What are the classifications of automotive sealing strips? How to maintain it on a daily basis?

The car leaves the factory with some seals installed. The function of the sealing strip is to fill the gap between the various parts of the body, so it will have the functions of sound insulation, waterproofing and shock absorption. But some car owners choose to install some seals to improve comfort, so what are the disadvantages of installing seals on the car?

1.Automotive weatherstrips are typically installed between the door and the underside of the door, the front cover, the trunk and the B-pillar. Because of the addition of the sealing strip, it is very likely that the door, trunk and other parts cannot be closed normally, and even the sealing strip will be exposed after closing, which is very impressive.

2.Installing a seal does not improve noise reduction. Because the sound insulation of a vehicle depends on many factors, it is obviously not practical to install only a seal.

3.The sealing strip is made of rubber and requires regular maintenance. If the sealing strip is aged, it is likely to fall off, affecting the appearance.

1.Silica gel. This type of adhesive strip has good air permeability, outstanding insulation, and is non-toxic, so it can be used in the car to reassure the owner.

2.Thermoplastic elastomers. These strips are elastic and abrasion-resistant, so they adapt well to both stretching and compression.

3.Thermoplastic vulcanizates. It has the advantage of being wasted** and then reused, and the material is also widely used in construction.

Do frequent check-ups. Check whether there is any obvious gap between the sealing strips and whether there are any breaks. If a slight break is found, one is repaired with a paste in time, and if the break is already noticeable, then it is better to replace it.

1. Vulcanized rubber sealant strip is a non-polar saturated backbone molecular structure polymer material, which has very good high temperature resistance, aging resistance, ozone resistance and ultraviolet resistance, and its molecular structure contains polar acetate side groups, outstanding chemical resistance, oil resistance and chemical resistance are very good. Its temperature range is -60 +150. Relying on excellent design and excellent comprehensive performance, it has been recognized by many customers, and at the same time, it actively develops new materials according to the needs of different customers.

There are door frame seals, sponge seals, rubber seals, and you can wipe them with wet wipes during daily maintenance, and a lot of water will make it melt and not sticky, so it can't stick.

No car! That's it! said that there was no car.

<> "Daily Maintenance of Automobile Sealing Strips.

Inspect the door and window seals for large cracks or breaks. If a broken seal is found, it can be repaired with a special adhesive for the seal. With this special adhesive, large cracks can be easily repaired.

Of course, if the seal is badly damaged or has a high degree of aging, it is better to replace it with a new one, which is more convenient.

After using car detergent to clean the door and window sealant strips, it is best to apply a layer of highly permeable protective agent. This prevents the weatherstrip from aging and greatly improves the sealing performance of the seal. In addition, the gaps in the finger strips of the sealing pin can easily be filled with sand and dust, which can lead to rust.

Therefore, sand and dust should be removed with a brush.

When replacing the entire car body, a layer of sealant should be applied to the lap of the weld. The thickness of the adhesive layer should be about 1mm, and there should be no defects such as false stickiness and bubbles. The lower surface of the floor and the lower surface of the front wheel cover should be coated with an elastic coating of 3mm to 4mm and an anti-corrosion coating.

These measures can not only greatly enhance the sealing performance of the whole vehicle and slow down the corrosion rate of the body, but also significantly improve the ride comfort.

The sealing of the door and the body is a more difficult part, the demand for sealing performance is higher, the part that needs to be sealed is longer, and the cross-sectional shape of each sealing part is different, and the door is also frequently opened and closed. Luxury sedans are usually equipped with 3 or 4 seals, as well as quadruple seals on the front strut and roof side beams. These multi-pass seals are generally arranged in the front door crack, and in addition to the sealing function, they also have the effect of sound insulation and lead noise reduction.

After the window glass is damaged, the owner should check whether the sealing strip is damaged when replacing the glass. Since the windows often do not return to their original shape after repair, it is necessary to pay attention to the tightness around the window glass in addition to ensuring that the window glass can be easily pulled or lifted. If the gap between the glass and the glass notch is uneven, and the rubber strip is in poor contact with the glass and the glass groove, the owner can easily pull off the sealing strip by hand.

When changing the roof, the owner should first apply a layer of conductive sealant at the pressing place around the roof, and then apply the hemming glue in the flow tank and the joints after welding, which not only helps to seal the body, but also prevents the body from early rust due to water accumulation at the flanging weld.

A car sunroof is the basic configuration of most family cars. When the sunroof is opened, the rubber sealing track is exposed to the air, which inevitably accumulates dust and even runs into small gravel. Prolonged use may cause the sunroof to deform due to wear and tear and clog the drain holes.

Therefore, it is important to clean the tracks regularly and apply lubricating oil to the tracks.

Although the car sealing strip is a small part in the body, it can ensure that the door is stable and heavy, and can also make the car shelter from weather, dust, heat and sound, and play a decorative effect on the edge of the door and window handover. When the body is vibrated and twisted, the sealing strip also plays the role of cushioning, shock absorption and protective glass. Therefore, car maintenance is no trivial matter, and no link can be ignored.

The daily maintenance of rubber sealing strips mainly includes the following contents: 1. When cleaning the stool with car cleaner, apply a layer of high penetration protective agent after cleaning to prevent the aging of rubber sealing strips. In addition, the gaps between rubber seals can easily fill with sand and dust, which can easily lead to rust.

Therefore, this problem cannot be ignored in the daily maintenance of rubber seals. You can use a brush to clean the sand and dust between the crevices. You can also usually use some protective agents before it rains.

In the case of sunroof vehicles, the sealing of the window glass and the body depends entirely on the sealing strip. If the seals are deteriorating and deformed, the cockpit may leak. Therefore, in case of rainy weather, apply a layer of adhesive strip protector in advance.

If it can be maintained regularly, the sealing performance of the sealing strip can be greatly improved. In addition, the owner inspects the rubber seal at the door for large cracks and breaks. If the rubber sealing strip is broken or has small cracks, it can be repaired with adhesive glue.

In particular, the special adhesive sealing strip makes it easy to repair cracks in rubber sealing strips. Of course, if the rubber seal is badly damaged or aged, it is recommended that you replace it.
