How to improve the ink adhesion of wax based carbon tape?

To improve the ink adhesion of wax based carbon tape, you can start from many aspects, the following are some specific methods and suggestions:

First, choose the right ink

1. Ink and substrate matching:

Ensure that the wax based carbon strip ink and substrate material have good adaptability. Different substrate materials have different surface properties, and it is necessary to choose an ink that can be well combined with it.

For wax-based carbon strips, it is usually necessary to consider the adhesion performance of ink on plastic, paper and other materials.

2. Ink quality:

Use high quality inks and avoid out-of-date or poor quality inks that may have poor adhesion.

Second, optimize the ink formula

1. Adjust the composition ratio:

Adjust the ratio of viscosity, resin, pigment and other components in the ink as needed to improve the adhesion of the ink.

The appropriate viscosity helps the ink to form a uniform coating on the surface of the substrate material and improve the adhesion effect.

2. Add specific chemicals:

By adding coupling agents, crosslinking agents, plasticizers and other chemicals, the binding force between the ink and the substrate can be enhanced.

These additives can improve the wettability of the ink and promote the penetration and adhesion of the ink on the surface of the substrate.

Third, improve the surface properties of the substrate material

1. Surface treatment:

The surface of the substrate material is cleaned and polished to remove oil, paraffin, silicone oil and other release agents and silicone auxiliaries to improve surface tension and roughness.

Surface treatment can increase the contact area and friction between the ink and the substrate material, thereby improving the adhesion.

2. Pre-primer:

A layer of primer oil or treatment agent is pre-coated on the surface of the substrate material, which can improve the tension on the surface of the material and help the ink adhere better.

Fourth, optimize the printing process conditions

1. Printing pressure:

The appropriate printing pressure can make the ink better transferred to the surface of the substrate material and form a uniform coating.

Too much or too little pressure may affect the adhesion effect of the ink.

2. Drying conditions:

Ensure that the ink can be fully dried after printing. Proper drying temperature and time help the ink to cure and adhere.

Insufficient drying may cause the ink layer to be too soft or not fully cured, affecting adhesion.

Fifth, other precautions

1. Avoid overprint problems:

When overprinting, ensure that the underlying ink has been fully dry to avoid being covered by the new ink layer to form a false dry phenomenon.

2. Storage conditions:

Pay attention to the storage conditions of ink and substrate materials to avoid moisture, contamination or expired failure affecting the adhesion performance of ink.

In summary, to improve the ink adhesion of wax-based carbon tape, it is necessary to choose the appropriate ink, optimize the ink formula, improve the surface properties of the substrate material, optimize the printing process conditions and other aspects. By comprehensive application of these methods, the adhesion properties of ink can be significantly improved.
