Warm baby temperature of up to 58 degrees, these products scald probability is extremely high-tinyos

"Warm baby" temperature of up to 58 degrees, these products scald probability is extremely high, these days you are "cold" to?. With the cold weather, the reporter saw in the streets of Wenzhou, businesses have started to put on a variety of "warm" products, of course, electric hot water, warm paste heating (Nuan Baobao) and "artifact". However, the reporter found in the visit, these heating products, especially warm paste, some turned out to be "three noes" products. Reporters learned from the city hospital of integrated traditional Chinese and Western medicine, every year December to January next year, the hospital will be admitted to many low temperature scald patients, many of which is due to the use of bad warm paste or improper use caused. In this issue of the news lab, we will walk into the laboratory of the school of chemistry and materials engineering, Wenzhou University, and ask Dr. Li Zhongyu to tell us the mystery of warm sticking and how to use it properly. In case of improper use of scald warm paste girls burn blisters stuff (a pseudonym) is a primary school in the fourth grade female students, because of a cold, in the winter, she cannot do without hot water bag, warm paste. Recently, she was in her school in the vicinity of the store to buy a "three noes" warm paste, one night sleeping, put it in the body, although the packaging to be used across the clothes, but she "capricious" the warm paste directly attached to the stomach, it woke up and found the skin the skin is red hot, even hot blisters. After a doctor’s examination, Dongdong is deep two degrees low temperature burns, has damaged the dermis layer, not only will leave scars, if not handled properly, but also cause skin ulcers. Xu Jie, deputy director of Department of Dermatology, hospital of integrated traditional Chinese and Western medicine, said that every year from December to January next year, the outpatient department will treat many patients who suffer from low temperature scald due to improper use of warm paste. Most of the patients are junior high school students, and more girls than boys. In general, the contact temperature of 70 DEG C for one minute, or touch a temperature of 60 DEG C for five minutes or more, are likely to cause burns; and warm paste temperature can reach more than 50 DEG C, even more than 60 degrees, so the skin is dangerous. In the reporter visited around the campus store sale of "three noes" warm paste on the front, the reporter visited the city sales warm paste shop, including more than primary school around the store. A shop near the downtown puxieshi primary school, the reporter asked whether the store sells warm paste, stores "have repeatedly response", and pointed to the door of a box on the ground says: "here is, you just pick." Reporters found that there are at least 8 small cartons of heating products, priced at 2 yuan to 8 yuan. Store owner picked up a "mini heater" said: "this student likes, in class, you can directly take in the hands of heating, very convenient, as long as 3 yuan."." But in this "mini heater" on the outer package, the reporter did not find any production date, quality certificate and manufacturers information, ask the cause of the store, the store also can not tell. 8 kinds of heating products sold in the shop, the reporter found that there are a number of "three noes" of products, like a transparent plastic packaging hand warmer, packaging is liquid and a piece of a dime sized iron, iron will simply press the automatic heating, duration of about 1 hours, but the reporter picked up the hand warmer, you can smell.

