Judging the quality of the enhanced mixed base carbon belt can be considered from the following aspects:
First, appearance inspection
1.Surface smoothness: The surface of the high-quality reinforced mixed base carbon strip should be smooth and smooth, without folds, bubbles or impurities. Wrinkles and bubbles may affect the print, resulting in indistinct writing or white space.
2.Coating uniformity: Check whether the coating of the carbon strip is uniform and whether the ink distribution is consistent. Uneven coating of carbon tape may appear different shades of writing when printing.
3.Paper core diameter: The inner diameter of the carbon strip paper core should meet the standard specifications (generally 25.4mm), too large or too small may affect the installation and use of the carbon strip on the printer.
Second, print effect test
1.Imprint clarity: The imprint clarity of the carbon strip is tested by actual printing, including blackness, evenness, and edge clarity. High quality carbon tape should be able to print clear, full, uniform ink.
2.Wear resistance: Evaluate the wear resistance of the carbon strip, that is, whether the printed content is prone to fading or wear after prolonged use or friction. The carbon belt with good wear resistance has a longer service life and a longer printing effect.
3.Scratch resistance: For application scenarios that require scratch resistance, special attention should be paid to the scratch resistance of the carbon strip. It can be tested by a specialized scratch tester, and high quality reinforced mixed base carbon strips usually have good scratch resistance.
Third, physical performance test
1.Tensile strength: A tensile test machine is used to measure the strength of the carbon strip under tensile forces to assess its durability. The carbon belt with high tensile strength is not easy to break during use, and is more suitable for high-speed printing and continuous printing.
2.Thermal stability: Test the stability of the carbon strip by exposing it to a high temperature environment to see if there is bending, shrinkage or deformation. Good thermal stability can reduce the carbon strip in the printing process due to high temperature problems.
Fourth, other performance indicators
1.Electrostatic protection: High-quality carbon strips are often added with electrostatic protection agents to reduce the probability of electrostatic generation, which helps protect the printer and printing media from electrostatic interference.
2.Compatibility: Consider the compatibility of the carbon belt and the printer used to ensure that the carbon belt can be smoothly installed and used on the printer to avoid paper jam, carding and other failures.
Fifth, refer to user reviews and professional advice
1.User reviews: Review reviews and feedback from other users to understand how the carbon strip performs in actual use.
2.Professional advice: Consult professionals or suppliers for more professional purchase advice.
To sum up, judging the quality of the enhanced mixed base carbon strip requires comprehensive consideration of appearance, printing effect, physical properties and other performance indicators. At the same time, referring to user evaluation and professional advice is also an important way to buy high-quality carbon belts.
