Explain ion fan classification
In addition to the numerous static electricity devices on the market, the types, styles, and prices vary, but they are divided into three major categories by operating modes: DC ion fan/AC ion fan/pulse ion fan.
1, DC ion fan
DC ion fan is called DC ion fan. For a single set of two needles, the discharge electrode is positive and negative. Taking a fan as an example, the discharge needle must be a double number. The wind bar is generally a double-row needle and can also be treated as a row of needles through a wire connection, but the discharge principle is the same. A single tip can only release a single positive or negative charge, and Needle tip loss is different, needle tip that releases positive static charge has faster loss, while needle tip loss that releases negative charge is slower. Ion imbalance is easily generated, and the positive and negative electrodes release charges at the same time, and are easily neutralized before reaching the surface of the object.
2. AC ion fan
AC ion blowers are called AC ion blowers and are the earliest working mode of removing static electricity. Similar products were produced as early as last year. Exchange can be understood as even if only one discharge needle can work normally. A discharge needle can switch positive and negative charges repeatedly. Because it is simpler, anyone can make a simple basic style, so the market is confusing and the method of distinguishing between good and bad is very simple. A good AC ion blower can touch the needle tip by hand, and will not cause harm to the human body. Because the charge discharged by the discharge needle is repeatedly switched, the service life is greatly increased compared to the direct current. The AC is divided into normal AC and high-frequency AC. It is determined by the discharge needle discharging the charge and the frequency of the transition between the positive and negative electrodes. The conventional ion fan is 50HZ to 60HZ per second, which is one second to release and work 50 to 60. The frequency of the release and switching of the high-frequency AC ion fan can reach more than 30,000 times. Compared with conventional ion fans, the charge ions of the high-frequency fan are not easy to neutralize and can cover longer distances.
3, pulse ion fan
Pulsed ion fans fall into many categories, which are listed below:
1. In pulsed DC and pulsed AC, the mode of operation is the same as above. The only difference is that both the DC double needle and the AC single needle work in the switching mode. When the positive charge is released, it will not Release negative charges and vice versa. However, there is a short pause in the switching process, so that the positive and negative charges are separated by a long distance, and the positive and negative charges neutralize the phenomenon, so that the product's coverage area can reach a longer distance.
2. ICC pulse refers to the release of positive and negative charges with the polarity of the protected product. It is also based on a single needle to switch positive and negative electrostatic charges to eliminate static electricity. The only difference is the bandwidth of positive and negative electrodes. Can be adjusted in real time, the proportion of positive and negative static content released will be changed according to the charge on the surface of the product.
3, MP pulse, also known as modulation pulse mode, theoretically the best mode to eliminate static electricity, using dual-frequency, there are basic large waveforms and high frequency of small waveforms, large waveforms according to the surface charge of the product to switch the bandwidth, Small waveforms are in high frequency switching and release to achieve better ion balance.
