Abstract

The invention discloses a kind of piezoelectric ceramic atomizer patch preparation methods, belong to the production method of piezoelectric ceramics.Its method be include granulation, blank forming, sintering, specific method is: ceramic powder is mixed with polyvinyl alcohol by the weight ratio of 100:0.03-0.06, put into mixing machine in stir evenly；It is transferred to pelletizer to be granulated, be sieved, control pelletizer pressure is 0.5-1T/cm2, discharging speed 2-2.5Kg/min；Pellet is sent into oven drying, and being then pressed into density is 5.2-5.45g/cm3Disc-shaped green body；By the blank sintering at potsherd.It is suitable with the piezoelectric ceramic atomizer patch quality using Spray granulation method preparation using the piezoelectric ceramic atomizer patch of the method for the present invention preparation, but the production efficiency of the method for the present invention is the 2 times or more of Spray granulation method, and energy consumption is only 1/3 of Spray granulation method or so.

Description

Piezoelectric ceramic atomizer patch preparation method
Technical field
The present invention relates to a kind of preparation method of piezoelectric ceramic piece more particularly to a kind of preparation sides of piezoelectric ceramic atomizer patch Method.
Background technique
Piezoelectric ceramic atomizer patch because have small in size, light-weight, contactless, noiseless, low in energy consumption, the highly reliable, long-life, The features such as being adapted to severe working environment is widely used in environmental project, medical instrument, auto industry, stage equipment And the fields such as household electrical appliance.Since piezoelectric ceramic atomizer patch size is thicker, granulation, drying, dry-pressing formed side are generallyd use It is prepared by formula.Be granulated currently, generalling use spray pattern in large-scale production: ceramic powder mixes with plasticiser Even formation slurry, then slurry is sprayed into granulation tower by sprayer and is atomized, dried, obtain the preferable granule of quality.It should The advantages of method is granule good fluidity, yield is big, continuous production can be achieved, but that there are mass output rates is low, energy consumption is high, pollution is larger The defects of.
Summary of the invention
In order to overcome drawbacks described above existing in the prior art, the present invention is intended to provide a kind of mass output rate height, less energy consumption, dirt Contaminate lesser piezoelectric ceramic atomizer patch preparation method.
To achieve the goals above, the present invention includes granulation, blank forming, sintering using technical solution, and specific method is such as Under:
1) ceramic powder is mixed with the polyvinyl alcohol that weight percent concentration is 15% by the weight ratio of 100:0.03-0.06, so It puts into mixing machine afterwards, first stirs at low speed 3-5min, then high-speed stirred 10-15min again；
2) mixture stirred evenly is transferred to pelletizer progress precompressed, broken, whole grain, crosses 60-80 mesh, control pelletizer pressure Power is 0.5-1T/cm2, discharging speed 2-2.5Kg/min；
3) sieving gained pellet is sent into 120 DEG C of oven drying 10-15min；
It 4) is 5.2-5.45g/cm by density is pressed by the pellet being dried3, with a thickness of the disc-shaped base of 0.8-2mm Body；
5) by the blank sintering at potsherd.
Compared with the prior art, therefore the present invention is by adopting the above-described technical solution, have many advantages, such as, concrete analysis It is as follows:
1) it is granulated using mechanical system, few relative to mist projection granulating adhesive therefor, moisture is small, rate of drying is fast, energy consumption is small, more Easy dumping；
2) being granulated using mechanical system has high production efficiency, low energy consumption, mass output rate is high (can mix 300-500Kg per hour Material) the advantages that；
3) suitable granule density, bulk density 1.95-2.35g/cm can get using the method for the present invention3, it is greater than spraying Bulk density (the 1.75-1.85g/cm of granulation material3)；
4) the granule shapeliness obtained using the method for the present invention, material is (can produce 120-150Kg per hour) high in machining efficiency, fits It closes and produces in enormous quantities；
5) the ceramic body density of the method for the present invention preparation is up to 5.2-5.45g/cm3, greater than the pottery of Spray granulation method preparation Porcelain billet volume density (5.0-5.15g/cm3)；
6) ceramics atomizing piece made of the method for the present invention, for atomization quantity up to 250-700 mls/hour, service life is reachable It is 5000-10000 hours, suitable with mist projection granulating；But the production efficiency of the method for the present invention is the 2 times or more of Spray granulation method, Energy consumption is only 1/3 of Spray granulation method or so.
