Abstract

本发明公开了一种氮化硅陶瓷吹气管开孔方法，将原料填充至模具内制成吹气管半成品，在吹气管半成品上标记开孔位置，用塑料棒贯穿开孔位置，晾干后进入窑炉，按常规方法烧制即得。本发明与传统技术相比，利用塑料与氮化硅陶瓷熔点的不同，在低温烧制时，塑料棒直接成为碳氧化物或氢氧化物，不会影响氮化硅陶瓷吹气管的性质，从而自行生成开孔。

Description

一种氮化硅陶瓷吹气管开孔方法
技术领域
本发明属于高性能功能陶瓷制造领域，具体涉及一种氮化硅陶瓷吹气管开孔方法。
背景技术
氮化硅陶瓷是一种共价键化合物，基本结构单元为氮化硅四面体，硅原子位于四面体的中心，在其周围有四个氮原子，分别位于四面体的四个顶点，然后以每三个四面体共用一个原子的形式，在三维空间形成连续而又坚固的网络结构。氮化硅热膨胀系数低、导热率高，故其耐热冲击性极佳，而且比钢和工程超耐热合金钢轻得多，因此在耐火材料领域越来越受到青睐。传统氮化硅陶瓷吹气管的开孔方法是待吹气管烧制完成后用金刚钻打孔，缺点显而易见很容易伤害吹气管管体，而且吹气管表面会因为打孔时碎屑的撞击导致不够光滑，影响后续使用。
发明内容
发明目的：本发明的目的在于针对现有技术的不足，提供一种氮化硅陶瓷吹气管开孔方法。
技术方案：为了达到上述发明目的，本发明具体是这样来实现的：一种氮化硅陶瓷吹气管开孔方法，将原料填充至模具内制成吹气管半成品，在吹气管半成品上标记开孔位置，用塑料棒贯穿开孔位置，晾干后进入窑炉，按常规方法烧制即得。
其中，所述塑料棒的长度为3~8cm，直径为1~3cm。
其中，所述窑炉烧制温度不低于1200℃。
其中，所述塑料棒材质为聚乙烯或聚丙烯。
有益效果：本发明与传统技术相比，利用塑料与氮化硅陶瓷熔点的不同，在低温烧制时，塑料棒直接成为碳氧化物或氢氧化物，不会影响氮化硅陶瓷吹气管的性质，从而自行生成开孔。
