Automotive silicone sealing ring is one of the important parts of automobiles. It is widely used in the fields of doors, windows, body, seats, sunroofs, mobile chassis, luggage, etc. It is waterproof, sealed, soundproof, dustproof, antifreeze and shockproof. , heating, energy saving, etc. play an important role, automotive silicone sealing ring is mainly composed of EPDM rubber (ethylene propylene diene monomer), has good elasticity and resistance to compression deformation, aging resistance, ozone, chemical action, operation Wide temperature range (-40°C~+120°C), unique metal fixture and tongue buckle for durability and easy installation.
As we all know, automotive silicone seals seal due to their colloidal properties. It is not difficult to find seals on the edges of doors, windows and skylights. These less conspicuous seals are often a problem that owners ignore when car maintenance.
If the automotive silicone seal is exposed to the sun for a long time, it is easy to age and crack, and the sealing performance will be greatly reduced, which will not only affect the sound insulation effect of the automobile environment, but also affect the leakage and leakage. To do a good job of repairing the seal, the owner must start with the daily chores. In order to clean the car's silicone seals, the owner can clean the seals once every two or two quarters. Specifically, you can wipe the dust on the rails and grooves with a clean, damp sponge and then wipe it again with a dry sponge to keep the car's silicone seal clean. These operations are very simple, if you go to a professional car beauty shop to wash the car, the professional operation will have a better effect.
If you use a high-pressure water gun when washing a car, remember not to spray water directly on the car's silicone seal ring. Otherwise, it is easy to deform the car's silicone seal ring under the impact of the high-pressure water column, which will affect the sealing performance of the seal ring for a long time. Cars are easier to get into the water. In addition, the owner should also pay attention to the parking lot. When it is necessary to park outdoors for a long time, the vehicle should try to avoid direct exposure to the sun. If possible, it is best to cover some special reflective car clothing to prevent the door and sunroof seal from deforming and cracking due to heating.
If this is unavoidable and does not use direct water splashing for physical cooling, then large temperature differences tend to change the internal structure of the automotive silicone seal, causing it to deform and crack.
