Application of new permanent antistatic agent CNT in plastic field

In modern industrial production and daily life, static electricity hazards often cause Major losses and disasters, the main methods to prevent static electricity on the polymer surface include air ionization method, 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 Agents, etc. The main methods used in plastic products are to incorporate conductive substances and add PermanentAntistatic agent.

The added conductive material andPermanentAntistatic 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 kind of In the field of electronic packaging, the carrier tape has a specific thickness and is distributed along the length direction with “pockets” for holding electronic components, as well as positioning holes for indexing and positioning.

Generally in the actual production process, the carrier tape will be used together with the cover tape. Put resistors, capacitors, transistors, diodes and other electronic components in the “pocket” of the carrier tape, and use the cover tape to form a closed package, which can ensure Components are protected from contamination and damage during transportation.

Carrier tape is mainly used for surface mounting of electronic components and is currently widely used inIC, resistors, inductors, capacitors, connectors, fuses, switches , relays, connectors, oscillators, diodes and triodes and other electronic components.

The mainstream carrier tape materials currently on the market arePC, PS and ABS, etc. 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 Carrier tapes are generally required to have antistatic properties, so the carrier tape materials are mostly conductive plastics.

According to data,the number of global electronic devices will reach 3.31926 billion in 2020, and it is predicted that the market size of my country’s plastic carrier tapes will reach 12.35 billion meters , huge development potential.

2. Anti-static/conductive tray, used to eliminate Static electricity is widely used in the turnover loading, packaging, storage and transportation of electronic devices and product production processes.

The height of the tray is generally Containers below 100mm, suitable for the turnover and storage of precision electronic components. They are generally customized according to the requirements of customers’ electronic components. Requires good mechanical strength and heat resistance and…��Impact and corrosion resistance, it can effectively release the static 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.
