摘要:
A high voltage gap discharge switch is provided with a pair of sphere electrodes 1, projections 2 and a blower 5. The sphere electrodes 1 are separated by a discharge gap and oppose each other. The projections 2 are provided integrally at the mutually facing tips of the sphere electrodes 1, and have a projection length of 1/100 to 1/8 times the diameter of the sphere electrodes 1 and an outer diameter of 1/100 to 1/10 times. The blower 5 gives rise to an air current for expelling products produced on the projections 2 due to the generation of a spark discharge. The blower 5 supplies air to the discharge gap at a wind speed of 0.5 to 25 m/sec.-KW. One objective of the present invention is to stabilize the wave-form of a high voltage pulse and to increase its durability using a simple construction.

The plasma generating apparatus (1) is provided with a simple switching circuit (3) for generating AC power of high frequency by a magnet (16) for switch driving use for repeating the excitation and the demagnetization by AC power and a contact switch (S) to be opened or closed by the magnet (16), a simple voltage transforming circuit (4) for converting AC power of high frequency outputted from the switching circuit (3) into AC power of high voltage, a discharge electrode (5) for receiving AC power of high frequency and high voltage outputted from the voltage transforming circuit (4) to cause corona discharging, when the opposite electrode has been approached, to cause the plasma. The plasma producing apparatus (1) is easier to be carried, because the switching circuit (3), the voltage transforming circuit (4), and the discharge electrode (5) are respectively simple, compact in construction. The apparatus (1) becomes smaller in power capacity and is reduced in cost.
摘要:
Present invention provides a process for corona discharge treatment, which improves more efficiently the plastic surface having poor wetting properties, particularly the surface of a molded material having various shapes. The plastic surface is treated with a corona discharge generated by a high-voltage pulse while blowing a gas.
