  What harm will heavy metals seriously exceed the standard? Can make the child grow slowly; Zinc, calcium and iron deficiency; Hemoglobin synthesis disorder and low immunity; Learning difficulties and inattention; Mental decline or physical growth retardation and other symptoms; Do not use these thermos cups for children Mothers who often pick things for their children should also find that there is a great difference in the price of thermos cups on the market
Some of the expensive ones are up to thousands of yuan, and the cheap ones even include mail as long as a few yuan Although the more expensive the goods, the better, there is no need for children to pursue high-grade things
, But it's really not recommended that you give your children too cheap thermos cups, especially those that cost 20 or 30 yuan each, in small shops and supermarkets; Three no products & rdquo Although this kind of thermos cup is cheap, it has many potential safety hazards
Let's say it briefly: ▍ excessive heavy metals: This mainly refers to the inner container of the thermos cup
Qualified thermos cups are made of food grade stainless steel & mdash& mdash; 304 and 316 (in addition, compared with 304, 316 is lighter, more resistant to high temperature and corrosion, but the cost is also higher
If possible, I suggest you give your children 316 steel mugs
) No matter what kind of stainless steel, there are three kinds of metals: nickel, chromium and manganese Manganese should be less than 2%, chromium content should not exceed 18%, and nickel content should be 8% ~ 12% No matter what metal it is, once it exceeds the standard, it will hurt the child's body Manganese exceeds the standard Generally speaking, the metal exceeding the standard is caused by some businesses replacing other materials with manganese in order to save costs It can reduce immunity and lead to loss of appetite
In severe cases, it may affect intelligence and even increase the risk of cancer and Parkinson's disease A qualified thermos cup can keep warm for at least 6-8 hours It is mainly insulated by the vacuum layer between the inner tank and the outer wall For example, some thermos cups with poor vacuum pumping technology and unreasonable design may be similar to ordinary water cups, which need not be considered How to choose a qualified thermos cup for children & radic; Liner material: 304, 316 stainless steel The inner liner of the thermos cup is made of stainless steel, and different materials also have a great impact on human health
The main materials of stainless steel are 201, 304 and 316 201 the corrosivity of such materials is not enough, the content of manganese is too high, and excessive intake will be harmful to human body 304 this kind of material has good processability and corrosion resistance, and is recognized as food grade stainless steel by the state 316 quality is greater than 304, with more metal molybdenum, which can increase corrosion resistance; But such prices are relatively high Tightness: the water outlet is tight For young children, the sealing performance of the thermos cup is very important, otherwise it is easy to burn
The gasket material of the inferior thermal insulation cup has poor sealing effect and poor thermal insulation process, which has potential safety hazards
It is not only easy to scald the baby, but also affect the thermal insulation effect Therefore, we must choose a close thermos cup at the water outlet to provide a guarantee for the baby's safety & radic; Thermal insulation: it's not hot outside Parents can pour hot water into the cup and observe the heat on the wall and bottom of the cup over a period of time
If it starts to become warm or even hot, it means that the heat preservation of the cup is general, and the baby may be scalded
A good thermos cup should not be hot when touched outside If you are interested, please search: Shanghai silede Industrial Co
