(2) Chemical and Application Properties
Efficient Defoaming and Foam Inhibition: It can quickly eliminate the generated foam in the system at both normal temperature and high temperature, and has a significant inhibitory effect on the subsequent generation of foam. For example, in the high - temperature environment of petroleum extraction or the complex system of papermaking black liquor treatment, it can effectively control foam and ensure the smooth progress of the production process.
Wide - range Adaptability: It has a wide adaptation range to acidity and alkalinity, and can maintain stable defoaming performance in a relatively wide pH range (generally pH 3 - 12); at the same time, it also has strong adaptability to temperature and can normally play a role in the temperature range of about 0 - 150°C, meeting the needs of different working conditions in different industries.
Good Dispersibility: It can be quickly and uniformly dispersed into various application systems, such as the reaction liquid in the chemical distillation process and the dye liquor in textile printing and dyeing, ensuring that the defoaming and foam - inhibiting effects can be exerted in a timely and effective manner throughout the system.
Wide Application Fields: It is suitable for multiple industries such as papermaking, cleaning, chemical industry, petroleum, water treatment, and textile, and can meet the diverse defoaming needs of different industries due to differences in production processes and material characteristics.
III. Action Principle
Reduce Surface Tension: The polysiloxane part in the organosilicon molecule will be quickly adsorbed to the gas - liquid interface of the foam, significantly reducing the surface tension of the foam liquid film, making the foam film wall thinner and less stable, and finally leading to the rupture of the foam.
Destroy Foam Elasticity: Its molecules can penetrate into the foam film, interfere with the orderly arrangement of surfactant molecules in the foam film, destroy the elastic structure of the foam film, and make the foam more likely to rupture when subjected to external disturbance or its own gravity.
Inhibit Foam Generation: In the system, organosilicon molecules will occupy the gas - liquid interface position where foam may form first, preventing foaming substances such as surfactants from accumulating at this position, thereby inhibiting the generation of new foam from the source.

V. Usage Methods and Precautions
(1) Usage Methods
Addition Amount: Generally, the addition amount is 0.05% - 0.5% of the total amount of the treatment system. The specific addition amount needs to determine the optimal dosage through small - scale tests according to factors such as the severity of foam in the actual production process and the nature of the system.
Addition Method: The defoamer can be slowly added directly to the production system, or it can be diluted with an appropriate amount of water or the solvent in the system before adding. In order to ensure that the defoamer can be uniformly dispersed, it is recommended to add it under stirring.
(2) Precautions
Storage Conditions: It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high temperature. The storage temperature is recommended to be controlled at 5 - 35°C. After opening, it should be sealed in time to prevent the product from volatilizing or deteriorating due to pollution.
Safety Protection: It is recommended to wear gloves and goggles during operation to avoid direct contact with skin and eyes. If it accidentally comes into contact with the skin, rinse immediately with plenty of water; if it enters the eyes, rinse immediately with plenty of water and seek medical attention in time.
Compatibility Taboo: Avoid direct mixing with strong oxidants, strong acids and strong alkalis. Before using it with a new system or chemicals, it is recommended to conduct a small - scale compatibility test first to confirm that there will be no adverse reactions such as precipitation, discoloration, and reduced defoaming effect.
