The high-purity barium sulfate base can effectively increase the specific gravity of the storage battery, greatly increase the battery capacity and optimize the discharge efficiency; the ultra-low iron content fundamentally avoids the corrosion of the battery plate by impurities, reduces the risk of self-discharge, and makes the battery last longer.
✅Core Characteristics, Suitable for Full-Scenario Production
-
Excellent Dispersion: The powder is fine and uniform, with a precisely controlled particle size of 0.75~0.95μm. It can disperse quickly in lead paste, improve the utilization rate of active substances on the plate, and is suitable for various lead-acid battery production processes.
-
Stable Chemical Properties: It is a white powder with a relative density of 4.50. It is insoluble in water, ethanol and acids, but only soluble in hot concentrated sulfuric acid. Its stable chemical properties provide a reliable guarantee for the production process.
-
Stable and Controllable Quality: Each batch of products undergoes multiple rounds of strict testing, with extremely low impurity content and no difference in quality between batches, making production more worry-free.
✅Packaging, Storage and Transportation, Intimate Service Without Worries
To ensure product quality, we adopt standardized protective packaging: 25kg/bag, with an inner bag of polyethylene plastic film bag tied with a thread rope, and an outer bag of polypropylene plastic woven bag sewn by machine; customized packaging can also be provided according to customer needs.
For storage and transportation, it should be protected from exposure to sunlight and rain, stored in a dry and ventilated warehouse, and padded with a cushion to avoid moisture; it should not be stored or transported together with colored items, and handled with care during loading and unloading to prevent packaging damage.
🌟Choose the Right Auxiliary Material to Upgrade Battery Quality
Whether it is a new energy vehicle start-stop battery, an energy storage backup battery, or an industrial energy storage battery, our battery-specific barium sulfate can be accurately adapted, helping enterprises improve product competitiveness and create cost-effective, high-durability lead-acid battery products.
Choosing our battery-specific barium sulfate means choosing better battery performance, more stable production guarantee and longer product service life!
