Split toughness to greatly improve, wear-resisting, corrosion-resistant, resistance to erosion, service life is greatly prolonged, and is widely applied to oil, chemical industry, ore deposit
In the industrial and minerals such as mountain, thermoelectricity complexity industry.
3rd, content of the invention
The purpose of the present invention is overcome the shortcomings of in prior art, provides a kind of process is simple, article of manufacture cost bottom, is produced
Product are wear-resisting, corrosion-resistant, resistance to erosion, intensity and toughness are greatly improved, the ZnOw of long service life strengthens aluminium oxide ceramics
The research of preparation technology.
The object of the present invention is achieved like this：A kind of ZnOw strengthens the research of aluminium oxide ceramics preparation technology,
It is characterized in that：Its formula is that its mean diameter is less than 1 micron based on alumina powder, adds 10--30% average length to exist
ZnOw of the 2--6 micron through overpickling；The raw material for weighing by formula is put in sand mill, adds 0.2--0.5% oil
Acid, it is alumina balls that ball milling 6--10 hour, wherein ratio of grinding media to material are 4: 1--6: 1, ball-milling medium, and the raw material for processing goes out honed 60
Mesh sieve, is put into the raw material for sieving in batch mixer and adds 0.3--0.5%PAV, 0.3--0.5% yellow starch gum, batch mixing, mixes
The material time is 2--6 hour, and discharged 40 mesh sieves, the old 40--60 hour of the raw material to mixing, and keeps moisture in 0.4---
Between 0.8%；Compound is become by 180--250 MPa of pressurize 3--8 minute isostatic pressed in a mold according to the structure of product
Ceramic blank made by type, then repaired biscuit；High temperature sintering is carried out to the ceramic blank through repaired biscuit, sintering temperature is 1550--1620
DEG C, 2--4 hour is incubated, programming rate is 80--120 degree per hour, furnace cooling after sintering；According to size and technical requirements pair
Polish is carried out through the chromium carbide ceramics porcelain base of high temperature sintering, make ZnOw and strengthen aluminium oxide ceramics；Zinc oxide crystalline substance
Through pure water and pure industrial alcohol, cleaning 2--4 time must be repeated again after the chlorohydric acid pickling of 1--10% concentration, so
Post-drying.
The invention discloses a kind of ZnOw strengthens the research of aluminium oxide ceramics preparation technology, with alumina powder it is
Base, adds the ZnOw of 10-30%, and raw material is put into ball milling in sand mill, batch mixing, old one timing of sieving in batch mixer
Between after isostatic pressing, then the blank through repaired biscuit is sintered into ceramic porcelain base under the high temperature conditions, according to the size of product
And technical requirements carry out polish to ceramic porcelain base.Preparation process is simple of the present invention, product qualified rate height, low cost of manufacture, produce
Product hardness is big, bending strength and fracture toughness are greatly improved, wear-resisting, corrosion-resistant, resistance to erosion, and service life is greatly prolonged, extensively
Apply the industrial and minerals such as oil, chemical industry, mine, thermoelectricity complexity industry in.
