Second, add two or three drops of finger-sized flexible detergent (mainly used for cleaning and lubrication) to the glass jar and shake it with water. Spray an appropriate amount of water on the outside of the glass to be pasted, carefully clean the whole glass with a steel scraper or a plastic scraper to remove dirt on the glass, spray water on it, and then clean the glass again with a special wiper for the front and rear blocks. If the film is baked on unclean glass, when the film becomes soft after heating, scraping things on the glass with a scraper will leave traces on the film. These marks can't be removed even if the film is pasted, thus affecting the quality, beauty and clarity of the film.
Third, the plastic teeth before baking the film bite the corners of the film, thus distinguishing the side with protective film. Spread the protective film with one side facing up evenly on the glass, and cut off more parts (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 wiper, and be careful not to scratch bubbles to prevent scratching the film. The middle part is rubbed first for setting, so that the solar film will not move, and the bubbles of the film will be evenly separated on both sides, which is beneficial to baking the film.
Fourth, bake the film and divide the bubbles into equal parts of similar size. From easy to difficult, bake small bubbles first. After the small bubbles are baked, bake the big bubbles into small ones. Pay attention to the temperature of the drying gun and the heating degree of the film when drying the film. You can adjust the temperature by distance or speed. When baking bubbles, the bubbles should be heated evenly, and the baking gun can keep it for 1-2 minutes to make the film edge shrink and then flatten it. Pay attention to the shrinkage of the film when baking. When the film shrinks into wrinkles, 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, you can't stay on a bubble for too long to avoid being too hot. If the temperature is too high, the film will burn lightly and the glass will burst. This is not allowed to spray water on the car glass to prevent the glass from bursting because it can't stand the stimulation.
5. After trimming and baking a piece of film, cut off more edges. The front windshield has a rearview mirror, and 2mm from the black side is enough. Glass trimming requirements: straight, flat and even.
Method for avoid sand grains in film
1, water Many construction workers use tap water directly without filtration or precipitation, which is incorrect, because there are many impurities or sand grains in the tap water pipeline, and sometimes replacing the water pipe will affect the water quality. Therefore, the water used in the sticker must be filtered or precipitated.
2. Dust Many storefronts don't have special film pasting rooms. Cars the size of film whizzed by the roadside, causing a lot of dust, sometimes with high wind speed and dust. Therefore, when there is no film pasting room, all the doors should be closed before pasting.
3. A large amount of static electricity will be generated when the transparent part of the insulating paper is disassembled by the work clothes. If a sticker is attached, it is not suitable to wear wool or clothes with cotton wool, because the cotton wool or wool on the clothes will be attracted to the paper by static electricity.
4. Paper surface The paper we cut is often placed on the car mat, chair cover, or the roof and hood, resulting in unclean inside and outside. When the paper is disassembled, the dust attached to the surface will also be adsorbed on the paper due to static electricity. Therefore, when the transparent paper is not removed, it must be cleaned or sprayed with water to prevent dust and sand.
5, chair covers or objects are also static, some chair covers are too much rabbit hair, fox hair or cotton wool, you should also pay attention when unpacking paper, don't be too close to the object when unpacking paper, so as to avoid the dust on the object being electrostatically adsorbed.
6. When the paper was opened, someone opened the door. Don't let people outside the car open the door when washing the glass or opening the paper. Sometimes forcibly opening the door will lead to rapid air circulation and bring in a lot of dust or sand.
7. The air conditioning wind speed is too high. Summer is the peak season for insulating paper. Sunbathing or the temperature inside the car is very high, so it is inevitable to turn on the air conditioner in the car. However, when disassembling the paper, the air-conditioning wind speed should be adjusted to the minimum. After disassembling the paper and pasting the glass, increase the wind speed to avoid the dust flying around the car quickly.
8. The bottom of the sprinkler is not clean. When using sprinklers, most of them are placed on the ground, cushions or chair covers, and the bottom is often dirty. When you open the paper, if the nozzle shakes on the paper, the sand and pebbles at the bottom will fall on the paper. When we use the sprinkler, we wipe our bottoms first.
9. After disassembling the transparent paper by hand, you must hold down the insulating paper with two fingers. There will be fingerprints and sand grains on the pinched part. The trick is to control the paper pinch less.
10, wiper mode is incorrect. Wipers have a fixed way to clean the glass. If you wipe it casually or intermittently or don't know how to finish it, it will bring sand.
1 1. If the wiper next to or at the bottom of the washing water cannot reach completely, it must be washed. If cleaning with toilet paper, pay attention to using degreasing toilet paper to avoid dust. Old cars or triangular windows should be washed more carefully, but the top should not be washed, so as to avoid the stolen goods slipping with the water.
12. Pay attention to the objects in the car after removing the paper. When spraying water on the glass, be as accurate as possible. If you find that the position difference is a lot after pasting, you will touch objects around the glass or rubber and sand in the mud jar if you move again.
13. The next action is to catch water just after the direction of catching water is attached. Water can be pumped in from top to bottom, from right to left or from left to right, but a lot of water can't be pumped out from bottom to top, so as not to knock the sand down.
14, don't try not to lift the paper when it has been pasted with glass. The more times you lift it, the more dust particles there are.
15, glass cleaning is not clean. Some old cars were torn down and replaced with new ones. The attached ash should be scraped clean, and any labels and stolen goods should be cleaned up in time, otherwise no matter how good the technology is, it will not help.
16, the last action of the sticker is to push water. Generally, more than 80% technicians can't push out most of the water. When evaporation is slow in winter for a month and a half, we will clean the removed transparent paper, put glass on it and squeeze out the water with copper plates. This way not only won't scratch and scratch the paper, but also squeeze out the sand from big to small and from small to nothing.
17. The gas belt is pumped by sand into the mud trough around the old car, and there are many invisible sand and dust hidden in the rubber. After the paper is closed, some glasses have a large arc and the air belt will be triangular. At this time, if the water is not driven out quickly, sand will be pumped into the water continuously.
18. When cleaning the window, you should roll it down first and then wipe it on it. Don't wipe the glass on it after scraping the water.
