挤塑板XPS在保温防火性能
作者:admin 来源:本站 发布时间:2016-10-28 17:45:43 浏览次数:372
吸水率与透气性也是一项衡量保温材料保温性能稳定性的重要指标。有机材料尤其是挤塑聚苯板的吸水率很低,具有很好的防水性能。
Water absorption and air permeability is also an important index to measure the thermal insulation performance of insulation materials. Organic materials especially absorbent extruded polystyrene board rate is very low, has a good waterproof performance.

无机类保温材料,如玻璃棉、岩棉、矿棉制品等,具有较大的吸水率和水蒸气渗透率,因而保温效果不够稳定,尤其用于低温保温时 挤塑板XPS首选厂家,此类保温材料一旦含有水分,导热系数会急剧上升,隔热效果将明显降低。

Inorganic insulation materials, such as glass wool, rock wool, mineral wool products, with greater water absorption and water vapor permeability, the heat preservation effect is not stable enough, especially for low temperature insulation extruded plate XPS preferred insulation material manufacturers, such as containing water and thermal conductivity will increase dramatically, the insulation effect will be significantly reduced.
而从防火性能方面考虑,无机材料的优势则甚为明显。对有机材料来讲,防火性能是致命伤。
From the fire performance considerations, inorganic material advantage is very obvious. In terms of organic materials, fire performance is a fatal injury.
从建筑保温材料的使用寿命上看,无机保温材料也有极大优势。在正常使用的情况下,无机保温材料外墙保温系统工程的寿命可与其基层墙体同寿命。然而有机保温材料的使用寿命则相对较短,以聚苯板为例,其使用寿命为15~20年,对于设计寿命为50~70年的普通建筑物来说 挤塑板XPS价格,若使用聚苯板作外墙保温,将意味着同一建筑物一生需作数次外墙保温,这将是一个巨大的工程,所花的费用也是无可估量的。
From the service life of building insulation materials, inorganic thermal insulation materials also have a great advantage. In the case of normal use, the service life of the external wall insulation system of inorganic thermal insulation materials can be the same as the life of the base wall. However, organic insulation material service life is relatively short, with polystyrene board as an example, its service life is 15~20 years, for the design life of ordinary buildings 50~70 years of extruded plate XPS price, if the use of polystyrene board external wall insulation, will mean the same building consisting of external wall insulation life need time, it will be a huge project, the cost of immeasurable.
