1、 Regular inspection
1. Surface inspection: Regularly inspect the surface of small sound-absorbing spikes for damage, stains, or dust accumulation. If there is, it should be cleaned in a timely manner to maintain the sound absorption effect of the sharp edge.
2. Check the structure: Check whether the structure of the spikes is stable, especially for those installed on walls or ceilings, to ensure that they have no signs of loosening or falling off.
 
2、 Cleaning methods
1. Surface cleaning: For fabric spikes, a soft bristled brush or vacuum cleaner can be used to gently remove dust and impurities from the surface. For metal spikes, a clean cloth can be used to wipe the surface.
2. Deep cleaning: If there are stubborn stains on the surface of the wedge, a neutral cleaning agent can be used for cleaning, but be careful not to let the cleaning agent penetrate into the inside of the wedge to avoid affecting its sound absorption performance.
 
3、 Environmental control
1. Temperature control: Avoid placing small sound-absorbing wedges in extreme temperature environments, as high or low temperatures can cause damage to the material of the wedges.
2. Humidity control: Maintain appropriate humidity and avoid excessively humid or dry environments. An excessively humid environment may cause the sound-absorbing material inside the spike to become damp, affecting its sound-absorbing effect; An excessively dry environment may lead to embrittlement of the sharp material.
 
4、 Avoid damage
1. Avoid collision: When handling or installing small sound-absorbing spikes, be careful and handle them gently to avoid collision or compression, so as not to cause damage to the spikes.
2. Avoid sharp objects: Do not use sharp objects to touch the surface of the sharp edge, in order to avoid scratching or puncturing the outer material of the sharp edge.
 
5、 Regular replacement
Although small sound-absorbing wedges have a longer service life, their sound-absorbing performance may gradually decline over time. Therefore, it is recommended to conduct a comprehensive inspection of the spikes at regular intervals (such as every year or every two years). If it is found that the sound absorption effect has significantly decreased or the spike material has aged severely, a new spike should be replaced in a timely manner.
 
Through the above maintenance measures, the service life of small sound-absorbing wedges can be effectively extended, ensuring that they always maintain good sound-absorbing effects.
