Abstract

The invention discloses a preparation process of a moisture-removing agent for a transformer substation cabinet, belonging to the technical field of preparation processes of moisture-removing agents.The preparation process of the moisture-removing agent for the transformer substation cabinet is characterized in that the moisture-removing agent is prepared from calcium chloride, phosphorus pentoxide, sulfuric acid, calcium carbonate, quick lime and an organic solvent in parts by weight. According to the invention, calcium chloride is added, so the moisture absorption performance of the productis good, absorbed water can be evaporated under the action of phosphorus pentoxide and quick lime, toxic gas generated in sulfuric acid and an organic solvent is reduced by adding calcium carbonate,irritant gas can be eliminated by adding calcium carbonate, and therefore, the product cannot cause harm to a human body and is allowed to have light fresh scent, constructors can work better in the transformer substation cabinet, and the harm of harmful gas to the constructors is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation technology of a moisture-repellent agent, in particular to a preparation method of a moisture-repellent agent for a substation cabinet. Background technique [0002] Due to the heavy rainfall in southern China, some indoor storage cabinets and substation cabinets in the south are prone to moisture. Among them, the interior of the substation cabinet is prone to moisture, which may cause short circuits in internal electrical equipment, requiring construction workers to go in for maintenance. Accidents may occur due to construction workers not paying attention or under the premise of making mistakes. The mild ones are hospitalized for observation, and the severe ones directly lead to no signs of life, and some desiccant agents are needed to remove the moisture in the substation cabinet to make it reduce the occurrence of such incidents. [0003] The moisture repellant on the market has poor hygr...
