FRP sound-absorbing panel is a kind of sound-absorbing material composed of glass fiber and organic polymer materials, and its unique sound-absorbing performance has been widely used in acoustic engineering. The formation of FRP acoustic panels needs to go through the following steps:
1. Preparation of raw materials.
The raw materials of FRP sound-absorbing panels mainly include glass fiber, organic polymer materials, fillers, additives, etc. The quality and ratio of these raw materials have a crucial impact on the performance of FRP acoustic panels. When preparing raw materials, it is necessary to select and proportionate according to the production process and performance requirements to ensure that the produced FRP sound-absorbing panels meet the design requirements.
2. Stir and mix.
Raw materials such as glass fiber, organic polymer materials, fillers and additives are mixed together according to a certain ratio, and fully stirred through a mixer to make various raw materials fully mixed evenly. During the mixing process, it is necessary to pay attention to controlling the mixing time and speed to avoid uneven mixing or excessive stirring.
3. Dipping and weaving.
The mixed raw materials are impregnated so that they are evenly coated on the fiberglass cloth, and then woven and molded. When dipping glue, it is necessary to pay attention to controlling the concentration of glue and the amount of coating to ensure the adhesion and soaking effect of the glass fiber cloth. When weaving, it is necessary to ensure the density and tension of the yarn to ensure the strength and sound-absorbing performance of the FRP sound-absorbing board.
4. Heating and curing.
The woven FRP acoustic panel is placed in a heating furnace for heating and curing. The heating temperature and time need to be selected according to different production processes and raw materials to ensure that the material is fully cured and maintains good performance. During the heating and curing process, it is also necessary to pay attention to controlling the atmosphere in the furnace to avoid oxidation or burning.
5. Processing and molding.
The heated and cured FRP sound-absorbing panels are cut, cut, polished and other processing to obtain the shape and size that meet the design requirements. During the machining process, attention needs to be paid to controlling the accuracy and quality to avoid damage or deformation. At the same time, surface treatment is also required according to different application scenarios to improve the weather resistance and decoration of FRP sound-absorbing panels.
6. Quality inspection and packaging.
Finally, the quality inspection and performance test of the processed FRP sound-absorbing panel are carried out to ensure that it meets the design requirements and relevant standards. Quality inspection includes visual inspection, dimensional measurement, performance testing, etc. FRP acoustic panels that have passed the quality inspection can be packaged for transportation and storage. When packing, it is necessary to take measures such as moisture-proof and shockproof to ensure the safety and quality of the product.
To sum up, the formation of FRP sound-absorbing panels needs to go through steps such as raw material preparation, stirring and mixing, dipping and weaving, heating and curing, processing and molding, quality inspection and packaging. In the production process, various process parameters and quality requirements need to be strictly controlled to ensure the performance and quality of the product.
