Description

DETAILED DESCRIPTION OF THE INVENTION The present invention, as set forth in the introductory section of the first claim, is directed to a decontamination solution.

The decontamination agent liquid that is in the air is calcium chloride 7.5
ti/f-), or 15 to 100 calcium chloride,
Emulsifiers 1 to 3 consisting of a mixture of n-alkylbenzosulfonate, alkyl polyglycol ether and a solvent. - consists of

This decontamination emulsion has a thick, milky viscosity through its emulsifier and has a decisive influence on the decontamination action by reducing the flow rate on the sloped surface.

The purely chemical decontamination mechanism of this common emulsifier essentially consists of hydrolysis and oxidation of contaminants by calcium chloride and water. The decontamination agent is favored in the case of hygrophobia toxin through the solubility properties of arm-chloroethylene and by the greatly enlarged surface due to the effectiveness of emulsifiers. additional lens side
s) or the effect of the emulsifier is: - through the essentially stable emulsion in the emulsification of 2-chloroethylene and the associated increase in viscosity, the inhibition of precipitation of higher specific gravity than calcium chloride or calcium hypochlorite; including.

Applying thick, viscous decontamination emulsifiers should not be applied to contaminated surfaces or mechanically streaked surfaces.
The contaminated surface is then covered by an adhesive layer of decontaminating emulsifier several days thick. At the end of the required period of action, the washed-out decontaminant is removed by brushing away with water or by rinsing with forceful water.

For this flooded emulsion, there is no detrimental effect, while the decontaminated emulsion is increased by the emulsifier mentioned,
Rapid flow rates are inhibited, internal mixing of the applied emulsion is lacking, and the chemicals act directly on the boundary layer of contaminated material. Furthermore, outward movement of the boundary layer occurs with the application of relatively large amounts of emulsion, which facilitates decontamination and causes the common viscous emulsion to become entangled in spherical nodules in the contact area of the surface. . It is clear that this process involves high consumption of decontaminant liquid. For example, for the decontamination of large motor vehicles, an estimated decontamination effect of approximately 4QQm/ is estimated.

Furthermore, a disadvantage of the contaminated emulsions appears to be the difficulty of removal from contaminated surfaces associated with their increased viscosity. Calcium hypochlorite and/or calcium chloride, providing water-wicking properties;
water, and/or perchlorethylene, a cleaning active substance having the following composition: (a) 0.1 to 0.1 to 0.1 to 0.1 to 0.1 to 0.5% of nonylphenol polyglycol ether with an ethoxylation value of 12 to 50 EO'i;

1 to 10 parts by weight (in proportion to 100 parts by weight of the complete emulsion), and/or (c) general formula: where R1 and R2 have 1, 2 or 3 carbon atoms. It is an alkyl group, and R6 is a lauryl group.

from 0.1 to 10% by weight of an amine oxide (which is a myristyl, stearyl, decyl, cetyl alkyl, or alkyl group from the average carbon chain distributed in tallow or coconut mal) 10
It has previously been proposed (German patent application P3047919.7) to formulate the decontamination liquid contained with 0 parts by weight).

The task of the present invention is to improve decontamination agents of the type described at the outset, and to achieve this task in such a way that the efficiency of the decontamination process is increased, and in this end. It is also possible to indicate additional additives.

This object is achieved in accordance with the invention by means of a decontamination agent of the first-mentioned type through the characteristics specified in the sub-clauses characterized in claim 1.

Through the addition of these substances, substances with a decontaminating effect that enter as a component of the foam-forming emulsion, whereby the emulsion in foamed conditions adheres to the sloped surfaces, but in unfoamed conditions run off. .

The decontamination is carried out with a decontamination liquid which can be a foam according to the invention, and the prepared eaves j1 or as yet unmixed emulsion components are proportionally blown with air to form a stable foam according to the invention. Pump or draw by suction through an intimate mixing device and apply or smear the foam onto the contaminated surface. Here, initially the viscosity of the fluid is greatly increased through the foaming process, and there is an advantage that before foaming, the liquid can be easily treated as a fluid with a relatively low viscosity.

