What are the key steps in the production process of enhanced wax based carbon ribbon?

The production process of enhanced wax based carbon ribbon mainly includes the following key steps:

1、 Raw material preparation

Substrate selection:

The base film is a carrier for enhancing wax based carbon ribbon, usually made of polyester (PET) film due to its excellent mechanical strength and thermal stability.

The thickness and performance of the base film need to be selected according to the requirements of the final product.

Ink raw material preparation:

Ink is mainly composed of wax substances, resins, pigments, and various additives (such as wear-resistant agents, solvent resistant agents, etc.).

These raw materials need to be mixed in a certain proportion to ensure that the performance of the ink meets the requirements.

2、 Ink preparation

Mixing evenly:

Mix wax and resin thoroughly and evenly while heating and melting.

Then use a basket grinder to thoroughly mix it with pigments, additives, etc. to make ink.

Quality Control:

During the preparation process, it is necessary to test the viscosity, flowability, and other properties of the ink to ensure that it meets the requirements of subsequent coating processes.

3、 Coating process

Coating operation:

Apply the prepared ink onto the surface of the base film, with a coating amount controlled within a certain range (such as 2.2-3.5 grams per square meter) to ensure the uniformity and thickness of the ink layer.

The coating process needs to be carried out in a controlled environment to avoid pollution and uneven coating.

Drying and curing:

The coated carbon ribbon needs to undergo processes such as air cooling or drying in a drying oven to remove solvents and solidify the ink layer.

The temperature and time for drying and curing need to be adjusted according to the properties of the ink and the requirements of the base film.

4、 Coating and curing of heat-resistant ink

Heat resistant ink coating:

Apply heat-resistant ink on the other side of the base tape, with a coating amount typically ranging from 0.1 to 1 gram per square meter.

The application of heat-resistant ink aims to improve the heat resistance and printing effect of carbon ribbon.

Drying and curing:

After applying heat-resistant ink, it needs to go through processes such as drying in a drying oven to solidify the ink layer and improve its adhesion and wear resistance.

5、 Winding and cutting

Winding:

Roll the coated and cured carbon tape onto a drum for subsequent use and storage.

Cutting:

Cut the carbon ribbon into different width specifications according to the needs of different models of printers.

6、 Quality Inspection and Packaging

quality testing:

Conduct quality inspection on the produced reinforced wax based carbon ribbon, including testing of adhesion, wear resistance, clarity, and other indicators.

Ensure product quality meets relevant standards and customer requirements.

packing:

Pack the qualified carbon ribbon for transportation and storage.

The packaging material should have moisture-proof, dust-proof and other properties to protect the carbon ribbon from damage.

In summary, the production process of enhanced wax based carbon ribbon includes key steps such as raw material preparation, ink preparation, coating process, heat-resistant ink coating and curing, winding and cutting, as well as quality inspection and packaging. Each stage requires strict control over quality and technical parameters to ensure that the performance and quality of the final product meet the requirements.
