Definitions
- the invention relates to a building material using bast fibers and a binder as well as a method and an apparatus for producing this building material.
- thermosets and thermoplastics as a matrix molded parts that are made with glass fibers, bast fibers, sisal and. a. are reinforced, the matrix to reduce the weight is still foamed in many cases.
- fibers from bast fiber plants are found
- cockroach-free Use that are completely or predominantly cockroach-free, whereby a higher cockroach percentage 1 can be tolerated for flax and oil-flax than for hemp and jute, since they are finer.
- the wood fragments of bast fiber that are created when the bast fibers are separated from the woody core are called cockroaches.
- the stalks are fed in full length or in appropriate stalk sections, which break the brittle wood core into fragments and thereby detach the bast fiber from the wood.
- By “swinging” or “tangled fiber lines” with subsequent machines for cutting off residual cockroaches from the fibers either an almost cockroach-free long fiber or a tow with a certain residual cockroach fraction 1 is then produced.
- short fibers with a higher proportion of cockroaches and relatively low-fiber cockroaches are produced as a by-product.
- the short fibers between two and thirty millimeters in length are freed of the remaining cockroaches in further operations and are mainly sold to the paper industry, especially the cigarette paper industry.
- the largely fiber-free cockroaches must be disposed of. According to the latest developments, deforestation is already taking place on the field in order to leave the cockroaches, for which there is currently hardly any use, as waste on the field.
- bast fibers were mainly used for the production of clothing text I 1 len and technical textiles (Seh lffssege 1, ropes, tarpaulins, tents, etc.). They have now largely been replaced by synthetic fibers. With increasing ecology-conscious a comeback of bast fibers will be tried worldwide. The main areas of application are nonwovens for the manufacture of car interiors and for dam purposes in the building industry.
- cockroaches are extremely light wood, almost as light as balsa wood. They are stiff and brittle and have a fiber structure. Their density is in the range between 250 and 350 kg / m 3 . After breaking, they are not very high in sight.
- fibers made from bast fiber, including short fibers have a very high strength and a very high degree of slenderness. According to the state of the art, bast fibers and slivers are always separated thoroughly, as cockroaches are used for further processing operations on the machines and Technologies for the production of nonwovens, mats and balls as well as for spinning as well as for currently known products have a disruptive effect and for the most part even make processing impossible.
- the invention has for its object to economically use the cockroaches previously considered waste and to use them in the manufacture of building materials and components.
- This object is achieved according to the invention in that building materials are specifically mixed with bast fibers and a binding agent, and scrapes of bast fiber are mixed in a targeted manner.
- the fibers protrude laterally irregularly from the cockroaches.
- the cockroaches have lengths of between 2 and 50 mm and the fibers which are partially connected to the cockroaches 0 have lengths of between 2 and 100 mm and the loose fibers have lengths of between 2 and 80 mm.
- the fibers can have a crimped shape.
- the cockroaches and the loose fibers and / or the cockroaches with the incompletely dissolved fibers are loosened after appropriate loosening and dosing of an application device for fillings and / or a spreading system for solid additives and then sprinkled as a fleece or cake. It is possible to mechanically matt the cockroaches and fibers of the fleece or the cake by means of air flow.
- a box feeder is preceded by an upper circumferential mechanical feeder and a circulating floor conveyor with a scratch set for pre-metering, wherein the box feeder can be assigned a bed height limiter in the form of a slide with a comb.
- a steep conveyor with scraper and a wiping spike roller are arranged for fine and subsequent dosing.
- Figure 1 is a view of a cockroach with fibers not completely detached.
- Fig. 2 shows the principle of fleece formation from cockroaches according to Fig. 1 and
- Fig. 3 is a schematic representation of a device for producing the building material.
- the fibers 19 are only partially, if predominantly, detached from the cockroach 18.
- the fiber lengths are specifically in the range from 5 to 100 mm.
- the fibers 19 not completely detached from the cockroach 18 protrude laterally from one another.
- the tangled structure of the fiber 19 can be specifically reinforced.
- cockroaches 18 e cleaned from short fibers have debris weights between 90 and 120 kg / m 3 , depending on the type of dismantling, the debris density can be reduced to 15 kg / m 3 with only partial deforestation.
- Cockroaches cleaned of fibers lie largely parallel to each other due to their natural longitudinal axis. A mixture of cockroaches and fibers results in a fairly loose alignment, that is an isotropic arrangement. If fibers 19 are not completely detached from the cockroach 18, large gaps are formed according to FIG. 2 due to the tangled structure. There are a large number of points of contact and intersection between cockroaches 18 and fibers 19 in addition to the natural adhesions at the points where the bond between wood and bast fiber 19 was deliberately not broken due to incomplete deforestation.
- a mechanical feeder 1 is arranged in the form of a circulating belt via a box feeder 2.
- the feeder 1 oscillates across the full width of the box feeder 2.
- the box feeder 2 is a slider 2.1 with a comb assigned as a visual height limiter.
- Below the box feeder 2 runs a floor belt 3 with a scratch set.
- the feed of the floor belt 3 is infinitely adjustable. If the height of the layer is limited by the slider 2.1, then this layer is milled off by the base band 3 with a scratch set. The quantity is metered via the feed rate.
- a steep conveyor 4 with a scratch set is provided. At an adjustable distance from the steep conveyor 4 there is a backstroke f sting wa 1 ze 5.
- the speed of the stripping roller 6 can be regulated so that, in addition to stripping or combing the material, the degree of ocher can also be influenced.
- a cleaning roller 7 which can be designed as a spiked, brushed or shed roller, is used to clean the wiper roller 5. It is possible to switch several groups of steep conveyors 4, scraper sticks 1 rolls 5, scraper spiked rolls 5 and cleaning rolls 7 in more groups. Following the last group, a loose-streak head combination 8 is arranged. The material falling from the steep conveyor 4 is picked up by a Mi schf orderer 9. On this conveyor 9 there is a loose VI lesbi ldu ⁇ g 17, with 10 liquid additives and / - or a spreading system 11 solid additives having been applied beforehand via a nozzle system. If necessary, more than one Mi challenger 9 can be arranged. A scraper and mixing spike wa 1 ze 12 is assigned to each mixer 9.
- the roller 12 can also be designed as a spiked, brushed or shed roller.
- the roller 12 combs and swirls the more or less layer-by-layer material with additives onto the mixer 9 to dissolve the layers and homogenize them.
- the material is fed via a conveyor belt 13 to an aggregate group, which is largely identical to the steep conveyor 4, the rollers 5 to 7 and the Auflos-Streukopf-Kombi nat I on 8.
- the final scattering or fleece shaping 17 now takes place since the cockroaches 18 and fibers 19 are sufficiently mixed with the additives.
- the material can be printed on a screen belt 14 by an air flow 15.
- Vacuum boxes 16, which are arranged below the sieve belt 14 receiving the material, are used to generate the air flow 15.
- the air flow has a speed between 2 and 20 m / sec. At this speed, the particles do not line up in parallel, but shoot into one another and thereby achieve a fiber-free arrangement and thus form a random fiber fleece.
