技术领域
本发明涉及陶瓷加工技术领域,尤其是一种耐高温隔热陶瓷加工工艺。
背景技术
陶瓷的发展史是中华文明史的一个重要的组成部分,中国作为四大文明古国之一,为人类社会的进步和发展做出了卓越的贡献,其中陶瓷的发明和发展更具有独特的意义,中国历史上各朝各代有着不同艺术风格和不同技术特点。英文中的“china”既有中国的意思,又有陶瓷的意思,清楚地表明了中国就是“陶瓷的故乡”。早在欧洲人掌握瓷器制造技术一千多年前,汉族就已经制造出很精美的陶瓷。中国是世界上最早应用陶器的国家之一,而中国瓷器因其极高的实用性和艺术性而备受世人的推崇,陶瓷分为工业陶瓷和日用陶瓷,指工业陶瓷应用于各种工业的陶瓷制品。又分为普通陶瓷和特种陶瓷两大类。
目前市面上较多的耐高温大多添加了氧化铝、碳化硅和氮化硅材料来提高其耐高温的能力,单一的耐高温材料已经无法满足高温操作的要求,耐高温陶瓷材料在使用中,加工困难,抗热震性差,不易进行粘结,加工起来不方便。
发明内容

作为本发明的进一步优选方式,制作工艺步骤如下:
a.原料挑选,首先对原料进行检验,去除原料中的杂质,然后进行配料,按照设计好的料方单,将各种原料按分量进行配比;
b.粉碎,将原材料放入研磨机内进行充分的粉碎研磨,粉碎完成后将粉末存放在存放装置内,然后将混合粉末取出并放入搅拌装置内,对其进行充分搅拌均匀,并在搅拌过程中注入水蒸气,保持20ml/min的速度进行均匀送入,整体搅拌温度控制在35-50℃,搅拌10min即可,取出后放入存放装置内;
c.成型,将混合制好的混合物从存放装置内取出,然后缓慢送入冲压模腔中,然后利用液压机配合冲压板对混合物进行冲压,液压机的工作压力为1.2-3.5T,冲压时间为5min,冲压板下行速度为80-120mm/s,成型完成后取出;
d.烧结,将完成冲压成型的材料送入烧结装置内进行加热,烧结装置内部温度升温到达300℃前启动抽真空设备对回火炉抽真空,去除空气;在炉温升至300℃时,启动循环风机,将温度控制在1000-1200℃,持续2-3小时,然后将烧结装置关闭,使烧结完成的陶瓷在烧结装置内部缓慢降温,防止过度降温造成陶瓷表面炸裂,降温持续5小时,降温完成后可讲过陶瓷取出;
e.检验及修边,对加工成型后的陶瓷进行质量检测,表面有裂纹的即为不合格产品,然后将不合格的产品剔除,对合格的产品进行修边,使用修边机来将陶瓷表面的毛刺以及不平整的地方进行打磨,打磨完成后进行分类包装,完成加工。
作为本发明的进一步优选方式,步骤b中,混合加入水后,利用搅拌设备进行搅拌,在搅拌的过程中加入2份量的水玻璃。
作为本发明的进一步优选方式,步骤b中,对原料进行分开粉碎,粉碎完成后放置在一起。
作为本发明的进一步优选方式,步骤c中,若需要对工件进行冲孔,可以配合冲孔机进行冲孔。
本发明所达到的有益效果是:本发明是在陶瓷的原料内添加了菱镁石和氮化硼可以增加陶瓷成型后的耐高温程度,防止在高温环境下工作出现开裂的现象,在原料内添加了碳酸钙可以增加陶瓷的硬度和耐磨程度,避免在使用中发生过度磨损而造成损坏,在搅拌的过程中添加了水玻璃,可以使原料粉末更容易的粘接在一起,提高了陶瓷的结构强度,增加了使用寿命。
