Silicone:
Explanation:
The seal ring is a small elastic accessory that is widely used in various containers and equipment in daily life, such as water bottles, tea cans, pressure cookers, etc. Its main function is to prevent liquid or gas leakage and maintain the tightness of the container. The common sealing ring materials are silicone, rubber, etc. These materials have good flexibility, elasticity and temperature resistance, and can be tightly fitted to the container mouth, effectively blocking the entry of air and moisture, thereby extending the shelf life of the item and ensuring the safety of use. Although the sealing ring is small, it plays an important role in daily life and is an important accessory to ensure the storage and use of goods.
Material:
First, silicone: silicone is a common sealing ring material, it has good flexibility and elasticity. The sealing ring of this material can be tightly fitted to the edge of the mouth of the tea can or water bottle, forming a good sealing effect. Silicone itself is a non-toxic, odorless material, which makes it very safe when in contact with food. For example, in some high-quality tea cans, the use of silicone seals can effectively prevent tea from being damp and smelly. Moreover, the temperature resistance of the silicone sealing ring is also good, and it can maintain its performance within a certain temperature range, whether it is a hot water bottle or an ordinary water bottle, it can be well adapted.
Second, rubber: Rubber sealing ring is also a common type. Natural rubber has good wear resistance and anti-aging properties. It can withstand a certain amount of pressure to ensure that it will not be easily damaged during frequent use, such as when unscrewing and tightening the water bottle cap. Moreover, the sealing performance of rubber is also quite excellent, which can effectively prevent liquid leakage. However, the temperature range of rubber may be slightly narrower than that of silicone, but in general, it is enough to meet the needs of water bottles in daily use.
The sealing ring function
1, preservation function
For tea cans, the primary role of the sealing ring is to keep fresh. Tea is a kind of easy to absorb moisture and smell. If the seal of the tea can is not good, the moisture and odor in the air will enter the can, leading to the deterioration of the tea. Green tea, for example, loses its refreshing aroma when wet and becomes bitter. A good sealing ring can block the entry of air, so that the tea can be preserved in a relatively stable and dry environment, extend the shelf life of the tea, and maintain its original flavor.
2, leak-proof function
In the water bottle, the role of the sealing ring is self-evident. It prevents water from leaking out of the bottle. Whether it is a water bottle carried during sports or a glass water bottle for daily use, the seal ring is like a loyal "goalkeeper". When we are in the process of exercise, the water bottle is jolted and collided, the sealing ring can be tightly fitted to the mouth and cap of the bottle to ensure that the water will not overflow, avoid wetting the clothes and other items in the bag, and facilitate us to drink water anytime and anywhere.
