The inorganic thermal insulation material rock wool board is made of basalt and other natural ore as the main raw material. The rock wool board is melted into fiber by high temperature, added with appropriate amount of binder, and solidified and processed. Rockwool board products are suitable for thermal insulation and sound insulation of industrial equipment, construction and ships. Let's talk about the advantages and disadvantages of the inorganic thermal insulation material rock wool board.
The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties. It is mainly used for thermal insulation and sound insulation of building walls and roofs; fire protection and noise reduction of building partitions, firewalls, fire doors and elevator shafts,
Features:
1. Rock wool belongs to inorganic thermal insulation material. It is made of iron ore slag as the main raw material. It is melted and cooled by high pressure steam. It has light weight, small thermal conductivity, good elasticity, non-combustible, no sputum, no decay. The advantages of chemical stability. It also has excellent sound insulation properties.
2. Rockwool sandwich panels are widely used in various fireproof and soundproof places in addition to the general movable structure for thermal insulation.
Rock wool board disadvantages:
1. Rock wool board can not replace the slope, you need to find the slope.
2. The water absorption rate is large, and the water is easily accumulated in the rock wool board, and the weight of the heat insulation layer is increased for a long time, resulting in the insulation layer falling off and the repair rate being high.
3. The process is complicated and the construction period is long.
