Precision machining process and formula for large-scale structural ceramic
The invention discloses a large-scale structural ceramic precision machining process and formula, and the large-scale structural ceramic precision machining formula comprises the following preparation raw materials in parts by weight: 47-65 parts of a mixture, 3-7 parts of a dispersing agent, 2-5 parts of an active agent, 6-9 parts of a binding agent, 1-5 parts of a catalyst, 7-13 parts of an auxiliary agent, 8-11 parts of a grinding agent and 2-6 parts of a grinding material. The surface charge density is improved, Van der Waals attractive force among particles is overcome, the active agent is added to change the characteristics of the powder crystal, it is guaranteed that the formed ball blank has enough strength to change the characteristics of the powder crystal, and the forming rate and the forming strength are improved; in the sintering process, a proper amount of binding agent is added, a ceramic ball blank is more compact, air holes or cracks in the blank can be closed and disappear under the action of nitrogen pressure increasing along with nitrogen pressure increasing, the internal structure is more compact, and the mechanical performance is obviously improved; and in the machining process of the ceramic ball, the ceramic bearing is precisely manufactured, so that the service life is prolonged, and the quality is improved.
本发明公开了一种大型结构陶瓷精密加工工艺及配方,其制备原料,以重量份计,包括混合物47‑65份、分散剂3‑7份、活性剂2‑5份、结合剂6‑9份、催化剂1‑5份、助剂7‑13份、研磨剂8‑11份和磨料2‑6份,本发明在陶瓷球制备过程中加入分散剂,使其表面电荷密度提高,克服颗粒间的范德华吸引力,加入活性剂改变粉末晶体的特性,保证成型的球坯有足够的强度改变粉末晶体的特性,提高成型率和成型强度;在烧结过程中,对其进行加入适量的结合剂,对陶瓷球毛坯会更加致密,随着氮气压力的提高,毛坯内部气孔或者裂缝在氮气压力提升的作用下会闭合消失,内部结构更加紧凑,机械性能得到明显提高;且在陶瓷球的加工过程中,对陶瓷轴承进行精密制作加固了使用寿命和质量。
