0 1 The internal and external protection of automobile interior is particularly important. Otherwise, the solvent used to clean the glass will pollute the interior and penetrate into the electronic control system of the automobile, leading to switch failure or even local short circuit. Therefore, care must be taken to protect the exposed electronic control switches and speakers of the vehicle. Specifically, cover the dashboard, door trim and back cover with protective film or thick bath towel, and properly protect the seat and steering wheel in the car. In addition, the exterior of the car body also needs proper protection to avoid scratching the paint surface. Rough cutting film first measures the size of glass. The film size at the top of the side doors and windows should be 5cm larger than the edge size of the original window glass, and the left and right sides should be larger than the edge size of the original automobile glass 1cm. At the bottom, leave a margin of 1~2cm when cutting the film. Note: when determining that the side door window glass is to be shaped and baked, vertical cutting must be selected. Clean the side glass sealing strip. There are two kinds of window glass sealing strips: rubber edge and raw edge. There are two cleaning methods for rubber edges: blowing away the sand and sundries hidden in the sealed tank with a blowing gun, or spraying an appropriate amount of water into the sealed tank, and directly cleaning the inner tank with a straight handle plastic scraper. Note that the scraper should be coated with a layer of waxing paper, and it should be rubbed in one direction, not back and forth, so as to avoid sand dust sticking to the waxing paper and being brought back to the groove. Two ways to clean burrs are to stick the inner felt wool on the edge of the sealing groove with 2cm wide textured paper, or to adjust the nozzle of the watering can to the minimum water output and spray a small amount of water on the felt wool to make it slightly wet and stick to the hair. The cleaning of the outside of the side glass is to spray the cleaning liquid on the outside glass and rub it by hand, because the hand has the strongest sensitivity and can feel slightly larger dust particles. The dirt with strong adhesion can be removed with a steel scraper, and other parts can be cleaned with wax paper. 04 Setting and Finishing Except for a few models, the side window film basically does not need to be heated for setting, and can be directly coated outside the glass for setting. Spread the window film on the outer surface of the glass with the protective film facing outwards. Note that the edge of the window film should be parallel to the outer bead, ensuring a sufficient margin (3~6mm) lower than the inner bead. Put on a brand-new blade, insert the head of the blade into a corner of the window film, lean the top of the blade against the ready-made frame, and cut with the window frame or adhesive tape as the guide. After cutting, slide the film to a proper position, squeeze and scrape the window film several times with a hard sheet squeezing tool to fix the whole film, carefully lift the film from the bottom, then lower the window glass to expose the top of the window glass, and cut the top edge with the edge of the glass. After the window is completely trimmed, transfer it to the cutting board for final trimming. Cleaning the inside of the glass is the real film surface, so it must be thoroughly cleaned and must be cleaned repeatedly according to the following requirements. First, spray water mist on the inner space of the carriage to make the dust in the air sink and reduce the dust on the seat and floor; Spray that cleaning liquid on the glass,
