of small density, small thermal conductivity, low water absorption, good sound insulation performance, high mechanical strength, high dimensional accuracy and uniform structure. But its flammability, combustion, release of toxic gases styrene, B3 grade materials. In the 3.15 exposure of fire accidents, polystyrene foam board accounted for a large proportion, the country has banned the use of.
Polyphenyl granule thermal insulation slurry: polyphenyl granule heat preservation slurry is composed of polyphenyl granule and heat preservation rubber powder material. This kind of thermal insulation material water absorption rate is higher than other materials, use must do crack waterproof layer, fire rating is B2 grade, crack resistant waterproof protective layer material by crack cement mortar composite glass fiber network.
EIA: it is a kind of inorganic thermal insulation mortar. It has many similarities with the performance of rock wool. It has good fireproof performance and good durability. It can be synchronized with the structure life. But its handle is better than rock wool, fire class A1, light capacity, low thermal conductivity, high tensile strength, good bonding effect. Can improve the working conditions of workers, harmless to construction personnel, easy construction, directly to the wall, without any binders, direct coating.
