Anping Hengai gives you a trick to identify the road sound barrier making materials.

People who often drive on the expressway will find that the road sound barrier is constantly improving with the technology, not only the style is diverse, but also very beautiful, and more importantly, it satisfies the practicality. The road sound barrier manufacturers provide more for people. Convenient.

In order to make the road sound barrier more beautiful, a transparent road sound barrier is usually used. Driving at high speed for a long time, people are more prone to fatigue, and through this transparent road sound barrier, you can see the scenery along the way, the higher transparency, it can bring a lot of visual enjoyment. Well, then, you know what kind of road sound barrier is high quality. Anping Hengai, as a road sound barrier manufacturer, has a wealth of experience and can be summarized as a good road sound barrier can not be separated from good sound insulation materials, Come down to Anping Hengai for everyone, how to identify sound insulation materials.

1, touch by hand, good sound insulation material hand touch hard and heavy. The amount of sound insulation follows the principle of quality law, that is, the greater the unit density of the dense cloth, the greater the sound insulation. The areal density is proportional to the amount of sound insulation. Therefore, the sound insulation material of the same unit area has a higher density, a larger mass, and a better sound insulation amount.

2, measuring elasticity, outstanding elasticity can reduce the sensation of hard plates due to sound waves. For example, the simple method of checking the elasticity of the soundproof felt is to cut the soundproof felt into strips of two or three centimeters wide, and then pull it with both hands. If it can be simply stretched and slackened and the length is restored, it is a good soundproof felt.

3, test tolerance, strong resistance is another specification of sound insulation materials.

4, try to pull, good sound insulation materials, if you do not rely on knife and scissors, etc. is not easy to tear.

Therefore, in the process of using the road sound barrier, it is necessary to do a good job of protection. For example, when constructing a road sound barrier manufacturer, it is necessary to pay attention to the condition that the surface is clean and dry, and it is necessary to clean it regularly, especially in the case of Where the pollution is serious or the corrosion is relatively large, it is necessary to protect the road sound barrier several times in order to prolong the service life. In addition, if you want to have higher transparency, you need to clean up the dust on the road sound barrier as soon as possible.
