Rock wool sandwich panel Rock wool color steel sandwich panel Fireproof color steel plate Steel plate thickness 0.476

The rock wool sandwich panels produced by Zhongchao Purification give full play to the unique properties of rock wool core materials and have significant effects in fire prevention, thermal insulation, sound absorption and sound insulation. . Excellent fire resistance: The raw materials, production process and formula used in rock wool sandwich panels make it have very good fire resistance. Tests have shown that it has superior fire resistance. The rock wool sandwich panel has passed the test of the Italian authoritative testing agency. In accordance with the standards of the International Organization for Standardization, British B and Germany, the rock wool sandwich panel meets the requirements of the fire protection standard No. 33. The test results are as follows:) Thick rock wool sandwich panel R Thick rock wool sandwich panel Thick rock wool sandwich panel
) Good thermal insulation: The thermal insulation performance of rock wool sandwich panel is based on the performance of rock wool Thermal conductivity is based on .3/㎡ and is calculated based on the thickness of the rock wool core material in the corresponding proportion.
3) The sound absorption and heat insulation effect is significant:
Sound insulation: rock wool sandwich panel
It has a significant reduction effect on noise transmission, and is especially suitable for places where designated flights pass. In addition, after using rock wool roof panels, the indoor sound caused by the impact of rain and hail on the building's roof steel panels is also significantly reduced. Through testing, in accordance with the / and / standards, a sandwich panel with a density of /3 rock wool as the core material is selected. The sound insulation effect can reach R
Sound absorption: The rock wool sandwich panel also has an excellent attraction effect. Can absorb sound in a relatively wide frequency range. According to / standard
, the sound absorption performance level of rock wool sandwich panel reaches.B
