Description
Technical field
The invention belongs to mobile phone backplane technology field, and in particular to a kind of zirconia ceramics mobile phone backboard and its preparation side
Method.
Background technology
At present, the material selection of phone housing, no matter outward appearance, feel to mobile phone in itself, still in the fabrication process
Technique, suffers from very big influence.The appearance design of mobile phone is perhaps very diversified, but nearly all uses plastic material.And near
Nian Lai, metal, glass even leather, sapphire can use on mobile phone, it is become high-end, fineness, meet different people
Aesthetic requirement.
However, the above material also has shortcoming, such as：First, plastics.Texture is not good：Compared to overflowing that metal, glass are produced
Valency sense, plastic casing is comparatively more dull, even if manufacturer is continuously added the different designs element such as decorative pattern, simulated leather, but just
It is still more inferior for feel.Radiating effect is general：Makrolon be comparatively heat non-conductor, it means that
Heat possibly can not disperse in time, it is possible to can influence the operational effect of mobile phone.Second, metal；Heat causes feel uncomfortable：Though
The radiating effect of right mobile phone with metal shell is more preferable, but this is also double-edged sword, because the thermal conductivity of metal may allow mobile phone to become
It must scald one's hand, influence feel.Easily scratch：Current mobile phone metal shell is handled usually using anodic oxidation and polychrome spray painting, if hair
Raw physical impacts, are very easy to paint and oxidation, reduce glossiness, influence attractive in appearance；Simultaneously as the hardness of aluminium alloy is softer,
Collide with and easily leave a trace.3rd, glass.It is fragile：Obviously, glass is very easy to smash, even enhanced type glass
Glass.It fact proved, mobile phone component the most fragile is had become using the handset touch panel of glass panel.The limitation of design：
Because glass is often (although flexible, curve screens have occurred) of plane, for main flow, glass material is not as modeling
Material, metal are flexible like that, it is possible to achieve more design forms.4th, leather.The potential problems of leather：Using a period of time
Afterwards, leather obviously can easily wear, and influence aesthetic property.In addition, actually leather bonnet nexine be plastics, so its shortcoming also with
Plastic casing is consistent.
