Tianguang full name Tianguang Zhongmao, is China's earliest fire equipment production qualification, is also the first in the A-share listed fire protection enterprises, in the industry concentration is low, industry brand scattered in the domestic fire market, the establishment of 1986 Tianguang is fully qualified to be called the old brand.
 
In addition to simple fire extinguishers and other equipment, it also has a first-class qualification for professional contracting of fire protection facilities engineering, which can provide a complete set of fire protection solutions including product supply, fire engineering design, installation and maintenance for various industries.
 
As one of the largest fire-fighting equipment manufacturers in China, Tianguang's scale and technical strength should not be underestimated, it can produce 11 categories and more than 100 varieties, and is one of the enterprises with the most varieties and the strongest supporting capacity in China's fire protection industry, with an operating income of 287 million yuan in the first half of 2018, which is one of the few in the fire protection industry.
 
In terms of technology research and development, Tianguang has obtained nearly 40 valid patent authorizations, of which one invention patent has won the "National Excellent Patent Award", and has participated in the drafting of national and industry standards for fire protection products for many times, and its products have been used in the Bird's Nest, Water Cube and the Great Hall of the People.
 
At present, the Tianguang fire extinguishers sold by e-commerce are all dry powder type, and the dry powder fire extinguishers produced by Tianguang use compressed carbon dioxide or nitrogen as a power source to spray dry powder, which undergoes a chemical reaction on the surface of combustibles, and forms a glass-like covering layer under the action of high temperature to isolate oxygen to achieve the purpose of extinguishing fires. Because the pressure in the gas tank will reach more than 1.2MPa when working, Tianguang's high-strength bottle body and base have been thickened, which has the characteristics of corrosion resistance and rust resistance while resisting high pressure, and the safety is more guaranteed in the perennial standby state.
 
Dry chemical fire extinguishers can extinguish fires caused by the combustion of solid, liquid, gas, and live objects at the same time, and the MFZ/ABC series fire extinguishers are enough for daily household use. MFZ/ABC series fire extinguisher, as the representative of Tianguang's dry powder fire extinguisher, strictly follows the requirements of the national standard GB4351.3-2005, the minimum limited spray time can reach 8s, and the minimum limited spray distance of 1kg dry powder fire extinguisher is 3.5m, which is 0.5m farther than the specified standard. MFZ/ABC is available in four different sizes, among which the smallest volume of 1Kg is the largest, and the tank height is only 25cm, which is very space-saving for storage and suitable for on-board backup.
 
It should be noted that the disadvantage of dry powder fire extinguisher is dust pollution, the human body is easy to cause secondary injury after fire after inadvertent inhalation, and it is also very troublesome to clean up dry powder fire extinguisher.
