What kind of water bottle should I choose for drinking water?
Drinking water in a glass water bottle is the safest. While people pay attention to water quality, they also pay great attention to drinking water tools. So, what kind of water bottle should we choose? With people's attention to drinking water health and the strengthening of supervision by relevant state departments, the quality of drinking water products has improved. However, people have neglected the health and safety of water bottles used in daily life, and there are even misunderstandings. People should pay attention to the safety of water bottles.
First of all, from the point of view of water bottle material, glass water bottle is the safest, enamel cup is also relatively safe, ceramic cup is best to choose the natural color cup, plastic water bottle has more hidden dangers. Glass is sintered from inorganic silicates and does not contain organic chemicals. So glass water bottles are the safest and easy to clean. Enamel cup is made by high temperature enameling at thousands of degrees. It contains no harmful substances such as lead and is easy to carry and clean. The inner wall of ceramic cup is usually coated with glaze. When the cup is filled with boiling water or drinks with high acidity and alkalinity, some aluminium and other heavy metal elements in the glaze are easy to precipitate and dissolve into the liquid, which endangers human health. Therefore, the use of ceramic cups is best to choose colorless cups, do not choose glazed cups coated with colorful. Plastic water bottles are loved by many people, especially children and adolescents, because of their changeable shapes, bright colours and fearless of falling. Experts have expressed concern about this phenomenon. Plastics belong to macromolecule chemical materials and often contain toxic chemicals such as polypropylene or PVC polyvinyl chloride. When hot water or boiling water is filled in plastic water bottles, these toxic chemicals can easily precipitate into the water. Another reason why plastic water bottles are not recommended is that they are prone to bacteria and are not easy to clean. The surface of the plastic water bottle seems smooth. In fact, there are many holes in its internal micro-structure, which makes it easy to hide dirt. If you choose plastic water bottles, you must choose water bottles made of food grade plastics that meet the national standards.
