Color steel rockwool sandwich panel

Rockwool sandwich panel is a new type of fireproof panel with the strongest fire resistance among similar products such as EPS sandwich panel and PU sandwich panel. The core material produced from natural rock. Blast furnace iron ore slag is melted into silk at high temperature, and then solidified and formed. This panel meets the requirements of second-level fire protection in clean workshops, and is the most ideal decorative board for indoor ceilings and partitions.

Rockwool displays strong water absorption. It should be avoided to get wet during transportation, storage and installation, otherwise it will easily lead to degumming, swell and deformation of the composite board. If the surface steel sheet used in a humid environment for a long time, which will cause corrosion of the steel sheet.

Performance of  rockwool sandwich panel

1 - Fire resistance: Rockwool is a material that does not contain asbestos and freon, and its fire resistance is quite good. Generally, the fire resistance time of panels with thickness of 50mm, 75mm and 100mm can approximately reach 1H, 1.5H and 4H respectively.Performances of  rockwool sandwich panel

2 - Thermal insulation: Based on the thermal conductivity of rock wool λ = 0.043W / m2K. Because the core material shows outstanding heat preservation, compared with concrete slabs it has increased more than 5 times. This makes the use of rock wool sandwich panels to save air conditioning costs in hot areas and heating costs in cold areas.

3 - Light weight: Compared with clay bricks with the same thermal insulation performance, its weight is only about 1/19 of rockwool sandwich panel. It greatly reduces the external load of the load-bearing structure, and is convenient for installation and reduces transportation.

4 - Convenient and fast construction: The construction of rock wool sandwich panel is dry operation, the main work is to do a good job of connecting and fixing various bolts and spare parts. The on-site operation is minimized, and the construction safety is improved, that is. No need of senior installation workers, as well as, secondary decoration, greatly shorten the construction period.

5 - Seismic performance: Engineering practice has proved that under the action of seismic force, the sandwich panel is often in a normal working state due to its good seismic performance.

6 - Durability and decoration: The color of the coated steel sheet is customized, so that the user can choose the favorite color, and no other decoration is required. If both the inside and outside sheet of the rock wool sandwich panel use the coated steel sheet with such as PVDF, the using life can reach more than 20 years.

7 - Sound absorption performance: The sandwich panel with density of 100kg / m3 rock wool as core material is adopted, and the sound insulation effect can reach RW = 29 ～ 30dB.

Application


The color steel rockwool sandwich panel is suitable for where needs heat insulation and sound insulation, like baking rooms, paint rooms, industrial equipment, buildings, ships, etc. Meanwhile, it is suitable for ceilings and partitions of electronic clean rooms, purification rooms, workshops which needed explosion-proof and fireproof. The 50-150mm thickness rockwool insulation board is made of basalt and other natural ores as the main raw materials.

It is melted into fibers by high temperature, added with an appropriate amount of binder and solidified. Rockwool insulation board products are widely applied for the industrial building and construction that need the effect of thermal insulation and sound insulation .
