How to make ink
Ink has a long history as a common writing and printing material, and the production process is constantly evolving. Whether it is traditional carbon ink or modern dye ink, its production process contains rich scientific principles and technical details. This article will combine recent hot topics and hot content to introduce in detail the production methods, classification and related data of ink.
1. Classification of ink
Inks can be divided into the following categories based on their uses and ingredients:
| Type | Main ingredients | Purpose |
|---|---|---|
| carbon ink | Carbon black, water, adhesive | writing, painting |
| dye ink | Synthetic dyes, water, solvents | Printers, inkjet printing |
| Pigment ink | Pigment particles, water, dispersant | art creation, printing |
| Fluorescent ink | Fluorescent dye, water | special markings, decorations |
2. Ink production process
The process of making ink varies by type, but here are typical methods for making carbon and dye inks:
1. Production of carbon ink
Carbon ink is one of the most traditional inks. The production steps are as follows:
(1) Mix carbon black powder and adhesive (such as gum arabic);
(2) Add appropriate amount of water and stir evenly;
(3) Grind the mixture through a grinder until fine and uniform;
(4) Filter to remove impurities to obtain the finished ink.
2. Production of dye ink
Dye ink is a commonly used ink in modern printers. The production steps are as follows:
(1) Dissolve synthetic dyes in water or organic solvents;
(2) Add stabilizers and preservatives to prevent the ink from deteriorating;
(3) Adjust the pH value to ensure the stability of the ink;
(4) Encapsulate after filtering.
3. Ink performance indicators
The quality of ink is usually measured by:
| indicator | Description | ideal range |
|---|---|---|
| viscosity | Ink fluidity | 1-10mPa·s |
| pH value | The acidity and alkalinity of ink | 7-9 |
| Chroma | shade of color | Adjust according to needs |
| Stability | Ink shelf life | ≥2 years |
