1. Initial write performance.
The initial writing performance of a ballpoint pen refers to the writing performance of the pen when it is first used. A good ballpoint pen should have a smooth, smooth initial writing performance, so that the user can start writing easily.
2. Writing performance.
The writing performance of a ballpoint pen refers to the performance of the pen when writing continuously. A good ballpoint pen should have a stable and smooth writing performance, so that the user can write continuously and quickly.
3. Permeability.
The permeability of a ballpoint pen refers to the ability of the pen and ink to penetrate on the paper. A good ballpoint pen should have moderate permeability, allowing the ink to penetrate evenly across the paper while avoiding the ink from forming water droplets or smudging on the surface of the paper.
Fourth, dryness.
The dryness of a ballpoint pen refers to the speed and degree of drying of the pen and ink on the paper. A good ballpoint pen should have a fast drying speed and a good degree of drying, so that the ink can dry in a short time and avoid the ink smudging or blurring.
5. Reproducibility.
The copyability of a ballpoint pen refers to the performance of the pen and ink when copying. A good ballpoint pen should have good copyability, so that the user can easily copy clear text or images.
6. Water resistance.
The water resistance of a ballpoint pen refers to the stability and water resistance of the pen and ink in water. A good ballpoint pen should have good water resistance, so that the ink is not easy to smudge or blur in water.
7. Lightfastness.
The lightfastness of a ballpoint pen refers to the stability and light resistance of the pen and ink under light conditions. A good ballpoint pen should have good lightfastness, so that the ink is not easy to fade or fade under light conditions.
8. Intermittent writing.
Intermittent writing of a ballpoint pen refers to the writing performance of the pen after a long period of unused use. A good ballpoint pen should have good intermittent writing performance, so that the user does not need to make additional adjustments or lubrication before use.
9. Writing lubrication.
The writing lubrication of a ballpoint pen refers to how smooth the pen is when writing. A good ballpoint pen should have good writing lubrication, so that the user can easily write smooth and smooth text.
10. Preservation.
The preservation of a ballpoint pen refers to the preservation effect of the pen after use. A good ballpoint pen should have good preservation, so that the user can keep the used ink and refills for a longer period of time.
Ten. 1. Friction resistance.
The scratch resistance of a ballpoint pen refers to the stability and rub resistance of the pen and ink when wiping. A good ballpoint pen should have good scratch resistance, allowing the user to easily wipe off ink marks without affecting the clarity of text or images.
Ten. 2. Ethanol resistance.
The ethanol resistance of a ballpoint pen refers to the stability and resistance of the pen and ink in ethanol. A good ballpoint pen should have good ethanol resistance, so that the user can use it in an ethanol environment without affecting the stability and writing performance of the ink.
Ten. 3. Hydrochloric acid resistance.
The resistance of ballpoint pen to hydrochloric acid refers to the stability of the pen and ink in hydrochloric acid and the ability to resist hydrochloric acid. A good ballpoint pen should have good resistance to hydrochloric acid, so that the user can use it in a hydrochloric acid environment without affecting the stability and writing performance of the ink.
Ten. Fourth, ammonia resistance.
The ammonia resistance of a ballpoint pen refers to the stability and resistance of the pen and ink in ammonia. A good ballpoint pen should have good resistance to ammonia, so that the user can use it in an ammonia environment without affecting the stability and writing performance of the ink.
