Antistatic agent is not suitable for all products
Antistatic agent is a simple, convenient and fast antistatic method, which is added on the surface or inside of the insulating material to reduce the ability of static electricity. However, the use of antistatic agents is also limited. E.g:
Antistatic agents can be applied to floors, carpets, worktop tops, parts carriers, chairs, walls, ceilings, tools, paper, plastics and skins by brushing, spraying, rolling, dipping, rubbing or other methods. They become ESD protection objects to varying degrees. Some antistatic agents are also good scavengers that can be mixed with water to clean surfaces like the floor and the top of the table, while turning them into antistatic.
However, antistatic agents are not suitable for use in circuit boards, parts or assemblies because such antistatic agents increase electrical conductivity and may affect weldability. At the time of the cleaning operation, the antistatic agent is removed, and the surface after cleaning may need to be disposed of from the beginning. The anti-static supply protection period depends on the resistance of the material such as the usual polyethylene, and then the potential is measured by an electrostatic field meter and its decay time, or the surface resistivity of the material sample is measured with a suitable device. ESD protective materials that require punctual disposal with an antistatic agent, with a label indicating the date on which ESD protection should be checked from the beginning. These items can include shipping buckets, trays and protective gloves.
In addition, it is also necessary to pay attention to the characteristics to be considered when selecting an antistatic agent. In addition to its antistatic properties, it also includes: prohibiting bacterial growth; non-toxic; non-corrosive; non-irritating to humans.
