Manufacturing technology of multicolor zirconia bracket
The invention discloses a manufacturing technology of a multicolor zirconia bracket. The technology comprises the following steps: (1) preparing a powder: taking zirconia as a raw material, and grinding the zirconia into particles with the diameter of 600 +/- 20 nm; (2) mixing: mixing the zirconia particles with toned metal oxide to obtain a mixed powder; (3) sanding and drying: sanding the mixedpowder into particles with the diameter of 60-600 nm, and drying the particles; (4) internally mixing: adding PE and PP into the mixed powder, and performing internal mixing to obtain blocky irregularsolid particles; (5) performing injection molding: adding the irregular solid particles into an injection molding machine, and performing injection molding to obtain a bracket; and (6) sintering thebracket. The zirconia is used as the raw material, and is respectively mixed with erbium oxide, cobalt oxide, magnesium oxide, praseodymium oxide and the like, and the obtained mixture is sanded, internally mixed and sintered to form brackets with various colors, so that a user can individually select the color of the bracket, and the multicolor zirconia bracket has the advantages of good aesthetic appearance, high strength, good compactness and low possibility of falling off.
本发明公开了氧化锆多彩托槽制造工艺，包括如下步骤：（1）粉体制备：以氧化锆为原材料，将氧化锆研磨成直径为600nm±20nm状颗粒；（2）混合：氧化锆颗粒与调色的金属氧化物混合，得到混合粉体；（3）砂磨并干燥：将混合粉体砂磨成直径为60～600nm的颗粒并干燥；（4）密炼：混合粉体中加入PE和PP进行密炼，得到块状不规则固体颗粒；（5）注塑成型:将不规则固体颗粒加入至注塑机中注射成型，得到托槽；（6）烧结。本发明具有以下优点和效果：以氧化锆作为原材料，分别与氧化铒、氧化钴、氧化镁、氧化镨等混合、砂磨、密炼、烧结成各色托槽，使用者可个性化地选择托槽颜色，具有美学外观较好、强度较高、致密性较好、不易脱落的效果。
