The object of the present invention is to provide a kind of preparation method that can overcome the good zirconium jewel go lid of above-mentioned defective, ornamental performance.Its technical scheme is:
Go lid mould is internal mold rubber tube (1), internal mold tube (2), upper and lower mould anchor clamps (3), die clamper (4) in the counterdie, counterdie (5), counterdie rubber tube (6), patrix (7), patrix rubber liner (8), feeding mouth (9) and feeding mouth rubber stopper (10) are formed, with granularity is that 0.5～5 μ m content is that the zirconia mist projection granulating of 3～5mol% stabilized with yttrium oxide is prepared into granulation powder (11), evenly pack into then in the go box mould, at pressure isostatic compaction and pressurize 10～30 minutes under the pressure of 50～300Mpa., zirconium jewel go lid base substrate is made in the demoulding then, fire for 1450～1650 ℃ and burnt till in 3～6 hours, make zirconium jewel go lid through polishing.
The preparation method of described zirconium jewel go lid and go lid mould, internal mold tube (2), counterdie (5) and patrix (7) be make greater than the stainless steel material of 0.5mm by thickness and be evenly equipped with the through hole that many apertures are 1mm.
The preparation method of described zirconium jewel go lid and go lid mould, during compacting, earlier internal mold rubber tube (1) is sleeved on the internal mold tube (2), be set with counterdie rubber tube (6) and counterdie (5) then thereon, by die clamper in the counterdie (4) that counterdie (5) and internal mold tube (2) is fixing, again with patrix (7) liner patrix rubber liner (8), by upper and lower mould anchor clamps (3) upper and lower mould is fixed, by feeding mouth (9) the granulation powder (11) of evenly packing into, then with feeding mouth rubber stopper (10) jam-pack, put into isostatic pressing machine, hydraulic oil is by internal mold tube (2) during pressurization, the through hole that the last many apertures of counterdie (5) and patrix (7) are 1mm affacts internal mold rubber tube (1), counterdie rubber tube (6), patrix rubber liner (8) passes to the granulation powder with pressure.
The present invention compared with prior art, its advantage is:
1, the present invention produces zirconium jewel go lid uniform microstructure, intensity height, global reliability height;
2, it is relatively good that the present invention produces zirconium jewel go lid feel, gloss and color and luster.