“暖宝宝”温度可达58℃ 这些产品烫伤概率极高这些天你是否被“冷”到了。随着天气转冷,记者在温州市区街头看到,商家已陆续摆出了各种“暖”产品,当然少不了电热水袋、暖贴(暖宝宝)等取暖“神器”。然而记者在走访中却发现,这些取暖产品中,特别是暖贴,有些竟然是三无产品。记者从市中西医结合医院了解到,每年12月至次年1月,该院都会收治到许多低温烫伤的患者,其中不少就是因为使用了劣质暖贴或者使用不当所造成。本期《新闻实验室》,我们将走进温州大学化学与材料工程学院的实验室,请李钟玉博士来说说暖贴发热的奥秘,以及该如何正确使用。■烫伤事例暖贴使用不当小女生被烫出水泡东东(化名)是市区一所小学的四年级女学生,因为怕冷,一到冬天,她总离不开热水袋、暖贴。最近,她在自己学校附近的小店买了一种“三无”暖贴,一到晚上睡觉,就把它贴在身上,虽然外包装上说明要隔着衣服使用,但她“任性”地将暖贴直接贴在了肚子上,结果一觉醒来,发现皮肤都被烫红了,甚至还烫出水泡。经医生检查,东东是深二度的低温烫伤,已经损伤到真皮层,不仅会留疤,如果处理不当,还会引发皮肤溃疡。市中西医结合医院皮肤科副主任医生许洁介绍说,每年12月至次年1月,门诊都会收治许多因暖贴使用不当而导致低温烫伤的患者,患者中初高中生居多,且女生多于男生。一般情况下,接触70℃的温度持续一分钟,或是触近60℃的温度持续五分钟以上时,都有可能造成烫伤;而暖贴的温度基本能达到50℃以上,甚至超过60℃,因此将其贴在皮肤上是存在危险性的。■记者走访校园周边小店有售“三无”暖贴日前,记者走访了市区有销售暖贴的小店,包括多所小学周边的小店。市区蒲鞋市小学附近一家小店,记者询问店家是否有卖暖贴,店家连声应答“有有有”,并指着门口一个放在地上的纸箱说:“这里都是,你随便挑。”记者发现,小纸箱里至少有8种取暖产品,售价在2元到8元不等。店家随手拿起一款“迷你取暖器”说:“这个学生很喜欢,上课的时候,可以直接拿在手里取暖,非常方便,只要3元。”但在这款“迷你取暖器”的外包装上,记者没有找到任何生产日期、质量合格证以及生产厂家的信息,询问店家原因,店家也说不清。该店出售的8种取暖产品中,记者发现有多款都是“三无产品”,像是一款塑料透明包装的暖手宝,包装内是流动液体和一片一角硬币大小的铁片,只要按下铁片就会自动发热,持续时间约1小时,但记者拿起该暖手宝,就能闻到一股难闻的金属气味。随后,记者又走访多家小学的周边小店时,均有发现类似的“三无”取暖产品,其中有商家坦言,有些产品确实没有厂家信息,但因为价格便宜,很受学生喜爱。■新闻实验发热温度根据成分用量调节这些取暖产品,包括暖贴,它们发热的原理是什么?本期《新闻实验室》,记者走进了温州大学化学与材料工程学院的实验室,请李钟玉博士来解答这其中的奥秘。◆实验准备:实验材料:铁、蛭石、活性炭、无机盐、沸石、水实验器具:小烧杯、玻璃搅拌棒、温度计、小吸管、电子秤◆实验过程第一步,用电子秤依次称量好所有需要的铁、蛭石、活性炭、无机盐、沸石等的重量,将其放入小烧杯中,最后再倒入适量的水。李博士解读:现在市面上所售的暖贴产品,其成分基本是铁、蛭石、活性炭、无机盐、水等。第二步,用玻璃棒进行搅拌,搅拌约1分钟47秒后,手指触碰烧杯底部已有微弱的温感。李博士解读:搅拌的目的就是为了让所有成分充分混合。暖贴发热原理是铁粉氧化反应。正常情况下,铁粉氧化是比较缓慢,但加入活性炭等成分,充分混合后能够加快这种氧化反应。第三步,分别搅拌7分钟、12分钟后,用温度计进行测量,前者温度已达到40℃左右,后者温度已达到58℃左右。李博士解读:这种发热过程是持续性的,发热温度是可以根据成分用量多少来调节,如果用量比较大,发热温度甚至能超过80℃。而目前,合格的暖贴类产品发热温度基本在50℃~60℃左右,但一些“三无”类产品就难以保证了,烫伤概率极高。■温馨提醒使用暖贴请记住以下5点:1.不能使用“三无产品”。2.不能直接贴在皮肤上。暖贴直接使用在皮肤上容易造成低温烫伤。3.不能在睡觉时使用。人在睡眠时感知能力下降,不易发觉被烫伤,而且睡觉时被子能起到保暖作用,使暖贴产生的热量不能散发出去,也更容易造成烫伤。4.特殊人群慎用。糖尿病患者、孕妇、小孩、皮肤热敏感度低者,请在使用时格外小心。因糖尿病患者经常会出现双腿麻木,下肢感应不灵敏的情况,用暖贴被烫伤不易被发现。而孩子和皮肤敏感者因皮肤较嫩,也容易被烫伤。5.不要把暖贴长时间贴在同一部位。这是一方面皮肤在温热状态下不透气,另一方面也防止皮肤被烫伤。相关的主题文章:
