Description

A process for the production of abrasives, the invention relates to a process for the production of abrasives.

Such abrasives are incorporated in, for example, abrasive coatings, in full or in abrasive grinding papers. Here, as a bond for the abrasive all known ceramic compounds and resin bonds are contemplated. Application of said grinding tools are grinding steels, metals and alloys, plastics and wood.

Various methods for producing abrasive agents are known from the prior art. For example, 201 1/087649 discloses the WO, a method in which a rotating perforated mask is used in combination with negative pressure thereto to prepare molded ceramic material segments which are sintered subsequently. This is a technically elaborate and maintenance-intensive process.

The object of the subject invention is to essentially a simplified process for the production of abrasives to be indicated.

This object is achieved by the following process steps:

i. Providing a combustible reticular or grid-shaped structure, preferably of plastic, with a plurality of openings on a carrier, preferably an endless carrier belt,

Ii. Providing a, preferably aluminum-containing starting mixture, which is convertible by sintering at least aluminum oxide, wherein the starting mixture is preferably flowable,

iii. Filling the openings with the starting mixture, and

iv. Sintering the filled with the starting mixture reticular or grid-like structure.

One of the basic ideas of the inventive method consists in the fact that during the step of sintering the one hand, the starting mixture is transferred at least in alumina and the other, the net-like or lattice-like structure is burned, which has an automatic separation of the abrasive particles to the sequence, so that the abrasive particles after sintering - at least for the most part - separate from one another. An essential advantage of the inventive process over the prior art is that the geometry and dimensions of the abrasive particles can be determined by the choice of the shape of the net-like or lattice-like structure in a simple manner. It is also possible to change quickly and easily by changing the mesh or lattice-like structure, the geometry and size of the abrasive particles produced.

It should be noted that the technique, one, preferably containing aluminum hydroxide to convert the starting mixture by sintering at least alumina, has been known for some time. In this connection to the so-called "sol-gel process" referred to. If the starting mixture aluminum hydroxide may have different modifications, such as boehmite, are used. Depending on the starting mixture, it may happen that in addition to aluminum oxide (typically as alpha-alumina) secondary phases such as spinel, arise. this fact is supported by the phrase "at least in alumina" bill.

In an advantageous embodiment of the process with the initial mixture filled net or mesh-like structure prior to sintering is pre-dried, preferably at a temperature between 50 ° Celsius and 500 ° Celsius, more preferably at a temperature between 150 ° Celsius and 400 ° Celsius. In this way can be converted to filled with the starting mixture reticular or grid-shaped structure in a state of, for example, plate-like sections allows the subdivision in, preferably. These sections can then be supplied subsequently to the step of sintering.

However, alternatively or additionally, it is also possible that the starting mixture with the filled net or mesh-like structure on the carrier remains and the sintering is carried out in a continuous furnace.

The sintering is preferably carried out at a temperature between 1200 ° C and 1800 ° C, more preferably at a temperature between 1200 ° C and 1500 ° C.

It lends itself to the net or lattice-like structure to use a material that burns completely at the sintering temperature, but at lower temperatures - for example at a possible Vortrockungsprozess - is heat resistant.

Preferably, the (single layer) on the support provided reticular or grid-shaped structure viewed from the side has a height less than or equal to 1, 5 millimeters. This height corresponds substantially to the thickness of the threads or webs from which the net-like or lattice-like structure is advantageously constructed. Moreover, this level determines the thickness of the present at the end of the manufacturing process abrasive particles, as the starting mixture - if it is flowable - flows during filling of the openings on the boundary of an opening in the form of threads or webs and into an adjacent opening. It must however still be considered that the thickness in the course of the sintering process - mainly due to the reduction of the liquid content - even decreases. In general it should be noted that different net-shaped and lattice-like structures characterized in that reticular structures, in contrast to the lattice-shaped structures comprise nodes.

If it is a somewhat more viscous starting mixture, it can be provided as alternative or complementary measure to ensure a certain thickness of the abrasive particles that happen to the starting mixture filled net or mesh-like structure prior to sintering, a gap having a predetermined height. This height is advantageously the height of the on the support provided set reticular or grid-like structure or the strength of the filaments or webs of the reticular or grid-like structure or slightly above so that the starting mixture is in painted uniformly in the apertures. As geometries for the openings in the mesh or lattice-like structure offer polygons, preferably diamonds, squares or triangles on.

Depending on the choice of the specific process parameters, it may happen that the sintered products obtained by sintering abrasive particles or are sporadically connected via webs or the like with each other. In these cases, it is advantageous for the obtained sintered products by sintering of a separating device, preferably supplied to a vibrator.

