热效应式载体催化元件是利用铂钯金属催化剂浸渍在具有多孔,耐高温、又有一定强度的、特种配方的活性氧化铝载体上,它有对煤矿瓦斯的低温催化燃烧特性,我们用测量加热丝电阻变化或元件周围温度场的变化来指示瓦斯浓度。载体催化元件的制造是在螺旋卷白金丝上复涂由活性氧化铝和销酸铝溶液配制的复 Thermal effect of the catalytic element carrier is the use of platinum palladium metal catalyst impregnated in porous, high temperature, but also a certain strength of the activated alumina carrier formulations, it has a low-temperature catalytic combustion of coal gas methane, we measure the heating wire Changes in resistance or temperature changes around the component to indicate gas concentration. The carrier catalytic element is manufactured by overcoating a spirally wound white gold wire with a solution of activated alumina and an aluminum titanate solution
