Abstract
This invention concerns an economical way to use shives, previously considered to be waste material, in the production of building materials. To that effect, shives of bast fiber or plant origin are targetedly added to bast fiber and a bonding agent. The shives can contain fibers which are not completely released and remain naturally attached. These fibers project laterally from the shives in an irregular fashion and are between 2 mm and 100 mm long. The shives and the loose fibers and/or the shives with the non-completely released fibers are fed, after corresponding dispersion and dosage, into a coating device for liquid additives and/or into a scatter system for solid additives, and subsequently evacuated as fleece or cake, during which mechanical matting can be performed by air flow.
Description
Technical field
The present invention relates to be used to produce material, method and the device thereof of building materials, what its Building Material House adopted is a kind of raw material with bast fiber (Bastfasern) and adhesive.
Background technology
The building materials that also add natural fiber material on the raw material of artificial synthetic and inorganic matter or half-finished basis were already through being familiar with by everybody.For example, the liner that is used for the automobile door is exactly this material.Both can be thermosetting plastics as matrix, also can be based upon on the basis of thermoplastic, produced the reliable drip molding that has glass fibre, bast fiber and sisal things such as (Sisal) thus.For weight reduction, matrix also will be sent very macrofoam.For this reason, the fiber that is adopted should have bast fiber, does not have fully or is not with shive basically.If when flax and oil flax, can allow that then contained shive composition is higher than the situation when using hemp and jute.Because the former cellulosic is thinner.
The wooden flakes of bast fiber plant also can be considered shive.These shives are formed when bast fiber is separated in by the core that contains wood fibre.Therefore, be transported to whole or the straw of cutting into chunks in the corresponding device thereof.This device makes the difficult wooden core of doing be broken into fragment, and bast fiber is separated from wooden.By " vibration ", perhaps, " mixed and disorderly fiber cutting streamline " by being made up of machine, be used for the remaining shive of cutting fibre just can produce the long fibre that does not almost have oil flax then, perhaps has the fleeces of certain remaining shive composition.
According to the structure of production equipment, can obtain short fiber as byproduct, it has higher oil flax bits composition and the less oil flax of relative fibre-bearing.The length of short fiber will be separated from remaining shive in next step operation between the 2-3 millimeter, and paper industry, the particularly industry of tobacco paper are given in main supply and marketing.There is not the oil flax of fiber just to let them go as far as possible to those.These oil flaxs are almost useless now, and maintain the place as refuse.According to latest find, on these places, removed wooden.
In decades morning, these bast fiber fibre of plant mainly are used in textile industry of making clothes and the textile of using as engineering (sail, hawser, canvas roof and tent etc.).Replaced by artificial synthetic fibers to a great extent during this period.Along with the reinforcement of people to the ecological awareness, worldwide people turn back again again, seek a kind of bast fiber material.Be used for the car inner structure and, manifested the use emphasis in this field as the non-textile used of insulating materials of building.
Slough wooden after, fiber also must be through multiple tracks cleaning of taking a lot of work consuming time and incision process.By these operations, fiber also just has been shortened inevitably, and becoming has elasticity and softness.But the non-woven fabric of being made up of flexible fibre itself can not be tall and straight.Because they are too dense, are soaked into owing to thermoplastic fusing, thereby become heavy and do not have rule.This situation also appears at by artificial synthetic, or on the spraying coating or injection moulding coating of the thermosetting plastics that constitutes by biological species.Since can not be tall and straight, with regard to the non-textile that is used to insulate, the insulation that has also just partly lost it is worth.Therefore, must carry out chemical combination to staple fibre, the fragility by artificial synthetic fibers stops the softening of material.
Say that in principle shive also all is a little extremely light wooden, it is light little of almost with western India cork wood (BalsaHolz).Not only firmly but also crisp and band fibre structure, density range was at 250-350kg/m for they
3Between, the ratio of its rugosity coefficient is not very big after the fracture.Opposite with shive, the fiber by the bast fiber plant generates also has short fiber, has the ratio of higher intensity and rugosity coefficient.According to technical merit, bast fiber and shive finally separate always, because, the shive of further process, can be used for making textile, straw mattress and spheroid goods etc. such as the interference of employed machine of known product and technology generation now to current, and major part is difficult to accomplish even do not process.

