Cross ketone of oxidation armour second (MEKP) is tall active, hot not stable material. Store, carry and the operation is undeserved can bring about a product to be decomposed quickly oneself, still may happen:
Volatile decompose
Decompose tinderbox, quickness burns
Product from the separate out in solvent, encounter collision or shake produce explosion
Produce severe reaction with contaminant
Corrode and chemical and burnable
Volatile decompose
Organic oxide be heated is decomposed and emit quantity of heat too. Pass when environmental temperature tall, the quantity of heat that decomposes generation has not enough time to be released to the environment, quantity of heat is accumulated, can happen to be decomposed quickly oneself.
Quicken of agent of eligible MEKP solidify oneself decompose temperature SADT to be more than 50 ℃ , safety stores and can carry below normal temperature (SADT=Self Accelerating Decomposition Temperature) .
MEKP happens to be decomposed quickly oneself inside the container that close, accompany give off quantity of heat and generation a large number of gas, can cause hot explosion.
Decompose tinderbox, quickness burns
High quality oxidize too flash point of agent of solidify of armour second ketone is higher (be more than SADT) , not combustible. Without distillation dehydrate pass product of ketone of oxidation armour second, existence fourth ketone remains, flash point is relatively inferior. The flash point that qualification passes lotion of solidify of ketone of oxidation armour second is general prep above 35 ℃ .
Add the inferior product of methanol, flash point is low () of ℃ of =12 of methanol flash point, increased the dangerous sex of the product greatly, do not accord with safe level.
Once,pass lotion of solidify of ketone of oxidation armour second ignition, combustion rate is splitting.
Encounter collision or shake produce explosion
Oxidize too armour second ketone is pure taste pair of mechanical collision or attrition is sensitive, have volatile (report according to abroad, ISIS ever had used ketone of oxidation armour second pure taste the explosive that make, use at horror to assault) . To assure product security, must add safe dissolvent to regard as decrease quick agent, control content of total active oxygen to be less than 10% .
Pass lotion of solidify of ketone of oxidation armour second high gradely, benzene of use low-test adjacent is ester of 2 formic acid, adipose the safe dissolvent such as a group of things with common features ester is decreased quick, normal Chu Yunhe is done not have below operation condition volatile.
Water content of inferior solidify agent is high, to reduce cost, a large number of use easy volatilization methanol serves as add solvent. Cross ketone of oxidation armour second not dissolve at water, in Chu Yunhe unit process of cargo bandling, because temperature changes, methanol volatilizes wait for an element, meeting hair produce is statified. MEKP of separate out tall pH indicator is encountered shake or bump produce explosion extremely easily.
Encounter contaminant to produce severe reaction
Cross ketone of oxidation armour second to be material of fast response active, encounter reducer (for example: Amine) , acerbity, alkaline with heavy metal compound (for example: Accelerant, desiccative and metallic black) wait, can happen acuteness decompose, give off a large number of quantity of heat and can burn gas.
Agent of high quality solidify uses high grade raw material, use distillation dehydrate technology, the matter content in the product is low, stability is tall.
Inferior solidify agent is used cheap raw material, use desiccative evaporation, the likelihood introduces metallic salt kind foreign matter, product stability is poor, put in safe hidden trouble. Get pollution cross stability of agent of solidify of ketone of oxidation armour second to reduce, below room temperature likelihood happening is decomposed quickly oneself, cause fire or explosive accident.
Corrode and chemical and burnable
Oxidize too armour second ketone is mordant. With the skin the contact can cause serious chemical and burnable; to enter an eye to be able to cause a loss, even blindness; is taken by accident can bring about esophagus, enteron burnable, perforative, die even.
Eye contact: Use clear water to rinse at least 15 minutes continuously instantly, subsequently go to a doctor.
Skin contact: Eliminate suffers contaminative clothings and shoe, use soap and water clean the skin thoroughly.
Take by accident: Do not urge spit, drinkable and many milk or water, instantly go to a doctor.
