WPC Foam Board Is The Way To Improve Sound Performance

　　Compared with the sound absorption performance of different wood composite materials, the sound absorption performance of wood plastic composite materials has excellent low-frequency absorption performance, however, the high-frequency absorption performance is poor, so it can be improved and improved in the way of actual engineering decoration. The high-frequency absorption properties of wood-plastic composites are critical to their promotion and applications. By inducing and analyzing the analysis results of different wood composite sound absorbing materials, by foam method, retained cavity method, honeycomb structure composite method, adhered decorative layer method, superimposed wood hole method, superimposed cavity method, superimposed The sound absorption performance of the wood-plastic material is increased. styles and different ways. The sound-absorbing impact of wood-plastic composites will additionally increase the price of their stacking. What is the strategy of the WPC foam board to absorb sound material? Next, let's follow our glance at the GEGE PVC Sheet factory.

　　foam method

　　This WPC foam board is prepared by adding a foaming agent to the wood plastic, which can reduce the density of the fabric, reduce the value of assembly, and create bound air-tight pores within the fabric, while its dominant form, composition, and density will improve the impact of the impact. The fabric is resistant and tough to a definite degree, so WPC foam boards are used in wider cases.

　　Preserved cavity filling method

　　Once in the wood plastic sound-absorbing board, the cavity-filling method is mainly to leave the obvious cavity behind the WPC foam board. Typically, the length of retention is greater than thirty centimeters. Once the cavity is created, the sound travels through the wood-absorbing panels. Once the sound waves and rigid materials are reflected and absorbed, most of the event sound energy is dissipated to engage low-frequency sound waves. The wave tube method was used to examine the sound coefficients of wood-plastic sound-absorbing panels at disparate perforation rates and cavity depths. At the two-thirds and third-perforation rate conditions, the absorbed sound coefficient initially increases with cavity depth. Then fall in the state of the perforation rates of June 6 and September 11, 1944, the sound coefficient of absorption will increase as the cavity depth will increase. Cavity-absorbing panels behind WPC foam boards may also be stuffed and adhered to bound high-frequency sound-absorbing materials such as inorganic sound-absorbing materials (glass wool, rock, rock, slag wool, etc.), damaged wood-plastic Composite materials, and inorganic sound-emitting materials. The composite preparation of wood-plastic composites realizes the full-frequency absorption performance of wood-plastic composites. The effect of the kind of inorganic fibrous material stuffed in the cavity filling method on the sound absorbing performance of WPC foam board sound absorbing panels, additional analysis is desired.

　　Honeycomb structure composite method

　　The honeycomb structure has excellent properties such as being lightweight, simple installation, shock absorption, and noise reduction. The honeycomb structure is placed on the back of the wood-plastic composite board to make a composite structure so that the cavity or filling material behind the WPC foam board is divided into many closed sub-spaces, so the square characteristics of the honeycomb structure will not conform to its characteristics. Enhanced confinement and reflection of sound waves to act like the sound-absorbing structures of Hermann von Helmholtz resonant cavities. This composite structure will improve the sound absorption performance of the WPC foam board in the low-frequency band, thereby enhancing the general sound absorption performance of the wood-plastic composite structure.
