Abstract
The present invention is a kind of magnetothermal glass absorbing and shielding electromagnetic wave, and its manufacture method is according to a certain percentage the mixture heating up of magnetic substance glass to be caused the two all to be in high temperature fused state.Rely on the irregular thermal motion of molecule and stir fully and make magnetic substance be dissolved in fully that glass constitutes back among the molecule and the magnetic glass made with specific function with individual molecule, atom or ionic form, it can absorb with the form of self-heating, shielding electromagnetic wave, and purposes is extremely widely arranged in people's lives, medical treatment and industrial production and military field.
Description
Glass is a kind of inorganics, and its major ingredient is a silicon-dioxide, and it is " transparent " to hertzian wave.Often need some that good light permeability is promptly arranged in people's lives and industrial production, glass that again can shielding electromagnetic wave is as the viewing window of household microwave oven; The industrial various high-strength electromagnetic shield etc. of observing, this glass be thin sweet, small wire netting of folder between layer glass normally.Obviously, very high, the complex process of this glass cost.
The invention provides a kind ofly can absorb, the hot glass of transparent magnetic of shielding electromagnetic wave.
The present invention is blended in magnetic substance among the glass and the special glass of making equably with individual molecule, atom or ionic form.Thereby magnetic substance is responded to the external electromagnetic ripple in the mode of forced vibration and is driven glass and constitute molecule and vibrate together electromagnetic energy replacement is become the heating of the hot glass of magnetic and to dissipate in glass, realize absorption of electromagnetic wave and shielding.
The present invention's characteristic is that technology is simple, cost is very low, and its purposes is very extensive, can be applicable to every field such as civilian, medical, industrial, military affairs, has very high further researching value.
Concrete enforcement of the present invention is as follows.
Equably be blended in glass granules with the powder form magnetic substance according to a certain percentage, these magnetic substances comprise basic metal, transition metal and composition thereof and compound, then the mixture of magnetic substance and glass is heated to the two together and all is in the melt and dissolved state of liquid, magnetic substance under liquid state and glass have all been lost original solid-state molecule rule and have been arranged, the formation molecule of glass and the molecule of magnetic substance, atom or ion all mix mutually naturally with irregular thermal motion, be that magnetic substance is dissolved in glass and melts in the liquid, rapid for what dissolution process was carried out, thoroughly, tackling its mixing nothing continues to keep high temperature and stir fully, make the molecule of magnetic substance, atom or ion are dissolved in glass equably and constitute among the molecule, at last its mixed solution are carried out rapid cooling forming and make the hot glass of the magnetic with property.
Because magnetic substance and cloth can be lost its molecular magnetism because of being heated, so the glass made from this method also has certain magnetic except that the primary characteristic of keeping glass, the molecule of each magnetic substance, atom or ion are all surrounded by some glass molecules.Under the effect that external magnetic field is arranged, magnetic field will produce the effect of power to magnetic substance, this can be affected the glass molecule by intermolecular interaction again, as external magnetic field is an alternating electromagnetism ripple, magnetic substance in that glass just can produce corresponding vibration and affect its glass molecule on every side to vibrate with electromagnetic variation, intermolecular mutual collision, friction aggravation, the temperature of the hot glass of magnetic raises, and responds to the external electromagnetic ripple to hertzian wave generation absorption, shielding effect thereby its result shows as the hot glass of magnetic in the mode of self-heating.
In addition, magnetic substance itself just has temperature rising under the action of a magnetic field; Magnetic field is strong more, the physical phenomenon of many more " magnetothermal effect " heats up, this itself also is magnetic substance absorbs magnetic field energy with heating mode a characteristic, this specific character has improved the hot glass of magnetic to absorption of electromagnetic wave, shielding effect, especially for high strong electromagnetic wave, can certainly absorb, shield magnetostatic field energy.
The ratio that magnetic substance is sneaked in the glass can be divided unsaturated, saturated and several classes of supersaturation, it is different and different according to the purposes of the hot glass of magnetic, its concentration is big more, strong more to the absorption of electromagnetic wave function, the absorbent electromagnetic range of frequency of institute is also big more, can absorb, shield all hertzian wave from the long wave to the microwave.
The hot glass of this magnetic also can be realized wireless remote sensing heating defrosting with the windshield that the hot glass of this magnetic is made except that can be used as the transparent shield of general hertzian wave.The hot glass of this magnetic is further studied, improved its sensitivity, reduce the space electromagnetic pollution with it most probably, utilize the spatial strays magnetic wave that gives up electromagnetic wave induction.This can absorb the hot glass of highly sensitive magnetic the space hertzian wave and make a little higher than envrionment temperature of its temperature and eliminate the phenomenon that hazes under the microthermal climate.Make as method according to this and can absorb electromagnetic coating, then have purposes widely, also can be coated on the military target, be used to absorb high-strength microwave that radar sends as a kind of military cheaply " stealthy " means.
Claims (1)
1, the present invention is a kind of the absorption, the hot glass of the magnetic of shielding electromagnetic wave, it be according to a certain percentage with magnetic substance with powder form uniform mixing in glass granules, these magnetic substances comprise basic metal, transition metal and composition thereof and compound, then the mixture of magnetic substance and glass is heated to the two together and all is in the melt and dissolved state of liquid, then it is continued to keep high temperature and stir fully, at last its mixed solution is carried out rapid cooling forming and makes the hot glass of the magnetic with property, it is characterized in that magnetic substance is with molecule, atom or ionic form are blended in glass equably and constitute among the molecule, by the effect of magnetic field to the power of magnetic substance, mode with the common vibration of the molecule of magnetic substance and glass is responded to static magnetic field and hertzian wave, makes the hot glass self-heating of magnetic and absorbs, shielding external electromagnetic ripple and static magnetic field.
