GPES板的微孔结构具有什么作用

来源:http://www.sdyingxu.com/news/86.html 发布时间:2017-06-19

GPES高性能保温板与普通挤塑聚苯板相比,虽然共聚基体本质上差别不大,但由于成型工艺不同以及混炼接枝技术的引入,在微观结构上却存在着显著的差异, GPES 板具有更加均匀的微孔结构,促使其热工性能和物理性能均显著优于传统有机保温材料。

GPES high performance insulation board and extruded polystyrene board, although there is little difference between the copolymer matrix nature, but due to the introduction of different process and mixing grafting technology, microstructure but there are significant differences, the GPES board has a more uniform pore structure, make its thermal and physical properties are significantly better than the traditional organic insulation materials.

高性能保温板GPES抗拉强度、导热系数、尺寸稳定性、弯曲变形、弯曲强度等指标均优于传统的保温材料。

The tensile strength, thermal conductivity, dimensional stability, bending deformation and flexural strength of the high performance insulation board GPES are better than those of traditional thermal insulation material.

GPES是由改性纳米石墨、多种高分子聚合物以及高阻隔性材料、阻燃剂等经高温高压混炼而成,采用通过调节聚合物混炼熔体延性、韧性与勃度,提高了聚合物熔体温度场均匀度和高分子聚合物混炼接枝率。

GPES is composed of modified nano graphite, polymer polymer and high barrier materials and flame retardant with high temperature and high pressure is made by mixing the polymer mixing, by adjusting the melt ductility, toughness and viscosity, improve the polymer melt temperature field uniformity and polymer mixing rate of graft.

通过调节泡沫板自由释放阻力,以维持挤出口高压状态(7~12MPa )。经高温高压混炼、低温调性、高压挤出,获得了泡孔更均匀、直径更小、高闭孔率、圆度好、壁更薄的微孔结构。从而获得导热系数更低、物理性能更佳的新型高性能保温材料。

By adjusting the free release resistance of the foam board to maintain the high pressure state of the extrusion port (7 ~ 12MPa). Through high temperature and high pressure mixing, low temperature tonality and high pressure extrusion, the microporous structure with more uniform bubble, smaller diameter, high closed cell ratio, good roundness and thinner wall was obtained. Therefore, a new type of high performance thermal insulation material with lower thermal conductivity and better physical properties is obtained.

GPES板具有导热系数更低,初始导热系数小于0.021W/ (m·K),耐老化导热系数在0. 026W/ ( m·K),密度32~38k。有较高的压缩强度、抗拉强度、水率小、尺寸稳定性好等特点,燃烧性能为B₁级,同时价格为聚氨酯保温板的二分之一,优于目前市场其他保温材料。

GPES board has lower thermal conductivity, the initial thermal conductivity is less than 0.021W/ (M = K), aging resistance, thermal conductivity of 0. 026W/ (M = K), density 32 ~ 38k. A higher compression strength, tensile strength, rate of water is small, good dimensional stability, combustion performance of B level, at the same time the price for the 1/2 polyurethane insulation board, insulation materials other than the current market.

结合不同的保温构造形式,完全能够满足75%节能标准和超低能耗被动式绿色建筑技术标准要求。

Combined with different insulation structure forms, it can fully meet the requirements of 75% energy-saving standards and ultra-low energy consumption passive green building technical standards.
