Description
Technical Field
The application relates to the technical field of cleaning agents, for example to an electronic product charged antibacterial cleaning agent.
Background
In the long-term use of precision electronic products such as mobile phones and computers, screens and housings are stained with fingerprints, dust and grease are accumulated on receivers, earphone holes, loudspeakers, charger interfaces and the like, a large amount of bacteria are simultaneously parasitized on the parts, and therefore, diseases are spread, and the mobile phones, computers and other equipment need to be in a working state for a long time, so that the development of technologies for cleaning, bacteriostasis treatment and the like of the precision equipment such as the mobile phones, computers and the like in a live working state is very necessary.
The charged cleaning maintenance technology originated in the fortieth of the last century, belongs to a high and new technology with wide application and high technology content, and is divided into charged physical cleaning and chemical cleaning according to the cleaning method. The charged physical cleaning is to crush, decompose and peel off the dirt on the surface of a charged object by various mechanical external forces and energies to achieve the cleaning effect, can only clean the dirt on the local part of equipment, cannot deeply clean the dirt such as acid, alkali, salt, oil and the like accumulated on the surface of the equipment, and has obvious defects in the aspects of operating conditions, cleaning effect and technical innovation, so the application is limited. Charged chemical cleaning is a method of removing dirt from charged equipment using one or more chemical agents. The development of the chemical charged cleaning technology is closely related to the development of the chemical technology in the world, each revolution of the chemical technology brings about the innovation of the charged cleaning technology, and the chemical charged cleaning technology has a larger development space and becomes the mainstream of the charged cleaning technology at present. The core of the chemical cleaning technology is cleaning agent, and in the beginning of the last 50 th century, people widely used cleaning solution mainly containing chlorohydrocarbon, such as dichloromethane, trichloroethane, carbon tetrachloride, trichloroethylene and tetrachloroethylene, and due to the high toxicity of the cleaning solution, chlorofluorocarbon cleaning agent such as trichlorotrifluoroethane (CFC-113) is developed. However, in the last 80 th century, it was found that the south-pole ozone hole has a direct relationship with the generation of chlorine atoms by the decomposition of chlorocarbons and chlorofluorocarbons, and it was called "ozone depletion enhancing substance (ODS)". In order to protect the ozone layer, the vienna convention on ozone protection and the montreal protocol on ozone depleting substances have been established to limit the use of ODS materials containing chlorocarbons and fluorochlorocarbons in electrified cleaning, and currently, the use of ODS cleaning agents is essentially stopped in western developed countries. In recent 20 years, some chemical research institutions in japan and the usa developed a lot of non-ODS charged cleaning agents, such as 2,3-dihydrodecafluoropentane, and nonafluorobutyl methyl ether and nonafluorobutyl ethyl ether produced by 3M, which are introduced by dupont, and have the characteristics of zero Ozone Depletion Potential (ODP), low Global Warming Potential (GWP), no combustion/low toxicity/chemical stability, and the like, and are widely applied to the charged cleaning and maintenance work of precise instruments. At present, vienna convention and Montreal protocol are comprehensively added in China, an integral elimination ODS plan in the China cleaning industry is provided, and the use of cleaning agents such as CFC-113 is completely stopped, so that domestic companies such as Lanxing and Qiwei are invested in a large amount of manpower and material resources to develop safe and environment-friendly electrified cleaning agents for precision equipment, and part of research results are applied to production practice.
In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: the existing charged cleaning agent has complex components and is not environment-friendly.
