Everyone knows that our body needs water. The most scientific way of saying is that we need 8 cups of water per day. But for a long time, everyone has been concerned about how much water they drink every day, but has ignored the water container, the cups.
Different people like to use the different material cups, such as glass, plastic, ceramic, stainless steel, etc. Different materials, its advantages and disadvantages are also different. What kind of cup is better for drinking water?
Glass water cup
Among all materials, the glass material is relatively safe. Glass cups are usually made of soda lime glass, which are fired at a high temperature of over 600 degrees. Because of their relatively stable chemical composition, no harmful substances are generated during the production process. And normally the glass cup inner wall surface is smooth, easy to clean, bacteria and dirt are not easy to breed on the cup wall.
Pay attention: when first time use the glass cups, you should pour in a little hot water, shake it gently to preheat the glass, and then pour the hot water for use. Otherwise, the boiling water will maybe cause glass cup to burst.
Plastic water cup
Many people worry about the quality of plastic cups, but as long as you choose products related to brands that meet national quality inspection standards, it is actually safe.
Generally speaking, numbers are printed on the bottom of plastic cups, from 1 to 7. The higher the number, the higher the quality. The most common number are the number 5, PP material (polypropylene) and the number 7, PC material (polycarbonate).
The PP cup has good heat resistance, the melting point is as high as 167 degrees Celsius, and the chemical properties are relatively stable. It is the only plastic material that can be placed into microwave oven. The PC material water cup generally can only contain cold or warm water, because high temperature may cause this material to release toxic BPA.
Ceramic water cup
Usually their shape is beautiful, and patterns are diverse, and it also has a very broad market.
Ceramic cups are currently divided into three main categories:
1. Ceramic cup with no color glaze and colorless inner wall: The main component of the ceramic cup is clay, which will form a layer of glaze on the surface of the clay after high temperature calcination. Generally speaking, there are no harmful substances in this layer of glaze.
2. Ceramic cup with underglaze color: This type of cup is produced by paint first, and then calcined at high temperature. After this processing, the paint is stored under the glaze. Even if hot water is brewed, harmful substances will not leak out. Relatively speaking Health and Environmental Protection.
3. On-glaze ceramic cups: This kind of cups are painted on the glaze, and then baked to dry. It is easy to ooze out harmful substances during use and endanger human health, so it is not recommended.
For those who love to drink tea, most people prefer the Sand-fired pot. The Sand-fired pot is not glazed inside, nor outside, keeps tiny pores, has good air permeability, and has strong adsorption, which can effectively prevent the tea fragrance from losing.
No matter which material you choose, you must choose qualified products.
