Antistatic agent is an additive that can be added to paint, plastic, rubber and other materials to improve the antistatic performance of the material. Antistatic agents can absorb or release electrons, thereby preventing or reducing the accumulation and discharge of static electricity, and effectively avoiding problems such as fire, explosion, and adhesion caused by static electricity. Antistatic agents are mainly used in materials and equipment that have strict requirements on static electricity in the fields of electronics, medical treatment, and chemical industry. Commonly used antistatic agents include ionic, nonionic and conductive types, and different antistatic agents can be selected for addition according to different needs.
Detection performance
The following are some common antistatic agents and their properties that need to be tested:
| antistatic agent | Detection performance |
|---|---|
| Ionic antistatic agent | Antistatic performance, electrical conductivity, dispersion performance, stability performance, PH value, ionicity, etc. |
| Non-ionic antistatic agent | Antistatic performance, dispersion performance, stability performance, PH value, etc. |
| Conductive antistatic agent | Antistatic performance, electrical conductivity, dispersion performance, stability performance, PH value, etc. |
The properties that need to be tested for antistatic agents include antistatic properties, electrical conductivity, dispersion properties, stability, pH value, ionicity, etc. The specific detection methods can be determined according to different types of antistatic agents and specific requirements. For example, for ionic antistatic agents, an ion chromatograph can be used to measure ionicity and pH value; for conductive antistatic agents, a resistivity meter can be used to measure conductivity; for dispersion and stability performance, dynamic light Scatterometer and UV-Vis Spectrophotometer and other instruments to detect.
Detection method
The following is a brief introduction to the detection methods of some common antistatic agents:
Antistatic performance testing: Antistatic performance testing is generally carried out using a resistivity meter or a surface resistance meter. A resistivity meter can measure the resistivity of a material, while a surface resistivity meter can measure the resistance value of the surface of a material.
Conductivity test: The test of conductivity requires the use of a resistivity meter or a conductivity meter. A resistivity meter measures the resistivity of a material while a conductivity meter measures the electrical conductivity of a material.
Dispersion performance testing: The dispersion performance testing can be carried out using a dynamic light scattering instrument. The instrument can measure the particle size and dispersion of materials.
Stable performance test: The test of stable performance can be carried out using a UV-visible Spectrophotometer . The instrument measures the absorption and transmission of materials to assess their stability properties.
PH value detection: PH value detection can be carried out using a pH meter. A pH meter is an instrument for measuring the pH of a solution.
Ionic degree detection: The detection of ion degree can be carried out by ion chromatograph. An ion chromatograph separates and detects ions in solution to measure their ionicity.
NBCHAO reminds you: the specific detection method may be slightly different due to different antistatic agent types and specific requirements, so when performing detection, it is necessary to select the appropriate instrument and method according to the specific situation. At the same time, in order to ensure the accuracy and reliability of test results, standardized operations and strict quality control are also required.
