Embodiment 1

[0028] as attached figure 1 As shown, a method for manufacturing a zirconia ceramic mobile phone back cover, the zirconia ceramic mobile phone back cover is a thin-walled device, and the injection molding method is used to produce the zirconia ceramic mobile phone back cover, with zirconia powder containing a stabilizer as the main body , mix the zirconia powder and the organic carrier according to the weight ratio of 100:10-30; obtain the injection molding material after banburying, and then use the injection molding process to make the zirconia ceramic mobile phone back cover body 1, and use the injection molding process at the same time Make the support mold 2 and cover plate 3 with the same injection material, then put the zirconia ceramic mobile phone back cover body 1 into the support mold 2, and then cover the cover plate 3 on the zirconia ceramic mobile phone back cover blank Body 1, and then carry out the secondary degreasing treatment of soaking oil and heating degr...

Embodiment 2

[0042] The basic method of the second embodiment is the same as that of the first embodiment, a zirconia ceramic thin-walled plate, and the manufacturing method of the zirconia ceramic thin-walled plate is a zirconia ceramic thin-walled device produced by an injection molding method to contain a stabilizer The zirconia powder is the main body, and the zirconia powder and the organic carrier are mixed in a weight ratio of 100:10-30; the injection molding material is obtained after banburying, and then the green body is made by the injection molding process, and the support is made by the injection molding process The mold and cover plate, then put the zirconia ceramic thin-walled plate blank into the support mold, and then cover the cover plate on the zirconia ceramic thin-walled plate blank, and then carry out the secondary degreasing of soaking oil and heating degreasing together treatment, and finally a zirconia ceramic thin-walled plate with no deformation and high performan...

Abstract

A manufacturing method of a zirconia ceramic large-scale thin-wall device is disclosed. After compression moulding of a zirconia ceramic thin-wall device and before sintering in a furnace, the zirconia ceramic thin-wall device is placed onto a supporting mould with its inner surface consistent with the appearance of the zirconia ceramic thin-wall device and with thickness being greater than thickness of the zirconia ceramic thin-wall device; then, the zirconia ceramic thin-wall device is covered with a cover plate and the zirconia ceramic thin-wall device fits closely between the supporting mould and the cover plate; and finally, the zirconia ceramic thin-wall device, the supporting mould and the cover plate together undergo oil immersion, degreasing and furnace-sintering so as to prevent the zirconia ceramic thin-wall device from deforming.

Description

technical field [0001] The invention relates to a method for manufacturing zirconia ceramics, in particular to a method for manufacturing large-scale thin-walled zirconia ceramic devices, which are mainly used for manufacturing large-scale thin-walled devices such as mobile phone cover plates, and belong to the technical field of industrial ceramic manufacturing. Background technique: [0002] Zirconia ceramics (ZrO 2 Ceramics) have excellent properties such as high melting point and boiling point, high hardness, insulator at room temperature, and electrical conductivity at high temperature. So now it is more and more widely used. Among them, in terms of structural ceramics, zirconia ceramics are widely used because of their high toughness, high bending strength and high wear resistance, excellent heat insulation performance, and thermal expansion coefficient close to steel. Applied in the field of structural ceramics. Mainly include: Y-TZP grinding balls, dispersing and ...
