Definitions
- the present invention relates to a method for cleaning surfaces made of concrete, asphalt or the like, in particular airport runways, road surfaces, hall floors or the like, and to a cleaning agent for cleaning surfaces made of concrete, asphalt or the like, in particular airport slopes, road surfaces , Hall floor or the like
- EP 0 971 012 A1 discloses the use of oleic acid esters and a powder detergent for surfaces contaminated by hydrocarbons, in particular vegetable or mineral surfaces or animals. This detergent is particularly suitable for removing heavy oil residues from beaches, plants and animals.
- the present invention now aims to provide a method and a cleaning agent for cleaning such surfaces made of concrete, asphalt or the like.
- airport runways, road surfaces, hall floors or the like Available by a special process control or by the detergents used abrasive processing or impairment of the surface layer of the surface to be cleaned is avoided.
- the present invention is aimed at a cleaning agent which is completely biodegradable in comparison to known cleaning agents and which is harmless or non-harmful and not detrimental to the environment and the personnel handling the cleaning agent.
- the invention aims at a method which can be carried out in a reduced time compared to known methods.
- a method according to the invention for cleaning surface flakes made of concrete, asphalt or the like, in particular airport runways, road surfaces, hall floor or the like is essentially characterized in that cleaning and removal of contaminants, in particular adhering to the surface, such as, for example Rubber abrasion, oils, greases, carbon particles or the like, a cleaning agent causing dissolution or detachment of the contaminants is applied to the surface to be cleaned and then removed by rinsing with a rinsing fluid, in particular water, together with the dissolved contaminants and in particular m at least one collecting container is collected.
- a rinsing fluid in particular water
- a cleaning agent is applied to the surface to be cleaned for cleaning and removing dirt adhering to the surface in particular, which is then rinsed off after a comparatively short exposure time. This ensures that additional removal or damage to the cover layer or Wear layer of the surface to be cleaned is avoided, since the application of the cleaning agent, which dissolves or at least detaches the ms whose adherent soiling causes an impairment or action on the cover layer or protective layer of the surface to be treated is avoided. It can therefore be assumed that no mechanical stress or removal of elements of the uppermost cover layer of the surface to be cleaned is carried out when using the method according to the invention.
- the cleaning agent is applied, in particular sprayed on, to the surface to be cleaned under a pressure of at most 75 bar, in particular less than 50 bar, with the use of such a tool, at a comparatively low rate
- Pressurized cleaning agent is ensured that it reliably penetrates into any pores of the adhering contaminants and thus ensures a correspondingly quick and easy dissolving or detachment thereof.
- the comparatively low pressures ensure that there is no mechanical stress on the surface to be cleaned, as was the case in contrast to known processes in which work was carried out at significantly higher pressures.
- the procedure according to a further preferred embodiment is such that the cleaning agent and the soiling are removed by applying, in particular spraying, water under a pressure of at most 75 bar, in particular under a pressure between 50 and 60 bar. Similar to the Bringing the cleaning agent under a comparatively low pressure can also be found in the method according to the invention for rinsing to remove the cleaning agent together with the contaminants with water dissolved or detached therein under comparatively low pressure, so that not only the correct removal of the cleaning agent together with the soiling is ensured, but also a mechanical impairment or abrasion of the uppermost cover layer of the surface to be processed is prevented.
- hot water at a temperature between 45 and 70 ° C., in particular about 50 ° C.
- the cleaning agent be applied at a temperature between 30 and 60 ° C., in particular 40 to 45 ° C., such as this corresponds to a further preferred embodiment of the method according to the invention.
- the cleaning agent is allowed to act a maximum of 30 mm, in particular approximately 5 to 15 mm, as a further preferred
- the embodiment of the method according to the invention corresponds.
- the present invention aims not only to provide a method for cleaning surfaces made of concrete, aspnalt or the like, with which a treatment or cleaning of such surfaces can be carried out without mechanical abrasion, but rather it
- a cleaning agent for cleaning surfaces made of concrete, asphalt or the like in particular airport runways, road surfaces, hall floors or the like, is also provided, which is essentially characterized in that it consists of an aqueous Emulsion containing at least one higher methyl, ethyl, isopropyl carbonate and at least one polyhydric alcohol is formed.
- Such a cleaning agent is thus produced essentially on an organic basis or with a biochemical structure and composition and can therefore also be used without any problems and in compliance with corresponding guidelines regarding complete, biodegradability, so that the cleaning agent according to the invention can also be used in a free environment or next to green areas is harmless and even the surface or Floor detergent does not cause any environmental damage.
- the cleaning agent according to the invention can be produced in a correspondingly simple and cost-effective manner and, if appropriate, can also be matched to different purposes, such as different, known contaminants to be removed.
- composition of the cleaning agent according to the invention ensures that the substrates to be cleaned, in particular concrete slopes or asphalt roads, are not chemically attacked and thus damaged and, in addition, are reduced when using the cleaning agent for cleaning surfaces made of concrete, A-sphalt or the like Pressure can be worked or the procedural guidelines and environmental standards for the use of the cleaning agent can be easily adhered to without fear of excessive evaporation or decomposition of the cleaning agent under application conditions and thus without contamination of the environment.
- the higher methyl, ethyl and isopropylcarboxylates are present in the emulsion in an amount of 2 to 80% by weight in the cleaning agent according to the invention.
