Technical requirements for sticking car window film

Pasting automobile heat insulation film has now become one of the necessary equipment items of the car. In summer, a thin layer of heat insulation film can play a big role, not only can play an explosion-proof role, but also heat insulation and UV protection. Industry insiders pointed out that the heat insulation effect is one of the important reasons for consumers to choose the film, but the light transmittance and UV index of the heat insulation film are all consumers must care about.Front windshield transmittance is the most importantAutomotive insulation film has front and rear windshield film and side windshield film. Among them, the most demanding thermal insulation film is the front windshield. In addition, according to the regulations of the Ministry of Public Security's traffic safety regulations, the light transmittance of the front windshield must be greater than 70%. On the premise of not affecting the safety of driving, the front windshield is most taboo to stick a dark insulation film. In addition, when choosing the UV resistance index of the heat insulation film, the higher the better, because it can protect the center console components and prevent them from being aged in advance due to long-term sun exposure.Linshang LS122 infrared power meter is suitable for testing the infrared rejection performance of architectural film, automobile thermal insulation film, solar film, thermal insulation glass and solar equipment. It can be used to measure the radiation intensity (infrared power density) of infrared light sources (sun, infrared lamps, etc).
The side windshield heat insulation film is also based on the premise that it does not affect the owner's observation of the rearview mirror. In addition, the thermal insulation effect of the thermal insulation film is not directly related to the color depth. The coating process in the thermal insulation film is the key factor that determines the thermal insulation effect. The higher the thermal insulation rate, the stronger the reflection. Generally speaking, the thermal insulation film with a thermal insulation rate of 60% is already a very effective product.Car insulation filmThe technology of attaching automotive insulation film is very important. The film is actually a very delicate process. It is difficult to know whether it is detailed enough. Owners must be cautious when choosing a film beauty shop, because it is related to the quality of the film. The professional film shop has special processes and tools. There are at least ten kinds of tools required for each film link, and there will also be a dust-free film workshop. There are two kinds of tools used for rolling water, hard and soft. Before using hard scraping to roll out the water, stick a protective film to prevent damage to the insulation film, and then roll out the water.According to industry insiders, a successful insulation film technician usually needs professional training to fully master the construction skills of different models. If the film quality is not good, rework may be required. In addition, according to the staff of the after-sales service station of a car trade service company, if there is a problem with the film, the 4S shop will rework it for you for free. As for how to identify whether the film is qualified, the experts of the service station made the following suggestions:1. See if there is sand and air bubbles in the whole insulation film. If there are too many dust and bubbles, the owner can ask the 4S shop to repost for free.2. See if the corners are firmly pasted. The corners are the easiest to get into the sand, but also the most careful whether the technician is careful.3. Sitting in the car and observing whether there is any influence on the sight. Especially the front and side windshields.4. After filming, it is recommended not to lift the glass at will within a week.
