How to choose thermos bottle?
What kind of thermos bottle is good?
1. Thermal insulation performance. As we all know, the main function of the thermos bottle is heat preservation. The heat preservation function of the thermos bottle mainly refers to its inner tank, which is also an important indicator to identify the quality of the thermos bottle. We can fill the thermos bottle with hot water, and then turn the thermos bottle cover clockwise. After about 2-3 minutes, touch the outside of the thermos bottle by hand. If there is a warm feeling, it means that the heat preservation performance of this thermos bottle is not very good. At present, the inner liner of the thermos bottle with better heat preservation performance is treated with copper plating. We all know that copper has strong high temperature resistance and corrosion resistance, and the inner liner of the thermos bottle with this treatment has better heat preservation.
2. Tightness. The tightness of the thermos bottle is also very important. When selecting the thermos bottle, we can fill the thermos bottle with water, then tighten the cover, and then turn the cup upside down for about 10 minutes, and we can shake it vigorously. If there is no leakage of water, the sealing of the thermos bottle is good. The sealing property of the thermos bottle is related to the thermos bottle cover. Now, the thermos bottle cover designed better in the market uses food grade silica gel. This material is safe and non-toxic, with less peculiar smell and good sealing property. It can be closely combined with the thermos bottle body. And the thermos bottle with poor sealing adopts the cup cover made of plastic material, which has poor sealing.
3. Whether it's healthy. It is very important to know whether the thermos bottle is healthy. We can judge whether it is healthy or not by smelling. If the cup smells big or has a strong smell, then such thermos bottle usually contains excessive added substances, which will cause great harm to the body if it is used for a long time. The health standard of the heat preservation cup is mainly related to its material. Now most of the materials of the thermos bottle are made of stainless steel. The high-quality thermos bottle is made of 304 stainless steel. This material is of good quality, corrosion-resistant and rust proof, with more bright color, and the health is guaranteed when it is used. Some of the poor thermos bottles are made of 201 stainless steel, which has the problem of manganese content exceeding the standard, which will lead to unstable steel performance, easy to rust and corrosion, and the problem of metal content exceeding the standard in human body easily occurs in long-term contact with oral cavity.
4. Check the quality of the thermos bottle and whether the production is up to the standard. Finally, we should not forget to look at the quality of the thermos bottle, mainly the appearance. A good thermos bottle should have a smooth appearance, no impurities, obvious color and beautiful body. In addition, it is necessary to check whether there are joint marks from the body to the bottom of the thermos bottle. Now, the body and the bottom of the high-quality thermos bottle are integrated. Such a thermos bottle has a long service life, and because of the integrated structure, the possibility of air leakage of the thermos bottle will be much smaller. We also need to pay attention to the bottom of the thermos bottle to see if there is any anti-skid design. The bottom of the thermos bottle with high quality and good quality usually adopts the anti-skid design, and the bottom pad of the thermos bottle is made of rubber.
The choice of thermos bottle is very important. Here I remind you that you must not use the poor thermos bottle, which endangers your health. Choose a healthy thermos bottle, and let the disease go away from us.
