Ink coating defoamer
In the production and application of ink and coatings, the foam problem is often a headache. These foams not only affect the quality of the product, but also lead to decreased production efficiency and even damage to the equipment. In order to solve these problems, defoamer has become an essential additive. In this paper, the function, type and application of ink coating defoamer are introduced in detail.
First, why do you need to use defoamer?
01, the cause of the bubble:
In the production and application process of ink and coating, due to mechanical mixing, chemical reaction or air mixing, it is easy to produce a large number of foams. Especially in high-speed mixing, pumping or spraying operations, the foam problem is particularly prominent.
02. Problems caused by bubbles:
Affect product quality: foam can lead to uneven ink or paint surface, affecting the gloss and uniformity of the coating.
Reduced production efficiency: Foam can occupy container space and reduce effective volume, resulting in reduced production efficiency.
Increased cost: Foam can lead to material loss and increased consumption of raw materials and energy.
Risk of equipment damage: Excessive foam can spill over the equipment, causing contamination or damage to the equipment, especially for automated production lines, where foam problems can lead to serious production failures.
Therefore, in the production and application of inks and coatings, the use of defoamer is a necessary measure to ensure efficient and high-quality production.

Common types of ink coating defoamer
According to different application scenarios and needs, defoamer can be divided into a variety of types, the following are some common ink coating defoamer types:
01, silicone defoamer:
Features: Excellent anti-foaming and anti-foaming properties, suitable for various types of inks and coatings.
Advantages: Efficient, durable, environmentally friendly.
Scope of application: Widely used in water-based ink, solvent-based ink, latex paint and other coating systems.
02, mineral oil defoamer
Features: low price, suitable for alkaline system inks and coatings.
Advantages: Cost-effective, suitable for mass production.
Disadvantages: May affect the transparency and gloss of some inks or coatings.
03, polyether defoamer:
Features: Environmental protection and non-toxic, suitable for water-based system of ink and paint.
Advantages: Environmentally friendly, suitable for the electronics industry and other occasions with high environmental protection requirements.
Scope of application: Mainly used in water-based ink, latex paint and other water-based coating system.
04, compound defoamer:
Features: Combined with the advantages of a variety of defoaming agents, it has a wider applicability and stronger defoaming ability.
Advantages: Suitable for complex production environment, anti-foam effect is remarkable.
Scope of application: Widely used in various ink and coating systems.
Three.
Application scenario
Defoamer has a wide range of application scenarios in the production and application of ink and coatings, mainly including the following aspects:
01, production stage:
In the production process of ink and paint, stirring, mixing, grinding and other operations are easy to produce a large number of foams. At this time, adding appropriate amount of defoamer can effectively control the generation of foam, improve production efficiency and product quality.
02. Construction phase:
In the construction process of ink and paint, such as spraying, brush coating, roll coating and other operations, the foam problem can not be ignored. The defoamer can help eliminate the foam generated during the construction process and ensure the smoothness and beauty of the coating.
03, automatic production line:
For enterprises using automated production lines, the defoamer can be automatically added according to the actual production situation through the automatic dosing system to ensure the best defoamer effect, reduce manual intervention, and improve production efficiency.
