Automatic determination of freezing point of foam extinguishing agent solution
Foam extinguisher is an effective extinguisher that can save flammable liquid. It mainly forms condensed foam floating layer on liquid surface, which plays a role of suffocation and cooling. Foam extinguishers are divided into chemical foam, air foam, fluoroprotein foam, water film forming foam and soluble resistant foam.
Foam fire extinguishing agent is mixed with water, through mechanical action or chemical reaction to produce foam for extinguishing agents. Foam fire extinguishing agent generally consists of foaming agent, foam stabilizer, viscosity reducer, antifreeze agent, cosolvent, preservative and water. Mainly used to fight fire of insoluble flammable liquid and general solid. Special foam extinguishers can also extinguish fires with water-soluble flammable liquids
The freezing point of foam fire extinguishing agent can be determined by automatic foam fire extinguishing agent freezing point tester, SH113E automatic foam fire extinguishing agent freezing point tester is designed and manufactured in accordance with the standard of the People's Republic of China "GB15308-2006 foam fire extinguishing agent", using a number of microcontroller main control components, Automatic refrigeration, automatic constant temperature, automatic detection, and automatically print out the results of the experiment required instruments
