What is the construction method of seals?

[Summary description] Use cotton gauze to remove dust, oil and open water from the surface of the glued part of the seal. If there is easy peeling and rust on the surface, it should be removed with a metal brush in advance. If necessary, organic solvents such as alcohol and acetone can be used to wipe the surface. Cut the nozzle of the sealant into a certain shape according to the shape of the construction site, and use manual or pneumatic glue. Use a gun to apply glue to the construction site, and perform surface smoothing and modification within the drying time. Parts with particularly strict surface requirements should be covered with protective tape on both sides of the glued part and removed after scraping.
