Sealing tape daily maintenance tips
Frame steel electric scooters are generally more compact and stylish appearance, generally less than one meter easy to carry. Electric scooters can be folded, fold up small footprint can easily carry. For office workers, you can go out to ride the Electric Scooter to the bus station by car, and then when the bus can be folded to carry, work when the trunk can be put elevator. Electric scooters do not need people to rely on the strength of the waist twisting and foot push to promote skateboarding, but the use of electricity as energy, battery capacity. Electric scooter battery in addition to large capacity, there are high-power motor, scooter can ensure long life, with strong power and climbing ability. High strength steel frame, light weight, large span.

1. Check if the seal has large cracks and breaks. If the seal breaks, it can be repaired with an adhesive. In particular, it is easy to repair large cracks by using adhesives for sealing tapes. Of course, if the sealing strip is seriously damaged or has a relatively large degree of aging, it is better to replace it with a new one.
2. After the car owner uses car detergent to clean the door and window sealant, it is better to apply a layer of high-permeability protective agent, which can not only prevent the aging of the sealer but also greatly improve the sealability of the sealer. 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.
3, in the replacement of the whole body, should be a layer of sealant in the overlap of the weld seam, the thickness of the adhesive layer should be about 1mm, and the adhesive layer shall not have defects such as viscous, air bubbles. 3mm-4mm elastic coating and anti-corrosion coating should be applied on the entire under floor surface and under the front wheel cover. These measures can not only greatly enhance the overall vehicle's tightness and reduce the rust speed of the body, but also can greatly improve ride comfort.
4. The seal between the door and the car body is a difficult part. The seal requirement is strict, the part that should be sealed is relatively long, the cross-sectional shape of each seal part is not the same, and the door is frequently opened and closed. In the limousine, three lanes, four lanes of seals, and a quadruple-seal construction with the front pillars and the roof side cross-members are installed. This kind of multi-channel seal is generally arranged in the front door joint, in addition to the sealing function, there is the role of car noise insulation.
5. After the window glass is damaged, the owner should check the seal for damage when changing the glass. Since the windows are often not restored to their original shape after repair, it is also necessary to ensure that the window glass can be sealed tightly in addition to easily pulling or lifting the window glass. If the gap between the glass and the glass notch is uneven, and the rubber strip is in poor contact with the glass or glass, the owner can easily pull the seal off with his/her hand.
6. When the car owner changes the roof, he should first apply a layer of conductive sealant at the press-bonding area of ​​the roof, and then apply the folded edge glue in the flow sink and seams after welding. This will not only help the car body. The seal can also prevent the car body 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 is opened, the rubber seal track is exposed to the air, so it is hard to avoid dust accumulation and even run into small gravel. Prolonged use may cause the skylight to deform due to wear and block the drain hole. Therefore, it is very important to apply the lubricant to the track regularly to clean the track. Although the car sealant is a small part in the car body, it can ensure that the door of the switch is steady and heavy, and it can also make the car weatherproof, dustproof, heat-insulating and sound-insulating and play a decorative effect on the edge of the door-window transfer. When the body is subject to vibration and distortion, the sealing strip also acts as a buffer, absorbs shock, and protects the glass. Therefore, car maintenance is not a trivial matter, and any link can not be ignored.
