Abstract: |
On the basis of analyzing microwave on the surface polarization effect of crystalline materials, the micro-mechanism of how microwave catalytically silver strip materials is carefully studied, and this thesis finds that: (1) In the microwave field, the local resonance coupling is happened between microwave and both of silver weak-bond surface and defect position, and forms the "microwave hot spots" where it is the active site to cause sulfide corrosion. (2) Electric dipoles, caused by the microwave in reaction system, can rapidly rotate and make the "sensitive agent" transfer absorbed microwave energy to the silver strip lattice, so as to increase the reaction rate of silver strip corrosion. (3) Silver sulfide, formed by silver strip and active sulfur in jet fuel, has the covalent components, and acts more weakly with microwave, and is unable to react continuously, so that the corrosion reaction spreads out to other position, and the reaction sites to form silver sulfide continually expand.
