As for the production technology of automobile heat insulation film, from the initial dyeing (coloring) process, vacuum electroplating aluminum film, vacuum electroplating aluminum layer and dyeing mixed film, magnetron sputtering metal film to magnetron sputtering multi-layer metal film, with the continuous progress of technology, the performance of products is also improving, and the production cost and price are quite different. However, at present, no brand in the market can clearly indicate which production technology it belongs to, but adopts the concept of confusion and introduces its products with the help of some scientific and technological terms.
At present, the varieties of automobile heat insulation and explosion-proof films on the market can be roughly divided into four categories from the manufacturing process: ① Dyeing black films (commonly known as black paper) and using low-quality dyes to color the installation glue. The mounting price is 150-300 yuan, which basically has no heat insulation and energy saving effect, and belongs to inferior film. (2) Thermal evaporation aluminizing composite dyeing layer metallized film, the installation price is 800 ~ 3000 yuan. It has a dyeing process, and the strong reflection of the thermally evaporated aluminum coating is shielded by the dyeing layer. This kind of membrane is the mainstream product at present, with large heat absorption and short decay period.
Primary color magnetron sputtering multilayer metal film, represented by the quantum automobile film produced by Bekaert, is at the leading level in the industry in manufacturing technology and installation technology. The installation price is about 2,500 yuan (excluding the front bumper and skylight), with reliable quality and superior performance.
Magnetron sputtering is a cutting-edge technology in the manufacture of automobile film at present, which is essentially different from the process of producing window film by dyeing and aluminizing which is still adopted by some inferior automobile film manufacturers in the early days or now. In the early 1980s, American Bekaert Company was the first window film manufacturer in the world to commercially produce window films by vacuum magnetron sputtering.
So what kind of film is a "professional solar film"? We can pay attention to the following aspects: the thermal insulation rate of professional solar films can generally reach 40%-79%. The concept of non-professional membrane is confusing, and the concept of "infrared blocking rate" is often regarded as "thermal insulation rate", and the reported value is even as high as 90%, which simply ignores scientific laws.
Professional solar films can maintain a high degree of clarity and transparency, and at the same time have a high thermal insulation rate. Sticking glass will not cause fuzzy deformation, but also can effectively filter dazzling glare.
Professional solar film adopts deep dyeing technology, and dyes are injected into polyester film substrate to make the film full, soft and durable. The fully metallized film produced by vacuum aluminum plating or magnetron sputtering technology has eternal color.
The outermost layer of professional solar film is plated with a hard scratch-resistant layer. For consumers, this scratch-resistant solar film is also convenient for the daily cleaning and maintenance of window glass, and will not leave scratches.
Professional solar films can block 99% of ultraviolet rays and continue to play a role, and the ultraviolet blocking rate of non-professional films is less than 50%.
Consumers should know more about the background of their manufacturers when choosing brands. Many brands boast that their brands are imported from the United States or South Korea, Japan, Taiwan Province Province and other places.
CCTV's Weekly Quality Report also specifically reported that these so-called well-known automobile film brands are actually registered by some domestic manufacturers and have nothing to do with other well-known brands in the industry. They are neither internationally recognized manufacturers, nor can they provide consumers with original products and original warranty. Both Bekaert quantum film and Shurejia automobile film are equipped with the latest digital anti-counterfeiting labels. Consumers can check whether your car film is Bekaert's original product by entering numbers through telephone, SMS and website, so as to ensure that consumers can buy genuine products on the market.
As an internationally recognized authoritative industry organization, the International Window Film Association (IWFA) has only certified eight companies including Bekaert and 3M in the world, and only a few of these eight companies have entered China as original factories. As the world's largest manufacturer of magnetron sputtering films, Bekaert Special Coatings Company is also an internationally recognized industry leader.
1995, the company invented a metal atomic film with a two-dimensional structure. Through mutual extinction of various metal films, the reflectivity of automobile films was greatly reduced, thus realizing a new generation of automobile films with high light transmittance, high heat insulation and low reflectivity. Because it represents a leap in industry technology, this product is registered as "quantum film" in the United States, and applied for the world patent number (W096 1339A 1) and the American patent (55 13040), and won the industry science and technology award again and again, making it unique in the industry!
