Description

Alkaline rinse cleaner

Technical field

The technical solution relates to an alkaline rinse cleaning agent based on an aqueous solution with a high degreasing effect, intended especially for industrial plants for washing metal surfaces, especially before their further surface treatment.

BACKGROUND OF THE INVENTION

Until now, petroleum based cleaning and degreasing agents, such as industrial gasoline, have been commonly used for washing metal surfaces, for example in car repair. The disadvantage of these agents, however, is their negative impact on the environment and their flammability.

Also known are cleaning and degreasing agents with an effective washing component based on alkali metal polyphosphates, such as pentasodium triphosphate, usually in an amount of 20 to 60% by weight. However, these cleaners and degreasers often have a low effect on heavily soiled surfaces and therefore enrich the special purpose of their use according to their purpose. However, these special ingredients may, in many cases, impede the universal use of the cleaning compositions in which they are contained, or increase the effect of the cleaning compositions inadequately.

From the Czech utility model CZ 11210, a cleaning and degreasing agent is also known, in particular for heavily soiled areas containing an active washing component and a plasticizer with the addition of a perfume component and a colorant, which further contains 0.5 to 25 wt. % fatty acid condensation product with ethylene oxide, 0.5 to 25 wt. % alkylbenzenesulfonic acid salt and 0.5 to 25 wt. the condensation product of alkylphenol with ethylene oxide. In this case, however, the cleaning and degreasing agent is generally in powder form, in which it can be used for extremely dirty areas.

The essence of the technical solution

The above-mentioned disadvantages of the prior art are largely overcome by an alkaline rinsing cleaning agent based on an aqueous solution with a high degreasing effect, especially for industrial use, according to a technical solution comprising 1.0 to 8.0 wt. % Of 2-butoxyethanol, 0.5 to 5.0 wt. % sodium hydroxide, 3.0 to 20.0 wt. % surfactants, 6.0 to 15.0 wt. excipients, the remainder of the solvent.

The advantage of the alkaline rinse cleaner according to the invention is its versatility and high efficiency, being a suitable filling in industrial dishwashers, very well dissolves dirt, grease and petroleum products, reliably removes preservative and emulsifying oils before surface treatment of materials. It does not contain chlorinated solvents or petrol and is a water-borne, non-flammable, non-toxic detergent. Dilution depends on the nature of the dirt to be removed and the cleaning technology, it can be applied by spraying, painting or immersion, the exposure time is 1 to 60 minutes. The dilution ranges from 1: 2 for heavily soiled areas to 1: 200 for lightly soiled areas. After application, the surface to be treated should be thoroughly rinsed with water.
