Abstract
The invention discloses a kind of coating application methods of the electromagnetic radiation generated when elimination electric appliance use: its step includes: to apply to be covered with coating of the present invention and coating is tried reliable ground in the entire plastic casing of electric equipment products；The thickness of coating is related to efficiency is eliminated, it is high for shielding requirements, thickness can suitably be applied a bit, thickness is greater than 1MM, the purpose of the present invention and two outstanding features, unit area resistance rate is minimum, so shielding electromagnetic radiation efficiency is very high, unit resistance rate is significantly reduced than similar-type products, this coating electromagnet shield effect is higher.
Description
Technical field
The present invention relates to a kind of coating application methods of the electromagnetic radiation generated when elimination electric appliance use.
Background technique
Electromagnetic radiation pollution has been had been cited as the fourth-largest ring after water, air, noise pollution by the World Health Organization
Border pollution.To shield electromagnetic radiation, each type shielding paint and coating also come into being.Since many appliance shells are all plastics materials
Matter is molding, can most reduce the shielding electromagnetic radiation means of this kind of product cost, is to apply one layer on its shell to shield electricity
The functional paint layer of magnetic radiation, but regrettably, currently, much coating are in spraying and later period use process, to some extent
There are problems that VOC, in other words, shields electromagnetic radiation, but attracted VOC problem.
Electromagnetic shielding scheme presses technique, and be roughly divided into structural type and coating type: coating type is easy for construction with its, practical
And cost performance it is high the advantages that be used for the electromagnetic radiation protection of various electronic equipments and system, but traditional solvent based coating has two
A problem, one be coating resistivity it is not small enough, second is that the organic solvent content in coating is more than 40% or more, coating is being applied
In work and use process, a large amount of organic compound (VOC) can be volatilized, has unfavorable shadow to the physical and mental health of environment and people
It rings.It, just can not be compared with technology of the invention only according to this two o'clock.
Summary of the invention
Present invention aim to address problems set forth above, and providing one kind can be improved shielding electromagnetic radiation efficiency and match
The coating application method of the electromagnetic radiation generated when a kind of elimination electric appliance use of VOC problem is not present in side.
The purpose of the present invention is what is realized as follows: a kind of coating for eliminating the electromagnetic radiation generated when electric appliance use
Application method: its step includes:
It is applied in the entire plastic casing of electric equipment products and is covered with this patent coating and coating is tried into reliable ground；
The thickness of coating is related to efficiency is eliminated, high for shielding requirements, can suitably apply thickness a bit, and thickness is greater than 1MM.
Advantages of the present invention: the purpose of the invention patent and two outstanding features, first is that unit area resistance rate is minimum, institute
It is very high to shield electromagnetic radiation efficiency, second is that VOC problem is not present in formula.Unit resistance rate is significantly reduced than similar-type products,
This coating electromagnet shield effect is higher.
Specific embodiment:
Embodiment 1
A kind of coating application method of electromagnetic radiation generated when electric appliance use of eliminating: its step includes:
It is applied in the entire plastic casing of electric equipment products and is covered with this patent coating and coating is tried into reliable ground；
The thickness of coating is related to efficiency is eliminated, high for shielding requirements, can suitably apply thickness a bit, and thickness is greater than 1MM.
It samples Hewlett-Packard's power supply to measure as the application cross-reference: electromagnetic radiation measuring value 847V/M before being transformed, transformation
Electromagnetic radiation measuring value 2V/M afterwards.
Electric power plug socket is sampled to measure as the application cross-reference: power frequency radiometric value before being transformed: 232V/M, after transformation
Power frequency actinometry is straight: 1V/M.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical scheme and beneficial effects
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in guarantor of the invention
Within the scope of shield.
