With the improvement of people's pursuit of quality of life, the reporter found that many household products such as building materials, electrical appliances and bedding in the market have played the antibacterial banner, and consumers are willing to buy these products in order to add health points. But is antibacterial products really so amazing like some businesses? Experts pointed out that the current antibacterial products field lacks the necessary supervision and the use of logos is confusing, and consumers should be cautious when purchasing.
Market articles business propaganda chaos sold in recent days, Jinghua home reporter found in several home and electrical stores in the West Fourth Ring, many categories of products all claim their own products antibacterial. The label of a sanitary ware shop directly marks “antibacterial productsâ€, and some of them have small labels with similar labels on them, which have “sterilization functionâ€. But when the reporter asked how antibacterial, the guide's answer was very confusing. A brand of shopping guide told reporters that the surface of the toilet has added a substance that can resist and kill various bacteria. Another well-known brand of shopping guide explained that their toilet seat is a resin material is not ordinary plastic, so antibacterial, see reporters expressed doubts, he changed the mouth to say that in fact, can not use antibacterial. When the reporter asked for a product inspection report from a brand sanitary ware salesperson, he said that the store did not, but when it was delivered, it would be put together with the product manual for the reporter.
In a paint supermarket, Jinghua home reporter saw that many brands of paint buckets were printed with the word "antibacterial". Some publicity released negative ions to play an antibacterial role. Some said that the products contained silver ions and could be antibacterial, but the reporters did not see the corresponding Test report. Flooring products also have antibacterial properties. The shopping guide of a well-known brand floor introduced that because the surface of the floor is sealed with wax, it is antibacterial. Another brand of floor guides introduced that their antibacterial floor adds some antibacterial agent to the substrate.
Many washing machines and air conditioners have also produced antibacterial signs. A washing machine brand shopping guide introduced that silver ion antibacterial is outdated, and silver ions will produce silver oxide to the body, and they now use 60 ° C steam for clothing and washing machines to kill a variety of bacteria. A brand of air-conditioning shopping guide told reporters that their air conditioners can emit negative ions to purify the air, antibacterial, and show the experimental report issued by a university. Another air-conditioning shopping guide showed reporters its nano-titanium filter purification antibacterial device. When the reporter asked for a test report, the shopping guide said: "I have no report, but these are definitely based on it. I can't talk about it."
Comprehensive interviews revealed that the guides explained the principle and function of antibacterial products very confused or even self-explanatory, and most of the antibacterial products are much higher than similar ordinary products.
Consumers do not know the principle of buying a dizzy reporter found in the store, although the shopping guide said it is not clear, but the "antibacterial" products still attracted the attention of many consumers.
Zhang Ayi, who wants to buy an antibacterial floor, said: "My one-year-old grandson is rolling on the ground all the time. He often puts things on the ground and puts them in his mouth. If you use antibacterial floor, there is no bacteria on the ground, I am not afraid that he is sick. Mr. Zhao, who is learning about antibacterial air conditioning, said that although he doesn't know much about the nanotechnology introduced by the guide, he heard that the air conditioner is particularly dirty. If there is antibacterial function, the indoor air quality will definitely be better, so it will still be considered. Air conditioner with antibacterial function.
Are various antibacterial technologies such as negative ions, silver ions, nanotechnology, etc. appearing on the market really effective? How long can their antibacterial effect last? For the various techniques introduced by the shopping guide, Jinghua Home reporter asked the relevant experts to conduct an analysis one by one.
Vigilant Technology Fudge Element Zheng Sujiang, deputy director and technical director of the Antibacterial Materials Testing Center of the Institute of Physics and Chemistry of the Chinese Academy of Sciences, pointed out that negative ions have not yet found antibacterial and sterilizing effects. The use of silver ion antibacterial is currently a safer method, and the statement that silver oxide is produced is purely flickering. For many nano-antibacterial technologies that many businesses hang on their lips and explain unclearly, Zheng Sujiang introduced that there are many branches of nanotechnology. It is feasible to use antibacterial, but it is necessary to explain what method is used. Otherwise, there will be suspicion of flickering.
Antibacterial is not a perpetual sterilization of the once-and-for-all business promotion? Deng Xiaohong, professor and chief physician of the Beijing Municipal Center for Disease Control and Prevention, said that there are many types of microorganisms in nature, and it is unlikely that propaganda can inhibit the growth of all microorganisms. The effective period of antibacterial function depends on the design and test data of the product. All propaganda should be based on evidence. Zheng Sujiang pointed out that the antibacterial product propaganda and sterilization function is very unscientific, because the country has clear regulations on sterilization time and sterilization rate, and some products can not meet the corresponding standards even if they can be sterilized.
