All-weather fire retardant valve principle
The all-weather fire retardant valve is a new type of safety equipment necessary for petrochemical storage tanks. Its great advantage is that it has good fire resistance, light weight and convenient maintenance. It is suitable for Class A oils with a flash point below 28 ° C and Class B oil with a flash point below 60 ° C. Such as gasoline, kerosene, diesel, crude oil, benzene, toluene, ethanol and other medium storage tanks, it works normally in the temperature environment of -35 ° C - +60 ° C. The all-weather fire-resisting valve is used to install the main safety equipment on fixed top tanks such as crude oil, gasoline, kerosene, light diesel oil and aromatics. It is used for evaporation loss and protection of the tank from damage during overpressure or vacuum. It also has the characteristics of large ventilation, good sealing performance, small leakage and corrosion resistance. Operating pressure: |

Surfactants, known as "industrial monosodium glutamate", refer to substances with fixed hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and make the surface tension decrease significantly. Surfactants are generally organic amphoteric molecules with hydrophilic and hydrophobic groups, which are soluble in organic and aqueous solutions. Hydrophilic groups are often polar groups, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amino groups and their salts, but also hydroxyl, amide, ether bonds; hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than eight carbon atoms. Surfactants are classified into anionic surfactants (mainly soaps, sulfates, sulfonates), cationic surfactants (also known as quaternary amines), amphoteric surfactants and non-ionic surfactants (mainly including fatty acid sorbitans, polysorbates, polyoxyethylene fatty acid esters) Polyoxyethylene fatty acid ether, etc.)
