Plastic cup is a kind of material that is used a lot, especially to make milk bottle, space cup and so on. In recent years, milk bottles have been controversial because they contain bisphenol A. In theory, as long as bisphenol A is 100 percent converted into plastic in the process of making plastic cups, the experts say, the product has no bisphenol A, much less release. However, if A small amount of bisphenol A does not convert into A plastic cup, it may be released into food or drink. The remaining bisphenol A in the plastic cup, the higher the temperature, the more the release, the faster the speed. Therefore, no hot water should be served on a PC. If there is any fall or breakage of the container, it is recommended to stop using it, as the surface of the plastic product is easy to hide if there is a small pit grain. Avoid repeated use of aging plastic appliances.
In addition to being heated, plastic cups can release chemicals and bacteria. Although the plastic surface may seem smooth, there are many gaps and easy to be polluted. In the office, the glass is mostly washed with water, the cup is not thoroughly cleaned and disinfected. Experts suggest that the office should be cleansed with a stainless steel cup or glass every day, preferably using a detergent and rinsing with hot water.
In addition, the cup is affected by static electricity such as computer, machine box, will absorb more dust, bacterium, bacterium, long will affect health. To this end, the Chinese electrical appliances research institute national quality supervision and inspection center of household electrical appliances jian-guo lu, director of the comprehensive inspection department advice, had better give the cup with a lid, and don't get close to the appliances such as computer, at ordinary times should also maintain indoor air circulation, open a window ventilated, let dust gone.
Glass should be the first choice. Don't think that glass is just plain, but in all the material cups, the glass is the healthiest.
The glass in the process of firing containing no organic chemicals, when people use a glass of water or other drinks, don't have to worry about chemicals can be drink into the belly, and the glass surface is smooth, easy to clean, propagation of bacteria and dirt is not easy in the glass, so people use a glass of water is the most healthy and safe.
In addition, the expert also advocates using enamel cup, because enamel cup is made after the high temperature of the high temperature, do not contain lead and other harmful substances, can be used safely.
Colorful ceramic cup is very attractive, but in fact hiding in the bright paint that huge hidden trouble, especially the walls painted with glaze, high when the cup is filled into the boiling water, acid or alkaline beverage, and toxic heavy metal elements such as lead in the paint is easy to dissolve in the liquid, people drink into the chemical liquid, will cause a harm to human body. And often add plastic plasticizer, which contain some poisonous chemicals, plastic cup of hot water or hot water, poisonous chemicals that can easily be diluted into the water, and plastic internal microscopic structure there are a lot of pore, which hides dirt, cleaning not net will be easy to breed bacteria. So, experts remind, when choosing plastic cup, must choose the water cup that accords with national standard edible grade plastic.
