Composite ceramic heating element and preparation method thereof
The invention relates to the technical field of ceramic heating elements, in particular to a composite ceramic heating element and a preparation method thereof.The composite ceramic heating element comprises a heating pipe body, the heating pipe body is formed by at least two layers of self-winding of a composite tape-casting green substrate, and a first insulating layer is arranged on one side of the front face of the composite tape-casting green substrate; a heating circuit and heating circuit electrodes are arranged on the surface of the first insulating layer, the two ends of the heating circuit are connected with the corresponding heating circuit electrodes respectively, a second insulating layer is arranged on the surface of the heating circuit, and the heating circuit is just arranged on the outer circumferential surface of the heating tube body after the composite casting green body substrate is self-wound. A tip protective sleeve is embedded in the end of the heating pipe body, and a flange is sleeved at the other end of the heating pipe body. According to the ceramic heating element, the heating tube body formed by rolling the composite casting green body substrate containing zirconium oxide and aluminum oxide is adopted, so that the ceramic heating element has the advantages of being low in heat conductivity, high in breaking strength, high in temperature rising speed and uniform in heating, and the flange temperature and the dielectric energy loss of the ceramic heating element are reduced.
本发明涉及陶瓷发热体技术领域，具体涉及一种复合陶瓷发热体及其制备方法，包括发热管体，发热管体由复合流延生坯基片自卷绕至少两层而成，复合流延生坯基片正面的一侧设置有第一绝缘层，第一绝缘层的表面设置有发热线路和发热线路电极，发热线路的两端分别与对应的发热线路电极连接，发热线路的表面设置有第二绝缘层，复合流延生坯基片自卷绕后发热线路刚好设置在发热管体的外圆周表面，发热管体的端头嵌设有尖头保护套，发热管体的另一端套设有法兰。本发明的采用含有氧化锆和氧化铝的复合流延生坯基片卷制的发热管体，使得陶瓷发热体具有热导率低、抗折强度高、升温速度快、发热均匀的优点，还降低了法兰温度、陶瓷发热体的介质能量损耗。
