🕙 2023-09-06 👆

After buying a car, many friends find that their car makes a lot of wind noise when driving, but they don't want to dismantle the car and install sound insulation cotton, so they want to install the so-called "sound insulation adhesive strip" on the Internet to alleviate the noise problem of the vehicle. So are car seals useful? Can it provide sound insulation and noise reduction?
The main function of the automobile sealing strip is to prevent dust and odor. As for the sound insulation and noise reduction, the effect is negligible. The noise isolation of cars is a systematic project, which can not be completely solved by adding sealing strips. Vehicle noise mainly comes from tire noise, wind noise and engine noise, which can not be solved by installing sealing strips. Therefore, it can be said that the so-called automobile sealing strips on the Internet are "IQ tax". Secondly, poor quality sealing strips are easy to age after exposure to the sun, and then directly stick to the paint surface, which will cause certain damage to the automobile paint surface.
Possible problems caused by installing the sealing strip
1. Rubber tube aging: the adhesive is not firm, and the sealing strip will fall off after a period of use, or even stick to the car, affecting the beauty of the car;
2. Impact on Aesthetics: after the sealing strip is installed, the door will become conspicuous. If the door is not large, it will appear large and wide, thus affecting aesthetics;
3. Blocking the water outlet: after installing the sealing strip, some water outlet holes will be covered. When it rains, the rainwater entering the door will not be discharged, which will lead to rust of the door metal and even water seepage in the vehicle.
Solution to abnormal friction sound of sealing strip
First of all, the relevant lubricant of the sealing strip can be used for lubrication, but many car owners say that this method is useless. Then you can use the door repair wax to repair, which can effectively make the sealing strip soft and elastic. It takes about 10 minutes to get the effect after applying it. If there is still obvious abnormal sound, and the sealing strip is still hardened and aged after repair, the door sealing strip with abnormal sound needs to be replaced, so that the abnormal sound can be eliminated.
