4bs (Tetra Basic Lead Sulfate) For Positive Piate

4BS-Tetra Lead Sulfate “AddBATT Tetra L2 “for positive plate

این ادتیو شکلی ساختاری از سولفات سرب میباشد که با استفاده از آن در خمیر امکان تولید این ساختاردر صفحات کیورینگ شده با طول کریستال قابل کنترل و بسیار یکنواخت و همگن را فراهم میسازد و با تبدیل به Alpha–PbO2 در سطح مشترک خمیر و شبکه که ساختار اسکلتی دی اکسید سرب میباشد منجر به افزایش طول عمر باتری خصوصا در نواحی گرمسیری میگردد . این ادتیو بر خلاف محصولات سایر شرکتهای معتبر تولید کننده که بصورت محلول میباشد ، به صورت پودر ارائه میگردد که علاوه بر محاسن بسیار در پروسه حمل ، استفاده از آن را در فرایند خمیر سازی را بسیار راحت تر مینماید .

Necessary to increasing the life cycles ;

4BS (Tetra Basic Lead Sulfate, PbSO4.4PbO)come from PbO (Oxide of Orthorhombic Crystal Structure), it will become Alpha–PbO2 through a formation process which is better in life cycle.
Generally,a surface of positive grid in formed plate has a structure of Alpha–PbO2 and a surface of positive plate in formed plate has a structure of Beta–PbO2, because Alpha-PbO2 formed at an alkalinity circumstance and Beta-PbO2 formed at an acidity circumstance.
Specially, an oxide from Ball Mill has 100% of Tetragonal Crystal Structure’s PbO, it will become 3BS (Tri Basic Lead Sulfate, PbSO4. 3PbO) through Paste Mixing / Curing Process, and then it will become a structure of Beta-PbO2 through a formation process. Beta-PbO2 in positive plate has better performance than Alpha-PbO2 in positive plate.
But, Beta-PbO2 has lower life than Alpha PbO2 in positive plate. It needs 4BS as a seed of Alpha-PbO2 who use an oxide from Ball Mill Oxide Machine to make Alpha-PbO2 what has better life in positive plate. Barton Oxide has 5~30% of Orthorhombic Crystal Structure’s PbO according to an operation parameters, Orthorhombic-PbO will become 4BS through Paste Mixing / Curing (Hydroset) /Drying process.

Application :

[2-1]. To form Alpha–PbO2 in formed positive plate, 4BS need in unformed plate;
Generally, to create Alpha-PbO2 in positive plate :
a) High wet paste density in paste mixing.
– If a density is too high, it is not good for high rate discharge because of low porosity.
b) Low specific gravity acid for charging.
– If a specific gravity is too low, PbSO4 in unformed plate will dissolve easily in acid before charging process. An then, it will create a short circuit ( Dendrite ) due to hydration ( PbSO4 accumulate in a separator ) at separator. It will happen when a soaking time is too long at formation process.
c) Low temperature control at charging process.
-If a temperature is too low, a shedding will happen because cohesion of active material is lower due to an excessive Alpha–PbO2.
d) High temperature in a curing process.
– If a temperature is too high, an excessive 4BS will interrupt an initial performance.
[2-2]. When 4BS add in paste mixing process as a seed, 4BS will spread evenly in paste. Alpha Pb O2 will formed at a surface of grid, in the active material and a surface of plate through formation process.
[2-3]. A weight percentage of 4BS is 1~2% of oxide weight.
[2-4]. 4BS will has additive affect in curing time.
