Description
Technical field
It the utility model is related to a kind of prosthetic appliance of zirconia ceramics plate surface sand hole.
Background technology
With the rapid development of consumer electronics market, mobile phone productses are except hardware high capacity, vdiverse in function outside the pale of civilization, its outward appearance
Structure material is also frequently weeded out the old and bring forth the new, and it experienced the evolution of plastics, glass, metal.For handset sheathing material
It is required that it is that intensity is high, wearability is good, indeformable, signal passes through the characteristic such as property is good.I.e. by the 5G networks of promotion and application, it is desirable to hand
Machine structure material is in addition to possessing above feature, also with low dielectric constant, to ensure stable signal transmission.And zirconium oxide is made pottery
Ceramic material has that fracture toughness is high (>=8MPam1/2), case hardness height (8.0), good brightness after polishing, fits with human body skin
Answering property waits well Comprehensive Characteristics, it is considered to be following optimal phone structural material.Existing more mobile phone brands are in flagship at present
Ceramic version is released on type, but because zirconia ceramics manufacturing technique requirent is high, process technology difficulty is big, and yields is low to wait limit
System, causes the cost of ceramic mobile phone backboard to remain high, it is difficult to large-scale promotion and application.
For zirconia ceramics product, product is bad mainly sand holes, cut, crackle etc., and wherein cut can pass through
Do over again processing, crackle, which belongs to product rupture, to be scrapped, and sand holes account for more than 70 the percent of defective products sum.Sand holes refer to
Some the larger stomatas being present in zirconia ceramics porcelain body, surface can be shown similar to sand size after polishing
Hole, so referred to as sand holes.Sand holes be by manufacturing process process it is medium-sized into, and can only finishing operation polishing after send out
It is existing, therefore be difficult to eliminate.Once it was found that product can only scrap processing, then material before and can only manually waste, cause to provide
The significant wastage in source, turn into a great problem of puzzlement ceramic industry all the time.Because the ratio of these defective products is too high, cause
The cost of whole zirconia ceramics mobile phone backboard remains high, and seriously limits the commonly used of zirconia ceramics mobile phone backboard,
It can only be applied on a small quantity on high-end product.
Zirconia ceramics is as appearance member, and its surface is by polishing mostly, but surface is easy to after polishing
There is hole not of uniform size, as long as there is a sand hole, product must scrap processing, and this problem seriously restricts the system of ceramic product
Cause this.
