Definitions
- the invention relates to a Einblasdämmstoff based on 100 percent cattail leaf fibers, and a suitable manufacturing method for this purpose.
- blow-in insulation materials are made of cellulose (waste paper), wood fibers, hemp fibers or other renewable raw materials. They all have fire safety equipment with boron salts or similar salts. They also have average thermal insulation properties (lambda approx. 0.04 W / mK). Wood fiber blow-in insulation materials, for example, can only be processed with special blow-in machines and can be difficult to compact in wall construction.
- the object of the invention is to provide an additive-free, machine-accessible and / or settling Einblasdämmstoffs based on cattail leaf fibers.
- Uncultivated cattail leaf mass is very light with about 60 kg / m 3 . This is mainly due to the fact that the plant consists of about 85 percent by volume of a light sponge fabric.
- the above-ground leaf mass of cattail consists essentially of sponge tissue and leaf tissue.
- the sponge tissue is essentially isotropic.
- the leaf tissue which is also referred to as "stem outer skin", holds the sponge fabric as a thin layer in intact cattail leaf and, like wood, has a unique fiber direction.
- the leaf tissue is therefore strongly anisotropic with respect to many material properties such as thermal conductivity.
- the Einblasdämmstoff invention consists of possibly only crushed cattail leaf fibers, ie, for example, chopped or ground leaf fibers, as defined in claim 1.
- Chopped cattail leaf fibers have a smooth surface. They are good machine-accessible. Since the individual fibers do not interlock with each other, they tend to settle.
- Ground cattail leaf fibers have a rough surface and interlock strongly with each other. As a result, they can be installed very sedentary. However, they can not be processed in standard injection-molding machines because they lead to blockages in the systems.
- the invention solves this problem by mixing smooth fibers and highly fibrillated material. It is also a uniform, moderate defibration of the cattail leaf mass possible.
- the degree of defibration is directly related to the flowability of the material. The stronger the cattail leaves are frayed, the less flowable the material is. For use as blow-in insulation, a balance must be established between processability (in which case the material must be free-flowing) and settlement safety (in this case it should have the lowest possible flowability).
- the Einblasdämmstoff invention consists of fibers of the above-ground leaf mass of cattail, and is characterized in that
- shredded cattail leaf fibers in at least two dimensions have a dimension lying in the range of 1.4 to 10 mm and
- shredded cattail leaf fibers having a dimension greater than 0 mm in at least two dimensions.
- the ranges are:
- the particular settlement safety of the Einblasdämmstoffes according to the invention is procedurally achieved in that are cut over the cutting technique of cattail leaf fibers leaves for the leaf mass in at least two different lengths, namely 30% to 70% in a first fiber fraction with about 10 to 100 mm and correspondingly 30% to 70% in a second fiber fraction of about 3 to 6 mm in length, preferably about 3 to 5 mm in length.
- the blow-in insulation according to the application is particularly well suited for thermal insulation, sound insulation or impact sound insulation or as an oil absorber.
- the Einblasdämmstoff shows a water absorption coefficient Wp is in the range between 1, 38 and 2.02 kg / m2 , preferably an average of 1.65 k9 / m 2 , which is to be marked as water-repellent.
- the blow-in insulation according to the invention can be processed with all current Einblasanlagen be well promoted by a flow of air and installed settling safe in a wall and roof structure.
- the material can be produced without additional fire-retardant (Euro Class E without additives) and achieves a low thermal conductivity (lambda 0.038 W / mK).
- the blow-in insulation according to the invention can be installed with a compression of 50 to 80 kg / m 3 .
- the settlement behavior is tested according to the following standard: ISO / CD 18393.
- the machinability of the blow-in insulation depends primarily on the fact that there must be no blockages in the machine. These can arise mainly in 2 places:
- blow-in insulation according to the invention is produced, for example, by
- Cattail leaf fibers are chopped to a length of 3 to 10 mm; or b) Cattail leaf fibers are shredded to a length of 10 to 100 mm and then minced or ground in a hammer mill, a pin mill, or a knife ring chipper and the chopped and chopped milled cattail leaf fibers in proportions of 30 to 70 weight percent, based on the total weight.
- the crushing of the chopped cattail leaves takes place in a hammer mill, the lateral surface of which comprises the drum has longitudinal slots of 3 to 5 mm width and 1 to 9 centimeters in length, the longitudinal direction of the slots being in the circumferential direction of the hammer mill.
- To produce the cattail leaf fibers used in the invention only very little energy is consumed. This is a technical advantage that also has an impact on the product price as energy prices rise. Wood fibers, which are also used in the prior art for blow-in insulation, consume 10x more energy for defibration.
- At least one substance selected from soda, ammonium sulfate, aluminum sulfate, aluminum phosphate, siloxanes and boron salt may be added to the shredded cattail leaf fibers to improve fire safety.
- a leaf bundle of dry cattails is cut transversely to the fiber direction of the leaf tissue to just under 1 cm long pieces and then further comminuted in a hammer mill.
- the hammer mill has a revolving in a drum anchor, which is provided at the periphery with projections - which are referred to as hammers.
- the lateral surface of the drum is provided with longitudinal slots of 4 times 80 mm in cross-sectional area, with the larger dimension in the circumferential direction.
- Messerwellenenzerspaners can also be machined by means of a so-called Messerwellenenzerspaners.
- an inner armature and an outer, provided with knives drum rotate coaxially in the opposite direction of rotation.
- the cattail leaf material to be cut is removed by blades of the outer drum in the gap between the two rotating bodies.
- the clippings fall through gaps in the outer drum to the outside.
- Good results are achieved with a knife shaft achieved in which the blades protrude inward a millimeter from the circumference of the outer drum surface and wherein the gap width for the passage of the cut material is 2.4 mm.
- the generated cattail particles are mixed together in a drum mixer.
- the mixing can be continuous or discontinuous. But there are also all other known mixing techniques possible.
- the cut particles are added to 30-70% of the mixture.
- the particles from the hammer mill or the knife shaft shredder are added to 30-70% of the mixture.
- the respective length specifications of the cut cattail leaf fibers may overlap in terms of percentages by weight, and shall be added up to 100 percent by weight each.
- the properties of the blown insulation according to the present invention are also not affected when the reported machined and mixed cattail leaf fibers are blended with cellulose blow-in insulation in the ratio of 0 to 95% by weight, preferably 30% by weight of cellulose blow-in insulation, i. corresponding to 70 weight percent cattail leaf fibers, in accordance with the method according to the application and mixing ratio prepared.
- the blow-in insulation from cattail leaf fibers (Typha) according to the invention can be used well for thermal insulation or thermal insulation.
- the blow-in insulation according to the invention is also suitable for sound insulation and impact sound insulation or as an oil absorber.
- it has a significantly lower water absorption during short immersion compared to cellulose (method A according to EN 1609).
- the average value of 4 tests was 1.65 ⁇ 0.27 kg / m 2 , which was significantly lower than that of the Comparable density cellulose fiber (65 kg / m 3 ) and 27.00 ⁇ 0.28 kg / m 2 .
