Problems solved by technology

[0002] In the field of modern building ceilings, decorative sound-absorbing coatings are applied in the factory, and seams cannot be avoided, the decorative effect is poor, and the appearance is affected, and glass wool fibers / rock wool fibers are easy to float out of the seams, causing fiber pollution. At the same time, the strength of the glass wool board / rock wool board is poor, and the board is easy to bend and sag. If the situation is serious, it will cause falling, causing accidents and disasters, and the sound absorption effect is often not obvious
[0003] Moreover, in use, the particularity of the sound-absorbing material often results in poor alkali resistance and poor compatibility with general decorative coatings, which is likely to cause harm to the sound-absorbing material.
