Description

The invention relates to mechanical engineering, instrumentation, agriculture; It is used in the restoration and repair of machines and mechanisms, units in any industry.

Currently, for the preparation of parts before assembly, painting and preservation of finished products; flammable and toxic organic solvents or aqueous degreasing compounds containing surfactants are used for washing and degreasing.

The closest in essence and the achieved result to the claimed one is the analog - Detergent composition for degreasing metal parts, description to copyright certificate No. 667589, containing surfactants for cleaning metal surfaces: sodium tripolyphosphate, trisodium phosphate, soda ash, diproxamine 157, syntanol DT -7, carboxymethyl cellulose, sodium nitrite.

Known tool does not clean surfaces: abrasive, salt, coated, some paint and varnish pollution. The use of sodium nitrite sharply increases the toxicity of the detergent composition.

The aim of the invention is to increase the washing action and reduce the toxicity of technical detergent.

The goal is achieved in that the washing composition for cleaning contaminated surfaces of machine parts, containing sodium tripolyphosphate, trisodium phosphate, soda ash, diproxamine 157, carboxymethyl cellulose, according to the invention additionally contains sodium sulfate, industrial borax, oxalic acid, neonol in the following ratio of components , weight.%:

Sodium Tripolyphosphate 22-26

Trisodium phosphate 20-22

Soda Ash 17-20

Oxalic acid 5-7

Neonol 7-8

Borax technical 4-5

Sodium sulfate 8-10

Diproxamine 157 7-8

Carboxymethyl cellulose 2

For degreasing, aqueous solutions of a composition of a concentration of 4-8 %% are used.

Tests of the composition were carried out at mechanical repair plants for washing the engines of agricultural machines and tractors before repair after disassembly. Long-term use of the invention-composition in these plants, where the most difficult test conditions have shown the following results: reliably cleans surfaces from oil-grease, abrasive, salt deposits and certain paint and varnish contaminants, promotes coagulation of washer-cleaning waste, has an antifoam and corrosion inhibitor, completely fire and explosion proof, practically does not cause dryness and reddening of the skin upon contact, is non-toxic, and low-foaming process wastes do not surface t on the surface of the tank and settle in the form of sludge, facilitating the disposal and creation of low-waste, environmentally friendly technology in the manufacture and repair of machinery and equipment. The washing technology using this detergent refers to energy-saving technologies, due to the fact that at normal water temperature T = 20 ° C, used as a solvent in the composition, the detergent gives good results. Other known compositions and detergents require a solution temperature of T = 75 ° C, and only then do they show their washing abilities.

The Testing Laboratory Center at the State Committee of the Republic of Tatarstan for Sanitary and Epidemiological Surveillance checked the toxicity of the EFFECT technical detergent. There is a protocol No. 109 of the test results of September 17, 2001 - Appendix No. 1. The author of the invention developed the technical conditions for the production of this product - TU 2381-001-57235102-2002 and agreed by the State Sanitary and Epidemiological Service of the Russian Federation for the Republic of Tatarstan - Annex 2; 3. There is a Hygienic certificate - No. 16.11.03.238.P.000034.12.02. - Appendix No. 4. Based on these documents, LLC NPF "ARGUS" organized the industrial production of the technical detergent composition "EFFECT".

Table 1 shows the compositions of the proposed composition. Comparative test data of the proposed and known compositions are shown in table 2.

The composition is tested on metal plates of sheet steel in accordance with GOST 0709-72, rectangular, 100 × 100 mm in size, not more than 2 mm thick, the washing action and dirt removal rate are determined using a stopwatch and weighing on a balance accurate to 0.0001 g.

In the examples, a nitrogen-containing block copolymer of ethylene oxide and propylene oxide, diproxamine 157, was used as a defoamer, and synthetic polyhydric fatty alcohol-neonol was used as a highly effective surfactant. From the above data it follows that the composition "effect" has improved properties in comparison with the known composition.
