Description
Tørt brannslukningspulver som ikke innvirker ugunstig på skumstabiliteten. Dry fire extinguishing powder that does not adversely affect foam stability.
Som brannslukningsmidler har natri-um- og kaliumbicarbonat vært kjent i lang Sodium and potassium bicarbonate have been known as fire extinguishing agents for a long time
tid som et særlig virksomt middel. Ved tilsetninger av bestemte flyte- og hydrofoberingsmidler får man tørre brannslukningsmidler med gode egenskaper. I de senere time as a particularly effective means. With the addition of specific floaters and hydrophobic agents, dry fire extinguishing agents with good properties are obtained. In the later ones
år har tørre brannslukninkspulvere imid-lertid fått en økt anvendelse, også for years, however, dry fire-extinguishing powders have seen an increased use, also for
mange industriarter og også for brannbe-skyttelse i luftfarten, og som følge herav many types of industry and also for fire protection in aviation, and as a result
stilles det økete krav til egenskapene av increased demands are placed on the properties of
tørre brannslukningsmidler. I henhold her-til kreves anvendbarhet av slike midler og-så ved sådanne branntilfeller hvor det er dry fire extinguishers. In accordance with this, applicability of such means is also required in such cases of fire where there is
hensiktsmessig å anvende en kombinert appropriate to use a combined
slukningsprosess. Dette er fremfor alt til-fellet ved brann i fly, hvor det først ved en quenching process. This is above all the case in the event of a fire in an aircraft, where the first
såkalt «førsteinnsats» for å oppnå en hur-tig nedslåing av flammene anvendes tørre so-called "first step" to achieve a rapid suppression of the flames is used dry
brannslukningsmidler, og i en «anneninn-sats» anvendes et slukkeskum, hvilket i det fire extinguishing agents, and in an "anneninn batch" an extinguishing foam is used, which in it
vesentlige skal tjene til avkjøling og for-hindring av pånyoppblussing av ilden. must serve to cool and prevent the fire from re-igniting.
Herunder har man som bekjent fast-slått at de normale hydrofoberingsmidler Below, as is known, it has been established that the normal hydrophobizing agents
som f. eks. høyere fettsyrer og disses salter, like for example. higher fatty acids and their salts,
samt i liten utstrekning også silikoner, innvirker ugunstig på skumstabiliteten. For and to a small extent also silicones, adversely affect the foam stability. For
like overfor dette å forbedre skumstabiliteten ved anvendelse av bicarbonat-slukkepulvere har man efter et kjent forslag til-satt disse carbonatoppløsninger. I henhold just opposite to this, to improve the foam stability when using bicarbonate extinguishing powders, one has, according to a known proposal, added these carbonate solutions. According
til det tyske Auslegeschrift 1 098 366 inneholder et slikt tørt slukkepulver en blanding av kalsium- og magnesiumcarbonat. to the German Auslegeschrift 1 098 366 such a dry extinguishing powder contains a mixture of calcium and magnesium carbonate.
Overraskende nok ble det nu funnet at Surprisingly, it was now found that
skumforlikligheten (Schaumvertråglich-keit) av bicarbonat-slukkepulveret kan for-høyes i en vesentlig grad når man i steden-f or den ovenfor nevnte jordalkali-carbonat-blanding i hvilken magnesiumcarbonatet og dettes andel i hovedbestanddelene av alkalibicarbonat kan andra inntil 35 vektprosent, er erstattet med magnesiumammoniumfosfat med 6 krystallvann. Som det har vist seg gir hverken magnesiumfosfat alene eller kalsiumcarbonat alene som tilsetning til alkalibicarbonater en skumfor-liklighet resp. en sådan av noen som helst praktisk verdi. Også magnesiumcarbonat er for seg alene ikke av tilstrekkelig •virk-ning. The foam compatibility (Schaumvertråglich-keit) of the bicarbonate extinguishing powder can be increased to a significant extent when, instead of the above-mentioned alkaline earth carbonate mixture in which the magnesium carbonate and its proportion in the main components of the alkali bicarbonate can be up to 35 percent by weight, is replaced with magnesium ammonium phosphate with 6 water of crystals. As has been shown, neither magnesium phosphate alone nor calcium carbonate alone as an addition to alkali bicarbonates gives a foam consistency or one of any practical value. Magnesium carbonate is also not sufficiently effective on its own.
