Definitions
- the invention relates to a composition according to the preamble of independent claim.
- the composition is used for treatment of surfaces of flat objects, whereby by one with the composition treated surface in a number at least partially superimposed, flat objects a predetermined separation point is formed on which the number can be deliberately separated.
- the flat Objects consist for example of paper, cardboard, fabric, felt or plastic.
- the number of flat objects to be separated is, for example a multi-page printed product made of paper, plastic or cardboard, that can be opened at a certain point, or it is a stack or one scaled formation of printed products or of flat objects made of cardboard, fabric, felt or plastic, from which stack or scaled Formation, for example, by separating at a certain point remove a certain number of items.
- Measures to reduce the coefficient of friction are, for example a treatment with a lubricant or a smoothing of at least one of the surfaces to be moved against each other or the positioning proposed a slide film between the objects to be moved.
- the object of the present invention is to provide a composition for Treatment of surfaces of flat objects to create which Composition in the above method is applicable to the predetermined Create separation point. This task is solved by the composition, as in the claims of the present patent application is defined.
- the procedure described in the parallel application is based on the knowledge that that the liability between superimposed, flat objects can be increased by static charging of their surfaces.
- the parallel registration procedure is now used on the surfaces of the superimposed, flat objects generated by static electricity by a substantially perpendicular to the main surfaces of the objects aligned electrical DC field. Through the The effects of the field are aligned across the main dipoles or charges shifted and focus on the two surfaces each of the items ever positive or negative charges. Through this Charges are created between the surfaces of various objects electrical attractions that increase mutual liability.
- composition according to the invention represents such a mixture of an antistatic agent and a lubricant, the mixture may have additional, further constituents (e.g. luminophore).
- FIG. 1 shows a diagram of the successive steps of the method using the example of a stack 1 consisting of five superimposed, flat objects 2, the upper two objects being to be moved relative to the lower three objects in order to separate the stack.
- the predetermined separation point is therefore between the upper surface of the third object and the lower surface of the fourth object in the stack 1.
- a antistatic agent 3 or preferably with the composition according to the invention, which contains an antistatic agent and a lubricant, treated, for example coated.
- the one treated with composition 3 according to the invention forms Surface one of the surfaces to be moved against each other. It is of course also possible and in certain applications also advantageous, not only the one surface of the separation point but both surfaces involved at the separation point with the composition to treat.
- the stack 1 is then exposed to a DC field, the field lines aligned substantially perpendicular to the major surfaces of the objects are.
- the stack between two electrodes 10 for example performed between two plates or rods, between which one there is a constant potential difference.
- the field Dipoles aligned or charges shifted in the flat objects such that there is between the two surfaces of an object builds up a potential difference or a static charge on the surfaces, like that in Figure 1 schematically by small plus and minus signs is shown. These charges are on superimposed surfaces of Opposing neighboring objects, creating electrical attraction arise between objects.
- a displacement force (arrow 11), which acts on the stack surface, for example, and a component parallel to the main surfaces of the objects on the stack 1 applied.
- this displacement force 11 the two surfaces in the stack that least cling to each other and between which the slightest static friction acts against each other, even if the force does not attack precisely at the point of separation, but for example at the Stack surface.
- the antistatic contained in the composition according to the invention is an antistatic known from the plastics industry Medium. These are, for example, conductive particles (e.g. Carbon black, mica coated with nickel, steel fibers or Aluminum plate or that offered by the Merck company in Darmstadt conductive pigment Minatec®), which are finely distributed in a matrix, around ionic compounds (e.g. quaternary ammonium salts), surface-active Substances (e.g. glycol esters, glycol ethers or esters and salts of Fatty acids) or hygroscopic substances (e.g. glycerin or polyglycol), which as such or in the form of aqueous or alcoholic solutions for Application come.
- conductive particles e.g. Carbon black, mica coated with nickel, steel fibers or Aluminum plate or that offered by the Merck company in Darmstadt conductive pigment Minatec®
- surface-active Substances e.g. glycol esters, glycol ethers or esters and salts of Fatty acids
- the lubricant contained in the composition according to the invention is one in the above-mentioned method according to the patent specifications CH-440339 and CH-534588 applicable lubricant.
- It is for example a wax that is a natural wax (e.g. beeswax), a chemically modified, originally natural wax (e.g. hydrogenated Jojoba wax, paraffin wax made from petroleum) or a synthetic one Wax (e.g. polyethylene glycol wax) can be a highly viscous silicone oil or a suitable plastic (e.g. Teflon).
- the components are used to produce the composition according to the invention just mixed together, which is why some of the components optionally in a liquid or at least plastic state bring is.
- the finished composition is liquid or pasty or solid in Pieces or as granules or powder.
- the treatment of the surfaces with the composition can for a liquid or powder composition or a composition in molten state can be spraying or application with a roller, where appropriate aftertreatment of the treated surfaces, for example with heat, is necessary to the composition on the Fix surface.
- Solid compositions are advantageous applied by direct rubbing on the surface to be treated or by rubbing with the help of a brush.
- compositions according to the invention exist for example from a wax or from a plastic (sliding component), are embedded in the conductive particles (lead component).
- Such Compositions are very simple, for example on paper surfaces rubable.
- a specific such composition variant which is particularly suitable for the treatment of printed products because they are applied to paper invisible and otherwise barely detectable by the reader consists of Paraffin wax and the already mentioned conductive pigment Minatec®, whereby the weight proportion of the wax preferably between 55 and 75%, in particular is between 66 and 67%.
- composition according to the invention can be applied by spraying , it can also contain a solvent or water.
- composition according to the invention by mixing any of the antistatic agents mentioned above with any lubricant.
- advantageous compositions both in terms of components and with regard to concentrations of the individual components
