EP2100816B1 - Transparent UV-resistant impact resistant cold-formable, thermoplastic container lining with roundings - Google Patents

Abstract

The container liner (1) consists of transparent, UV-constant, shock resistant polycarbonate. Cold-formed curve (4) and stability curve (5) are arranged at the container liner, where the curves are formed by considering maximum outer fiber strain at a ratio of wall thickness and bend radius with a factor greater than 100. The container liner is manufactured from a piece or individual added sections by Butt welding.

Description

The invention relates to the design of transparent, UV - resistant, impact - resistant and curve - shaped, cold - formable, thermoplastic container shells made of tabular starting material. These outer shells are exposed to direct UV light exposure as well as to the weather, or they require a transparent version for indoor use. They are impact-resistant, filled with liquid or bulk materials or flowed through, made of thermoplastic transparent materials. The connection of the same or different semi-finished products used between the container shell and the bottom and lid are realized by non-positive connections or by welding and adhesive seams.

Widespread and in accordance with the state of the art, for example, plastic containers of sheet-like starting material in a round and angular construction for different purposes of use of thermoplastic materials such as, PVC; PP; HDPE; or PVDF sheet material or other weldable thermoplastic semi-finished as pig or adhesive construction. Operating conditions such as operating temperature, medium, its density and level, as well as static operating conditions play an important role in the selection of the container material and the choice of their design. Basically, the thermoplastic materials mentioned are mainly processed by hot gas, drawing, Fächel-, Heizelementstumpf-, extrusion welding or gluing in plastic container
Container types whose main components such as sheath and base are made of steel, stainless steel or plastic, for example, are not offered, unless only individual components such as covers, manholes, sight glasses, pipe penetrations or the like are integrated on the container in flange form.

In addition to the general operating conditions, the influence of sunlight and, above all, of UV radiation must be taken into account for the production of welded thermoplastic plastic containers, which are used outdoors as outdoor applications. Due to the properties of the thermoplastics, only black PE-HD is used, as it is the only UV-resistant thermoplastic, weldable plastic for such applications. Other UV-resistant plastics are, for example, thermosetting polyester, and epoxy resins,
which in turn are partly used with so-called inliners made of thermoplastic materials, but are not transparent.
In the DE 199 52 151 A1 For example, a method of manufacturing a cylindrical container made of thermoplastic material such as PET with glycol (PETG) or PET is described. In this case, plates made of these materials, which have the size of the container shell to be formed, bent and cold-formed at the abutting edge by welding or gluing to a cylinder and joining connected. The resulting from the cold-formed bending of the container wall voltage is largely reduced by a thermal treatment, the annealing. To stabilize the upper edge of the container either a lid is placed or a circumferential reinforcing profile attached. To improve the scratch resistance, a special coating is applied to the surface.
Such containers can be manufactured due to the resulting material tension during cold forming only with very large radii, which in turn makes the arrangement of circumferential reinforcing profiles absolutely necessary. Above all, however, transparent thermoplastic and weldable materials such as PVC glass and normal PETG are not suitable for outdoor use. Their strength properties would deteriorate under UV irradiation in such a way that the stability of a container made of these materials could not be guaranteed in the long run. With the exception of PETG, which is only partially impact-resistant and cold-formable, there is still a very low impact strength in PVC glass, especially at low temperatures below 10 ° C.
In various applications, where not the medium,
but only the UV resistance of a container plays a role, the material acrylic glass is chosen because it is UV-resistant. He is indeed good adhesive. The disadvantage here, however, is that it is only partially weldable and only thermally deformable. Its applications in container construction are therefore very limited, or the manufacturability of complicated shapes and components is associated with a very high production cost.
At the same time, the strength of the material when used in low temperature ranges due to the brittleness and impact sensitivity, as in PVC glass is very low.

If transparent areas are to be realized on containers made of nontransparent material, this can only be achieved by the use of, for example, sightglasses or other visual elements, which in turn can only be integrated into the container construction by mechanically fastened designs in the form of flange fastening. As a result, only small transparent areas on a container, due to the size of flange connections can be realized.
Another reason for this is that only components made of the same material can be welded together.

