Description
SPECIFICATION
Dry composition for use in a fibre spraying composition
The invention relates to a dry composition for use in fibre spraying compositions for producing refractory or heat-resistant linings.
It is known to use ceramic fibres in so called fibre spraying compositions. For this purpose ceramic fibres and large quantities of water are first mixed and then either sprayed on to walls or on to ceilings with the aid of a spraying device to produce a refractory or heat-resistant lining or they may be sprayed into hollow spaces.
DE-AS 26 18 81 3 discloses fibre spraying compositions which, in addition to a large proportion of inorganic fibres and low proportions of bonding agent and other inorganic additives, additionally contain a chemical additive bonder, whereby these fibre spraying compositions contain additionally 5 to 20% by weight of an oil to avoid the formation of dust.
In another method, dry ceramic fibres and water are fed separately to the head of a spraying device, mixed with one another in the head of this spraying device and then sprayed on to walls or ceilings or sprayed into hollow spaces. Furthermore, it is also known to add further additives such as bonding agent and other conventional additives to the slurry described above of ceramic fibres in water.
Due to the large quantities of water which are required when spraying it is, however, difficult homogeneously to mix these additives, such as a bonding agent and other conventional additives, with the fibres in the spraying device and to obtain a sprayed composition which adheres adequately to the surface on which it is sprayed.
It is an object of the present invention to provide a dry composition or mixture for use as a fibre spraying composition which can be applied to walls of both metal piate and of brickwork in a layer of a thickness of 30 cm. It is a further object that the composition should be capable of being immediately heated to high temperatures without having to be subjected to a prior drying process.
According to the present invention there is provided a dry composition for use in spraying compositions for the production of refractory or heat-resistant linings containing the following components in an intimately mixed state: a) 100 parts by weight ceramic fibres, b) 2 to 20 parts by weight clay and/or Awl203 and/or Si02 and/or aluminium hydroxides and/or magnesia and/or titanium dioxide and/or chromium oxide, c) 0 to 10 parts by weight fire clay powder, d) 2 to 8 parts by weight of a phosphate bonding agent, calculated as P2Os, and e) 1 to 4 parts by weight of a solid organic bonding agent.
The ceramic fibres in the composition in accordance with the invention can be all the conventional fibres of this type, e.g. mineral fibres, such as rock wool, or fibres based on aluminium silicate, preferably with a particularly high Awl203 content in the region of 45 to 95% by weight. Naturally mixtures of different ceramic fibres can also be used.The fibres are, however, preferably based on Al203 and Si02 with at least 40% by weight Awl203 and are preferably capable of being used at temperatures in excess of 1 100'C. This will in general exclude inorganic fibres based on, for instance, basalt, slag and glass and natural asbestos fibres whose use temperature is below 11 00 C, but such fibres may be used as a subsidiary component in addition to those whose use temperature is above 11 00 C.
Advantageously the ceramic fibres are present in loosened form. For this purpose, commercial fibres are put in the state in which they are usually delivered in an impact mixer (e.g. a
Turbulent-Rapid Mixer manufactured by Drais), in which the fibres which are commonly delivered as fibre bundles are converted into loosened fibres. Such an impact mixer comprises a mixing unit with rapidly rotating knife heads by means of which any agglomerates which may be present in conventional fibres, which are frequently partially present in a strongly compressed form, are loosened, without the fibres being thereby unacceptably crushed or comminuted.
The clay present in the composition in accordance with the invention can be a conventional clay or a special bonding clay, e.g. bentonite. This clay is preferably used in an amount of 5 to 20 parts by weight 10 to 100 parts by weight of the ceramic fibres and advantageously 8 to 1 5 parts by weight clay are used.
The components which may be present in the composition in addition to or instead of the clay are, in accordance with the invention, Awl203 and/or Si02 and/or magnesia and/or titanium dioxide and/or chromium oxide, all of which are preferably present in very finely divided form, and/or aluminium hydroxides. These are components whose use is known in the refractory field. The term "very finely divided" used in conjunction with the components referred to above means that these components are present in a very finely ground state or in the colloidal state.
The very finely divided refractory materials preferably have a grain size of less than 50 ym, more preferably less than 10 ym. Particularly when using such materials in the colloidal state, such as colloidal SiO2 or colloidal aluminium oxide, it is possible to use only small quantities of bonding agent, that is to say close to the lower threshold value of 1 part by weight of an organic bonding agent and 2 parts by weight of a phosphate bonding agent. The use of approximately the same parts by weight of phosphate bonding agent and methyl cellulose as organic bonding agent is particularly preferred.It is also particularly advantageous to use a mixture of clay and one or more of the other refractory components referred to above, the quantity of these other refractory components being preferably 1 to 3 parts by weight and the remainder clay so that the amount stipulated in the main claim of 2 to 20 parts by weight of refractory components is present. Additionally 0 to 10 parts by weight fire clay powder are present in the composition in accordance with the invention. This can be any desired finely ground fire clay and preferably the maximum grain size of the powder is < 63 ,um and particularly preferably < 44 ,um.
Additionally 2 to 8 parts by weight and preferably 3 to 6 parts by weight of phosphate bonding agent are present in the composition in accordance with the invention, the given quantities in parts by weight referring to P205 in the bonding agent or mixture of bonding agents. An example of suitable phosphate bonding agents is sodium polyphosphate with a degree of polymerisation of n24 and preferably with a degree of polymerisation of 6 to 10. This sodium polyphosphate is used in solid form. A further phosphate bonding agent is monaluminium phosphate that is a commercial product available in solid ground form.
A solid organic bonding agent is present in the composition in accordance with the invention.
For this purpose all organic bonding agents commonly used in this field may be used, for instance methyl cellulose, sulphite lye or waste or molasses.
In the production of the dry composition in accordance with the invention the individual components are put into a mixer in any desired order. For this purpose a conventional mixer or an impact mixer as was described above can be used. Instead of using fibres which have already been loosened for producing the compositions in accordance with the invention, commercial ceramic fibres can also be put into such an impact mixer together with the other components and the loosening of the ceramic fibres and the intimate mixing with the other components carried out in it simultaneously.
The dry compositions in accordance with the invention can be sprayed with a conventional spraying machine of the type which is common in concrete processing technology. For this, the water necessary for setting is fed to the spray nozzle. Since the compositions in accordance with the invention are in the form of an intimate mixture with bonding agents homogeneously distributed within them the quantity of water which is required is much less than with known dry compositions which can also be sprayed in this manner.
Certain specific embodiments of the invention will now be described in more detail by way of example with reference to the following Examples.
In the Examples ceramic fibres A and B were used which had the following chemical composition:
Fibres A) Al203 = 47%; Si02 = 53%
Fibres B) Awl203 = 95%; Si02 = 5%.
Example I
The following composition was used:
Parts by weight
Ceramic fibres A 100
Bonding clay (with 35% Awl203) 10
Fire clay powder < 63 jum 10

These compounds were thoroughly mixed for 20 minutes in an Eirich mixer.
The dry mixture was sprayed in a spraying machine, to the nozzle of which it was fed by pressurized air and there mixed with water also fed to the nozzle.
Sprayed thicknesses on perpendicular walls of metal plate of 30 cm could be produced with this composition. The sprayed mass could be heated immediately without particular drying.
Such a sprayed on mass had the properties given in the following table, the different columns containing the properties after heating at a given temperature for a given period of time:
