Abstract

The invention provides a primary high-voltage circuit cleaning agent, which comprises the following compositions in percentage by mass: 1 to 20 percent of polyethylene glycol octyl phenylether, 1 to 20 percent of nonylphenol polyoxyethylene ether, 1 to 3 percent of n-propyl bromide, 10 to 20 percent of C2Cl3H3, and 5 to 60 percent of C3HCl2F5. The invention also provides a method for preparing the primary high-voltage circuit cleaning agent, which comprises the step of placing the components into a closed container in proportion to react for one hour at the temperature of between 20 and 30 DEG C under normal pressure. The cleaning agent has no environment pollution, low corrosivity, strong physical decomposition capacity, and safe and reliable use, and can quickly and thoroughly eliminate dust, oil stain, carbon residue, salinity, humidity, metal dirt and various charged particles on the surfaces and deep layers of various precision equipment circuits, effectively eliminate 'soft fault', ensure the best working state of equipment and reduce the maintenance cost.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a high-voltage primary circuit cleaning agent. Background technique [0002] Due to the operation of program-controlled switches, mobile communication equipment, microwave communication equipment, wireless paging equipment, computer systems, automation control equipment, film and television equipment, radio and television equipment, remote control, remote sensing, telemetry equipment, high-precision instruments, and household appliances, Constantly subject to pollution and static electricity, circuit (board) leakage, electrochemical corrosion, and breakdown of components caused by electrostatic discharge will cause hard breakdown, burning or permanent failure of the component medium, and soft breakdown will cause device performance. Deterioration or parameter index drop. [0003] The root cause of power equipment accidents is that dirty substances are deposited on the surface of insulators, b...
