For the filtration of ink products, the following are clear steps and considerations, combined with relevant numbers and information from reference articles:

1. Determine filtering requirements

Particle size: First, determine the size of the impurity particles that need to be removed. This is usually based on the application field of ink and the requirements for printing quality.

Filtering accuracy: Select the appropriate filtering accuracy based on particle size. For example, small ink filters can provide different filtration accuracies from micrometer to submicron levels.

2. Choose the appropriate filtering method

Screen filtration: Use a precision metal screen to filter ink and remove impurities from large particles. This method is easy to operate and cost-effective, but it may not fully meet high-precision requirements.

Magnetic filtration: suitable for removing ferromagnetic impurities. If the ink contains such impurities, this method is effective.

Ultrasonic filtration: By using high-frequency ultrasonic vibration to remove impurities from ink, it can filter more thoroughly. But the operation is more complex and the cost is higher.

3. Consider the usage conditions of the filter

Screen aperture: Select the appropriate screen aperture based on the particle size of the ink to ensure effective filtration.

Material compatibility: Use materials compatible with ink to manufacture filters, such as stainless steel, polypropylene, etc., to avoid contaminating ink or chemical reactions.

4. Installation and maintenance of filters

Installation: Ensure that the filter is installed in accordance with operating standards and securely fixed to prevent ink leakage.

Cleaning and replacement: Regularly clean and replace the filter to maintain its filtering effect. When using ink filter bags, it is also important to avoid ink solidification.

5. Selection and optimization of filtration system

Fully automatic cleaning system: For large ink filtration systems, a fully automatic cleaning system can be selected to reduce manual operation and improve efficiency.

Solution circulation spray: Through filtering media such as filters, activated carbon, and reducing resin, the solution is circulated and filtered to ensure comprehensive cleaning without dead corners.

6. Precautions

Avoid excessive filtering: Excessive filtering may increase costs and reduce production efficiency, so it is necessary to choose the appropriate filtering accuracy according to actual needs.

Safe operation: When operating filtering equipment, it is necessary to follow safe operating procedures to ensure the safety of personnel and equipment.

7. Verification of filtering effect

In practical applications, the filtering effect can be verified by visual inspection, weighing method, or particle counter to ensure the effective removal of impurities in the ink.

In summary, for the filtration of ink products, it is necessary to comprehensively consider multiple aspects such as filtration requirements, filtration methods, usage conditions, installation and maintenance, system selection and optimization, and precautions. By selecting appropriate filtering methods and equipment, and following correct operating and maintenance procedures, the quality of ink and printing effect can be ensured.
