What are the classification methods for acoustic ceilings?

An acoustic ceiling is an ideal sound-absorbing decorative material. Acoustic ceilings have the advantages of sound absorption, environmental protection, flame retardancy, heat insulation, heat preservation, moisture resistance, mildew resistance, and high-cost performance. There are a variety of colors to choose from, which can meet the needs of different styles and levels of sound absorption decoration.

Here is the content list:

• According to the production materials, which types of acoustic ceilings can be divided?

According to the production materials, which types of acoustic ceilings can be divided?

①Wood: wooden acoustic ceilings are exquisitely processed according to the principle of acoustics and are composed of facings, core materials, and sound-absorbing thin felts. There are two types of wood acoustic ceilings: split-slot wood acoustic ceilings and perforated wood acoustic ceilings. ②Mineral wool: the surface treatment of mineral wool sound-absorbing board has various forms, and the board has a strong decorative effect. The surface-treated knurled mineral wool board, commonly known as "caterpillar", is covered with holes of different depths, shapes, and diameters. ③Fabric: fabric acoustic ceilings—the core material is centrifugal glass wool. Centrifugal glass wool, as an acoustic material that has been widely used all over the world for a long time, has been proven to have excellent sound absorption properties.

What types of acoustic ceilings can be divided into environmental protection grades?

The acoustic ceilings are installed on the base material, and the grade is divided according to the amount of formaldehyde emitted by the material of the base material. There are a total of E0, E1, and E2 grades, of which E0 is the highest level of environmental protection (also the European environmental protection standard), E1 Secondly, E2 formaldehyde emission is relatively highest. If used directly for indoor installation, E1 acoustic ceilings are qualified.

According to the structure, which acoustic ceilings can be divided into?

① Sound-absorbing wedge: the sound-absorbing wedge is a special acoustic ceiling used for a strong sound absorption field. It is made of porous (or fibrous) material and made into a cone or wedge-shaped sound absorbing body, which is strong and does not deform. The sound-absorbing wedge is suitable for a strong airflow environment. The main target is a high-quality anechoic chamber. It absorbs low frequencies more effectively, can eliminate standing waves, and meet the requirements of eliminating echo. The low cut-off frequency sound absorption coefficient is greater than 0.99. ②Loudspeaker: in addition to having all the functions of a flat sound-absorbing ceiling, the loudspeaker acoustic ceiling can also transmit sound waves from different angles through its three-dimensional surface, eliminating the blind spots in the sound wave diffusion process, improving sound quality, reducing pressure and weakening the treble To compensate for the bass. ③ Aluminum honeycomb perforation: the structure of the aluminum honeycomb perforated acoustic ceiling is a perforated plate and a perforated backplate, which are directly bonded with the aluminum honeycomb core through a high-quality adhesive to form an aluminum honeycomb sandwich structure.
