The working principle of permanent markers is mainly based on their special ink and nib design. The following is a detailed explanation of the working principle of permanent markers
1. Ink composition and characteristics
Oil-based ink: Permanent markers usually use oil-based ink, which has high adhesion and durability.
Oil-based ink is not easily dissolved by water or other solvents, so it has characteristics such as waterproof and scrub-resistant.
Pigment dispersion system: The pigment particles in the ink are finely dispersed in the solvent to form a stable dispersion system.
This dispersion system allows the ink to flow out evenly and smoothly when writing, and form clear handwriting on paper or other surfaces.
2. Nib design and writing process
Special nibs: The nibs of permanent markers are usually specially designed to ensure uniform ink flow and clarity of handwriting.
Some nibs may contain tiny balls or gaps, which help the ink flow smoothly.
Writing process: When the nib comes into contact with paper or other surfaces, the ink flows out through the nib and adheres to the surface.
Due to the high adhesion and durability of the ink, the handwriting can remain clear for a long time and is not easy to fade.
3. Persistence and waterproofness of handwriting
Persistence:
The handwriting of permanent markers usually has a long durability and can remain clear in a variety of environments.
This is due to the stability of oily inks and the fine dispersion of pigment particles.
Waterproofness:
Since oily inks are not easily dissolved by water, the handwriting of permanent markers usually has good waterproofness.
This makes the handwriting less likely to blur or fade when encountering water or other liquids.
The working principle of permanent markers is mainly based on their special oily inks and pen tip design. These characteristics enable permanent markers to form long-lasting, clear, and non-fading handwriting on a variety of surfaces, and have good waterproof properties.
