What are the quality control points in the production of wax-based carbon strips?

There are many quality control points in the process of producing wax-based carbon strip, which are directly related to the performance and quality of the final product. Here are some key quality control points:

First, raw material quality control

1.Base film selection: high-quality PET film is selected as the base film to ensure that the base film has excellent mechanical strength and thermal stability, which is the basis for the production of high-quality wax-based carbon strips.

2.Ink formula: accurately control the proportion of wax substances, resins, colorants and additives in the ink to ensure stable ink performance and meet printing requirements.

Second, coating process control

1.Coating uniformity: In the coating process, it is necessary to ensure that the ink layer is uniform, no white spots, no stripes and other defects, which directly affects the printing effect and the durability of the carbon strip.

2.Coating amount control: precise control of coating amount to avoid problems caused by too much or too little. Too much coating will increase the cost and may affect the print quality; Too little coating may not be able to meet printing needs.

Third, drying and curing control

1.Drying temperature and time: According to the ink characteristics and equipment conditions, set the appropriate drying temperature and time to ensure that the ink layer is quickly dried and cured to improve the printing performance and durability of the carbon strip.

2.Check the curing effect: check the carbon belt after curing regularly to ensure that the curing effect is good, and there is no uncuring or incomplete curing phenomenon.

Four, slitting and rewinding control

1.Slitting accuracy: The use of advanced slitting equipment to ensure the accuracy and accuracy of carbon strip slitting, avoiding the problem of excessive width deviation or irregular edges.

2.Rewinding tension control: During the rewinding process, the tension and tightness of the carbon strip need to be precisely controlled to avoid wrinkles or breaks when the carbon strip is printed on the printer.

Fifth, environmental control

1.Temperature and humidity control: The production workshop needs to be equipped with a dust-free floor and maintain appropriate temperature and humidity conditions to reduce the impact of dust on the carbon belt and ensure a clean and stable production environment.

2.Esd prevention: Take effective measures to prevent damage to carbon belts caused by static electricity, such as using anti-static materials and increasing air humidity.

Sixth,quality inspection and control

1.Online testing: Online testing equipment is set up in the production process to monitor and test the performance indicators of the carbon belt in real time to ensure that product quality meets the standard requirements.

2.Finished product inspection: strict quality inspection of the finished carbon strip, including appearance inspection, size measurement, performance testing and other links to ensure the quality of the outgoing products.

Seventh,tracing and recording

1.Establish a traceability system: Establish a sound production traceability system, record and manage the raw materials, production process, testing records and other information of each batch of products in detail, so as to quickly trace the causes and take effective measures when problems occur.

2.Data statistics and analysis: Regular statistics and analysis of various data in the production process to identify potential problems and room for improvement, to provide a basis for continuous improvement of product quality.

In summary, the key points of quality control in the production of wax-based carbon strip include raw material selection, coating process, drying and curing, slitting and rewinding, environmental control, quality testing and traceability records. By strictly controlling these points, it is possible to ensure the production of high-quality, high-performance wax-based carbon strip products.
