巖棉夾心板
在單重，導(dǎo)熱，抗壓強(qiáng)度，水分方面，巖棉夾芯板不比聚苯乙烯和聚氨酯夾芯板好
吸收率和其他物理和機(jī)械性能。 但是可以在600℃的使用溫度下使用。 此外，該型面板具有A級(jí)不燃性的突出特點(diǎn)，因此巖棉夾芯板的使用范圍擴(kuò)大到輕質(zhì)建材高
對(duì)防火等級(jí)的要求。
巖棉夾心板：
鋼板厚度：0.3mm〜0.7mm;
夾層厚度：50mm〜250mm
可用寬度：950mm，1150mm
可用長(zhǎng)度：通過(guò)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.
