Definitions
- the present invention relates to the field of mineral fibers; more specifically, it targets mineral fibers whose composition is such that they degrade as soon as they are in contact with a physiological medium.
- the present invention relates to mineral fibers which dissolve quickly in such a solution, while retaining good mechanical strength when subjected to heat.
- the presence of alkaline oxides, in particular Na2 ⁇ , and / or the presence of phosphorus pentoxide in the composition of the mineral fibers defined above makes it possible to increase their rate of dissolution in a solution simulating a extracellular fluid.
- the mineral fibers contain at least 2% by weight of a 2 ⁇ and / or phosphorus pentoxide, the sum of the alkali oxides not exceeding 6.5% by weight. Within preferred limits, the sum of the alkali oxides is between 1 and 6%.
- Silica is a constituent which decreases the speed of dissolution of the fibers.
- Al2O3 and iron oxides are not essential in the fibers according to the invention, their presence in their composition improves their mechanical strength, together with the addition of alkaline earth oxides.
- the mineral fibers according to the invention exhibit good mechanical strength when they are subjected to heat thanks, in particular, to the fact that their composition comprises lime, magnesia and iron oxides in proportions such that the sum of the contents of these oxides exceeds 23% and preferably 25%.
- the fibers according to the invention include the following constituents according to the following weight proportions:
- the most advantageous fibers according to the invention comprise less than 4% of Al 2 O 3 .
- Fe2 ⁇ 3 content of the fibers according to the invention is equal to or greater than 7%
- their Al2O3 content is preferably equal to or less than 1%
- their P2O5 content is preferably greater than 1%.
- the fibers corresponding to the compositions appearing in table n ° 1 were obtained from a fluid drawing device, of the type of those described in patents US-A-3,532,479 and US-A-4,961,695 .
- the distribution of the diameters of the fibers tested, corresponding to Examples No. 1 to 8, is such that 50% of them have " a diameter respectively less than 2.2 ⁇ m - 2.5 ⁇ m. - 3.1 ⁇ i ⁇ - 3.7 ⁇ m - 3.5 ⁇ - - 3.4 dm - 3.7 m
- the ability of these fibers to be dissolved in a physiological medium was measured under the following experimental conditions: two hundred milligrams of fibers are placed between two perforated discs, separated by a circular ring.
- This set constitutes a measuring cell through which a solution simulating circulates an extracel ⁇ lular fluid whose flow rate is regulated by a peristaltic pump This flow rate is 40 milliliters per day, the duration of the test being 42 days
- the cell and the bottle containing the attack solution are maintained at 37 ° C. After crossing the cell, the solution of ttaque is collected in bottles for later analysis.
- the quantity of silica passed in solution is measured; the weight of dissolved silica relative to the weight of silica initially present in the fiber gives a result in percent, which is a good indicator of the capacity of the fiber tested to degrade in physiological medium.
- the attack solution chosen has the composition where the content of each constituent is expressed in g / 1:
- the mechanical strength of the fibers tested when they are subjected to heat was measured under the following conditions: a cubic sample of fibers, which has a density of approximately 100 kg / m 3 , is placed in a tube furnace whose temperature rise, programmed is 5 degrees centigrade per minute. The collapse of the sample is measured by optical sighting. The temperature at which the block has a sag of 10% was used as an element for assessing the mechanical strength of the fibers tested. The different results concerning the dissolution of the fibers tested and their mechanical strength are set out respectively in Tables 2 and 3.
- the composition serving as a comparison element corresponds to Example No. 1. This is a classic basalt composition, in which the contents of iron oxides and alumina are high.
- the composition corresponding to Example No. 2 illustrates the fibers according to the invention for which the high silica content is compensated for by the addition of Na2 ⁇ . If the speed of dissolution of the corresponding fibers is - high, their mechanical strength remains lower than that of basalt. Compared to the previous one, the fibers whose composition corresponds to Example No. 3 have a slightly improved mechanical strength, but a slightly lower speed of dissolving, probably due to the content of iron oxides. This decrease in the speed of dissolution is very largely compensated by the introduction of P2O5 as shown in Example No. 4. This dissolution rate can be further greatly increased, by maintaining or even improving its temperature resistance as shown in the example No. 5.
- those which exhibit a good compromise between the dissolution rates and the highest mechanical strengths are those whose Si ⁇ 2 content is between 52 and 62%, the content in magnesia being at least 3% and the content of alkaline oxides between 1 and 5%.
- the fibers according to the invention have a temperature corresponding to a slump of 10% at least equal to that of basalt.
- compositions of these fibers are illustrated by Examples No. 5 to 6.
- Table No. 4 brings together other compositions corresponding to the invention.
- the ability of these glasses to be dissolved in a physiological medium was measured by means of a test carried out on mechanically ground glass under the following conditions: * the glass grains obtained by grinding are sieved and the fraction particle size between 355 and 400 micromè ⁇ very is used for the test. The grains thus selected are washed with alcohol and dried in an oven. One gram of this glass powder is placed in the cell identical to that described above,
- the solution used is slightly different from the previous one as regards the NaCl and CaCl2 contents, which are 6.6 and 0.022 g / 1 respectively. It includes surcr ⁇ ilo 1.08 g / 1 formaldehyde, * the rate of this solution is 300 milliliters per day and the test duration is two weeks, with intermediate measurements of one day and one week.
- example N ° 1 which serves as a reference is identical to that appearing in table N ° 1.
- the attack on glasses No. 9 to 11 is much higher than on the reference glass, but the influence of the composition does not emerge at such an early stage of the attack. It is no longer the same after a week.
- the increase in the Fe2O3 content is probably at the origin of the reduction in the quantity of dissolved silica, but surprisingly this reduction is relatively small.
- With a content of 10% of F ⁇ 2 ⁇ 3 the glass example N ° 11 is still about ten times more soluble than the reference glass.
- Glasses No. 12 and 13 show that the introduction of P2O5 and the almost total suppression of AI2O3 make it possible to reach high dissolution rates despite the high Fe2O3 content and the absence of alkaline oxides.
- Glasses No. 15 to 18 illustrate intermediate variants relative to the contents of F ⁇ 2 ⁇ 3 and AI2O3, but with alkaline oxides.
- Glass No. 14 illustrates the compositions without iron oxide and which has a high dissolution rate despite a high content of Al2O3.
- a category of preferred compositions corresponds to those defined by a content of phosphorus pentoxide of between 1 and 4%.
- the glasses according to the invention can be transformed into fibers from known external centrifugation devices, such as those described for example in patents US-A-2,663,051, EP-A-0.167.508 or FR-A-2.609. 708.
- the fibers thus obtained make it possible to obtain fibrous products of excellent quality suitable for numerous applications.
- the fibers according to the invention are advantageously used in the form of geometrically well defined panels, stiffened by a polymerized binder, or in the form of tubular products intended to insulate the pipes.
- the fibers according to the invention can also be used in the form of mattresses sewn onto cardboard or wire mesh, in the form of a bead, or even in bulk by filling. TABLE N ° 1
- compositions in weight percentages are compositions in weight percentages.
- compositions in weight percentages are compositions in weight percentages.
