Before and after the festival, there was widespread news of manganese melted and toxic with the use of high-manganese steel kettles to boil water, which generated a considerable response from consumers and merchants in my city. The use of high-manganese steel canteens to burn water is either toxic or non-toxic, and journalists have learned from visits to experts in our city's three steel departments, chief inspectors, hospitals, etc. That the term “high-manganese steel” canteens burn manganese. And look..
The stainless steel pot is now almost essential to life, not only for many families but also for hotels, hotels, teahouses, etc。
On 17 march, the jiangsu provincial directorate of quality monitoring issued a “results of a small household electric pump”. Two days later, in a tv station in guangdong province, a doctoral student stated that food containers made of “heated manganese steel” would cause “manganese” to melt during heating, and said that a long-term overdose of manganese would cause damage to the human body. After 20 march, in a number of micro-intelligence and online media, is there a scientific basis for the statement that the stainless steel kettle “too terrible” “drinking” “drinking” to “cancer” to “drink” to “drinking” to “high manganese steel” to “toxic kettle”
Consumers
It's a new wave
With the spread of this statement, a number of consumer fears have arisen。
"i saw the news of the poison kettle in the community of friends, and found that the pictures were very similar to the one used in my house, so i was busy opening the inside of the kettle, and i did not really find the label "304 stainless steel," which was too scary, so i decided to replace it immediately." on 22 march, ms. Wong, who lived in a high-rock community, told journalists about this at the municipal wal-mart supermarket when she selected a water kettle。
Mr. Chen, who lives in the new village of the lidong park, is relatively calm. He said: “although it is not particularly true to believe in the information on twitter, since there are health-impaired claims, it is true that the electric kettle in the home has taken years to replace it.” this time, when mr. Chen went to the mall to buy a kettle, he specifically consulted the waiter. Finally, he spent $159 on an electric kettle marked “food-grade 304 stainless steel”。
Business
Highlight the "health" selling point
From 30 to 31 march, journalists visited the city's wal-mart, da yunfa, xinhuadu, many large supermarkets and a number of water kettle stores, and found that most of the electric kettles placed on containers were labelled “304 stainless steel”。
In many double-garden shopping malls, journalists consulted the purchaser with the electric kettle. She immediately recommended a 199-dollar “304 stainless steel” kettle, and, on the basis of the “venomous kettle” information circulated on twitter, an analysis was made of the merits of the “high-manganese steel” and “304 stainless steel” kettles。
From 21 to 27 march, she sold, on average, more than 10 “304 stainless steel” electric kettles a day, and around 8 daily after 28 days. In this supermarket, journalists have seen containers with branded electric kettles with prices ranging from $49 to $100, some with the mark “304 stainless steel” on their shell or inside their guts, others with the label “304 stainless steel” on them, or without any marking. According to the requisitioner, those that were not marked were old-fashioned and were actually made of “304 stainless steel”. In supermarkets such as wal-mart, da-roufa, the purchasers also used “health” as a factor to select consumers of the electric kettles and sell “304 stainless steel” pots。
In some water kettle stores, “old for new” sales are promoted. At an electronics store near east new fifth street on east east east street, a promotion was made to “purchase new pots of up to $200, for old pots of up to $20, for new pots of over $200 and for old pots of up to $30”. The shopkeeper, ms. Lin, told reporters that she had changed over 20 old kettles over the past few days, and that the old kettles had been sold to the scavengers. “i am doing this `old-for-new' campaign from everyone’s health perspective, by promoting the pots in the store。
Three steel workers
The manganese melting point is nearly 1,300°c
Is it true that the “heavy manganese steel” kettles burn water, which can lead to manganese distillation? Is it really poison to drink this water for a long time? On 5 april, the senior engineer of the technical centre of the three steel group, the dragon fellowship army, made it clear in an interview with the press that it did not agree with this statement。
The dragon fellowship told journalists that concerns about the health risks of burning water in high-manganese steel canteens were mainly due to allegations that manganese would be released during heating. However, in the case of high-manganese steel being used as a boiler to boil water, manganese is not generally produced. Since the melting point of the manganese element is generally at more than 1,200 degrees celsius, if manganese is added to the steel, the manganese alloy compound is created, thus greatly increasing its strength and resilience, and its melting point rises to more than 1,300 degrees celsius, but the temperature of burning water with an electric kettle will not be so high, so, from the point of melting, since the manganese element in the manganese steel can withstand such high temperatures, it is difficult to discern at more than 100 degrees celsius。
Doctor
It's a misunderstanding about manganese poisoning
According to dr. Dundemin, doctor at the first hospital in the city, the concern about the high-manganese steel kettle is also reflected in a misperception of manganese poisoning. The main cause of manganese poisoning was human ingestion of oxides containing excess manganese. When water is boiled with high-manganese steel canteens, manganese-containing oxidizers are generally not released, and even if manganese is distilled through boiled water, the content is very small, less than in articles such as food and piped water, and therefore not harmful to humans。
According to dundemin, a modest quantity of manganese would also be beneficial to the human body, but excessive intake of manganese would be harmful to the human body. Harmful conditions occur mainly when manganese oxide is overdosed through the respiratory system. Such oxides, when inhaled into the human body, cause acute damage to the human respiratory system; prolonged ingestion can damage the human nervous system. The amount of manganese ingestion through the digestive system is small and is not excessive and harmless. However, manganese poisoning occurs if minerals dust and gases containing manganese oxide are inhaled for long periods. For example, smoke generated during welding, containing manganese oxides, which cannot be inhaled for long periods, should be protected by masks。
Quality control
Buy a kettle to recognize 3c authentication
Journalists also interviewed a number of specialists from san ming college and san ming institute of vocational technology on the health implications of burning water in high-manganese steel pots. The view was expressed that there was no harm to the human body as long as the water was boiled with a high-manganese steel kettle meeting the criteria, and it was produced without manganese-containing oxide gas。
So, what kind of high-manganese steel kettle does it meet the standard? Quality section of the municipal quality monitoring and inspection board, zhang chang, said that, as required by the regulations for the management of compulsory product certification issued jointly by the general directorate for quality control and quarantine and the national board for the accreditation and recognition of products, electric kettle products were subject to 3c certification. Therefore, zhang changbing recommends that consumers, when purchasing electric kettles, look carefully at whether the kettles have a 3c-certified logo and, for safety reasons, that consumers also have access to the website of the general directorate of quality inspection to check whether the producers of the canteens have obtained 3c certification。
It is understood that the 3c certification is fully known as the “compulsory product certification system”, which is a product qualification system implemented by the government to protect the safety and security of consumers, strengthen product quality management and comply with laws and regulations.
