In modern industrial production and daily life, static electricity hazards often cause heavy losses and disasters. The main methods to prevent static electricity on polymer surfaces include air ionization, Humidification method, metal contact discharge method, radiation method, conductive substance introduction method, surface formation of hygroscopic film method, chemical treatment denaturation and application of antistatic agent, etc. Among them, the main methods used in plastic products are to incorporate conductive substances and add permanent antistatic agents.
The added conductive substances and permanent antistatic agents are generally metal powder and metal short fibers, carbon nanotubes (CNT), conductive carbon black, conductive polymer short fibers etc., which can make the products have good conductivity or antistatic properties. Carbon nanotubes have good conductive and antistatic effects and are continuously effective. Application of conductive plastics;
1. Electronic carrier tape is a tape-shaped carrier used in the field of electronic packaging. The carrier tape has a specific thickness and is distributed in the length direction. There are “pockets” for holding electronic components, and positioning holes for index positioning.
Generally, in the actual production process, the carrier tape will be used together with the cover tape. Placing resistors, capacitors, transistors, diodes and other electronic components in the “pockets” of the carrier tape, and using the cover tape to form a closed package, can ensure that the components are not contaminated and damaged during transportation.
Carrier tape is mainly used for surface mounting of electronic components. It is currently widely used in ICs, resistors, inductors, capacitors, connectors, fuses, switches, relays, Plug-ins, oscillators, diodes and triodes and other electronic components.
The mainstream carrier tape materials currently on the market are PC, PS and ABS. Due to the diversification of sizes, shapes, and functions of electronic components, the requirements for carrier tape materials are also constantly increasing. Carrier tapes are required to have good mechanical properties, dimensional stability, temperature resistance, antistatic and many other requirements.
Electronic components are generally very sensitive and easily damaged by static electricity. This requires that the carrier tape generally has anti-static properties, so the carrier tape material is mostly conductive plastic. .
According to data, the number of global electronic devices will reach 3.31926 billion in 2020, and the market size of my country’s plastic carrier tapes is predicted to reach 12.35 billion meters, with huge development potential .
2. Anti-static/conductive pallets are used to eliminate static electricity and are widely used in the turnover loading, packaging, storage and transportation of electronic devices and product production processes. .
The height of the pallet is generally below 100mm. It is suitable for containers for the turnover storage of precision electronic components. It is usually customized according to the requirements of the customer’s electronic components. It is required to have good mechanical strength and heat resistance, as well as impact resistance and corrosion resistance. It can effectively release the electrostatic charge accumulated on the surface of the object without generating charge accumulation and high potential difference, so as to reduce the damage rate of electronic products during the production process.