Foam adhering to the surface being decontaminated increases the contact time of the decontaminant with the toxic substance and, like a blanket reservoir for the decontamination solution, inhibits rapid drying or washing away. At the same time, through the flow of emulsion to the surface of the wet foam and through the partial bursting of the foam bubbles, an internal mixing of the liquid and the carrying away of the decontaminated decontamination liquid from the contaminated surface result. This reduces the emulsion burden required for decontamination, the time required for action and the waste of personnel time, which is of decisive importance in situations of upheaval. The foamed emulsion formed has further improved surface temperature pJ properties, thereby promoting penetration into the porous and serrated surfaces of the emulsion.

The fatty alcohol polyglycol ethers and alkylphenol polyglycol ethers disclosed in the unpublished German patent application P30 47919, together with the characteristic amine oxides, as well as patent Alkyl or alkyl A, -717-#-polyglycol ethers as characterized in claim 1 also occur, whereby the optimum foaming conditions are on the hygrophobic side of the carbon alkyl/alkyl-aryl-polyglycol ethers. When the carbon content is between 10 and 20 carbon atoms, the degree of Etkin ratio is between 15 and 20 EOO.

The mixture of cleaning active substances according to the invention further comprises
0 ethylene, calcium hypochlorite and/or calcium chloride and water, i, t.

1-) Addition of other halodanized hydrocarbons such as IJ dichlorothane, ), 'J dichlorothylene, tetrachloromethane or complete addition of perchloroethylene, each of them or in mixtures, resulting in severe foaming in the system. It has the additional properties that make it possible to In a similar sense, isopro I? The addition of alcohols or other lower water-soluble alcohols and the addition of mineral oil distillates such as light benzene, heavy benzene, petroleum kerosene, diesel fuel and kerosene have a positive effect on the foam stabilization of decontaminated emulsions. have. Inbroknol and other lower water-soluble alcohols facilitate rapid mixing of concentrated solutions of cleaning actives according to the invention and suppress temporary gluing, which is possible upon dilution of Etquinate with water. 1. The cleaning-active substance mixture according to the invention can be used in urgent cases, in case of a shortage of the solvent component of perchlorethylene;
Partially or completely other standard solvents, halogenated hydrocarbons, lower alcohols, no! It offers the advantage of being able to be substituted by rough-in hydrocarbons.

These combustible paraffinic hydrocarbons also offer the particular advantage that after separation or de-emulsification from the depleted decontaminated emulsion, they can be incinerated together with the residual hazardous substances contained therein, being relatively environmentally beneficial. do.

The cleaning-active substance according to the invention furthermore has the advantage of lacking the precipitated anti-calcium phosphate, calcium silicate and calcium phosphate rapid release to high a degree of addition of alkali phosphates, alkali silicates and alkali carbonates. benefits and maintains remarkable foaming properties. Because the precipitated undissolved calcium phosphates, calcium silicates, and calcium carbonates occur in amorphous or fine particulate form, the reaction can be used if necessary for foaming and additional adjustment of the viscosity of the defoamed decontamination solution. This is because it can be done.

Cleaning according to the invention - activity'! The foam produced by a'J+ is stable for approximately 15 minutes, depending on the size of the foam;
After a certain period of time, the liquid part of the emulsion is completely and easily washed off the surface with water.

As indicated in the introductory part of Claims@Claim 1, the presence of foamy amine oxide does not limit the range (a) and/or (b) and/or or together with emulsifier components based on (c) and/or (d) are found to provide an optimal balance between sufficient emulsifier and good foaming properties.

Surprisingly, the highly ethoxylated, lower-foamed alkylphenol polyglycol ethers and fatty alcohols themselves based on the properties of claim 1(a) l(b) l(e) and (d) Polyglycol nitrates exhibit remarkable foaming power and shine in perchlorethylene/water/calcium hypochlorite or calcium chloride systems.
Alkali phosphates, alkali silicates or alkali carbonates used as viscosity modifiers, together with the halodanated hydrocarbons, lower alcohols, mineral oil distillates, and amine oxides according to the preamble of claim 1 as well. Can be replaced with salt.

An important property of the decontaminating fluid according to the invention lies in the fact that the tenside contained therein is stable in the decontaminating emulsion for a relatively long period of time and maintains its foaming power. Characteristics of claim 1 (+1)
