1. Basic Information

• Product Name: Defoamer
• Brand Model: C550
• Packaging Specification: 25 kg/blue barrel. The blue plastic barrel is made of strong material and has good sealing performance, which can effectively prevent the product from volatilizing and leaking during transportation and storage. It is also easy to carry and store, meeting the needs of different production scales of various enterprises.
• Main Ingredient: Silicone paste, with polysiloxane as the core active substance, and added with dispersants, stabilizers and other additives. It is mixed and formulated through a special process to form a stable defoaming system. Relying on the unique molecular structure of polysiloxane, it has excellent surface activity and can quickly play a defoaming role.

2. Product Characteristics

• Physical Properties
  • Appearance: Usually presents as a white or slightly yellow paste substance with uniform texture and a certain viscosity, which is convenient for accurate measurement and addition.
  • Solubility: Has good water solubility and can be uniformly mixed and diluted with water or thickened water; when diluted by adding 5% Tween, it can be better dispersed in systems with extremely high stability requirements without delamination, flocculation and other phenomena.
  • Melting Point and Boiling Point: As a mixture of multiple components, it has no fixed melting point and boiling point, but can maintain stable physical state and defoaming performance in the conventional production temperature environment (-10°C - 100°C).
  • Density: Approximately 1.0 - 1.2 g/cm³, which is similar to the density of media in most application scenarios such as water treatment and pulp black liquor, which is conducive to uniform dispersion in the system.
• Chemical and Application Properties
  • Wide Applicability: Suitable for multiple fields such as water treatment, pulp black liquor, petroleum fractions, inks, and oilfields. In water treatment, it can effectively eliminate foam generated in aeration, dosing and other links, ensure the smooth flow of the water treatment process, and improve the water purification effect; in pulp black liquor treatment, it can quickly eliminate foam generated due to organic matter decomposition, etc., and improve the efficiency of black liquor extraction and subsequent treatment; in petroleum fraction processing, it inhibits foam during distillation, extraction and other operations to ensure product quality and production safety; in ink production, it prevents foam from affecting the fineness, fluidity and printing effect of ink; in oilfield operations, it has a good elimination and inhibition effect on foam in drilling fluid, produced fluid and other links, ensuring the smooth progress of oilfield exploitation work.
  • Efficient Defoaming: Can quickly reduce the surface tension of foam, making the foam rupture rapidly. When added at the initial stage of foam generation, the amount of foam can be significantly reduced in a short time (5 - 10 minutes).
  • Long-lasting Foam Inhibition: The formed active molecular layer can adhere to the system for a long time, continuously inhibiting the generation of new foam. One addition can maintain the foam inhibition effect for 8 - 12 hours.

3. Action Principle

• Destruction of Foam Film: The polysiloxane molecules in the silicone paste have extremely low surface tension and can quickly adsorb to the gas-liquid interface of the foam, replacing the original surface active substances, destroying the elasticity and stability of the foam liquid film, making the liquid film thin and rupture, thereby achieving defoaming.
• Prevention of Foam Regeneration: After defoaming, some polysiloxane molecules will remain in the system, forming a very thin protective film, preventing surface active substances from accumulating at the gas-liquid interface, thereby inhibiting the generation of new foam.

4. Usage Methods and Precautions

• Usage Methods
  • Dilution Operation: According to specific application scenarios and foam conditions, dilute the C550 defoamer with water or thickened water, and the dilution ratio is usually between 1:5 - 1:20; for systems with extremely high stability requirements, dilute at a ratio of adding 5 parts of Tween to 100 parts of diluent. When diluting, slow stirring is required to ensure uniform mixing.
  • Addition Amount: The general addition amount is 0.1% - 0.5% of the total amount of the treatment system. In water treatment, it can be added at 0.1% - 0.3%; in pulp black liquor treatment, the recommended addition amount is 0.2% - 0.5%; in petroleum fractions, inks, oilfields and other fields, the addition amount can be adjusted according to the severity of foam, and the optimal dosage can be determined through small sample tests.
  • Addition Timing: Adding the defoamer before or just when the foam is generated can achieve the best defoaming and foam inhibition effect. For example, it can be added before the aeration link in water treatment, after the pulp black liquor cooking is completed, etc.
• Precautions
  • Storage Conditions: Should be stored in a cool, dry and well-ventilated warehouse, avoiding direct sunlight and high temperature. The recommended storage temperature is controlled at 5 - 30°C. During storage, the packaging barrel should be kept sealed to prevent the product from getting damp and contaminated. The shelf life of unopened products is 12 months, and it is recommended to use them up within 6 months after opening.
  • Safety Protection: It is recommended to wear protective gloves and goggles during operation to avoid direct contact with skin and eyes. If it accidentally contacts the skin, it should be rinsed with plenty of water immediately; if it enters the eyes, it should be rinsed with plenty of water immediately 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 failure.
