Description
Technical field
The invention belongs to stacking extinguish material technical field, being specifically related to a kind of extinguishing chemical for putting out cotton spinning stacking fire.
Background technology
The main component of wollen fabrics is cellulose, lignin, the combustible materials such as wax and fat, and cotton fiber is little and fluffy, large with air contact surfaces, run into tiny Mars and can cause burning, cotton burning velocity is 16-25 times of combustion of wood speed, after catching fire, moment just can expand in flakes, after cotton spinning stacking is on fire, the intensity of a fire is from stacking surface to vertical-depth, from stacking lower to upper part, from a stacking to the many-sides such as another stacking interior extension burning in length and breadth, and wollen fabrics quality is loosened, under the effect of strong wind or scene of a fire thermal current, stacking combustion debris and burning fibres group throw in the air, descend slowly and lightly on other stacking or combustible, very easily cause many places on fire.
Simultaneously, stacking skin catches fire and easily causes its inside to be glowed, the high temperature in the scene of a fire, and the higher stacking of some local temperatures can be made to glow on fire, burning area is caused to expand, put out its outside fight be not equal to put out whole stacking fire, add cotton and there is drainage, once water impact stacking, fine and close interlayer by current compress tighter, cause water not enter inside stacking, make the smoldering fire inside stacking can not get putting out, easily revivable phenomenon occurs.
Extinguishing chemical common at present has water, foam, alkyl halide, carbon dioxide etc., and the gas extinguishing agent prices such as alkyl halide, carbon dioxide, inert gas are higher, and are difficult to give play to its fire-fighting efficiency when large area uses; Powder extinguishing agent fire-fighting efficiency is higher, and blow-off velocity is fast. but effect that is little to the cooling effect of burning during dry-chemical fire extinguishing, that substantially do not possess the evaporation that covers and prevent to burn, and glowed in stacking inside and substantially do not play a role; It is high that fire foam is applied to combustible liquid fire fire-fighting efficiency, and blow-off velocity is fast. but be used for putting out a fire to save life and property that cotton spinning stacking fire usefulness is low, consumption is large, uneconomical.Therefore seek a kind ofly effectively to put out cotton spinning stacking fire, effectively avoid the extinguishing chemical that stacking combustion debris is dispersed and glowed to be possess very important meaning to those skilled in the art.
Summary of the invention
For solving the problems of the technologies described above, there is provided a kind of extinguishing property good, can effectively avoid stacking burn diffusion and glow, the high-performance extinguishing chemical that simple and easy to get, production cost is low, the invention provides a kind of extinguishing chemical that efficiently can put out cotton spinning stacking fire, it consists of the following composition by weight:
In the above-mentioned extinguishing chemical for putting out cotton spinning stacking, described cellulose derivative is cellulose esters analog derivative, be preferably in cellulose nitrate, cellulose ethanoate, cellulose acetate butyrate and cellulose xanthate any one or multiple, more preferably cellulose nitrate.
In the above-mentioned extinguishing chemical for putting out cotton spinning stacking, described stabilizing agent be selected from ethylene glycol, 1,3-PD, glycerine, chlorinated paraffin wax any one or multiple, be preferably glycerine.
In the above-mentioned extinguishing chemical for putting out cotton spinning stacking, described each composition by weight is preferably:
The preparation method of the above-mentioned extinguishing chemical for putting out cotton spinning stacking is as follows: by mass fraction, cellulose derivative, polyethylene glycol, APP, proline, stabilizing agent successively water-soluble rear preparation are become concentrate, adopt 3-10 times of water dilution during use, obtain final fire extinguishing solutions.
Compared with prior art, there is following advantage in the extinguishing chemical for putting out cotton spinning stacking provided by the invention:
1, the extinguishing chemical for putting out cotton spinning stacking provided by the invention can put out rapidly cotton spinning stacking surface naked light flame, and effectively stops stacking comburant to disperse;
2, the extinguishing chemical for putting out cotton spinning stacking provided by the invention effectively can infiltrate cotton spinning stacking inside, effectively stops stacking inside to be glowed;
3, do not comprise any halogen for the extinguishing chemical putting out cotton spinning stacking in the present invention, security and the feature of environmental protection improve greatly, and prescription is simple, and preparation technology is simple and easy to get, and production cost is lower, is more suitable for commercial Application.
Present inventor examines the impact of each component proportion selection for cotton spinning stacking extinguishing chemical extinguishing property by great many of experiments, and it is as follows that part realizes result, and concrete evaluation index is see standard GB/T/T 17835-2008.
Test 1 each component proportion to select
By mass fraction, the each component of extinguishing chemical being used for putting out cotton spinning stacking of different ratio successively water-soluble rear preparation is become concentrate, concentrate is carried out extinguishing property test with after 5 times of water dilutions, and wherein each component proportion of extinguishing chemical is in table 1, and its extinguishing property test result is in table 2.
The each component proportion of table 1 extinguishing chemical
The choice experiment result of the different extinguishing chemical of table 4
Can find out according to the above results, when cellulose derivative be 15-40 part, polyethylene glycol is 6-15 part, APP is 6-15 part, proline is 2-6 part, stabilizing agent is 3-8 part, water is 20-68 part time, the extinguishing chemical attack time obtained is short and can not resume combustion, exceed this scope then attack time increase or can resume combustion, wherein when cellulose nitrate be 25 parts, polyethylene glycol is 10 parts, APP is 8 parts, proline is 4 parts, glycerine is 5 parts, water is 48 parts time effect optimum.
