Hopcalite used for gas mask

      The protective object of the CO gas mask is CO. Although CO is a low-toxicity poison, it is colorless and odorless, and it is not easy to arouse people's alertness. People will be poisoned and die after being exposed to 0.2% CO in about 30 minutes. CO often comes from the incomplete combustion of carbonaceous substances. When using coal for heating indoors in winter, special attention should be paid to ventilation to prevent CO poisoning. When a fire occurs, dense smoke, high-concentration CO gas and other harmful gases will be produced, causing great harm to personnel.

      At present, the fire departments of all countries in the world regard the elimination of CO as the main performance index of gas masks. CO-type gas masks use catalytic cartridges. The filter box is filled with a suitable catalyst. When the flue gas containing high concentration of CO passes through, the catalyst filter layer catalyzes the reaction of CO and oxygen in the air to generate carbon dioxide (CO) to achieve the effect of eliminating CO, so as to protect personnel from CO poisoning . The traditional catalyst is hopcalite catalyst, which has been used for nearly one hundred years. It is based on activated carbon as a carrier, and uses a mixture of copper oxide, manganese dioxide and other oxides as an active component. The Hopcalite produced by Xintan has excellent performance, which can remove CO quickly and effectively and has been sold all over the world.
