Method for manufacturing zero-power ceramic chip of PTC (Positive Temperature Coefficient) heater
The invention discloses a method for manufacturing a zero-power ceramic chip of a PTC (Positive Temperature Coefficient) heater, which comprises the following steps of: grinding all components in the material of the zero-power ceramic chip of the PTC heater into powder through a ball mill, mixing to form mixed powder, and adding water as a medium; adding PVA particles or a PVA solvent as a binder, carrying out ball milling on the mixed powder, water and the binder for a preset time at the same time, and then carrying out granulation to obtain mixed powdery particles; the mixed powdery particles are pressed into a biscuit with a preset size, and the biscuit is placed in an air atmosphere with a preset temperature to be fully sintered into the compact ceramic. The zero-power ceramic chip of the PTC heater is made of waste recycled materials or sludge of PTC production enterprises. The waste treatment cost can be reduced, and the method is simple to operate, easy to control, low in cost and very suitable for industrial implementation.
本发明公开了一种PTC加热器零功率陶瓷片的制作方法，包括以下步骤：将所述PTC加热器零功率陶瓷片的材料中各组分通过球磨子研磨成粉体混合，形成混合粉料，同时添加水作为介质；添加PVA颗粒或PVA溶剂作为粘结剂，同时球磨所述混合粉体、水和所述粘结剂一预设时间后进行造粒，得到混合粉末状颗粒物；将所述混合粉末状颗粒物压制成预设尺寸的素坯，所述素坯置于预设温度的空气气氛中使其充分烧结为致密陶瓷。所述PTC加热器零功率陶瓷片的材料来自PTC生产企业的废弃回收料或污泥。本发明可以降低废料处理的成本，方法操作简单，易于控制，成本低廉，非常适合产业化实施。
