Definitions
- the removal of electrostatically bound residues from plastic surfaces is particularly important in the industrial sector, for example when cleaning secondary food packaging such as yoghurt trays, beverage crates or transport boxes for bread, meat, etc., from painted surfaces such as from motor vehicles and generally when cleaning plastic surfaces such as window frames , Linings of ventilation shafts or wall cladding as well as foils, textiles etc. are associated with difficulties, since the respective objects with plastic surfaces attract the dirt shortly after manufacture or cleaning due to their charging.
- the inorganic constituents of the dust (soot, carbonates, silicates), which make up more than 60% by weight of the dust weight, adhere firmly to the surfaces and cannot be completely removed with conventional cleaners even after intensive treatment.
- External antistatic agents for the surface treatment of statically chargeable objects are also described comprehensively in the prior art and have a number of advantages over “internal antistatic agents”: they are inexpensive to manufacture, are used in highly dilute solutions and, owing to the periodically repeated use, do not have to be extremely expensive have great long-term stability and can also be used on almost all statically chargeable surfaces. "External antistatic agents” increase the surface conductivity and thus enable an improved flow of charges. Outer antistatic agents are generally substances with at least one hydrophilic part of the molecule and give a more or less hygroscopic film on the surfaces.
- surface-active antistatic agents can be broken down into nitrogen-containing (amines , A ide, quaternary ammonium compounds), phosphorus-containing (phosphoric acid esters) and sulfur-containing (alkylsulfonates, alkylsulfates) antistatic substances, and non-surface-active compounds can also be used as antistatic agents - the best known is the use of carbon black, silicon dioxide, aluminosilicates and metal oxides both as internal and also as an external antistatic.
- External antistatic agents are usually applied to the surfaces to be treated using solutions in water, alcohols, petrol, chlorinated hydrocarbons, etc. by brushing, dipping or spraying. Economic, ecological, occupational health and occupational safety considerations play a role in the selection of solvents and antistatic agents.
- Common external antistatic agents which are used for surface treatment often have the disadvantage of forming precipitates with anionic cleaning agents on account of their content of cationic compounds, so that they have to be used in a subsequent step. For use in dishwashers and spraying machines, these agents must be low-foaming, wet the surfaces well and dry quickly.
- Common external antistatic agents have only minor effects with regard to polarizability and electrical conductivity of the treated surfaces. In addition, the long-term effects of commercially available antistatic agents are usually poor.
- statically chargeable surface refers to horizontal and non-horizontal surfaces which, owing to insulating Material properties tend to charge.
- this includes plastics, in particular thermoplastics and thermosets, in which this problem is particularly pronounced.
- DE 197 07 650 recommends antistatic cleaning agent concentrates which, when added to water, provide an antistatic cleaning solution, characterized in that they contain: a) 1 to 12% by weight of one or more alkoxylated primary or secondary amines, b) 1 up to 10% by weight of a fatty acid salt, c) 2 to 12% by weight of one or more low-foaming nonionic surfactants and the remainder water or an aqueous solution of further auxiliaries and active ingredients.
- DE 197 07 650 recommends a method for cleaning statically chargeable surfaces, in which an antistatic aqueous cleaning agent is applied to the statically chargeable surfaces to be cleaned and is then allowed to run off.
- the antistatic aqueous cleaning agent to be used in this process is obtained by diluting an antistatic cleaning agent concentrate with water.
- DE 197 07 650 acts as an antistatic, alkoxylated primary or secondary amines. These are distinguished by their usability both as internal antistatic agents and as external antistatic agents in cleaning agents of the present invention.
- DE 197 07 650 With the cleaning agents described in DE 197 07 650, common contaminants can be removed. However, if there are impurities that adhere to it due to interactions with the electrostatically charged surface, then the cleaning effect of the agents described in DE 197 07 650 is not sufficient. Accordingly, the disadvantage of DE 197 07 650 is that the method mentioned is not aimed at the removal of electrostatically adhering residues. On the other hand, it is disadvantageous that special, again antistatic components have to be used to implement DE 197 07 650.
- the process should be designed so that the use of antistatic components should not be essential for the success of the process.
- the present invention relates to a method for cleaning plastic surfaces contaminated with electrostatically bound residues by treatment with water and / or aqueous cleaning solutions, in which, prior to the treatment mentioned, the plastic surfaces of the plastic containers with a liquid agent containing at least one non-polar component with paraffinic properties , are pretreated.
- the apolar component mentioned with paraffinic properties is selected from compounds which have a dielectric constant between 1 and 10, preferably between 1 and 6.
