When we want to choose a cup that suits us, we will find a variety of cups: glass, enamel cup, ceramic cup, plastic cup, stainless steel cup, iron cup, aluminum cup, paper cup... let People are overwhelmed and unable to start, especially those cups with bright colors and unique shapes are more eye-catching, picking them up and picking them up.
Colorful cups are very flattering, but in fact, there are huge hidden dangers in those bright pigments. When the cups are filled with boiling water or acidic or alkaline beverages, lead and other toxic heavy metal elements in these pigments. It is easy to dissolve in liquids, and people who drink liquids with chemicals can cause harm to the human body. Plastics are often added with plasticizers, which contain some toxic chemicals. When using hot water or boiling water in plastic cups, toxic chemicals are easily diluted into water, and there are many gaps in the internal microstructure of plastics. Contaminated. Therefore, experts reminded that when purchasing plastic cups, it is necessary to choose a cup made of food grade plastics that meets national standards.
In addition, there is a relatively large team in the water cup family, which is the "magnetized cup" and "energy cup" promoted by the merchants. Medical reports at home and abroad do claim that magnetized water is beneficial to the health of the human body, but not all magnetized water is beneficial to human health. Only the magnetized water of the negative electrode can improve the physiological function of the human body and play a role of health care, and the magnetized water of the positive electrode should not be drunk. Most of the magnetized cups we see on the market use ordinary magnets, and the positive and negative poles are not divided. Therefore, consumers should carefully identify when selecting a magnetized cup, and purchase a magnetized cup made of a single-pole magnetic piece (negative electrode). In principle, the "energy cup" can also improve the function of the human body and play a role in health care. However, many manufacturers of "energy cups" on the market today have not verified the physiological effects of this function, exaggerating the role of the "energy cup", and some even claim to be able to cure all diseases. Experts remind consumers that when purchasing an "energy cup" with health benefits, they should recognize the legal certification given by the relevant departments and must not blindly follow.
Experts also advocate the use of enamel cups, because enamel cups are made after thousands of degrees Celsius high temperature, and do not contain harmful substances such as lead, you can use them with confidence.
However, the glass should be preferred when drinking water. Don't think that the glass is just transparent. In all the cups, the glass is the healthiest. The glass contains no organic chemicals. When people drink glass or other drinks, don't worry that the chemicals will be drunk into the stomach, and the glass surface is smooth and easy to clean, so people drink glass with water. Healthy and safe. Due to the nature of the glass material, when the temperature of the liquid in the cup is too high or too low, the traditional glass tends to be too high or too low, so that the user can not hold it. If it is not careful, it may even be caused by the hand. Damage, but the new double-layer glass solves this problem by adopting a two-layer structure, which effectively reduces the thermal conductivity of the cup, improves the comfort of the product, and enhances the insulation effect of the glass. In addition to its user-friendly design, double-layer glass also has very good aesthetic value. The transparent texture combined with the two-layer structure almost sublimates the tea into a dynamic artistic behavior. Especially in the case of tea, the bright color of the tea soup, the tenderness and softness of the tea leaves, the tea leaves moving up and down throughout the brewing process, and the leaves gradually stretch, through the unique cup body, bringing the user a kind Very tasteful visual enjoyment.
After reading it, is there a different understanding of the double-layer glass.
