Plastic cups are widely used as materials, especially for making bottles and space cups. In recent years, the bottle has been controversial because of its bisphenol A. Experts pointed out that in theory, as long as bisphenol A is converted into plastic structure in the process of making plastic cups, it means that the products have no bisphenol A, let alone the release. However, if a small amount of BPA is not converted into a plastic cup structure, it may be released into food or drink. The bisphenol A remained in the plastic cup. The higher the temperature, the more the release and the faster the speed. Therefore, hot water should not be used in PC bottles. If there is any breakage or breakage in the container, it is recommended to stop using, because if there are tiny pits on the surface of plastic products, it is easy to hide bacteria. Avoid repeated use of aging plastic appliances.
In addition to being heated by chemicals, plastic cups are also prone to produce bacteria. Although the surface of the plastic looks smooth, there are actually many gaps, so it is easy to hide dirt. In the office, most people wash the cups only with clean water, the cups can not be thoroughly cleaned and disinfected. Experts recommend that the office should be cleaned with stainless steel or glass every day, preferably with detergent and hot water.
In addition, the cup by the computer, chassis and other electrostatic impact, will absorb more dust, bacteria, bacteria, over time will affect health. Therefore, Lu Jianguo, director of the Comprehensive Inspection Department of the National Household Appliances Quality Supervision and Inspection Center of China Household Appliances Research Institute, suggests that it is better to give cups a lid, and not close to computers and other electrical appliances, and should also maintain indoor air circulation, open windows and ventilation, so that dust can go with the wind.
Drinking glasses should be glass. Do not think that glass is only transparent and good. In all cups of material, glass is the healthiest.
Glasses do not contain organic chemicals in the process of firing. When people drink water or other drinks with glass, they do not have to worry about chemical substances being drunk into the stomach, and the glass surface is smooth, easy to clean, bacteria and dirt are not easy to breed on the wall of the glass, so drinking water with glass is the healthiest and safest. All.
In addition, experts also advocate the use of enamel cups, because the enamel cup is made after thousands of degrees of high temperature enameling, without lead and other harmful substances, can be safely used.
Colorful ceramic cups are delightful, but in fact there are huge hidden dangers in bright colors, especially glazed interiors. When the cups are filled with boiled water or acidic or alkaline drinks, toxic heavy metals such as lead in these paints dissolve easily in liquids and people drink chemicals. The liquid will cause harm to the human body. Plastics often contain plasticizers, which contain some toxic chemicals, hot water or boiling water with plastic cups, toxic chemicals are easy to dilute into the water, and the plastic internal microstructure has many pores, which hide dirt, cleaning will be easy to breed bacteria. Therefore, experts warn that when choosing plastic cups, we must choose the food-grade plastic cups that meet the national standards.
