When a car arrives, the receptionist will check the whole car to see if it is damaged and if the property in it is properly registered.

Installation standard: the width is from the midpoint of the straight line at both ends of the top to the midpoint below. extremitas inferior

The length of two straight lines is the length. Determination of the highest point of the upper end: fix it on the two corners of the upper end of the glass with wires,

If the midpoint of the line is in the glass, the highest point of the glass is the highest point. If the midpoint of the line is outside the glass, then

Take the midpoint of a straight line as the highest point. The method to determine the lowest point of the lower end is blanking:

Select the model of the film, mark the length of the big end at the bottom on the original car glass in large quantities, measure the width of the glass (length 5- 10cm) from the middle, and pay attention to the directionality of the film, so that the length of the glass corresponds to the side length of the film and the width corresponds to the width direction of the film for film cutting. The long side of the membrane is contractile, but the wide side is not.

Vertical blanking, rectangle.

This method is characterized by standardization, time saving, material saving and easy pasting. Cleaning the outside of the glass:

Clean the outside of the glass by hard scraping and soft scraping, and finally check that there is no dust and water on the glass and no dust on the side seams.

Spray water on the glass, cover the glass with lining paper, keep it parallel to the glass, and then fix it with a hard scraper before baking the film;

After cutting the window film size, any bending on the glass will be obvious, and almost all the front and rear windows have slight spherical bending, which makes the window film unable to be laid on the glass. Using portable hot air gun, the window film can be accurately shrunk on the composite surface of most windows to remove the wrinkles on the curved surface.

Hot gun setting method is carried out before mounting and pasting, which can not only save a lot of folding time, but also make the appearance of window film more comfortable and beautiful.

Bite open the corners of the cut front bumper film with your teeth to distinguish the surface of the film. Spread the protective film face up evenly on the glass, and cut off the excess part (subject to the black edge of the glass). The upper and lower sides of the membrane are evenly separated from the middle, and the two wide-sided bubbles are evenly separated from the upper and lower sides together. Scrape the water in the middle part with a scraper, and be careful not to scratch bubbles to prevent scratching the film. The function of wiping the middle part first is to shape the solar film so that it will not move, and the bubbles in the film will be evenly separated to the two long sides, which is beneficial to baking the film. Molding:

It is divided into dry baking and wet baking.

Glass with large radian often adopts a combination of the two, which is dry baked first and then wet baked. The advantage of dry baking is that you can stick a large film on the glass and bake it smoothly with bubbles. The striped glass in the back is baked like the glass without stripes. Trim (vertical 90 degrees), a certain standard.

Baked film

Divide bubbles into equal parts of similar size. From top to bottom, from middle to side, from easy to difficult, bake small bubbles first. After baking the small bubbles, separate the big bubbles and bake them again. When drying film, pay attention to the temperature of the drying gun and the heating degree of the film. The temperature can be adjusted by distance.

When baking bubbles, the bubbles should be heated evenly, and the baking gun can be properly held at the edge of the film for 1-2 seconds, so that the edge of the film will shrink and will not be uneven all the time.

Pay attention to the shrinkage of the film when baking. When the film crinkles and shrinks, scrape it to the bottom with a scraper. If the bubbles are too big, you can smooth the film by hand and scrape it clean with a scraper.

When baking the film, don't stay on the bubble for too long, so as not to get too hot. If the temperature is too high, the film will be scorched, and the glass will be broken. At this time, you can't spray water on the car glass, because you can't stand the stimulation and the glass explodes. Finishing:

After baking a piece of film, cut off the extra edges. The front windshield has a rearview mirror. If you want to scrape the hole, you only need to scrape it 2mm away from the black edge to make it opaque.

Glass trimming requirements: straight, flat and even. Cleaning:

Wipe the dashboard flat with a big towel to prevent water leakage, and close the door to clean the glass. When cleaning the glass with stripes on the back, follow the direction of the stripes, otherwise dust will easily accumulate on both sides of the stripes, and many small bubbles will be formed when sticking the film. Add two or three drops of finger-sized flexible cleaner (mainly used for cleaning and lubrication) to the watering can. Spray a proper amount of cleaning agent water on the outside of the glass to be pasted, carefully scrape off the whole glass with a steel scraper or a plastic scraper to remove the dirt stuck on the glass, and then wipe the glass with a special wiper for the front and rear blocks after spraying water.

After cutting and any necessary thermoforming, the inner surface of the glass must be cleaned with a strong liquid cleaner. Use a small watering can filled with window film installation liquid or any high-quality window glass cleaner and appliance suitable for this purpose. Most surfaces can be scraped off with a shovel, and nylon soft lotion can be used. Be especially careful when cleaning the rear window glass (especially those colored decorative points of nonferrous metals and edges). Finally, the window glass is scraped clean, and the frame is wiped clean with soft cloth and scrubbing paper to restore the clean state of the glass surface and prepare to install colored or metallized films. If the film is baked on unclean glass, when the film becomes soft after heating, the dirt or sand on the glass will leave traces on the film after the film is scraped off by a scraper. These marks can not be removed even after pasting, thus affecting the quality, beauty and clarity of pasting.

Clean glass

A. If the glass is labeled, it can be cleaned with asphalt water;

B, carefully scrape the glass with a steel scraper (including the upper edge and lower edge of the corner);

C, scrape water with a rub scraper or a steel scraper;

D, clean the glass for the last time before sticking the film, and do not leave water droplets on the glass;

E. Before tearing the film, spray water in the car or spray some water on the film to eliminate static electricity. Squeeze water:

Two people finished eating in the car. When driving away water, especially the striped glass should follow the striped direction and then scrape up and down, which can drive away 90% of the water. This can prevent wet air from being inhaled and bring dust into the film.

After each window film is fixed in its final position, the installation liquid is sprayed on the surface of the window film again to lubricate the pressed surface. Use a special water squeezing tool to remove all bubbles and as much installation fluid as possible. After a few days, the accumulated water will be slowly discharged through the window film. The drying time of window film depends on climate, humidity, structure of window film and water quantity after extrusion. Check:

If there are bubbles around, you can scrape the steel and bake the flat film.

After the installation work is completed, all the windows are carefully cleaned (inside and outside surfaces) to remove striped water and stains, so that the appearance of the whole vehicle is beautiful.

Check the problem area: remove bubbles, blisters or tiny fibers along an edge. Special hard water extrusion can remove most problems.

Then, wash the car and drive it outdoors to achieve the final visual inspection.
