In recent years, with the rapid development of China's automobile industry, automobiles have entered millions of households, and some parents have begun to pay attention to child safety seats. However, is the safety seat on the market really safe? According to experts, the child safety seat products on the Chinese market are currently uneven. Consumers need to keep their eyes open when they purchase. If they buy quality-safe seats, then the safety seats are just like a dummy. Children's safety is the same. Not guaranteed.
Most of them did not have safety certification. Recently, the reporter went to an auto parts city in Beijing's North Fourth Ring, where he operates a variety of automotive supplies and spare parts. After several inquiries, the reporter found that only a few merchants sell child safety seats, and the product brand is relatively single. When asked how to ensure the quality of the child safety seat sold, the dealer said that when purchasing a child safety seat, an insurance company's accident insurance will be obtained. This kind of reply does not satisfy the reporter. In the sold safety seats, the reporter failed to find a text description and quality certification mark on the product material.
The reporter went to another auto parts city, and there are not many child safety seat products. There are still no signs that can prove its safety in product packaging and products. However, in some slightly graded malls, the reporter accidentally discovered a relatively more child safety seat. For example, at Lufthansa Shopping Center, the reporter saw a product of a foreign brand worth about 4,000 yuan. An icon was printed on this seat. The salesman explained that it was a Dutch safety certification mark, indicating that the product passed the exporting country. The rigorous test of the testing organization, that is, the safety protection performance of the child seat was tested through the impact test method, and the quality and safety are guaranteed. This is also a basic criterion for consumers to select the child safety seat.
It is understood that in the domestic market, there are very few products with similar safety certification marks. Most child seats have neither domestic nor foreign certification. According to a dealer, even if some domestic products have quality and safety certification, most of them are foreign certification marks. Because there are currently no relevant industry standards for child safety seats in China, some export brands can only go abroad to do crash tests and obtain safety certifications before they are sold in foreign and domestic markets. However, such products are generally expensive. In addition, some small processing companies do not have this strength, so they do not do collision tests at all and sell directly on the market.
The level of production technology and R&D needs to be improved. Because the safety and safety performance of child safety seats is directly related to the safety of children's lives, many countries and regions have corresponding standards. For example, the United States FMVSS standard, the European ECE-R44/03 standard, and the Japanese security standard all put forward specific regulations and standards for child safety seats (restraint systems). These standards all have strict technical requirements for the quality and safety of seats. For example, the Japanese standard checks the backrest height feel of the seat and the size of the buckle. In the relevant regulations in the United States, specific requirements for the abrasion resistance, light resistance, and microbiological strength of the fabrics are proposed.
In terms of child safety seats, our country must lag behind in terms of standards and technology. However, experts in the industry stated that from the manufacturing technology point of view, currently domestic manufacturers have the production capacity of child safety seats, but in technology and R&D tests, they basically rely on the support of foreign manufacturers, and most of them are used for export. . On the other hand, some domestic manufacturers have begun to realize the huge market potential in child safety seats and are currently developing this area. However, due to the lack of corresponding technical regulations and technical support in the field of trials, this has led to the The development of the sector has been subject to certain restrictions.
Children's car safety is valued Due to the rapid growth of private cars in recent years, it is understood that children's car safety issues that have been neglected in China have begun to improve. However, as the corresponding children's travel safety propaganda work and the development of supporting standards and regulations are still in their infancy, relevant experts have stated that there is still a lot of work to do in the use and popularization of car child safety seats.
It is understood that the China Automotive Technology and Research Center (hereinafter referred to as the China Automobile Center) has introduced an accelerated analog collision vehicle, which not only provides services for the export certification of domestic enterprises, but also provides a hardware platform for the research and development of enterprises. The reporter recently watched the crash test of the child safety seat at the China National Automobile Industry Center and felt the importance of the safety seat for the child's ride. According to reports, this year, China will begin to implement the National Standard for Vehicle occupant restraint systems. The standard is a mandatory national standard. After the standard is released, all domestic automobile manufacturers and seat manufacturers must produce child safety seats that meet this standard.
According to the relevant technical personnel of the China National Automobile Industry Center, this standard is based on the European ECE R44/04 standard, that is, according to the standard, domestic automobile manufacturers and seat manufacturers must provide seats with ISO FIX fixed interfaces. Therefore, after purchasing the child safety seat, consumers should choose the seat with ISO FIX fixed interface.
Experts said that although China's auto parts market is not yet mature, there is still a process for children’s safety awareness. However, with the introduction of standards and the continuous understanding of the importance of child safety seats by manufacturers and consumers, I believe that the market will be more and more perfect soon.
2. It is related to the physical properties of the material, the fluidity of the material and the uniformity of the particles. Some materials have poor fluidity, many impurities, high solvent content, and there may be blockage in the production process. At this time, it is necessary to use special equipment to do it. Not all materials can be crushed with standard equipment to achieve the fineness of crushing.
3. It is related to the crushing pressure in the crushing process. Some equipment feed pressure is greater than the crushing pressure, and some equipment crush pressure is greater than the feeding pressure.
4, and feeding speed has a relationship, not all the material mobility is good, whether it is the use of screw feed or vibration feed, feeding process is a very important factor, some very fine material is difficult to feed, at this time you need to use a special personalized configuration to achieve the feeding effect.
5. It is related to the optimization degree of air mill. There are many manufacturers of air mill, but the fineness of the same material is different from that of different manufacturers, even if the fineness of different models of equipment from the same manufacturer is different. But as a rule of thumb, devices that are larger than the shredder plate produce better results than smaller ones.
6. The operation method is related to the proficiency of the operator. Some equipment needs to be started with small pressure operation first, and some directly operate in one step.
It can be seen from the above that the fineness of the airflow mill is not fixed, but adjustable. Because of this, it has become a favored processing equipment in various industries, which can meet the diverse needs of different users.
