Abstract

The invention discloses a gas producing agent for non-pressure-storing fire extinguishing apparatus and a preparation method and belongs to the technical field of fire extinguishing agents. The gas producing agent is prepared from 60%-73% of an oxidizing agent, 18%-28% of a reducing agent, 2%-4% of a fuel regulator, 0%-2% of a processing aid and 5%-10% of a binder. The preparation method of the gas producing agent comprises the following steps: (1) the components are weighed in the mass percentage designated in the formula; (2) the weighed components except the binder are mixed in a mixer for 15 min; (3) the binder is dissolved in an ethanol solvent accounting for 40% of the total agent weight; (4) the binder solution is added to the mixer, the mixture is mixed for 30 min, agent balls are prepared and fed into a granulator and sieved by a 30-mesh sieve for granulation, the agent granules are dried and pressed, and agent grains are obtained. The gas producing agent has the advantages of wide component raw materials, low cost, low burning temperature and non-toxic and harmless burning product.

Description

technical field [0001] The invention relates to a gas-generating medicament and a preparation method, in particular to a non-storage-pressure fire extinguishing device and a gas-generating medicament and a preparation method. Background technique [0002] At present, ultrafine dry powder fire extinguishing devices are divided into two categories: [0003] The first is the pressure storage suspension type, which is driven by nitrogen gas, and the storage pressure is 1.2Mpa. There is a pressure display on each device. During daily maintenance, the operation status of the fire extinguishing device can be visually checked. This device is composed of a tank body and a nozzle. There are temperature-sensitive glass bulbs installed on it, and the configuration is based on the daily temperature at the installation site plus 30 degrees. The temperature of the nozzle generally includes: 57, 68, 79, 93, 141, etc. The advantage is that the fire extinguishing agent is sprayed evenly and f...
