Definitions
- the present invention relates to a process for the continuous inner coating of an extruded hollow profile strand. Furthermore, the invention relates to a device for removing excess coating agent from the chambers of a hollow profile.
- EP 0 530 617 A1 discloses a process for the continuous inner coating of an extruded hollow profile of thermoplastic material. Therein, a hollow profile strand is led immediately after extrusion on a curved path through a supply of a liquid coating agent. After passing through the coating agent of the hollow chamber strand is carried out until the entrained excess of the liquid coating agent has partially run back into the supply.
- a problem of this method is the slow flow rate of the coating agent. As a result, more coating agent remains in the hollow chambers of the strand as needed for uniform film formation on the inner walls. Such an excess leads to the formation of relatively thick and slowly drying films or also to the formation of flow edges, streaks and so-called "flow noses". As a result, the sawn from the hollow profile sheets are wet. Although the sawn plates are treated at 60 ° C in the annealing oven for application of an outer laminating film, but this treatment is not sufficient to remove excess coating agent. The previous solution was to put the plate on a trolley with wheels, which tilts the plate in the transverse and longitudinal direction, whereby a portion of the remaining liquid expires.
- the plates are then connected to a hot air blower, whereby in a batch process, the plates can be dried individually.
- the plates In the usual amounts of coating liquid remain crystalline paragraphs in the hollow profile by this method, which occur as white spots especially on the two end faces of the plate. In order to remove these residues, 300 mm must be sawed off on both sides of the plate and fall as material waste.
- No. 5,681,390 describes a spray booth for the spray coating of objects whose inner walls are cleaned with wiper rails of finely divided material. The wiper rails on the inner walls are moved by means of magnets from the outside.
- the object of the invention was also to provide a method in which caused by visible or crystalline coating residues cutting to hollow profile can be avoided as possible.

The arrangement in the region of the slope of the path causes the stripped Coating agent flows back into the coating agent supply and is available for the further coating process.
- a Flusstechniksabstreifer is used, which in addition to the described wiper lip and the magnet also comprises a lip of a material impregnated with the coating material.
- Such a lip is located in the direction of the path of the hollow profile strand behind the wiper lip and touches as well as this one or more inner walls of the hollow chamber. During the course of the process, the lip is impregnated by liquid coating agent and thus causes a particularly uniform distribution of the coating agent on the inner walls of the hollow chamber.

- the magnet, counter magnet or magnetizable material itself forms the body of the liquid scraper, to which the scraper lip is attached.
- a Flusstechniksabstreifer is used, which is formed from a non-magnetic body to which the magnet, counter magnet or magnetizable material, the wiper lip and possibly also a liquid-impregnable lip are attached.
- the non-magnetic body of the liquid scraper may in principle consist of any material which is substantially inert to the coating agent.
- Preferred materials are plastics such as poly (meth) acrylate, polystyrene, polycarbonate.
- the method according to the invention is configured in such a way that the inner wall of the hollow chamber is touched exclusively by one or more wiper lips and, if appropriate, additionally by a liquid-impregnable lip. This is achieved by a projection of the existing lips on the magnet or magnetizable material or the body of the scraper.
- the magnet, countermagnet or magnetizable material of the liquid scraper and the possibly present non-magnetic body do not touch the inner walls, since a mechanical action of these components on the inner wall is undesirable because of possible damage to the coating film.
- a Flusstechniksabstreifer is used, are attached to the magnetic or non-magnetic body, one or more rotatable rollers.
- the Flusstechniksabstreifer is stored in the hollow chamber.
- the rollers are mounted so that they are at least the.
- the rollers may in principle be made of any material that is substantially inert to the coating agent. Preference is given to plastics, such as e.g. Poly (meth) acrylate, polycarbonate, polystyrene or polyamide.
- one or more inner walls of the hollow chamber touches both with the wiper lip and the possibly existing liquid-impregnable lip as well as with the rollers.
- the rollers are rotated.
- rollers act as spacers between the wall of the hollow profile chamber and the magnet, counter magnet or magnetizable material or the body of the liquid scraper. Due to the defined distance, it is possible to achieve a particularly uniform pressure of the wiper lips on the wall and a particularly uniform wiping.
- continuous films are formed on the inner walls of the hollow chamber whose film thickness in the wet state is usually between 0.05 .mu.m and 3000 .mu.m and preferably between 2.5 .mu.m and 3.0 .mu.m.
- the film thickness is generally between 50 nm and 300 nm and preferably between 60 nm and 160 nm.
- the resulting film thickness depends on a large number of parameters, some of which are mentioned below. For example, play the attraction between Flusstechniksabstreifer and magnet, magnetizable body or counter magnet a role that determines the contact pressure of the wiper lip to the hollow chamber wall.
- the film thickness and the uniformity of the film depend on what friction, elasticity and conformability the wiper lip material has on the shape of the hollow profile. Furthermore, the film thickness is determined by the density of the felt used for the felt lip.
- the body of the liquid scraper is provided with rollers, then the distance between the body and the hollow chamber wall defined by the rollers and the maximum compression of the scraper lips defined thereby are of importance for the film thickness.
- the invention also relates to a Flusstechniksabstreifer, and an apparatus for removing excess coating agent. These are illustrated with reference to the drawings 1-4 in a particular embodiment, without the invention being limited to these.
- the Flusstechniksabstreifer shown in drawing 1 consists of a body (1) to which two magnets, counter magnets or magnetizable materials (2) in recesses (3) are attached. Likewise, at least one wiper lip (4) and a felt lip (5) is attached to the body. Rollers (6) are mounted on axles (7) in further recesses of the body.

