Electronic instrument detergent

Abstract

The invention provides a cleaner of an electronic instrument, comprising phosphate, surface active agent, antistatic agent, pH value regulator and deionized water; the weight percentage of all the components is: 3 percent to 12 percent of the phosphate, 3 percent to 12 percent of the surface active agent, 3 percent to 8 percent of the antistatic agent, 2 percent to 8 percent of the pH value regulator and the rest is the deionized water; the pH value of the mixing liquid is 11 to 12; the cleaner is applicable to the cleaning technique of a circuit board and parts of the electronic instrument, can effectively remove organics and dusts and the like stuck in the long time operation of the electronic instrument, can eliminate static, has low corrosion and safe and reliable use, does not damage the ozone layer, conforms to the requirements of environmental protection, etc. and has reasonable formulation design, simple preparation technique and low cost; and the cleaned waste liquid is convenient to be treated and discharged.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based cleaning agent for electronic instruments. Background technique [0002] During the use and operation of precision electronic instruments, they are often eroded and damaged by static electricity and pollutants, causing failures in electronic instrument circuit equipment and affecting the normal operation of the instrument. This is because various types of electronic instruments are affected by environmental factors during long-term continuous operation. Under the action of its cooling air supply system and its own electromagnetic field, these devices will gradually be eroded and damaged by dust, oil, moisture, salt, static electricity, charged particles, various corrosive substances and gases in the environment, such as these pollutants The "soft fault" caused by the additional "microcircuit" effect formed makes the heat dissipation performance of the electronic instrument worse...

Problems solved by technology

[0004] The existing cleaning methods for electronic instruments mainly use leather tiger blowing, brushing with a hair brush, wiping with alcohol cotton balls, etc. These methods have low efficiency, poor cleaning effect, hidden parts cannot be touched, and pollutants are difficult to completely remove. prone to human error

For this reason, according to the needs of this type of equipment cleaning, some electronic instrument cleaning agents have appeared on the market, but their performances such as high voltage resistance, high insulation, non-combustibility, non-corrosion, and environmental protection have shortcomings, and most of them are consumed. Ozone layer substances (ODS) products are facing the situation of being eliminated with the improvement of national environmental protection requirements