This is precisely the reason for the fact that container bottoms and coats are always made of only one type of material in order to realize the connection between the bottom and the jacket in the welding or gluing process in a media-tight manner. Different types of thermoplastic materials can only be conditionally welded or glued. This in turn leaves only compromises on the strength of a container.
Geometric basic shapes in thermoplastic welded or glued containers are circular and square shapes. In which the container casing bluntly placed on the container bottom and the lid, the bottom or lid inserted flush with the container shell and these are connected by welding or gluing together.
Round, cylindrical designs of container jackets are when using PP; PE; PVDF and other semi-crystalline materials in semi-finished form of sheet material freely bent by cold forming and produced by butt or other welding processes as a cylinder. When using amorphous thermoplastic sheet semifinished products such as PVC and PMMA, the forming must be carried out by thermoforming and thus requires the use of large-area heating elements or radiators and forming aids, which must be matched to the respective mold geometry. Square designs of Behältermnänteln be welded or glued in the corners, in part, the corners are prefabricated by thermoforming, Abkantschweißen or the like and joined the connection of the individual shell parts in the straight outer surfaces by welding or gluing.

The stability of the straight lateral surfaces against deflection is achieved by suitable stabilizing elements such as steel frames or other load-bearing elements. However, this is very costly and expensive, but can only be so or by the choice of a disproportionately strong wall of the container shell realize an unreinforced or not properly sized rectangular container shell could be so deformed by the load of the medium in it or break.

In practice, for example, transparent, UV-resistant and impact-resistant containers are needed, which are either outdoors, in the outdoor use under the influence of the weather or in buildings and the container shell due to the use of the container must be transparent or should.

This applies, for example, to biological water treatment plants and waste-air treatment plants in which light incidence on the carrier material bed is desired in order to allow algae to grow in addition to the biological processes in them to photosynthesize the nutrients influencing the water to be treated, or to monitor the processes inside the plants can.
These water treatment plants are used, among other things, for the chemical-free, biological treatment of waters in transparent aquariums, swimming pools or fish tanks which are to be installed above ground and viewed from outside.

The invention is therefore based on the object to provide a technical solution, with the help of which, on the one hand, the deficiencies of the known state of the art can be overcome. On the other hand, the creation of a container casing should be made possible in which the production of freely selectable basic shapes, sizes and designs should be flexible and cost-effective, where it should be largely transparent, influences of UV radiation; Temperature; Weathering and knocks do not affect the tank shell should not adversely affect. In particular, a very flexible, cost-effective, stable and variable solution for the production of container coats is to be created, which allows the use of a UV-resistant transparent thermoplastic and impact-resistant plastic.

According to the invention, the object is essentially achieved by the characterizing features of claim 1. The advantageous embodiments are described in the subclaims.

Cold-formed curves are arranged on the jacket element of a container consisting of thermoplastic, transparent, impact-resistant and UV-resistant polycarbonate or UV-resistant PETG material, which, taking into account the maximum marginal fiber strain in the ratio of wall thickness S and bending radius r with the factor> 100 are formed.

The container shell is made of one piece or it consists of individual joined sections that determine its length and height. The shape of the curves of the container shell can be realized by form-compelling contours on the ground and on the edge cover or the lid of the container.

