Experts point out that while people are paying attention to water quality, they also pay a lot of attention to drinking water tools. So, what kind of drinking cup is better?

First of all, from the perspective of the cup material, the glass is the safest, the enamel cup is also safer, the ceramic cup is better to use the color cup, and the plastic cup has more hidden dangers.

The glass is made of inorganic silicates and does not contain organic chemicals. So the glass is safest and easy to clean.

The enamel cup is made after dehydration at a high temperature of a few thousand degrees Celsius. It contains no harmful substances such as lead and is easy to carry and clean. The inner wall of the ceramic cup is usually coated with a layer of glaze. When the cup is filled with boiled water or acid and alkaline beverages At the time, some aluminum elements and other heavy metal elements in the glaze are easily precipitated into the liquid and endanger human health. Therefore, the use of ceramic cups is best to use the color cup, do not use the cup coated with colorful glaze.

Plastic cups have been loved by many people, especially children and adolescents, for their varied shapes, bright colors, and characteristics that are not afraid of being beaten. Experts are concerned about this phenomenon: Plastics are polymer chemical materials, often containing polypropylene. Or toxic chemicals such as PVC and polyvinyl chloride, which are easily dissolved in water when hot water or boiling water is put in plastic cups. Another reason why the use of plastic cups is not advocated is that plastic cups are prone to bacterial growth and are not easy to clean. The surface of the plastics looks smooth. Actually, its internal microscopic structure has many pores, and it is easy to hide dirt.

Secondly, for the "function cup" promoted by some businesses in the market today, consumers should recognize the principle of "functionality" and choose rationally.
