What to do if the sound system gets moldy? Nantong Boda told you!

      The main components of the audio system include: flocked fabric, fiberboard, PVC veneer, paint, eardrum, glue, speakers, and other materials. The main areas where mold grows are: the fiberboard, flocking cloth, and the location of the trumpet drum inside the box. According to Nantong Boda Biochemical Co., Ltd.'s years of understanding of audio production customers.

The main reasons for the growth of mold in the audio system are summarized as follows:

        1. The medium fiber board used in the sound box is relatively easy to absorb moisture;

        2. MDF materials are becoming increasingly environmentally friendly and do not contain DMF;

        3. The inside of the box is relatively dark, which can easily trap bacteria and mold;

        4. The paper material of the eardrum is relatively easy to absorb moisture;

        5. The paper of the tympanic membrane is composed of fibers, providing nutrients for mold;

        6. The flocked fabric used in the audio system is easy to absorb moisture;

        7. The warehouse where audio is stored has high humidity.

How can sound systems prevent mold?

        1. The mold prevention of audio raw materials, as well as the prevention of moisture and pollution, are the basis for controlling the risk of mold formation.

        2. Pay attention to mold prevention during the turnover process of audio materials and semi-finished products:

             2.1 Production materials should not be directly stacked on the floor, but should be separated by pallets and placed more than 10cm away from the wall

             2.2. For semi-finished products that have been stored for more than 24 hours, moisture-proof and dust-proof measures should be taken, protected with plastic film or bags, and used in sequence.

             2.3. Maintain a clean production environment, and do not bring high pollution sources such as food into the workshop. Operators in key positions are not allowed to operate with wet hands.

             2.4. For the glue used in the production of wooden speakers, especially water-based glue, special mold inhibitors such as Xinke-02B must be added to the glue. As the glue is rich in organic substances such as oil, starch, and protein, adding mold inhibitors to the glue can effectively inhibit the growth of microorganisms, especially mold, in the glue and prevent the growth of mold from the source.

             2.5. Anti-mold measures for the box body. The risk of mold on the MDF inside the box is the highest, and it is best to spray a layer of anti-mold paint (preparation: add a certain proportion of anti-corrosion and anti-mold agent to the primer, and directly apply a layer of wood anti-mold agent Xinke-M8 on the MDF without painting to prevent mold from growing inside the box and spreading to the drum and horn.
