IPNR Endura - Ceramic Flame Arrestor – Ceramic Filter Disc
Zero maintenance batteries have revolutionized the lead battery industry. One of the components is a special ceramic flame-proof filter disc. these are discs with perfectly tailored pore size and porosity, press fitted into the cap.
KEY FUNCTIONS
Flame Arresting:
In an event of sparking outside a battery, Endura`s Ceramic Flame Arrestors prevent the propagation/ ingression of the flame from outside to inside by its matrix of uniform pores that quench the flame. This provides an extinguishing barrier to the ignited flame.
Small & uniform pores along with the water repellent property prevents depletion of electrolyte through the pores. water vapour condenses and falls back into the battery.
Pore size is controlled by precise control of the grains used. Since bound formation is by sintering and not through fusion; the pore volume can be controlled precisely with minimal variation from batch to batch. The precise control of pore size allows tailoring permeability as per customer requirements. Porosity is maintained between 45-50%. Pore size is maintained between 150-200 microns.
Venting:Tailored pore size and pore volume ensures controlled venting of gases and heat developed during charging. Thus, preventing the build-up of gasses that can otherwise lead to an explosion
Acid Resistant:Endura`s Ceramic Flame Arrestors – Ceramic Filter Discs are formed by sintering at very high temperatures (1500°C), thus making them highly resistant to corrosive acids.
Strength:The crushing strength of Endura`s Ceramic Flame Arrestors – Ceramic Filter Discs is 150-200kg/cm2.
