It enables flexible use, precise control of single-dose usage, reduces storage pressure and capital occupation for small-volume users, and facilitates short-distance transportation and rapid turnover.
- 200 kg/barrel: A large-capacity package, mainly designed for large-scale production enterprises or users with long-term and stable high usage. It can reduce the frequency of packaging replacement, lower procurement, logistics, and packaging disposal costs, and is more compatible with continuous and large-scale production scenarios to improve supply chain efficiency.
Main Component
The core component is organosilicon (usually based on polydimethylsiloxane as the active substance, combined with special emulsifiers, stabilizers, and other auxiliary ingredients). Organosilicon has the characteristic of low surface tension, which can quickly break down foam structures and is the key to achieving efficient defoaming. It also has good chemical stability and compatibility, enabling stable performance in multiple systems such as detergents and textile dyeing without adverse reactions with other components in the system.
2. Product Characteristics
Efficient Defoaming in Multiple Scenarios, Targeted Foam Solutions
DC-544 exhibits excellent defoaming performance in various application scenarios:
- For detergent and liquid detergent systems, it eliminates foam generated during stirring and dissolution, avoiding issues such as product overflow during filling and excessive foaming affecting cleaning efficiency during use.
- In the textile field, it is especially suitable for the high-speed operation of jet dyeing machines. It can quickly break down stubborn foam in dye liquor caused by mechanical stirring and high temperatures. Meanwhile, in foamy environments of general textile and carpet dyeing, it can continuously inhibit foam regeneration to ensure stable processes.
Adaptable to Textile Dyeing Processes, Ensuring Dyeing Quality
As an effective dedicated antifoam for jet dyeing machines, DC-544 not only defoams in textile dyeing but also prevents defects such as fabric color unevenness and stains caused by foam entraining dye liquor. It ensures uniform distribution of dyes on the fabric surface, improving dyeing uniformity and color fastness. At the same time, it does not react with dyes or fabric fibers, and will not affect the hand feel, luster, and other physical properties of textiles, meeting the quality requirements of textile production.
Good System Compatibility, No Adverse Interference
- In detergent and liquid detergent systems, it has good compatibility with surfactants and additives. It will not cause delamination or precipitation of detergents due to the addition of antifoam, nor will it affect the cleaning power, stability, or appearance (e.g., transparency, color) of the product.
- In textile dyeing systems, it is compatible with dyes and dyeing auxiliaries (such as leveling agents and fixing agents), and does not interfere with the dyeing reaction process, ensuring that the performance of the final product is not affected by the addition of antifoam.
Strong Chemical Stability, Adapting to Process Environments
It can withstand normal to medium temperatures in detergent production and medium to high temperatures (usually 40–130°C) in textile dyeing processes. It is not easy to decompose or become ineffective within the range of temperature fluctuations, and there will be no problems such as emulsion delamination or demulsification, maintaining stable defoaming effects to meet the process environment requirements of different application scenarios.
3. Application Fields
Detergent and Liquid Detergent Industry
Applicable to the production and application of various detergents (e.g., laundry detergents, dishwashing detergents) and liquid detergents:
- During production, adding it can eliminate foam generated by raw material mixing and stirring, facilitating product filling and metering.
- During use (e.g., laundry, dishwashing), it can inhibit excessive foam generation, avoiding foam adhering to clothing and affecting rinsing efficiency, or causing incomplete rinsing of tableware with residual foam, thereby improving product user experience.
Textile Dyeing Field
- Dedicated for Jet Dyeing Machines: Compatible with the high-efficiency operation mode of jet dyeing machines. It solves the problem of a large amount of foam generated in dye liquor under high-pressure jetting and high-speed stirring, prevents foam from hindering dye liquor circulation, avoids uneven dyeing of fabrics caused by foam wrapping, ensures the continuity and stability of the jet dyeing process, and improves production efficiency.
- General Textile and Carpet Dyeing: In the dyeing process of conventional textiles (e.g., cotton, chemical fiber, blended fabrics) and carpets, whether it is beam dyeing, pad dyeing, or exhaust dyeing, adding DC-544 can effectively defoam and inhibit foam as long as there is foam interference. It ensures dyeing quality, and is especially suitable for carpet dyeing scenarios where the structure is complex and foam is easily entrained.
