Product Details
1. Basic Information
- Product Name: Defoamer
- Brand Model: DF - 114
- Packaging Specification: 20 kg/barrel
- Main Ingredient: Polyether (a linear polymer compound polymerized from raw materials such as ethylene oxide and propylene oxide)
2. Product Characteristics
(1) Physical Properties
- Appearance: Colorless to light yellow transparent liquid with good fluidity, facilitating rapid dispersion in production.
- Density: 0.9 - 1.1 g/cm³, with good compatibility with water and most solvents.
- Flash Point: 60°C. It should be kept away from fire sources and high - temperature environments during storage and use.
- Temperature Resistance: Can withstand a high temperature of 130°C and maintain stable defoaming performance in high - temperature processes.
(2) Core Performance
- High - Temperature Adaptability: Specially designed for high - temperature printing and dyeing scenarios. It can effectively eliminate foam generated by high - temperature steam and auxiliary agent stirring in dyeing, rinsing and other processes below 130°C, avoiding problems such as color spots and dyeing spots caused by foam.
- Low Impact on Transparency: When used in cleaning agents, it will not damage the transparency of the system, and is suitable for detergent, glass cleaner and other products with appearance requirements to ensure that the finished product is clear and transparent.
- Broad Applicability: In addition to high - temperature printing and dyeing, it can also be used in daily chemical products (such as shampoo, body wash) to inhibit process obstacles caused by surfactant foaming during production and improve product stability.
3. Action Principle
Polyether molecules achieve defoaming and foam inhibition through the following mechanisms:
- Rapid Bubble Breaking: It quickly penetrates into the foam liquid film at high temperatures, reduces the surface tension, and makes the foam film wall thin and break.
- Long - Lasting Foam Inhibition: It forms a dynamic protective film in the system to prevent bubbles from aggregating and inhibit the formation of new foam, especially in high - temperature cycle processes.
- Stable Compatibility: The molecular structure is resistant to acids, alkalis and electrolytes, and is not easy to react with printing and dyeing auxiliaries and daily chemical raw materials, ensuring process stability.
4. Applicable Scenarios
(1) High - Temperature Printing and Dyeing Field
- Dyeing Process: When disperse dyes and reactive dyes are dyed at high temperatures, eliminate foam generated by dye dissolution and stirring of high - temperature and high - pressure equipment to ensure dyeing uniformity.
- Post - Treatment Process: Control foam during rinsing and soaping to avoid foam residue affecting the hand feel and color brightness of the fabric.
(2) Cleaning Agent Production
- Glass Cleaner: After adding, it does not affect the transparency of the solution, effectively eliminates foam generated by spraying or stirring, and improves cleaning effect and user experience.
- Industrial Cleaner: When used for metal surface cleaning, it inhibits the impact of foam on the efficiency of ultrasonic cleaning and spray cleaning to ensure thorough dirt removal.
(3) Daily Chemical Field
- Washing and Care Products: In the production of shampoo and body wash, control the foaming amount of surfactants to facilitate filling and use, without affecting the consistency and foam fineness of the product.
- Detergent: Added to laundry detergent and dishwashing liquid to reduce foam overflow during transportation and use, and improve product packaging and use safety.
5. Usage Methods and Precautions
(1) Usage Methods
- Addition Amount: Generally 0.05% - 0.2% of the total system volume. In high - temperature printing and dyeing scenarios, it can be appropriately increased to 0.3%. The specific dosage needs to be determined by small sample tests according to the severity of foam.
- Adding Method: It can be added directly or diluted 5 - 10 times with warm water and then added dropwise. In high - temperature processes, it is recommended to add continuously at the equipment feed port or in the circulation pipeline to ensure uniform dispersion of the defoamer.
(2) Precautions
- Storage Conditions: Store in a cool and ventilated place, avoid direct sunlight, store at a temperature of 5 - 35°C, and keep away from fire sources (low flash point).
- Safety Protection: Wear gloves and goggles during operation. If it comes into contact with the skin, rinse with clean water. Avoid ingestion or contact with eyes.
- Compatibility Test: Before using with a new system, a compatibility test must be carried out first to ensure that it does not affect the transparency or performance of the product (especially in cleaning agents).
