储存 / Storage
DCP 是易制爆危险化学品，储存温度在 30℃以下，贮存在阴凉、干燥、通风的 仓库。远离热源、明火。严禁与酸类、还原剂、还原剂、自燃物品等混合存放。严禁与酸类、易燃物、有机物、还原剂、自燃物品、遇湿易燃物品等混运,避免日光、热源和明火。轻装轻卸，避免撞击、碰撞等。
Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality. Harmony Chem Enterprise Limited recommends a maximum storage temperature (T max) for each organic peroxide product.
For DCP Ts max. = 30℃ (86℉)
When stored under the recommended storage conditions, DCP will remain within the specifications for a period of at least 12 months after delivery.
Organic peroxides are thermally unstable substance, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.
DCP SADT: 75℃ (167℉)
