Silicon carbide injection molding process
The invention discloses a silicon carbide injection molding process, and belongs to the technical field of silicon carbide injection molding, and the technical scheme is characterized in that the silicon carbide injection molding process comprises the following steps: S1, carrying out ball milling, drying, crushing and sieving on raw materials to obtain powder I; s2, performing cold isostatic pressing, crushing and sieving on the powder I to obtain powder II; s3, the powder II and an adhesive are subjected to banburying, cooling, crushing and sieving, and feeding particles are obtained; s4, performing injection molding on the feeding particles to obtain a ceramic green body; s5, dewaxing and soaking the ceramic green body to obtain a green body; and S6, sintering the green body to obtain the product. According to the silicon carbide injection molding method, through mutual cooperation of the working procedures of powder preparation, cold molding, internal mixing feeding, injection molding, dewaxing degreasing, sintering and the like, a product with the injection density being 3.13-3.17 g/cm < 3 > and the bending strength being larger than or equal to 390 MPa can be obtained; by means of the process, products with higher quality can be obtained, and the requirements of more high-requirement application scenes can be met.
本发明公开了一种碳化硅注塑成型工艺，属于碳化硅注塑成型技术领域，其技术方案要点是，包括如下步骤：S1、原料经过球磨、烘干、破碎过筛得到粉体Ⅰ；S2、使粉体Ⅰ经过冷等静压、破碎、过筛，获得粉体Ⅱ；S3、粉体Ⅱ和粘接剂经过密炼、冷却破碎、过筛获得喂料颗粒；S4、喂料颗粒通过注射成型获得陶瓷生坯；S5、将陶瓷生坯脱蜡浸泡获得坯体；S6、坯体烧结后获得产品。本发明的碳化硅注塑成型通过制备粉料、冷等成型、密炼喂料、注射成型、排蜡脱脂、烧结等工序的相互配合，能够获得注塑密度为3.13～3.17g/cm3、抗弯强度≥390MPa的产品；通过该工艺能够获得更高品质的产品，满足更多高要求应用场景的需求。
