Aerosol fire extinguisher uses high-efficiency solid fire extinguishing composition to generate gas heat and power by using gas generating agent, so that the fire-extinguishing particle generating agent can decompose a large number of fire-extinguishing substances, which can reduce the gas temperature and spray out with the gas to achieve the purpose of high-efficiency fire-fighting. "Generally speaking, the time from fire to uncontrollable is only 30 seconds. After repeated tests, our products can quickly suppress the initial fire within a few seconds." Tianyu security R & D personnel said.
