Scope of use of roll coating ink defoamer
In the printing industry, roll coating ink is a common printing material, but in its use process, the production of foam often affects the printing quality and production efficiency. In order to solve this problem, roll coating ink defoamers have emerged. This article will provide a detailed introduction to the scope of use and importance of defoamers for rolling ink.
1、 Definition of defoamer for rolling ink
Roll coating ink defoamer is an additive specially used to eliminate foam in roll coating ink. It can quickly penetrate into the ink, reduce the surface tension, and destroy the stability of foam, so as to eliminate foam. Defoamers are usually low toxic, volatile, nonflammable and other characteristics. While preventing foam, they have little impact on ink performance and printing quality.
2、 The main types of defoamers for rolling ink
According to their composition and performance, roll coating ink defoamers can be classified into various types, including the following:
Organic silicon defoamer: has excellent defoaming and anti foaming properties, suitable for various types of inks, including water-based inks and solvent based inks. Its advantages are high efficiency, durability, and environmental friendliness.
Mineral oil defoamer: Low price, suitable for alkaline ink systems. Although cost-effective, it may affect the transparency and glossiness of the ink.
Polyether defoamer: environmentally friendly and non-toxic, especially suitable for water-based ink systems. It has good anti foaming ability and is resistant to high temperatures, strong acids and alkalis, but its use conditions are limited by temperature, and its anti foaming ability is relatively weak.
Composite defoamer: Combining the advantages of multiple defoamers, it has a wider applicability and stronger defoaming ability. It is suitable for complex production environments and has significant defoaming effects.
3、 Scope of use of roll coating ink defoamer
Roll coating ink defoamers have a wide range of applications in the printing industry, mainly including the following aspects:
Ink production stage: in the production process of ink, mixing, grinding and other operations are easy to produce a lot of foam. Defoamers can help eliminate these foam and ensure the quality and stability of the ink.
Roll coating printing process: in the roll coating printing process, foam is easily generated when the ink is transferred between the cylinder and the paper. Defoamers can effectively eliminate these foam and improve the clarity and fullness of printed matter.
Automatic production line: For printing enterprises 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、 The importance of defoamers for rolling ink
Roll coating ink defoamers play a crucial role in the printing industry. It can not only improve printing quality and reduce scrap rates, but also reduce production costs and improve production efficiency. In addition, defoamers are usually made of environmentally friendly materials that are non-toxic and harmless, in line with the green development trend of the modern printing industry.
5、 Precautions for selecting and using roll on ink defoamers
When selecting and using roll on ink defoamers, the following points should be noted:
Choose the appropriate product based on actual needs: Different types of inks and printing processes have different requirements for defoamers, so it is necessary to choose the appropriate product according to actual needs.
Pay attention to the amount of defoamer added: too much defoamer may affect the performance and printing quality of the ink, so it needs to be added in a certain proportion.
Stir evenly: After adding defoamer, it is necessary to stir thoroughly to ensure that it can fully exert its effect.
Pay attention to storage conditions: Defoamers should be stored in a dry, cool, ventilated place, away from direct sunlight and high temperatures.
In summary, roll coating ink defoamers have a wide range of applications and important roles in the printing industry. Proper selection and use of defoamers can not only improve printing quality and production efficiency, but also reduce production costs and environmental pollution. Therefore, printing companies should pay attention to the selection and use of defoamers to ensure the smooth progress of the printing process and the high-quality output of printed products.
