Recently, Beijing Mercedes-Benz Automobile Co., Ltd. and Mercedes-Benz (China) Automobile Sales Co., Ltd. filed a recall plan with the AQSIQ according to the requirements of the Regulations on the Management of Defective Automobile Product Recall, which was decided from April 28, 2017. From the date of the recall, a total of 146 vehicles will be recalled to the Mercedes-Benz authorized dealers for software upgrades from December 3 to December 5, 2016:
(1) Beijing Benz Auto Co., Ltd. recalled some C-class, E-class, GLA-class, GLC SUV and GLK-class vehicles produced from July 14, 2010 to December 17, 2016, a total of 83 vehicles;
(II) Mercedes-Benz (China) Automobile Sales Co., Ltd. recalls some of the imported A, B, E, M, S, and GL produced from October 1, 2008 to September 15, 2016. Level, CLS, GLK, CLA, GLE SUV, GLC SUV, smart vehicles, a total of 63 vehicles.
The software of the vehicle within the scope of this recall is incorrectly coded during the upgrade, which may affect the function of the relevant control unit, resulting in the airbag being erroneously popped up, or the control unit may not correctly detect the use of the seat belt, which may present a safety hazard. Mercedes-Benz (China) Automobile Sales Co., Ltd. and Beijing Benz Auto Co., Ltd. will upgrade the control unit software for vehicles within the scope of the recall to eliminate potential safety hazards.
The Mercedes-Benz Authorized Service Center will notify the customer about the recall by registered mail. At the same time, users can also call the service hotline for consultation. Owners can also visit the AQSIQ Defective Product Management Center website () and the WeChat public account (AQSIQDPAC) for more information. In addition, you can also call the Quality Hotline of the Defective Product Management Center of the AQSIQ or the quality hotline of the local entry-exit inspection and quarantine institution: 12365 (switch No. 2) to reflect the problems in the implementation of the recall activity or to submit defects.
Thermal Break Windows Extrusion Dies
Broken bridge aluminum doors and windows are a relatively common door and window product on the market. They have received widespread attention and application in the construction industry for their unique design and excellent functions. The principle of broken bridge aluminum doors and windows is to achieve thermal insulation, sound insulation, energy saving and other effects by interrupting the heat conduction between the two layers of aluminum profiles inside and outside the door and window frame.
The design concept of broken bridge aluminum doors and windows is derived from the basic principle of heat conduction. Aluminum alloy is a material with good thermal conductivity, and the double-layer frame structure of doors and windows will cause energy loss due to heat conducted indoors and outdoors through doors and windows. In order to solve this problem, broken bridge aluminum doors and windows adopt broken bridge technology, that is, a layer of broken bridge aluminum profiles is set between the inner and outer layers of the door and window frame. The special design of this aluminum profile effectively prevents the conduction of heat, thereby achieving a good heat insulation effect.
The thermal insulation effect of broken bridge aluminum doors and windows is mainly reflected in the following aspects:
1. The use of thermal bridge aluminum profiles
The key technology of broken bridge aluminum doors and windows is the use of thermal bridge aluminum profiles. This kind of profile is filled with materials with low thermal conductivity, which prevents the conduction of indoor and outdoor heat. At the same time, heat insulation strips are installed on both sides of the aluminum profile to further reduce heat transfer. These designs make the broken bridge aluminum doors and windows have good thermal insulation properties and can effectively reduce the energy consumption of indoor air conditioning.
2. Two-way sealing system
In addition to using thermal bridge aluminum profiles, broken bridge aluminum doors and windows also adopt a two-way sealing system. This sealing system can effectively prevent the penetration of air and water, improving the sealing performance of doors and windows. Through good sealing performance, broken bridge aluminum doors and windows can prevent the transfer of hot and cold air, keep the indoor temperature stable, and provide a comfortable living environment.
3. Multi-layer soundproof glass
Sound insulation performance is also a major feature of broken bridge aluminum doors and windows. In order to improve the sound insulation effect of doors and windows, multi-layer sound insulation glass is used in broken bridge aluminum doors and windows. This kind of glass has high sound isolation performance and can effectively reduce the transmission of indoor and outdoor noise. Especially in bustling areas or places with high noise, broken bridge aluminum doors and windows can provide residents with a quieter living environment.
4. Energy conservation
The thermal and sound insulation properties of broken bridge aluminum doors and windows not only provide residents with a comfortable living environment, but also save energy. By reducing the transfer of indoor and outdoor temperatures, broken bridge aluminum doors and windows can reduce the frequency of air conditioning use and energy consumption, thereby achieving the purpose of energy saving and emission reduction. With long-term use, this will have a positive impact on environmental protection and sustainable development.
in conclusion
As a door and window product with good heat insulation, sound insulation and energy-saving properties, broken bridge aluminum doors and windows are favored by many consumers. Its principle is to improve the heat insulation effect of doors and windows by cutting off the heat conduction between the inner and outer layers of aluminum profiles. At the same time, the broken bridge aluminum doors and windows also use a two-way sealing system and multi-layer soundproof glass to further improve the performance of the doors and windows. By saving energy and providing a comfortable living environment, broken bridge aluminum doors and windows have made important contributions to people's quality of life and environmental protection.
