In many industrial production processes involving strong acids (such as sulfuric, hydrochloric and nitric acid), abnormal foam formation often brings a series of troublesome problems. Such foam not only reduces the effective volume of reactors and storage tanks and lowers production efficiency, but may also overflow equipment, causing raw material waste, an environmental cleanup burden and even risks of corroding surrounding areas and affecting operator safety. Especially in strongly acidic systems with high temperature, high shear or surface-active substances, traditional defoamers tend to deactivate and decompose and cannot perform effectively for long, becoming a prominent pain point in production processes.
In response to this urgent market need, Chemi Tech's R&D team has launched a specially designed series of strong-acid-resistant defoamers. The core advantage of this series lies in its outstanding chemical stability. They adopt a specially modified silicone-polyether composite system and carefully selected inert carriers, enabling them to maintain structural integrity and activity over time in high-concentration acidic environments and resist decomposition or neutralization by strong acids, thereby achieving durable, highly efficient defoaming and foam-inhibiting performance.
Our solution is clear and definite, divided into four steps: Step 1, detailed assessment. Our technical engineers deeply understand the customer's acid type, concentration, temperature, process and foaming substances. Step 2, targeted recommendation. Based on the assessment results, we select the most suitable grade from Chemi Tech's strong-acid-resistant product matrix, possibly involving products with different viscosity, dosage and dispersion characteristics. Step 3, on-site test verification. We provide samples for small-scale or pilot trials under the customer's actual working conditions to precisely verify defoaming speed, foam-inhibiting durability and possible effects on the system. Step 4, providing a stable product supply and follow-up process optimization suggestions to ensure the reliability of long-term operation.
For example, a company in East China producing specialty chemicals, in a key synthesis step using concentrated sulfuric acid, generated a large amount of stubborn foam due to side reactions, which limited feed amounts, prolonged the reaction cycle and posed safety concerns. After adopting the specific strong-acid-resistant defoamer recommended by Chemi Tech, the foam was controlled rapidly, reactor utilization increased by about 20%, single-batch production time was shortened, and the risk of acid splashing was avoided, making the production process smoother.
Chemi Tech strong-acid-resistant defoamers are suitable for strongly acidic environments in many fields, including pickling, metal surface treatment, chemical synthesis and ion exchange resin regeneration. Through professional products and technical service, we are committed to helping customers overcome foam obstacles and improve process efficiency and production safety.
