How to extend the service life of waterproof casing?

Generally speaking, in order to prolong the service life of waterproof casing, it is necessary to paint anti-corrosion treatment in case of no special requirements. It is not only beautiful, but also has a longer service life.
 
The importance of the coating is that the manufacturer, after making the waterproof casing, will spray corrosive coating as a whole in order to facilitate the user's application on site and not to install the wrong one, spraying evenly on the inner and outer walls, and then spraying the model number on the casing. Therefore, the corrosion of the pipe is related to the service life of the waterproof casing, painting anti-corrosion treatment is very important.
 
In addition, the bursting sun is very harmful to the waterproof casing. Therefore, in the application process, it is strictly forbidden to expose the uninstalled flexible waterproof casing to high temperature and strong light for a long time, you can cover the unused waterproof casing with sunshade cloth, because high temperature and strong light is very harmful to the seal, long exposure will make the rubber seal aging deformation, lose no elasticity, the squeeze of the gland flange in use can not make it deformed, resulting in poor sealing, water leakage and other phenomena.