The statics and tightness of the container is achieved by the combination of container shell, bottom, edge cover and / or cover using connecting and sealing elements as well as using welding or adhesive seams. If no lid but only an edge cover is used for an open-topped container, the design of the width, thickness and reinforcement of the edge cover is dimensioned so that it prevents a deformation of the container edge> 2% to the width and length of a container. For high containers, the stability of the container shell supporting and formverfolgende the container shell outside circumferentially arranged reinforcing elements are attached, which serve as a wall reinforcement.
On the open market, various thermoplastic, transparent, UV-resistant sheet materials are offered, under which only polycarbonate and UV-resistant PETG material are considered to be very break-resistant (impact-resistant) cold-formable and temperature-resistant between -100 and + 100 ° C and therefore for outdoor use are outstandingly suitable.
However, polycarbonate or UV-resistant PETG material has not yet been used as a container material in plastic container construction, but mainly in the construction sector and in advertising technology
and used in machinery and vehicle construction.
Since the task of producing container casings is based on a suitable transparent, UV-resistant, k-deformable and unbreakable thermoplastic material, the properties of polycarbonate and UV-resistant PETG material have been subjected to further investigations. It was found that both materials, contrary to previous assumptions and taking into account special measures, but are butt weldable and are therefore suitable as materials for container shells. Further investigations will follow in the near future for the application of other welding processes.
By the use of conventional connection methods according to the prior art, however, polycarbonate as well as UV-resistant PETG material can already be bonded to itself and to other materials mechanically or adhesively.

The use of polycarbonate and UV-resistant PETG material as container shell material for freestanding containers whose shape is freely selectable, is made possible by the relatively good cold workability of the material.
The geometric arrangement of cold-formed curves allows
so as to increase the rigidity of a container wall of polycarbonate and UV-resistant PETG material, if at the same time the contour-tracking curves are held in accordance contour guides produced and so a deformation of the container wall is positively prevented.
For this purpose, grooves are incorporated in the bottom, the lid or the edge cover of the container or attached formula elements mounted in or at which the formation of the container shell is fixed.
By connecting the container components container shell, bottom, cover or edge cover so creates a dimensionally stable, stiffer and dense, transparent, UV-resistant, impact-resistant thermoplastic container.
To prevent deformations that may occur due to the internal pressure of the introduced in the container filling medium according to its filling height, if necessary in the height between the bottom and the edge of the container shell form-equal, circumferential reinforcing elements are arranged. The number and height distribution of these elements corresponds to the static requirements of the container. The position fixation of the reinforcing elements is effected by suitable support elements, which are arranged between the container bottom and the reinforcing elements, even reaching to the cover or the edge cover.

The invention will be explained in more detail with reference to exemplary embodiments.

Embodiment 1

According to the FIGS. 1 and 2 was produced in a square shape of similar transparent, UV - resistant, impact - resistant, thermoplastic and round container for a biological water treatment plant. All roundings 4 of the container are 450 mm in radius,
the square measure is 1400 mm, the height 1000 mm. It has a total volume of about 1890 liters, is up to a filling height of about 800 mm with glass foam gravel, which has a density of about 150 kg / m3, filled and is continuously flowed through with water, without the water is accumulated. Since the density of the filling medium is far below the assumed density of water, the wall thickness of the container shell 1 to be produced from polycarbonate was chosen to be 3 mm and the bending radius of 450 was now based on the calculation basis:
r = S x 150 (S = 3 mm, factor 150). In compliance with the maximum allowable marginal fiber strain on the container casing 1 with a factor of 150 x S and for optimal utilization of the semifinished product dimensions of the required plates for the container, the container dimensions was determined.
Made of commercially available transparent, UV-resistant polycarbonate panels
with the dimensions 3050 x 2050 x 3 mm were now the blanks of the stretched length of the container casing 1, resulting from the neutral fiber of the container casing 1 plus processing-related measurements, and the height of the container shell manufactured, the parts were drawing technology in preparation for production created a CAD program and thus determines the necessary dimensions for production.
The bottom 2, as well as the closed lid 3 of the container to be manufactured consists of UV resistant black PE-HD board material with a thickness of 15 mm, both parts are made of a commercial PE-HD board with the dimensions 3000 x 1500 x 15 mm by CNC - Milling made. In this case, the outer contours, the contour grooves 6 for receiving the container shell contour, as well as all for the fixation of the seals 7, the support elements 8 and the fasteners 9 of the container parts required bores 10 and openings 11 are made. After cutting the individual parts of the container shell 1 were now joined together by means of Heizelementstumpfschweißen so that a self-contained container shell 1 was created.
In the contour grooves 6 of the bottom 2 was now the seals 7, which consist of foam rubber profile with a diameter of 4 mm inserted and glued their butt joint tight by means of a suitable adhesive.

