Technical field
The present invention relates to water binding agent composition and application, be specifically related to a kind of preparation and application of natural polymer water binding agent of fire-fighting fire extinguishing cooling usefulness.
Background technology
At present, when put out a fire to save life and property large oil tank fire and all kinds of petroleum chemicals storage tanks etc., be common water for fire-fighting purpose facing to the employed refrigerant that cools of cupping jar body and adjacent tank body thereof, this cooling water accounts for more than 90% of delivery of water amount.But the nonwetting characteristic of water and tank surface makes water stop the long period at tank surface, causes 90% above water for fire-fighting purpose to fail to play cooling effect and run off.Therefore, the big scene of a fire need consume a large amount of water for fire-fighting purposes, not only causes the water supply difficulty of water for fire-fighting purpose, easily produces Loss of Water Damage and environmental pollution again.In addition, when the forest of putting out a fire to save life and property, prairie fire, utilize common water for fire-fighting purpose to be injected on leaf and the thick grass, water can drip by the very fast formation globule, be difficult to form effective fire-blocking belt, need to continue water spray and intercept spreading of the intensity of a fire, greatly reduce fire attack efficient and cause a large amount of wastes of water for fire-fighting purpose.
Summary of the invention
One of the problem to be solved in the present invention is, improves cooling water inefficiency, the huge water for fire-fighting purpose system of water loss in the fire attack such as present oil tank, and preparation integrates good wettability, adhesivity and mobile novel water holding refrigerant; Improve the sticking power of fire-fighting cooling water, improve the fire extinguishing cooling efficiency and the suitability of water for fire-fighting purpose, reduce Loss of Water Damage and environmental pollution;
Two of the problem to be solved in the present invention is, forms the water holding fire-fighting medium aqueous solution, can form the fire prevention fire extinguishing isolation strip on forest, grassland after the sprinkling fast, reaches the purpose of quick controlling fires;
Three of the problem to be solved in the present invention is, forms the free of contamination water holding water-repellent agent aqueous solution, is sprayed on the farm crop, is used for keeping crop seedling from drought.
It is main additive preparation water binding agent that the approach that addresses this problem adopts a kind of natural polymer inorganic materials exactly, by the addition of control surface promoting agent, the concentration of natural polymer inorganic materials and the wettability and the adhesivity of particle size adjustment water binding agent, can fundamentally improve the wettability and the adhesivity of fire-fighting cooling water, and keep good flowability, improve cooling efficiency; Utilize the flame restraining effect of inhibitor, strengthen the fire extinguishing and the fiery ability of control of water binding agent by the concentration of adjusting natural polymer inorganic materials and inhibitor; Utilize the synergistic effect of surging of inhibitor, improve the water holding and the water-retaining capacity of water binding agent by the concentration of regulating natural polymer inorganic materials and inhibitor.
Natural polymer water binding agent of the present invention comprises: this water binding agent comprises: component A and B component, perhaps component A and component C; Wherein, component A, this component contains a kind of technical grade natural polymer inorganic materials; B component, this component contains a kind of tensio-active agent at least; Component C, this component contains a kind of inhibitor at least.According to application component A is mixed with water with C with B or component A during use, and the addition by adjusting component A, B, C respectively is to satisfy practical requirement.This water binding agent that the present invention relates to, component A combine the aqueous solution that forms, the cooling when being used for ultra-large type oil tank, all kinds of petroleum chemicals storage tank and petrochemical iy produced tower fire with B; Component A combines the aqueous solution that forms with component C, be sprayed onto and form pollution-free water holding rete, effectively prevention and control forest, prairie fire on forest tree crown and the thick grass; The different concns of component A and component C cooperates, and is sprayed onto on the farm crop, and formation can absorb the pollution-free water binding agent film that water in air is divided, and is used for keeping crop seedling from drought.
Natural polymer water binding agent of the present invention, major ingredient is selected from a kind of sodium alginate, and particle diameter is 70～200 orders.
Natural polymer water binding agent of the present invention, tensio-active agent are selected from least a in the ionogenic surfactant: sodium lauryl sulphate, Sodium dodecylbenzene sulfonate, cetyl trimethylammonium bromide etc.
Natural polymer water binding agent of the present invention, inhibitor are selected from least a in the following material: urea, sodium bicarbonate, primary ammonium phosphate, Secondary ammonium phosphate etc.
Natural polymer water binding agent of the present invention, the cooling when being used for ultra-large type oil tank, all kinds of petroleum chemicals storage tank and petrochemical iy produced tower fire, the addition of component A is 0.05%～0.3% quality branch; (quality branch herein is meant the massfraction of A in whole mixture, down together); The addition of B component is 0.01～0.1mmol/L.(B component is unit with mmol/L, adds with reference to the volume of the water binding agent aqueous solution).
Natural polymer water binding agent of the present invention is used for prevention and control forest, prairie fire, and the addition of component A is 0.2%～0.6% quality branch; The addition of component C is 2～5% quality branches.
Natural polymer water binding agent of the present invention is used for the farm crop keeping crop seedling from drought, and the addition of component A is 0.3%～0.5% quality branch; The addition of component C is 0.03～0.08% quality branch.
Natural polymer water binding agent of the present invention, the jet apparatus when using are selected from least a with in the lower device: straight stream nozzle, water cannon, multi-jet squirt, water fog nozzle, the water fog nozzle etc. of blooming.
Natural polymer water binding agent of the present invention mixes component A with C with B or component A according to application during use with water, and the addition by adjusting component A, B, C respectively is to satisfy practical requirement.Cooling when being mainly used in ultra-large type oil tank, all kinds of petroleum chemicals storage tank and petrochemical iy produced tower fire, the keeping crop seedling from drought on also can be used for putting out a fire to save life and property forest, prairie fire and the agricultural.
