It is another scorching summer, and barbecue modes are successively opened across the country. Summer is the season with high incidence of hazardous chemical safety accidents. In order to raise the public’s awareness of safe production, the State Council’s Safety Committee conducts Safe Production Month every June. The theme of this year's safety month activity is: "Life is the first, safe development". The editor is here to share with you a few tips on the safety of methyl ethyl ketone peroxide curing agent, and I wish you all a smooth and safe career.
Methyl ethyl ketone peroxide (MEKP) is a highly active, thermally unstable substance. Improper storage, transportation and handling can cause self-accelerated decomposition of the product, and may also occur:
Decompose flammable materials and burn rapidly
The product separates from the solvent and explodes upon collision or vibration
Reacts violently with pollutants
Corrosion and chemical burns
Organic peroxides are decomposed by heat and emit heat. When the ambient temperature is too high, the heat generated by decomposition will not be released to the environment, and the heat will accumulate and self-accelerating decomposition will occur.
The self-accelerating decomposition temperature SADT of qualified MEKP curing agent is greater than 50℃, and it can be safely stored and transported at room temperature (SADT=Self Accelerating Decomposition Temperature).
MEKP undergoes self-accelerating decomposition in a closed container, with the release of heat and a large amount of gas, which can cause thermal explosion.
