PP melt blown cotton sound absorber filter element

PP melt blown cotton sound absorber filter elementIt is a pneumatic or hydraulic system component that integrates filtering, noise reduction, and exhaust functions. It is commonly used in the exhaust ports of pneumatic equipment to reduce exhaust noise and prevent external pollutants from entering the system.

• structural characteristicsUsually a cylindrical hollow structure, the pore wall is composed of PP fiber layers, and the fiber layers are equipped with curved micro channel structures for noise reduction. One end is equipped with a fiber cotton bottom cover, which is fixed by hot melt sealing welding, and the other end can be equipped with soundproof cotton, which is sealed and fixed by high-temperature glue.

• manufacturing processFiber grade polypropylene resin raw material is melted at high temperature by a screw extruder and sprayed into fiber filaments. The fiber filaments are cooled by air and formed into cylindrical products on special equipment, namely PP melt blown cotton muffler filter element. By controlling the diameter of the sprayed fiber filaments, the size of the noise reduction holes can be adjusted, thereby adjusting the noise reduction effect and air resistance.

• performance advantage

• Good noise reduction effectThe curved microchannel structure can effectively absorb and dissipate sound wave energy. In the noise range of 125-4000Hz, when used in conjunction with sound-absorbing cotton, the sound absorption coefficient can reach 0.94.

• Excellent filtering performanceFeaturing a three-dimensional microporous structure and multi-layer gradient design, it can effectively intercept particle impurities, with a filtration accuracy of up to 0.1 μ m-100 μ m. At the same time, it has a large pollutant holding capacity, which can extend its service life.

• Strong chemical stabilityPolypropylene material is resistant to acid and alkali corrosion, suitable for various chemical environments, non-toxic and odorless, and meets food grade safety standards.

• Low pressure differential operationThe optimized pore structure reduces fluid resistance, reduces energy consumption, and enables the filter element to maintain a low pressure drop during operation.

• PP melt blown cotton sound absorber filter elementApplication fieldMainly suitable for use in mufflers of diaphragm pumps and other equipment, used to reduce the noise generated during equipment operation. Meanwhile, due to its excellent filtering and noise reduction performance, it can also be applied to some occasions that require certain air or fluid quality and require noise reduction treatment, such as industrial ventilation systems, air purification equipment, etc.
