/ Manufacture of dust/gas mask packed with activated carbon fiber carbon fiber for removal of toxic and harmful gases

摘要

PURPOSE: Provided is a multi-functional handy mask containing active carboneous fiber for blocking toxins and dust which has improved purification efficiency and can be recycled and environment-friendly used for an elongated time. CONSTITUTION: The mask comprises a multi-functional cartridge and a silicone/synthetic rubber body. The multi-functional cartridge has a surface filter(4) for blocking dust, an active carboneous fiber filter(5), a functional filter. The surface filter for blocking dust is subjected to water repellent and oil repellent treatment and thereby, has effects to block water and oil. This allows the mask to be usable and show excellent dust-blocking effects in a moisture or foggy working place. The active carboneous fiber includes a woven fabric of pure active carboneous fiber/active carboneous fiber, or a woven fabric of metal-added active carboneous fiber/active carboneous fiber and can effectively remove polar odor substances. The functional filter(6) acts as a supplement filter. The silicone synthetic rubber is constructed to fix the face of a user so that the user may have comfort feelings and contaminated air is prevented from flowing in.
