用英文介绍一下水凝胶不耐低温。

Water gel is a hydrogel that is widely used in various fields such as agriculture, industry, and medicine. However, one of its limitations is its poor tolerance to low temperatures. When the temperature drops below a certain point, water gel tends to freeze, which can cause it to lose its structure and effectiveness. This makes it difficult to use in cold environments or during winter months. Therefore, it is important to consider the temperature conditions when using water gel and to store it properly to avoid exposure to low temperatures.
