Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically, to a trimethylsilane raw material storage tank which is convenient for maintenance. Background Art

[0002] Trimethylsilane is colorless, flammable, and highly volatile. It is mainly used as a plasma corrosive in the semiconductor industry and can also be used as an intermediate in the production of organosilicon compounds. When exposed to the air, it easily reacts with moisture to produce hydrogen chloride. Therefore, it is generally necessary to use raw material storage tanks for storage. If a leak occurs, it will have a strong irritating effect on the human respiratory tract, eyes, and skin mucosa, and easily cause environmental pollution. Therefore, the raw material storage tanks of trimethylsilane must be regularly inspected to reduce maintenance time.

[0003] In the existing technology, the volume of trimethylsilane raw material storage tanks is generally large, and ladders are needed for climbing during maintenance. However, the raw material storage tanks are generally placed outdoors. These ladders are prone to rust and loss of strength after long-term exposure to the sun and rain, posing a safety hazard when climbing. At the same time, the trimethylsilane raw material has the characteristic of being easily volatilized when heated. When the external environment rises steadily, the trimethylsilane raw material is easily volatilized when heated. Utility Model Content
