Sintering process is different.Can be seen that when comparative example uses dry pressuring forming process molding, owing to raw material containing water
Point, after molding, the demoulding is relatively difficult, easily causes sizing, the phenomenon such as come off and compact strength inadequate, fortune
Easily cause deformation during defeated or damage.And embodiment 4 uses injection moulding, the sample of extrusion is due to viscous
Knot agent fast setting at low temperatures so that sample surfaces is smooth, not with die bonds, the easy demoulding, and sample
Product have certain intensity, are difficult to the situations such as deformation breakage occur in transportation.
It follows that during follow-up sintering, use dry pressuring forming process molding unbalance stress, pressed compact burns
The phenomenon such as the most cracking, destruction during knot；As long as and injection moulding keeps shot forming process
In injection temperature, injection pressure, these technological parameters of dwell pressure and time constant, the porous pottery for preparing
Ceramic material stable performance, even structure, decrease the cracking destruction phenomenon in sintering.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the most right
The all possible combination of each technical characteristic in above-described embodiment is all described, but, if these skills
There is not contradiction in the combination of art feature, is all considered to be the scope that this specification is recorded.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But can not therefore be construed as limiting the scope of the patent.It should be pointed out that, for this area
For those of ordinary skill, without departing from the inventive concept of the premise, it is also possible to make some deformation and change
Entering, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended power
Profit requires to be as the criterion.
