静电的危害和预防方法的例子)

1。之间的摩擦,从电力印刷纸和纸坚持麻烦打印页;潮湿的空气让静态很快消失。

2。人造纤维服装,穿着不多的努力将是一个覆盖了一层灰尘,风扇叶片旋转不长了灰尘,这是由于静电吸引一层厚厚灰尘的原因。

3。人们在地毯上行走,地毯摩擦可以产生超过100伏的高压,当双手被电击拉在手时,金属门,可把不锈钢丝在文件夹中的地毯进入静态地面,效果很好。

4。飞机在飞行中,在运输过程中因空气摩擦产生静电油罐车。当飞机降落时,静态地面人员将受伤;油轮已累积到了一定程度的静电放电会产生电火花,引起爆炸。油轮通过实地拖链,飞机上一坐轮通过静态地面到地下。

微小的静电放电可能引发瓦斯爆炸,造成的电击,会使人觉得产生了强烈的打击xx,或给予了高压静电会使人致命的。

部:事情总是“一分为二”,有消极的一面,但也可用于方,静态虽然有很多的危害,而且对物质文明和精神文明的分歧。目前,静电应用也很广泛。

答:
是任何一个国家内的一般收费,其收费的积极和消极的外部现象是相同数目的对象不是实况转播,但是当两个接触或摩擦,是一对象不同的对象负电荷的电子将跨越到另一个对象的接口,在增加静电。而且,由于他们对所带来的电荷积累当静电电压高时产生的两种不同电荷分离或联系人对象发生火花,这是静电放电现象。静态摩擦的主要原因,压电效应,归纳能力,吸附带电等。

What is static electricity hazard?

Question:
fall, winter, especially where dry hands a hit from anything will be electric, off Curtain / touch up radiator at once, sometimes other people’s clothes or hands touch the issue of what will be hit by sound of electricity !! at any time are “to” is simply too hard!!!
static in the end, what harm it? How can I reduce the static electricity in them?
Thank you, master / expert or have experienced comrades pointing in!!

Answer:
upstairs two masters to go into details, I also very easy to play “electric” person to talk about my approach and try to down the results were pretty good, want to help you:
( 1) In the interior basin of the regular release of water!
(2) try to wear cotton or wool clothes, reduce static electricity!
(3) with wooden comb hair, wash rinse was added during the first (not combo).
(4) drink plenty of water and fruit.
(5) after each shower and do not forget to wash hands after rubbing cream and hand cream.
As a result, not only to reduce static electricity, hair, skin and have a lot to improve the Oh!

Answer:
examples of static electricity hazards and prevention methods)

1. Friction between the printing paper from electricity and paper sticking to the trouble printing pages; humid air allows static to disappear soon.

2. Man-made fiber apparel, wearing not much effort will be covered with a layer of dust, rotating fan blades not long had a thick layer of dust, which is due to static electricity to attract dust reasons.

3. People walking on the carpet, and carpet friction can generate more than 1 volt high-pressure, when the hands are liable to pull electric shock when the metal door in hand may be in the carpet in the folder into the stainless steel wire into the static ground, works well.

4. Aircraft in flight, fuel tankers during transport due to air friction will produce static electricity. When the plane landed, the static ground personnel will be injured; tanker has accumulated to a certain level of electrostatic discharge will produce electric spark, causing an explosion. Tanker through the chains dragging on the ground, aircraft wheel on a ride through the static ground into underground.

tiny electrostatic discharge can cause gas explosion, caused by electric shock will make people feel produce cannabis with a strong blow, or gave very high voltage static electricity will make people fatal.

Division: things are always “one divides into two”, there are negative aspects, but also can be used side, static although there are many hazards, but also for material and spiritual civilization. At present the application of static electricity is also very broad.

Answer:
is any object with a charge within the general state, its positive and negative charges are equal number of external phenomena are not showing live, but when two different objects in contact or friction , an object with a negatively charged electrons will cross the interface into another object, the static electricity on the rise. And since they were brought about by the accumulation of charge occurs when a high static voltage generated when two objects with different charge separation or contact of a spark occurs, this is the phenomenon of electrostatic discharge. The main causes of static friction, piezoelectric effect, inductive power, adsorption, electrically charged and so on.

in the industrial and agricultural production, static electricity has a significant role, such as electrostatic flocking, electrostatic painting, electrostatic debugging, etc. Moreover, due to the presence of static electricity, but also tend to produce some hazards, such as electrostatic discharge caused by a fire accidents. With the rapid development of petrochemical industry, easy to produce static electricity more and more extensive use of the material, which also will increase the fire risk.

a fire risk
1. When the object generated by electrostatic charge piled up to form a high potential when charged objects with other non-contact, they will have a high potential difference, and discharge phenomena occur. When voltage is 300 volts or more, the resulting static spark can ignite surrounding combustible gas and dust. In addition, the static on industrial production there are certain hazards, but also harm the human body.

