The present invention relates to a kind of method for improving architectural pottery non-slurry pelletizing powder mobility, weight share weighs 100 parts of non-slurry pelletizing powder, 0.05~0.10 part of polytetrafluoroethylene powder, 0.1~0.2 part of graphite powder, 0.5~1.0 part of talcum powder, the high fluidity powder that angle of repose is 30~35 ゜ is obtained after batch mixing, dry ball milling, the mobility of the powder meets the moulding moulded required technical requirements of architectural pottery, therefore with wide market prospects.
Description
Technical field
The invention belongs to technical field of ceramic industry, specifically a kind of raising architectural pottery non-slurry pelletizing powder mobility
Method.
Background technology
The traditional prilling process of architectural pottery is wet ball grinding and then mist projection granulating；But development and skill with society
The progress of art, new prilling process arises at the historic moment, i.e. dry granulation methods.Compared with traditional prilling process, dry granulation methods
It is few with floor space（For the 70~80% of traditional ball milling floor space）, reduction energy consumption（Save energy consumption 30~40%）, reduction make an uproar
More than sound 20dB simultaneously greatly reduces the advantages such as water consumption；Dry method flouring technology meets the policy of national energy-saving emission reduction, has simultaneously
Environment-friendly advantage.But the weak point of non-slurry pelletizing is exactly that the mobility of powder is bad；Therefore, the flowing of dry granulation powder is improved
Property be one of the technical bottleneck for promoting dry granulation technology application.
The content of the invention
To overcome prior art shortcoming and defect, a kind of performance of present invention offer is stable, with low cost, easy to use to be carried
The method of high building ceramics by dry pelletizing material mobility.
To solve above technical problem, the technical scheme is that：One kind improves architectural pottery non-slurry pelletizing powder stream
The method of dynamic property, it is characterised in that：Weight share weighs 100 parts of non-slurry pelletizing powder, polytetrafluoroethylene powder 0.05~0.10
Part, 0.1~0.2 part of graphite powder, 0.5~1.0 part of talcum powder, are made high fluidity powder after batch mixing, dry ball milling.
Ball grinder used in the dry ball milling is zirconium oxide material.
The dry ball milling time is 5 minutes.
The dry ball milling balls mill is oxidation aluminium material.
The material ball ratio of the dry ball milling is 1:1.
The angle of repose of the obtained high fluidity powder is 30~35 ゜.
The mechanism of action of additive of the present invention is：1. talcum powder, graphite powder are laminated structure, in the mechanical milling process of powder
In play a part of chock and be conducive to the broken of powder, while their lubricity very well, can significantly improve the flowing of powder
Property；2. polytetrafluoroethylene powder surface tension is minimum, can significantly improve the mobility of powder.Therefore, these three additives add
Plus the angle of repose of dry method powder powder can be significantly reduced, meet the powder required for dry method powder powder is molded to architectural pottery
The requirement of mobile performance.
The present invention is made by adding polytetrafluoroethylene powder, graphite powder, talcum powder in the powder of architectural pottery dry method powder
For additive, then by quick ball milling 5 minutes, the mobility of powder is significantly improved, the moulding moulded institute of architectural pottery is met
The technical requirements needed, therefore with wide market prospects.
