Description

technical field [0001] The invention belongs to the field of catalytic heating, and in particular relates to a gas infrared catalytic fiber layer and a preparation method thereof. Background technique [0002] At present, the infrared radiation heating technology commonly used at home and abroad basically uses electric heating as the heating energy. Even the most advanced electric heating high infrared radiation technology in the world should have high investment costs, high management and maintenance requirements, and high operating costs. Short life, high energy consumption, and the high-infrared quartz glass tube is easily damaged, and the circuit is prone to various safety hazards such as wire leakage, short circuit, etc., so that users who originally used electric infrared radiation heating technology cannot use it safely and safely. As an industrial application, it can no longer completely pass the use requirements and standards stipulated in my country's new safety stan...
