贮气瓶式干粉灭火器的驱动气体,通常是二氧化碳,其充装量在产品标准中没有规定,只要满足标准中规定的喷射和灭火性能即可。那么,同样规格的干粉灭火器,二氧化碳的充装量是多好还是少好呢?在六、七十年代,由于对干粉灭火的原理研究得不很透彻,以至从技术人员到工人,乃至商业部门的业务、销售人员,多年来都认为充气多总比充气少好。其理由是,二氧化碳不仅是驱动气体,而且是灭火剂。以内装8公斤干粉的 Gas cylinder dry powder fire extinguisher driving gas, usually carbon dioxide, the filling amount is not specified in the product standards, as long as the standard to meet the injection and fire extinguishing performance can be. So, the same specifications of dry powder fire extinguishers, carbon dioxide filling quantity is good or bad? In the sixties and seventies, due to the principle of dry powder fire research is not very thorough, and even from technicians to workers, and even the commercial sector Business, sales staff, over the years that inflatable more than inflatable better. The reason is that carbon dioxide is not only a driving gas, but also an extinguishing agent. To built 8 kg of dry powder
