. check whether there are large cracks or cracks in the sealing part of the feeding mixing integrated system. If the seal breaks, it can be repaired with adhesive. In particular, sealing with a special adhesive can easily fill large cracks. Of course, if the seal is seriously damaged or damaged, replace it with a new one.
2. After cleaning the sealing strip of doors and windows with concrete mixing cleaner, the driver shall apply a layer of anti-seepage protection agent to prevent the aging of the sealing strip and greatly improve the sealing performance of the sealing strip. In addition, the gap between the weatherstripping is easy to be filled with dust and rust. To do this, use a brush to remove the dust.
3. When replacing the whole body, a layer of sealant must be applied to the weld. The thickness of the adhesive layer shall be approximately 1 mm and the adhesive layer shall be free from defects such as false adhesion and air bubbles. The whole bottom surface of the floor and the bottom surface of the front wheel cover must be coated with 3mm-4mm elastomer coating and anti-corrosion coating. These measures not only greatly improve the sealing performance of the vehicle, but also slow down the body rust, and greatly improve the ride comfort.
4. Sealing doors and doors is a relatively difficult part. The sealing requirements are relatively strict. The sealing part is relatively long, the cross section shape of each sealing part is different, and the door is often opened and closed. The feeding and mixing machine is equipped with three-way and four-way seals, four sealing structures, front strut and side beam of roof beam. This multi-channel seal is usually placed at the joint of the front door. In addition to the sealing function, it can also reduce the noise of the car.
5. After the window glass breaks, the driver needs to check whether the sealing strip breaks when replacing the glass. Since the window cannot be restored to its original shape after maintenance, in addition to making the window glass easy to pull and lift, attention must also be paid to the sealing strip around the window glass. If the gap between the glass and the glass tank is uneven, the rubber strip has poor contact with the glass tank, and the driver can easily pull the sealing ring by hand.
6. When replacing the roof, the driver must first apply a layer of conductive sealant around the roof. After welding, the flow channel and joint shall be coated with curling adhesive. It's not just good for the body. The seal prevents premature corrosion of the vehicle due to water accumulation in the flange weld.
