Definitions
- the invention relates to a multi-chamber foil bag for a multi-component inorganic foam system and to the use of the multi-compartment foil bag for packaging and / or processing of a multi-component inorganic foam system. Furthermore, the invention relates to the use of the multi-chamber foil bag in a process for producing a local foam, in particular an inorganic fire-resistant foam.
- a reactive material of two components is mixed on site and introduced into the opening.
- the reactive material should be stable until cured, so that it does not flow out of the opening again.
- two-component liquid resins such as polyurethane or epoxy resins
- the stability is achieved by a corresponding adjustment of the viscosity of the material.
- the reactive components are presented separately in two-component cartridges and mixed with a static mixer.
- static mixers are not suitable for mixtures of powder components and liquids, because bridge formation occurs in the powder component, which prevents mixing in the static mixer by pressure. From powder and liquid existing masses are therefore mechanically mixed together in an open vessel with the help of stirring rods or other mixing aids.
- the mixed mass can then be manually introduced into the opening to be filled and / or brought into the desired shape, or filled in other application aids such as dough presses and introduced into the opening.
- the powder is to be mixed in a closed container with the liquid, further aids such as balls are needed in a partially filled with air space. To empty the container, a substantially liquid consistency of the mixture is required.
- liquid two-component casting resins which are introduced into a two-chamber foil bag with clamp closure.
- the potting resin is mixed by hand after removing the clamp closure and then poured, for example, in cable lugs.
- Multicomponent systems for producing gypsum foams and / or cement foams by mixing in open vessels are known, for example, from EP 2 045 227 A.
- This document describes a hydraulically setting composition for the production of inorganic fire-resistant or insulating local foams with a pH-neutral or alkaline hydraulic binder and a foaming component and a foam stabilizer, wherein the foaming component releases oxygen or carbon dioxide.
- the known inorganic fire protection systems are difficult to introduce into openings and are often applicable only as a potting compound with elaborate formwork devices.
- a simple and inexpensive packaging for quickly mixing the powdery and liquid components for an inorganic foam based on gypsum or mortar in a closed container is not known. Therefore, such inorganic foam systems, despite a relatively low price of materials, have not been customary in the marketplace.
- the invention has for its object to provide a simple, user-friendly and cost-effective application form and packaging for rapid mixing of powder and liquids in a closed container, in particular for an inorganic foam based on gypsum or mortars for fire protection applications.
- the application form should allow the mixing of the components without expensive tools and allow the introduction of the foam system in tight and / or difficult to access openings.
- a multi-chamber foil bag according to claim 1 This object is achieved by a multi-chamber foil bag according to claim 1.
- the invention further provides the use of the multi-chamber foil bag according to claim 10 for packaging and / or processing of an inorganic multi-component foam system, and a method for producing a local foam of an inorganic multi-component Foam system using the multi-chamber foil bag according to the invention with the features of claim 1 1.
- the invention provides a multi-chamber foil pouch for a multi-component inorganic foam system comprising at least two fluid-tight chambers, one of the compartments having a powdery inorganic component, optionally based on gypsum or cement mortar, and another chamber having one, optionally for the inorganic component of the reactive powdery foaming component is filled, and having a separating member which liquid-tightly separates the chambers in a first state and can provide flow communication between the chambers in a second state, at least one of the chambers having an opening portion for discharging the foam system can be opened, and wherein the opening portion having the chamber has a preset residual volume for receiving a liquid.
- the multi-chamber foil pouch according to the invention makes it possible to provide a foil pack with fixed quantities of reactive components for the powdery inorganic foam system, predetermined by the pack. Thus, a misdosing by the user can be safely avoided and the mixture is ready for immediate use. It is particularly advantageous that a liquid necessary for the production of the foam, usually water, is introduced into the foil bag only when in use on site and thus the transport weight and transport volume are saved. Due to the specified filling volume, accurate metering of the liquid without measuring instruments is possible.
- the separating element of the multi-chamber foil bag can be easily opened without tools. By simply kneading the components, good mixing results can be achieved. To discharge the foam system no mixing and Auspresswerkmaschinemaschinee are needed. Nevertheless, it remains possible to use the film bag according to the invention for discharging residual amounts with a known film dispenser for one-component masses.
