Wynspread SW - 277 소방 폼을위한 슈퍼 웨팅

짧은 설명 :

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.

제품 세부 사항

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.

차세대 AFFF 솔루션은 실리콘 계면 활성제에 의존합니다

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.

실리콘 계면 활성제는 수성 표면 장력을 극적으로 감소시켜 내구성이 확장 된 우수한 확산 및 안정적인 폼을 초래할 수 있습니다.

주요 기능과 이점

• 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.
