Car sealing strips have the function of filling various gaps between various parts of the vehicle body, and have functions such as shock absorption, waterproofing, dust prevention, sound insulation, decoration, etc. Improve the comfort of the driving experience and protect the vehicle body.
Generally, if a car owner experiences driving in a certain state, such as on highways, sandy roads, or in busy urban areas, and feels strong noise, it is more likely that there is a problem with the sealing performance of the vehicle body. There are many ways to solve problems, and sealing strips are one of the cost-effective solutions. Car sealing strips are usually configured at the factory, and rubber strips with varying quality will age prematurely, leading to a decrease in sealing performance and disappearing after a period of use. Car sealing strips are very useful products for solving noise problems.
As is well known, the function of car sealing strips is not only to prevent objects from entering the car, but also to effectively prevent rainwater from splashing into the car, allowing car owners to drive normally. In addition, the sealing strip can also reduce the wind noise from the outside when the car owner is driving, and has the function of shock absorption and dust prevention.
What are the characteristics of car sealing strips? Let's take a brief look together.
In the low-temperature test at -40 ℃, the sealing tape did not harden or become brittle, but still maintained its softness and good adhesion, demonstrating excellent cold resistance. But at a high temperature of 120, the weather resistance of the sealing strip is still good, the elasticity is maintained, and the shape and function are not affected.
The selection of sealing material determines its permanent softness and elasticity. By adjusting the formula, the softness of the dried sealant can be improved, thereby forming a good sealing layer between the sheet metal and the adhesive strip. The unique high elasticity of Butyl rubber ensures that the sealant can be easily stripped from the metal plate without polluting the metal plate.
The automobile sealing strip is mainly made of EPDM rubber with good elasticity, compression deformation resistance, aging resistance, ozone resistance and chemical action resistance, and a wide temperature range (-40 ℃~120 ℃). It is foamed and compact. It contains a unique metal clip and tongue shaped buckle, which is durable and easy to install.
What are the precautions for replacing car sealing strips? Let's take a brief look together.
Before replacing the sealing strip, it is necessary to choose a suitable sealing strip style based on your vehicle model. Generally speaking, different sealing strips are equipped with different vehicle models.
After selecting the sealing strip, remove the old sealing strip, wipe the surrounding area of the sealing strip, apply protective agent, and then install it.
When replacing the sealing strip, there will be one or two water outlets left on the door. Attention: Do not block these drainage holes to avoid water accumulation in the car.
