Chemical Additives

Being a leading firm in this industry, we are offering a high quality range of Lead Acid Battery Additive.

How BLG Tablets Work In Lead Acid Batteries:

• Common Ion Effects: BLG Tablet consists of sodium sulfate & zinc sulfate 
• Sodium sulfate & zinc sulfate are highly water soluble salts and they dissociate in water, producing sulfate ions
• Concentration of these salts have been kept at such level that conductivity is high and this helps electrical
• current to pass through it
• The addition of sodium sulfate & zinc sulfate Heptahydrate provides an inventory
• (excess) of sulfate ion that are available for more conductance
• The growth of larger crystals, called hard sulfate occurs by a dissolution precipitation process when the battery is in a discharged condition

Symptoms of Sulfated Battery:

• A General Lack of Capacity (Deliverable Power) 
• An Increase in Battery temperature while charging & discharging
• A strong Odor of Hydrogen Gas while charging
• An excessive use of water
• A rapid rise in battery voltage while charging
• A sudden drop of Battery voltage while discharging

High purity graphite is a kind of additive that is commonly used in lead-acid battery production.

Mechanism of action???

High purity graphite is made from natural flake graphite.

The graphite belongs to the hexagonal system with layered cleavage.

The attraction between the layers of graphite is small, other molecules or ions can be inserted into the layers.

Graphite has the high oxidation resistance and excellent conductivity.

It can be used in the positive and negative plates. Graphite can enhance the electrical conductivity of the plate,

improve the utilization of active material, prevent plate shrinkage, improve the charge and discharge performance of batteries.

Features:

1. 1.Deep processing of natural flake graphite, low impurity content.
2. 2.High decentralize, particle size uniformity.
3. 3.Increased battery capacity and high-current discharge performance.

Appearance: Gray-black micro-powder.

4.Improve charge acceptance performance.

Riding on unfathomable volumes of industrial expertise, we are engaged in offering a broad assortment of Paste Additive.

Other Details: 

• Time Consuming Procedure can convert into non-curing process could reduce production time and costs. The metallic lead content has to be reduced to below 2 wt.% or less after the curing process 
• A higher content of free lead may result in swelling, warping and/or extensive sludge formation during the formation of positive plates
• Main Benefit of SSCFP – Curing Free Paste Additive paste must be subjected to curing and drying processes during which temperature and humidity have to be carefully controlled.
• These processes are time consuming require considerable space and energy,and hence increase product cost.
• Furthermore, the resulting plates are rather rigid and stiff, which makes them suitable
• By use of SSCFP, a paste has excellent adhesion to the grids of a battery plate
• Directions for Use: For Curing Free Paste preparation Take 100 kg.of Blend Say 60:20 Ratio of Grey Oxide & Red Lead. Take 16 Lit SSCFP – Curing Free Paste Additive Solution and add slowly slowly into paste mixer up to 20 to 25 minutes.
• Paste temperature will go high upto 80 deg celsius.
• Then start Fan cooling to paste and add water to decrease temperature,( 4 BS Structure will generate in this step)After that Only Air Dry plates – Direct Group Assembly – Charging – Discharging – Ready
• Storage: Carboys of SSCFP must be stored in cool, shaded god owns free from dusty atmosphere and away from light and heat
• Persons handling this material must take the usual precautions of wearing goggles, rubber gloves and shoes
• Packing: 35 kg Carbo drum

We are reckoned entity of this domain engaged in offering an enhanced quality Tubular Positive Additive.

Other Details:

• The effect of addition of Tubular Positive Additive shows when the tubular electrodes were cycled, the capacity of the ground positive active material was gradually restored 
• Energy density of Active material & Cycle life increased as a function of the contact of Tubular positive additive
• The active material on the positive plates is mainly a mixture of lead oxide and Red Oxide
• In regular formulation, some of the active material will be underutilized due to non porous structure, Lack of Tetra basic lead sulfate Crystals Structure
• In order to achieve a porous structure with a high surface area for the electro-chemical process, the Tubular positive plates undergo a high temperature curing process to transform the lead oxide and lead sulfate into Tetra basic lead sulfate
• There is however limitations due to the large size of the Tetra basic lead sulfate crystals
• This can lead to a major disadvantage with Tetra basic lead sulfate namely a prolonged and higher electrical energy requirement for the formation of the positive plates and less surface area for the electro-chemical processes
• We suggest that after dry blend filling dip Tubular Positive electrodes in 1
• 150 Specific gravity of H2SO4 and then cured at 85 deg C for 4-5 hours in oven to form tetra basic Lead Sulfate crystals and alpha PbO2
• The tetra basic lead sulfate has sizes up to 3-20 micron
• Tubular positive additive leads into Uniform crystal size and increase in specific surface area
• The formation of a homogeneous tetra-basic sulfate crystal structure in the Tubular positive plates of lead-acid batteries is well known to offer significant electrochemical improvements in battery performance in respect of improved cycling and battery life
• By addition of Tubular Positive Additive a number of crystal seed sites are created, this leads to a large number of relatively even tetra-basic lead sulfate crystals
• It has been found that only a relatively short treatment of 3 to 4 hours is required to fully develop the crystal structure in the oven
• Without addition of Tubular Positive Additive in the blend Conventional method of Oven Chamber Heat Treatment Tetra basic curing process leads in the appearance of relatively large Tetra basic lead sulfate crystals
• Up to now it is has not been possible to control precisely the size of the final Tetra basic lead sulfate crystals
• The uncontrolled Tetra basic crystal growth leads to a reduction in the active surface of the plate
• A high specific surface area is demanded for good battery performance with respect to high current discharge capability
• The main feature of the Tubular Positive Additive is that the size of the final Tetra basic lead sulfate crystals can be controlled within the range from 4 to 15 µm

Stearic acid or stearin is used as a negative plate additive in the manufacture of lead-acid batteries. It is added at the rate of 0.6 g per kg of the oxide while preparing the paste.[11] It is believed to enhance the hydrophobicity of the negative plate, particularly during dry-charging process. It also reduces the extension of oxidation of the freshly formed lead (negative active material) when the plates are kept for drying in the open atmosphere after the process of tank formation. As a consequence, the charging time of a dry uncharged battery during initial filling and charging (IFC) is comparatively lower, as compared to a battery assembled with plates which do not contain stearic acid additive.
