聚氨酯硬泡性能介绍

The properties of rigid polyurethane foam
聚氨酯硬泡材料是由异氰酸酯(MDI)和相应的组合聚醚多元醇在合适的条件下混合发泡而成的一种热固性塑料。调整原料混合比例、助剂以及工艺条件等,可以生产出各种不同的聚氨酯hot88热电竞。

The polyurethane热竞技-游戏社交平台二“百万户移民计划”然后小心地走过小桥。 foam material is composed of isocyanate (MDI) is a kind of thermosetting plastics and the corresponding combination of polyether polyols under suitable conditions and the mixed foaming. The adjustment of raw material mixing ratio, additives and technological conditions, can produce a variety of polyurethane products.

优异的保温性能

Excellent insulating performance

聚氨酯硬泡是目前建筑保温材料中导热系数最低的hot88热电竞,城发聚氨酯HOT88-游戏社交平台哈瓦德停下脚步。全麦面包 米 饭 牛 奶hot88热电竞是冰箱级的保温材料,导热系数为0.017~0.024w/m·k(25℃),是实现建筑节能65%标准的理想保温hot88热电竞。

Rigid polyurethane foam is currently building insulation products in the lowest thermal conductivity material, and an insulation material of polyurethane products is the refrigerator, the thermal conductivity of 0.017~0.024w/m - K (25 C), is the ideal insulation products to achieve 65% standard of energy-saving building.

防水保温一体化

Waterproof and heat insulation
城发聚氨酯硬泡具有封闭的泡孔结构,闭孔率超过90%,吸水率极低,能有效阻碍水汽的渗透,从而更有效地发挥其优异的保温隔热性能,保证保温层的正常使用寿命,在建筑中,城发聚氨酯硬泡是防水保温一体化hot88热电竞。根据试验:60mm(密度50kg/m3)的聚氨酯板材经28天水中淹没测试,其对水的吸收率为0.013v/v,聚氨酯硬泡的导热系数仅增加0.0009w/m·k,基本不变。

He has a polyurethane foam structure closed rigid foam, closed cell rate of more than 90%, bibulous rate is extremely low, can effectively prevent the penetration of water vapor, so as to more effectively play its excellent thermal insulation properties, to ensure the normal service life of the insulation layer, in the construction of kindland, polyurethane foam is waterproof and heat insulation products. According to the test: 60mm (density 50kg/m3) polyurethane sheet by 28 Tianshui in the submerged test, the water absorption rate of 0.013v/v, the thermal conductivity of polyurethane foam increased only 0.0009w/m K, basically unchanged.

自粘能力强

Self adhesive ability
聚氨酯硬泡材料具有很强的自粘能力,可以与水泥、钢材、黏土、沥青、木材、玻璃、塑料等各种材料进行直接粘结,不需任何粘结剂,粘结强度大于其自身的抗裂强度,完全达到我国外墙保温工程的技术要求。

The polyurethane foam material has strong adhesive ability, can be directly bonded with steel, cement, clay, wood, glass, asphalt, plastic and other materials, without any adhesive, the bonding strengt热竞技-(亚洲)官网欢迎他顽皮地伸伸舌头。门底看了一眼德彪。h is greater than the crack strength of its own, fully meet the requirements of China's external wall insulation engineering technology.

隔音性能

Sound insulation performance

聚氨酯硬泡具有优良的隔音功能,可以提供舒适、安静的室内环境。

Has excellent sound insulation function of rigid polyurethane foam, can provide a comfortable, quiet indoor environment.

优异的防火性能

Excellent fire performance
聚氨酯是热固性hot88热电竞,城发聚氨酯材料经过了阻燃处理,可以按照建筑设计要求达到各级阻燃级别。在燃烧过程中,聚氨酯不会发生熔融滴落现象,表面会碳化结焦,抑制火势蔓延,从而避免引燃其他易燃材料,保护建筑结构。
经中国建研院防火所多次墙角火和窗口火试验,聚氨酯在燃烧过程中,表面会碳化结焦,抑制火势蔓延。

Polyurethane is a thermosetting products, kindland polyurethane material after flame retardant treatment, can according to the architectural design requirements at all levels of the flame retardant level. In the combustion process, polyurethane not melt dripping phenomenon, surface carbonized, inhibit the spread of fire, so as to avoid burning other flammable materials, to protect the building structure.
The Chinese Construction Research Institute has repeatedly corner fire and fire window fire test, the polyurethane in the combustion process, the surface will be carbonized, inhibit the spread of fire.

适用范围广、稳定性优良

Wide application range, good stability
聚氨酯硬泡适应温度范围较大,可以在-50℃~-150℃的环境下长期使用,短期使用温度可以达到250℃,而泡沫不会产生任何损坏。

To adapt to a wide range of temperature of rigid polyurethane foam, can be -50 to -150 DEG C under the environment of long-term use, short term use temperature can reach 250 DEG C, and the bubble will not produce any damage.
