Wash the car, clean the inside and outside of the car, and film it in a clean and dust-free place. Step 2: Measure the window size and cut the film according to the size. The size must be right. If you are not sure, the size can be slightly larger, but it must not be small. Step 3: Clean the window glass. This step is very important, because if there is dirt on the glass, even a little bit will affect the quality of the film. Prepare two scrapers in advance, a hard scraper and a soft scraper. When spraying water on the glass, first scrape off the obvious dirt on the glass with a hard scraper, and then scrape off the water mark on the glass with a soft scraper. Repeat this three or four times until the water is completely removed. Finally, spray water on the thoroughly cleaned glass window and close the window, leaving only the person sticking the film in the car. Step 4: Paste the film. Tear the film, spray water evenly on the effective film surface, and put the torn plastic film aside for use. Leave a distance of 5- 10mm above the glass, and stick the membrane surface on the car glass and fix it. Don't spray water at this time, and fix the film with tape. If the film is cut slightly larger, it is necessary to cut off the excess film without scratching the glass, and then scrape it flat with a soft scraper. In order not to scratch the film surface, spray water on the pasted film surface, stick the torn plastic film on it, scrape the film flat with a scraper, and finally tear off the plastic film, thus completing the whole film pasting process. Step 5: Wipe off the water mark left in the corner of the window with suede. In addition, the quality of membrane directly affects the construction quality. Even if the anhydrous baking membrane technology is adopted, the poor quality of the membrane will cause problems. The headquarters of Chinipu Beauty Maintenance Chain adopts the high-quality explosion-proof solar film produced by American advanced technology, which has good performance in heat resistance, ultraviolet protection, ultra-perspective, explosion protection, wear resistance and environmental protection, and is in the leading position in the same industry in quality, which can meet the needs of customers to the greatest extent. Compared with the original film baked with water, the film baked without water has many advantages, 1, and the speed is faster. Because there is no need to spray water on the car glass, the baking process is greatly shortened, which is especially important for modern people whose time is the concept of money. 2. Prevent the car glass from bursting. Because the film baked with water is sprayed on the automobile glass, when it is baked with a blower, the cold and hot meet, which is easy to crack the automobile glass, while the film baked without water completely avoids this situation. 3, wrinkles are not easy to appear. Baking the film with water increases the dispersion point of the film and leads to wrinkles. The baked film has few scattered points, which avoids the appearance of wrinkles. Moreover, after spraying water, water droplets are easily contaminated with dust, which makes the windows blurred. 4. The adhesive layer of the film layer will not be damaged. The reason why the window film can prevent sunlight is that it has a heat insulation layer and an ultraviolet-proof metal layer, but the water spraying baking film is easy to damage the metal layer and the heat insulation layer and reduce the heat insulation rate. In addition, due to the damage of the metal layer, the car film cannot be refracted. When two cars meet at night, the other car lights often make you unable to see clearly, which is easy to cause a car accident. Another factor that is easy to cause traffic accidents is that after water spraying baking, it is easy to make the surface of the film uneven and "orange peel" appears, which makes the driver feel dizzy while driving and increases the accident rate of the driver to some extent. Baked film has no water and no worries.
