Do You Understand Neutral Pens? How Is Its Lubricity?

Neutral pens are one of the important stationery items for writing. Do you know why the writing effect is good or not? Below, the editor has compiled the lubrication performance and blending of neutral pens. Interested parties can learn more about it with the editor.

The outstanding difference between neutral ink and regular ink is that it not only has fluency, but also needs to have a certain degree of lubricity. The addition of lubricant reduces the friction between the ball and the seat, minimizing the loss of kinetic energy and achieving a more comfortable writing feel. Solving the lubrication problem of ink is also a comprehensive auxiliary system. Its characteristic is to have highly polar additives and solvents as guarantees,

At the same time, it is necessary to achieve a reasonable combination of surface activity and lubricant, as the two are closely related and either side will affect the effectiveness of the ink.

The key to the lubricity of neutral ink lies in the use of lubricants. In the search for lubricants, high molecular weight lubricants or greases are mainly used, supplemented by additives and surfactants, and reasonably combined to achieve better results.

Neutral ink, due to its high viscosity, mainly uses polar and significantly wetting alcohols and organic ethers as additives and solvents to effectively break the entanglement of ink interweaving. Organic solvents suitable for pigment dispersion can also be selected, and a certain amount of surfactants can be added to adjust the intermittent performance, continuous writing performance, and ink output of the ink.
