When repairing the automobile line, all the body holes and holes should be installed in place, because these sealing rings not only play a sealing role, but also play a role in protecting the wiring harness. If the sealing ring has been damaged or the wire harness can rotate or move in the sealing ring, the sealing ring should be replaced, and it should be firmly assembled with the body holes and holes, and the wire harness will be stable.
After the window glass is damaged, the glass with the same curvature as the original window glass should be replaced, and the glass guide groove and sealing strip should be checked for damage. Because the window after repair is often less than the original shape, therefore, at this time in addition to ensure that you can easily pull or lift car window glass, but also pay attention to the sealing around the window glass after the window is closed.
When repairing doors with sealing flanges, attention should be paid to repairing damaged sealing flanges and accurately restoring the shape of the original flange. After repairing the door to carry out sealing inspection, inspection method is: put a piece of cardboard on the sealing position, close the door, and then pull the paper, according to the size of the tension to judge whether the seal is good. If the force required to pull the paper is too large, the seal is too tight, which will affect the normal closure of the door, and will also make the seal due to deformation of too large surface faster loss of sealing performance; If the force required to pull the paper is too small, it shows that the seal is not good, and often the door does not block the wind and rain. In the replacement of the door must pay attention to the new door in the inside and outside plate flanging occlusion of the coated folding glue, and some of the small holes left in the stamping process with this base tape.
When replacing the roof, a layer of conductive sealant should be coated at the pressing place around the roof first. After being welded, the folding glue is coated in the flow flume and the joints. This not only helps the sealing of the body, but also prevents the body from early corrosion due to the water at the flanging weld. When assembling the door, a whole piece of sealing isolating film should be pasted on the inside plate of the door below the window. If there is no forming sealing isolating film, ordinary plastic paper can be used to replace it, and then the sealing isolating film is pasted and compacted, and finally the interior trim panel is assembled.
In the replacement of the whole body, in addition to the completion of the above projects, should also be in the lap part of the weld and solder joint are coated with a layer of sealant, the thickness of the adhesive layer should be about 1mm, and the adhesive layer shall not have virtual adhesion, bubbles and other defects; In the folding place should be coated with special folding glue; 3mm-4mm elastic coating and anticorrosive coating shall be applied on the entire lower surface of the floor and the lower surface of the front wheel cover; Before the surface on the floor and the surface inside the upright board should stick up film of sound insulation, heat insulation, reduce vibration and damping, spread heat insulation felt block next, carpet or decorate floor on respread finally. These measures can not only greatly enhance the sealing of the whole vehicle and slow down the corrosion speed of the body, but also greatly improve the ride comfort.
