What are the precautions for silicone defoamer?

Silicone defoamer is more important in the chemical industry, coatings, textiles, and other industries, and in the industrial processes used, silicone resin defoamer should pay attention to the method precautions, What are the precautions for silicone defoamer?

1. How to apply silicone defoamer in the production process?

(1) Choose the right silicone defoamer:

According to the required application and field, we should choose the suitable silicone defoamer. Different products have different characteristics and uses, and they can be selected according to production needs and performance requirements. Different from mineral oil, silicone resin defoamers have very low surface tension, which is slow to frost and high temperatures, and are easily crushed. If the defoamer has been frozen must be vigilant to frost, and test before manipulation.

(2) Determine the amount of use: 

According to the actual needs and relevant process parameters to determine the amount of defoamer. In general, the initial use of the amount can be estimated based on experience, and then gradually adjusted according to the actual results.

(3) Pre-dilution: 

The silicone defoamer and water or other solvents for pre-dilution. In the process of dilution, it should be stirred constantly to ensure that the defoamer is fully dissolved. Because the emulsion is not uniform will be easy to produce a layered environment, affecting the antifoam agent manipulation results, it is needed to avoid frequent emptying.

(4) Join the production process:

According to the process needs, at the appropriate time, a pre-diluted silicone defoamer was added to the production process. According to the actual need to choose to join directly or to spray, slide into the way to join.

(5) Pay attention to the use of skills:

In the use of the process, we must pay attention to the timely mixing, so that the antifoam agents are distributed. According to the actual situation, the stirring speed can be adjusted to ensure the uniform dispersion of the defoamer.

(6) Observe the effect:

After adding the antifoam agent, it is needed to closely observe the defoaming effect. If necessary, the amount of defoamer can be adjusted to achieve the desired defoaming effect.

(7) Pay attention to safety: 

Silicone-based defoamers should pay attention to protective measures during use, and avoid contact with eyes, skin, and respiratory tract. If contacted inadvertently, it should be rinsed with water immediately, and if there is any serious discomfort, medical attention should be sought as soon as possible.

(8) Storage and maintenance:

After use, keep the silicone defoamer in a sealed place, and avoid direct sunlight and high-temperature environments. If precipitation or deterioration occurs in the make, it is recommended to replace it with a new antifoam agent.

To summarize, silicone antifoam agent is a very practical chemical additive, can help to reduce the production process foam generation, and improve production efficiency. Simple to use, but in the use of the process need to pay attention to the safety and effectiveness of the observation, to ensure the quality of the product and the smooth progress of production.

2. How to store silicone defoamer?

Silicone defoamer is a common type of defoamer, its correct storage and use is the key to ensuring product quality and safety. Prolonged violent oscillation or strong shear (such as manipulation of mechanical pumps, homogenizers, etc.) or stirring will break and destroy the stability of the defoamer, so pay attention to the storage of silicone resin defoamer. The following are the correct storage methods and precautions for silicone defoamer:

(1) Storage environment: Silicone defoamer should be stored in a dry, cool, and well-ventilated storage room. Avoid direct sunlight and high-temperature environments to prevent product quality damage.

(2) Packaging containers: Silicone defoamers are usually supplied in sealed packaging containers (e.g., plastic bottles, buckets, or drums). When storing, it is needed to make sure the containers are intact and remain sealed to prevent moisture and impurities from entering.

(3) Avoid mixing: Silicone defoamers should be kept stored separately from other chemicals to prevent mutual contamination or chemical reactions. It is needed to clear labeling and categorization in the storage area is recommended.

(4) Prevent freezing: Some silicone defoamers may freeze or solidify at low temperatures. If the storage environment is expected to be exposed to low temperatures, measures should be taken to prevent icing and to return it to a liquid state if needed.

(5) Caution about sources of ignition: Since silicone defoamers are usually flammable substances, storage areas should be kept away from open flames, high temperatures, and sources of ignition. It is needed to ensure that the storage area meets fire safety requirements and complies with relevant fire regulations.

(6) Compliance: When storing and using silicone defoamers, follow local regulations and safety practices. It is needed to know the product's Safety Data Sheet (SDS) and follow the recommended safe handling procedures.

(7) Periodic Inspection: Periodically inspect the storage conditions and packaging containers of the silicone defoamer to ensure that there are no leaks, damage, or deterioration. If any abnormality is found, appropriate measures should be taken promptly, such as replacing the container or consulting the supplier.

In conclusion, proper storage methods and precautions can ensure the stability and safety of silicone defoamers. Following storage conditions and safe operating procedures will help protect product quality, reduce safety risks, and extend the effective service life of the defoamer. If there are any questions or special circumstances, it is recommended to consult the supplier of the organosilicon defoamer or professional advice.

XJY-6010/XJY-6011/XJY-6012 Methyl MQ Silicone Resin for defoamer is a solid powder resin. This resin provides good antifoaming, hydrophobic, and water-repellent properties.

3. What is the dilution method for silicone defoamer?

Silicone resin defoamer can be diluted at the moment of use, but the stability of the defoamer at the same time dilution will be sharply reduced as a result, such as the occurrence of delamination, so it is recommended to try to manipulate the thickening agent for dilution.

So silicone defoamer is not recommended to use water to open thinning, because if you use water to open thinning, it will break the viscosity system of the defoamer itself, if the control is not good, it will produce delamination, or even emulsion-breaking situation, such as this defoamer performance will be greatly reduced.

Silicone resin defoamer must pay attention to adjust the PH value of the system because the PH value will affect the true system of acidity and alkalinity, and later manipulation of the results, it is recommended that we use PH test paper to detect the acidity and alkalinity; then it is necessary to correct regularly if long time not corrected, it will lead to the measurement of the effectiveness of the inaccuracy and the measurement of the time to stir not evenly. If it is not even, the effect is not the same in different locations, and it will also be affected by the temperature.

4. How to make silicone defoamer perform better?

Silicone defoamer has been widely used in many aqueous systems such as chemical, paper, coating, food, textile, pharmaceutical, and so on (such as carpet extractors) with its wide performances, excellent defoaming performance, good stability, low surface tension, and environmental protection, and many other advantages.
