The third generation aerosol (type S) mainly uses strontium salt as oxidant. Unlike the second-generation potassium salt (K-type) aerosol, strontium ions do not absorb moisture, form conductive solutions, and do not damage electrical equipment. S-type aerosol automatic fire extinguishing products were first independently developed by Xi Anjianrui Chemical Co., Ltd. (now Shaanxi Jianrui Fire Fighting Co., Ltd.) in the early 20th century.
In 200 1 year, China Mobile Communications Group Company selected its strontium salt aerosol (S-type aerosol automatic fire extinguishing device) to protect its communication base station and other places equipped with precision electronic equipment.
At present, strontium salt aerosol products have been applied in thousands of engineering projects, and the third generation aerosol has been more and more accepted by users.
