Will pesticide defoamers affect the medicinal effect of the product?

No, as an adjuvant, pesticide defoamer only plays a role in defoaming and foaming, and does not affect the pesticide itself.

Pesticide defoamer will not affect the effect of pesticides, only play a defoaming role.

No, the defoamer only acts on the foam, and its energy efficiency dissipates after the effect, and does not affect it.

Hello, choosing a pesticide defoamer with good compatibility and good chemical stability and adding it under the correct guidance will not affect the medicinal effect of the product.

Pesticides are usually made of various surfactant liquids as raw materials, and general pesticides are very easy to foam in the process of production, processing, transportation and use due to grinding, stirring, high-speed shearing, shaking and impact. Foam has always been a thorny problem, most occasions do not want pesticides to produce foam, it is not good for them, so pesticide defoamers recommend the following countermeasures for you to solve the foam problems encountered.

In the process of producing pesticides, it is necessary to carry out high-speed shearing, grinding, shaking, stirring, etc., which brings in a lot of air, and also generates too much heat, and if the surfactant is not selected properly or the amount is used, it will produce foam.

Dachuan pesticide defoamer is made of silicon polyether with a variety of active additives through special technology. It is easy to disperse and self-emulsifying in aqueous systems. Easy to use, whether you are in the process of pesticide processing, transportation and use, you can achieve long-lasting anti-foam performance.

Pesticide defoamer, as the name suggests, is mainly used to remove pesticide foam, and is generally used in the production process. Because too much foam in the process of producing pesticides will affect production, and will also affect the use of pesticides.

Pesticide defoamer is made of specially modified polyether and fluorine-containing raw materials through a special process. It can quickly defoam and long-term foam inhibition, chemically stable, soluble in water, can be used in a wide range of temperatures and various harsh foaming systems, and will not affect the basic properties of foaming systems. And the amount of pesticide defoamer added is not much.

Normally, it can be added according to the proportion of weight, which is cost-effective.

It does not affect the basic properties of the foaming system, and the defoaming and foaming inhibition effects are good, and the dosage is small; Good diffusion, permeability, heat resistance; Non-physiologically active, non-flammable and non-explosive, high safety; Chemically stable and shear resistant.

Pesticides include herbicides, insecticides, fungicides, etc., generally complex organic matter, in order to make it evenly distributed on crops, surfactants must be added to prepare wettable powder or oil-in-water emulsion. Foam will be produced when used in dilution. The flotation effect of the foam reduces the uniformity of the aqueous dispersion of the pesticide, affects the efficacy, and interferes with the spray operation.

The new technology of pesticide defoamer is silicon polyether product, aqueous agent generally focuses on compatibility and foam inhibition, suspension agent generally focuses on rapid defoaming and certain foam inhibition, the choice of defoamer must find the right service company, has a certain technical strength.

Pesticide in the emulsification process to add surfactant and produce a large amount of foam, thus causing the difficulty of discharging and farmers use the foam is too large to affect the pesticide spraying and the development of water-soluble defoamer.

It is divided according to the shape of the product.

oily type (such as linseed oil, mineral oil, vegetable oil, etc.);

Solution type (such as polyether, partial alcohol, silicone oil solution, etc.);

Emulsion type (such as emulsified silicone oil, emulsified mineral oil, etc.);

Composite type (such as silicone-containing mineral oil, silicone oil-modified polyether, etc.);

Solid type (e.g., monoglycerides stearate, powdered hydrophobic silica, defoaming rods, etc.).

In general, the initial amount of pesticide-specific defoamer is as follows: The subsequent addition amount can be adjusted appropriately according to the actual defoaming situation.

There are many types of defoamers, which are generally organic matter, silica, organosilicon, etc., and are divided into emulsified and unemulsified. When choosing a defoamer for water-based coatings, we should pay attention to: (1) strong defoaming ability; (2) Good stability; (3) It does not affect the luster; (4) There are no obstacles such as recoating.

It is recommended that you use the high-speed stirring method to test the defoaming ability of the defoamer. Fix parameters such as speed, stirring time, dosage, viscosity, etc., and then compare the height of the foam and the time to eliminate.

Generally, high-viscosity latex paint, due to the difficulty of defoaming, there are many foam stabilization factors, and the dosage is slightly more. Low-viscosity latex paints or water-soluble coatings, especially water-soluble coatings, can be appropriately reduced due to the presence of a certain amount of co-solvents, generally enough. Other water-based paints or resins, generally around.

Anyway, the higher the dosage, the better, more will cause shrinkage holes, oil splashes and other paint diseases, and there are more silicon-containing defoamers, which will also affect the recoatability.

Most defoamers cannot be added directly to diluted water-based coatings, and are generally added when the viscosity of the resin or coating is high and has good dispersion. It is also best to add it in two parts, one in the abrasive and the other in the lacquer, adding half at each stage.

The addition amount of special defoamer for pesticides is generally the total foaming system, and the specific economical dosage needs to be measured by actual testing.

The amount of aqueous pesticide added is 1/1000, and the amount of suspension agent is larger, because it will have stronger foaming in case of high temperature, and it should be added to about 3/1000.

The pesticide-specific defoamer is added to the foaming system to ensure its uniform dispersion. If dilution is to be made, it is best not to store the dilution for more than 24 hours.

For systems with a high foaming temperature (60), it is recommended to add a defoamer or diluent to the system before 60 and disperse evenly to maximize its effectiveness.

According to the viscosity, temperature and stirring of different foaming systems, in units of 10ppm, choose a more economical dosage, generally speaking, the dosage of 30-200ppm can ensure the ideal defoaming effect, some industries such as coatings, biological fermentation may need to use 2-5%, Dachuan hopes to help you.

There is a little harm to the human body.

Defoamers are a little harmful to the human body, but moderate consumption will not affect the body. Defoamer is a kind of food additive, mainly used for tofu and other easy to foam food processing, since it is a food additive, to a certain extent to the body has an impact, it has a limit on the amount and variety.

Defoamer is generally harmless, it is mainly a chemical additive, to help enterprises make products better.

Our company is an enterprise that produces defoamers and develops defoamers, and hopes to work with you to ** defoamers.
