Recently, the Jiangsu Yancheng City Bureau of quality supervision by the Jiangsu Provincial Quality Supervision Bureau commissioned, according to automotive window glass sun shading film product quality to carry out risk monitoring. Test results show that: the 102 batch monitoring car window shading film, 4 indicators of light transmittance, ultraviolet transmittance, tensile strength, tensile elongation accord with the relevant national standards only 30 batches, the coincidence rate was 29.4%. Theautomobile 4S stores the coincidence rate is 25%, the network business platformcoincidence rate is 20%, the entity stores the coincidence rate was 31.2%. Experts remind consumers, quality uneven, some good and some bad car window glass sun shading film products, consumers should extend security "brand".
Inferior car impact safety
Automotive glass sun shading film market in China is quite chaotic, mainly in theindustry lower the threshold, pretend to play the Yu small enterprises, small workshops exist in large quantities, many products "draw near famous brand", to"copycat" or people or the world, because of low cost, profit, forming a "profiteeringchain", 10 times the profit up to even 10 times the number, so that the industry has"sell film than make money selling cars". The survey found that, car film rate was as high as 91%. But the owners of their chosen film brand, quality, price and service knowledge basic point is not known, basically in the listen stores publicity, by the Seller pricing, pay their status. On the other hand, the car window glass sun shading film industry is still not unified, mandatory product standards constraints, domestic about the detection and study of the products for the professional basically blank.
In the monitoring of the implementation of the former, random sampling monitoring of 200 car owners use, carry out consumer questionnaire, which select the mask of 182 vehicles, accounting for 91%. According to the results of the survey, 76% of consumers in the choice of film, the main attention to brand; 55% of consumers choose to shop in the 4S film, 31% in the car decoration shop film, 16% throughonline shopping, purchase a car 15% is presented; 50% consumer brand choice made in China, 40% choose import brand.
Sampling monitoring results show that: pretend to play the Yu small enterprises, small workshops in the presence of a large number of. Many of these enterprises to take the "near the famous" model launches copycat products, such as: "Johnson titanium gold", "Johnson 99", "Dragon film supreme", "V-KOOL," bright "3M titanium gold","infrared quantum", registered trademark name brand after intends to add a few words this film, actually a little relationship with the brand film No.
The second is the ODM, OEM only so-called big brand OEM, limited by the technology blockade, the launch of the product also can be a high imitation automotive film, then write "American membrane, the Japanese film", its function is far better than itsclaimed so complete. These inferior inferior films are more concentrated in the auto parts market and business platform. In addition, some automobile 4S shop customer automotive film, such as certain automobile special membrane and so on, a lot ofproduct packaging logo incomplete, no product origin, factory name, site and so on,the price 1 ~ 20000 yuan, in fact, automobile manufacturing enterprise is not the production of automotive film, no special one. Therefore, experts suggest that consumers recognize the brand, choose to mark complete products, automotive filmdon't follow the 4S shop, gift car product quality must meet the standard requirements.
Poor car film what harm? Experts said, one is the poor car membrane stability is poor,easy to aging deformation, light transmission rate is low, will lead to the definition ofreduced, easy to produce the refraction of light, easy to make eye fatigue of the driver, affecting the traffic safety. The two layer is the residual solvent content washigh, sun exposure, organic matter glue will slowly release, volatile formaldehyde,benzene and other harmful substances, causing damage to the health of human body. Three is a poor car glass film and can resist ultraviolet radiation, but will lead tothe high temperature inside the car, increase the air-conditioning load, the fuel consumption increase. In addition, poor car glass film due to the lack of toughness, by the external shock, the glass will splash open, seriously affect the owner's personal safety.
The 7 method to distinguish the merits
Currently on the market for automobile sunshading film products, if you choose the median price, such as Johnson, 3M, DuPont, every car sticker price in the 1500~3000 yuan. The high-end, such as global window film, quantum, V-KOOL and so on, the price is usually 3000 yuan, or even million yuan. If the vehicle is high grade (500000 yuan), can not mask. Consumers in the purchase of auto film, to see whether themanufacturers, trademarks, specifications, test reports and the manufacturer'swarranty card, warranty card manufacturers usually contain real homing manufacturer name, phone number, address, etc.. The general strength of the manufacturers, will provide some solar film tester for customers to test, to confirm the authenticity of theparameter specification. Both in the formal automobile 4S stores, or professional filmcompany or of various automotive beauty shop, accessories shop, consumers can beaccording to some simple factors are roughly the identification of film products:
Whether the film color depth, high quality films should be able to clearly see the 6 meters away from the objects in the night, and poor quality film will be foggy feeling.
Authentic film feels a thick smooth feeling, but feel inferior film is thin and crisp, easy to wrinkle.
High quality film pigment durable, not easy to change, in the process of scrapingpaste will not decolorization by the scraper coating. And poor quality film coloursometimes fall by themselves. You can use alcohol or gasoline wipe the surface of the film, the film is inferior fade easily.
When the plastic lining torn automotive film, re composite, inferior film foaming, and high quality film composite after intact.
You can also use a test method to compare: in an iodine tungsten lamp on a piece ofstick auto film glass by hand, feel a little heat is high quality film, and immediately hotfeeling is that the heat insulation performance problems, is inferior to film.
Buy film (including the 4S store gift) to allow merchants to product specifications,batch number and other related parameters of film clearly written on the invoice orwarranty card, and ask for the film sample (150mm * 80mm), and properly keep thesample data, in the warranty period can be effective in adults.
The car should be replaced after a period of use, according to the different grades of products, about interval in 5~8 years. |
