耐酸碱抗氧化镍铬电热丝0.3mm

电热合金扁带工作原理是指电流在通过电热合金导体后，电流会产生一定的热量并被导体传递出来。电热合金本身就是金属导体，在通电后即会散发出热量、提供热能。我厂专业生产电热合金材料，主要有镍铬电热带及铁铬铝电热带两大系列，发热扁带可以根据客户的自行设计的产品图纸和技术要求或来样进行生产，薄片状电热带可塑性高且可蚀刻成型，其形状可以为有U型，波浪型，M型等异型。

电热合金扁带的使用方式
电热合金扁带在使用前进行预氧化处理，其方法是将安装完毕的电热合金元件，在干燥的空气中通电加热到低于合金允许使用温度100-200度，保温5-10小时，然后随炉缓慢冷却既可。
电热合金扁带的用途
该产品广泛应用于各种工业电炉及民用电加热设备如小型电炉、烘烤箱、马弗炉、采暖空调设备、封口机、真空包装机各类烘电热管及家用电器等。
