Application of carbon black viscosity reducing dispersant and issues that need to be noted
in the application
Carbon black viscosity reducing dispersant is widely used in many fields. At the same time, some
issues need to be noted in the application process. The following is a detailed description of these
two aspects:
1. Application of carbon black viscosity reducing dispersant
Carbon black viscosity reducing dispersant is mainly used in occasions where it is necessary to improve
the dispersion effect of carbon black and reduce the viscosity of the system, including but not limited to:
Coating industry: Adding carbon black viscosity reducing dispersant to the coating can significantly improve
the dispersion uniformity of carbon black and reduce the viscosity of the coating, thereby improving the fluidity
and construction performance of the coating.
Plastic industry: Adding carbon black viscosity reducing dispersant to plastic can effectively improve the dispersion
effect of carbon black in plastic, reduce the melt viscosity of plastic, and improve the processing performance and
mechanical properties of plastic.
Rubber industry: Adding carbon black viscosity reducing dispersant to rubber can improve the dispersibility of carbon
black in rubber, reduce the viscosity of rubber, and increase the vulcanization speed of rubber and the physical properties
of vulcanized rubber.
Ink industry: Adding carbon black viscosity reducing dispersant to ink can improve the dispersion uniformity of carbon black,
reduce the viscosity of ink, and improve the printing performance and drying speed of ink.
2. Issues that need to be paid attention to during application
Selection of dispersant: The appropriate carbon black viscosity reducing dispersant should be selected according to the specific
application field and the type of carbon black. Different dispersants may have different dispersion effects on carbon black and the
degree of reduction of system viscosity.
Dosage control: The amount of carbon black viscosity reducing dispersant should be determined according to the content of carbon
black and the viscosity requirements of the system. Too much dispersant may cause excessive reduction of system viscosity and affect
the performance of the product; while too little dispersant may not achieve the expected dispersion effect.
Dispersion process: After adding carbon black viscosity reducing dispersant, appropriate dispersion process, such as stirring, grinding,
etc., should be adopted to ensure that carbon black is fully dispersed in the system. At the same time, parameters such as temperature
and time during the dispersion process also need to be strictly controlled.
Environmental protection and safety: Carbon black viscosity reducing dispersant should comply with relevant environmental protection and
safety regulations during use. Avoid direct contact with skin and eyes. Operate in a well-ventilated environment and wear necessary protective
equipment. Dispose of waste properly after use to prevent environmental pollution.
Compatibility with other additives: When adding carbon black viscosity-reducing dispersant, pay attention to its compatibility with other additives.
Avoid chemical reactions with other additives, which may lead to product performance degradation or the production of harmful substances.
In summary, carbon black viscosity-reducing dispersants are widely used in many fields, but during the application process, attention should be
paid to the selection of dispersants, dosage control, dispersion process, environmental protection and safety, and compatibility with other additives.
Through reasonable application and management, the advantages of carbon black viscosity-reducing dispersants can be fully utilized to improve
product performance and quality.
