[China Glass Net] Automotive sealant strip is one of the important parts of automobiles. It is widely used in doors, windows, body, seats, sunroofs, engine compartments and trunks. It can be used to install passenger luggage compartment doors. The rubber hinge also has other functions such as waterproofing and sealing.
Daily maintenance and use tips for automotive sealant strips:
1. Check the seals for large cracks and cracks. If the seal is broken, it can be repaired with an adhesive. In particular, it is easy to fill a large crack strip by using a special adhesive for the seal. Of course, if the seal is seriously damaged, or the degree of aging is large, it is better to replace the new seal to save trouble.
2. After the car owner uses the car detergent to clean the door and window sealing strip, it is better to apply a layer of high permeability protective agent, which can prevent the sealing strip from aging and greatly improve the sealing of the sealing strip. In addition to this, the gap between the seal strips is easily filled with dust and rust. To this end, the dust should be removed with a brush.
3. When replacing the whole body, a layer of sealant should be applied on the overlapping part of the weld. The thickness of the glue layer should be about 1mm, and the glue layer should not have defects such as false stickiness and air bubbles. The entire lower surface of the floor and the lower surface of the front wheel cover should be coated with an elastic coating of 3mm-4mm and an anti-corrosion coating. These measures not only greatly enhance the sealing performance of the vehicle and slow down the rust rate of the vehicle body, but also greatly improve the ride comfort.
4. The sealing of the door and the body is a difficult part. The sealing requirements are strict. The part to be sealed is relatively long, the sectional shape of each sealing part is not the same, and the door is opened and closed frequently. In the limousine, three lanes, four seals are installed, and the four-seal structure of the front pillar and the roof side beam is installed. This multi-channel seal is generally arranged in the front door seam, in addition to the sealing function, there is also the effect of car noise reduction.
5. After the window glass is damaged, the owner should check the seal for damage when changing the glass. Since the window often fails to return to its original shape after repair, it is necessary to pay attention to the sealing 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 slot is not uniform, the rubber strip is in poor contact with the glass and the glass groove, and the owner can easily pull the seal off by hand.
6. When changing the roof of the car, the owner should first apply a layer of conductive sealant at the press-fit around the roof. After welding, apply the folded edge glue in the flow tank and the joint. This will not only help the body. The seal prevents the car from causing early corrosion due to water accumulation at the flange weld.
7. The car sunroof is the basic configuration of most family cars. When the sunroof of the car is opened, the rubber seal rail 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 block the drain hole. Therefore, it is important to clean the track regularly and apply lubricant to the track.
Although the car sealant strip is a small part in the body, it can ensure that the switch door is stable and heavy, and can also protect the car from wind and rain, dust, heat and sound, and decorate the edge of the door and window. When the body is vibrated and twisted, the sealing strip also acts as a buffer, shock absorber and protects the glass. Therefore, car maintenance is no small matter, and no link can be ignored.