Tørrslukkepulveret som ikke innvirker ugunstig på skumstabiliteten, inneholder til dette formål som skumstabiliserende tilsetning en jordalkalisaltblanding som inneholder 40 til 70 vektprosent kalsiumcarbonat og 30 til 60 vektprosent magne - sium-ammoniumfosfat (MgNH4 . 6 H20), og hvilken blanding kan utgjøre inntil 35 vektprosent av tørrslukkepulverets total-mengde. The dry extinguishing powder, which does not adversely affect the foam stability, contains for this purpose as a foam stabilizing additive an alkaline earth salt mixture containing 40 to 70 percent by weight calcium carbonate and 30 to 60 percent by weight magnesium ammonium phosphate (MgNH4 . 6 H20), and which mixture can make up to 35 percent by weight of the total quantity of the dry extinguishing powder.
I den efterfølgende tabell er til sammenligning vannutskillelsesfaktorene av forskjellige pulverblandinger stillet mot hverandre. (Med vannutskillelsesfaktor «F» skal forståes: forholdet mellom den midlere vannutskillelseshastighet fra skummidlet som sådant alene = «f O» til skummidlet efter tilsetning av tørrpulver = «f».) In the following table, the water separation factors of different powder mixtures are compared to each other. (The water separation factor "F" is to be understood as: the ratio between the average water separation rate from the foaming agent as such alone = "f O" to the foaming agent after the addition of dry powder = "f".)
Skummet utsettes ved dette forsøk for innvirkningen av en definert varmekilde av 538° C og den fra skummet uttrådte vannmengde bestemmes i avhengighet av In this experiment, the foam is exposed to the influence of a defined heat source of 538° C and the amount of water released from the foam is determined depending on
I tiden. Formelen lyder i overensstemmelse In the time. The formula reads in agreement
hermed: hereby:
Av den foran anførte sammenligning fremgår det tydelig den fremragende virkning av en blanding bestående av kalsiumcarbonat og magnesiumammoniumfosfat. From the above comparison, the outstanding effect of a mixture consisting of calcium carbonate and magnesium ammonium phosphate is clearly evident.
Anvendelsen av magnesiumammoniumfosfat i stedenfor som hittil av magnesiumcarbonat medfører dessuten den for-del at fremstillingsprisen er liten, men fremfor alt har magnesiumammoniumfos-fatet til følge en bedre slukke virkning. For-uten tilsetningen av kalsiumcarbonat og magnesiumammoniumfosfat som i henhold til oppfinnelsen er betingende for skumforlikligheten eller for at pulveret ikke innvirker ugunstig på skumstabiliteten, samt na-trium- og/eller kaliumbicarbonat kan et skumforliklig tørt slukkepulver i henhold til oppfinnelsen dessuten inneholde i og for seg kjente tilsetninger av finmalt talkum, glimmer, butadien og lignende. The use of magnesium ammonium phosphate instead of, as hitherto, magnesium carbonate also entails the advantage that the production price is small, but above all, the magnesium ammonium phosphate has a better extinguishing effect. In addition to the addition of calcium carbonate and magnesium ammonium phosphate, which according to the invention is conditional for the foam compatibility or for the powder not to have an adverse effect on the foam stability, as well as sodium and/or potassium bicarbonate, a foam-compatible dry extinguishing powder according to the invention can also contain in and for known additions of finely ground talc, mica, butadiene and the like.
Da tørre slukkepulvere i henhold til oppfinnelsen skal være oppbygget på basis av alkalibicarbonater, så er i overensstemmelse hermed andelene av den i dette til-stedeværende blanding av kalsiumcarbonat og magnesiumammoniumfosfat mindre enn mengden av alkalibicarbonatet eller alkali-bicarbonatene og er som regel fra ca. 5 vektprosent inntil 35 vektprosent av tørr-slukkepulveret. I blandingen av de to i henhold til oppfinnelsen for forbedring av skumf orlikligheten anvendte j ordalkali-salter kan de til enhver tid foreliggende andeler av det ene og det annet salt for-øvrig varieres efter ønske, alt efter de i det foreliggende tilfelle ønskede egenskaper av tørrslukkepulveret. As dry extinguishing powders according to the invention must be built up on the basis of alkali bicarbonates, accordingly the proportions of the present mixture of calcium carbonate and magnesium ammonium phosphate are smaller than the amount of the alkali bicarbonate or alkali bicarbonates and are usually from approx. 5% by weight up to 35% by weight of the dry extinguishing powder. In the mixture of the two alkaline earth salts used in accordance with the invention for improving foamability, the proportions of one and the other salt present at any time can be varied as desired, depending on the desired properties of the dry extinguishing powder.
