In many industrial production processes, strong-alkali environments are common process conditions, for example in cleaning, textile pretreatment, and certain chemical synthesis stages. However, high-concentration alkali solutions very easily cause foam to be generated in large amounts and for a long time. This foam not only reduces the effective volume of equipment and slows down production speed, but may also cause material overflow and uneven product quality, and even affect subsequent process steps, becoming a prominent pain point restricting production efficiency and stability.
Defoamers commonly found on the market often face severe challenges in strong-alkali environments (such as sodium hydroxide solutions): poor stability, quickly saponified or decomposed by the alkali solution, leading to rapid decay of defoaming performance; and short foam-suppression time, requiring frequent addition, which both increases costs and creates an operational burden. Therefore, the industry urgently needs a dedicated defoamer that can truly withstand strong alkali, remain effective durably, and not affect the properties of the system itself.
In response to this core need, leveraging in-depth surface chemistry research, Chemi Tech has developed a series of high-performance strong-alkali-resistant defoamers. Our solution is based on a unique molecular structure design, whose active ingredients remain highly stable under strong-alkali conditions and are not easily destroyed, thereby ensuring the durability of defoaming and foam-suppression performance. The product has the dual effects of fast foam breaking and long-lasting foam suppression, and has good compatibility with strong-alkali systems, without causing secondary problems such as precipitation or oil floating.
The specific application solution is divided into three clear steps: the first step is precise product selection, recommending the best-matching model from the Chemi Tech product line according to the customer's specific alkali concentration, temperature, and foaming system composition; the second step is determining the dosing point and dosage, usually recommended to be added at key points of the process before foam occurs or in its early stage, with the economically efficient initial dosing ratio determined through experiments; the third step is continuous tracking and optimization, in which our technical team helps customers monitor the application effect and fine-tune the dosage according to actual production fluctuations to achieve the best cost-effectiveness.
We once served a company specializing in precision parts cleaning, whose cleaning tank used high-concentration hot alkali solution, and the foam overflow problem had long troubled production. When general-purpose defoamers were used, the effect lasted only a very short time. After adopting the strong-alkali-resistant defoamer customized by Chemi Tech, the foam quickly subsided after dosing and was effectively suppressed throughout the subsequent continuous 8-hour production cycle. The liquid level in the cleaning tank remained stable, avoiding material waste and shutdown cleaning, and the customer fully recognized the product's sustained and stable performance.
Choosing Chemi Tech's strong-alkali-resistant defoamer means choosing a reliable production guarantee. We are committed to helping customers completely solve foam problems in strong-alkali environments and achieve smooth and efficient production processes through professional products and technical services.
