Method for preparing carrier catalytic element for gas detection in coal mine

摘要: This invention relates to a making method of detecting carrier catalysis element coal firedamp, which is characterized by the following: rolling platinum wire around thin mill; dipping dense hydrochloric acid erase corrosion welding clean on shelf element; brushing with carriers; heating electricity until white carriers appearing heating. The black produced then heated electricity, doesn't stop sintered. We can obtain matching and activation disposal elements, are disposed aging platform in sinter hood.
