Why Is Mineral Wool Board So Popular?

Do you know all the basic knowledge of these mineral wool boards?

The mineral wool decorative sound-absorbing board is referred to as a mineral wool board. It is made of granular cotton (made by smelting industrial waste and melting at high temperature) as the main raw material, adding other additives, and going through the processes of batching, forming, drying, embossing, coating, cutting, etc. Processed.

The question is, why is the mineral wool board loved by many people? After reading its features, you should understand.

· Sound absorption and noise reduction

The mineral wool board is a kind of porous material, interwoven into countless micropores by fibers, sound waves hit the surface of the material, part of it is reflected back, the part is absorbed by the board, and part of it enters the back cavity through the board, which greatly reduces the reflected sound. Effectively control and reduce indoor reverberation time. NRC is a parameter indicating the sound absorption performance of a material. The NRC of the mineral wool board is generally between 0.5 and 0.7, and the NRC of the high sound-absorbing mineral wool board can reach 0.85, which is unmatched by other ceiling materials.

· Sound insulation

In public places, it is not only necessary to absorb the noise in the environment, but also to block the noise outside the environment. The general mineral wool board does not have sound insulation. The mineral wool board processed by special technology has a sound insulation layer on the back, which can effectively cut off the upper noise and create a quiet indoor environment.

· Fireproof

Fire resistance is the primary concern in the design of modern public buildings and high-rise buildings. The mineral wool board is made of non-combustible granular cotton as the main raw material. It will not burn in the event of a fire, which can effectively prevent the spread of fire. Moreover, due to its small deformation and long fire resistance time, it can fully extend the escape time and is the most ideal fireproof ceiling material.

· Moisture-proof

High-quality mineral wool boards have moisture-proof properties, and will not be deformed or moldy after long-term use. For example, mineral wool boards with moisture-proof coefficients of RH85, RH90, and RH99 respectively represent the ability to resist deformation in an environment with a relative humidity of up to 85%, 90%, and 99% and room temperature below 40°C (104°F). The higher the number, the better the moisture resistance.

Disadvantages of the mineral wool board:

1) The sound absorption and sound insulation effect of the sound-absorbing board of the mineral wool board ceiling often need to reduce the density, make it hollow, or punch holes. These methods will significantly reduce the strength of the mineral wool board and cause easy damage during hoisting.

2) The main surface of the sound-absorbing board of the mineral wool board ceiling is white, which is susceptible to yellowing due to the influence of other volatile solvents. It is recommended to decorate and install it last.

3) The color difference problem is more prominent due to the uneven spraying process of the mineral wool board ceiling. You must compare the color when you buy it. Sand-spreading boards and embossed boards often lose dust and are not recommended for use in humid environments.

What are the common classifications of mineral wool boards?

Different manufacturers have different processing techniques for the surface of the mineral wool board. There are four mainstream processing methods: roll flower, pinhole, sandblasting, and film coating. These processing methods cause major differences in appearance and performance.

03.

What are the fixing methods for the ceiling of the mineral wool board?

The mineral wool board needs to be hoisted by steel keel. According to whether the keel frame is exposed, it can be divided into three basic hoisting methods: exposed frame, concealed frame, and light-dark frame. On this basis, various hoisting systems defined according to different decoration styles are extended.
