挤塑板的闭孔结构有什么作用?

一、优越的抗水、防潮性
First, excellent water resistance, moisture resistance
挤塑板具有紧密的闭孔结构,聚苯乙烯分子结构本身不吸水,板材的正反面都没有缝隙,因此吸水率极低,防潮和防渗透性能极佳。
Extruded plate have a closed cell structure closely, polystyrene molecular structure itself does not absorb water, positive and negative plates are no gap, so water absorption rate is extremely low, moisture-proof and anti permeability performance is excellent.
二、防腐蚀、经久耐用性
Two, corrosion resistance, durability

一般的硬质发泡保温材料使用几年后易老化,随之导致吸水造成性能下降。而挤塑板因具有优异的防腐蚀、防老化性、保温性、在高水蒸气压力下,仍能保持其优异的性能,使用寿命可达30-40年。

The general use of hard foam insulation materials after a few years of aging, resulting in water absorption resulting in decreased performance. But because of the extrusion plate corrosion and excellent ageing resistance, thermal insulation, water vapor in high pressure, can still keep its excellent performance, service life can reach 30-40 years.

三、具有优异、持久的隔热保温性
Three, with excellent, lasting thermal insulation
(1)尽可能更低的导热系数是所有保温材料追求的目标。挤塑板主要以聚苯乙烯为原料制成。
(1) as far as possible lower thermal conductivity is the goal of all insulation materials. Extruded plate with polystyrene as main raw materials.
(2)而聚苯乙烯原本就是极佳的低导热原料,再辅以挤塑押出,紧密的蜂窝结构就更为有效地阻止了热传导,聚能板导热系数为0.028/m。
(2) and polystyrene was originally an excellent low thermal conductivity material, supplemented by extrusion extrusion, the honeycomb structure is more closely to prevent heat conduction, thermal conductivity of 0.028/m shaped plate.
