The difference between Debao vibration-proof board and sound-proof cotton is: 1, and the properties are different: the vibration-proof board is a kind of flaky elastic adhesive, which is made of the same material as chewing gum, and can effectively inhibit metal vibration and block metal sound transmission, and the surface is pasted with aluminum skin to inhibit damping and enhance the effect. Sound insulation cotton is a soft sponge-like substance, which can effectively block the propagation of sound waves in the air and play the role of sound insulation and sound absorption.
2, the effect is different: the vibration stop plate can stop vibration, and it is also the first barrier of sound insulation, but it has a bad effect on absorbing sound waves in the air. Sound insulation cotton has better effect.
3. Different functions: the shock absorber can inhibit the vibration of steel plate, block noise with high density and high efficiency, enhance the toughness of steel plate and improve safety.
The main function of sound insulation and sound absorption cotton is to block low-density noise, absorb noise and inhibit noise from radiating outward.

Precautions:
Through the law of commodity value, we know that the value of commodity is determined by social labor time, the value of product depends on the price of product, and the relationship between supply and demand of product affects the price of commodity; Prices always fluctuate around value. Therefore, the product price is related to the production process, work efficiency, material composition, volume density, environmental protection function, fire rating and so on.
The product is fluffy material, with a large number of small holes connected inside and outside, uniform texture distribution, strong vertical and horizontal ability, soft feel and smooth surface; When purchasing, it is recommended to buy incombustible or flame retardant materials, which meet the fire protection standards; It has certain environmental protection function and protects people's physical and mental health.
