www.ssrlchemicals.com www.ssrlchemicals.com BLG Tablet is a battery life saver which prevents battery by early premature failure. It is used in electrolyte of free flooded conventional lead acid batteries. BLG Tablets contains Sodium sulfate anhydrous LR Grade Zinc sulfate anhydrous LR Grade Fumed Colloidal Silicon dioxide (Aerosil 200 a product of Degussa USA) Zonyl 1033D (Forafac a product of Dupont USA) Highly pure grade. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Sodium sulfate and Zinc sulfate is a white, orthorhombic crystalline stable compound, which does not decompose and does not react with oxidizing and reducing agent at normal and high temperatures. Sodium sulfate and Zinc sulfate are added to battery electrolyte to depress the formation of large lead sulfate crystals that are difficult to recharge. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Sodium Sulfate and zinc Sulfate increases the solubility of lead Sulfate while charging lead acid battery at lower acid concentrations due to the common ion effect.(Le chatleirs principle) It inhibits growth of large crystals i.e. called hard Sulfate, occurs by a dissolution precipitation process when the battery is on open circuit. At the low acid concentrations in a discharged battery the solubility of lead Sulfate is higher Most of the reputed companies in India and other countries are using Sodium Sulfate & Zinc Sulfate Tablets as a electrolyte additive since a long in lead acid Flooded and VRLA batteries. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com By addition of Aerosil 200 i.e. Fumed colloidal silicon dioxide in BLG Tablet, due to its thickening property of electrolyte it shows remarkable effect in electrolyte stratification.(Degussa technical literature usa) It is also used in preparation of Electro gel used in VRLA batteries, details as follows. Electrolyte Stratification: Acceleration due to gravity causes concentration gradient in the electrolyte from top to bottom of the cell in a flooded electrolyte lead acid battery. The concentrated acid sinks to the bottom and dilute acid raises to the top. This phenomenon is called acid stratification. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Acid stratification causes the top of the plate to Sulfate and lower portion to corrode and fail prematurely affecting performance and life of the cell. In Lead Acid Batteries the sulfuric acid has more density at lower portion of the plates while the upper portion are low in acid content and more dilute. The discharge process occurs at lower level of the plates while the charging process begins at upper portions of the plates on account of lesser Sulfation; lesser electrical resistance of plates and more solubility of lead Sulfate in water reach upper portions of the electrolyte. As a result of stratification of sulfuric acid-denser at the bottom, and weak at the top. The lower portions of the plates invariably get more Sulfated either during service or on idling. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Our experiments shows clear indications BLG Tablets prevents settling of acid electrolyte, maintains uniform density of electrolyte along the whole height of partition and all cells of Lead Acid Battery. The number one cause of mechanically sound battery failure occurs when lead Sulfate crystals turn abnormally hard and clog the plate surface, acid cannot enter the pores and starves to death. Sulfate occurs normally in lead-acid battery however during the charge phase some crystal remain, accumulated and harden between the plates to the point that normal charging will not break them down. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com In short colloidal silicon dioxide is insoluble in electrolyte solution it works externally i.e. while discharging smaller particles of colloidal silicon dioxide combines with the residue of lead sulfate, while reversible reaction starts i.e. charging colloidal silicon dioxide disintegrate that hard lead sulfate residue and helps to breaking them and dissolves in electrolyte solution. Addition of little concentration 0.1% of the effect of FORAFAC Zonyl 1033D (poly-fluoroalkyl sulfonic acid) as electrolyte additive on the performance of lead acid batteries. This additive has a surfactant character and its stability is increased by substitution of some hydrogen atoms by fluoride atoms in the molecule. With the use of FORAFAC Zonyl 1033D, the objective is to improve the life of lead acid batteries for standby & vehicle applications. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Comparative accelerated floating tests with and without FORAFAC zonyl 1033D have been carried out on standard AGM batteries. Batteries containing FORAFAC zonyl 1033D in acid at low concentration (0.1%) show a remarkable electrical behavior during the test. A good influence of FORAFAC zonyl 1033D on water consumption and on self-discharge is also observed. Results indicate that the life duration of lead acid batteries could be improved by a factor 1.5 to 2 with the use of FORAFAC zonyl 1033D . The mechanism of the FORAFAC zonyl 1033D action has been investigated and proved by many reputed companies. The use of the FORAFAC zonyl 1033D method appears to be a very promising solution in order to improve the behavior of lead acid batteries. For example, it is useful for applications at higher temperatures or to increase the specific energy of batteries by the utilization of thinner grid collectors and plates. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Forafac zonyl 1033 D is an anionic fluorinated surfactant. It reduces the surface tension of aqueous solutions to very low levels. Forafac zonyl 1033 D distinguishes itself by its exceptional chemical stability in corrosive medium and, in particular, very acidic solutions. it also act as a very low foaming agent. Forafac zonyl 1033 D imparts additional properties that may prove to be useful to any formulation based on aggressive (highly acidic, oxidizing, or reducing) media. Forafac zonyl 1033 D addition to lead acid battery & VRLA electrolyte recommended by researchers from CEAC,france (Now Exide). Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Above combination of BLG Tablets is designed to add to sulphuric acid electrolyte in lead acid batteries, it shows remarkable effect in following areas. Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com Shree Sai Research Lab. BLG Tablets www.ssrlchemicals.com By use of this battery performs consistent cycle-life, longer life & high coefficient of utilization. We had conducted more trials & test of the BLG Tablets on different models of various companies lead acid battery electrolyte in newly manufactured & old lead acid batteries shows the significance effect i.e. it increases the utilization of active material by dissolving lead sulfate into electrolyte & creates more porous structure in the plates for diffusion.
