In today's vigorous promotion of healthy drinking water in the era, the Cup has become more and more people's preferred cups. However, as a result of the Thermos cup materials, a wide range of brands, many people in the selection of the Thermos flask, the best of what materials still exist doubts. What kind of cup material is good? Today, I would like to introduce you to the stainless steel mug liner materials related knowledge.
Ceramic Mug
Ceramic liner in the stainless steel mug industry is not a lot of ceramic is completely harmless, it will not be like metal cups, plastic cups, long term use will have the possibility of ingesting harmful substances such as metal, but because fragile, still very heavy, and relatively short heat preservation time. So basically eliminated.
304 Edible grade stainless steel liner
Stainless steel should be food grade 304 stainless steel, in the national standard within the scope is safe and harmless. Because stainless steel contains iron elements, but also we people need to ingest every day trace elements. It can not only heat preservation, but also cold, in the daily use is also very convenient. But stainless steel mug is not suitable for tea and coffee. Make tea with a Thermos cup for long time in high temperature, constant temperature water, can cause a large amount of vitamin in tea is destroyed, and aromatic oil will evaporate, tannic acid, theophylline a large number of leaching, not only reduce the nutritional value of tea, but also make tea juice no fragrance, tea taste bitter, harmful substances increased, loss of tea due to health functions.
Glass Liner
Glass liner, although healthy but not to fall. The reason the glass liner is safer, because the glass is a kind of inorganic silicate sintering, is a very stable substance, and glass in the firing does not contain organic chemicals, glass surface is smooth, easy to clean, bacteria and dirt is not easy to breed in the cup wall, so the glass gall bladder is the safest. But the glass has the fragile flaw, therefore uses the carry-on to carry is not convenient, only is suitable for the home use.
