Due to the variety of types and materials of water cups on the market, many people do not know how to buy, if you are greedy for cheap, choose poor quality water cups, it may affect our health, everyone should pay attention.
In this issue, let's take a look, these 4 cups of hot water into the "poisonous water" out? Throw it away at home and don't use it again!
201, 202 industrial grade stainless steel
Stainless steel thermos cup is very popular, it has a good thermal insulation effect, and can drink hot water at any time.
It's just that not all stainless steel thermos cups are easy to use, we have to pay attention to the material inside, if it is a 201, 202 stainless steel thermos cup, I don't recommend you to buy it.
With the development of the times, this kind of thermos cup has been slowly eliminated, mainly because it does not meet the standard.
If you continue to use it, there may be "hot water in and poison water out", and there will be serious exceedances after hot water.
Many cheap thermos cups on the market have a similar situation, which contains a lot of heavy metals.
If you drink it for a long time, it will cause great harm to the body, so you should pay more attention and avoid drinking harmful water.
If you like to use a stainless steel thermos cup, it is recommended to choose 304 or 316, it meets the standard, and the heat preservation is also very durable, so when you buy a thermos cup, you must pay attention to the purchase.
glass
Glass is one of the cups commonly used in our lives, don't look at all glasses, it is also divided into multiple types,
It's just that most people ignore it, if you are greedy for cheap, choose an ordinary glass, this kind of cup is very impractical, when you put the kettle in it, there may be a risk of self-explosion, affecting your health!
Normally, a glass cup that can store a hot water bottle must be a borosilicate heat-resistant glass, which is very practical and 4 or 5 times more durable than ordinary cups.
When the borosilicate glass comes into contact with hot water, it expands very little, and it is very strong, and it will not break if it accidentally falls on the ground.
If you're not sure if your home glass is borosilicate, you can cool it in the refrigerator and pour boiling water.
If you want to do this experiment, you must ensure that it is safe to avoid unnecessary damage to the body.
Three plastic-free cups
Plastic cups are very commonly used cups in life, but many people don't understand, and the quality of plastic cups bought at home is very poor.
Especially the plastic cup of the Sanwu brand, it does not have any logo on it, and it is very harmful to the body with such a cup!
When a low-quality plastic cup comes into contact with hot water, it may release harmful substances, such as bisphenol A, which can enter the body and cause potential dangers, even if you buy cold water.
Especially when you buy something and give you a free plastic cup, the quality is relatively poor.
When we buy plastic cups, we must see if there is a mark at the bottom, there are usually numbers, the higher the number, the better the quality.
Disposable paper cups
Disposable paper cups are also commonly used items in life, usually when guests come to the house, due to the lack of cups, they will choose disposable paper cups to replace.
It's just that most people don't understand that this kind of disposable paper cup seems to be very humanely designed, but in fact there are great hidden dangers.
There was a similar incident on the Internet before, someone specifically investigated the disposable paper cup, but it was checked and disposed of fluorescent, this ingredient will be directly integrated into the water after encountering hot water, which will undoubtedly cause harm to the body.
It is recommended not to use disposable paper cups in life, and at the same time, do not directly fill hot water, and throw it away after using it once, and do not continue to use it after brushing, which is not right.
Write at the end:
I don't recommend you to fill these cups with hot water, it's not nonsense, it's all a lesson, have you learned?
