Abstract
The present invention is for when preparing new material powder by liquid phase method, tradition molding is big to the demand of powder, more, powder shape is lost and property is easy the disadvantages of changing, a kind of use for laboratory powder granule centrifugal forming device is invented, centrifuge tube including bottom of which has holes, it is centrifuged side wall, molding cylinder, shaping base, centrifugation pedestal, contoured squeeze board, demoulding pedestal, powder granule is first preforming in being centrifuged preforming system, then the compression moulding in press-moulding die system.The present invention is suitble to laboratory to use when preparing the molding of a small amount of powder granule, the defect that several grams or less powder granule can be formed, while powder reuniting, powder structure and property being avoided to change, and can be reduced experimental procedure, and convenient formation is quick.
Description
Technical field
Being used the present invention relates to a kind of centrifugal forming device and its application method more particularly to a kind of suitable laboratory,
Molding centrifugal forming device is carried out after preparing a small amount of powder granule by liquid phase method.
Background technique
It is all much to first pass through the liquid phase method such as precipitation method, hydro-thermal method, water when laboratory carries out new material research or exploitation
The methods of solution prepares new material powder, needs further to separate powder with liquid later, dries, is levigate, molding, heat
Processing or sintering, block materials are made and study its performance.But the new material powder granule prepared when generally testing
Amount it is fewer, such as powder quality only has tens grams, several grams or less, and the amount ratio for the powder that common forming method needs
More, whole process loss is larger, and is easy to reunite after drying, then the powder after drying is changed to the shape of powder when levigate
And property, thus affect the performance of material.General centrifugal formation method is mainly used in the centrifugation of the products such as hollow cement
Molding, and the powder of the components such as ceramics, metal are made suspended nitride centrifugal forming again, huge construction and are first made outstanding
The method that laitance material carries out centrifugal forming again is not suitable for the centrifugal forming of a small amount of powder when new material experiment.Based on small-sized centrifugation
The powder granule and liquid phase separation that machine prepares liquid phase method, and pressed again using centrifugal forming device by powder granule is preforming
Type is made, can be convenient the heat treatment for efficiently carrying out new material and performance test experiment.
Summary of the invention
When the present invention is for powder is prepared using liquid phase method in the exploitation of existing new material research, the amount of the powder of preparation compared with
Less, when then being separated with liquid by powder, dry, is levigate, forming, being heat-treated or sintering into block materials and studying its performance, powder
The disadvantages of demand of body is big, more, powder the shape of loss and property are easy change proposes a kind of to prepare liquid phase method
After original powder cleaning, first carry out being centrifuged preforming, the re-compacted device at block materials.Technical scheme is as follows：
A kind of use for laboratory powder granule centrifugal forming device, the centrifuge tube including bottom of which has holes are centrifuged side wall, shaping column
Body, shaping base, centrifugation pedestal, contoured squeeze board and demoulding pedestal, it is characterised in that：Centrifugation side wall and molding cylinder are entrenched in one
It rises, centrifugation lower sidewall is entrenched togather with shaping base, and centrifugation lower sidewall is that scalariform is hollow；Being centrifuged pedestal is cylinder
Hollow shape, is centrifuged pedestal and shaping base is entrenched togather；Molding cylinder is hollow cylindrical, the top of molding cylinder and molding
Pressure head lower part coincide, and the lower part of molding cylinder and the top of shaping base coincide；Demoulding the middle of the base is hollow spill, for compacting
It is detached from the slave molding cylinder of shaping base and molding sample after molding and space is provided.
The use for laboratory powder granule centrifugal forming device, it is characterised in that：It is centrifuged side wall and is centrifuged the material of pedestal
Matter be loose porous polymer material, molding cylinder, contoured squeeze board, shaping base and demould pedestal material be stainless steel or
Mould steel.
The use for laboratory powder granule centrifugal forming device, it is characterised in that：The centrifuge tube of bottom of which has holes, centrifugation side
The preforming system of centrifugation that wall, molding cylinder, shaping base, centrifugation pedestal and contoured squeeze board are constituted；Molding cylinder, contoured squeeze board
Press-moulding die system is constituted with shaping base；Powder granule be put into the preforming system of centrifugation be centrifuged it is preforming；It takes out
Molding cylinder, shaping base and preformed powder granule, form powder particle in press-moulding die system, most
Press-moulding die system is placed on demoulding pedestal afterwards and applies appropriate pressure, the sample of forming is taken out.
The present invention has following beneficial effect：
(1) powder granule centrifugal forming device be very suitable to laboratory using liquid phase method prepare a small amount of powder granule form when
It uses, several grams or less powder granule can be formed into flakiness or cylindric material.
(2) present apparatus a small amount of liquid in top in centrifugal forming can be absorbed by porous centrifugation side wall, the liquid of lower part
Body can flow to centrifugation pedestal by the gap between molding cylinder and shaping base, absorb or pass through centrifugation by centrifugation pedestal
The circular hole of pedestal is discharged.
(3) present apparatus can be changed to avoid powder reuniting caused by traditional molding method for preparing, powder with structure and property
The defect of change, and can be reduced experimental procedure, forming process is convenient and efficient.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of use for laboratory powder granule centrifugal forming device；
Figure label：The centrifuge tube of 1- bottom of which has holes；2- is centrifuged side wall；3- molding cylinder；4- shaping base；5- is centrifuged bottom
Seat；6- contoured squeeze board；7- demoulds pedestal；8- powder granule.
Specific embodiment
The invention proposes a kind of use for laboratory powder granule centrifugal forming devices, below by Detailed description of the invention and specifically real
Applying example, the present invention will be further described.
Use for laboratory powder granule centrifugal forming device as shown in Figure 1, centrifugation side wall 2, the material for being centrifuged pedestal 5 are micro-
Hole rubber, the material of molding cylinder 3, shaping base 4 and demoulding pedestal 7 are mould steel.Will centrifugation pedestal 5, shaping base 4, at
Type cylinder 3, centrifugation side wall 2 are sequentially placed into the centrifuge tube 1 of bottom of which has holes, by 2-3 grams it is cleaned, pass through coprecipitation preparation
