Product Introduction
Guanidine carbonate is an extremely versatile organic synthetic raw material and analytical reagent, mainly used as a pH regulator, antioxidant, resin stabilizer, and soap for amino resins. It is also used as an additive for cement slurries and surfactants. It can also be used as a moisture resistant and synergistic agent for detergents, cosmetic raw materials, etc.
Application of Guanidine carbonate
Traditional fire extinguishing products are divided into Gaseous fire suppression, water-based extinguisher and dry powder extinguisher according to the type of extinguishing agent. These products require high-pressure drive to achieve automatic system startup, with a large number of accessories and high costs, as well as a high system failure rate. The existing hot aerosol fire extinguishing agents use pyrotechnic agents as thermal and power sources. Through the combustion of pyrotechnic agents, the hot aerosol fire extinguishing agent decomposes and produces a large amount of extinguishing substances, which are sprayed out together with the large amount of gas generated by the combustion of pyrotechnic agents, thereby achieving the purpose of fire extinguishing. Its disadvantage lies in the fact that hot aerosol fire extinguishing agents release a large amount of heat during combustion reactions, which may cause secondary combustion. In view of the inherent defects of the existing hot aerosol fire extinguishing system, the CN107854800B patent provides a simpler, safer and more efficient Automatic fire suppression composition, which can directly capture the fire situation and start fire extinguishing in real time without the need for front-end units such as detection and control. The Automatic fire suppression composition comprises three parts: main fire extinguishing component, gas generating component and adhesive.
The main extinguishing ingredients can be one or more of sodium bicarbonate, Potassium bicarbonate, Ammonium dihydrogen phosphate, Monopotassium phosphate, Manganese(II) carbonate, Potassium nitrate, Potassium bitartrate, Potassium sorbate, Potassium perchlorate, Potassium chlorate, Potassium permanganate, Sodium chlorate, Sodium perchlorate, Potassium dichromate, Potassium chromate.
Gas generating components can be one or more of 2-Cyanoguanidine, melamine, guanidine carbonate（CAS:593-85-1）, azodicarbonamide, Nitroguanidine, guanidine phosphate, Guanidinium chloride, urea, and Sulfamic acid guanidine.
The adhesive can be one or more of polyvinyl alcohol, acetal adhesive, hydroxypropyl methyl cellulose, phenolic resin, shellac, ethyl cellulose, nitrocellulose, or starch.
The Automatic fire suppression composition in this patent does not need to be equipped with a conventional detection and control unit, and does not need a startup device. In case of a fire, the fire extinguishing composition absorbs the heat generated in the fire field to conduct a flameless chemical reaction, generate gas and fire extinguishing substances, realize the Automatic fire suppression function, and is safe and reliable without secondary fire hazards.
