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 the 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 entire 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 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 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 slot is uneven, and the rubber strip is in poor contact with the glass or glass slot, the owner can easily pull the sealing strip off by hand.
6. When the owner of the car changes the roof, he should first apply a layer of conductive sealant at the pressure joint 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 auto sunroof is open, the rubber seal track is exposed to the air and it is difficult to avoid accumulation of dust 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 inside the body, it can ensure that the door of the switch is heavy and heavy, and it can also make the car weatherproof, dustproof, heat-insulating and soundproof, and it can decorate the edge of the door and window. 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.

Carbon
The carbon and graphite materials are non-metallic solid materials dominated by carbon, wherein the carbon materials are substantially composed of non-graphitic carbon, and the graphite materials are substantially composed of graphitic carbon. Not only graphite, but also all diamonds, fullerenes, and carbenes are called carbon materials.
Property: Lightweight, porous, conductive, thermal conductivity, corrosion resistance, lubricity, high temperature strength, heat resistance, thermal shock resistance, low thermal expansion, low elasticity, high purity, processability.
Classification: Carbon products can be classified into graphite electrodes, carbon blocks, graphite anodes, and carbon according to product applications.
Carbon materials Electrodes, pastes, electrocarbons, carbon fibers, specialty graphites, graphite heat exchangers, etc. Graphite electrode type can be divided into ordinary power graphite electrodes according to the allowable current density. High power electrode, ultra high power electrode. Carbon blocks can be divided into blast furnace carbon blocks, aluminum carbon blocks, and electric furnace blocks according to their purposes. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers, and special graphite products, depending on the raw materials and production processes. Carbon products can be classified into ash products and ash products (having ash content less than l%) according to the ash content.
The upstream enterprises in the carbon industry mainly include: 1. Calcined enterprises of anthracite; 2. Coal tar processing and production enterprises; 3. Petroleum coke production and calcining enterprises.
