Description and purpose:
Blue silica gel desiccant is a desiccant with moisture absorption and anti-rust functions. Its appearance is blue or light blue glassy particles, which can be divided into two forms: spherical and block. Its characteristic is that the color changes from blue to pink after absorbing moisture, so it is also called an indicator desiccant.
This desiccant has a wide range of applications. First of all, when instruments and equipment are used in a sealed state, it can prevent moisture from corroding and damaging them. At the same time, the color change can directly indicate the ambient humidity, providing a real-time humidity monitoring function. Secondly, when used in conjunction with ordinary silica gel desiccant, the water content of the desiccant can be judged by the color change of the blue silica gel, and the relative environmental humidity can be inferred from this. In addition, blue silica gel desiccant is widely used in various packaging, such as precision instruments, leather products, shoe materials, clothing, food, pharmaceuticals and household appliances, to keep products dry during storage and transportation. , to prevent moisture from causing damage to the product.
