Art sorb是什么？

到官网上看看上面说：
ART SORB is a type of silica gel well suited to the task of controlling humidity in display cases. It is a moisture-sensitive silica material which adsorbs and desorbs moisture in order to offset changes in relative humidity. Its main use is to create a suitable microclimate inside showcases placed in rooms which are either too dry or too wet or have fluctuating climate.

我翻译了一下就是：
ART SORB 是一种硅胶。它很适合控制展览台湿度。它是种对湿气敏感的硅胶，可以吸收并且释放水汽，从而弥补在湿度方面的变化。ART SORB主要使用在过于干燥或湿润或者有环境变化的室内展柜内，用来制造出一种适合物品存放的微环境。
