Vulcanizing a moped or scooter's camera is a more serious process than simply gluing a patch. Therefore, so that the wheel does not deflate at the most inopportune moment, it is worth following a simple vulcanization technology.
After the camera is removed from the wheel, it is necessary to determine the location of the damage; to do this, pump up the removed camera and visually find the puncture. If this cannot be done immediately, then you can immerse it in a suitable container; escaping air bubbles will indicate a defective area. In order not to lose the puncture site, stick a match into it. Conventionally, the vulcanization process can be divided into 2 types.
Cold way
You will need a special set for gluing patches, fine sandpaper, any degreasing liquid and a knurling (roller) to press down the glued patch. Place the camera on a flat, convenient place, pull out the match and determine the place of the future patch in order to select it from the set by size (the overlap of damage on all sides should be approximately 1.5 cm). Take a fine emery cloth and carefully work the area around the damage. Now degrease the whitened area with a solvent, wait until it dries, and apply a thin layer of glue.
While it dries (3-4 minutes), prepare the patch by removing a thin layer of protective film from it. Now apply the patch over the damaged area, being careful not to touch the puncture site with your hands, and press well, pressing on the center and edges. Finally, roll the patch with a suitable roller. Such repairs, carried out with high-quality materials, will allow the scooter to travel more than one thousand kilometers. However, there is also a more reliable repair method that allows you to successfully glue cameras not only for mopeds, but also for trucks.
Hot way
This is a more reliable method, requiring raw rubber and a vulcanizer, which can be electric or field (gasoline-powered). Raw rubber is similar to normal rubber, but softer and more pliable to the touch. Having identified the problem area on the camera, having cleaned and degreased it, take a suitable piece of crude rubber and immerse it in gasoline for 3-5 minutes. When the patch is swollen, place it over the puncture site and cover with paper so that the camera does not touch the sole of the vulcanizer.
Clamp the resulting "hamburger" in an already warmed-up device. The scooter tube curing time is approximately 5 minutes. More precisely, you can calculate using the formula, multiplying the thickness of the chamber in millimeters by the number 7. When the time is up, let the vulcanizer cool, then remove the paper and sprinkle the patch with talcum powder so that the tire does not stick to the chamber. It remains only to check the quality of vulcanization by pumping the chamber to an elastic state and lowering it into water. The absence of bubbles means that everything is done correctly.
