In today's green and environmental protection, healthy drinking water has spread to all families. Water purifiers, water pumps and other equipment are only for healthy drinking water, but as a portable hot cold thermos, how can we drink healthy water? Healthy drinking water of thermos cup mainly depends on the material of inner container of thermos cup, because thermos direct drink flasks with different inner containers have different effects on water quality.
Ceramic liner thermos cups-Ceramic liners are not many in the stainless steel thermos flask 500ml industry. Ceramics are completely harmless. It will not ingest harmful substances such as metals after long-term use like metal cups and plastic cups. However, because ceramics are fragile and heavy, and the heat preservation time is relatively short. So it was basically eliminated.
304 edible stainless steel inner liner large thermos flask.304 stainless steel is safe and harmless within the standard range stipulated by the state. Because the iron contained in stainless steel is also a trace element that we need to ingest every day. It can not only keep warm, but also keep cold, and it is very convenient to use in daily life. However, the stainless steel hydro flask sport cap should not be used for making tea and coffee for too long, because the tea leaves will be soaked in high-temperature and constant-temperature water for a long time, which will lead to the destruction of a large number of vitamins in the tea, the volatilization of aromatic oil and the leaching of tannic acid and theophylline, which will not only reduce the nutritional value of tea, but also make the tea juice tasteless, bitter in taste and increase in harmful substances, thus losing its proper health care function.
Glass liner-glass liner, although healthy, is not anti-falling. The reason why the glass liner is safer is that the glass is sintered from inorganic silicates, which is a very stable substance, and the glass does not contain organic chemicals during firing. The glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass thermos flask wall, so it is safe to use the glass liner. However, glass is fragile, so it is not convenient to carry around and only suitable for home use.
The thermos cup with dark-red enameled liner not only has the basic function of stainless steel small thermos flask, but also can make tea, which has the functions of keeping healthy and conditioning. For dark-red enameled thermos cups produced by regular manufacturers, the inner liner is generally made of authentic pure natural dark-red enameled mud, and the outer shell is usually made of stainless steel with anti-falling and anti-cracking properties. In addition, the dark-red enameled thermos flask for tea has strong adaptability to sudden changes in cold and hot, and it will not burst due to sudden changes in temperature after being injected with boiling water, and the dark-red enameled thermos flask 1 litre has slow heat transfer and is not hot.
There are also plastic thermos cups. Usually, the plastic thermos cups sold in the market can only have the function of heat insulation, which can only last for 2 to 3 hours at most. The lower the room temperature, the faster the heat loss. Plastic thermos flask online can also keep warm, but compared with stainless steel and ceramic thermos cups, the heat preservation time of plastic thermos cups is far behind, so it is not suitable for use in autumn and winter. According to experts, long-term use of plastic cups may lead to cancer.
