Selection and maintenance of personal water cups. As we all know, the human body needs eight glasses of water a day to meet the body's metabolism, but do we use the right cup when we take in water? The following insulation factory shows you how to choose the right one.

Plastic cups: Plastic cups are popular among many people because of their versatile shape, bright colors, and fear of being beaten. They are very suitable for outdoor users and office workers. However, the plastic cup must be selected from the material of the food grade plastic. Because the plastic is a polymer chemical material, when the plastic cup is filled with hot water or boiling water, the polymer is easily precipitated and dissolved into the water, which is harmful to human health after drinking. And usually the bottom of the plastic product has a label on the material, the most common is the mineral water bottle, labeled PET1, or some will be written as PETE. This shows that the plastic bottle is made of "polyethylene terephthalate", can not be used to hold hot water, should not be used repeatedly, it will be recycled after drinking.

Insulation cups: Insulation cups are generally made of stainless steel, which is durable and rust-proof and corrosion-resistant. However, stainless steel cups are alloy products, which contain more heavy metal materials. If used improperly, these heavy metal materials are easily released and endanger health. Therefore, in daily use, be careful not to use acidic cups for acidic drinks, such as juice, coffee, carbonated drinks; not for long-term soy sauce, vinegar, soup, tea and so on. When washing stainless steel cups, do not use strong alkaline or strong oxidizing chemicals such as soda, bleaching powder, etc., these materials are also easy to chemically react with stainless steel.