2, solid material in the transportation or production processes are subject to friction and squeeze a large area, such as the transmission of the friction between the belt and pulley; constant contact with the material under pressure, aggregation or separation; solid material in the extrusion, filtration with the pipe. Filter friction; of solid material in the crush. Grinding and mixing process and in other similar processes, can generate static electricity. Moreover, as the speed increases’ faster. The pressure increases, and friction. Contact surface when the squeeze is too large, air-drying and the equipment without a good grounding and other reasons, led to discharge electrostatic charge accumulation, there the fire danger.

3, flammable liquids generally have a greater resistance, in the filling, transport, transportation or production process, owing to mutual collisions, splash and wall friction or subject to shock, can generate static electricity. Especially when there is no conductive liquid particles, the inner surface rough pipeline, liquid flow rate too fast, you will have a very strong friction, electrostatic charge generated by I. In addition to static electricity when no sound device, then the accumulation of voltage discharge phenomenon occurred, very products could lead to fires.

4. Dust in the grinding. Mixing. Screening processes such as high-speed movement, so that between the dust and dust, dust and pipeline wall, vessel wall, or other apparatus, object collision and friction asked a lot of static electricity generated, ranging from impeding production, while in explosion.

5. Compressed gases and liquefied gases, because of containing liquid or solid impurities from the mouth or on broken pipe when the high-speed spray will strongly friction produce large amounts of static electricity, resulting in fire or explosion.

2, preventive measures
1. As pipelines, storage tanks. Filters, mechanical equipment, gas stations and other equipment can produce static electricity set a good grounding devices to ensure that static electricity generated by rapid import underground. Should pay attention to the installation of earthing, grounding devices and smoke where the liquid vapor to maintain a certain distance from the grounding resistance should be greater than 10 ohms, laying in the ground should not be brushing some anti-fouling paints. There is a strong corrosive soil areas, should be copper or galvanized grounding.

2. In order to prevent equipment and devices, equipment and piping between. Pipeline and the potential difference created between the container, in its connections, especially in the electrostatic discharge may cause burning of the site, with metal conductors connected together in order to eliminate potential difference, to achieve security. Of non-conductive pipe, shall, at its junction of the internal or external surface of winding metal line-tracking in order to eliminate potential difference between the components.

3, in the non-conductive or low conductivity material, the incorporation of conductive filler better performance, and anti-static agent, or in the material surface coated anti-static agent approach to increase its conductivity, and reduce its resistance, thereby eliminating the production of static electricity produced during the fire danger.

4. The location and intensity of reduce friction reduction and suppression of static electricity is also an effective way. If the gear, using triangular belt or direct shaft drive to reduce or avoid the area and intensity of flat belt friction generated too much static electricity is too large. Limitation and reduction of flammable liquids, combustible gases in the pipeline flow rate, can also reduce and prevent static electricity generation.

5. Check the dress high-pressure water vapor and flammable gas containers sealed to prevent the jet. Leakage caused by explosion, dumping, or perfusion flammable liquid, the application of air extending catheter along the vessel wall, or into the bottom of the output and the need to set some time in the net only after the sampling, measurement, filtering, mixing and other processing. At the same time, pay attention to beat gently, not use metal utensils are not grounded operation. Non-flammable liquid used as cleansing agents.

6. In a flammable and explosive hazardous production sites, should guard against equipment, containers and pipes leak, leak. Qin cleaning remove dust, enhance ventilation and other measures to reduce the flammable vapor. Gas. Dust concentration. Inflammable and explosive dangerous goods will not be allowed into the place is easy to produce static electricity.

7. Rotary fan sprayer can be used in the spray mist into the air and other methods, increasing the air relative humidity, increase air conductivity, prevent and reduce static electricity generation and accumulation. In a place where there is flammable and explosive vapors, spray mist should be outward-looking within the spray room.

8. In the flammable and explosive in high-risk place of work into the member should start by touching grounded metallic devices and other methods I. In addition to the human body brought about by static electricity, before entering. While avoiding the bud synthetic clothing and rubber-soled shoes with low electrical conductivity. In order to prevent static electricity produced by the body on fire in the inflammable and explosive places, and when the body is close to another high-voltage electric shock caused by physical injury.

9. Can generate static electricity discharge more places to install pin (electrostatic charge eliminator), so that the scope of the air discharge of free, the air became conductor, and in the accumulation of electrostatic charge can not be. However, the use of such devices should pay attention to take certain security measures, because of its higher voltage to prevent the assault.

10, to prevent and eliminate static electricity hazards approach are metal shield law (to be charged with an indirect metal body to shield conductors to prevent electrostatic charge caused damaged to the Human Body); inert gas protection law (to the transportation or storage of flammable . explosive liquids, gases and dust pipes, storage tank filled with carbon dioxide or nitrogen and other inert gas to prevent static spark caused by deflagration, etc.).05-11-09
