Description

 The invention relates to basic technological materials, namely technological universal detergents used for interoperational washing and purification processing of metal products in machine and instrument making and household chemicals.

 Detergents are known that include surfactants, sodium sulfate, soda ash, sodium tripolyphosphate, trisodium phosphate, sodium silicate, borax, etc. (1).

 The prepared aqueous solutions based on them require heating to high operating temperatures, which consumes electricity, non-oranic waste water solutions do not self-clean and create unpleasant odors, the compositions themselves contain a lot of scarce raw materials.

A detergent is known, which is used mainly for cleaning a metal surface, containing soda ash, water glass, sodium tripolyphosphate, polyethylene glycol ether of synthetic primary fatty alcohols of fraction C ₁₀ -C ₁₈ and sodium alkyl sulfate (2).

 The known tool does not provide sufficient cleaning of the metal surface and has a low degree of cleaning when washing workwear.

The closest tool to the claimed combination of essential features is a tool for cleaning the metal surface "TMOK-1P", containing, by weight. polyethylene glycol esters of monoethanolamine synthetic fatty acids of fraction C ₁₀ -C ₁₈ 7-9; sodium sulfate 10-12; sodium tripolyphosphate triliphosphate 40-42; carboxymethyl cellulose 16-18; phosphoric acid or its salt is 1.5-2.5; perfume 2.5-3.5; defoamer 0.5-1, soda ash the rest (3).

 The known device has a high degree of purification (up to 100%), the intensity of cleaning a metal surface, rather low foaming (1-2 points), however, its use requires preliminary heating of the working solutions of the product, which leads to high energy costs. In addition, the tool is used to clean only a metal surface.

 The objective of the invention is the creation of a universal detergent both for cleaning a metal surface and for washing coarse work clothes at low temperatures using the product and having self-cleaning of spent compositions after washing and cleaning.

The objectives of the invention are achieved in that a detergent containing polyethylene glycol ether of monoethanolamine synthetic fatty acids of fraction C ₁₀₀ -C ₁₆ , sodium sulfate, sodium tripolyphosphate carboxymethyl cellulose and soda ash, according to the invention further comprises a liquid sodium glass, activated iodine-based charcoal, oxyethylenated monoalkylethylene of propylene trimers and the product of hydrolysis of a mixture of silane chlorides with a ratio of methyl radicals to silicon of 1.3-1.7
To clean the metal surface and wash coarse workwear (miners' clothes), dry components are pre-mixed with the ratio of the components indicated in the table in accordance with the formula, then an aqueous 5% working solution is prepared from them. The experiments were carried out in laboratory and semi-production conditions at the washing complex, where the modes, samples and cleaning methods were close to production. The intensity of the removal of contaminants was determined by the difference in mass of the sample before and after washing and cleaning treatment. The samples were production details from black carbon steels, cast iron with various impurities, and miners' overalls (Table 1).

 The energy consumption for the operational heating of aqueous working media was estimated indirectly by the performance of the detergent, the intensity of the removal of contaminants at room, medium and maximum temperatures according to the generally accepted method. Assessment of the duration of the cleaning of water working environments was carried out according to the accepted practice of water conservation laboratories. The results are presented in table. 2.

An analysis of the results of washing and cleaning treatment with aqueous solutions based on the claimed product, having the technical name "TMOK-6PU", shows that steel parts with the presence of oil-abrasive films, heavily contaminated with oils, dirt and slags, work clothes are effectively cleaned with water tools at 25-40 ^o C. As a result, there is no need to spend large amounts of electricity on washing and cleaning operations. In addition, there is intensive self-cleaning of the spent formulations of the product after its use.
