Advantages of Defoamers for Sprinkling Ink
In the production and application of inks, the foam problem has always been a headache.
These bubbles not only affect the fluidity of the ink, but may also have an adverse effect on the
printing quality. Sprinkling ink, as a common type of ink, also faces the same challenge. Therefore,
as an effective solution, defoamers for pouring inks have received widespread attention
and application.
1. Definition of Defoamers for Sprinkling Ink
Defoamers for pouring inks are chemical additives specifically used to eliminate foam in pouring inks.
It can effectively inhibit and destroy the foam generated during the production, storage
and use of inks, thereby ensuring the stability of the ink and the printing quality.
2. Main ingredients of defoamers for pouring inks
Defoamers for pouring inks are mainly composed of active ingredients, emulsifiers, carriers and
emulsifying aids. Among them, the active ingredient is the core part, which is mainly
responsible for breaking bubbles and reducing surface tension; the emulsifier disperses the active
ingredient into small particles to promote its better dispersion in the ink, thereby improving
the defoaming effect; the carrier occupies a large proportion of the defoamer, mainly plays a supporting
role, helps to suppress and defoam, and can also reduce production costs; the
emulsifying agent further optimizes the emulsification effect.
3. Advantages of spray ink defoamers
Fast defoaming and long-lasting defoaming: spray ink defoamers can quickly diffuse to the
surface of the foam, reduce its surface tension, thereby destroying the stability of the bubble film,
and causing the bubbles to quickly break and disappear. At the same time, it also has a long
defoaming time, which can effectively prevent the re-generation of foam.
Improve printing quality:
Foam will affect the uniformity and fluidity of the ink, resulting in a decrease in printing quality.
Spray ink defoamers can eliminate foam, make the ink more uniform
and smooth, thereby improving printing quality and making printed products clearer and more beautiful.
Enhance ink stability:
The presence of foam will make the ink unstable and prone to fluctuations and stratification.
The defoamer for pouring ink can eliminate foam, improve the stability of
ink, and make it less likely to change during use, thereby ensuring the consistency and stability of printing.
Environmental protection and safety: Modern pouring ink defoamers are mostly environmentally
friendly prodts, non-toxic and harmless, and meet environmental protection requirements.
It will not pollute the environment or harm human health during use.
Wide range of applications:
pouring ink defoamers are suitable for various pouring inks, including water-based inks, oil-based inks, etc.
Whether it is traditional printing or modern digital
printing, pouring ink defoamers can be used to eliminate foam problems.
4. How to use pouring ink defoamers
When using pouring ink defoamers, it is recommended to follow the principle of using small amounts and
multiple times, and add low-concentration dilute emulsions in a continuous or
semi-continuous manner. This ensures that the defoamer can be evenly dispersed in the ink and give full play
to its defoaming effect. At the same time, it can also avoid the problem of
excessive addition leading to reduced ink performance.
5. Summary
Due to its advantages of rapid defoaming, improved printing quality, enhanced ink stability, environmental safety
and wide application range, the defoaming agent for curtain coating ink
plays an important role in the production and application of ink. Selecting and using the appropriate defoaming
agent for curtain coating ink is of great significance in improving printing
quality, reducing production costs and protecting the environment.