The specific embodiment
As shown in Figure 1, if most of fiber all breaks away from shive, the fiber 19 that then stays has been a sub-fraction only.According to application target, its fibre length is 5-100mm.The side that does not break away from the fiber 19 of shive fully is that assorted gift does not have thread.By adequate measures, for example, compression or friction, purpose is reinforcing fibre 19 structural confusions.According to decomposing classification, its bulk density is at 90-120kg/m by the shive 18 that clears in the short fiber
3, bulk density can drop to 15kg/m as long as partly remove when wooden then
3Because of the longitudinal axis of nature is arranged, so great majority are in and are arranged in parallel by the shive that cleans out in the fiber.If shive and fiber are mixed, then numerous fibers is to be in direction-freely on sizable degree, that is to say, is in a kind of isotropic state.When fiber 19 not fully when shive 18 breaks away from, by shown in Figure 2, produce very big cavity in the middle of chaotic structure makes.Numerous interface points between shive 18 and bast fiber 19 and intersected to form natural polymerization place, wooden at this position because of not sloughing fully, well imagine it is can not eliminate woodenly to combine with fiber.
According to shown in Figure 3, above one case reservoir 2, the mechanical feed conveyor belt 1 of a circulation is arranged, this conveyer belt 1 hunting range equals the whole width district of case reservoir 2.The case reservoir is set up a slip scraper plate 2.1 that has broach as the bed depth eliminator.The floor conveyor 3 that has the bulk cargo scraper plate passes through below case reservoir 2.The feeding amount of this conveyer belt is adjustable.Limited by slip scraper plate 2.1 bed depths, so, just be cut off through floor conveyor 3 bed of materials that have the bulk cargo scraper plate.The metering of quantity surpasses feeding speed.In order further to solve quantitative feed and the energy accurate feeding on enough height, be provided with a tilting conveyer belt 4 that has the bulk cargo scraper plate.The adjustable distance of tilting conveyer belt 4 is the rollers 5 that move back to rotatable band needle roller shape.For making material on the tilting conveyer belt 4 take off material and comb falls, be provided with a roller 6 that takes off the band needle roller shape of material usefulness.The rotating speed of this roller 6 is adjustable, therefore, except taking off material and comb fall of material, also can influence the shredding rate.
Cleaning roller 7 is the band needle roller shape rollers 6 that take off material usefulness in order to cleaning, and this roller is brush or fan-type.The roller 5 of tilting conveyer belt 4, swinging band needle roller shape, the needle roller shape roller 6 that takes off material usefulness and cleaning roller 7 can be linked to be each each other and transmit unit.When being connected on last unit, be provided with a decomposition-bulk cargo head-combined unit 8.The mixed conveyer belt 9 of raw material that is fallen by tilting conveyer belt 4 receives.On conveyer belt 9, form loose fiber attitude 17, before this, send into liquid additive, and/or add the solid material by a bulk cargo system 11 by a nozzle system 10.When needing, can arrange more hybrid conveyor 9.Each hybrid conveyor 9 all is provided with one takes off material and mixes the needle roller shape roller 12 of usefulness.This roller 12 can be designed to be with pin bar, brush or fan-type roller.By roller 12, layer multilayer or few, be positioned at the roller that has additive and close material on the conveyer belt 9 and just fallen and roll, so that level is loosened and homogenising by comb.Then, material through conveyer belt 13 be transported to one basically with a tilting conveyer belt 4, roller 5-7 and loosen-unit that bulk cargo head-combined unit 8 is identical.Because shive 18 and fiber 19 have reached sufficient mixing by additive, so far material is finally scattered and is become fibrously, also can place container or mould to material.
If one forms chaotic fibr tissue, perhaps want to improve the fleece of chaotic structure, can be with blow pressure on 14 to material toward sieve by air-flow 15.Vacuum tank 16 is used for producing air-flow 15, and this case is positioned at the sieve that receives material with 14 below.Air velocity is between the 2-20 meter per second, and microbit can not accomplish to be arranged in parallel under this speed, but alternating expression, and fiber is sorted in no direction.Like this, also just constituted a kind of unordered fleece.
