Water-based non-silicon defoamer: the anti-foam of many industries
In industrial production and daily life, the generation of foam is often a headache. Whether it is the foam during
paint production that affects the coating effect or the quality risks caused by foam during food processing, effective
solutions are urgently needed. As a new type of defoaming product, water-based non-silicon defoamer has become a
powerful assistant in many industries to fight foam with its unique performance and wide applicability.
I.Defoaming principle of water-based non-silicon defoamer
Water-based non-silicon defoamer is mainly composed of special surfactants, dispersants, stabilizers and other ingredients.
Its defoaming process is based on three key steps: first, the defoamer is quickly dispersed into the foam system, using its own
low surface tension to quickly spread on the foam surface; then, it will destroy the surface film of the foam, causing the surface
tension of the foam to lose balance; finally, it will cause the foam to burst, thereby achieving the effect of defoaming and
suppressing foam. Unlike traditional silicon-containing defoamers, water-based non-silicon defoamers will not produce side
effects such as silicon spots and oil shrinkage due to silicon components, and have obvious advantages in some fields with
extremely high surface quality requirements.
II. Application in the coating industry
During the production and construction of coatings, the generation of foam will seriously affect the performance and use effect
of the coating. For example, foam will cause pores and pinholes on the surface of the coating, reduce the gloss and fullness of
the coating, and affect the appearance; at the same time, it may also affect the adhesion of the coating and make the coating
easy to fall off. When used in the coating industry, water-based non-silicon defoamers can quickly eliminate the foam generated
by stirring, dispersing and other operations during the production process, and continue to play a foam-inhibiting role during
the storage and construction stages of the coating. In the production of water-based latex paint, adding an appropriate amount
of water-based non-silicon defoamer can make the surface of the latex paint smoother and more uniform in color, greatly
improving the product quality. In addition, since it will not have an adverse effect on the film-forming properties of the
coating and can ensure the stability of the various physical and chemical properties of the coating, it is favored by many
coating manufacturers.
III. Application in the food industry
In the food processing process, the presence of foam not only affects production efficiency, but also may threaten the quality
and safety of food. For example, in the fermentation process, a large amount of foam will hinder the transfer of oxygen,
affect the growth and metabolism of microorganisms, and cause abnormal fermentation process; when filling beverages,
foam will cause inaccurate filling volume, affecting the metering and packaging of products. Water-based non-silicon
defoamers have become an ideal choice for defoaming in the food industry due to their non-toxic, harmless, safe and
environmentally friendly characteristics. In the beer brewing process, it can effectively eliminate a large amount of foam
generated during the fermentation process, ensure the smooth fermentation, and will not affect the flavor and taste of
the beer; in the production of juice beverages, it can quickly eliminate the foam generated by stirring, homogenizing
and other operations, make the beverage clear and transparent, and improve the sensory quality of the product.
Moreover, water-based non-silicon defoamers meet the relevant standards of food additives, will not cause harm to
human health, and provide a guarantee for food safety production.
IV. Application in the papermaking industry
In the papermaking industry, the foam problem should not be ignored. In the pulping process, due to the large amount
of surfactants in the pulp, a large amount of foam is easily generated, which will affect the washing, screening and
bleaching effects of the pulp and reduce the quality of the paper; in the coating process, foam will cause uneven coating,
spots, stripes and other defects. Water-based non-silicon defoamers can quickly eliminate all kinds of foam in the
papermaking process, improve pulping efficiency and paper quality. In the waste paper deinking process, it can
effectively remove the foam on the surface of ink particles, separate the ink from the fiber better, and improve the
deinking effect; adding water-based non-silicon defoamers to the coating liquid can ensure the smooth coating process,
make the paper surface smoother and flatter, and meet the needs of different printing and packaging.
V. Application in other industries
In addition to the above industries, water-based non-silicon defoamers are also widely used in textile printing and dyeing,
metal processing, sewage treatment and other fields. In the textile printing and dyeing industry, it can eliminate the foam
generated during the dyeing process, avoid color spots, color flowers and other problems, and improve the uniformity and
brightness of dyeing; in the metal processing industry, it can effectively eliminate the foam in the cutting fluid and emulsion,
ensure the normal processing process, and extend the service life of the processing equipment; in the field of sewage
treatment, it can quickly eliminate a large amount of foam generated during aeration, improve the sewage treatment effect,
and improve the operating efficiency of sewage treatment equipment.
Water-based non-silicon defoamers play an important role in many industries with their unique performance and wide
applicability. With the continuous advancement of science and technology and the increasing requirements of various
industries for product quality, the application prospects of water-based non-silicon defoamers will be broader. In the future,
it is expected to be deeply applied in more fields and continue to innovate in technology to provide more efficient and
environmentally friendly solutions to solve foam problems.
