What Are the Differences Between Thermos Cups with Different Layer?
There are many kinds of thermos cups produced on the market, and there are also many kinds of inner tanks, such as stainless steel, ceramic, purple sand, glass, etc., the insulation effect of different inner tanks is also different.
So what is the difference between them? Let me introduce you one by one.
Stainless steel vacuum flask is the most common vacuum flask on the market. The cost and price of this thermos cup are not high, and the insulation effect is good, and the price is high. The stainless steel liner used in the stainless steel vacuum flask is made of food grade 304 stainless steel, otherwise the stainless steel vacuum flask is unqualified. The inner pot of stainless steel vacuum flask contains iron element, which is one of the elements we need to take in every day. However, the stainless steel vacuum flask also has some disadvantages and is not suitable for making tea and coffee, because when the tea or coffee is soaked in water for a long time, the tea polyphenols, tannins and other substances contained in the tea and coffee will be leached from the water. Affect the use of the thermos cup.
Glass vacuum flask is also a common type of vacuum flask. Compared with other vacuum flasks, glass vacuum flasks are safer, because the glass liner of the glass vacuum flask is sintered from inorganic silicate, which has stable physical and chemical properties and is not easy to produce undesirable impurities during production and use. So it will not affect human health, and the double-layer glass tea cup has better heat insulation performance. But the glass vacuum flask also has one of the biggest shortcomings, that is, it is fragile. Glass is fragile, if you need to carry it for a long time, or if you need to take it outside, it can easily break.
Dark-red enameled vacuum flask is a less common vacuum flask. The thermos cup made of Dark-red enameled not only has the function of heat preservation, but also has the functions of health care and conditioning. The inner container of the Dark-red enameled vacuum flask is generally made of Dark-red enameled, and the outer shell is generally made of stainless steel, which is not easy to fall off. Dark-red enameled vacuum flask has many advantages, such as strong cold and hot adaptability, health and durability, and not hot. However, because the Dark-red enameled inner tank is more expensive, the cost of the Dark-red enameled thermos cup is also relatively high, resulting in a higher price of thermos cups sold by domestic brands in the market.
Ceramic vacuum flasks are now very rare in the market. Ceramic is a completely harmless material, so many kitchen utensils use this material such as ceramic kitchenware. Generally speaking, metal vacuum flasks and plastic vacuum flasks have some safety hazards, and long-term use may ingest bad metal substances. The ceramic vacuum flask is completely harmless and suitable for long-term use. However, ceramic vacuum flasks also have several disadvantages. First of all, ceramics are fragile items, not suitable for the elderly and children. Ceramic thermos cups are generally not airtight, so they are not suitable for outdoor use. At the same time, compared with stainless steel and glass insulated cups, the thermal insulation performance of ceramic insulated cups is relatively poor.
