Sealant strip is one of the important parts of the automatic mixer. It is widely used in doors, windows, car bodies, seats, skylights, engine cases, trunk and other parts. It can be used to produce rubber hinges for the installation of luggage compartment doors of passenger cars, as well as other waterproof and sealing functions.
1. Check the sealing strip for large cracks and fractures. If the sealing strip breaks, it can be repaired with adhesive. Especially with the special adhesive for sealing strip, it is easy to repair the large crack strip. Of course, if the seal is seriously damaged or aging, it is better to replace the new seal easily.
2. After using detergent to clean the sealing strip of doors and windows, it is better to apply a layer of high permeability protective agent, which can not only prevent the sealing strip from aging, but also greatly improve the sealing performance of the sealing strip. In addition, the gap between the sealing strips is easy to be filled with sand dust, thus causing corrosion. Therefore, the dust should be removed with a brush.
3. When replacing the whole body, a layer of sealant shall be applied to the overlap part of the weld seam, the thickness of the adhesive layer shall be about 1mm, and the adhesive layer shall be free of defects such as virtual adhesion and bubbles. 3mm-4mm elastic coating and anti-corrosion coating shall be applied to the whole lower surface of the floor and the lower surface of the front wheel housing. These measures can not only greatly enhance the sealing performance of the whole vehicle and slow down the corrosion speed of the 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 relatively strict. The parts that should be sealed are relatively long. The cross-section shape of each sealing part is different, and the door is opened and closed frequently. In the high-end car, three or four seals are usually set, and the four seal structure of front pillar and roof side crossbeam is installed. This kind of multi-channel seal is generally arranged in the front door seam. In addition to the sealing function, it also has the function of automobile sound insulation and noise reduction.
5. After the window glass is damaged, the owner should check whether the sealing strip is damaged when replacing the glass. As the window often fails to return to its original shape after repair, at this time, in addition to ensuring that the window can be easily pulled or lifted, attention should be paid to the sealing around the window. If the gap between the glass and the glass slot is uneven, and the rubber strip is in poor contact with the glass and the glass slot, the owner can easily pull the sealing strip off by hand.
Although the sealant strip is a small part in the car body, it can ensure the door to be opened and closed stably and massively, and it can also make the car avoid wind and rain, dust, heat insulation and sound insulation, playing a decorative effect on the edge of the door and window joint. When the body is subject to vibration and distortion, the sealing strip also plays the role of buffer, shock absorption and glass protection. Therefore, there is no small matter in the maintenance, any link can not be ignored
