Anti-static gloves principle and purchase precautions
The principle of anti-static gloves Anti-static gloves are gloves made of special materials, which can effectively place static electricity during use and protect the safety of workers. The material is usually made of conductive fiber material, and the spacing of the fiber gaps is designed according to the environment used. It is an indispensable product in the electronics industry.
There are coatings on the surface of the anti-static gloves to ensure the control of anti-static properties, which can be divided into the following two categories:
1. Using the principle of static dissipation to add relatively high-resistance carbon fiber to the glove, the advantage is that it is easy to wear, and it is more convenient for the person wearing the workpiece to operate the workpiece. The disadvantage is that the static dissipative stability is insufficient, and it is mostly used for conventional Used in the electronic assembly process.
2, using the grounding principle, the anti-static gloves weaving method is basically the same as the carbon fiber anti-static gloves, the difference is the use of low-resistance copper or silver fiber, which has the advantage of being able to remove static electricity from the human body. Thoroughly, the disadvantage is that the staff who use this kind of gloves also need to wear an anti-static wrist strap connected with the gloves. The operator must have a grounding device, which is relatively cumbersome to wear, and needs to ensure that the entire base is stable and unobstructed.
Brief description of the application of conductive fibers in anti-static gloves. Which anti-static gloves are mainly used in anti-static environments requiring gloves, such as: electronics, precision instruments, machinery manufacturing and other industries. Conductive fiber has good antistatic properties. It has been widely used in anti-static gloves and can meet the performance requirements of anti-static gloves.
Conductive fiber is a new type of fiber that appeared in the 1960s. It generally has a conductivity of more than 10-7 Ω-1. Cm-1 fiber. Such fibers have good electrical conductivity and durability, and particularly have good durable antistatic properties at low humidity.
The antistatic mechanism of the conductive fibers is to create a corona discharge between the conductive fibers. Corona discharge is a very gentle form of discharge. When the static voltage reaches a certain value, a non-sparking corona discharge is generated to eliminate static electricity. This phenomenon is generally considered to be the conductive fiber in the fabric. Under the action of the electrostatic field, the surrounding air is ionized to form positive and negative ions. One of the positive and negative ions is opposite to the static charge of the fabric and neutralized. The species is neutralized with the environment or the earth, thus eliminating static electricity. The significant difference between corona discharge and electrostatic leakage is that the former can eliminate the static electricity on the fabric without grounding, while the latter needs to be grounded or the static electricity can be eliminated when the air is large.
Qualified anti-static gloves can prevent the operator's fingers from directly contacting the electrostatic sensitive components, and can safely discharge the static charge of the human body brought by the operator, effectively avoiding the static electricity generated by the human body from causing damage to the product and preventing the electronic elements caused by static electricity. The device is damaged and aged. Therefore, the use of conductive fibers as a material for antistatic gloves is a mature antistatic technology.
What should I pay attention to when choosing anti-static gloves?
In the current production and life, the recycling of anti-static gloves is relatively small, although the normal maintenance of the finger-sleeve manufacturers will extend the service life of the gloves, but most of the operators now choose to change the gloves frequently. . Gloves are selected according to different environments and gloves with different characteristics, so as to achieve a win-win effect.
Anti-static gloves in the general raw material selection paste resin, the main role is to prevent certain electrical properties of transmission to ensure a certain degree of safety, the market supply is also slowly increasing, the supply is relatively tight.
Anti-static gloves can help operators stay away from harmful static electricity and slow down the discomfort caused by static electricity. The anti-static gloves are durable and easy to wash. Just wash them with water. ESD gloves are extremely effective and can quickly discharge static electricity, eliminating various static hazards. At the same time, it is also environmentally friendly, it is not easy to adhere to dust, and avoids secondary pollution in the clean room.
The choice of anti-static gloves should be combined with the basic characteristics of anti-static gloves. Here are some basic characteristics of gloves. According to the materials, they can be divided into cotton, plastic, plastic, latex, nylon, etc. It is a clean type, elastic type, breathable type, anti-static type, and the like. Anti-static gloves go through technical improvements to improve the performance of gloves, based on some special areas. With the emergence of new materials, the requirements of labor protection products continue to increase, the development of this paste resin provides a good opportunity, the requirements of new anti-static are constantly expanding, and the market has gradually matured.
