Description
Technical field:
The present invention is relevant with the weaving part, particularly a kind of manufacture method of woven ceramic product of zirconia flexibilized alumina ceramic.
Background technology:
The present weaving part of textile manufacturing machine, the seal wire spare of spinning for example, cutting members etc. are with metal mostly, this metal spins the requirement that the part wear resisting property can not satisfy the high speed frame.
Summary of the invention:
The technical problem to be solved in the present invention is exactly the defective that overcomes existing metal weaving part, and a kind of manufacture method of woven ceramic product of zirconia flexibilized alumina ceramic is provided, to adapt to the performance requriements of high speed frame to the weaving part.
Technical solution of the present invention is as follows:
A kind of manufacture method of woven ceramic product of zirconia flexibilized alumina ceramic comprises the following steps:
(1), select raw material and press selected each component raw material of weight percent weighing of raw material, become powder through ball mill grinding;
(2), add tackiness agent and mix stirring formation compound;
(3), moulding weaving porcelain spare base substrate;
(4), repair processing;
(5), high temperature sintering, its sintering temperature is 1620 ± 20 ℃, sintering time is 3～8 hours;
(6), at last carry out grinding and polishing, form weaving porcelain spare finished product.
Described raw material is made of following composition:
| Composition | Wt％ | |
| Body material | Aluminum oxide | 66.5～90.7 |
| Toughening material | Zirconium white | 8～25 |
| Auxiliary material | Lime carbonate | 0.5～4 |
| Auxiliary material | Silicon-dioxide | 0.5～3.5 |
| Auxiliary material | Magnesium oxide | 0.3～1 |
Described tackiness agent is a kind of solid paraffin hydrocarbon, beeswax or fatty acid ester macromolecular material, and its addition is 12～14wt% of described raw material.
The moulding of described weaving porcelain spare base substrate is to the smallclothes base substrate employing compound injection molding of complicated shape, to the big part employing compound isostatic pressing of simple shape.
Injection molding base substrate, before high temperature sintering, should be earlier in being higher than 1000 ℃ High Temperature Furnaces Heating Apparatus through 5～10 hours dewaxing treatment.
Progressive effect of the present invention is:
1, Zirconia reinforced alumina ceramic is a kind of modified aluminas pottery, owing in alumina substrate, be evenly distributed with stable Zirconia particles, this material generates metastable state four directions phase in high temperature sintering postcooling process Zirconia particles is in bound state, crack under external force, the part binding force is released, four directions monocline in opposite directions changes mutually and volumetric expansion takes place, phase transformation and the volumetric expansion process of following, except that consumed energy, also produce stress, stop the expansion of crackle, thereby show toughness reinforcing effect in main crackle zone of action, with common aluminum oxide ceramic phase ratio, its fracture toughness property K
ICImprove approximately 30%, show good abrasion resistance and shearing resistance;
2, frictional coefficient only is 2/3 of an alumina-ceramic.
Description of drawings:
Fig. 1, Fig. 2, Fig. 3 are respectively AA, BB, the CC sectional view of special-shaped ceramic guide.
Embodiment:
Be example now, manufacture method of the present invention is described with small-sized filar guide.
The manufacture method of woven ceramic product of zirconia flexibilized alumina ceramic of the present invention comprises the following steps:
(1), select raw material and press each component raw material of raw material weight per-cent weighing, become its granularity of powder to be controlled at below the 2 μ m through ball mill grinding;
(2), add tackiness agent and mix stirring formation compound;
(3), with compound by injection molding or the isostatic pressing porcelain spare base substrate that goes out to weave;
(4), carry out suitable finishing processing after drying, comprise car, cut, bore;
(5), high temperature sintering;
(6), at last carry out grinding and polishing, form weaving porcelain spare.
The specific examples of described composition of raw materials is as follows:
| Composition | Wt％ | ||
| Example 1 | Example 2 | Example 3 | |
| Aluminum oxide | 90.7 | 80.7 | 66.5 |
| Zirconium white | 8 | 15 | 25 |
| Lime carbonate | 0.5 | 2 | 4 |
| Silicon-dioxide | 0.5 | 1.5 | 3.5 |
| Magnesium oxide | 0.3 | 0.8 | 1.0 |
Through ball milling and the powder that grinds to form granularity＜2 μ m, add tackiness agent 12～14wt% and mix, form compound, adopt injection molding technique, make special-shaped filar guide base substrate, as Fig. 1, Fig. 2, shown in Figure 3, after drying, by car, cut, operation such as brill carries out necessary processing to base substrate; Place High Temperature Furnaces Heating Apparatus then, heat up, under greater than 1000 ℃ of conditions, carry out 5～8 hours dewaxing treatment earlier, furnace temperature is increased to 1620 ± 20 ℃ again, sintering 3 hours, cooling is come out of the stove then; To the precision sizing that blank carries out grinding, grinding, polishing, make qualified special-shaped ceramic guide.
Base substrate to the weaving porcelain spare of the big part of simple shape adopts isostatic pressing to get final product.
The weaving porcelain spare that adopts aforesaid method to make, through tentatively test, its performance is greatly improved than common alumina ceramics spare:
Fracture toughness property K
ICBring up to 4.95 by 3.5, increase by 30%, Vickers' hardness reaches HV1264, the anti-intensity 322Mpa that expands, frictional coefficient is 2/3 of a common aluminum oxide ceramic member, makes filar guide and is used for weaving, the intensity of cotton improves 12%, the filoplume rate of cotton descends 15%, and brought up to 2 year by 3 months work-ing life, significantly reduced the servicing time and the expense of frame.