Nano-titanium filtration depends on light. "The so-called nano-titanium should be titanium dioxide. It is generally applied to photocatalyst technology, so it must be illuminated to work." Zheng Sujiang pointed out that the air-conditioning filter is inside, and it is difficult to ensure lighting. As for the method of physically filtering bacteria, Deng Xiaohong said that this is a very good method in itself, but whether it is effective depends on the actual conditions of the filter device, and it is necessary to pay attention to whether it will cause secondary pollution.
Steam sterilization requires data for a washing machine guide introduced by the use of 60 ° C steam sterilization, Deng Xiaohong said that high temperature can indeed kill bacteria, but 60 ° C is absolutely impossible to kill all bacteria. Moreover, the action time of high temperature and the degree of pollution of clothes will affect the sterilization effect. She said that if all the bacteria can be killed, the data should be detected.
Was the wax sealed with the antibacterial layer sealed with a layer of wax to represent the antibacterial floor? Zheng Sujiang introduced the antibacterial agent of the floor to be added to the anti-wear layer of the surface to take effect. It is useless in the substrate, and the sealing wax has nothing to do with antibacterial.
The selection of the correct understanding of the appropriate selection of experts pointed out that in fact, consumer understanding of antibacterial products is not necessarily correct. Deng Xiaohong said: "The so-called antibacterial simplicity refers to inhibiting the growth and development of microorganisms so that they do not grow in number, but it only acts as a inhibitor, without reducing or disappearing microorganisms." She pointed out The qualified antibacterial products with antibacterial ingredients can only ensure that the existing microorganisms do not grow, and can not interact with other substances in the environment to produce antibacterial functions. This is to be understood by consumers. Taking the refrigerator as an example, if the inner wall is a bacteriostatic material, the inner wall of the refrigerator has an inhibitory effect on the microorganisms which are contaminated by itself, and the number of microorganisms placed on the food is still not changed.
Zheng Sujiang also pointed out that qualified antibacterial products can only ensure that they do not become a breeding ground for bacteria, and control the number of bacteria in a relatively safe range. Compared with common materials, it can reduce the chance of cross infection and improve the quality of life. There is gain. In an ordinary home environment, antibacterial products are not used in all places, and should be selected in areas with risk of contamination or according to their own needs.
He introduced that from the area, the kitchen and bathroom in the family are the places where bacteria can easily breed, so it is meaningful to use antibacterial materials for the kitchen boards and rags. If the bathroom towel is not washed in time, the use of antibacterial products can also reduce the odor (the bacteria will produce odor and sourness if it is excessively bred).
From the point of view of specific products, ceramics and floor tiles in building materials can be used in kitchens and bathrooms with high pollution risks. Deng Xiaohong believes that the floor usage rate is extremely high, and it will be contaminated with various microorganisms. Therefore, even if antibacterial technology is used, it is of little significance. If you are afraid of children contaminating bacteria on the ground, it is better to control them to crawl on the ground. Does the interior wall coating antibacterial have any meaning? Zheng Sujiang believes that the most important thing for coatings is to prevent mildew, and the cost of antibacterial technology itself is low. Manufacturers are likely to add antibacterial functions by the way to increase the selling point. In daily life, people rarely touch the wall. He believes that antibacterial significance is not great. . Experts also categorized the significance of the product's antibacterial function.
Bedding: Zheng Sujiang pointed out that the proper use of antibacterial bedding in people with allergies may help to alleviate symptoms.
Clothing: Antibacterial technology can be used in socks and underwear to reduce odor and increase comfort. Home appliances: buttons for various home appliances, refrigerator interior walls and fruit and vegetable boxes, door seals, etc., which are easy to breed bacteria, have antibacterial materials. In addition, the use of antibacterial technology in the barrel of the washing machine can also reduce the occurrence of odor, and the sensing window cushion of the drum washing machine can also be used to reduce the possibility of mold.
Experts also said that even the use of antibacterial products can not replace the daily cleaning, good hygiene habits are the basis for a healthy life. The hygiene problems caused by textiles, refrigerators, etc. can all be solved by washing, drying and cleaning. Deng Xiaohong also reminded consumers that the most important thing in daily home environment is to maintain hygiene, and the functions of antibacterial products are very limited.
Lack of regulatory review reports Currently, the country has established a number of national standards and industry standards to regulate the production of antibacterial products. For example, the antibacterial, sterilization and purification functions of household and similar electrical appliances to be released in September is the country that regulates the production of electrical appliances. standard. However, Zheng Sujiang pointed out that the field of antibacterial products still lacks the necessary supervision and the use of logos is also confusing. Therefore, consumers should ask the manufacturers for third-party test reports with qualifications for testing to determine the actual use function of the products. The credibility of the experimental report has to be discounted.
Experts also pointed out that if the selected product does not have relevant standard specifications, it should refer to the same type of product standard or foreign standard. In addition to functional test reports, you should also review their safety and hygiene standards, especially those that are in direct contact with the human body, and must request biosafety reports.
