The weather is getting hotter and hotter. Are many friends like me? Their daily intake of water is gradually increasing, so a water bottle is very important!
I usually use plastic water cups to drink water in the office, but many people around me think that plastic water cups are unhealthy because they may be scalded under high temperatures or emit some substances that are not harmful to our human body.
Some people think that stainless steel cups are prone to scale and will affect our daily lives. So which one is safer, stainless steel cups or plastic cups?
Today I’m going to talk to you about this topic and see if you bought the right cup.
What are the problems with thermos cups?
When you watch the news, you will definitely see CCTV news reports on the quality issues of thermos cups. As a water cup that will definitely be used in daily life, we also need to pay attention to the thermos cup when choosing it.
01 Thermos cup produced using industrial grade stainless steel
The thermos cups criticized by CCTV are mainly divided into two types. The first is industrial grade stainless steel, the general models are 201 and 202; the second is video grade stainless steel, the general models are 304 and 316.
The reason why this type of thermos cup is called a “poisonous water cup” is because it is unstable during the production process and can easily produce harmful effects on our body.
02 Thermos cup that does not meet national standards
Qualified thermos cups need to pass national quality inspection, but many thermos cups produced by small workshops have not passed national quality inspection, and they also use non-national standard stainless steel materials, so they will affect daily life and even endanger your health. .
What are the problems with plastic cups?
I believe many people have begun to fear thermos cups after seeing this. So are plastic cups completely trustworthy?
Plastic cups are made of many kinds of materials, and it does not mean that all plastic cups can hold hot water.
If the water cup you buy is made of PC material, it is not recommended that you usually use it to hold hot water; generally, plastic materials of grade 5 or above in this picture can hold hot water. So should you choose a thermos cup or a plastic cup?
Both plastic cups and stainless steel cups have certain drawbacks, so which cup is worth buying?
Although both types of cups have their own disadvantages, the safer one is the stainless steel thermos cup.
Using a thermos cup can also play a role in heat preservation. Let’s talk to you about how to choose a thermos cup.
01 Don’t buy three-no products
When choosing to buy a thermos cup, do not choose a three-no product. It is best to choose a thermos cup produced by a regular manufacturer. If there is no exact mark on the cup, it is best not to buy it. Such a water cup will have harmful effects on our body after use. Health effects.
The thermos cups are only marked with 304 (L) and 316 (L), so you can buy such thermos cups.
As long as these logos are clearly marked on the thermos cup, it proves that it is a regular manufacturer and has passed national quality inspection, so you can use it with confidence.
02 Don’t buy a smart thermos cup
There are various kinds of thermos cups on the market now, and many of them are branded as black technology and can cost hundreds of dollars. In fact, such thermos cups are not much different from ordinary thermos cups.
Smart thermos cups are actually “IQ taxes”. When you buy a thermos cup, you only need to buy one produced by a regular manufacturer, and the price is only a few dozen yuan.
Don’t be confused by some fancy gimmicks on the Internet. After all, the biggest use of a thermos cup is to keep it warm and hold water. Don’t think that expensive water cups have other functions.
