Rock wool A-grade fireproof insulation ultra-thin stone veneer
"Bangti" brand rock wool A-class fireproof and heat-insulating ultra-thin stone veneer is a new type of external wall insulation decorative composite board developed and produced by Shanghai Bangti Company. The sandwich insulation material uses waterproof rock wool, with high-quality alkali-resistant fiberglass cloth as the bone and the outer shell, and the outer shell is made of special inorganic polymer mortar to form a whole. The materials used are all inorganic products, which make the products meet the national Class A fire protection standards.
The reinforcing structure inside the box connects the wall surface of the insulation board and the exterior decorative stone to form a unique box-type reinforcing structure, and the integrated board is integrated with the building. At the same time, the company also uses a special special aluminum alloy special pendant to connect the integrated board to the wall. The unique installation of wet and dry hanging combined to ensure the safety of high-rise buildings.
Product introduction: Rock wool
Also known as rock wool, it is a kind of mineral wool. It is a natural stone, ore and other raw materials, which are melted in a cupola or other pool kiln (temperature below 2000 °C), and blown and quenched at a pressure of 50 atmospheres. Fibrous. Or by the method of twisting, the melt stream is dropped on the multi-stage rotary rotor, and the centrifugally short fibers are formed by centrifugal force.
Technical indicators: fiber diameter is generally 3 ~ 9 microns, bulk density 50 ~ 200 kg / m ^ 3, thermal conductivity at room temperature 0.029 ~ 0.046 W / m? open, below 0.1 ° ~ 0.145 W / m below 600 ° C, open, non-combustible, Not mildew, not awkward.
Main performance
1. Insulation performance: good thermal insulation performance is the basic characteristics of rock wool. Their thermal conductivity is usually between 0.03 and 0.047 W/(moK) under normal temperature conditions (about 25 °C).
2. Combustion performance: The burning properties of rock wool products depend on the amount of flammable binder. Rockwool itself is an inorganic silicate fiber, non-flammable. In the process of processing into a product, sometimes organic binder or additive is added, which will have certain influence on the combustion performance of the product.
3. Sound insulation performance: Rockwool products have excellent sound insulation and sound absorption properties. The sound absorption mechanism is that the product has a porous structure. When the sound waves pass, friction is generated due to the flow resistance, so that part of the sound energy is absorbed by the fibers. , hindering the transmission of sound waves.
Product form: Rock wool can be made into strips, belts, ropes, felts, blankets, mats, mats, tubes, plates.
