Foam Products Foam Extinguishing rolled paper art Systems (FOAM): Foam is a chemical compound. Pressure when mixed with water, the mixture of foaming and foam mixed with air passing through the compressed form. Foam; fire completely covers the surface like a blanket, cut contact with air, the cooling rolled paper art property has. It is therefore a good extinguisher.
* Chemical Foam with aluminum sulfate [Al2 (S04) 3 - l8 H2 o] with sodium bicarbonate (NaHCO3), "You're in koh" in the presence of a substance is dissolved in water at the end of the resulting foam. Is hardly used nowadays. * Protein-based foams, protein-based foams by chemical hydrolysis of animal and vegetable waste is obtained. rolled paper art There are two types. * Regular protein-based foam; pure hydrolyzed protein. Foam stabilizers, rolled paper art freezing point depressants have occurred and preservative. Hydrocarbon fire extinguisher is good for. * Fluoro Protein Based Foam; Regular fluorocarbon compounds in addition to protein-based foam provides fluid.
Regular protein foam can summarize the rule. Fire is under control more quickly. Is more fluid. Covering ability is high. Back prevents ignition. Property deteriorate rolled paper art when mixed with dry chemical powder. The fuel tank has the ability to be at the bottom. Regular fluid mixed into a protein-based foam.
* Synthetic foam, synthetic detergent composition is the ability to foam and quickly. In this respect, medium and large size are used in order to obtain the foam. In general, if used with foam generator foam 100-1000 times gives the possibility to obtain. With the type of fire, in the hangar for aircraft fire extinguisher is to be preferred. * Alcohol rolled paper art resistant foam (ATC): Regular protein foam liquid metal soap (organo metal esters) is obtained by adding foam. Such a foam material, especially polar solvents, alcohol type well in the fire extinguisher of the plaster is able to shine, since the water insoluble hydrocarbon may be quenched with a normal foam material. However, if polar solvents (alcohols, ethers, ketones) is dissolved in water again mixed with water in the foam blanket ignites. rolled paper art So to do this type of chemical fires (ATC) Alcohol-resistant foam type should be used. * AFFF (Aqueous Film Forming Foam) with fluoro-carbon compound is a combination of synthetic foam liquid fire extinguishing very abrupt. Hydrocarbon suds reducing the surface tension of the film to help spread the sudden isolation, the effect continues for a long time. Back to definitely prevent ignition.
Search foams in general specifications: * foam in liquid form must be hydrolyzed, * Foaming agent with the water mixture should be from 2% to 10%. * Pressure water mixture resulting foam, high heat-degradable, wind dispersal should, dry chemical powder should not be affected, * Foam material (PH) value (acid value) from 7 to 8.8 should be * when mixed with water, for at least 15 times the foam should be set * must be at least 10 years of losing property. * Usually between rolled paper art -10 Co. 50 Co. should not precipitate.
* Refineries, chemical laboratories, chemical tanks, * Paint and varnish workshops or warehouses, * Fuel storage areas and filling stations * No more oil spills ditches, * Fuel tanks, tankers, rolled paper art cargo holds, * Airports, aircraft hangars, as similar places counted. Use foam to be used in the field can şemalaştır foam types are as follows
* LPG fire extinguisher is not suitable for. * Heavy oils should not be processed. * Electric current passes, breakers rolled paper art should not be processed while. * Food items should not be processed on. Qualities of food items is broken.
* Search for processing of the canister with tap; Pumper 100 with a hose connected to the fire scene near the point, and then tap Search, stands on intermediate tap of the rotator 85 is connected rolled paper art with participation record. Search the foam canister hose faucet outlet end of the hose is connected to the 85. Water absorption of the foam from the canister pressure causes arrive. Adding foam to the nozzle lance is made fire processing. This method is used for small fires.
* Sprinkler Foam from the Procedure: For this purpose, a pumper in the foam tank is located next to the cistern. Such as water works opened fire hose is connected to the vehicle. Water and foam valve opens, inserted at the end of the hose to the fire lances are processed. Water lance pass pressurized air from the air passage to be sucked up. So lots of foam is formed.
* With Foam Generator Foam Processing: With record participation by 110 foam generator is connected to. The pressure of water of the generator to rotate the impeller, thereby capable of expansion abundant foam breathable. In particular, synthetic foams that greatly increase the volume of fuel tank foam handle fires with foam generator is onsite.
* Foam Application Rate: Foam A, B, C class fires applied. Apply
