Description

Механизм действи  пены при ненотушении гор щих жидкостей, например нсфтеиродуктов, состоит в том, что когда на зеркало гор щей жидкости подают пепу, пена растекаетс  и образует слой, преп тствующий передаче тепла от факела пламени к жидкости и выходу паров жидкости , в результате чего плам  гаснет, так как гор т не собственно жидкости , а их пары.The mechanism of action of the foam when non-extinguishing burning liquids, such as naphtha products, is that when ashes are placed on the mirror of the burning liquid, the foam spreads and forms a layer that prevents heat transfer from the flame to the liquid and the vapor of the liquid, resulting in a flame extinguishes, because hot gases are not actually liquid, but their vapors

Существенным недостатком, свойственным огнегас щим пенам,  вл етс  адсорбци  паров гор чей жидкости пленками, образующими пузыоькн пепы.A significant disadvantage of the fire extinguishing foams is the adsorption of hot liquid vapors by films forming bubble ashes.

Пары горючего, скопившиес  на границе раздела пенагорюча  укидкость, вследствие снижени  устойчивости иенного покрова за счет адсорбции, начинают про1и-1кать впутрь пузырьков, что приводит к прорыву сло  пеиы и потере ее изолирующего действи .Fuel vapors accumulated at the boundary of the penhill gas dip, due to a decrease in the stability of the woolen cover due to adsorption, begin to penetrate into the air of the bubbles, which leads to a breakthrough of the layer of insulin.

Поэтому сн11же1 ие способности адсорбции паров гор щей ж:;т:-;;:сти пузь рькал1и огисгас щей иеиы представл ет значительный ческий интерес.Therefore, lowering the ability of adsorption of burning vapors::; t: - ;;: to the discharge of the extinguishing ion is of considerable interest.

Предложен новый способ тушени  легковосиламен ющихс  ropio уих жидкостей с применением пен, заключаюц1,ийс  в том, что, с цельс снижени  способности адсорбции паров горючего пенным покровом, в состав пенообразующей композиции ввод т высокомолекул рное вещество , например поливиниловый спирт.A new method has been proposed for extinguishing highly ropio-sensitive fluids using foams, concluded that, in order to reduce the ability of fuel vapor adsorption to foam, a high molecular weight substance such as polyvinyl alcohol is introduced into the foaming composition.
