Preparation method of quartz ceramic hollow roller rod for tempered glass heating furnace
The invention discloses a preparation method of a quartz ceramic hollow roller rod for a tempered glass heating furnace, and the specific manufacturing method comprises the following steps: S1, selecting quartz mixed raw materials including silicon nitride and silicon dioxide; S2, grinding the raw materials; S3, preparing colloid slurry: putting the wet-ground slurry, organic colloid, a catalyst, a surfactant and fused quartz mixed raw materials into a stirrer, and uniformly conducting stirring to prepare colloid slurry; S4, conducting forming, specifically building a green body through pressure forming, and adding a sintering aid accounting for 1-5% of the total amount; S5, conducting drying, specifically airing the formed green body in a normal temperature environment for 4-8 hours, and then putting the green body into a drying furnace for drying at the drying temperature of 100-120 DEG C; and S6, conducting sintering, specifically sintering the dried green body under the sintering condition of 1180-1220 DEG C, and keeping the temperature for 2-5 hours to obtain the quartz ceramic hollow roller rod. The treatment process is convenient to operate, the process is simplified, and the product is high in breaking strength, low in apparent porosity and high in densification degree.
本发明公开了一种钢化玻璃加热炉用石英陶瓷空心辊棒的制备方法，具体制作方法包括以下步骤，S1，选取石英混合原料:包括氮化硅和二氧化硅；S2，对原料磨料；S3、胶体料浆的配制：将湿磨后的料浆、有机胶体、催化剂、表面活性剂连同熔融石英混合原料一起放入搅拌机中搅拌均匀，制成胶体料浆；S4、成型，通过压力成型筑成生坯，加入1％‑5％总量占比的烧结助剂；S5、干燥：将成型后的坯体在常温环境下晾干4‑8h，再装进干燥炉中烘干，烘干温度为100‑120℃；S6、烧结：将干燥后的胚体进行烧制，烧成条件为1180‑1220℃，保温2‑5h，即获取石英陶瓷空心辊棒。本发明处理工艺操作方便，工艺简化，产品抗折强度高、低显气孔率，致密化程度高。
