Roll coating ink defoamer: a powerful assistant for optimizing printing effects
In the printing industry, the quality of ink is directly related to the aesthetics and quality of printed materials. However, in the production and application of ink, the production of foam often becomes the key factor affecting the printing effect. In order to solve this problem, roll coating ink defoamers have emerged. This article will explain to you the role and importance of defoamers in roller coating ink.
1、 The Influence of foam on Ink
During the production, storage and use of ink, it is easy to produce a lot of foam due to the mixing, stirring, grinding and other operations of raw materials. These foam will not only affect the fluidity of the ink, resulting in defects on the surface of the printed matter, but also reduce the clarity and fullness of the printed matter. In addition, foam may also affect the drying speed of ink, or even lead to printing machine failure, seriously affecting production efficiency.
2、 The function of rolling ink defoamer
Roll coating ink defoamer is an additive specially used to eliminate foam in ink. Its main functions include:
Reduce the surface tension: Defoamer can quickly penetrate into the ink, reduce the surface tension of the ink, and make foam easier to break.
Destroy the stability of foam: Defoamer can eliminate foam by destroying the membrane structure of foam, making it unable to maintain the foam state.
Control of new foam generation: In addition to eliminating the generated foam, defoamer also has the ability to control the generation of new foam, so as to maintain the stability of ink during production, storage and use.
3、 Application scenarios of roll coating ink defoamer
Roll on ink defoamers are widely used in various printing processes, especially in situations that require high-precision printing. Whether in the production stage of ink or in the printing process, defoamers can play an important role. In addition, for printing companies that use automated production lines, defoamers can be automatically added through an automatic dosing system based on actual production conditions to ensure the best defoaming effect, reduce manual intervention, and improve production efficiency.
4、 Selection and use of defoamers for rolling ink
When selecting defoamers for roll coating ink, factors such as the type of ink, printing process requirements, and defoamer performance should be considered. Ensure that the selected defoamer has good compatibility with the ink system and does not cause surface defects such as coating shrinkage, orange peel, and hair loss. During use, simply add the defoamer to the ink in a certain proportion and stir evenly. Generally speaking, the amount of defoamer added is 0.1% to 0.3% of the total ink system to achieve good defoaming effect.
5、 Environmental Protection and Safety
With the increasing awareness of environmental protection, the environmental friendliness of roll on ink defoamers is also receiving increasing attention. Modern defoamers are usually made of environmentally friendly materials, which are non-toxic and harmless to the environment. This not only meets the sustainable development requirements of the modern printing industry, but also ensures the health and safety of production workers.
6、 Conclusion
Roll coating ink defoamer, as an important additive in the printing industry, plays an important role in improving printing quality, reducing production costs, and enhancing production efficiency. With the continuous advancement of printing technology and the increasing demand for environmental protection, the performance of defoamers will also be constantly innovated and improved. In the future, roll coating ink defoamers will play a more important role in the printing industry, contributing more to the development of the printing industry.
