Wynspread SW - 277 Superwetting لرغاوي مكافحة الحرائق

WynSpread SW-277 Superwetting for Firefighting Foams

وصف قصير:

There’s serious science behind getting firefighting foams to spread across fuel

It comes down to the spreading coefficient. In simple terms, it’s the difference between the surface tension of the fuel and the interfacial tension between it and the firefighting liquid.

If the spreading coefficient is positive, the firefighting liquid well spread. If it’s not, wetting will not be complete, and the fire can rage on unabated.

تفاصيل المنتج

Historically, drastically reducing surface tension was a job for fluorinated surfactants, such as perfluoroalkyl surfactants (or PFAS), but these solutions have come under scrutiny due to environmental and human health concerns.

تعتمد حلول AFFF من الجيل التالي على السطحي السيليكون

AFFF formulators are now turning their attention to silicone surfactants, more specifically trisiloxane alkoxylates, which have shown exceptional performance in AFFF solutions, as well as spreading applications in the agriculture, coating, paints and textile industries.

يمكن أن تقلل السطح السطحي السيليكون بشكل كبير من التوتر السطحي المائي ، مما يؤدي إلى انتشار ممتازة ورغاوي مستقرة مع متانة ممتدة.

الميزات والفوائد الرئيسية

• Lower surface tension compared to traditional organic surfactants.

• Able to form stable foams that spread across low energy hydrocarbon烃 surfaces, such as fuels

• Formulated without fluorine.
