All carbon, painting tools, black, all carbon, similar to carbon rods. The composition elements are basically the same as those of charcoal pen, except that the refill is thicker and the outer surface is wrapped with a film. Often used in sketches, sketches and other paintings.

Carbon ink is an amorphous carbon. Light, loose and extremely fine black powder, with a huge surface area of 10 to 3000m2/g, is the product of incomplete combustion or thermal decomposition of carbonaceous materials (coal, natural gas, heavy oil, fuel oil, etc.). ) in the case of insufficient air.

The difference between carbon ink and non-carbon ink;

The main component of carbon ink is carbon, which has stable chemical properties at normal temperature and pressure and is not easy to react with other substances. Therefore, words written in carbon ink are easy to preserve and not easy to fade.

The main difference is that carbon is waterproof, and the color is black and bright, but it is easy to block the pen. Pigment ink is colloid, and dye ink is solution (so dye ink is relatively more stable, and there is little precipitation unless it deteriorates).

Non-carbon ink will not block the pen, but the color will not be as dark as carbon ink. For example, black may not be deep enough, and it is easy to print paper with good fluidity (which I can't accept most).

Carbon ink is black enough to prevent the pen from sticking, but it won't stick for a long time. Nano-carbon ink is extremely black in writing music, especially carbon ink, but the particles are nano-scale, so it is not easy to block the pen. There is also catfish carbon ink, which uses the same ions to repel each other, so it will not be so easy to block the pen. Basically, there are too many pens, and carbon ink will not be blocked.

Usually we see red, blue, black and blue-black, especially black ink, which is the most widely used. Bian Xiao will tell you more. When using ink, you need to use the same color, and different inks will cause chemical reactions when mixed together.

Generally speaking, it is the phenomenon of aggregation in ink, which is not conducive to our writing. If the pen cap is not covered in time after writing, the ink in the pen tip will react with air and dry, which will bring inconvenience to the next use. So everyone should pay attention to these when using ink.
