Product Introduction
Hexafluorocyclophosphazene is a white to light yellow crystal mainly used as a flame retardant in lithium battery electrolytes, and can also be used in fields such as lubricants, semiconductors, or liquid crystal display substrates.
Application of Hexafluorocyclotriphosphazene
Transformer oil is the cooling medium for power transformers and a key material for ensuring power distribution. Transformer oil is generally produced from cyclohexane based crude oil, which has the best quality performance and the least tendency for hydrogen evolution, and is the basis for ensuring the safe operation of transformers. The occurrence of hydrogen evolution is a major threat to the safe operation of transformers. Therefore, how to minimize hydrogen evolution as much as possible, or even if hydrogen evolution occurs, it can be re fixed in gold transformer oil, is a technology that many companies and research institutes need to research and develop. Therefore, the CN117925306A patent provides an anti hydrogen evolution transformer oil.
Anti hydrogen evolution transformer oil includes 77-90 parts of base oil, 10-20 parts of alkylbenzene, and 0.03-0.5 parts of benzotriazole,0.4-0.6 parts of 2,6-di-tert-butyl-p-cresol, 0.03-0.4 parts of metal passivator, 5-10 parts of tetrahydrofuran, 1-3 parts of flame retardant, 5-10 parts of microporous mesoporous hydrogen absorbing particles.
The flame retardant can be one or more of hexaphenoxycyclophosphazene, hexafluorocyclophosphazene, hexachlorocyclophosphazene, hexamethoxycyclotriphosphazene, pentafluoro (phenoxy) cyclophosphazene, or ethoxy (pentafluoro) cyclophosphazene.
This patented technology uses solvent composite hydrogen adsorption particles. Firstly, hydrogen gas is precipitated during use and adsorbed onto transformer oil by tetrahydrofuran. The hydrogen gas adsorbed into the oil is further adsorbed and fixed by the hydrogen adsorption particles to prevent dissolution in transformer oil. The hydrogen adsorption particles used in the patent form a mesoporous microporous structure by controlling the pore size. By adopting a mesoporous microporous structure, not only can the pore volume be increased, but also the adsorbed hydrogen can be effectively fixed and retained.
