1、硬质聚氨酯板导热系数低,热工性能好。当硬质聚氨酯容重为35~40kg/m3时,导热系数仅为0.018g~0.023w/(m.k),约相当于EPS的一半,是所有保温材料中导热系数最低的一种。 1. Hard polyurethane board has low thermal conductivity and good thermal performance. When the bulk density of rigid polyurethane is 35-40kg/m3, the thermal conductivity of rigid polyurethane is only 0.018g-0.023w/(m.k), about half of that of EPS, which is the lowest thermal conductivity of all thermal insulation materials. 2、硬质聚氨酯板具有防潮、防水性能。硬质聚氨酯的闭孔率在90%以上,属于憎水性材料,不会因吸潮增大导热系数,墙面也不会渗水。 2. Rigid polyurethane board has moisture-proof and waterproof properties. Rigid polyurethane has a closed porosity of more than 90% and belongs to hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep. 3、硬质聚氨酯防火,阻燃,耐高温。聚氨酯在添加阻燃剂后,是一种难燃的自熄性材料,其软化点可达到250摄氏度以上,仅在较高温度时才会出现分解:另外,聚氨酯在燃烧时会在其泡沫表面形成灰,这层灰有助隔离下面的泡沫。能有效地防止火灾蔓延。而且,聚氨酯在高温下也不产生有害气体。 3. Rigid polyurethane fireproof, flame retardant, high temperature resistance. Polyurethane is a flammable self extinguishing material after adding flame retardant. Its softening point can reach above 250 degrees Celsius. It will decompose only at higher temperature. In addition, polyurethane will form ash on the surface of foam when it burns. This layer of ash helps to isolate the foam below. It can effectively prevent fire spreading. Moreover, polyurethane does not produce harmful gases at high temperatures. 4、由于聚氨酯板材具有优良的隔热性能,在达到同样保温要求下,可使减少建筑物外围护结构厚度,从而增加室内使用面积。 4. Because polyurethane sheet has excellent thermal insulation performance, under the same thermal insulation requirements, it can reduce the thickness of building envelope structure, thereby increasing the indoor use area. 5、抗变形能力强,不易开裂,饰面稳定、安全。 5. Strong anti-deformation ability, not easy to crack, stable and safe decoration. 6、聚氨酯材料孔隙率结构稳定,基本上是闭孔结构,不仅保温性能优良,而且抗冻融、吸声性也好。硬泡聚氨酯保温构造的平均寿命,在正常使用与维修的条件下,能达到30年以上。能够做到在结构的寿命期正常使用条件下,在干燥、潮湿或电化腐蚀,以及由于昆虫、真菌或藻类生长或者由于啮齿动物的破坏等外因影响,都不会受到破坏。 6. Polyurethane material has stable pore structure and is basically closed-cell structure. It not only has good thermal insulation, but also has good freeze-thaw resistance and sound absorption. The average life of rigidzhuguangzhi.37ix.com.cnjinyinzhi.37ix.com.cnsekazhi.37ix.com.cn tongfengg.37ix.com.cnshusongdaih.07858.netshusongdaif.07858.net foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. Under the normal service life of the structure, the structure will not be destroyed under the conditions of dry, wet or electrochemical corrosion, as well as because of the growth of insects, fungi or algae or rodents. 7、综合性价比高。虽然硬质聚氨酯泡沫材的单价比其它传统保温材料的单价高,但增加的费用将会由供暖和制冷费用的大幅度减少而抵消。 7. High comprehensive price ratio. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by a substantial reduction in heating and refrigeration costs. |