Subsequently, the container casing 1 was then introduced into the contour groove 6 forming its shape in the bottom 2. Because the curves 4 as well
the stabilizing curves 5 for shaping the container casing 1 allow cold forming of the polycarbonate used without material overstretching, the container casing 1 can be very well inserted into the contour grooves 6 and fix. Thereafter, in the contour groove 6 of the lid 3 is also a seal 7, as inserted in the bottom 2 and glued her shock. Now, the lid 3 can be plugged onto the container shell 1, wherein this continues at a position starting with the contour groove 6 continues to snap into their shape until both parts are finally held positively.
For stiff and tight connection of the items of the container so already joined are now only the support elements 8, which consist of commercial PE-HD hollow bar with a diameter of 50 mm and arranged between the bottom 2 and the lid 3 at the location of the holes 10 are to be clamped with the fasteners 9, which consist of commercially available stainless steel threaded rod M 12 and U-washer and nut.
In the openings 11 of the container produced as described can now be mounted according to required nozzles and connections, and follow the filling with glass foam gravel.
After transporting the container to the point of use and setting it up in the open area, the connection of appropriate pipelines, the commissioning of the water treatment plant in which the container is integrated as a main component can be done.

Embodiment 2:

In Application 2, an elongated transparent, UV-resistant, impact-resistant, thermoplastic swimming pool for above-ground outdoor installation was designed according to Figures 3 - 4.1 produced.
It has the dimensions: length 2900 mm, width 1400 mm and height 1000 mm and is filled up to 900 mm filling height with water. The material used is UV-resistant PETG plate material. The manufacturing steps are identical to those described in the embodiment 1. Only the shapes and sizes of the containers are different, the number and arrangement of the support elements 8, the holes 10, the fasteners 9 and the openings 11, and an open-top edge cover 13 in place Lid 3 and a central between this and the bottom 2 arranged circumferential stiffening element 12 distinguish both containers.
Since the transparent swimming pool during its use is exposed to varying loads and thus placed higher demands on the rigidity and stability of the container, to solve this requirement, the fasteners 9 were supplemented by attachment points 14, which in this case with Einschlagdübeln in the under the pool existing, consisting of concrete footprint were introduced. Thus, a firm clamping of the container from the upper edge cover 13, starting on the container casing 1 by the circumferential stiffening element 12 and the bottom 2 can be realized via the fastening elements 9 at the attachment points 14 and thus to the footprint.

Embodiment 3

In application case 3, an oval transparent, UV-resistant, impact-resistant, thermoplastic fish tank was also made of UV-resistant PETG material for above-ground installation in open terrain in accordance with the Fig. 5 - 6.1 produced. Its dimensions are: length 3000 mm, width 1000 mm, height 800 mm. It is filled up to 700 mm filling level with water in which fish are used. The fish tank should be visible from all sides and visible as a freestanding aquarium, which also
is connected to the described in use case 1 biological water treatment plant.
Since the place of installation is the container on a, accessible only through a narrow door, with the dimensions W x H 650 x 1900 mm available location, this is the problem to be solved that the container to be erected is to install only in place and a prefabricated complete container can not be spent there. Thus, the additional object is to provide the container casing 1 in parts, which can be introduced through the narrow door and mount the container in parts on site.
This object has been achieved by prefabricating the stretched length of the container shell 1 in two partial lengths as individual flat panels. These panels overlap during assembly at the butt joint and are by means of holes 10 and by means of fastening elements 9, which are arranged respectively inside and outside of the container casing 1 sealing elements 16, in which are inserted in contour grooves 6 seals 7 and where reinforcing elements 17 are arranged firmly and tightly connected.
The bottom 2, and the edge cover 13 should be designed very decorative in this case. To solve this problem was chosen as the material Corean for these two aforementioned components.
Corean is a very decorative mixed material made of PMMA filled with stone powder, which is very expensive. To save costs, therefore, only 6 mm thick panels for the bottom 2 and the edge cover 13 were used. Since in this, thin wall thickness no contour grooves 6 can be introduced, were to realize the receiving contour formation of the container shell 1 on the bottom 2 and under the edge cover 13 inside and outside the position of the container shell 1 on the ground 2 form elements 15 with a thickness of 12 mm arranged. The inner mold elements 15 were glued tight and the outer mold elements 15 were screwed. In the resulting intermediate space of the form elements 15, which corresponds in its cross section to the dimension of the contour groove 6, so again the seal 7 could be introduced, the shock was also glued tight. The further assembly of the container and its anchoring with the footprint was performed as shown in Example 2, except that no circumferential stiffening element 12 was needed.

