On November 26, 2013, Qidong City Public Security Weibo issued a notice. A junior high school student in Taiyuan City accidentally put the desiccant in the seaweed into the thermos bottle, causing the thermos to explode and his eyes almost blind. This is because the lime desiccant is placed in the brand seaweed. The main component of the lime desiccant is calcium oxide.
After water absorption, it turns into calcium hydroxide and releases a large amount of heat. The air expands and explodes. Chunwang reminds me that parents and friends, after not knowing the composition of the desiccant, after disassembling the package, try to discard the desiccant and keep away from the child to avoid unnecessary harm.
At present, the lime desiccant has been gradually replaced by a silica gel desiccant, which is a physical adsorption desiccant rather than a chemical desiccant, which is very safe and environmentally friendly.
