1: thermal insulation of dragon film: In summer, the solar control window film can block the huge heat energy of harsh sunlight, and can block up to 79% of the solar heat from entering the room, helping the buildings and offices to be more cool. In winter, the low-radiation sunlight can control the LOW-E film, which can reduce the external heat dissipation, reduce the heat loss by 30% and keep the indoor temperature.
2: 3m thermal insulation film: it has the function of heat insulation and energy saving, and has the functions of regulating indoor glare, blocking ultraviolet rays, preventing privacy and improving building appearance. 3M thermal insulation film is not only the inventor of solar thermal insulation film, but also the holder of the most advanced technology of solar thermal insulation film, with the most advanced performance and the longest warranty period in the industry.
3. Ray-Ban products come from two international professional parent factories in the United States and Japan, both of which have a history of more than 70 years. Among them, the American parent factory is one of the nine members of IWFA Thermal Insulation Film Association, and the high-end thermal insulation film produced has excellent characteristics such as high heat insulation, high transparency, privacy and protection.
Two: the difference between safety and explosion-proof:
1: The substrate of Dezhou film is a multi-layer tough polyester film, which is compounded with a special adhesive and then stuck to the glass surface to form an invisible barrier. Prevent glass splash damage caused by natural disasters, terrorist explosions, theft and invasion, ensure personal and property safety, upgrade existing glass windows to meet safety standards, with low cost and quick operation.
2: 3M explosion-proof film is a kind of 3M window film, which is attached to the glass to improve the safety of the glass without changing its appearance. The 3M explosion-proof membrane for building is basically a fully transparent product, and the main goal of automobile glass is usually heat insulation. Dyeing, metallization or multilayer optical film technology is used to increase the safety of glass while insulating heat.
3. Ray-Ban's main outstanding aspect is his poor insulation in explosion protection.
Three: the price difference:
1: Ray-Ban car film: good transparency and various colors. Disadvantages: There are many fakes on the market. Price: the front gear plus the body should be around 2000 yuan. ?
2. Dragon Movie: The quality of user response is good. Disadvantages: there are few dealers and it is not easy to find. Price: 2500-3000 yuan?
3: 3m car film front bumper plus car body is about 2000-3000 yuan.
Extended data:
Compared with Ray-Ban and Dragon Film, 3M automotive film has the following scientific and technological advantages:
1: ultra-fine coating: high-tech coating technology ensures the synchronous efficiency of light transmission and heat insulation. The world's leading coating technology enables 3M to cover thousands of optical molecules nearby in a thin optical film, which is a patented technology owner beyond any thermal insulation film manufacturer.
2. Thin film technology: the guarantee of high-strength heat insulation and explosion-proof film. 3M high-strength film production technology has been widely used in military, security and other fields. It is widely used by government secret departments, senior banks and commercial buildings all over the world.
3. Grinding: wear-resistant technology, leading the world. 3M is not only famous for grinding technology, but also introduces wear-resistant technology into the process of producing thermal insulation film products, so that the wear-resistant substrate can withstand the long-term use needs of customers.
4. Glue: patented glass bead glue technology, leading the world. 3M Unique World's professional viscose production technology ensures that the adhesive layer of thermal insulation film remains stable and does not fade for a long time in the sun exposure environment, while maintaining the requirements of visual clarity of thermal insulation film products.
