& Shijiazhuang Broadcasting School Wall Decoration Environmentally Friendly Sound-Absorbing Materials Manufacturer 1. Product structure:
, Base material: high-density board, flame-retardant board, glass-magnesium composite board, ceramic aluminum board, polymer board, etc. Commonly used base materials are Ordinary substrates, environmentally friendly substrates, fireproof substrates, and composite substrates.
, Decoration: melamine, natural veneer, fireproof board, spray paint, metal surface, etc. Decoration is usually flat, pitted, embossed surface, melamine coating? Please choose according to the company's color card? Real wood veneer veneer? Wood veneer, paint and color can be selected according to customer requirements. Sound-absorbing felt: The color is black and is pasted on the back of the sound-absorbing board to provide fire-proof and sound-absorbing properties.
The grooved wood sound-absorbing board is a slit resonance sound-absorbing material with grooves on the front and perforations on the back of the density board. Often used for wall or ceiling installation.
, core material? or thick plate. Wooden sound-absorbing panels are usually made of second-grade boards with a density of /, and first-grade boards can also be used according to user requirements. High-density board, environmentally friendly MDF, flame-retardant MDF (flame-retardant grade reaches B)
. Introduction to combustion grade: Combustion performance refers to all physical and chemical changes that occur when building materials burn or encounter fire. , this performance is measured by the ignition and flame propagation properties of the material surface, heat generation, smoke generation, carbonization, weight loss, and the production of toxic products.
my country's national standard B divides the combustion performance of building materials into the following levels. Grade: non-combustible building materials Grade B: flame-retardant building materials Without sound absorption, the sound absorption effect is achieved by changing the structure of the material.
. Cross-sectional structure of wooden sound-absorbing panels: According to the upper and lower structures, they are divided into: facing, MDF, and black felt.
2. Product Specifications
Length: Width: Thickness:,
(Allowable tolerance: width
is +., length is +.) But it can also be made according to customer requirements, but the loss It is large and very troublesome. Generally, we will recommend customers to use regular size thickness, which is more commonly used in the market. When customers order large boards, they need to be made according to the number of strips in the entire large board.
&Imposition: The long sides of the slats are made into angular tongues and notches for splicing according to actual needs.
