Water-based ink defoamer: Characteristics, uses and safety
Date: Dec 12 2023 From: Star Color
Water-based ink is a kind of ink made of water as a solvent or dispersant, which is widely used in the printing industry because of its environmental friendliness and excellent printing performance.However, during the preparation and use of water-based ink, the formation of foam is a common problem, which will affect the printing quality, coating quality and production efficiency.In order to solve this problem, the use of water-based ink defoamer has become an effective means.
Characteristics of water-based ink defoamer
Water-based ink defoamer is a chemical specifically designed to remove foam from water-based inks.It has the following features:
Mechanism of defoaming action
Water-based ink defoamer plays a defoamer role in two ways:Breaking and inhibiting bubbles.Defoaming means that the defoaming agent can quickly penetrate into the interior of the foam, reducing the stability of the foam, and thus causing it to burst.Foam suppression means that the antifoam agent can inhibit the production of foam by forming a film on the surface, preventing gas from entering the foam, so that the foam can not form.
Chemical properties of water-based ink defoamer
The chemical composition of water-based ink defoamer is diverse, mainly including polyoxyethylene non-ionic surfactants, silicone, polyester, polyether，etc.These ingredients can produce different defoaming effects according to different proportions and combinations.These ingredients can produce different defoaming effects according to different proportions and combinations.
Performance evaluation of water-based ink defoamer
Evaluating the performance of water-based ink defoamer mainly includes the following aspects:Defoaming speed, foam stability, use concentration and durability.Defoaming speed refers to the ability of defoaming agent to eliminate foam rapidly in a short period of time;Foam stability refers to the ability of foam not to re-form within a certain period of time；Use concentration refers to the minimum concentration required to achieve the best defoaming effect;Persistence refers to the ability of the defoamer to continue to act as a defoamer over a long period of time.
Use of water-based ink defoamer
Water-based ink defoamer has a wide range of applications in the following aspects:
printing process
In the printing process, the production of foam will seriously affect the printing quality and production efficiency.Water-based ink defoamer can effectively eliminate foam and improve printing quality and production efficiency.In addition, by using water-based ink defoamer, the impact of foam on the printing plate and the press can be reduced, and the service life of the equipment can be extended.
Preparation and use of water-based ink
In the process of preparing and using water-based ink, the generation of foam often affects its quality and performance.Water-based ink defoamer can effectively eliminate these foams and improve the quality and performance of water-based ink.At the same time, the use of water-based ink defoamer can also avoid problems such as coating defects and bubbles, and improve the stability and durability of the coating.
Safety of water-based ink defoamer
For the safety of water-based ink defoamer, we need to evaluate from the following aspects:
toxicological evaluation
Toxicity assessment is an important index to evaluate the safety of a substance to human body and the environment.For water-based ink defoamer, its toxicity depends on the nature and concentration of its composition.In general, the composition of most water-based ink defoamer has less impact on the human body and the environment at low concentrations.However, long-term exposure to high concentrations of water-based ink defoamer may have a certain impact on human health.Therefore, the relevant safe operating procedures and product instructions should be followed during use.
Safe use recommendations
When using water-based ink defoamer, the following recommendations can help ensure its safety and effectiveness:First of all, you should choose certified and qualified products and buy them from formal channels.Secondly, you should read the product instructions in detail before use, and use it in accordance with the recommended method and concentration.In addition, attention should be paid to wearing protective clothing, gloves, masks and other personal protective equipment to avoid long-term or large amounts of contact with the skin or inhalation of its gas.Finally, the used water-based ink defoamer waste liquid should be treated in accordance with relevant laws and regulations and environmental requirements to avoid impact on the environment and human health.
Water-based ink defoamer plays an important role in the printing industry and in the preparation and use of water-based ink.It has the characteristics of fast defoaming, high stability and environmental friendliness, which can improve printing quality and production efficiency, and improve coating performance and stability.However, attention should be paid to its safety and toxicity issues during use. Purchase qualified products from regular channels according to the instructions for product use. When handling waste liquid, personal protective equipment should comply with relevant laws and regulations and environmental requirements to minimize the impact on the environment and human health.With the continuous development of science and technology and the continuous improvement of environmental awareness, it is believed that the future water-based ink defoamer will be applied in a wider range of fields and play an important role. At the same time, we also need to strengthen the research and monitoring of its safety and environmental impact to maximize its advantages and ensure that its safety is safe for the environment and human health.
Through the above analysis, the following conclusions can be drawn:
Water-based ink defoamer plays an important role in the printing and preparation of water-based ink, which can effectively eliminate foam, improve printing quality and production efficiency, and also help to improve the stability and durability of the coating.
When evaluating the safety of water-based ink defoamer, it is necessary to consider its toxicity and effects on the environment and human health.Most of the components of water-based ink defoamer have little impact on the human body and the environment at low concentrations, but when exposed to high concentrations of defoamer for a long time, it may have a certain impact on human health.
When using water-based ink defoamer, you should follow the relevant safe operating procedures and product instructions, select certified and qualified products, and purchase them from regular channels.At the same time, attention should be paid to the correct use of personal protective equipment, such as protective clothing, gloves, masks, etc., to avoid long-term or large amounts of contact with the skin or inhalation of its gas.
The used waste liquid of water-based ink defoamer should be treated in accordance with relevant laws and regulations and environmental requirements to avoid impact on the environment and human health.
In summary, water-based ink defoamer plays an important role in the printing and preparation of water-based ink, but attention should be paid to its safety and toxicity.The correct use of water-based ink defoamer, while strengthening the research and monitoring of its safety and environmental impact, can maximize its advantages, ensure printing quality and production efficiency, while protecting human health and environmental safety.
