1. The important role of silicone in stainless steel insulated cups
Stainless steel insulated cup is a common type of insulated cup, which has excellent insulation effect and durability. Silicone plays an important role in stainless steel insulated cups. The main functions are as follows:
(1) Sealing: Silicone can tightly adhere the cup lid and body together, preventing the loss of temperature and moisture, thereby improving the insulation effect.
(2) Leak proof: Silicone can ensure the sealing of stainless steel insulated cups, preventing water from leaking out and thus avoiding water droplets from dirtying clothes, backpacks, and other items.
(3) Anti slip properties: Silicone can increase the friction of stainless steel insulated cups, making them more stable to hold and less prone to slipping.
(4) High temperature resistance: Silicone can usually withstand high temperatures up to around 200°C, which meets the usage requirements of stainless steel insulated cups.
2. Manufacturing method of silicone gel
Currently, most stainless steel insulated cups on the market use silicone as the sealing material. So, how is silicone made?
Silicone is mainly made by high-temperature calcination of substances such as silicates, silicon dioxide, and water. The specific manufacturing method is as follows:
(1) Manufacturing strong acidic or strong alkaline hydrolyzed colloids;
(2) Filter and dry the hydrolyzed colloid;
(3) Decompose the substance into silica gel with a certain particle size by high-temperature calcination.
During the production process, the composition and hardness parameters of silicone are strictly controlled to ensure its sealing and anti slip properties.
3. Conclusion
Silicone plays a very important role in the manufacturing process of stainless steel insulated cups. The application of silicone ensures the sealing, leak proof, and slip resistant properties of stainless steel insulated cups, making them an indispensable household item in people’s daily lives.
