[China Glass Network] Recently, Jiangsu Yancheng Quality Supervision Bureau was commissioned by the Jiangsu Provincial Quality Supervision Bureau to carry out risk monitoring for the quality of automobile window glass sunshade products. The test results show that the monitoring results of 102 batches of automobile window sunshade film, light transmittance, ultraviolet transmittance, tensile strength, tensile elongation and other indicators are in line with the relevant national standards of only 30 batches, the rate of compliance 29.4%. Among them, the car 4S shop compliance rate is 25%, the network e-commerce platform compliance rate is 20%, and the physical store compliance rate is 31.2%. Experts remind consumers that the quality of automobile window glass sunshade products is mixed, and consumers should guard against fake "brands" when purchasing.
Inferior car film affects safety
China's automotive glass sunshade market is relatively chaotic, mainly in the small industry, low-skilled small enterprises, small workshops exist in large numbers, many products "å‚ brand", "cottage" confusing people, because of low cost, large profits It has formed a "profit chain" with a profit of 10 times or even 10 times, so that the industry has the saying that "selling a film to make money than selling a car". The survey found that the car's film rate is as high as 91%. However, the owners are basically unaware of the brand, quality, price and service knowledge of their chosen film. They are basically in the position of listening to the store, pricing by the seller, and paying for themselves. On the other hand, the automobile window glass sunshade industry still has no uniform and compulsory product standards, and the domestic professional testing and research on this product is basically in a blank state.
Before the implementation of the monitoring, the sampling monitoring randomly conducted a consumption questionnaire survey on 200 car owners in use, of which 182 cars were selected, accounting for 91%. According to the survey results, 76% of consumers pay more attention to brands when choosing film; 55% choose to apply film in 4S shop, 31% in car decoration shop, 16% through online shopping, and 15% are car gifts; 50% of consumers choose domestic brands, and 40% choose imported brands.
The results of the sampling monitoring show that there are a large number of small enterprises and small workshops. These companies adopt the â€œå‚ brand†model to launch cottage products, such as “Johnson Titaniumâ€, “Johnson 99â€, “Dragon Film Extremeâ€, “Weigu璀璨â€, “3M Titaniumâ€, “Infrared Quantumâ€, etc. When registering a trademark, it is intended to add a few words after the name of the big brand. In fact, this film has nothing to do with the brand film.
Followed by OEM, the so-called OEM is only for the big brand OEM, shackled by the technical blockade, the products launched can only be high imitation automotive film, and then write "American film, Japanese film", etc., its function is far Not as complete as it claims. These miscellaneous inferior membranes are mostly concentrated in the auto parts market and e-commerce platform. In addition, some automotive 4S shop customized automotive film, such as a certain car special film, etc., many product packaging marks are not complete, no product origin, factory name, factory address, etc., the price ranges from 1 to 20,000 yuan, in fact, automobile manufacturing companies No production of automotive film, no special one. Therefore, experts recommend that consumers recognize these brands, choose a full range of products, do not blindly from the 4S shop's automotive film, the quality of the gift film products must also meet the standard requirements.
What are the hazards of inferior automotive films? Experts said that first, poor quality automotive film stability is poor, easy to aging deformation, low light transmittance, will lead to reduced clarity, easy to produce light refraction, easy to make the driver's eyes fatigue, affecting driving safety. Second, the residual solvent content of the rubber layer is high. When exposed to the sun, the organic substances in the rubber will be slowly released, and volatile substances such as formaldehyde and benzene will be volatilized, causing damage to human health. Third, the inferior automobile glass film can not resist ultraviolet rays, but it will lead to high temperature inside the car, increase the load of the air conditioner, and increase fuel consumption. In addition, due to the lack of toughness of the inferior automobile glass film, when the external force is hit, the glass will splash open, which seriously affects the personal safety of the owner.
7 major methods to distinguish between good and bad
At present, the car sunshade products on the market, if you choose the mid-range price, such as Johnson & Johnson, 3M, DuPont, etc., the price of each car is 1,500~3000 yuan. High-end, such as the ball window film, quantum, Weigu, etc., the price is usually more than 3,000 yuan, or even 10,000 yuan. If the vehicle grade is higher (more than 500,000 yuan), you can not use the film. When purchasing a car foil, consumers should check whether there is a manufacturer, a trademark, a specification model, a test report, and a manufacturer's warranty card. The manufacturer's warranty card usually contains the manufacturer's name, phone number, and address that can be found. Generally, some powerful manufacturers will provide some solar film testers for customer testing to verify the authenticity of the parameters on the manual. Whether in a regular 4S shop, a professional film company or a variety of car beauty shops, accessories stores, consumers can roughly identify the film products according to some simple factors:
Regardless of the color of the film, the high-quality film should be able to clearly see objects 6 meters away at night, and the inferior film will have a misty feeling.
The genuine film feels thick and smooth, while the inferior film feels thin and brittle and easy to wrinkle.
The high-quality film pigments are durable and not easy to change color. They will not be discolored by the scraper during the sticking process. The color of the inferior film sometimes falls off on its own. The surface of the film can be wiped with alcohol or gasoline, and the inferior film is easily faded.
When the plastic lining of the car foil is torn off, and then recombined, the inferior film will foam, and the high-quality film will be as good as before.
A test method can also be used for comparison: placing a glass of car foil on a iodine-tungsten lamp, the hand does not feel a trace of heat is a high-quality film, and immediately a hot feeling indicates its thermal insulation performance. There is a problem, it is a poor quality film.
When purchasing the film (including 4S shop gift), let the merchant clearly write the product specifications, batch number and other relevant parameters of the film on the invoice or warranty card, and ask for the sample of the film (150mm × 80mm), and properly save the sample and other information. , can effectively defend rights during the warranty period.
The film should be replaced in time after use for a period of time. According to different grades, the interval is about 5~8 years.
