Low expansion foam

Foaming ratio equal to or less than 20 times the bubble

Features

A protein foam produced 8 times expansion degree, such as FLUOR-FOAMOUSSE

A synthetic foam produced 20 times, such as MOUSSOL-APS F-15.

By many small bubbles composed of small volume, relatively heavy "wet" bubble. Low expansion foam fluidity, fire retardant, good air tightness, can effectively resist again.

According to the different types of foam liquid and the mixing ratio of different times, the surface low foam can good adhesion on vertical objects. The main source of foam fire extinguishing function to adhere well to the vertical surface, the fire is mainly based on the isolation and cooling effect. If the AFFF fire extinguishing, is based on the characteristics of the film.

Low expansion foam production in low expansion foam pipe, fire gun times and mobile or fixed foam device. To baffle or dirty in the stacking area, installation such as drainage elbow device, can produce better than air bubble expansion. Bubble finer more stable foam is produced.

Application field

Due to the low liquidity bubble times outstanding, it can be used to put out the fire can be extinguished liquid, solid fire. The foam covering the surface of the combustion in the shortest time and form a good airtight layer, put out the fire.

For solid fire, low foam good viscosity even make the vertical attached on the surface of the object, so as to enhance the fire extinguishing effect.

Special foam process, such as "compressed air foam system" can achieve the effect. As a means of prevention, the use of low expansion foam can inhibit combustible gases. Airtight, isolated, foam layer can cool the surface of combustible material covered in long time.Because the foam is relatively heavy, low foam can spray distance, which makes the firefighters can fire at a safe distance. Aqueous film-forming foam concentrate, such as STHAMEX AFFF, MOUSSOL APS, SCHAUMGEIST FFFP can be in the form of aqueous solution for expansion foam and foam without suction. For example, at the airport, oil depot, plastic industry, ship and land and sea. The foam concentrate can be used for automatic fire extinguishing device and jet equipment for fire extinguishing. The analysis of water bubble rate is very high, is conducive to the formation of water film and enhanced foam fluidity.

In times of bubble

21 to 200 times the foamability of foam

Features

According to the bubble generation rate is composed of fine bubble foam, or "wet" by "dry" bubble bubble, small weight and volume is large. The fire extinguishing effect is mainly based on the isolation, and the inhibitory effect of cooling. In times of foam production in foam branch. Foam solution stirring and mixing the air inhaled in foam branch pipes, and hit the inside of the branch pipe wire, foam expansion occurs. In this way can produce large amounts of high foam can be piled up in a short period of time.

Application field

Thanks to its wide range of foaming, the scope of application in foam is also very wide: 50-100 times the rate of foam can be used for plastic foam, tire, and liquid fire, can also be used to extinguish the fire. 100-200 times the rate of foam foam can be used in submerged flat space, for example, mine shaft channel and any need to succeed the rapid production of large amounts of foam extinguishing. In times of foam spraying range is about 12M, so the supply of relatively mild foam. The bubble can flow rapidly from surface in the fire, and the foam layer to form a closed, gas tight. When the polarity of the solution of fire, the use of ethanol aqueous film MOUSSOL-APS foam concentrate can effectively extinguish fire. In the design of double bubble generator used in industrial fields of fire extinguishing, concentrated liquid ratio is about 1:25 to 1:35, but the jet range is about 35 meters.

High foam

Foaming ratio greater than 200 times of foam

Features

For example, artificial foam concentrate SthamexF-15, requires only a small amount of water and foam concentrate can produce foaming multiples more than 200 times the bubble. The foam volume is large, light weight. High foam containing air proportion is large, so it is a big bubble formed by the "dry" bubble. Because of its large volume, light weight, high foam injection can not be so. Mainly depends on its effect in the separation, insulation and fire suppression effect. This suppression effect is due to the high expansion foam relatively high rate of deterioration, effects of a bubble in the water after precipitation by high temperature fire direct evaporation, the formation of a large number of water vapor over the fire. The air around the fire by dilution and cooling. High foam in high expansion foaming builder.

Application field

In the limited space area, high foam can maximize the extinguishing effect. Thanks to the high foam expansion rate high, even in such a large area of the hangar or warehouse class can quickly fill in a short period of time. With the appropriate size of the aqueduct high foam will be imported from the internal and external protection objects, or by ultra high temperature combustion gas bubble generator used in the production of foam. The water content in the foam is relatively low, so it can avoid a large area of water. As a defensive measure, high foam can inhibit the combustible gas and can provide effective protection against heat and combustible gas.

Inside Air Foam System - closed space expansion foam system

Inside Air Foam (IAF) is in the high foam production system using closed space. For example, in a warehouse fire ship engine room. For the production of foam, 1000 degrees up to the release of IAF in the use of fire temperature containing combustible gas soot. Ultra high foam concentrate and such and system and high-temperature combustible gas use.
