What are the common anti-static products on the market
In many of our industrial productions, the presence of static electricity will affect our work process, and if it is serious, it will also affect the quality of the products produced, so at this time we must take anti-static measures. There are many anti-static products on the market in our country. We can choose according to our work needs and personal preferences. Let the anti-static rubber sheet manufacturers introduce us to several common anti-static products. Right.
Various styles of anti-static clothing
There are many styles of anti-static clothing. According to the picture style, the anti-static work clothes can be divided into: anti-static coveralls and anti-static gowns; there are several different styles of anti-static coveralls, which can be customized according to customer requirements; anti-static The gown mainly has two styles: suit collar and stand-up collar; anti-static work clothes are divided by fabric: 100D, 75D and 68D. Among them, 100D is more commonly used.
Anti-static work clothes are divided by color: There are many choices, based on the fabric version of Chuangxuanbao. The anti-static clothing produced by Chuangxuanbao is made of special anti-static clean fabrics. This fabric is made of special polyester filaments, and the Belltron9R series conductive fibers of Japan Kanebo Co., Ltd. are interwoven in warp or weft direction. It has the characteristics of high-efficiency and permanent anti-static and dust-proof performance, thin and smooth, and clear texture. In the process of making garments, special overlock machines are used to effectively reduce the generation of particles. The dust-free hook and loop tape avoids polluting the environment due to hair loss. Different styles are provided according to the requirements of the level, and conductive fiber is used to sew all parts of the garment to maintain electrical continuity; the sleeves and trousers have a unique double-layer structure, and the inner layer uses conductive or anti-static ribs to meet the requirements of high-level dust-free environments . Anti-static shoe cover
The anti-static shoe cover fabric is 5mm striped or grid anti-static fabric. The colors of the fabric are: white, blue, navy blue, etc., which can be used repeatedly after washing. It is more economical and more practical than disposable shoe covers. Suitable for high clean and dust-free environment, this product can be adapted to 10-10000 dust-free environment.
The anti-static shoe cover has better anti-static and dust-proof effects. The anti-static index can reach the 6th power of 10 to the 9th power of 10, and the friction voltage can be controlled within 100 volts, which can prevent the static electricity of the human body from affecting ESD sensitive devices. Damage and prevent dust from escaping from the bottom of the shoe to pollute the dust-free workshop.
Scope of application of anti-static shoe covers: general electronics industry, LCD manufacturing, pharmaceutical product manufacturing, semiconductor industry, magnetic head manufacturing, chip manufacturing, optics, wafers and other production areas that require ESD and purification levels.
Anti-static wrist strap style
Anti-static wrist straps are divided into corded wrist straps, cordless wrist straps and smart anti-static wrist straps. According to the structure, they are divided into single-loop wrist straps and double-loop wrist straps. They are used to discharge static electricity from the human body. It consists of elastic band, movable snap button, spring cord. It is composed of protection resistor and plug or chuck. The inner layer of the elastic band is woven with antistatic yarn, and the outer layer is woven with ordinary yarn.
main indicators
The maximum length of the spring cord is 250cm, and the leakage resistance is 106Ω (protection resistance 106Ω). Detailed introduction of the anti-static wrist strap The wireless electrostatic wrist strap is developed based on the physical principle of (static voltage balance), based on the principle of "In Electrostatic Engineering" that static electricity is transferred by pushing between ions. The feature of pushing from the static electricity from the high voltage to the high potential pushes the human body's electrostatic ions into the drought body design (collection area), through the [charge induction principle], the front and back surfaces of the conductive plate will be charged with "equal opposite charges" -Skin effect, due to the built-in ion exchanger <utilizing its low free energy characteristics>, it can easily provide the introduced electrostatic ions with the same amount of opposite charge to neutralize, so the effect of electrostatic discharge can be achieved. There is a screw on the outside, which is connected to the internal conductor loop (1) It can be used as a high static power source due to improper touch by personnel, causing a large amount of electrostatic charge to be introduced instantly. When the ion neutralization is not complete, it can be provided by the external air water molecules through the screw Ion neutralization (for the Corona discharge effect), effectively eliminates static electricity, and achieves the ultimate goal of static discharge (static voltage balance). (2) This screw can be used for potential zero return function (just touch the screw to the ground), (3) It can be used as a loop detection terminal.
Wired grounding wrist strap is the most basic of anti-static equipment, and it is also a must-have for the most commonly used production line. It is not only very convenient in erection and operation, but also the most affordable in price. The reason is that it is through the wrist strap and grounding The wire discharges the static electricity on the human body to the ground. Therefore, the wrist strap must be in contact with the skin when using it. The grounding wire must also be directly grounded. Ensure that the grounding wire is unobstructed in order to achieve maximum effect.
Anti-static wrist strap with static ring
A device that is worn on the wrist of the human body to discharge the accumulated electrostatic charge of the human body. It is divided into a wired type and a wireless type, with a metal ring and a mixed ring of elastic conductive wire. This product belongs to one of the anti-static wrist straps with buckle adjustment wired type, which can effectively protect the zero resistance parts from the interference of static electricity, and discharge the static electricity of the human body. It is composed of anti-static elastic band, movable snap buckle, spring cord, protective resistor and chuck. The inner layer of the elastic band is woven with antistatic yarn, and the outer layer is woven with ordinary yarn. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the earth through the wrist strap and the grounding wire. When in use, the wrist strap is in contact with the skin, and the grounding wire is directly grounded, so that it can exert its maximum effect. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body within 0.1 seconds. The grounded wrist strap is the most basic anti-static equipment and the most commonly used.
