聚苯乙烯泡沫板
Polystyrene foam board
聚苯乙烯泡沫板是常见的三种内墙保温材料之一。又名泡沫板、EPS板，是由含有挥发性液体发泡剂的可发性聚苯乙烯珠粒经加热预发后，在模具中加热而成型的白色物体。
Polystyrene foam board is one of the three common internal wall insulation materials. Also known as foam board and EPS board, it is a white object formed by heating and heating the mould by preheating the expandable polystyrene beads containing volatile liquid foaming agent.
其据有微细闭孔的结构特点，主要用于建筑墙体、屋面保温、复合板保温等。分为膨胀性EPS板(苯板)和连续性挤出型XPS板(挤塑板)。
According to the structural characteristics of micro closed holes, it is mainly used for building wall, roof insulation, composite board insulation, etc. It is divided into expanded EPS board (benzene board) and continuous extrusion XPS board (Extrusion board).
1、优点
1, advantages
(1)密度系数小，抗冲击能力良好，有足够的能力通过改变和回复形状对外界冲击力进行缓冲。
(1) the density coefficient is small, the impact resistance is good, and there is enough ability to buffer the external impact force by changing and restoring the shape.
(2)具有独立的气泡结构，小面积的损伤不会影响到整面墙体。
(2) with independent bubble structure, small area damage will not affect the whole wall.
(3)其表面吸水率低，防渗透性能好，能够有效避免墙面受潮后发霉、脱落等墙面问题。
(3) it has low surface water absorption and good impermeability, which can effectively avoid wall problems such as mildew and falling off after the wall is affected by moisture.
(4)不受气温影响。高温时，聚苯乙烯泡沫板不会因温度过高而熔化流淌，低温时也不会因为温度过低而发生脆裂现象。
(4) not affected by temperature. At high temperature, polystyrene foam will not melt because of the high temperature. It will not break down due to the low temperature.
(5)聚苯乙烯泡沫是可回收材料，能够回收使用，其回收程度是塑料中最高的。
(5) polystyrene foam is a recyclable material that can be recycled, and its recovery is the highest in plastics.
(6)生产工艺中不使用氟利昂;。
(6) Freon is not used in the production process;.
(7)全生命周期的能耗在塑料制品中最低的。
(7) the energy consumption of the whole life cycle is the lowest among plastic products.
