Abstract

The invention discloses a cleaning agent for electric mechanical equipment. The cleaning agent comprises the following components according to mass percentage: 2 to 12% of dichloromethane, 15 to 30% of tetrachloroethylene, 5 to 25% of D40 solvent oil, 16 to 35% of monofluorodichloroethane, 30 to 40% of D60 solvent oil and 0.1 to 1% of orange peel oil. The cleaning agent for the electric mechanical equipment is economical and practical and good in cleaning effect, causes no corrosion to a metal, aluminum, non-metal or painted surface, and is an aviation chemical product effectively used for cleaning a civil aircraft.

Description

technical field [0001] The invention relates to cleaning of aircraft mechanical parts and aircraft electrical equipment parts, and belongs to the field of aviation cleaning agents. Background technique [0002] Now for the cleaning of electrical equipment, it is necessary to disassemble the electrical equipment before cleaning. For the cleaning of mechanical equipment, manual grinding and cleaning are required. Therefore, the operation is complicated, time-consuming and labor-intensive. In the current patent CN1616630A, the cleaning agent for electrical and mechanical equipment disclosed is to dehydrate trichlorethylene with anhydrous sulfuric acid and color-changing silicic acid to improve the insulation value of trichlorethylene and use it as a cleaning agent, but trichlorethylene is heated or At high temperature, it reacts with oxygen to generate highly toxic phosgene, which is harmful to the human body and corrodes composite materials and paint surfaces.
