The manufacturing method
of ink
ink is an important material used to transmit graphic information in the printing process, which plays a key role in the quality and effect of printed matter. In the field of raw materials for chemical production, the manufacturing method of ink involves multiple links and processes. The manufacturing process of ink will be described in detail below.

1. raw materials to prepare

1. Colors: used to give ink color, common colored pigments, dyes, etc.
2. connecting material: used to connect the pigment and substrate, common natural resin, synthetic resin and so on.
3. additives: used to improve the performance of ink, such as fluidity, drying, etc., common ink, desiccant, etc.

2. ingredients

according to the predetermined formula ratio, the color material, the connecting material and the additive are mixed. This process requires attention to the order in which the raw materials are added and the stirring speed to ensure that the ingredients of the ink can be mixed sufficiently and evenly.

3. grinding

grinding is an important step to improve the fineness and dispersion of ink. The pigment particles in the ink are ground to nano-scale through equipment such as a high-speed grinder or sand mill, so that they can be better dispersed in the binder. During the grinding process, it is necessary to control the grinding time and temperature to avoid excessive refinement or agglomeration of pigment particles.

4. detection and adjustment
After the
grinding is completed, the performance of the ink needs to be detected and adjusted. Common test items include color, fineness, viscosity, etc. According to the test results, you can adjust the proportion of ingredients or add the right amount of additives to achieve the desired ink performance.

5. filtration and packaging

Finally, the manufactured ink is filtered to remove impurities and particles, and then packaged for transportation and use.

The above are the basic steps of ink manufacturing, and the specific process and operation will vary according to different types of inks and equipment. In the manufacturing process, it is necessary to strictly abide by the safety operation procedures to ensure the smooth progress of the production process and the stability of product quality.

In short, the manufacturing method of ink involves multiple links and processes, and the operation and quality of each step need to be strictly controlled to ensure the performance and quality of the final product. At the same time, with the continuous development of science and technology, ink manufacturing technology and process are constantly improving and optimizing, providing more possibilities for improving the quality and effect of printed matter.
