Abstract
Waterglass (sodium silicate) being used for fire prevention fire extinguishings such as forest and grassland as extinguishing chemical is a new method.This material has a series of excellent properties that help forest and grassland fire extinguishing, and it has certain viscosity, is sprayed on the forest (or grass), promptly be bonded at its surface, be not afraid of wind, under the fire baking, become fire-retardant solid matter overcoat gradually, it is a kind of incombustible inorganic substances, can not only prevent spreading of fire, and energy air-isolation, at high temperature this material foaming, the separation layer thickening, the fire extinguishing effect increases.The waterglass price is low, is easy to store and transportation.This material can spray with general or special apparatus, and suits to use airplane spray, carries out large tracts of land fire prevention, fire extinguishing.
Description
The invention belongs to the fire prevention field.
Forest and grassland are the important component parts of ecological environment, be the wealth of country, and fire damage for forest and grassland.Not only economic loss is big, and will destroy the ecological balance.Though the extinguishing chemical kind of using is many at present, be used for forest (or grassland) fire extinguishing, because the particularity of environment and the influence of wind, effect is very little, and the price height of extinguishing chemical.At present the extinguishing method that adopts of forest (or grassland) generally has: swat, suppression firing, isolation strip method, wind-force fire extinguishing etc.Wind fire-extinguisher fire extinguishing effect is better, but it is just relatively more difficult to put out large-area treetop fire; Suppression firing and manufacturing isolation strip will be paid than higher cost.In order to be applicable to the special environment condition of forest and grassland fireproofing, fire extinguishing, waterglass is used for forest as extinguishing chemical and grassland fireproofing, fire extinguishing still are a new method.
Main chemical is Na
2OmSiO
2NH
2The moisture sodium metasilicate of O, trade name are called for short waterglass sodium silicate, and it is at industrial existing application widely, (as waterglass sand, manufacturing carton etc.).Why waterglass can be used for fire prevention such as forest and grassland, fire extinguishing, is because this material has a series of excellent properties that help grass, wood fire extinguishing.Waterglass has certain viscosity, be sprayed at tree bar, branch, leaf (or grass) when going up (thickness is general more than 0.3 millimeter), promptly be bonded in its surface, be not afraid of wind, under the fire baking, it is retrogradation gradually, be frozen into solid-state overcoat, it is a kind of incombustible inorganic substances, can not only prevent spreading of fire, and the solid separation layer that forms energy secluding air, have the fire extinguishing effect; When the solid water glass layer was added to more than 90 ℃, this material began foaming, makes the separation layer thickening, and tighter; At high temperature also can be burnt till the trickling of molten material, increased the isolation of combustible and air, increased the fire extinguishing effect.
Forest and grassland extinguishing chemical-waterglass are easy to store and transportation; Make abundant raw material, price is low.
When waterglass was used for forest and grassland fire extinguishing, one well matched 20～40% water dilution was beneficial to sprinkling, also can directly use.This extinguishing chemical can be used for general spraying device and spray; Spray better effects if with special equipment; And suit to use airplane spray, carry out the large tracts of land fire extinguishing, as put out treetop fire and grassland big fire.
Claims (1)
- The invention belongs to the fire prevention field.As forest and grassland fireproofing, extinguishing chemical, its main chemical compositions is Na with waterglass 2OmSiO 2NH 2The moisture sodium metasilicate (trade name is sodium silicate) of O.Fire extinguishing feature of the present invention is: water glass solution spray wine is on the forest (or grass) of needs fire extinguishing, promptly be bonded at its surface, under the fire baking, become fire-retardant solid-state inorganic substances separation layer by liquid state, to more than 90 ℃, begun foaming, the separation layer thickening by roasting, at high temperature can dissolve trickling, it is fine and close that separation layer becomes.