Embodiment 4

According to the FIGS. 7 and 7.1 is to be integrated into a cylindrical thermoplastic round container with the dimensions D x H = 950 x 2000 mm, a transparent container segment through which the processes located therein are the carrier bed of an exhaust air treatment plant to be observed.
The lower container part 19, which is dammed with water, consists of welded black HDPE, its round cylindrical container casing with the dimensions D x H 950 x 1000 mm, a welded bottom with 10 mm thickness, and a patch welded edge 18 of 20 mm thick PE-HD, with a ring width of 80 mm. In the surface of the edge 18 was again milled, as usual in the bottom 2, a contour groove 6, in which later the transparent container shell 1 consisting of polycarbonate is inserted and fixed.
The container top 20 has the dimensions D x H = 950 x 500 mm, is also made of black PH-HD, has a cylindrical container shell, a bottom welded-edge 18 with a milled-on its lower surface contour groove 6 and a top-mounted, welded cone cover with middle manhole. The transparent shell segment of transparent polycarbonate to be realized between the container lower part 19 and the container upper part 20 was calculated and produced as a container jacket 1 with the dimensions D x H xs = 950 × 1000 × 3 mm as a round cylinder and its butt joined by butt welding.
In the contour grooves 6 of the edges 18 were again seals 7, the joints are glued inserted. The transparent container shell 1 was then inserted as a straight cylinder in the contour groove 6 of the upper edge 18 on the container base 19. Thereafter, the container upper part 20 was placed with the contour groove 6 at its lower edge 18 on the container shell 1 and fixed so all 3 container segments.
In the further sequence, a solid and tight bond between the 3 container segments were then prepared by the assembly of the support elements 8 and the fasteners 9, which are guided through the holes 10. Thus, the task was accomplished to equip a cylindrical thermoplastic plastic round container made of black PE-HD with a transparent jacket segment made of polycarbonate and so to be able to view its inside located carrier material bed circumferentially.

The described in the embodiments 1 to 4 containers are components of new innovative generations of biological water treatment plants for water pollution control without chemical agents in conjunction with freestanding visually very good-looking swimming or fish tanks and similar filled or trickling containers in the application of biofilms in the biological Exhaust gas treatment without the use of thermoplastic, UV-resistant, cold-formable, transparent and impact-resistant polycarbonate or UV-resistant PETG material or only with a much higher expenditure
on material costs, production costs and expenses, but then only with compromise feasible Währe.
By applying the invention, inexpensive, in any desired and curves having shape, transparent, UV-resistant, impact-resistant thermoplastic container coats can be offered and manufactured. These container shells produced in accordance with the invention offer significant advantages over conventional container shells for round or rectangular containers made of thermoplastic materials.

In addition to the very cost-effective production method and the UV resistance as well as the impact resistance, transparent container shells can be offered in any desired shape between round and square and thus compromises between the two types.
The technical development of polycarbonate and PTEG material as a UV-resistant material and corresponding welding process offers the possibility that the joining between the individual container components, if they are all made of polycarbonate or UV-resistant PETG material or with these weldable materials, instead of mechanical or adhesive connections can also be connected by welding technology.
