What are the steps of the production process of wax-based carbon strips?

The production process of wax-based carbon strip mainly includes the following key steps:

First, raw material preparation

1.Base film selection: PET (polyethylene terephthalate) film is usually selected as the base band because of its good mechanical properties and chemical stability.

2.Ink formula: According to product requirements, prepare suitable wax based ink. Wax based inks are mainly composed of wax substances, resins, colorants and additives, and the proportion of each component needs to be precisely controlled to achieve the best printing effect.

Second, ink production and coating

1.Ink production: the wax substances and resins are fully mixed and uniform under the condition of heating and melting, and then the basket mill or similar equipment is used to mix it with colorants, additives, etc., to make uniform ink.

2.Coating process: The prepared ink is evenly coated on one side of the PET base film, and the coating amount needs to be precisely controlled to ensure the printing quality. During the coating process, it is necessary to ensure that the ink layer is uniform, no white spots, no stripes and other defects.

Third, heat-resistant coating (if necessary)

For some wax-based carbon strips that require higher heat resistance, a heat-resistant ink layer must also be coated on the other side of the base film. The heat-resistant ink layer is usually composed of silicone resin, nanomaterials, etc., which has excellent heat-resistant properties.

Fourth, drying and curing

After coating, the carbon strip should be dried and cured. The carbon strip is heated by the drying channel or similar equipment, so that the ink layer is quickly dried and cured to improve the printing performance and durability of the carbon strip.

Fifth, cutting and rewinding

1.Slitting: The carbon strip after drying and curing is slitted according to a specific width to meet the needs of different printers.

2.Rewinding: the carbon strip after cutting is wound on the shaft barrel to form a finished roll. In the rewinding process, the tension and tightness of the carbon strip need to be precisely controlled to ensure product quality.

Sixth,quality inspection and packaging

1.Quality testing: Strict quality testing of finished carbon strip, including wear resistance, printing effect, high temperature resistance and other performance tests to ensure that the product meets the standard requirements.

2.Packaging: The tested carbon strips are packaged to prevent damage during transportation and storage. The packaging should be clearly marked with product model, specification, production date and other information for traceability.

Seventh, warehousing and delivery

The packaged wax-based carbon tape will be stored in the warehouse and shipped according to the order requirements. Precautions such as moisture and sun protection should be taken during storage and transportation to ensure that product quality is not affected.

In summary, the production process of wax-based carbon tape includes raw material preparation, ink production and coating, heat-resistant coating, drying and curing, cutting and rewinding, quality testing and packaging, storage and delivery. Each link needs to be strictly controlled to ensure that the quality of the final product meets the requirements of the standard.
