There are three common types of thermos cup liner in the early market: stainless steel liner, glass liner and purple sand ceramic liner. With the passage of time, most popular thermos cups on the market are made of stainless steel, because the stainless steel liner is safe and durable, and the thermal insulation performance of stainless steel thermos cups is also relatively good. For example, glass liner and ceramic liner are eliminated mainly because they are not resistant to falling and fragile. Another point is that the iron element contained in stainless steel is also a trace element that we people need to ingest every day.
For the glass liner of the thermos cup, although it is healthy, it does not prevent falling. The advantage is that the glass liner is safer, because the glass is sintered from inorganic silicate, which is a very stable material, and the glass cup 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 cup wall, so it is safer to use the glass liner. The disadvantage is that the glass is easy to break, so it is inconvenient to carry with you. It is only suitable for home use.
The ceramic insulation cup is relatively heavy, and it will not be broken in the ceramic insulation cup industry, because it is basically harmful to the metal insulation Cup after long-term use.
There are two kinds of stainless steel liner of thermos cup. 316 edible stainless steel is used for high-grade cups and 304 edible stainless steel is used for medium-grade cups, which is also a low standard stipulated by the state. Stainless steel liner is safe and harmless only within the scope of national standards. It can not only keep warm, but also keep cold. It is also very convenient to use in daily life.
Through the above comparison, we can clearly know why the stainless steel liner of the thermos cup finally occupied the market. For the stainless steel liner of the thermos cup, the stainless steel material is generally 304 edible stainless steel. There are also some high-grade cups with special requirements that use 316 edible stainless steel. Both types of stainless steel meet the requirements of national standards. Chaolang stainless steel thermos cup can customize 316 stainless steel liner or 304 stainless steel liner according to customer needs to meet all customer needs.
