What happens when the desiccant meets water

Introduction: there are many kinds of desiccants Not all desiccants will explode when they encounter water We should choose according to different types of desiccants in our life Desiccant is quite common in daily life Its main function is to cool down and prevent moisture Recently, there has been an explosion of desiccant, which makes many people flinch They don't know how to choose desiccant What will happen to desiccant when it encounters water? What are the hazards of desiccant? These problems can be directly solved through the safety net of Baibai To understand There are many kinds of desiccants At present, quicklime desiccant, calcium chloride desiccant, mineral desiccant and silica gel desiccant are common Among them, silica gel desiccant is green and environmentally friendly, and its moisture absorption effect is not as strong as that of quicklime desiccant In general, there are many fine silica gel used in drugs, which is relatively safe Now some foods also have this kind of desiccant, which will not react greatly when encountering water, and silica gel desiccant can also be reused; As for the quick lime desiccant, compared with the other three desiccants, the cost is a little lower, but the effect of moisture absorption is strong, which used to be more, and now it is rarely placed in the food; the utilization rate of mineral desiccant is also very high, some bags and clothes will be placed in the packaging Among the above desiccants, most of them are quick lime desiccant and silica gel desiccant In fact, different kinds of desiccants have different ingredients Not all desiccants will explode when they encounter water For example, quick lime desiccant, its main component is calcium oxide, calcium oxide will produce a sharp chemical reaction after encountering water, and release a lot of heat instantly If a small amount is added, the plastic bottle may become hot and deformed Once the amount is added to a certain extent, and the plastic bottle is in a closed state, the plastic bottle may burst, and the heat generated in an instant may also burn people To sum up: "what will happen to the desiccant when encountering water" today, not all desiccants will cause explosion after encountering water, and the statement that the desiccant will explode when encountering water is not very accurate The composition of different kinds of desiccant is different, so it is necessary to properly handle the desiccant in daily life To learn more about food additives and food safety, you can directly log in to Baibai safety net Editor in charge: he xianrob
