What are the components of wax based carbon ribbon?

The composition of wax based carbon ribbon mainly includes the following parts:

1. Wax:

Wax is the main component of wax based carbon ribbon, which determines the melting point and printing performance of the ribbon.

Common types of wax include paraffin wax, beeswax, synthetic wax, etc. These waxes have different melting points and hardness, and can be selected according to printing needs.

2. Carbon black:

Carbon black is a coloring agent in carbon ribbon, which gives the ribbon a black color, making the printed barcode or text clear and distinguishable.

Carbon black also has a certain degree of conductivity, which helps to transfer heat during the printing process, causing the wax to melt and adhere to the label paper.

3. Resin (may contain, but not the main component):

In some wax based carbon ribbons, a small amount of resin may be added to improve their performance.

The addition of resin can improve the scratch resistance, solvent resistance, and high temperature resistance of carbon ribbon, but it also increases costs.

4. Auxiliary:

Additives are used to improve the processing performance, printing performance, and storage stability of carbon ribbons.

For example, anti-static agents can be added to prevent the carbon ribbon from generating static electricity during the printing process, or lubricants can be added to reduce friction between the print head and the carbon ribbon.

5. Colorants (in addition to carbon black, there may be other colors):

Although most wax based carbon ribbons are black, there are also some special applications of carbon ribbons that may use colorants of other colors.

In summary, the composition of wax based carbon ribbon mainly includes wax, carbon black, possible resins, additives, and coloring agents. These components collectively determine the printing performance, durability, and applicability of carbon ribbon. When selecting and using wax based carbon ribbons, it is necessary to consider the specific printing requirements and label materials comprehensively.
