In automobiles, seals improve airtightness and prevent wind and rain from intruding into the compartment. Once the sealing strip is deteriorated due to aging, it will cause the compartment to leak rain, increase the wind noise of the car, and it is easy for the vehicle body to rust when it leaks. For automobiles, we must choose sealing strips produced by high-end sealing strips. Seal strips are an important part and must be regularly checked and maintained. The first is to check whether the seal has large cracks and breaks. If the seal breaks or there is a large crack, it can be repaired with an adhesive. In particular, using adhesives for sealing tapes, it is easy to repair large cracks in the sealing strip. Of course, if the sealing strip is seriously damaged or the sealing strip is aged to a large extent, it is better to replace the new one. It is not difficult to change the sealing strip, but if you want to do better, please do it again. The routine maintenance work of the automobile weatherstrip mainly includes the following items: First, the car detergent is used for cleaning, and after cleaning, a layer of high-permeability protective agent is applied to prevent the aging of the weatherstrip. In addition, the gaps between the sealing strips are easily filled with sand and dust, causing rust. For this purpose, dust and dust should be removed with a brush. The sealing strip is an important component in the doors and windows. The sealing strip is a powerful measure to ensure the airtightness, watertightness, sound insulation and other aspects of the doors and windows. It is also a reliable guarantee for the safety of the glass in the doors and windows after external force. Since the weather strips are exposed to sunlight and sunlight, shrinkage, aging, and deformation occur. Therefore, the sealing strip must not be allowed to work under tension, and the sealing strip should be kept free. In order to hold the glass tightly, the sealing strip is often pulled too tight during the installation process to ensure that the sealing strip is in a tensile deformation state. Practice has proved that due to the installation of the sealing strip under tension and deformation, the sealing strip has come off, pulled off, and cracked. For this reason, when installing, the length of the sealing strip is longer than the length of the assembly side of the door and window, the slope is cut off at the corner, and it is firmly bonded with the adhesive, leaving enough expansion and contraction margin. We all know that when a car is driving at high speeds, there will be very large friction between the air and the car. If the car body is tightly sealed, high-pressure gas will easily pass through the gap (holes in the installation pipeline, rusted cavities, etc.). Door clearance, etc.) penetrates and generates air noise. Many models are not very good sealing performance, in the past is used in some parts of the body after some time, such as doors, trunk sealant aging, so that air noise is particularly evident. Applying automotive seals can solve the above problem. The sealing strip mainly applies the "glue-glue" principle to alleviate the problem of displacement gap between the door sealing edge and the metal edge of the door frame caused by the vibration of the vehicle body, fills the gap, and closely combines the door and the rear cover with the body, which greatly enhances the car's gas. The tightness can reduce the air noise more effectively into the interior of the car, as well as blocking the dust and heat. Resonance noise is formed by the reflection of noise in the room and the car's siding. Resonance noise is dominated by sound-absorbing products. Qualified sound-absorbing products have open and closed sound-absorbing chambers, which can effectively absorb and dissipate sound energy and convert sound waves into heat energy. Through the application of sound-absorbing materials, the reverberation noise in an automobile room is effectively absorbed and the resonance noise is eliminated, thereby effectively reducing noise.
