Fire equipment classification
Fire equipment classification Fire extinguishing 1. Fire extinguishing appliances include: carbon dioxide fire extinguisher, 1211 fire extinguisher, dry powder fire extinguisher, acid foam fire extinguisher, carbon tetrachloride fire extinguisher, fire extinguisher hanger, mechanical foam fire extinguisher, water fire extinguisher, and other fire extinguishing appliances. Common fire-fighting equipment 2, fire hydrants include indoor fire hydrant system and outdoor fire hydrant system. Indoor fire hydrant systems include indoor fire hydrants, water hoses, and water guns. Outdoor fire hydrants include two types of above-ground and underground. Outdoor fire hydrants are widely used in large-scale petrochemical fire-fighting facilities. Due to different installation conditions and different use sites, the petrochemical fire-fighting water system has adopted stable high-pressure water systems and fire hydrants. It is also gradually converted from a normal type to an adjustable pressure type fire hydrant. 3. Demolition tools, including fire axe, cutting tools, etc. As for the others, they belong to the fire protection system, such as automatic fire alarm system, automatic sprinkler system, smoke control system, fire separation system, fire broadcast system, gas fire extinguishing system, emergency evacuation system and so on. A fire extinguisher is a portable fire extinguisher that can be moved by humans. It can spray the fire extinguishing agent under its internal pressure to fight a fire. There are many kinds of fire extinguishers, and the scope of application is also different. Only by correctly selecting the type of fire extinguisher can effectively fight different types of fires and achieve the desired results. China's current national standards divide fire extinguishers into portable fire extinguishers and push-type fire extinguishers. The following is a brief introduction to the classification, application and use of portable fire extinguishers that people often see and come into contact with. Alarm class 1, fire detector The fire detector specifically includes a temperature-sensing fire detector, a smoke detector, a composite smoke-sensing fire detector, an ultraviolet flame fire detector, a combustible gas fire detector, and an infrared fire detector. 2, the alarm button The alarm button includes a manual fire alarm button and a fire hydrant button. 3, the alarm The alarm includes a fire alarm, a fire light alarm, and a fire sound and light alarm. 4, fire alarm controller The fire alarm controller includes an alarm host, a CRT display, a direct control panel, a bus operating panel, a power panel, a fire telephone switchboard, and a fire emergency broadcast system. Opical Fiber Concrete which is New, safety and high quality Optical Fiber Concrete,Fiber Optical In Concrete,Optical Fibers In Concrete,Fiber Optical Conctete Jiangxi Daishing POF Co.,Ltd , https://www.opticfibrelight.com
* Low-loss optical window in the light-visible area, and ability to transmit visible light from end to end, but not including ultraviolet or infrared light
* The impression given by traditional concrete is always murky, but this dark-colored, lifeless concrete may be about to become a thing of the past. combining traditional concrete with fiber optics cable can produce transparent concrete. Combining the fair-faced concrete technology with light-guiding materials, through product research, the light-transmitting concrete is made into garden building products, decorative plates, decorative blocks, transparent concrete bricks, wallboards, etc
* As long as the light is shining on one side of the light-transmitting concrete (monochromatic light or 7 color light), it will be able to see these lights (non-guided infrared light) from the other side of the concrete. These lights can be both chaotic and heavenly like the star in the sky; it also can be arranged in different shapes according to actual needs, such as characters, text, drawings, etc.. Because the concrete itself has solid, heavy-duty, thermal insulation, light and transparent materials, and concrete composite can be made into garden construction products, decorative plates, decorative blocks, can also be used to make a variety of building materials.
* Light-transmitting concrete has a good working performance and a wide application prospect, as follows:
- Light transmission concrete light guide material is evenly distributed and has good light transmission performance. It can transmit visible and infrared light of different wavelengths, which greatly saves the general architectural lighting loss. It is a kind of green and low carbon building material. Works of different textures and colors have significant architectural energy-saving and decorative effects.
- Light-transmitting concrete has good thermal insulation properties and is used in accordance with related materials. It can be used in indoor fire escape, night guidance, and other special fields, and improves the safety of buildings, especially high-rise buildings.
- Compared with ordinary concrete, the light-transmitting concrete's bending strength is greatly improved, and various shapes can be made according to building requirements, which expands the practicality and applicability of building materials.
- Light-transmitting concrete This type of wall itself has a high appreciation value. It has great potential for application in hotels, restaurants, villas, and other buildings that require decoration, and provides a material basis for further improving the architectural aesthetic effect.
* No conductivity or heat transfer(Through the fibers no electrical power is sent, they remain always cold )
* Reduced energy cost
* No electrical hazard
* Long life-time
