Description

一种色选机用氧化锆陶瓷喷嘴及其制备方法
技术领域
本发明属于材料领域,具体涉及一种色选机用氧化锆陶瓷喷嘴及其制备方法。
背景技术
目前陶瓷喷砂嘴、喷油嘴等喷嘴多采用碳化硅、碳化硼或者氧化铝等陶瓷材料制造,制造技术采用热压法或者无压烧结方法。以往常用的材质为二氧化硅材质和纯氮化硼材质喷嘴,二氧化硅材质的喷嘴由于其硬度较高,加工性能较差,只能适用于宽度较小的窄带材的生产。而纯氮化硼材质的喷嘴,加工性能很好,虽然散热效果较好(导热性能好),但抗热冲击能力以及韧性都较弱,使用一段时间后,很快就会出现喷口变形、喷道被熔融液体冲击成流沟,造成喷射体沉积在基材上的厚度不均匀。
发明内容
本发明的目的是提供一种色选机用氧化锆陶瓷喷嘴及其制备方法。
为实现上述目的,本发明采用以下技术方案:
一种色选机用氧化锆陶瓷喷嘴,它是由下述重量份的原料组成的:

所述的催化剂为浓度为85-90%的盐酸。
一种色选机用氧化锆陶瓷喷嘴的制备方法,包括以下步骤:
(1)取高岭土,在700-800℃下煅烧1-2小时,冷却至常温,磨成细粉,加入到其重量20-30倍的无水甲醇中,搅拌均匀,加入硅烷偶联剂kh560,送入到恒温水浴中,在75-80℃下保温搅拌1-2小时,出料冷却,得硅烷分散液;
(2)取催化剂,加入到上述硅烷分散液中,搅拌均匀,送入到反应釜中,在55-60℃下保温搅拌13-15小时,出料冷却,得改性分散液;
(3)取二乙烯三胺,加入到其重量10-15的无水甲醇中,搅拌均匀,加入氮化硼,超声30-40分钟,得氮化硼分散液;
(4)取氧化镁、碳酸钠混合,加入到混合料重量30-37倍的去离子水中,超声5-19分钟,得氧化镁分散液;
(5)取上述改性分散液、氮化硼分散液混合,搅拌均匀,加入正硅酸乙酯,升高温度为150-160℃,保温搅拌100-110分钟,加入上述氧化镁分散液,搅拌至常温,搅拌4-6小时,过滤,将沉淀水洗,真空干燥,得预混填料;
(6)取上述预混填料,与氧化锆混合,送入到球磨机中,球磨至细度为250-270目筛;
(7)将上述晒料送入到模具中压制成型,出模得胚体;
(8)将胚体进行烧结处理,胚体先在20-26min内升温至450-460℃,保温2-3小时,再按10-15℃/min升温至1500-1600℃,保温12-13小时后取出,自然冷却,即得所述色选机用氧化锆陶瓷喷嘴。
步骤(5)中所述的真空干燥温度为1000-1100℃,干燥时间为80-100分钟。
步骤(6)中的压制成型条件为:压力机设定温度为295-300℃,在17-20MPa条件下保压20-25min。
本发明的优点:
本发明的陶瓷喷嘴实现氧化锆、二氧化硅、氮化硼、氧化镁等多种原料的有效复合,具有很好的结合稳定性强度,提高了传统陶瓷喷嘴的硬度和耐腐蚀性能,本发明改善了传统二氧化硅硬度高、加工性差的缺陷,成品的稳定性高,综合性能优越,本发明采用有机方法改性,可以提高烧结的致密强度,增强成品的力学性能。
