Desiccant is very common in our life, which is mainly divided into silica gel desiccant, live ore desiccant, montmorillonite desiccant, calcium chloride desiccant, quicklime desiccant, etc. many people will have such a question: is desiccant flammable? The following Xiaobian of Minghui will talk about the flammability of these desiccants, as follows:
① Silica gel desiccant: it is characterized by good thermal stability and high temperature resistance. In the process of producing silica gel desiccant, it needs to be dried at high temperature. Therefore, after the silica gel desiccant is baked at a high temperature above 120 ℃, it can also be reused. Therefore, silica gel desiccant is not flammable.
② Live ore desiccant: it is a pure natural mineral desiccant, which is mainly made of natural attapulgite clay from nature through granulation, high-temperature drying and other physical methods. It also needs to be dried at high temperature in the production process, so the live ore desiccant is not flammable.
③ Montmorillonite desiccant: it is made of pure natural montmorillonite by drying and activation. The raw material itself is stone, which can withstand high temperature, so it is obvious that montmorillonite desiccant is not flammable.
④ Calcium chloride desiccant: with anhydrous calcium chloride and calcium chloride dihydrate as the main raw materials, the melting point is as high as 772 ℃, the boiling point is as high as 1600 ℃, and it also needs to be dried at high temperature in the production process, so calcium chloride desiccant is not flammable.
⑤ Quicklime desiccant: the main component is calcium oxide (CAO), which itself requires high temperature calcination of limestone above 1200 ℃, so quicklime desiccant is not flammable.
Therefore, from the raw materials and processing process of various desiccants, they are not inflammables. But what about the desiccant after packaging? As we all know, most of the desiccant packaging materials belong to combustibles, and the packaging cartons of desiccants also belong to combustibles. Therefore, for the finished desiccants, it is still necessary to keep away from open flames and pay attention during storage.
