The Advantages And Performance Indicators Of A Neutral Pen

Although neutral ink pens belong to ballpoint pen products, their writing principle, pen head structure, and processing technology are similar to traditional oil-based ballpoint pens. However, due to differences in ink performance, there are special requirements for the pen head. The development of neutral ink is difficult. Currently, neutral ink is produced in countries such as Japan, the United States, Germany, and South Korea, with Japan being the best. The key to the development of neutral ink is: ink formula; Formula processing technology; Matching ink with pen tip.

Firstly, in the development of the formula, it is necessary to ensure that the ink has appropriate viscosity, surface tension, and pH value. Not only should the pen be smooth and leak free, but also the ink's light resistance, water resistance, heat resistance, cold resistance, moisture retention, and permeability should be guaranteed. At the same time, it is necessary to solve the stability of ink, ensure long-term storage, prevent ink from deteriorating, and prevent delamination and precipitation, while also ensuring the safety of ink
Full, non-toxic, and corrosive.

Neutral pens should not only consider the advantages of oil-based ballpoint pens and water-based ballpoint pens, but also have the following quality indicators.

(1) Ink has strong universality and can be more widely matched with pen tips to achieve better writing performance, thus becoming a better supporting product for pen manufacturers.

(2) Ink is required to have corresponding false shrinkage and viscosity puncture properties, with long intermittency to achieve longer de capping time.

(3) Ink should reach a certain particle fineness, lower than the gap between the bead and the seat, and have strong dispersibility to prevent the pen head from clogging and affecting writing.

(4) Ink has strong stability and can write normally under certain room temperature conditions. The ink does not layer evenly.

(5) There is sufficient writing length, that is, one tube of ink can draw longer lines on the marking machine.
