why don’t you use plastic cups when drinking water
In addition to the release of some chemicals after heating, plastic cups are also very easy to breed bacteria. Although the plastic surface looks smooth, there are actually many gaps, which are easy to hide dirt. In the office, people only wash the cups with clean water, and the cups cannot be thoroughly cleaned and disinfected. Experts suggest that it is better to use stainless steel cups or glasses in the office, and wash them every day. It is better to use detergent and wash them with hot water.
In addition, the cup will absorb more dust, bacteria and germs under the influence of static electricity from computers and chassis, which will affect health for a long time. For this reason, Lu Jianguo, director of the comprehensive inspection department of the national household appliance quality supervision and inspection center of the China Home Appliance Research Institute, suggested that it is best to fit a lid on the cup and keep it away from computers and other appliances. At ordinary times, it is also necessary to maintain indoor air circulation, open windows and ventilate, so that dust can go with the wind.
Glass should be the first choice for drinking water. Don’t think that the glass is just transparent and beautiful. Among all the materials, the glass is the healthiest.
The glass does not contain organic chemicals during the firing process. When people drink water or other drinks with glass, they don’t have to worry about chemicals being drunk into their stomach. Moreover, the glass surface is smooth, easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, it is the healthiest and safest for people to drink water with glass.
In addition, experts also advocate the use of enamel cups, because enamel cups are made after thousands of degrees of high temperature enameling. They do not contain harmful substances such as lead, and can be used with confidence.
Colorful ceramic cups are very popular, but in fact, there are huge hidden dangers in those bright colors. In particular, the inner wall is coated with glaze. When the cup is filled with boiling water or drinks with high acidity and alkalinity, the toxic heavy metal elements such as lead in these pigments are easy to dissolve in the liquid. When people drink liquids with chemical substances, they will cause harm to human bodies. Plasticizers are often added to plastics, which contain some toxic chemicals. When hot water or boiling water is filled in plastic cups, the toxic chemicals are easily diluted into water, and the internal microstructure of plastics has many pores, in which dirt is hidden. If it is not cleaned, bacteria will easily breed. Therefore, experts remind that when shopping for plastic cups, we must choose drinking cups made of edible grade plastics that meet national standards.
