介绍山东保温挤塑板的特性及其吸水率:
Introduces the characteristics of shandong extruded insulation board and bibulous rate:
具有高热阻、低线性、膨胀比低的特点,其结构的闭孔率达到了99%以上,形成真空层,避免空气流动散热,确保其保温性能的持久和稳定,相对于发泡聚氨酯80%的闭孔率,领先优势不言而喻。
Has high heat resistance, low linear, low expansion ratio, the characteristics of the structure of the obturator rate reached more than 99%, the ion of a vacuum layer, avoid air flow cooling, to ensure that the insulation performance of lasting and stable, relative to the foam polyurethane obturator rate 80%, lead is self-evident.
实践证明20mm厚的XPS挤塑保温板,其保温效果相当于50mm厚发泡聚苯乙烯,120mm厚水泥珍珠岩。因此本材料是目前建筑保温的最佳之选。
Practice shows that XPS extruded thermal insulation boards of 20 mm thick, its heat preservation effect of 50 mm thick foam polystyrene, 120 mm thick cement perlite. So this is the best choice of building insulation materials.
吸水率是衡量保温材料的一个重要参数。保温材料吸水后保温性能随之下降,在低温情况下,吸入的水极易结冰,破坏了保温材料的结构,从而使板材的抗压及保温性能下降。
Bibulous rate is an important measure of thermal insulation material. Heat preservation material after absorbing heat preservation performance drops, under the condition of low temperature, the water freezes easily inhaled, destroyed the structure of the thermal insulation material, so that the plate of compressive strength and thermal insulation performance.
由于聚苯乙烯分子结构本身不吸水,板材分子结构稳定,无间隙,解决了其它材料漏水、渗透、结霜、冷凝等问题。

Due to the molecular structure of polystyrene itself is not bibulous, plank molecular structure is stable, no clearance, solved the other material leakage, seepage, frosted, condensation, and other issues.