Drawing 2 shows only one of the hollow chambers in longitudinal section with two remplissyersabstreifem arranged therein. Adjacent to the outer sides of the hollow profile strand or the hollow chamber are magnets, counter magnets or magnetizable body (11) attached to holding devices (12). Flusstechniksabstreifer, counter magnets, magnets or magnetizable body and holding devices are arranged in the rising portion of the hollow profile runway adjacent to the coating agent supply.
- a separating device not shown in drawing 2 for dividing the hollow profile strand is arranged in sections or hollow chamber plates desired length.
- Drawing 3 shows the cross section of the hollow profile, which is shown in drawing 2 in longitudinal section. It is a hollow chamber plate in which a hollow chamber (16) of two straps (17,18) and two webs (19,20) is limited.
- the two Flusstechniksabstreifer (10a, 10b) lie with their roles and lips only in each case only on one of the straps, as shown in drawing 2, and touch with their lips the belt and a portion of the webs.
- Drawing 4 shows in longitudinal section the Flusstechniksabstreifer (10b) according to drawing 1 and drawing 2, which rests with its rollers (6) and its lips (4,5) on the lower belt (18) of a hollow chamber.
- a hollow profile strand is extruded from the extrusion die at a speed of preferably between 0.2 and 5.0 m / min.
- the extruded from the nozzle strand is passed between the rollers (21) and (22) and then steered by means of elastic bending under the bottom roller (23).
- the strand is passed under elastic bending between the rollers (24) / (25) and (26) / (27).
- the strand is again passed under elastic bending between the rollers (28) and (29).
- the arrangement of the guide rollers results in a curved path of the strand.
- the roller (23) in the lower vertex of the path counteracts the elastic restoring force of the strand.
- the continuously advancing strand After exiting the extrusion die, the continuously advancing strand first passes through the supply of liquid coating agent in the valley of the arcuate pathway, thereby wetting the interior walls of the hollow chambers (16) with coating agent. Subsequently, the strand moves past the first diesstechniksabstsammlung (10a), which strip excess coating agent from the upper belt (17) and upper part of the webs (19,20) of each hollow chamber (16). As a result, stripped coating agent drips onto the lower belt of the hollow chambers and partially flows back into the coating agent supply. Excess coating agent, which does not flow off quickly enough and collect on the lower belt (18) and the lower part of the webs (19, 20), is then stripped off the second Flusstechniksabstreifer and can flow back into the supply.
