What’s Mineral Wool Board?
Mineral wool sound-absorbing board: It is made of mineral wool as the main raw material, starch as the main binder, and an appropriate amount of auxiliary agents and additives. It is processed through more than ten processes such as batching, molding and dehydration, generalization and drying, cutting and milling, fine processing, spraying, and packaging. It is a ceiling decoration material that integrates multiple functions such as thermal insulation, sound absorption, fire prevention, and decoration. It is a healthy, environmentally friendly, and recyclable green building material.
- Application
Mineral wool sound-absorbing panels are mainly used in conference halls, libraries, concert halls, high-end hotels, gymnasiums, hospitals, office buildings, production workshops and other places with sound absorption requirements.
Most mineral wool sound-absorbing panels are used as ceiling decoration materials, but they can also play a good role as wall decoration materials.
With the improvement of people’s quality of life, residents have their own “home theater” at home, and have new requirements for the sound absorption and decorative effects of home decoration. Therefore, mineral wool decorative sound-absorbing panels have become a popular material for residents’ home decoration and have gradually entered ordinary people’s homes.
Advantages of mineral wool board ceiling:
The competition in the ceiling market is fierce. The main decorative materials used for ceiling are mineral wool sound-absorbing board, paper plaster, aluminum gusset, PVC gusset, sauna board, etc. Compared with the above materials, the advantages of mineral wool board ceiling:
- Excellent decorative effect.
The surface treatment of mineral wool board is rich, and it can be made into various exquisite surface patterns, colorful flat roller patterns and reliefs, three-dimensional shapes, which have both classical beauty and fashionable atmosphere, and are truly refreshing. It is a good decorative ceiling profile.
- Antibacterial, anti-mildew, and good thermal insulation performance.
The thermal conductivity of mineral wool sound-absorbing board is very low. It is a good thermal insulation material, which can make the room warm in winter and cool in summer, and effectively save energy for users. Mineral wool board contains nano antibacterial agent, and its ultra-fine antibacterial agent can penetrate into the mineral wool board, so that harmful bacteria cannot hide. Its surface also has ethylene-based mildew-proof coating, which has mildew-proof effect.
- Sound absorption and noise reduction.
The main raw material of mineral wool sound-absorbing board is ultra-fine mineral wool fiber, with a density of 200-450Kg/m. Therefore, the interior of the mineral wool board is a three-dimensional cross-net structure with abundant through micropores, which can effectively absorb sound waves and reduce sound wave reflection, thereby eliminating or isolating noise and improving indoor sound quality.
- Safety and fire prevention
Since mineral wool is an inorganic material and will not burn, and the organic content in the mineral wool sound-absorbing board is very low, the mineral wool sound-absorbing board meets the flame-retardant B1 grade requirements, while some companies’ products can already meet the non-flammable A grade requirements. Mineral wool board does not contain asbestos, and perlite with fireproof function is added. Fire retardant is also added to the surface coating, which greatly improves the fireproof performance of mineral wool board.
- Green and environmentally friendly, air conditioning.
Mineral fiber board does not contain asbestos, is harmless to the human body, and is also added with rare earth inorganic composite materials, which can absorb and decompose toxic substances produced during the decoration process, and the active groups it contains can absorb harmful gases in the air, such as formaldehyde. Its microporous structure can absorb and release water molecules, so it can purify the air, regulate indoor air humidity, and increase the concentration of oxygen ions in the air, improving our living environment.
- Moisture-proof and insulating.
Because the mineral wool sound-absorbing board contains a large number of micropores and has a relatively large specific surface area, it can absorb and release water molecules in the air and regulate indoor air humidity. It can be said that the mineral wool sound-absorbing board is a kind of decorative board that can breathe. The main components of the mineral wool sound-absorbing board are mineral wool and starch, both of which are insulating materials, so the mineral wool sound-absorbing board is an insulating decorative material.
- Easy to cut and easy to decorate.
Mineral wool sound-absorbing boards can be sawed, nailed, planed, and bonded, and can be cut with a general wallpaper knife, so no noise will be generated during cutting. It has a variety of hanging methods such as flat pasting, plug-in pasting, open frame, and hidden frame, which can combine decorative effects of different artistic styles. Home users can decorate by themselves and let them freely use their imagination, which is also in line with the trend of modern people who are happy to decorate their own space by themselves.
- Good impact resistance.
The interior of the mineral wool board presents a three-dimensional cross-net structure, and the coating uses a composite fiber and a net structure. The mineral wool board has a stable structure, which greatly improves its impact resistance.
How to distinguish the quality of mineral wool board
- Check the material of mineral wool board
The production of mineral wool board should start from the raw materials. Good mineral wool board must also use high-quality mineral fiber wool; and the slag used by some small manufacturers in the market to produce mineral wool board is natural slag. It is easy to find that the mineral wool board made by them contains impurities, uneven weight, and easy to deform. When we identify mineral wool board, it is best to observe the quality of mineral wool from the side of the exposed mineral wool board in detail, whether it is uniform, whether the color difference of mineral wool is consistent, etc. This is the basic method to distinguish the quality of mineral wool board.
- Check the surface of mineral wool board
Mineral wool board will be surface treated during production. Regular manufacturers will polish and spray the surface of mineral wool board. This is where the quality value of mineral wool board is shown. Because the cost of latex paint used for spraying is different, some manufacturers will choose relatively cheap and low-quality latex paint for spraying, and the spraying process is relatively simple; some mineral wool board manufacturers even use puttying to make the surface of mineral wool sound-absorbing board smooth and clean to cover the impurities of the mineral wool board. The surface spraying treatment and back coating treatment of the mineral wool board used by Longpai mineral wool board are strictly up to standard, which better improves the performance and surface beauty of the mineral wool board. The surface of the better mineral wool board is not only sprayed, but also frosted, coated, etc., which further improves the grade and performance of the mineral wool board. Therefore, another criterion for judging the quality of mineral wool board is to check whether the color difference of the surface spraying treatment is consistent, whether the back coating meets the standard, whether there will be sticky mineral wool, whether there are protrusions on the surface, etc.
- Check the shape of the mineral wool board
The common mineral wool board we have is 600*600 white, and the ceiling shape that can be made is relatively simple, while high-quality mineral wool board ceilings can also be made into many shapes. The surface of mineral wool board can be processed in many colors and shapes, such as black mineral wool board, corrugated mineral wool board, etc. High-quality mineral wool board can be made into staggered shapes, giving customers more choices. Small mineral wool board manufacturers do not have the production and design capabilities of such mineral wool boards.
- Check the performance of mineral wool board
The performance of mineral wool board is the simplest standard to reflect the quality of mineral wool board. On the sample label of mineral wool board, the general manufacturer will attach the information of the corresponding mineral wool board, including its sound absorption performance index, fire performance index, sound insulation performance index, moisture resistance performance index, etc. Generally, in the engineering ceiling, the mineral wool board manufacturer will issue a performance test report of the mineral wool board of the corresponding quality product to finally determine the quality of the mineral wool board and whether it can meet the required use standards.
In the selection of mineral wool board, we should not only look at its price, but also look at the quality of the mineral wool board product. Only good mineral wool board is more suitable for us to use. Among the qualified and suitable mineral wool boards, it is best to choose the one with higher cost performance.
