CERAMIC FLAME ARRESTORS


INTRODUCTION
Zero-maintenance batteries have revolutionized the lead battery industry. One of the key components is a special ceramic filter disc. These are porous 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, they prevent the propagation/ ingress of flame from outside to inside by the use of a matrix of uniform openings that are carefully constructed to quench the flame. This provides an extinguishing barrier to the ignited flame.
Zero top-up: Small & uniform pores along with the water repellent properties prevents depletion of electrolyte through the pores.
Venting: Tailored pore size and pore volume ensures controlled venting of gases, heat developed especially during charging, preventing the build-up of gases that can otherwise lead to explosion.
Comparison Of Polymer Vs Ceramic Micro-Porous Filter Discs
- Porosity (%) of 45 + 5
- Uniform pore size of 150 – 200 microns
- Precisely tailored permeability as per customer requirements
- Very high strength with CCS values of 150 – 200 kg/cm2
- Very good acid resistance
- Excellent water repellency stable in acidic conditions
