Organic silicone defoamer is a defoamer made from polydimethylsiloxane (silicone oil) as the main component, combined with emulsifiers, dispersants, stabilizers and other additives through special processes. With its unique chemical structure, it can quickly defoam and sustainably inhibit foaming in both water and oil systems, and is widely used in fields such as chemical engineering, food, medicine, papermaking, textiles, and wastewater treatment.

The working principle of decolorizing agents can be divided into the following categories based on their types:
1. Flocculation decolorizing agent: This type of decolorizing agent mainly forms flocs through chemical reactions, enhances the adsorption capacity of pigments, oxides, and impurities in oil products, and then achieves decolorization and purification through physical filtration. Flocculation decolorizer is usually a quaternary ammonium cationic polymer compound, which has multiple functions such as decolorization, flocculation, and degradation of CODcr.
2. Oxidation decolorizer: using oxidizing substances such as sodium hypochlorite, potassium permanganate, ozone, etc., to remove chromaticity by destroying colored groups. Oxidative decolorizers are suitable for various types of dyes and have the characteristics of efficient decolorization and rapid reaction.
3. Adsorption decolorizer: This type of decolorizer usually uses materials such as activated carbon, clay, or adsorption resin to remove impurities and oxides from oil products through physical adsorption. Adsorbent decolorizers can directly filter out impurities and oxides in oil products through filtration, turning blackened oil products into light colored transparent liquids.
| Appearance | Colorless or light colored transparent viscous liquid Light colored or light yellow transparent viscous liquid |
| Solid Content | ≥50% |
| Viscosity（map.s,20℃） | 10-500 |
| pH（30% Aqueous solution） | 2.0-5.0 |
1. Efficient decolorization
The decolorization rate of water-soluble dyes (such as reactive dyes, acid dyes, direct dyes) in wastewater from printing and dyeing, papermaking, electroplating, etc. can reach over 90%, and some products also have significant effects on oil soluble pigments.
2. Multi functional collaboration
It has the functions of flocculation, COD (chemical oxygen demand) removal, and heavy metal ion reduction, which can simplify the treatment process and reduce overall costs.
3. Wide applicability
PH adaptability: Most products are effective within the pH range of 4-11, and some models can be used under strong acid or alkali conditions.
Temperature adaptability: It can maintain stable performance within the range of room temperature to 60 ℃, suitable for water treatment needs in different regions and seasons.
4. Easy to operate
Liquid products can be directly diluted and added, while solid products dissolve quickly without the need for complex equipment and are easily compatible with existing treatment processes such as coagulation sedimentation and air flotation.
5. Environmental protection and safety
Some products contain inorganic or natural ingredients (such as polyaluminum chloride and activated carbon), with no secondary pollution; Polymer products should pay attention to residual monomer toxicity and prioritize low toxicity or non-toxic models (such as food grade decolorizers).
