What is the structure of the wax-based carbon belt?

The structure of the wax-based carbon strip is usually complex, designed to meet various printing needs and ensure the clarity and durability of the print effect. In general, the wax-based carbon belt is mainly composed of the following key components:

First, the core structure layer

1. Tape Base:

The base of the wax-based carbon strip is a thin, strong band base, usually made of polyester or other high-density materials, that provides the necessary support and strength for the carbon strip.

2. Ink layer:

Attached to the tape base is the wax and resin as the main components of the ink layer. Wax occupies a large proportion, giving the carbon belt good lubricity and transferability. The resin helps to enhance the adhesion and durability of the ink layer.

Second, functional coating

In order to improve the performance and use experience of wax-based carbon strips, a variety of functional coatings are usually added to their surface and interior:

1. Top coating/Heat resistant protective coating:

Located above the ink layer, the main purpose is to improve the heat resistance of the carbon strip and prevent damage to the ink layer when printing in a high temperature environment. This layer of material is usually stripped before the carbon strip is used and is wrapped around the cylinder during installation.

2. Inner coating:

Located between the ink layer and the tape base, it helps to enhance the bonding force between the ink layer and the tape base, ensuring the clarity and durability of the printed content.

3. Antistatic coating:

Usually located on the back of the carbon strip, it is used to reduce the electrostatic effect of the carbon strip, protect the print head from electrostatic wear, and reduce the failure rate during the printing process.

4. Back coating:

The back coating not only helps prevent static, but also equalizes heat and reduces friction, further protecting the print head and extending its service life.

Third, additional structure

In addition to the above core structural layers and functional coatings, wax-based carbon bands may also contain the following additional structures:

1. Strong adhesive layer:

In some wax-based carbon strips, a strong adhesive layer is added between the back coating and the strip base to enhance the overall toughness and durability of the carbon strip.

2. Marking board and stop tag:

The two ends of the wax based carbon tape are usually bonded to the marking board to facilitate the installation and use of the carbon tape. At the same time, the carbon belt will also be affixed with a stop mark, so that when the carbon belt is exhausted, it will remind the operator to replace the new carbon belt in time.

3. Shaft cylinder:

The inner surface of the carbon belt body is wound on the outer surface of the shaft cylinder, and the design of the shaft cylinder helps to wind and install the carbon belt. The side wall of the inner cavity of the shaft cylinder may also be provided with non-slip teeth or non-slip textures to prevent the carbon strip from sliding during winding.

To sum up, the structure of the wax-based carbon belt is a complex system integrating a variety of materials and functional coatings. Each part plays an integral role in ensuring the excellent performance and stable performance of the wax-based carbon strip in a variety of printing scenarios.
