What is the difference between rock wool composite board and rock wool board?

Recently, it is often heard that rock wool composite board and rock wool board are mentioned. I wanted to think, these are rock wool board. The products are the same, but are the names different? So I found the detailed information. Only to find that they are very different, let's share it with you.

The common feature of rock wool composite slate and rock wool board is that rock wool has excellent characteristics such as fire prevention, heat preservation, and easy cutting. It is also the most commonly used material for building sound absorption. In the rock wool board industry insulation construction process, must be careful. At present, the main key of the external wall composite rock wool board is the wall structure layer, the insulation layer and the decorative layer with distinct function.

rock wool composite board

Rock wool composite board is covered with a layer of cement on the surface of rock wool board. The difference is that the construction of rock wool composite board saves the workers water. To tell the truth, the current rock wool composite board is a new type of fire insulation material. According to natural basalt it is made from melting and spinning. When used indoors and outdoors, it is an excellent building fireproof material. This is the origin of the exterior wall composite rock wool board. The composition of ordinary rock wool board is obviously different. It is made of slag wool. Made, its chemical stability is poor, the time is too long, there is no insulation effect, shoddy manufacturing has been eliminated by the society.

Because the surface of the exterior wall composite rock wool board is not decorative, there will be scattered fibers, so it must be used in concealment. Now the rock wool board can also be used outdoors, its heat preservation effect is lasting, especially with fire prevention effect. As we all know, fires have occurred frequently in recent years, and the country has also strongly recommend the use of rock wool composite board fireproof materials! Although ordinary rock wool has fire resistance, it has fundamentally become an outdated product, and the construction industry needs more high-quality rock wool. Replace the cotton plate. This shows that the appearance of the composite rock wool board meets the requirements of the times. These excellent properties make the development of exterior wall rock wool board re-enter a new development process.

Preparation before construction of external wall rock wool board

Exterior wall rock wool board is widely used in buildings. It can not only ensure the indoor temperature, but also effectively prevent building fires. Enter the small series to introduce to you what preparations should be made before the construction of the external wall rock wool board?

Preparation before construction of external wall rock wool board:

1. The leveling layer of the foundation wall has been completed and reached the quality standard. Exterior wall insulation board, fireproof isolation belt and supporting materials are in place.

2. Both sides of rock wool are coated with interface agent. Due to the strong hydrophobicity of rock wool, the adhesion with polymer glue is not strong. In order to improve the adhesion of rock wool and the base wall, it can be treated with interface agent before construction, and the rock wool can be brushed. After coating the interface agent, the tensile strength with the base wall can reach more than 0.1MPa.

3. Special binder for rock wool mixing: Pour 25kg bonding mortar into a clean container and stir while adding materials. The polymer cement is preferably mechanically stirred at a 400 r/min speed until the slurry does not require the addition of water and other additives and is used up within one hour.