- the opening section for discharging the foam system provided in at least one of the chambers can be designed as a tapered outlet, for example as a nozzle tip, and thus enable a metering of the foam system into narrow and difficult-to-access openings. Furthermore, after the components have been mixed in the film bag, the foam system can already be in a firm pasty consistency in order to prevent the mass from flowing out of the openings to be filled.
- the invention further provides a cost-effective and space-saving film packaging. During the mixing of the optionally reactive components in the film bag, dust formation from the powdery component can not occur. A contact of the user with the reactive foam components during mixing is excluded, so that a health hazard is avoided by reactive components.
- the multicomponent foam system is a two-component foam system of an inorganic fire-resistant foam or insulating foam with at least one hydraulic binder, at least one foaming system and optionally a foam stabilizer.
- Cement in particular Portland cement, trass, pozzolans, hydraulic limestones and gypsum or mixtures thereof can be used as the hydraulic binder.
- the foaming system can be formed, for example, from an alkali or alkaline earth carbonate or bicarbonate as a powder component and a powdery acid as a foaming component.
- a powdery acid is meant a chemical compound which causes an acidic reaction when dissolved in water, for example, citric acid or water-soluble salts of a weak base and a strong acid.
- the foaming system may alternatively or additionally comprise an oxidizer and a catalyst.
- the oxygen carrier of the foaming component may be pulverulent peroxides or percarbonates, in particular sodium percarbonate. Powdery compounds suitable for the catalytic decomposition of percarbonates, for example in the form of metal salts, are known.
- the catalyst may comprise manganese dioxide manganese MnÜ2 in powder form.
- At least one of the chambers of the multi-chamber film bag according to the invention has an opening portion which can be opened to fill the chamber with a liquid and then discharge the foam system.
- the chamber having the opening section has a preset residual volume for receiving the liquid, so that the inorganic powdery component, the foaming component and the liquid after mixing give a ready-to-use foam.
- the liquid is water.
- residual volume is meant the volume of the chamber remaining after filling one of the components in the chamber having the opening portion.
- the presetting can take place by virtue of the fact that the volume of the chamber remaining after the powder component has been filled corresponds exactly to the quantity of liquid required to produce a ready-to-use foam.
- the default can also be done by a mark provided on the chamber. In this case, the chamber is not completely filled even after filling the liquid. In both cases, however, the liquid can be precisely metered without additional measuring instruments.
- the foaming component is present in the chamber having the opening portion.
- the separating element may be formed as a peel seam or as a clamping element.
- the peel seam may be effected by heat-sealing or welding the opposing foil walls of the foil bag in an edge region of a chamber, so that this chamber is separated from the adjacent chamber of the foil bag in a liquid-tight manner.
- the tear strength of the peel seam can be adjusted such that the peel seam is torn open by pressure on one of the chambers and a flow connection between the chambers is provided.
- the separating element may be formed as a clamping seam.
- the clamping seam can be formed in the manner of a lip closure pocket or zipper connection with two interlocking clamping strips.
- a clamping rail to the film bag from the outside

- the clamping rail and / or the clamping strip is already attached to the outer wall of the film bag, for example by gluing or welding.
- the separating element can be provided with compulsory mixing compounds which enable a faster and more homogeneous mixing of the inorganic powder component with the foaming component dissolved in the liquid during use.
- compulsory mixing compounds which enable a faster and more homogeneous mixing of the inorganic powder component with the foaming component dissolved in the liquid during use.
- fixed webs may be provided between the opposing films of the film bag in the region of the separating element, or weld seams may be provided which remain in the pressure on one of the chambers and do not tear open.
- the multi-chamber film bag can be formed as a stand-up pouch, as a flat bag or as a tubular bag.
- Stand-up pouches are usually equipped with a W-fold in the bottom area, which expands when filling the chamber in the bottom area and ensures a firm footing of the foil pouch.
- Flat bags are usually formed by stacking two plastic films and randum Anlagendes welding of the films.
- Hose bags are formed by spraying the plastic films from round nozzles to form a film tube and bottom-side welding of the hose ends or jamming of the hose ends with a metal or plastic strap.
- the multi-chamber film bag is designed as a flat bag with edge-circumferential weld.
- the opening section for discharging the foam system is provided with a screw-in closure welded into the foil bag.
