Problems solved by technology

The formula of the ink contains some chemical substances that are harmful to the human body, and the ink stains of most pigments are not easy to clean after being stained on clothes
Carbon ink is the most widely used black ink in fountain pens. The main colorant is carbon black. Carbon black is the product of incomplete combustion or cracking of organic matter. The main component is carbon, which is a kind of non-hydrophilic black powder. It is very finely ground, and it cannot be made into ink after adding water. It must be treated or added with special functional additives before it can be made into ink. The process is complicated, the cost is high, and the "three wastes" are serious. It is relatively high, it is insoluble in water and has no self-dispersion. It is easy to cause stratification and precipitation when it is placed for a long time, and it is also easy to cause clogging of the nib. To solve such problems, dispersants, stabilizers, suspending agents, emulsifiers, etc. are usually added. Long-term stable dispersion and suspension of carbon black in water increases the complexity and cost of the process
Carbon ink generally has uneven writing, and if it is written intermittently, it is easy to dry up and block the pen, and it cannot meet the needs of computer graphics.
In addition, today's black ink is not easy to clean after inadvertently leaving color on clothes
