Background technology
Ceramic injection forming technique is a kind of high technology ceramics forming method grown up on the basis of polymer injection forming technique, it can high efficiencyly be produced in batches, and accurately can control technological process, due to controllable precise, the plastic complex-shaped ceramic component of its compact dimensions, make injection molding in ceramic molding, occupy indispensable status.
In the prior art, the main technique of producing at present ceramic sheet is the shaping and flow casting molding of hydrogel, but the production cycle of hydrogel moulding process is long, and volume production efficiency is low; The requirement of flow casting molding to powder body material is high, and general powder body material can not meet the final performance of ceramic product.
Summary of the invention
The object of the invention is to provide the making method of a kind of crowded film shaping production stable composition zircon ceramic thin stock material, by using the method, improves the production efficiency of ceramic sheet.
For achieving the above object, the technical solution used in the present invention is: the making method of a kind of crowded film shaping production stable composition zircon ceramic thin stock material, the steps include:
1. modification is carried out to stable composition zirconium powder body: select mixing and blending machine, three-roller and refrigerator,
A. first add HPMC, glycerine and deionized water in stable composition zirconium powder body, be positioned in mixing and blending machine and stir;
B. be positioned over three-roller top roll 3 times again, make powder stirring full and uniform;
C. again the powder preservative film stirred is wrapped, put into refrigerator and place for some time and carry out for subsequent use;
2. ready powder feeding squeezed in film machine, the thickness of product regulates crowded film machine as required, and the scope of product thickness is 0.3mm ~ 1mm, then is dried in the cocycle of oven dry material transport tape by the film extruded, and it is for subsequent use to coil rolling;
3. according to the size press tool of ceramic blank intending producing, by step 2. in the product that obtains on punch press, go out the ceramic blank of drawing up;
4. ceramic blank sintering: ceramic blank is burnt till blank finished product under the condition of 1450 degree.
In technique scheme, described step 1. in, the addition of described HPMC and glycerine is 2.5% ~ 4% of powder dry weight, and the addition of described deionized water is 15% ~ 25% of powder dry weight.
In technique scheme, described step 1. in step c in, the powder preservative film stirred is wrapped, put into 5 DEG C ~ 8 DEG C refrigerator place 48 hours for subsequent use.
In technique scheme, described step 4. in, ceramic blank adopts straight load bearing board to sinter.
In technique scheme, described step 2. in, the optimum range of product thickness is 0.3mm ~ 0.8mm.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the method in the present invention, compared with hydrogel forming method in the past and flow casting molding method, can use common powder body material to produce in the present invention, can High-efficient Production thickness be the thin slice of 0.3mm ~ 1mm, the efficiency of volume production be high.