Slurry Degassing Link
Used for degassing textile slurries (e.g., starch slurries and chemical slurries for warp sizing). It eliminates bubbles generated during slurry preparation due to stirring and dissolution. The degassed slurry can adhere more uniformly to the yarn surface, avoiding incomplete size films and increased yarn breakage rate caused by bubbles, and improving the stability of subsequent textile weaving processes and product quality.
4. Usage Methods
Addition Timing
- Detergents/Liquid Detergents: It is recommended to add after the late stage of raw material mixing and before product homogenization. Adding at this time can specifically eliminate foam generated during the mixing process and facilitate full integration of the antifoam with the system. If foam occurs suddenly during production, it can also be added supplementary, but the addition speed should be controlled to avoid affecting product stability due to local high concentration.
- Textile Dyeing: It is recommended to add preventively after the dye liquor is prepared and before it is injected into the dyeing machine, or add supplementary in a timely manner when foam is found during the dyeing process. For jet dyeing machines, it is recommended to add at the initial stage of dyeing cycle startup to ensure that the antifoam is dispersed in the dye liquor in advance to cope with foam generated during subsequent high-speed operation.
- Slurry Degassing: Add after the slurry is prepared and before the degassing process. Allow the antifoam to disperse fully before entering the degassing equipment to help improve degassing efficiency and eliminate fine residual bubbles.
Addition Amount
The addition amount needs to be flexibly adjusted according to the specific application scenario, total system volume, and foam severity:
- Detergent/liquid detergent systems: The recommended addition amount is generally 0.05%–0.2% of the total mass of the system, which can be adjusted according to the surfactant content and stirring intensity.
- Textile dyeing systems: For jet dyeing machines, the recommended addition amount is 0.1%–0.5% of the total volume of the dye liquor; for general textile and carpet dyeing, it can be added at 0.08%–0.4%.
- Slurry degassing link: The recommended addition amount is 0.05%–0.3% of the total mass of the slurry.
For the first use, it is recommended to conduct small-batch tests to test the defoaming effect, system stability, and final product performance under different addition amounts, so as to determine the optimal addition amount and balance defoaming efficiency and cost.
Mixing Method
- Direct addition: If the system is fully stirred (e.g., detergent mixing tanks, dyeing machine circulation systems), DC-544 can be directly and slowly added to the system, and stirred for 5–10 minutes with existing mixing equipment to ensure uniform dispersion of the antifoam.
- Diluted addition: If the system viscosity is high (e.g., thick slurries, high-concentration detergents), the antifoam can be diluted 1–5 times with an appropriate amount of system solvent (e.g., deionized water, dyeing process water) before addition. This reduces the viscosity difference, improves dispersion efficiency, and avoids local agglomeration affecting the defoaming effect.
5. Storage Conditions
Environmental Requirements
Store in a cool, dry, and well-ventilated warehouse, avoiding direct sunlight and high-temperature environments (the recommended storage temperature is 5°C–35°C). High temperatures may cause volatilization of organosilicon components and emulsion delamination, affecting defoaming performance; low temperatures (below 0°C) may cause the product to solidify or thicken. After thawing, fully stir and check whether it returns to a uniform emulsion state; if delamination or precipitation occurs, it cannot be used.
Sealing and Shelf Life
- Unopened products: Ensure the packaging barrel is tightly sealed to prevent external moisture and impurities from entering and contaminating the product, and avoid concentration changes caused by solvent volatilization.
- Opened products: If not used up at one time, immediately tighten the barrel lid for sealing to reduce contact with air, prevent the product from absorbing moisture, oxidizing, or mixing with impurities. It is recommended to use up the product within 1–2 months after opening to avoid performance degradation.
Under the above storage conditions, the product shelf life is usually 12–24 months (specifically subject to the product label). After expiration, re-test indicators such as defoaming performance and compatibility, and use the product only if it is confirmed to be qualified.
