There are many types of water based universal defoamers, but what are they?

Introduction: There are many types of water-based universal defoamers, and people always use it to solve various items in daily life, but if people can tell what kind of types they can't say, then today I will tell you what is a water-based universal defoamer and what are the types? <>

The water-based defoamer is mainly prepared by dimethylsilicone silica emulsifier, and the water emulsion is dispersible defoamer made of emulsification technology, all the raw materials used are relatively environmentally friendly and free of toxins, and if it is poured out, the dispersion speed is very fast, the defoaming is fast and easy to foam, and the time is very unstable. It's not very high, it's very common in the market, so there are many people who buy it, and the reason why it's used is here. <>

Defoamer, also known as antifoam, is called antifoam digester, as the name suggests, it is used to eliminate foam, it is a very low surface expansion force and high surface activity, it can inhibit or eliminate foaming substances in the liquid, for example, there will be foam when some milk or soy milk is poured out, if the defoamer is used, then these foams are not, and it will not be easy to drink a lot of air, eggs are alkaline and baking soda cannot be used, everyone must remember. <>

As we all know, when making cakes, there will be a lot of foam, mainly because the gas rushes into the eggs. The cake is generally whipped with white peaches and eggs until it bubbles, and the cake is best to be lightly defoamed or baked in the oven, so that although the volume is a little smaller, but the final product is still relatively good, it is recommended that if you want to make the flour of the cake not foam in the process, the best reason is to stir it gently, and don't let the air flow in. Defoamers are convenient for many people.

There are emulsifiers, antifoaming agents, digestive agents, liquid water agents, solid water agents, etc., and there are many types, each of which will produce different effects.

There are solid, liquid, mineral oil, silicone, polyether, which are the more common types on the market.

There are many, some solid, some liquid, some mineral, some polyether, and some emulsified type.

There are many uses of water-based defoamers, such as: coatings, inks, construction, water treatment, metal processing industry, industrial cleaning, papermaking, adhesives, etc., because there are too many uses, they will not be introduced one by one, basically it can be used in various water-based system products. Modified silicone defoamer refined from a variety of modified polydimethylsiloxane and other defoaming components, which can be used to remove foam from aqueous systems.

The water-based defoamer is a water-emulsion dispersed defoamer made of dimethicone, silica, emulsifiers, etc., and is designed by emulsification technology. All raw materials and links are non-toxic, with the characteristics of fast dispersion, fast defoaming, long foam inhibition time, stability and non-delamination.

There are many types of water-based defoamers, each of which has very different uses, which can be roughly divided into three categories, silicone defoamers: this type of defoamer has strong defoaming ability, low addition amount and low cost. Mineral oil defoamers:

This kind of defoamer has both defoaming and foam inhibition pin leakage energy, good compatibility with coatings, and is not easy to produce shrinkage holes, but it is generally not used in water-based wood paint and floor paint loss, which affects the resistance. Polyether defoamer: This type of defoamer has good water dispersibility and high temperature resistance.

When the defoamer reacts with the foaming solution, on the one hand, the defoamer will lose its effect, and on the other hand, it may produce harmful substances and affect the growth of microorganisms.

0. Low volatility and long action time.

The first step is to determine whether the system that needs to use the defoamer is water-based or oil-based. For example, in the fermentation industry, oil-based defoamers should be used, such as polyether modified silicon or polyether. The water-based coating industry requires water-based defoamers and silicone defoamers.

Select the defoamer, compare the dosage added, and get the most suitable and economical defoamer product in the reference**.

Dosage of defoamer.

1. Alcohol defoamer: When alcohol defoamer is used, the dosage is generally within the limit.

2. Oil-based defoamer: the addition amount of oil-based defoamer is between, and the addition amount of fatty acid ester defoamer is between.

3. Amide defoamer: The effect of amide defoamer is relatively good, and the addition amount is generally within the limit.

4. Phosphoric acid defoamer: Phosphoric acid defoamer is most commonly used in fibers and lubricating oils, and the addition amount is between.

5. Amine defoamer: Amine defoamer is mainly used in fiber processing, and the addition amount is.

6. Ether defoamer: Ether defoamer is used more in papermaking, printing and dyeing, cleaning, and the addition amount is like a shirt.

