陶瓷加热器（TY-004型）主要用于塑料工业注塑机、挤出机和吹塑机的加热，同时也可用于反应釜、熔体管道等化工领域的加热。
产品结构
陶瓷加热器(TY-004型）采用Ni80Cr20电阻丝插入陶瓷内孔，整个加热体柔软可塑，升温迅速，加热均匀，节能及较长的使用寿命。金属外壳采用不锈钢板或镀铝钢板制作。
技术参数
陶瓷加热器(TY-004型）工作温度可达760℃，功率密度可高至8w/cm2。陶瓷加热圈的直径为40mm，直径大于600mm时，应分成2-8个弧段加热，采用压力弹簧夹紧。加热器的宽度为18mm，以7.5mm为进阶(18、25.5、33、40.5、48mm……)宽度不应大于500mm，加热体的厚度为12mm，如需加保温层，加热体的厚度会根据保温层厚度增大，请考虑安装空间。
电源接线方式
1.插头式接线(*大20A)；
2.接线盒式接线（可多相固定连接）；
3.高温线引出式接线（屏蔽耐热纯镍导线）。
It is mainly applied to heating the plastic injection molding machine, extruding machine and blowing machine. Meantime, it also can be used to heat reaction kettle, melt pipe, etc in chemical industry.
Structure
Ni80Cr20 resistance wire is inserted into ceramic inner hole. The whole heating body is soft & mouldable, energy-saving and durable. Furthermore, it is heated up quickly and evenly. The metal shell is made of stainless steel plate or galvanized steel plate.
Technical Parameter
The working temperature can be up to 760℃ and the power density 8w/cm2. The minimum diameter of ceramic heating ring is 40mm.
When the diameter is larger than 600mm, the ring, clamped by pressure spring, should be separated int0 2-8 segmental arc to be heated. On the other hand, the minimum width of the heater is 18mm and the maximum width of that should not be more than 500mm, increasing by 7.5mm (1 8,25.5,33,40.5,48mm...). The thickness of the heating body is 12mm. If adding thermal insulation layer, the thickness of the heating body increases accordingly. Please take installation space into consideration.
