一定要知道的空气净化工程防护五要点

结合空气净化工程的概念及工作中积累的一些经验,现在从人、机、法、料、环五个方面来谈谈ESD的防护。
 
Combined with the concept of air purification project and some experience in the work, now from the people, machines, methods, materials, five aspects of the aspects of the protection of the ESD.
 
(一)人。人体可以说是一个高静电源,人体静电的防护,借助的是屏蔽及释放静电。严格来说要求做到“全副武装”,即:要戴防静电工帽、防静电口罩、防静电手套、指套等, 要穿防静电服、防静电鞋,同时还要戴上手腕带等来屏蔽及导走静电。总之,尽量不要让人的皮肤外露。
 
(a) person. Human body can be said to be a Gao Jing power, the human body electrostatic protection, with the help of the shielding and release of static electricity. Strictly speaking requirements to achieve "heavily armed", namely: to wear anti static cap, anti static mask, anti-static gloves, fingerstall, to wear anti-static clothing, anti-static shoes, also will have to wear wrist belt to shield and guide the electrostatic. In short, try not to let people's skin exposed.
 
(二)机器。机器也是一个高静电源,因为机器机械部件,特别是马达等,易产生EMI(电磁感应),所以对机器静电的防护,也是非常必要的。对于机器静电的防护,一般通过电磁场的消除、高静电部位的屏蔽、机器接地等来实现。一般消磁借用的是消磁器,消除电荷用的是离子风机。当电磁场无法消除或较难消除时,我们就借助静电屏蔽设备来屏蔽高静电设备或设备的高静电部位,比如,马达,大家都知道,马达易产生EMI,但机器要运转又离不开马达,所以,不防把它屏蔽起来。还有工作台、电源线、电脑键盘等,都可以接用静电屏蔽的方法来做ESD防护,这方面可用的屏蔽产品有防静电台垫、防静电薄膜、防静电帘、防静电屏蔽袋、防静电胶带等。最后,不管机器屏蔽或消磁效果如何,给机器接上ESD地线是很必要的。
 
(two) machine. The machine is also a Gao Jing power supply, because the mechanical parts, especially motors, etc., are easy to produce EMI (electromagnetic induction), so the protection of the machine's static electricity, but also very necessary. For the protection of the machine static electricity, the electromagnetic field is eliminated, the high static electricity parts of the shield, the machine to achieve. General degaussing is borrowed from the demagnetizer, eliminate the charge with the ion fan. When the electromagnetic field can not be eliminated or more difficult to eliminate, we have the use of electrostatic shielding equipment to shield high static electricity equipment or equipment, such as motors, we all know, Ma Dayi produced EMI, but the machine to operate and can not be separated from the motor, so it is not shielded. There are working table, power line, computer keyboard, etc., can be used to do ESD shielding method, which can be used to protect the shield products, anti-static pad, anti-static film, anti-static curtain, anti-static shielding bags, anti-static tape, etc.. Finally, no matter how the machine or machine to shield demagnetizing effect, connected the ESD wire is very necessary.
 
(三)料。即材料。如果产品对静电很敏感,那么生产线上是不能有高静电材料出现的,特别是离产品较近的区域,要尽可能用防静电材料,比如元件盒、货架、工作台、运输设备、清洗设备、化学试剂等,甚至连用的笔及笔记本都要用防静电笔及笔记本,因为在您用笔时,它有可能会接触产品。当然,如果产品对静电敏感程度不是很高,可以酌情处理,但最好借助ESD实验来证明一下,看看是否真的可以放心。
 
(three) data. Material. If product is sensitive to static electricity, so the production line is not high electrostatic materials, especially the region closer to the product, as far as possible with anti-static materials, such as component boxes, shelves, such as working platforms, transportation equipment, cleaning equipment, chemical reagent, even even with pens and notebooks to anti-static pens and a notebook, because when you write with the pen, it is possible to come in contact with the product. Of course, if the product is not very sensitive to static electricity, can be appropriate, but it is best to use ESD experiments to prove that you can see if you can rest assured.
 
(四)环。即工作区域的环境。一个良好的防静电的工作环境对于生产来说是很重要的。
 
(four) ring. Working area environment. A good anti - static working environment is very important for production.
 
(五)法。谈起方法,首先要明确以上四点,其实法就是建立合理的方法及规范以保证以上四点有效实现。另外,当产生ESD原因不能明确时要根据生产工艺,设计相应的ESD实验,来仔细查找产生ESD问题的原因。最终要建立相应的ESD操作规程及纪律规范来规范生产。
 
(five) method. Talking about methods, we must first clear the above four points, in fact, the law is to establish a reasonable method and specification to ensure that more than four points. In addition, when the ESD reason can not be clearly defined according to the production process, design the corresponding ESD experiment, to look for the reasons for the problem of generating ESD. Finally to establish the corresponding ESD operating rules and discipline to regulate production.
 
当然, http://www.jnjkjh.com/ 防护系统建立起来以后,对于工作人员来说,所要做的是经常检测这个系统,以不断的发现有不完善的地方,并做相应的改善,以保证系统长期有效的维持其ESD的防作用。这样,建立相应的ESD职能部门,并不断的培养其专业技能,提高其ESD防护意识,也都是空气净化工程防护中不可缺少的一部分。
 
Of course, air purification engineering protection system after the establishment of the staff, the need to do is to regularly test the system, in order to continue to find imperfect place, and to make the corresponding improvement, in order to ensure that the system is effective for the long-term maintenance of its anti ESD effect. In this way, the establishment of the corresponding functional departments of the ESD, and continue to develop their professional skills, improve their ESD protection awareness, but also an indispensable part of air purification engineering.
