Manufacturing Method of Ink
Ink is an important material used to transmit graphic information in the printing process, and plays a key role in the quality and effect of printed materials. In the field of raw materials for chemical production, the manufacturing method of ink involves a number of links and processes, and the following will introduce the manufacturing process of ink in detail.
I. Raw material preparation
1. color pigment: used to give ink color, common colored pigments, dyes and so on.
2. Connecting material: Used to connect the color pigment and the substrate, common natural resins, synthetic resins and so on.
3. Additives: used to improve the performance of ink, such as fluidity, dryness, etc., common ink blending oil, desiccant, etc..
II. Ingredients
According to the predetermined proportion of the formula, the color, connecting material and additives are mixed. This process requires attention to the order of addition of raw materials and mixing speed to ensure that the components of the ink can be fully and evenly mixed.
Three, grinding
Grinding is an important step to improve the fineness and dispersion of ink. Through high-speed mills or sand mills and other equipment, the pigment particles in the ink are ground to the nanometer level, so that they can be better dispersed in the connecting material. Grinding time and temperature need to be controlled during the grinding process to avoid excessive refinement or agglomeration of pigment particles.
Four, testing and adjustment
After the grinding is completed, the performance of the ink needs to be tested and adjusted. Common testing items include color, fineness, viscosity and so on. According to the test results, the proportion of ingredients can be adjusted or the right amount of additives can be added to achieve the expected ink performance.
V. Filtering and Packaging
Finally, the finished manufacturing ink is filtered to remove the impurities and particles in it, and then packaged for transportation and use.
The above are the basic steps of ink manufacturing, the specific process and operation will vary according to different types of ink and equipment. In the manufacturing process, it is necessary to strictly observe the safety operation procedures to ensure the smooth running of the production process and the stability of product quality.
In short, the manufacturing method of ink involves a number of 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 processes are also constantly improving and optimizing, providing more possibilities for improving the quality and effect of printed products.
