Everyone usually buys bowls, what style do you like to buy?
Plain ceramic bowl, or more imitation porcelain bowl?
How easy is it to get into trouble with imitation porcelain tableware?
Previously, the Shanghai Municipal Supervision Bureau randomly inspected a batch of children's tableware made of melamine (imitation porcelain), and of the 76 batches of products sampled, 9 batches of products were unqualified.
Among the unqualified products, 5 batches are melamine migration exceeding the standard!

Among the production enterprises involved, the well-known brand Mingchuang Excellent Products is prominently listed, and the others are small manufacturers' products.
A 1-year-old girl in Guiyang was diagnosed with lymphocytic leukemia, and the doctor believed that the cause was not excluded from the excessive formaldehyde of the imitation porcelain bowl fed.

Although it is still doubtful whether formaldehyde exceeding the standard can cause leukemia, the harm of formaldehyde exceeding the standard to the human body is real!
Our country's standard for melamine migration in melamine tableware is not more than 1.0mg/kg for children and 2.5mg/kg for adults.
In the list of exceeding the standard released by Shanghai Municipality, there are even products with a detection value of 5.0mg/kg, which seriously exceeds the standard!

Long-term excessive intake of melamine may affect the renal system, leading to diseases such as kidney stones.
Formaldehyde is more familiar to everyone, long-term living in an environment with formaldehyde pollution, it may cause respiratory chronic diseases, nasopharyngeal cancer, brain tumors and so on.
And these things, which are detected in directly infused tableware, are detected to exceed the standard, and for pregnant women and children who are less sensitive to chemicals and have lower immunity, this is no less than "poisoning"!
So why is tableware linked to formaldehyde and melamine?
This is mainly related to the raw materials of imitation porcelain tableware.
Imitation porcelain tableware, also known as "melamine tableware", is made of a material called melamine resin, and this material is a polymer obtained after the reaction of melamine and formaldehyde.

It is a very good polymer, lightly insulated, and very stable at below 120 ° C, so it is often used as a tableware.
However, if it is under high temperature, strong acid and other conditions, melamine will be released.
Quality imitation porcelain bowl, as long as the specification of use, even if a small amount of melamine will migrate, as long as it is within the standard line, it is still very safe for the human body!
But I am afraid that in some bad businesses, I will use cheaper urea-formaldehyde resin instead of melamine resin.
Urea-formaldehyde resin is prepared by the polycondensation reaction of urea and formaldehyde solutions catalyzed by alkali or acid, which will undergo hydrolysis and then release formaldehyde gas.
And the more moisture, the stronger the acidity, the higher the temperature, the more serious the degree of hydrolysis, so it is not suitable for food.
In fact, the current melamine tableware production process in the mainland has been very skilled, and the state's supervision of this is also relatively strict.
As long as you buy a regular brand of imitation porcelain bowls through formal channels, it can basically be said that it is not a big problem.
Just like the Mingchuang premium products found to have problems in Shanghai, they have long been detected and removed from the shelves during self-inspection before the inspection results of the Quality Supervision Bureau are announced.
However, if it is an imitation porcelain bowl bought in an irregular place such as a roadside stall, it is likely to buy a "defective product" of unqualified quality!
So if the family has bought an imitation porcelain bowl and can't remember the purchase channel, how to judge whether the quality is qualified or not?
The fungus believes that everyone has one or two imitation porcelain dishes in their homes.
So now that there is an accident, can the imitation porcelain dishes continue to be used?
Don't be nervous! Not all imitation porcelain bowls can't be used!
If you have bought an imitation porcelain bowl at home, you can identify the quality in the following way:
After inspection, the fungus recommends that the imitation porcelain bowl with poor quality do not hesitate to throw it directly!
Is the imitation porcelain bowl of qualified quality completely safe?
Of course not, how to use it correctly is also very important!
For a family, bacteria are not recommended to use only one material for dishes for a long time!
Although the imitation porcelain dishes are light and varied, the use of the scene is very limited.
The right thing to do is to use the right cutlery at the right time.
Bacteria also prepared for everyone the "use of common material tableware suggestions", you can refer to when using or purchasing:
These dishes that we use every day are things that everyone directly imports, and once an accident occurs, it is simply "precision poisoning"!
Therefore, bacteria often remind everyone that we must do a good job in the hygiene and purchase of household tableware.
Especially if there are pregnant women and babies in the family, the immunity is worse, the chance of being attacked by harmful substances is also higher, and the harm is greater.
Using more heart on tableware is to give the health of the family a little more protection!
