The reason why the ion fan chooses tungsten discharge needle
Tungsten needle is simply a kind of commodity butt tungsten metal, with excellent physical and chemical properties, has become one of the most popular electroacupuncture today.
Discharge needle is one of the most important parts in ionic fan. In addition to the long-term work after air pollution will harm the centrifugal fan to eliminate electrostatic expected effect and covalent bond balance, its product quality will also harm the centrifugal fan at the same time in addition to the electrical performance. At present, the more widely used electroacupuncture is stainless steel plate needle and tungsten commodities. Relative to tungsten electroacupuncture, although the stainless steel plate needle has the advantage of lower price, but its wear resistance, oxidation resistance and corrosion resistance are less than tungsten electroacupuncture.
The office environment of electroacupuncture is relatively extreme. Generally speaking, it is to be promoted to 4kV or some higher standard working voltage (2-3kV high frequency AC method), so the front part of the discharge needle must bear a very large mechanical load, which is the key reason for the easy damage of the goods and short cycle time.
In view of the above problems, today's manufacturers want to choose organic compound metal tungsten as the discharge needle of ion fan. Tungsten is a silicified metal material, melting point in the middle of 3390°C-3430°C, and it made of needle end goods not only has good high temperature resistance, wear resistance and analytical chemical stability, It also has the advantages of excellent conductivity, high tensile strength, relatively large compressive strength, no radioactive substances and more friendly to ecological environment management.
Therefore, compared with stainless steel plate, tungsten needle is more suitable for discharge needle, which can not only ensure a longer service period, but also make the related centrifugal fan eliminate electrostatic effect is stronger, and effectively improve work efficiency. Need to say very is, the making raw material that puts electric needle also is to have metallic material to pledge germanium, nickel, titanium to wait for raw material.
