[China Glass Network] Recently, the Shanghai Quality Supervision Department released two vehicle-related product risk monitoring results: some automotive interior samples showed excessive formaldehyde emission; some automotive glass films have safety hazards.
A careless interior becomes a source of pollution
Passenger car interior materials, such as plastic products such as instrument panels, safety products such as safety belts, rubber strips such as sealing strips, rubber gaskets, etc., organic volatiles, aldehydes and ketones, and odors may be emitted from composite products containing adhesives. As a source of air pollution in the car, there is a risk of quality and safety.
The Shanghai Municipal Quality Supervision Bureau conducts quality and safety risk monitoring on passenger car interior materials in the production area of ​​this Municipality. According to relevant standards, risk monitoring of organic volatiles, aldehydes and ketones (benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde) and odors emitted by passenger car interior materials was carried out.
A total of 50 batches of samples were collected for risk monitoring. After testing, 3 batches did not meet the requirements and there was a safety risk. One batch of the products did not meet the requirements of formaldehyde, ethylbenzene and xylene. The toluene, ethylbenzene and xylene of one batch of products did not meet the requirements, and the formaldehyde of one batch of products did not meet.
Inferior glass film compromises safety
The Shanghai Quality Supervision Bureau also found that the membrane for glass used in the safety monitoring of automotive glass has safety hazards.
The three main functions of automotive glass film are heat insulation, UV blocking, and prevention of accidental glass bursting. The quality of the film for automotive glass on the market is mixed and varied. Consumers who choose improperly or use inferior membranes will not only achieve the desired results, but also affect driving safety.
A total of 10 batches of samples were collected from the risk monitoring conducted by the Shanghai Municipal Quality Supervision Bureau. After testing, 5 batches of automotive glass film did not meet the requirements. They were all films for the windshield of automobiles, and there were 1 batch of products with visible light transmittance. The UV transmittance is not satisfactory, the UV transmittance of one batch of products does not meet the requirements, and the total solar transmittance of the three batches does not meet the requirements.
According to the Shanghai Quality Supervision Bureau, a film with a low visible light transmittance will cause the driver to be unable to see the objects outside the vehicle, directly affecting the driver's observation of the driving environment, resulting in safety hazards in the driving. A film with a high UV transmittance and a high total solar transmittance does not block ultraviolet rays and heat.
After buying a better car mats do not immediately <br> with <br> we buy the vehicle interior parts or maintenance, to ensure quality and avoid using the "three noes" products. When the vehicle is being rehabilitated, the water-based polyurethane adhesive for the interior of the car can be used to reduce the emission of gas from the interior material. After purchasing the car mat, it is better to put it in the ventilated place for 1-2 weeks, and then put it into the car.
To purchase a film for automotive glass that meets the quality and safety, you can identify the film by four simple methods: 1 Cut a small film, observe the distant object through the film, or put it Observe the writing on the background of black and white on the white paper; 2 Place the film in front of the infrared lamp or iodine-tungsten lamp, and feel the temperature change by hand across the film. If the temperature changes quickly, the heat insulation performance is not good; 3 wipe with a soft cloth. Membrane surface, film with fading and obvious scratches is inferior product; 4 tearing the back film to smell, the inferior film has more residual solvent and odor.
Everyone wants to go to a regular business to buy branded products. When purchasing, you should check whether the product has relevant information, such as product name, model, manufacturer or agent, and ask for product performance parameter data. The information is unknown or cannot provide performance. The parameters of the product are carefully purchased.
