■ Anti-static pen ■ Anti-static bracelet Anti-static spray The cold wave struck, the temperature plummeted, and the citizens wore sweaters and woolen coats. Along with this, many people suffer from static electricity. The faint tingling sensation not only makes people feel uncomfortable, but also affects people's daily communication. Recently, the Evening News Citizen Hotline 5589999 received calls from many public readers to inquire whether the online "anti-static artifact" was useful. The reporter purchased 3 more common anti-static products from the Internet to experience and found that there was a difference in the use effect. Text/Reporter Zhang Shi Wang Yingda Figure/Wang Yingda User Experience Large Differences in Time of Action Some product effects are mediocre Reporters searched for "anti-static artifacts" on a shopping platform, and purchased 3 different forms of products, such as anti-static bracelets, anti-static sprays and anti-static pens, according to sales, and invited experiencers to try them out. The prices of these products range from 5 yuan to 30 yuan. Among them, the bracelet product mentioned on the promotional page that after wearing it for one to two weeks, it can improve the situation of frequent static electricity, and serious static electricity may take three to four weeks, and the effect varies from person to person. Both other products claim to work immediately. Ms. Zhou, a citizen, is often plagued by static electricity. She conducts a trial and wears a bracelet for a day. "Static electricity doesn't seem to happen as often, but it's not impossible." She said that after wearing the bracelet, she forgot to apply hand cream after washing her hands, and there was still static electricity when her hands touched the sweater. Since the product requires a certain amount of time to wear and there is uncertainty about the wearing effect, she will continue to wear it for a period of time before making observations. Ms. Hui, a member of the public, tried to experience the anti-static spray and sprayed the spray on clothing. According to the promotion of the product, one spray can prevent static electricity from occurring for the next 168 hours (7 days). She said that she was prone to static electricity when she got on and off the bus on weekdays, and she did not feel static electricity during the half-day of the test. Ms. Xu introduced that the clothes sprayed with spray, under the same friction conditions, the static electricity generated did decrease, but the effect was flat, and if the effect was obvious, it was necessary to spray a large area, but this was obviously unrealistic, because no one wanted to wear wet scarves and wet clothes in the cold winter. Citizen Miss Lin tried to experience the anti-static pen. According to the merchant, the product is mainly to remove static electricity from the door handle of the car. It does work when actually tested. So she put the product on her car keychain. Professional statement Bracelet publicity is an advertising gimmick Anti-static pen is not necessary to buy Liao Yan, a physics teacher at Xiamen No. 11 Middle School, was interviewed by reporters and introduced his views on three products: Static electricity is the transfer of extranuclear electrons produced by the friction of two different substances, and has nothing to do with electrons in the human body. The anti-static bracelet advertises that "through the silicone containing negative ion energy elements, adjust the positive and negative ratio of human current, thereby eliminating static electricity", which is an advertising gimmick. Anti-static spray is equivalent to conducting the charge away through the spray, and has a certain anti-static effect. The principle of the antistatic pen is to contact the object first through the conductor, the charge is directed away, and when the hand touches the object, it can prevent electric shock. Therefore, as long as it is a conductor in life, this effect can be achieved, and there is no need to specifically buy products with special conductive materials. TipsHow does static electricity occur? Why is it always frequent in winter? It is understood that static electricity is a charge that is in a static state. It is the accumulation of charges on the surface of an object, and under normal conditions, the number of protons of an atom is the same as the number of electrons, positive and negative, and therefore not charged. However, once there are external factors that cause electrons to de-orbit, then there will be an imbalance in the distribution of electrons. With the arrival of autumn and winter, the air becomes drier and drier, people wear multiple layers of clothing, creating more friction opportunities (skin and clothes, clothes to clothes), and it is easier to generate static electricity. How to prevent static electricity? These tips are useful Air drying is a key factor in the generation of static electricity. Chen Zhihao, deputy chief physician of the Department of Cardiology of Xiang'an Hospital affiliated to Xiamen University, suggested that we can prevent static electricity by increasing air humidity. For example, use a humidifier indoors, or wipe objects with a damp cloth. At the same time, you can avoid wearing woolen clothes, chemical fibers and other materials, and change to wear pure cotton material clothes, it is not easy to generate static electricity. In addition, after undressing in winter, gently touching the wall with your hand can release the accumulated charge in the body, as well as before touching the door handle or hand tap; when washing clothes, add a little softener to reduce static electricity. Liao Yan, a physics teacher at Xiamen No. 11 Middle School, reminded that when everyone goes to special places such as gas stations, they need to beware of static electricity hazards. Because the oil products in the process of transportation and distribution and blending, it is very easy to generate static electricity and accumulate, becoming a potential hidden danger of fire and explosion. When you are refueling, you can eliminate static electricity by touching the metal keyboard or static electricity releaser on the fuel dispenser, or you can wash your hands or touch it on the wall and put your hand on the metal body to eliminate static electricity. Further reading Can Static Electricity Cause Heart Discomfort? Doctors say there are no related cases There is a saying that static interference may change the potential difference in the human body, affect the normal work of human organs, especially the heart, and may cause abnormal heart rhythm and premature heartbeat. In this regard, Chen Zhihao, deputy chief physician of the Department of Cardiology of Xiang'an Hospital affiliated to Xiamen University, said that after static electricity is generated, people will have an instant tingling sensation and other discomfort, but his clinical experience for more than ten years has not encountered cases of heart discomfort caused by static electricity, nor has he found patients who are treated because of static electricity, so it is impossible to confirm the scientific nature of this statement.
