Description
Technical field
The invention belongs to rare earth applied technical fields, and in particular to a kind of new material (yttrium oxide and zirconium oxide composite powder) and
New process (injection moulding).
Background technique
Ganzhou is rare earth kingdom, and Longnan is the township of heavy rare earth, Y in partition2O3Up to 60% or more.
Yttrium oxide and zirconium oxide composite powder are the main raw material(s)s of Ganzhou Jing Huan rare earth Co., Ltd production yttrium zircon ceramic.
Company is stablized using yttriums zircon ceramic series of products, quality such as injection molding technique production fiber stub, clipper pieces.
Currently, stone production material mainly based on plastics, conventional ceramic, jade, glass, shell etc., produces work
Skill is complicated, and product first-time qualification rate is not high；It is big to have the following disadvantages shrinking percentage in 1. plastics molding process, low temperature is variable
It is crisp, it is not wear-resisting, it is easy to aging；2. conventional ceramic crush resistance is poor, complex process；3. cooling velocity is different inside and outside Improving Glass Manufacturing Processes
Generating the huge internal stress being unevenly distributed often causes product to crack；4. jade, sanding and polishing process need to carry out repeatedly to make repeatedly
Industry, and need professional very strong equipment and technology.
It is reported that there is clam Acer stone stone currently on the market, when satisfaction plays chess (it mainly uses function), to chess player with
Come on visual angle, in feel, synthesis aesthetic feeling upper, in tone color of playing chess, so that it is enjoyed；It should be noted: cutting when using and storing
Avoid and is unable in entrance, in order to avoid have the danger of asphyxia；Carefulness uses, broken with anti-collision, has the chess piece of rupture that cannot use；It need to properly protect
Pipe is not easy the place taken in children, in order to avoid eat by mistake；White chessman is easy to make dirty when use, need to be cleaned with suds, before black mole packaging
Once it was coated with one layer of oil, to avoid pollution chessboard, black mole need to cleaned into grease when first used；Black mole is used and can be lost after a long time
It frosts, when not using for a long time, to prevent the paint in chess tank from disseminating Acer stone, the cloth for being stained with edible oil need to be used to wipe,
It can restore gloss.The material and processing disadvantages are: being to hardly result in clam Acer stone because material falls sharply, chess piece saves complexity, cannot
The utilization of enough mass productions, resource is limited.
Chess player has higher quality requirement to product: have good resistant to breakage, stability, use and store it is non-discolouring, haze,
Play continuous and surface gloss uniformity, beauty purification.
