The ceramic piece heating element has poor rigidity and is easily damaged during use or production. Ceramics have low thermal conductivity, resulting in uneven heat.
另一种在圆形陶瓷棒内印刷发热材料，或是在印有发热丝的陶瓷棒外面套不锈钢管，当发热丝通电后发热，热量传导到不锈钢管后再传导到外面需要加热的物体。陶瓷棒发热体由于表面积小，热量向外传导慢，如果在***隔一层不锈钢管则外传导就会更慢。Another type of heating material is printed in a circular ceramic rod, or a stainless steel tube is placed on the outside of a ceramic rod printed with a heating wire. When the heating wire is energized, heat is generated, and the heat is conducted to the stainless steel tube and then conducted to an object to be heated outside. Due to the small surface area of the ceramic rod heating element, the heat conduction to the outside is slow. If a stainless steel tube is placed on the outside, the conduction will be slower.
