Cups are the most common daily necessities, but the more common they are, the easier it is for people to pick the eye, because there are so many types.
Choosing a cup is not a trivial matter, because it will affect your health.
Don’t drink coffee with metal cups. Metal cups, such as stainless steel, are more expensive than ceramic cups.
The metal elements contained in the enamel cup are usually relatively stable, but they may dissolve in an acidic environment, which is not safe for drinking acid drinks such as coffee and orange juice.
Disposable paper cups or disposable cartons with hidden potential carcinogens just look hygienic and convenient. In fact, the product qualification rate cannot be judged, whether it is clean and hygienic, and it cannot be identified with the naked eye.
From the perspective of environmental protection, it should still be possible to use less disposable paper cups.
Some paper cup manufacturers add a lot of fluorescent whitening agents to make the cup look whiter.
It is this fluorescent substance that can cause cells to mutate and become a potential carcinogen once they enter the human body. Second, those unqualified paper cups are generally soft and easily deformed when poured into water, and some paper cups have poor sealing.
This is a typical inferior paper cup.
Plastic cups are the easiest to hide dirt. Plastic cups should also be an unwelcome one.
Because plasticizers are often added to plastics, which contain some toxic chemicals. When hot water or boiling water is filled with plastic cups, toxic chemicals can be easily replaced with water, and there are many alternatives to the internal microstructure of plastics.The dirt is hidden in it, and it is easy to breed bacteria if it is not cleaned.
Therefore, when choosing a plastic cup, you must choose a water cup made of food-grade plastic that meets national standards.
Use multicolored cups, beware of heavy metal poisoning cups is attractive, but it is best not to use.
Because there are huge hidden dangers in those bright pigments, especially the inner wall is coated with glaze. When the cup is filled with boiling water or acid, high alkaline beverages, the toxic heavy metal elements such as lead in these pigments are easily dissolved in the liquid.In China, people drink liquids with chemical substances, which will cause harm to the human body.
The healthiest material-glass. Of all the glass materials, the glass is the healthiest.
The glass does not contain organic chemicals during the firing process. When someone uses a glass to drink water or other beverages, there is no need to worry about the chemicals being drunk into the belly, and the glass surface is smooth and easy to clean. Bacteria andDirt is not easy to grow on the wall of the cup, so someone drinking from a glass is the healthiest and safest.
However, although the glass does not contain chemicals and is easy to clean, the glass material itself is very strong, which can easily cause users to accidentally burn themselves. If the water temperature is too high, it may cause the glass to burst, and it is necessary to avoid containing hot water as much as possible.
Colorless glazed ceramic cups are both thermal insulation and safe to drink. The ceramic glazed ceramic cups are preferred, especially the inner walls should be colorless.
The material is almost safe, can withstand high temperatures, and has a relatively better insulation effect. Drinking hot water or tea is a good choice.
