Food Desiccant In The Confined Space Will Explode With Water Is True?

Food Desiccant in the confined space will explode with water is true?
There are many online news or news reports, food Desiccant will explode. Xiaobian in a responsible attitude, consulting Dingxing Desiccant technical staff, he told Xiao Bian, food Desiccant points there are many: silicone Desiccant (transparent particles), lime Desiccant (white lumps), minerals Desiccant (brown ball). Raw materials are non-toxic, please rest assured. The only thing to notice is the lime Desiccant because the lime Desiccant swells with water and generates a lot of heat. Only the Desiccant of lime Desiccant of this kind of food can explode in the confined space, so when we encounter food Desiccant, we must distinguish the type of Desiccant, we can not blindly think that the Desiccant will explode. Liao on.
Food lime Desiccant can be seen in daily life, mainly from moisture, reduce food humidity, prevent food deterioration and so on. Food lime Desiccant really so dangerous? Water will explode? Yesterday, with these questions, Xiaobian consulted Dongguan University Laboratory of Chemistry, a senior lab teacher Ma. Ma teacher said that the food lime Desiccant in the confined space water explosion.
To prove this conclusion, Xiaobian and the students conducted an experiment on a playground. Students poured 3 bags of food lime Desiccant into a mineral water bottle, poured 100 ml of water into the bottle, and immediately tightened the bottle cap. About 30 seconds later, the bubbles began to bubble water bottles, water began to boil, the bottle constantly shaking and gradually distorted. About 1 minute later, with a loud bang, a mineral water bottle flew directly into the air like a rocket and ran out of a dozen meters. When Xiao Bian find the water bottle 78 meters away from the experimental location outside the bottle cap and the bottom has disappeared, the bottle is very hot.
Ma teacher Xiaobian explain one of the principles, the main ingredients of food lime Desiccant used in experiments is calcium oxide, calcium oxide in water with rapid chemical reaction, the formation of alkaline chemical calcium hydroxide (calcium hydroxide is more corrosive) An instant release of a large amount of heat, the heat so that the bottle of water into a steam and the rapid expansion, the final explosion. "The premise of the explosion is in a confined space, explosion splashed lye on the human body has a corrosive effect," Ma said.
Due to the current lime Desiccant is more dangerous, so the market gradually replaced by silica gel Desiccant. Food Desiccant is relatively safe silica gel Desiccant, because the silica gel Desiccant is a non-toxic environmentally friendly moisture-proof products, product quality in full compliance with ROHS, REACH and other environmental requirements, absolutely free of DMF (dimethyl fumarate fumarate) and other harmful substance. Silicone is also FDA's only approved Desiccant material that comes into direct contact with food and pharmaceuticals. Compared to other Desiccant, silica gel Desiccant is used in food moisture is relatively safe.
Mineral Desiccant its salient features are:
1, environmental protection, safety, can be widely used in medicine, food, feed field. Small amount of food, will not endanger life. (Beware of eating)
2, high hygroscopicity, strong ability to smell, non-toxic and tasteless, non-contact corrosion, no environmental pollution. Moisture absorption than the silica Desiccant higher than 50% to 100%. Natural structure can selectively adsorb formaldehyde and gaseous sulfide and other toxic gases.
3, the use of long cycle, renewable use.
4, after moisture absorption is not reverse osmosis, to ensure that the Desiccant packaging is always in a dry state. Moisture before and after almost no change in physical form, there will be no "broken bags" phenomenon.
5, the rules of high-strength spherical particles, can increase its mobility to ensure that products in the transport, packaging process is not broken, does not produce dust Desiccant. At the same time, even if the product is immersed in water for a long time, its strength and shape will not change, which can better enhance its regenerability.
