In China's fire industry, there may not be many people who have heard of tuna, but when it comes to Nanjing Fire Equipment Co., Ltd. (hereinafter referred to as Nanxiao shares), I am afraid that everyone knows that tuna is actually a registered trademark of China Nanjing Fire Company. With the background of state-owned enterprises, the predecessor of tuna is Nanjing Fire Equipment Factory, which was founded in Nanjing in 1958 and is the first batch of state-owned enterprises to produce fire fighting equipment after the founding of New China.
 
Tuna has the special Grade A qualification for fire-fighting facilities engineering design and the first-class qualification for professional contracting of fire-fighting facilities engineering, and is a modern enterprise in the domestic fire-fighting industry assessed by the Development Research Center of the State Council. Nanxiao Technology Center is currently the most advanced fire equipment research and development institutions in China, with dozens of special research laboratories and pilot bases such as fire technology research, many products of tuna have independent intellectual property patents, and its research and development strength in the field of fire protection, the number of heavyweight qualifications is second to none in China.
 
Compared with fire extinguisher products, tuna provides a more well-known overall fire protection solution. Since most of China's fires are caused by cooking oil pan fires, fire products to deal with kitchen fires have a wide range of demand in China, tuna has developed a CMDS type kitchen fire extinguishing device for this purpose, using the saponification reaction of fire extinguishing agent and high-temperature edible oil, a large amount of heat absorption and non-flammable foam covering layer at the same time, to achieve the purpose of fire extinguishing, but this set of equipment is mainly commercial, mainly used in central kitchens, canteens, etc., and is not suitable for home environments.
 
In the civil field, the proportion of domestic families equipped with fire extinguishers is only about 0.1%, and the proportion of more than 40% in developed countries such as Japan is huge, the civil fire extinguisher market is small and less profitable, many fire-fighting equipment manufacturers are mainly commercial products, and the commercial fire extinguisher fire extinguishing agent is filled with a large amount, large and bulky, and is not very suitable for the home environment. Tuna still retains a relatively complete range of household fire extinguisher product lines, including dry powder type, carbon dioxide type, and water-based fire extinguishers, and it is more convenient to buy them online.
 
Water-based fire extinguishers are the representative products of tuna civil fire extinguishers, compared with dry powder fire extinguishers, water-based fire extinguishers have the advantages of no pollution and no residue. The water-based foam fire extinguisher of tuna is based on the characteristics of high specific heat of water, which can reduce the temperature of the fire for the first time, and the large-capacity design of 3L starting installation makes the effective spray time of 15s almost twice that of similar products 8s, effectively preventing and avoiding re-ignition, suitable for standby in warehouses, machine rooms, chemical oil depots and other occasions, and its selling price of 188 yuan is slightly higher than the industry average.
 
In recent years, there is a trend of further popularization in the civilian market, it is worth noting that water-based fire extinguishers are not suitable for extinguishing live equipment fires, and the minimum working environment temperature needs to reach 5 °C, and the maximum can not exceed 55 °C.
