1. Aluminum alloy thermos cup
Aluminum alloy thermos cups occupy a certain share of the market. They are lightweight, unique in shape and relatively low in price, but their thermal insulation performance is not very good. Aluminum alloy is a material with excellent thermal conductivity and heat transfer performance. Therefore, when the thermos cup is made of aluminum alloy, it is usually necessary to add an insulation layer to the inner wall of the cup to improve the insulation effect. In addition, aluminum alloy is also prone to oxidation, and the cup mouth and lid are prone to rust. If the sealing is poor, it is easy to cause water leakage.
2. Stainless steel thermos cup
Stainless steel thermos cups are the most widely used thermos cups on the market. Stainless steel has good thermal insulation properties and corrosion resistance, as well as good mechanical properties and formability. Therefore, stainless steel thermos cups not only have good heat preservation effect, but also have better durability and are easy to clean and maintain.
3. Comparison between aluminum alloy and stainless steel thermos cups
The performance differences between aluminum alloy thermos cups and stainless steel thermos cups mainly lie in the following points:
1. Thermal insulation performance: The thermal insulation performance of stainless steel thermos cups is much better than that of aluminum alloy thermos cups. The insulation effect can last for a long time and is not easily affected by the ambient temperature.
2. Durability: The stainless steel thermos cup has high material strength and is not easily deformed or damaged, so it has a long service life.
3. Safety: The material of the stainless steel thermos cup meets hygienic standards and will not produce harmful substances or cause harm to the human body. Aluminum alloys contain aluminum elements, and long-term use may easily have adverse effects on human health due to the dissociation of aluminum ions.
4. Conclusion
Based on the above comparison, stainless steel thermos cups have better insulation effects, better durability and safety, so they are more suitable as a material choice for thermos cups. The aluminum alloy thermos cup needs to work hard to strengthen the insulation layer to improve its insulation performance.
