Types and functions of desiccant

Introduction: desiccant is very common, so what are the types and functions of desiccant? Through the safety net of Baibai for detailed understanding Desiccant is not the only thing you see in food packaging There are many kinds of desiccant, and different kinds of desiccant have different functions What are the types and functions of desiccant? Learn about relevant food additives through the safety net According to the adsorption mode and reaction products, it can be divided into physical adsorption desiccant and chemical adsorption desiccant Physisorption desiccant includes silica gel, alumina gel, molecular sieve, activated carbon, bone charcoal, charcoal, mineral desiccation, or activated clay Its drying principle is to adsorb water molecules in their own structure through physical means Chemical adsorption desiccant classification: the first type is acid desiccant, including concentrated sulfuric acid, phosphorus pentoxide, anhydrous copper sulfate, etc.; the second type is alkaline desiccant, including solid caustic soda, lime and alkali lime (mixture of sodium hydroxide and calcium oxide), etc.; the third type is neutral desiccant, such as anhydrous calcium chloride, anhydrous magnesium sulfate, etc Through understanding, I believe you know the types and functions of desiccant, desiccant is essential in life If you want to know about this aspect of food safety knowledge, such as what hazards desiccant has, how to use food safety detector, etc., you can come to Baibai safety net Editor in charge: he xianrob
