Description

Technical Field

[0001] The utility model relates to the field of transportation devices, in particular to a methyl methacrylate transportation device with a moisture-proof storage structure. Background Art

[0002] Methyl methacrylate (MMA), also known as methyl methacrylate, is an organic compound with the chemical formula C5H8O2. It is a colorless liquid, slightly soluble in water, and soluble in most organic solvents such as ethanol. It is mainly used as a monomer for organic glass and is also used to manufacture other resins, plastics, coatings, adhesives, lubricants, wood and cork impregnation agents, paper polishes, etc. Methyl methacrylate is a flammable and explosive organic solvent. It is a liquid at room temperature and pressure. It is an organic compound with the characteristics of a colorless and transparent liquid, is volatile, has a pungent odor, and is toxic to the human body.

[0003] Methyl methacrylate is a volatile substance, which means it can evaporate quickly in the air to form vapor. Methyl methacrylate is flammable and explosive. During transportation, when methyl methacrylate is first introduced into the transport device, it is very easy to form an explosive mixture with the air, which poses a safety hazard. Methyl methacrylate is slightly soluble in water and may be affected by oxygen and moisture in the air to undergo oxidation and hydrolysis reactions. These reactions may cause its color to darken, its odor to change, and its purity to decrease.

[0004] Therefore, in view of the safety hazards of methyl methacrylate during filling and the possible reaction with oxygen and moisture, a methyl methacrylate transportation device with a moisture-proof storage structure can be designed to eliminate the safety hazards while ensuring that the properties of methyl methacrylate do not change.
