Description

METHOD FOR PREPARATION OF A REINFORCEMENT MATERIAL
The present invention relates to synthetic fiber-based reinforcement materials and a method for obtaining thereof.
Use of micro synthetic or macro synthetic fiber based reinforcement materials in composite structures is known in the industry. Such materials can be introduced into cement mixtures at reinforced concrete production. The synthetic fiber-based reinforcement materials are known to be produced and transferred in disposable packages, which are torn apart and disposed at releasing and introduction of the reinforcement material into the mixtures to be reinforced. Tearing apart of the packages can be considered as a process step corresponding to an operational cost. Additionally, disposal of the torn apart packaging material corresponds to a further transportation (waste removal) step and also a non-beneficial occupation of space. Primary object of the present invention is to overcome the abovementioned shortcomings of the prior art.
Another object of the present invention is provision of a method of introduction of macro synthetic or micro synthetic fiber based materials into aqueous mixtures, in high precision of dosage.
A further object of the present invention is provision of a product and method enabling and facilitating the introduction of reinforcement materials with minimized operational costs.
The present invention proposes a method for preparing a synthetic fiber based reinforcement material for use in concrete mixtures, comprising packaging of the reinforcement material in a packaging material which is dispersible in water. The present invention further proposes a synthetic fiber-based concrete reinforcement additive packed with packaging material which is dispersible in water. The packaging material can comprise a water-based paper.
In an aspect, the reinforcement material can be based on macro synthetic fibers. The relevant method can comprise the steps of separation of warps and wefts from a cord fabric by weft removal, bundling of the warps, wrapping of the bundles with a film comprising a water dissolvable polymeric material, slicing of the wrapped bundles, and packing of the slices into a packaging material which is dispersible in water. The water dissolvable polymeric material can comprise polyvinyl alcohol. The slices can be in form of cylinder with a length per diameter (L/D) ratio within the range between 0.25 and 5, or between 1.5 and 3.
In another aspect, the reinforcement material can be based on micro synthetic fibers. The relevant method can comprise the steps of drawing fiber yarns from separate coils together into a continuous longitudinal bundle, cutting the bundle into discontinuous bundles, and packing of the discontinuous bundles into a packaging material which is dispersible in water.
Accordingly, the present invention further proposes a synthetic fiber-based reinforcement material obtainable from such alternative methods.
The figures, whose brief explanation are herewith provided, is solely intended for providing a better understanding of the present invention and is as such not intended to define the scope of protection or the context in which said scope is to be interpreted in the absence of the description.
Figure 1 shows perspective view of an exemplary setup for producing macro synthetic fiber based reinforcement materials according to the present invention.
Figure 2 shows perspective view of an exemplary setup for producing micro synthetic fiber based reinforcement materials according to the present invention.
Referring now the figures outlined before, the present invention proposes a method for preparation of ready-to-use reinforcement materials comprising water-dispersible packages holding fiber-based material together whilst storing or transportation of the reinforcement material, to be employed in fiber reinforced concrete production. The packaging material can be a water-based paper, such that it is dispersible in aqueous cement mixtures upon a facilitated introduction of the reinforcement material thereinto. Any step of the process for preparation of the reinforcement can be easily integrated to automation.
The packaged product obtained with the method according to the present invention can be introduced into aqueous mixtures (e.g. aqueous cement mixtures in concrete production), without necessitating tearing apart the packaging material holding the synthetic fiber based materials together. Furthermore, any operational step(s) including removal of any waste based on such torn apart packaging materials is eliminated. Since no torn apart waste packaging material is emerged, any necessitation of respective waste collection and disposal space is eliminated, which further enhances the space usage in a respective workplace.
In an aspect according to the present invention, the reinforcement material comprises macro synthetic fibers. In this case, macro synthetic fibers can be easily introduced into aqueous mixtures (e.g. into cement mixtures at concrete preparation) in a water soluble package (or sacks), the package disperses in the aqueous mixture and the water soluble polymeric wrapping film is exposed to water resulting in dissolution of the film. As a result, the bundle of macro synthetic fibers are easily dispersed in the aqueous mixture, as well as a high precision dosing of the macro synthetic fibers into the aqueous mixture is enabled.
In an example according to said aspect, cord fabric in form of a roll (9) is subjected to weft removal in a weft removal unit (10), such that only warps of the cord fabric is separated from the wefts. The warps are then bundled and wrapped with a film comprising a water dissolvable polymeric material in form of a film, at a wrapping unit (20). The wrapping material can comprise e.g. polyvinyl alcohol (PVA) or another water soluble polymeric material. A longitudinal continuous bundle (e.g. with a mainly circular cross-section having a mean diameter of D, providing minimized use of wrapping material per each kg of fiber) can be obtained from the wrapping step. Then, the bundle is cut into slices (discontinuous bundles having certain lengths). Each slice having a length per mean diameter values (L/D ratios) preferably within the range between 0.25 and 5, more preferably between 1.5 and 3. Then, the slices are directed e.g. via conveyors (4, 5, 6) to a packaging step at a packaging machine (7) or a sacking step at a sacking machine (8). In packaging or sacking steps, the slices are packed into a packaging material which is dispersible in water. Sacking can also correspond to filling into big bags.
In another aspect according to the present invention, the reinforcement material comprises micro synthetic fibers. In this case, micro synthetic fibers can be easily introduced into aqueous mixtures (e.g. into cement mixtures at concrete preparation) in a water soluble package (or sacks), the package disperses in the aqueous mixture and the micro-synthetic fibers are released into the aqueous mixture. As a result, bundles of micro synthetic fibers are easily dispersed in the aqueous mixture, as well as a high precision dosing of the micro synthetic fibers into the aqueous mixture is enabled.
In an example according to said aspect, micro-synthetic fiber yarns from separate coils loaded into creels (11) are drawn together into a continuous longitudinal bundle at a drawing unit (21) and the bundle is directed to a cutting step at a cutting machine (3) to form discontinuous (i.e. cut) bundles of micro synthetic fibers. Then, the cut bundles are directed (e.g. via conveyors 4, 5, 6) into a packaging step at a packaging machine (7) or a sacking step at a sacking machine (8). Again, in packaging or sacking steps, the slices are packed into a packaging material which is dispersible in water.
Thus the following objects are achieved by the present invention:
- overcoming the abovementioned shortcomings of the prior art,
- provision of:
- a product enabling introduction of macro synthetic or micro synthetic fiber based materials into aqueous mixtures, with enhanced dosage precision,
- a product and method enabling and facilitating the introduction of reinforcement materials with minimized operational costs.