Further advantages and details of the invention will be apparent from the figures and the related specific description. They show:

FIGS. 2a and 2b, two advantageous embodiments of the invention based on

Schematic drawings,

FIGS. 3a and 3b two possible in the method, the used mesh or lattice-like structures, and FIGS. 4a and 4b two possible means of the inventive method can be produced

Abrasive particles.

1 shows a flowchart showing the four basic steps of the method 1 of the invention for the production of abrasives, namely

i. providing a combustible reticular or grid-shaped structure, preferably of plastic, with a plurality of openings on a carrier, preferably an endless carrier Brand,

ii. providing a containing, preferably aluminum hydroxide, the starting mixture, which is convertible by sintering at least aluminum oxide, wherein the starting mixture is preferably flowable,

iii. filling the openings with the starting mixture, and

iv. sintering the filled with the starting mixture reticular or grid-like structure.

The technical realization of this process can be done in different ways, two particularly preferred embodiments are shown in Figures 2a and 2b:

In the case of Figure 2a providing the combustible reticular or grid-like structure 4 is carried on a support in the form of a continuous carrier strip 10 by unwinding of the net or grid-like structure 4 15 from a roll The angular speed of this roller 15 and the speed of the endless carrier belt 10 are thereby matched to ensure a smooth unwinding of the net or grid-like structure. 4 The endless carrier belt 10 is guided by the rolling elements. 16 and 17

After providing the combustible reticular or grid-like structure 4, which consists in this case of plastics material, the openings 6 of the same (cf. Fig. 3a.) With a flowable starting mixture 8, which (by sintering at least in alumina and further above executed can be transferred into any secondary phases), and which contains in this case mainly aluminum hydroxide filled. For this, the starting mixture is poured 8 on the net-like or lattice-like structure. 4 The filled with the starting mixture 8 mesh or lattice-like structure 4 and then passes through a gap 13, whose height substantially corresponds to the height 18 of the single-layer provided on the carrier 10 mesh or lattice-like structure. 4

The filled with the starting mixture 8 mesh or lattice-like structure 4 is finally transported by means of the endless carrier belt 10 through a continuous oven 14, in which the drying process and the sintering takes place. The portions of the starting mixture 8, which are located in the openings of the net-like or lattice-like structure 4 are sintered to form alumina particles, on the one. Simultaneously, the net or grid-shaped structure burns 4. That is, after the step of sintering the abrasive particles 2 are present according to the predetermined geometry of the net-like or lattice-like structure 4 on the endless carrier belt 10th Finally, the abrasive particles 2 are collected in a collection container.

In the case of the embodiment of the method according to the invention 2b schematically illustrated in the figure, the two process steps of "providing a combustible reticular or grid-like structure" and "filling of the openings thereof" embodiment, as in the illustrated similarly in the figure 2a effected. However, filled with the starting mixture 8 mesh or lattice-like structure 5 is then pre-dried before sintering by means of a heater 19, and at a temperature between 150 ° Celsius and 400 ° Celsius. At this temperature, the net or grid-like structure 5 is heat-resistant. By pre-drying the feed mixture fluid is withdrawn, so that it is less flexible and adheres to the net-like or lattice-like structure. Therefore, the filled with the starting mixture 8 mesh or lattice-like structure can be divided 5 by means of a suitable device in plate-shaped portions 9, which are supplied subsequently a sintering furnace 20th

In the sintering furnace 20, the step of sintering, in turn, is performed, wherein the starting mixture 8 transferred at least into alumina and any secondary phases, while the net-like or lattice-like structure 5 is burned, so that takes place a separation of the abrasive particles 3 during sintering.

As stated above, the geometry of the abrasive particles produced by the method can be determined by the geometry of the net-like or lattice-like structure. Figures 3a and 3b show two exemplary network geometry namely, first in the case of FIG 3a is a reticular or grid-like structure 4, the openings are diamond-shaped, and on the other hand in the case of figure 3b is a reticular or grid-like structure 5, the openings are square formed. The threads or ridges 1 1 and 12, the net-like or lattice-like structure 4 and 5 have a thickness less than or equal to 1, 5 millimeters. The net-like or lattice-like structures 4 and 5 can be used both in the embodiment according to figure 2a as well as in the embodiment shown in Figure 2b. It is also conceivable to use a net-like or lattice-like structure having openings of various geometries, and produce a mixture of abrasive particles with correspondingly different geometries in this way.

Figures 4a and 4b show two examples of producible by the method of abrasive particles, wherein the particles 2 4a has a diamond shape having a predetermined edge length 22 in the figure and the particles 3 in the Figure 4b, a square shape having a predetermined edge length 24. These geometries of the abrasive particles 2 and 3 correspond to the mains or grid geometries shown in figures 3a and 3b. The thickness of the abrasive particles 25 and 26 is - due to the fluid removal during the sintering process - less than the thickness of the filaments or webs of the reticular or grid-like structure.
