WPC Foam Board has brought several vital influences in our production and life, what's the sound-absorbing material performance of the WPC Foam Board? Next, allow us to take a glance.

Here is that the content list:

• Structural properties of wood-plastic sound-absorbing materials

• The acoustic performance of wood-plastic sound-absorbing materials

Structural properties of wood-plastic sound-absorbing materials

The WPC Foam Board sound-absorbing board with micro-holes, wedge, cavity, and slot structure is created of foamed material with microporous structure and is supplied with a base material bottom with many spaced supports and several other wedge structures. The highest of the substrate, the aspect of the substrate with the slot, and also the plug-in finish such as the slot square measure at the opposite finish of the aspect of the substrate, therefore determination the present scenario of poor decoration, high cost, low strength, and sophisticated construction of wood-plastic sound-absorbing panels. A WPC Foam Board composite multifunctional sound-absorbing board, together with PVC wood-plastic foam board, veneer ornamental layer, cork veneer sound-absorbing layer, and a truncated conelike sound-absorbing hole is provided on the board, and also the back of the wood-plastic substrate is provided. There square measure flexuous grooves. The wood-plastic composite board has functions like sound absorption, mechanical properties, and decoration. The wood-plastic composite sound-absorbing profile has sound-absorbing holes, sound-absorbing cotton, and a set structure of the plug-in finish groove. This type of sheet has a low price, is environmentally friendly flame retardent, is gorgeous and sturdy, and has sensible sound absorption results. Additionally, because of the setting of the plug-in finish, groove, and glued finish of the WPC Foam Board, the installation is incredibly convenient. Analysis on the poor sound absorption performance of wood-plastic composites at low and mid-frequency, results show that for the air cushion system composed of wood-plastic composites and air layers, an exact cavity and air layer square measure left behind the WPC Foam Board Distance will effectively improve the low-frequency sound absorption performance of wood-plastic composites.

The acoustic performance of wood-plastic sound-absorbing materials

The sound insulation performance of the WPC Foam Board was ready with completely different content of wood flour, coupling agent, and barium sulfate. The results show that: beneath the condition of comparable surface density, the mesh variety and content of wood flour in the main have an effect on the sound insulation of frequency above 125Hz, and also the sound insulation result of coupling agent isn't obvious; once adding barium sulfate, the thickness, and surface of the fabric square measure reduced. Supported similar density, PVC plastic panels and wood-plastic composite panels with identical formula have higher sound insulation performance at frequencies above 2000 Hertz. The result of various veneer materials on the sound absorption performance of PVC foam wood-plastic floor. Completely different materials square measure glued on the surface and back of the WPC Foam Board through the recent pressing method, and also the sound coefficient is tested by the stationary wave tube methodology. The results show that PVC wood-plastic floor Foam flooring features abound sound coefficient within the low-frequency vary, and completely different materials on its surface and back can improve the low-frequency sound absorption performance of wood-plastic flooring. Supported the law of quality and sound scattering theory, numerical analysis was accustomed study the sound physical phenomenon within the insulating layer of wood-plastic stuff full of precipitated carbonate, and a physical model was established to investigate the transmission of wood-plastic composite materials with completely different mass ratios of precipitated carbonate. Sound loss, the corresponding sound transmission loss equation comes. The results show that the sound transmission loss of the wood WPC Foam Board will increase with the rise of the sound frequency and also the mass magnitude relation of precipitated carbonate, however, the result isn't obvious within the low-frequency vary. Wood-plastic composite materials don't have glorious sound absorption performance in terms of their material properties. However, the way to enhance the sound absorption performance of WPC Foam Board merchandise will talk to the composite properties of wood sound-absorbing materials and alternative sorts of sound-absorbing materials to maximize the bottom improvement of the sound absorption performance of wood-plastic composite materials is that the analysis direction of wood-plastic sound-absorbing materials. In step with the characteristics and desires of wood-plastic merchandise, targeted style and manufacture of WPC Foam Board sound-absorbing materials are the long-run development trend

HANGZHOU JIAYING TRADE CO.LTD, is AN enterprise desegregation R&D, production, and promotion. It in the main provides high-quality PVC boards, Foam boards, brocaded boards, and alternative ornamental boards. Our company is found in Hangchow, Zhejiang, a notable historical town in southern China. The notable Venetian traveler represented Hangchow as "the town of Paradise, the foremost stunning town within the world". it's on the point of Shanghai, one hour by train or two hours by high speed, and solely twenty minutes drive from Hangchow International airdrome. we've got three factories in Hangzhou and Shaoxing, every of that takes two hours to load product from Shanghai and Ningbo ports.

The above is expounded to the performance of WPC Foam Board sound-absorbing materials. If you're fascinated by WPC Foam Board, our website is https://www.hzpvcboard.com/.
