岩棉夹芯板
- 产品介绍
岩棉夹心板
在单重，导热，抗压强度，水分方面，岩棉夹芯板不比聚苯乙烯和聚氨酯夹芯板好
吸收率和其他物理和机械性能。 但是可以在600℃的使用温度下使用。 此外，该型面板具有A级不燃性的突出特点，因此岩棉夹芯板的使用范围扩大到轻质建材高
对防火等级的要求。
岩棉夹心板：
钢板厚度：0.3mm〜0.7mm;
夹层厚度：50mm〜250mm
可用宽度：950mm，1150mm
可用长度：通过定制

Characteristics:
1) The fireproof performance is excellent: the materials and the technology of the panel have good fireproof performance, it can withstand the fire above 1000℃ The rock wool sandwich panel has passed the test that carry out by the country professional organization, the fireproof grade is A,incomplete combustion.
2) The performance in heat reserve and heat insulate is good, the heat reserve and heat insulate performance of rock wool sandwich panel depends on the thermal conductivity λ=0.043W/m2K, it is calculated according to the proportion thickness of rock wool core material.
3) The effect in sound insulate is excellent, rock wool sandwich panel will make any effect in preventing the transfer of the noise, especially suitable for the specific area where the scheduled flight pass. And if adopt the rock wool sandwich panel, the sound that make by the rain, hail will be decreased. Through the test , according to the ISO 717/82 and the UNI 8270/7 standard , choose the rock wool core material whose density is 100kg/m3, the effect in sound insulate can achieve RW=29~30 dB.
