Definitions
- the present invention relates to a cleaner for technical surfaces which can be used in the dipping and spraying process and which has demulsifying properties.
- Demulsifying means that fats and oils purified from the technical surfaces are not or only to a limited extent emulsified in the detergent bath. Rather, fats and oils settle in calming zones on the surface of the detergent bath and can be mechanically removed. This extends the service life of the cleaner bath.
- Technical surfaces are surfaces of technical components such as household appliances, vehicle bodies or parts thereof or parts to be understood, which are incorporated in technical equipment.
- the technical surfaces can be plastic surfaces or painted metal parts.
- surfaces of unpainted metal parts in particular of parts of iron, steel, zinc, galvanized steel, aluminum, magnesium and alloys, which consist mainly of one of said metals.
- fats and oils should be removed from the surfaces; on the other hand, they should be suspended or emulsified in the cleaner at most to a small extent.
- the choice of available surfactants that make a detergent both demulsifying and good cleaning is limited. Therefore, there is a need to identify other surfactants that improve the performance of industrial cleaners in terms of demulsifying properties and cleaning performance. For the broad applicability of the cleaner sprayability should also be given.
- the present invention relates to the use of nonionic surfactants of the alkyl alcohol ethoxylate / propoxylate type in aqueous industrial cleaning solutions, characterized in that the nonionic surfactants carry 8 to 10 C atoms in the alkyl radical and 5 to 11 ethylene oxide and 1 to 7 propylene oxide units exhibit.
- aqueous technical cleaning solutions or “cleaners” for short, are used in particular in the industrial production of goods, in particular non-painted metal, for example, vehicles or vehicle parts.
- the inventive use of said nonionic surfactants may be characterized in that the technical cleaning solutions are used at a temperature of 40 to 80 0 C, preferably from 50 to 70 0 C in the spray process. However, they can also be used in the dipping process, wherein the same temperature ranges are preferred. Preferably, at least a portion of the cleaning solution after application in the spraying or dipping process to a calming zone, in which separate oils and / or fats from the aqueous cleaning solution. These can be removed by known technical means from the surface of the cleaning solution, oils and / or fats, which are cleaned from the technical surfaces, thereby do not accumulate in the cleaning solution. This extends the service life of the cleaning solution.
- the said nonionic surfactants are preferably used in such a way that the cleaning solutions contain about 0.01 g / l to about 3 g / l of said nonionic surfactants. It is preferred that the said nonionic surfactants according to claim 1 constitute at least 50 wt .-%, preferably at least 80 wt .-% and in particular at least 90 wt .-% or at least 95 wt .-% of the total surfactant content of the cleaning solution. It is particularly preferred that the cleaning solution contains no other surfactants than the nonionic surfactants to be used according to the invention.
- the present invention relates to an aqueous cleaning solution for use in the cleaning of technical surfaces by spraying or dipping process containing nonionic surfactants of the alkyl alcohol ethoxylate / propoxylate type, characterized in that the nonionic surfactants 8 to 10 C atoms in Have alkyl radical and 5 to 11 ethylene oxide and 1 to 7 propylene oxide units.
- this aqueous cleaning solution contains about 0.01 g / L to about 3 g / L of said nonionic surfactants. It is also preferred that said nonionic surfactants constitute at least 50% by weight, preferably at least 80% by weight, of the total surfactant content of the cleaning solution. It is even more preferred that these nonionic surfactants contain at least 90% by weight and in particular at least 95% by weight of the total Make up the surfactant content of the cleaning solution. The stated nonionic surfactants may even be the only surfactants in the aqueous cleaning solution.
- inventive aqueous cleaning solution it is also preferred for the inventive aqueous cleaning solution that they additionally at least one alkaline substance, preferably selected from alkali metal hydroxides, alkali metal borates, alkali metal carbonates, alkali metal silicates, alkali metal phosphates and organic amines, especially alkanolamines, in such Amount contains that the pH of the cleaning solution in the range of 9 to 13, preferably in the range of 10 to 12.
- the aqueous cleaning solution may contain one or more of the following components: a) borate in an amount corresponding to 1 to 10 g / l of dipotassium tetraborate, b) orthophosphate in an amount corresponding to 0.5 to 10 g / l of tripotassium phosphate, c) di-, tri- or polyphosphate in an amount corresponding to 0.5 to 10 g / l tetra potassium diphosphate, d) silicate in an amount corresponding to 0.05 to 2 g / l SiO 2 , e) NaOH or KOH in one Quantity corresponding to 1 to 10 g / l KOH.
- borate in an amount corresponding to 1 to 10 g / l of dipotassium tetraborate
- orthophosphate in an amount corresponding to 0.5 to 10 g / l of tripotassium phosphate
- di-, tri- or polyphosphate in an amount corresponding to 0.5 to 10 g
- silicates are often characterized by their "modulus", ie the molar or weight ratio of SiO 2 to alkali metal oxide.
- silicates having a molecular weight so defined be used in the range of about 1, 5 to about 4, in particular in the range of about 2.5 to about 3.7.
- auxiliaries or active substances may be present, in particular organic complexing agents and / or corrosion inhibitors.
- the pH is preferably in the range of 10 to 12.
- a new cleaner for technical surfaces is provided, which is optimized in its property profile with respect to demulsifying properties and cleaning performance in immersion process.
- Spraying is given. It can be used in particular in the manufacture of vehicles and vehicle parts. Parts of this type are contaminated for their manufacture and manufacture, in particular with anticorrosion fats or oils, forming aids such as rolling or drawing oils and fats, or with coolant lubricant residues. Such impurities are removed by spraying or dipping method according to the requirements of the metal surfaces. Due to the demulsifying properties, they can easily be mechanically separated from the cleaning solution.
