Are there any cheaper defoamers?

Defoamers, also known as defoamers, are food additives that reduce surface tension during food processing, inhibit foam production or eliminate foam that has already been produced. There are 7 kinds of defoamers licensed for use in China, including emulsified silicone oil, high-carbon alcohol fatty acid ester compound, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene amine ether, polyoxypropylene glycerol ether and polyoxypropylene polyoxyethyleneglycerol ether, and polydimethylsiloxane.

Most of the defoamers are liquid compound products, which are mainly divided into three categories: mineral oils, silicones, and polyethers. Mineral oil defoamers are usually composed of carriers, active agents, etc.

The carrier is a substance with low surface tension, and its role is to carry and dilute, and the commonly used carriers are water, fatty alcohols, etc.; The function of the active agent is to inhibit and eliminate foam, and the commonly used ones are wax, aliphamids, fats, etc. Silicone-based defoamers generally include polydimethylsiloxane, etc. Organosilicon defoamers have poor solubility, fast defoaming speed and good foam inhibition at room temperature, but delamination occurs at high temperature, slow defoaming speed and poor foam inhibition.

Polyether defoamers include polyoxypropylene, ethylene oxide, glycerol ether, etc. Polyether defoamers have the characteristics of long foam inhibition time, good effect, fast defoaming speed and good thermal stability.

HY-1040C defoamer is quite cost-effective.

You can take a look at Fujian West Defoamer, the manufacturer of defoamer.

Search more, I remember that there is a Zhongdi Mei.

Generally, imported products are better, and the effect is relatively high, and they can also be purchased online, market, etc.

Defoamer, also known as antifoam, as the name suggests, is to deal with the harmful foam produced in the chemical industry, in general, in short, the defoamer has the effect of foaming, deaeration and foam inhibition, and its use is very wide, mainly reflected in the following aspects:

Defoamers typically contain hydrophobic precipitation silica dispersed in mineral or silicone oil. In fact, the larger the particle size of the silica used in the defoamer, the easier it is to precipitate, especially in low-viscosity dispersion systems. The addition of hydrophobic fumed silica can completely prevent or significantly reduce this sedimentation process.

The silanol group in fumed silica is like a lot of needles, puncturing the bubbles, so that the small bubbles converge into large bubbles, overflow the system, and achieve the effect of defoaming. In some defoaming systems, hydrophobic fumed silica can also be a silica component with defoaming effect, fumed silica plays a role in thickening and anti-settling in defoamers, and more importantly, enhancing defoaming ability and improving foam inhibition ability.

Defoamers are additives that eliminate foam. In the production and application process of coatings, textiles, medicine, fermentation, papermaking, water treatment and petrochemical industries, a large amount of foam will be generated, which will affect product quality and production process. Based on the suppression and elimination of foam, a specific amount of defoamer is usually added to the production process.

What is a defoamer? A key feature of all defoamers is that they are incompatible with foaming fluids. An overly compatible defoamer does not expand sufficiently into the foam film layer, it is present throughout the coating film; The defoaming effect is either very low or non-existent.

Excessive incompatibilities can in turn lead to problematic foam, such as cloudiness or cratering. Therefore, choosing the right defoamer is a "balancing act" between compatibility and incompatibility.

In view of this, the choice of defoamer depends on the time of addition, the duration and the method of incorporation (shear force and dosage in the coating formulation. All of these parameters affect the distribution and therefore the droplet size. Defoamers in coating formulations.

They affect its effectiveness. If the dispersion process is inefficient and results in excessive droplet formation, surface defects can occur in the coating. If the dispersion is too large, the defoamer droplets are too small and their behavior is too "compatible" in the coating formulation, reducing the effectiveness.

For defoamers with particularly high activity that exist as concentrates, defoamer droplets need to be generated in situ. This can be caused by, for example, the delicate distribution of defoamers in paint formulations in the abrasives by means of high-shear dispersion equipment. In the case of defoamer emulsions, where the emulsion droplets are already finely distributed in water, the defoamer can be added to the coating formulation at the low shear forces typically used during paint mixing.

With so many different foaming fluid systems, there is no "one-size-fits-all" defoamer that fits all formulations. To ensure that the right product can be supplied for any purpose, a range of defoamers is required. The defoaming effect can be finely adjusted by varying the dosage.

In general, the more defoamer you use, the better the defoaming effect. However, this may also increase the defect or make it more apparent. Reducing the dose can prevent film problems, but in some cases, defoaming may be inadequate.

The term "defoaming" is often used to describe the removal of air bubbles from the foam. However, in some cases, a distinction should be made between "defoaming" and "air release". First, the bubbles need to reach the surface.

Removing foam bubbles from a surface is called defoaming. Defoamers are only effective at the surface to eliminate air bubbles on the surface. In contrast, air releasers work throughout the working system.

Here are some factors to consider when purchasing a defoamer:

Disperse: Determine where you need to defoam, such as industrial production, coatings, detergents, water treatment, etc. Different types of defoamers are required for different occasions.

Ingredients: Defoamers come in a variety of ingredients, including silicones, phosphates, amino acids, and more. When choosing a defoamer, you need to consider whether its composition is relevant to the foam you need to eliminate and whether it is safe.

Effect: The effect of the de-drying or foaming agent is an important consideration in the selection. Different types of defoamers have different defoaming effects, and they need to be selected according to the actual situation.

Brand and**: The brand and ** of the defoamer are also important considerations in the selection. Choosing a reputable brand and the right ** can ensure that your defoamer has good performance and quality.

Compatibility: Defoamers are generally compatible with other chemicals, so when choosing a defoamer, consider their compatibility with other chemicals to ensure that they do not affect the performance of other chemicals.

In conclusion, when selecting a defoamer, there are several factors that need to be considered on a case-by-case basis to ensure that the selected defoamer has good performance and quality.

It is necessary to choose a defoamer that defoams quickly, inhibits foam for a long time, and has excellent defoaming and foam inhibition properties.
