Spiral waveform vibration ion engine
The invention discloses a spiral waveform vibration ion engine. A shell, an insulation heat insulation layer, a coil heating layer, a first insulation layer, an electrode cavity, a second insulation layer and a magnetic field generation rod are sequentially arranged from the outermost layer to the innermost layer of the ion engine. The electrode cavity sequentially comprises an electrode cavity outer ring, a third insulating layer, a fourth insulating layer and an electrode cavity inner ring from outside to inside; a propellant is filled between the third insulating layer and the fourth insulating layer; and two poles of the coil heating layer, the outer ring of the electrode cavity, the inner ring of the electrode cavity and two poles of the magnetic field generating rod are electrically connected with an alternating current power supply. The spiral waveform vibration ion engine has the beneficial effects of high efficiency and large thrust-weight ratio; cleanness and no carbon emission are realized; according to different properties of the carrier, the engine can select different metals, liquid metals or strong electrolytes as propellants; the engine can be designed to be cylindrical, disc-shaped or ring-shaped according to different shapes of carriers; and energy is saved, and long-time use can be achieved by one-time propellant filling.

The invention discloses a preparation method and an application of an environment-friendly hot melt adhesive having low initial adhesion and no compression sensitivity after curing and used for a disposable sanitary material. The hot melt adhesive is prepared from 10%-25% of naphthenic oil, 15%-35% of a macromolecular polymer, 1%-10% of synthetic wax and 0.1%-1.0% of an antioxidant. The inventionmainly aims to provide the environment-friendly hot melt adhesive which is used at four end seal parts of the disposable sanitary material, is not carbonized, has excellent bonding property, low initial adhesion, no compression sensitivity and low odors, continuous production of a production line can be guaranteed, the repair and maintenance costs of equipment can be reduced, and 10%-30% of production cost can be saved as compared with a traditional SBC formula hot melt adhesive. The hot melt adhesive overcomes the defects of high initial adhesion and high compression sensitivity of hot melt adhesives after curing in the prior art. The hot melt adhesive reduces initial adhesion and compression sensitivity of the hot melt adhesive after curing by use of a novel host material at four end seal parts of the disposable sanitary material.
