In today's pursuit of quality life, a high-quality thermos cup has become an indispensable part of our daily life. So, how to pick a qualified and suitable thermos mug among many brands and models? Below, let's take a look at the three major tricks of thermos cup selection!
The first trick: insight into the material of the liner
The material of the inner tank is the key to judging the quality of the thermos cup. The common liner materials on the market are mainly 201 stainless steel, 304 stainless steel and 316 stainless steel.
201 stainless steel: It belongs to industrial grade stainless steel, which has poor corrosion resistance, is easy to rust when encountering acidic solutions, and rust spots will appear even in water, so it is not recommended to buy.
304 Stainless Steel: Recognized as food grade stainless steel, it has good processing properties and corrosion resistance. When purchasing, you can pay attention to the marks such as SUS304 and S304XX-8 on the bottle mouth or inner tank.
316 stainless steel: As a medical grade stainless steel, its corrosion resistance is better than that of 304 stainless steel, but ** is slightly higher. When purchasing, you can pay attention to the marks such as SUS316 and S316xx on the bottle mouth or inner tank.
The second trick: check the thermal insulation performance
Thermal insulation performance is an important indicator to measure the quality of the thermos cup. We can test the heat preservation effect of the thermos cup through a simple experiment: fill the thermos cup with boiling water, screw the lid tightly, wait for 2 or 3 minutes, and then touch the surface of the cup with your hands. If you find that there is a warm feeling, it means that the vacuum layer has been lost in this thermos cup, and the insulation effect of the inner tank is not good, so it is recommended to avoid buying.
The third trick: test the sealing performance
The sealing performance is related to the use experience of the thermos cup. Similarly, we can test the tightness of a thermos cup with a simple experiment:Fill the thermos cup with boiling water and screw the lid tightly and turn it upside down for five minutes. If the thermos cup leaks, it means that its sealing is not good, and it should be carefully selected.
To sum up, to choose a qualified thermos cup, we need to consider the three aspects of liner material, thermal insulation performance and sealing performance. Only by mastering these three ** rules, can we easily select a satisfactory thermos cup, so that the quality of life starts from the details!