Pros and cons: 1.Silicone-based defoamers:

This defoamer is easy, relatively the cheapest, although cheap, but the effect is very good, the defoaming speed is fast, the foaming time is long-lasting, non-toxic and harmless is a good defoamer for most industrial defoaming. The method of use is also very simple, that is, it is not easy to store and easy to deteriorate, and it is incompatible with a small number of systems.

2. Polyether defoamer: polyether defoamer is the most stable type, and most of the system compatibility is the most stable defoamer.

3. High-carbon alcohol defoamer: It is a relatively effective defoamer, and some foams that are difficult to eliminate can be eliminated with high-carbon alcohol defoamer.

4. Silicon defoamer: it can not only eliminate foam but also inhibit the generation of foam, and is one of the few defoamers that can fundamentally solve industrial foam.

5. Polyether modified silicon: it combines the advantages of the first two defoamers, and is also non-toxic and harmless, and is a cost-effective product.

When the concentration of liquid surfactant is high, excessive foaming is often produced. To reduce the amount of this foam, we can use defoamers. A defoamer is a surfactant that is able to break the tension on the surface of a liquid and make the bubbles burst and disappear, thereby reducing or preventing the formation of foam.

A water-based defoamer is a kind of defoamer suitable for water-based systems, usually composed of surfactants, stabilizers, co-solvents, etc. It is mainly used in the following areas:

1.Cosmetics and personal care products: Adding water-based defoamers to shampoos, shower gels, toothpastes, and more can reduce foaming while improving product stability.

2.Industrial cleaning: Water-based defoamers are also widely used in industrial cleaning agents, such as metal cleaning, car cleaning, printing press cleaning and other fields, to reduce foam while ensuring cleaning effect.

3.Paints and coatings: Adding water-based defoamers to products such as water-based painted paints and wall paints can reduce foam and prevent affecting the quality and effectiveness of coatings.

In conclusion, water-based defoamers have a wide range of uses and can play a role in many fields.

A water-based defoamer is an aqueous defoamer that has been emulsified with emulsifiers and other fillers. In industrial production and daily life, many industrial raw materials and detergents and other liquid cleaning products are prone to foam due to the addition of their own surfactants. Many foaming stock solutions are in liquid form, so it is a good choice to use a water-based defoamer that is well compatible with water.

Therefore, water-based defoamers are widely used in metal processing, water treatment, textile industry, petrochemical industry, surfactant, daily chemical products, metal cleaning industry, detergent, water-based coatings, resin and other ear-deficient industries with excellent water solubility, fast dispersion speed, fast defoaming, long foaming time, stable and non-stratification.

The water swimming companion defoamer can be used in coatings, detergents, pharmaceuticals, petroleum, water collapse rules and printing and other fields, widely used, and its main purpose is to achieve defoaming and foam inhibition effects.

Water-based paint defoamer is a surfactant that reduces the surface tension and viscosity of the coating, thereby reducing the formation of bubbles and foam on the surface of the coating. According to its nature and use, it can be divided into the following categories:

1.Polysiloxanes: This is a commonly used silicone surfactant with good defoaming properties and dispersibility, which can be used in various water-based coatings.

2.Palmitates: This is an excellent defoamer for water-based coatings such as emulsions and acrylic paints, and can play a role in thickening and preventing delamination.

3.Polyether: This is a non-ionic surfactant with good defoaming effect and stability, suitable for a variety of water-based coatings and inks.

4.Low-foaming polyether: This is a defoamer specially used for high-speed blue gear stirring resistance and high shear application, which can effectively reduce surface tension and viscosity, and inhibit the formation of foam and bubbles during the rolling process.

5.Hydroxy fatty acid salts: This is a natural foaming agent that can be used in a variety of water-based coatings and inks and has good biodegradability.

It should be noted that different types of defoamers have different scope of application and application methods, and it is recommended to conduct a small sample test before use to determine the best addition amount and construction process. In addition, during storage and use, attention should also be paid to keeping it dry, moisture-proof and avoiding the influence of heat and other factors to ensure its use effect and safety.

Water-based paint defoamer is used in high-build water-spoiled coatings, high-viscosity elastic coatings (elastic paints), high-build high-density latex paints, single-layer coatings, varnishes, elastic brushed emulsion paints, water-based epoxy coatings, water-based paint mixing, water-based coatings, and special defoamers for water-based coatings.
