What are the precautions and restrictions for using water-based carbon black dispersants?

When using water-based carbon black dispersants, the following precautions and restrictions should be noted:

I. Precautions

Contact and protection of chemicals:

Avoid direct contact: Water-based carbon black dispersants may contain ingredients that are irritating to the skin and eyes, so direct contact should be avoided as much as possible during use. If contact is necessary, wear appropriate protective gloves and goggles.

Respiratory system protection: Dust or volatile organic matter may be generated during use, which may cause harm to the respiratory system. Therefore, it should be operated in a well-ventilated environment and wear a dust mask or gas mask.

Storage safety:

Water-based carbon black dispersants should be stored in a cool, ventilated, and dry warehouse, avoiding direct sunlight and high temperature environments.

It should be stored separately from oxidants, acids and other substances to prevent chemical reactions.

Prevent leakage:

During use, ensure that the container of water-based carbon black dispersants is well sealed to prevent leakage.

If leakage is found, measures should be taken immediately to isolate and handle it.

Emergency treatment:

If an accident such as leakage or fire of water-based carbon black dispersant occurs, the emergency plan should be activated immediately, personnel should be evacuated, fire sources should be cut off, isolation measures should be taken, and professional rescue teams should be contacted for treatment.

Health monitoring:

People who have long-term contact with water-based carbon black dispersants should undergo regular health examinations to detect and deal with health problems in a timely manner.

Environmental protection:

When using water-based carbon black dispersants, pollution to the environment should be minimized.

Waste after use should be handled in accordance with relevant regulations to prevent long-term impact on the environment.

II. Restrictions

Choose a suitable dispersant:

Different water-based carbon black dispersants are suitable for different types of carbon black and different application scenarios. Therefore, when selecting and using, it is necessary to make a comprehensive consideration based on the specific application requirements and the properties of carbon black.

Addition method and dosage:

A suitable addition method must be selected because the water-based dispersant is added to the system. If it is not ground or dispersed at high speed, the ideal dispersion effect will not be achieved.

Pay attention to the dosage of water-based dispersant. If the dosage is not enough, the cohesion between the particles will affect the gloss and viscosity, and affect the final coloring effect.

Compatibility:

The dispersant and the resin system need to have good compatibility, otherwise the dispersed pigment particles are easy to flocculate, thus affecting the evaluation of its blackness.

Operation specification:

When using water-based carbon black dispersants, the operating procedures and safety regulations should be strictly followed to ensure the safety and effectiveness of the operation process.

In summary

When using water-based carbon black dispersants, it is necessary to pay attention to multiple safety issues and follow certain restrictions. Only by ensuring that these safety measures and restrictions are implemented can the safety and environmental protection of the production process be guaranteed, while obtaining the ideal dispersion effect and product quality.
