Problems solved by technology

All urban buses in our country are equipped with portable dry powder fire extinguishers, but fire accidents occur frequently in buses, and the equipped fire extinguishers cannot function, causing major accidents of vehicle crashes and fatalities, which further proves this problem
[0011] Therefore, the problem existing in the prior art is: the fire extinguisher used on the public transport vehicle is inconvenient to take, the operation is complicated, and the fire extinguishing effect is poor.

preparation example Construction

[0037] The preparation method of liquid fire extinguishing agent of the present invention is as follows:

[0038] 1. According to the composition and the ratio of parts by weight, weigh each component with an electronic scale;

[0039] 2. Heat the pure water to 30℃~40℃;

[0040] 3. Add surfactant and stir for 90 minutes at a speed of 30 rpm;

[0041] 4. Add carbonamide, ammonium bicarbonate, inorganic salts, sodium bicarbonate, and alcohol-resistant foam liquid, and stir at a speed of 30 rpm for 180 minutes to obtain a liquid fire extinguishing agent for filling.

[0042] The above-mentioned liquid fire extinguishing agent is filled into a fragile plastic container with conventional equipment and methods to obtain the water-based throwing fire extinguisher of the present invention.

Embodiment 1

[0044] The liquid fire extinguishing agent consists of 20 parts by weight of carbonamide, 15 parts of ammonium bicarbonate, 5 parts of inorganic salt, 30 parts of alcohol-resistant foam liquid, 2 parts of surfactant, 7 parts of sodium bicarbonate, and 546 parts of purified water.

[0045] The preparation method of the liquid fire extinguishing agent in this example is as follows: according to the composition and the ratio of parts by weight, weigh each component with an electronic scale; heat the purified water to 30°C-40°C; Stir for 90 minutes; add carbonamide, ammonium bicarbonate, inorganic salts, sodium bicarbonate, and alcohol-resistant foam liquid, and stir for 180 minutes at a speed of 30 rpm to obtain a liquid fire extinguishing agent for filling. The above-mentioned liquid fire extinguishing agent is filled into a fragile plastic container with conventional equipment and methods to obtain the water-based throwing fire extinguisher of the present invention. The formula...

Embodiment 2～8

[0047] The formulations and experimental results of Examples 2-8 are shown in Table 1, and the preparation method and experimental method are the same as in Example 1.

[0048] Table 1 The proportion of liquid fire extinguishing agent and the results of fire extinguishing experiment

[0049]

[0050] As can be seen from Table 1, the water-based throwing fire extinguisher of the present invention has a good fire extinguishing effect.

[0051] And because the operation is simple, the support is made of engineering plastic material, the support is fixed on the compartment by two holes with screws, and the fire extinguisher is hung on the compartment wall by the support. The purpose of the support being designed as a card structure is that when a fire breaks out in the compartment, the fire extinguisher can be pulled out from the front or pulled out from above to put out the fire conveniently and quickly in case of emergency. Especially suitable for use on public transport vehic...

Abstract

The invention discloses a liquid extinguishing agent and a water-based expendable fire extinguisher. The liquid extinguishing agent is prepared from the following components in parts by weight: 20-30 parts of carbamide, 15-30 parts of ammonium hydrogen carbonate, 5-10 parts of inorganic salt, 15-30 parts of anti-solving foam concentrate, 2-4 parts of a surfactant, 7-15 parts of sodium hydrogen carbonate, 546-491 parts of purified water. The water-based expendable fire extinguisher prepared by the liquid extinguishing agent comprises a fragile plastic container and the liquid extinguishing agent which is filled in the container. The fire extinguisher disclosed by the invention is simple to operate, good in fire-distinguishing effect and suitable for being used on public transport vehicles.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, in particular to a liquid fire extinguishing agent with good fire extinguishing effect and a water-based throwing fire extinguisher which is easy to hang, convenient to take and quickly extinguish fire, and is especially suitable for public transport vehicles. Background technique [0002] Existing public transport vehicles (comprising buses and subways) are all equipped with fire extinguishers, and mostly are portable dry powder fire extinguishers. This fire extinguisher is mainly composed of a cylinder, a bottle head valve, a spray hose (nozzle) and a dry powder fire extinguishing agent. Dry powder fire extinguishing agents are generally divided into two categories: BC dry powder fire extinguishing agents and ABC dry powder fire extinguishing agents. BC dry powder fire extinguishing agent is sodium bicarbonate, ABC dry powder fire extinguishing agent is ammonium phosphate. The...
