Precautions when using the deionized ion fan device
The anti-static device can be divided into two categories: AC and DC according to the high-voltage form used by the discharge electrode (discharge needle). , DC pulse type.
The difference between the AC and DC static elimination devices is that positive and negative air ions can be generated alternately on a discharge needle of the AC type. The discharge electrode is composed of the discharge needle and the grounding electrode. A ground electrode is required, and the discharge electrode consists of positive and negative discharge needles. When there is no external air supply (such as fans, compressed gas, etc.), the distance of the DC type eliminator is farther than that of the AC type. Structure, air volume and the strength of high-voltage power supply.
The difference between the AC and DC static elimination devices should be paid special attention to the difference in ion balance. The AC type static elimination device generates both positive ions and negative ions on the same discharge needle, so even if the discharge needle is worn out after long-term use, the ion balance will be lost. There will be no major changes, and the ion balance performance is better. Because the discharge needle is composed of independent positive and negative electrodes, the ion balance is poor when used in close proximity. In addition, the discharge needle is affected by the environment during use and the degree of pollution of the needle will affect the ion balance, especially the discharge. After the needle is used for a long time, the positive and negative discharge needles wear to different degrees, and the ion balance cannot be corrected even after cleaning.
Since the discharge needle will be polluted after long-term use, which directly affects the static electricity removal performance and ion balance, the static electricity removal electrode part should be cleaned regularly during use, especially the DC type discharge needle is more susceptible to pollution. Electrical appliances should be cleaned more frequently, and the positive and negative discharge needles have different degrees of wear, so regular ion balance testing is required. When the discharge needle is seriously worn, the discharge needle should be replaced in time.
