How to prevent sound mold?
1, sound raw materials mildew prevention, raw materials to prevent moisture, pollution, is the basis of mold risk control.
2, audio materials, semi-finished product turnover process pay attention to anti-mold:
2.1 Production materials should not be piled directly on the floor. They should be separated by pallets and more than 10CM away from the wall
2.2 For semi-finished products placed for more than 24 hours, moisture-proof and dust-proof measures shall be taken, protected with plastic film or bag, and used in sequence.
2.3. Keep the production environment clean. Do not bring food and other high pollution sources into the workshop.
2.4. The glue used in the production of wooden speakers, especially water-based glue, must be added in the glue special anti-mildew agent such as Xinke -02B and other products, because the glue is rich in grease, starch, protein and other organic matter, adding glue anti-mildew agent in the glue can effectively inhibit the microorganism in the glue, especially the propagation of mold, from the source to eliminate the growth of mold.
2.5, the box mildew prevention, the cabinet of the MDF mildew risk is the highest, it is best to spray a layer of mildew prevention paint (preparation: primer added a certain proportion of the new branch - anti-mildew agent, not painted MDF can be directly in the MDF brush a layer of wood mildew prevention agent new branch -M8, to prevent mold breeding in the box, to prevent mold spread to the drum circle and horn.
