聚苯乙烯泡沫板的参数指标以及作用

Parameter index and function of polystyrene foam board

　　聚苯乙烯泡沫板又名泡沫板、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成型的白色物体，其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，冷库、空调、车辆、船舶的保温隔热，地板采暖，装潢雕刻等用途非常广泛。

Polystyrene foam board, also known as foam board and EPS board, is a white object made of expandable polystyrene beads containing volatile liquid foaming agent, which is heated and formed in the mold after pre heating. It has the structural characteristics of micro closed holes, and is mainly used for building walls, roof insulation, composite board insulation, heat insulation of refrigerators, air conditioners, vehicles, ships, floor heating, decoration and carving.

　　二、聚苯乙烯泡沫板使用效果

2、 Effect of polystyrene foam board

　　1.对建筑物主体结构进行保护，延长建筑物寿命。由于外保温是将保温层置于结构外侧，降低了由于温度变化导致的结构变形产生的压力，并减少空气中有害物质和紫外线对结构的侵蚀。

1. Protect the main structure of the building and extend its lifespan. Due to the external insulation, the insulation layer is placed on the outer side of the structure, reducing the pressure caused by structural deformation due to temperature changes, and reducing the erosion of harmful substances and ultraviolet rays in the air on the structure.

　　2.有效消除“热桥”以往采用内保温，“热桥”是难以避免的，而外墙保温有效地防止热桥的产生，避免结露。

2. Effectively eliminate the use of internal insulation in the past, which is difficult to avoid. On the other hand, external wall insulation effectively prevents the formation of thermal bridges and prevents condensation.

　　3.使墙体潮温情况得到改善，一般内保温需设隔汽层，而采用外保温保温材料的透温性能远远强于主体结构，在墙体内部一般不会发生冷凝现象，结构层的整个墙身温度提高了进一步增强了墙体的保温性能。

3. To improve the moisture and temperature situation of the wall, a vapor barrier layer is generally required for internal insulation, while the thermal conductivity of external insulation materials is much stronger than that of the main structure. Condensation generally does not occur inside the wall, and the overall wall body temperature of the structural layer is increased, further enhancing the insulation performance of the wall.

　　4.有利于室温保持稳定，采用外墙外保温，由于墙体蓄热能力较大的结构层在墙体内侧，有利于室温保持稳定。

4. It is conducive to maintaining stable room temperature by using external wall insulation. Due to the large heat storage capacity of the structural layer on the inner side of the wall, it is conducive to maintaining stable room temperature.

　　5.增加房屋使用面积。可以避免二次装修对保温层的破坏。

5. Increase the usable area of the house. It can avoid damage to the insulation layer caused by secondary decoration.
