Ceramic thermos cup
Ceramic cups and plastic cups are the healthiest compared to metal cups. Ceramic insulated cup inner liner is made of double-layer structure with excellent thermal insulation performance. Ceramic thermos cup is very durable, easy to clean, not easy to appear on the surface of dirt residue, generally do not need to use detergent can be cleaned, very time saving. Ceramic thermos cup is completely free of toxic substances, so you don't have to worry about ingesting a large number of harmful substances every day when you use it. The ceramic cup without colored glaze is better than the ordinary ceramic thermos cup, not only the material is safe, high temperature resistance, but also relatively good insulation effect, drinking hot water or drinking tea is a good choice. Whether it is drinking water or making tea or coffee, it is easier to clean, and it is not very hot, and it will not have a bad effect on health. However, the biggest disadvantage of ceramic thermos cup is that it feels heavy and easy to break.
Stainless steel thermos cup can not only keep heat, but also keep cold, and it is also convenient to use in daily life. Generally speaking, stainless steel thermos cup is food-grade 304 stainless steel, because the iron contained in stainless steel is also a trace element that we people need to ingest every day, which has a certain health effect on our human body. Stainless steel cups are alloy metal products, according to the use of different, the metal elements of this cup will be different, common metal elements include iron, silicon, carbon, aluminum, etc., these elements are other cups can not provide us. However, stainless steel thermos cups should not be used for tea and coffee. In addition, because stainless steel is a metal composite, the substances contained are more active substances, the production process will inevitably appear some impurities, these impurities will be some harm to the human body.
Glass thermos cup, healthy but not fall proof. The reason why the glass thermos cup is safer is because the glass is made of inorganic silicate sintering, which is a very stable substance, that is, the bad impurities contained in the production process will not leak out. And the glass is easy to clean, so the glass is the safest. However, glass tea has the disadvantage of being easily broken, so it is not convenient to use it with you.

Generally, the plastic thermos cups sold on the market can only have the function of insulation, and the function of insulation can only have a maximum of 2 to 3 hours, and the lower the room temperature, the faster the heat loss. Plastic thermos cups can also be insulated, but the insulation time of plastic cups, relative to stainless steel, ceramic thermos cups, the insulation effect is still far apart, not suitable for autumn and winter season.
