Problems solved by technology
Most of the existing cleaning agents for radio equipment are solvent-based. The disadvantages of these cleaning agents are that the cleaning effect is not very ideal, and the electronic component materials after cleaning are prone to black surface layer, which brings troubles to subsequent processing, especially for precision components. The processing of the device causes confusion; secondly, it is highly corrosive to the equipment and incr

Abstract
The invention provides a cleaner for radio equipment, comprising inorganic salt, surface active agent, penetrating agent, corrosion inhibitor, pH value regulator and deionized water; the weight percentage of all the components is as follows: 3 percent to 8 percent of the inorganic salt, 5 percent to 9 percent of the penetrating agent, 5 percent to 10 percent of the surface active agent, 1 percent to 5 percent of the corrosion inhibitor, 1 percent to 5 percent of the pH value regulator and the rest is the deionized water; the pH value of the mixing liquid of the components is 11 to 12, the color is colorless and transparent without pungent smell; the cleaner has the functions of high efficiency and easy cleaning to the radio equipment, can clean the oil stain and rusty spot on the surface of electronic component completely, can prevent the surface of the electronic component from generating rusty spot again, also can shorten the cleaning time and improve the working efficiency; the cleaner is a water soluble cleaner, has low corrosion to the equipment, reduces the production cost effectively and has safe and reliable use.
Description
technical field [0001] The invention relates to a cleaning agent, in particular to a water-based cleaning agent for radio equipment. Background technique [0002] The cleaning of electronic components is an indispensable process link in the process of processing, assembling, storing and repairing the components. Since the amount of electronic precision components of radio equipment is quite large, the workload of cleaning such electronic components and the amount of cleaning agent used will definitely increase accordingly. At present, the cleaning methods for electronic components mainly include immersion washing, spray washing, and ultrasonic cleaning. No matter which cleaning method is adopted, a cleaning agent is required. A typical procedure is to clean in the low pH range to remove mineral scale contaminants, followed by a high pH wash to remove organics. Detergents are added to some cleaning solutions to help remove heavy biological and organic debris, while chelates...
