摘　　要：PTC材料是正电阻温度系数很大的半导体材料，可以用于制作定温发热器件。用PTC材料制成的定温发热器件所具有的特殊性质，附合解吸除氧器的反应器中对除氧反应剂加热的要求。将PTC加热元件用于解吸除氧器，可以得到良好的自动定温加热和节能效果。Matcrial PTC is a kind of semiconductor with very high positive resistance-temperature coefflcient. It can be used for making constant-temperatue heating elcment.The constant-temperature heating element, made of material PTC possess special per-formance, Which can meet the requirement for heating deoxdizing angent inside the reactorof desulve-absorption deoxidizer.By making use of heating element for desulve-absorption deoxidizer, the better resultsof autumahc constant-temperature heating and energy-saving can be obtaincle
