Core advantages and industry innovation of silicone defoamer
-- Enabling technology to solve the problem of industrial bubbles




introduction
Foam problems not only reduce production efficiency, but also may lead to equipment failure and safety risks. Silicone defoamer, with its excellent defoamer performance and wide applicability, has become a key help for industrial upgrading. This paper will deeply analyze its technical advantages, and combined with practical cases to show its innovative significance for industry production.


First, the six core advantages of silicone defoamer
Ultra-low surface tension


Scientific principle: The surface tension of silicone compounds (about 20-24 mN/m) is much lower than that of water (72 mN/m), which can rapidly destroy the structure of foam film.


Empirical data: In paper pulping, the foam volume is reduced by more than 90% after the addition of emulsion defoamer.


High efficiency thermal stability


Tolerance range: Stable performance from -50℃ to 150℃, suitable for high temperature distillation, petrochemical cracking and other scenarios39.


Case: In asphalt processing, silicone oil defoamer can still effectively control foam at 200℃ high temperature to ensure continuous production8.


Chemical inertness and safety


Compatibility: Acid, alkali, salt corrosion resistance, does not interact with the reaction system components, to ensure stable product quality 59.


Environmental certification: The food grade products launched by Sister Technology and other companies have passed ISO 9001 and REACH certification 9.


Small amount, low cost


Economy: Only one part per million (ppm) level of addition can be effective, compared to traditional defoamer cost savings of 30%-50%59.


Anti-foam and anti-foam dual effect


Technical breakthrough: Polyether modified products extend the process stability through the dual mechanism of inhibiting foam formation and rapid foaming.


Environmentally friendly


Biodegradation: The new silicone oil molecular chain can be broken down by microorganisms, reducing the pressure of industrial wastewater treatment 9.


Two, industry innovation cases
Textile printing and dyeing: from "frequent defects" to "zero defects"


Challenges: In traditional processes, foam results in uneven dyeing and rework rates of up to 15%.


Solution: Self-emulsifying defoamer is introduced to realize real-time control of dyeing tank foam, and the qualified rate of finished product is increased to 98%89.


Oil exploration: The Hidden hero of reducing costs and increasing efficiency


Data comparison: In one field, the foam of drilling fluid was reduced by 70% and the bit life was extended by 20%.


Food fermentation: The balance between safety and efficiency


Application: In soy sauce fermentation, the amount of food-grade defoaming agent is only 0.03 g/kg, the fermentation period is shortened by 10%, and the retention rate of flavor substances is increased by 69.


Third, market prospects and strategic cooperation
According to industry forecasts, the global silicone defoamer market will exceed $5 billion in 2025, with a compound annual growth rate of 6.2%. Domestic enterprises such as Sister Technology are developing new products resistant to extreme environments through "industry-university-research" cooperation, and expanding applications in emerging fields such as new energy battery slurry and 3D printing materials.9


Conclusion
The technological progress of silicone defoamer is not only a milestone in the chemical industry, but also an important thrust for the global green manufacturing transformation. In the future, with the growth of demand for customization, this field will continue to lead the dual change of industrial efficiency and environmental protection.
