The technical result is an effective decontamination ability means while maintaining its high cleaning performance. table 2.

The invention relates to the field of chemistry, and specifically to a paste-like compositions of detergent designed for washing and decontamination of clothing from various tissue and polymer materials.

The technical field.

The invention can most effectively be used for washing clothes made of fabric and means of individual protection of the polymer materialmade of the disodium salt ethylendiaminetetraacetic acid (TRILON B), sulfonic acid (surfactant) and oxalic acid as a decontamination agent for cleaning surfaces made of different materials and fabrics from radionuclides (C. M. Gorodinsky, D. C. Holstein. Decontamination of polymeric materials. M: Energoizdat, 1981, S. 100).

However, this composition does not effectively remove mechanical and biological contamination with tissues. In addition, reusable wash it with detergent containing oxalic acid, leads to the destruction of the washed surfaces and fabrics.

Analogs of the invention are pasty detergents. Typical compositions pasty detergents include the following components: anionic surfactant, nonionic surfactant, nutritionist, perfumes, bleaches, water, and other components (A. A. Abramson. Surfactants and detergents. The Handbook).

Known detergent for washing containing surfactants (alkylsulfonate sodium, alkylsulfate primary fatty alcohols, ethylene glycol, sodium tripolyphosphate, carboxymethylcellulose, sodium chloride, sodium sulfate, proteolytic enzyme, poly is l, the odorant and water (RU RF PATENT 2050409, C 11 D 1/12 (1992), BI N 35 (1995)).

However, this cleanser has a weak decontamination ability and cannot effectively be used for washing clothes from radionuclides.

Known powder detergent containing Las, nonionic surfactant, sodium tripolyphosphate, metasilicate sodium, soda ash, carboxymethylcellulose, nitrobenzenesulfonate sodium, sodium sulfate, fragrance (RU RF PATENT 2089602, C 11 D 1/12 (1994), BI N 25 (1997)).

However, the tool does not have effective decontamination ability, in addition, contains a large amount of sodium sulfate and sodium tripolyphosphate, which leads to increased salt content in the wastewater, which is environmentally unfriendly.

Another disadvantage of this detergent is a powder state, which complicates the technology of its use and storage.

The closest in number of essential features of the present invention, we have chosen as a prototype is a synthetic detergent-based surfactants (complex disodium salt of monoamino sulfonterol acid, E. this product is intended for domestic use for hand washing and machine products from various tissues.

Known means consists of the following components taken in the ratio, wt.%: Comprehensive disodium salt of monoamino sulfonterol acid - 6-10 Alkilbenzolsulfonol sodium - 1-2 Sodium liquid glass - 4-6 soda ash - 1-3 Tripolyphosphate, sodium - 2-5 Formalin technical - 0,15-0,3 ethylene Glycol - 0,8-1,5 Optical bleach - 0,2-0,3 Perfume perfume - 0,1-0,2
Known detergent has a good washing capacity.

However, its use in the washing of clothing enterprises of the nuclear industry is inefficient as a decontamination tool when removing radionuclides from contaminated surfaces.

Disclosure of the invention.

Task to be solved by the present invention is directed, is the creation of a pasty detergent with effective decontamination ability, while maintaining a high cleaning performance.

