Definitions
- the present invention relates to a device for determining the fineness of mineral fibers, these fibers being intended in particular for the industrial manufacture of glass wool which must be used, for example, in the composition of thermal and / or acoustic insulation products. It also relates to a method for measuring the fineness of mineral fibers as well as the application of this device to the measurement of fineness of hyper-fine fibers.
- micronaire The measurement of the “micronaire” is known in this technical field to characterize the fineness index, this index accounting for the specific surface as a function of the measurement of the aerodynamic pressure drop when a given quantity of fibers, devoid of binder , is subjected to a given pressure of a gas - generally air or nitrogen.
- micronaire device On the basis of these teachings, a micronaire device has been developed and is commonly used, which indicates, from a device for measuring the fineness index of mineral fibers, graduated in “micronaire” value, reliable measurements for average fiber diameters of substantially between 3 and 9 ⁇ m and in this range of average diameter. This average diameter is calculated from the histogram measured under the microscope (x 1000) of 200 fibers.
- manufacturers in their constant search for improving the overall heat exchange coefficient and / or reducing the density of products for the same thermal capacity, are led to develop fibers (called hyper fibers fines in the rest of the text) whose mean diameter is constantly decreasing and tends to be included in the range 2 to 3 ⁇ m, or even much less.
- the present invention proposes to provide a micronaire device adapted to provide micronaire values for hyper fine fibers (whose average diameter is less than 3 ⁇ m).
- a device for determining the fineness index of fibers adapted to provide the micronaire value of mineral fibers whose average diameter is substantially greater than 3 ⁇ m comprising a device for measuring the fineness index, said device for measuring the fineness index being provided on the one hand, with at least a first orifice connected to a measuring cell suitable for receiving a sample made up of a plurality of fibers, and on the other hand, with a second connected orifice a device for measuring a differential pressure located on either side of said sample, said device for measuring differential pressure being intended to be connected to a device for producing fluid flow.
- a device for determining the fineness index of the genre in question is characterized in that the device for measuring the fineness index comprises at least one volumetric flow meter for the gas passing through said cell.
- a micronaire value is quickly obtained from a device for determining the traditional fineness index. hyper fine fibers, without having to modify its calibration and operating conditions (quantity of fibers introduced into the cell, value of the differential pressure, etc.).
- volumetric flow meter consists of a volumetric flow meter graduated in l / min;
- one of the orifices comprises a calibrated member;
- it also relates to a method for measuring the fineness of fibers using a device for determining the fineness of mineral fibers as referred to above, characterized in that:
- the measuring cell is filled with a sample of fibers, the mass of the sample being determined in such a way that the sample occupies the entire volume of said measuring cell, so that there is no flow preferential gas within the sample,
- the value of the differential pressure prevailing between the upstream and downstream of the sample is adjusted after closing said cell using a cover
- said measuring device is connected to a device for producing fluid flow
- the measurement is made using the volumetric flow meter.
- the entire volume of the measuring cell is filled with a sample of fibers whose mass is equal to at least 5 g, preferably between 5 to 10 g, and even more preferably equal to 5 g
- the invention also relates to the application of the measuring device described above for measuring the index fineness for hyper fine insulation fibers (average diameter less than 3 ⁇ m), in particular glass wool, in particular obtained by an internal centrifugation process.
- FIG. 1 is a schematic view of a "micronaire" apparatus according to the invention
- - Figure 2 gives for various densities of fibers, the value of the coefficient of thermal conductivity as a function of the micronaire value expressed in l / min.
- the same references designate identical or similar elements.
- FIG 1 there is shown a micronaire apparatus according to the invention.
- This device 1 comprises a measuring cell 2, preferably cylindrical.
- This cell 2 is adapted to receive a sample of fibers, for which the measurement of their fineness is sought.
- This device also includes a device 8 for measuring the fineness index.
- This device for measuring the fineness index 8 comprises at least a first orifice 3 connected via a first pipe 4 to the measurement cell 2 adapted to receive the sample made up of a plurality of fibers.
- This same device for measuring the fineness index 8 also includes a second orifice 6 connected via a second pipe 7 to a device 5 for measuring a differential pressure located on either side of said sample.
- This differential pressure measuring device 5 consists for example of a pressure regulator whose value is fixed and is kept constant at 254 mm Hg.
- the device 8 for measuring the index fineness consists of a transparent cylindrical tube of cross section circular, within which a mobile indicator (of the ludion type) can translate, this tube being graduated in “micronaire” value.
- the device 5 for measuring the differential pressure is connected by a third line 9 to a device 10 for producing a constant gas flow, and the gas can conventionally be air or nitrogen. Whatever the gas flow source used, the installation must allow precise adjustment of the flow rate and a stability control of the gas flow in the lower part of the measuring cell.
- the source of the fluid flow must deliver the fluid at rates such that the resulting velocities are low enough for the measured fluid flow resistances to be independent of the velocity.
- the flow source must make it possible to obtain fluid flow velocities of up to 0.5 ⁇ 10 ⁇ 3 m / s.
- the “micronaire” device represented in FIG. 1 comprises at the orifice 6, a calibrated nozzle.
- This calibrated member, and in particular the diameter of the nozzle orifices, is determined during the calibration of the device.
- the principle of measuring the fineness measurement index is based on a measurement of the permeability of a porous, homogeneous and isotropic medium, this porous medium (in this case a sample of fibers of which wants to know the mean diameter) being crossed by a gaseous fluid, under laminar flow conditions.

- the measuring cell 2 is filled with 5 g of virgin fibers, the measurement of the mass of fibers being carried out using a precision device, (the mass of fibers actually being in the range 5.00 +/- 0.01 g), this mass of fibers having been removed using a shovel, just after the fiberizing tool, and before depositing the binder
- the measuring cell 2 is a cylindrical chamber whose characteristic dimensions are as follows: Inner diameter: 25.4 mm; height: 25.4 mm, the opening of which is closed off by a cover 13.
- the next step consists in adjusting the static differential pressure prevailing between the upstream and downstream of the sample of fibers, by hypothesis, this pressure difference is fixed at 254 mm Hg.
- the device for determining the fineness according to the invention is connected to the device for producing gas flow and the measurement is carried out using the indicator of the volumetric flow meter.
- - fibers for light wound products having a density MV of between 10-11 kg / m 3

- a value of 13.5 l / min corresponds substantially to an average diameter of 3 to 3.5 ⁇ m
- 18 l / min to approximately 4 to 5 ⁇ m.
- the micronaire value (obtained by a traditional device) is not possible for an average diameter of 2.5 to 3 ⁇ m, it is substantially 2.7 for a mean diameter of 3 to 3.5 ⁇ m, and finally 3 to approximately 4 to 5 ⁇ m