- the dielectric constant mentioned can be determined by customary measurement methods, in particular by measurement with a decameter under the conditions 50 Hz and 20 ° C. according to DIN 53483.
- the plastic surfaces come from plastic containers, the pretreatment mentioned being carried out as soon as possible, preferably immediately after the production or printing of the plastic containers, which is to be understood as a point in time at which there is still no visible contamination.
- the pretreatment preferably takes place within 24 hours after production or printing. Since beverage crates are usually printed, a preferred interval for the pretreatment in this case would be the period within 24 hours after the printing ink has dried
- the method according to the invention can also be preferred in the method according to the invention to carry out the aforementioned pretreatment shortly before the treatment of the plastic surfaces, in particular to carry out plastic containers with water and / or aqueous cleaning solutions, with “shortly before” preferably being a time interval of a few seconds up to a time interval sufficiently short before the treatment of the plastic surfaces with water and / or cleaning solutions, so that a non-drip even film is spread on the surface.
- the pretreatment mentioned can of course also take place at any time between the production or printing and the treatment of the plastic containers mentioned with water and / or aqueous cleaning solution.
- apolar component with paraffinic properties is selected from paraffin, terpene, oil or oil-like compounds and polymers or mixtures of these components, compounds such as orange terpenes or pure paraffin being particularly suitable.
- the apolar component mentioned preferably makes up a proportion of 1 to 100% by weight, particularly preferably 50 to 100% by weight, based on the total liquid agent to be used for the pretreatments, additional components preferably being selected from fatty alcohols and their derivatives, fatty acids and their derivatives are contained.
- liquid pretreatment agent mentioned is sprayed onto the plastic surfaces, preferably in undiluted form.
- a further preferred embodiment of the method according to the invention includes that the treatment of the pretreated plastic surfaces to be carried out according to the invention with water and / or aqueous cleaning solutions takes place at a temperature of 35 to 90 ° C.
- this aqueous treatment step the residues, including the apolar components, are preferably detached from the plastic surface.
- This treatment step is preferably carried out in a conventional crate washer or corresponding continuous cleaning machines carried out.
- the duration of the treatment step is preferably between 30 seconds and 15 minutes.
- a cleaning agent concentrate is dissolved in water in a weight ratio of 1: 1000 to 1:50, preferably in a weight ratio of 1: 200 to 1: 100, to produce the same. Then this solution is preferably applied to the surfaces to be cleaned or the objects to be cleaned are immersed in this solution, the solution then being allowed to run off.
- the detergent concentrate to be diluted a) 1 to 12% by weight of one or more alkoxylated primary or secondary amines, particularly preferably ethoxylated secondary amines, b) 1 to 10% by weight of a fatty acid salt, particularly preferably one Triethanolamine salt of a C 8 -0 0 fatty acid, which was very particularly preferably synthesized before or during the manufacture of the detergent concentrate from triethanolamine and the fatty acid, and c) contains 2 to 12% by weight of one or more nonionic surfactants.
- the cleaning agent concentrate to be diluted contains, as additional components, complexing agents, preferably EDTA or NTA, and also further auxiliary or active substances, further alkalis, builder substances, further anionic and nonionic surfactants, enzymes, preservatives, oxidizing agents, Dyes and / or perfumes are present.
- complexing agents preferably EDTA or NTA
- auxiliary or active substances further alkalis, builder substances, further anionic and nonionic surfactants, enzymes, preservatives, oxidizing agents, Dyes and / or perfumes are present.
- Another object of the present invention is a method for treating plastic surfaces, in particular plastic containers for the subsequent improved removal of electrostatically bound contaminants, in which the surfaces of the plastic containers are pretreated with a liquid agent containing at least one non-polar component with paraffinic properties.
- a liquid agent containing at least one non-polar component with paraffinic properties containing at least one non-polar component with paraffinic properties.
- the sample tests were carried out on beer crates, which were produced in-house by a large German brewery and made available for the tests.
- the beer crates were yellow crates with a capacity of eleven 0.5 L beer bottles each.
- the cleaning solutions used for the aqueous alkaline cleaning are contained in Table 1. To check the cleaning effect, these solutions were prepared in the laboratory and pumped around with a pump. The temperature of the solutions was around 50 ° C. during the test. In the tests, the solutions to be examined were rinsed through a hose from a distance of about 0.2 m over a period of about 3 minutes to a visibly heavily soiled area of the beer crates contaminated with electrostatically bound residues. In the tests, the mechanical action corresponded approximately to the mechanical action which would normally be present when the corresponding surface was rinsed off with tap water.