The solution of the stated problem with achievement of the technical result is ensured by the fact that pasty detergent and deactivating means includes Las sodium, sodium silicate, soda ash, sodium tripolyphosphate, perfume perfume and water. It also contains the hydroxy is th acid, oksietilidendifosfonovaya acid, carbonatization, ammonium citrate, tetraborates sodium, enzyme, bleach, and a catalyst for hydrolysis, in the following ratio, wt.%:
Las sodium 4-6
Ethoxylated alkyl phenol - 3-4
Salts of fatty acids, alkali metal - 6-10
The disodium salt of ethylendiaminetetraacetic acid - 6-10
Hydroxyethylenediphosphonic acid - 2-3
Carbometalation - 0,2-0,3
Sodium silicate - 2-3
Soda ash - 3-5
Sodium tripolyphosphate - 2-3
Citrate ammonium 1-2
Tetraborates sodium - 2-3
Enzyme - 0,6-1,0
Bleach - 6-10
The catalyst of the hydrolysis - 0,01-0,05
Perfume perfume - 0,1-0,2
Water - the Rest
The essence of the present invention is the introduction of more in the decontamination composition additives, chelating agents disodium salt ethylendiaminetetraacetic acid (TRILON B), oksietilidendifosfonovaya acid (HEDP), which interact with the radionuclide, form soluble complexes with them and translate them into a solution. It facilitates the efficient removal of radioactive contamination from treated surfaces. In addition, the introduction of the detergent Atri and as a catalyst for hydrolysis - potassium permanganate and/or douglaston tin, results in unexpected enhancement effect of washing and decontamination capacity of all components of the mixture.

Prepare cleaning and decontamination agent in the chemical reactor by mixing the components in the above ratio without heating and cooling.

The disodium salt of ethylenediaminetetraacetic acid (TRILON-B) (TU 113-04-260-87) and hydroxyethylenediphosphonic acid (HEDP) (TU 6-09-5372-87) are the decontamination agents and are available in the industry.

Decontamination agents form soluble complexes with radionuclides and translate them into a solution from the surface of various materials.

Las sodium (TU 2481-037-04689375-95), ethoxylated alkyl phenol (GOST 8433-31), salts of fatty acids alkali metals ("soap fat") are surface-active substances (surfactants) and provide the ability of the composition.

Used in the tool surfactant produced by domestic industry.

Sodium silicate (GOST 13078-81), soda ash (GOST 5100-85), sodium tripolyphosphate (GOST 7234-79), tetraborates sodium (GOST 84-29-77) are buffer systems, a weak complexing agents and synergetica capacity of the facility as a whole.

Carbometalation (TU 6-55-221-1453-96) prevents the reverse deposition of mud particles on the washing surface and simultaneously saguday composition.

Bleach / peroxide, oxidizes mud particles facilitates their cleavage and enhances the ability of the proposed structure.

Enzyme - med. bile affects the acceleration of the cleavage reaction grease.

As a catalyst for hydrolysis using potassium permanganate and/or douglaston tin. The catalyst speeds up the process of cleaning from mechanical impurities.

Tests of means was carried out by washing in the washing machine "PL-50" at a temperature of 30-100oC. Duration of washing 15-45 min, followed by rinsing. The flow of funds is 20-30 g per 1 kg of dry clothes.

The degree of detergency of the proposed drug was determined visually using a magnifying glass on the time of removal of contamination. The value of detergency is expressed in % of the captured contaminants.

Decontamination ability was determined by the device, showing the level of radioactive contamination of the subject before and after washing, which is expressed by the coefficient of decontamination is ToDeux.

Implementation examples of the invention are shown in table pointof below and above (examples 4*,5*) leads to a reduction in cleaning and decontamination ability of the proposed drug.

In particular, the reduction in the content of the surfactant reduces the degree of separation of mud particles from the surface, and increasing the number of surfactant leads to increased foaming, which complicates the process of enveloping mud particles surfactant.

The reduction decontamination additives leads to incomplete removal of radioactive particles. The increase in the number of decontamination additives and other components leads to increased salt formation in the wastewater, which is undesirable from the point of view of ecology.

Thus, the proposed invention provides the above technical result.

The average decontamination factor 1.5-5.0 times higher than these figures when applying the known detergents.

In addition, the consumption of the proposed drug for 1 kg of dry clothing or PPE 3 times less than when using the prototype.

Therefore, the salt content in spent far the solution is less than when using known compounds.

Quality usteriana from mechanical and biological contamination are not visually different from the quality of usteriana when the application of the known compounds.

In addition, savla the shaped washing and decontaminating a vehicle according to the invention exhibits a high decontamination ability in the processing of various surfaces of the fabric and polymeric materials and can be used for cleaning and decontamination of protective clothing and personal protective equipment for the nuclear industry.
