Humic Acid

Humic acid is a kind of high polymer heterogeneous aromatic material contains hydroxyl, carboxyl, pjenolic hydroxyl and other active groups, it is weak acidity and insoluble in water but in alkaline. Humic acid is a powder or granular form of Leonardite/lignite, normally used as basic raw material for manufactures in Agricultureal and industrial.

1. Improve the soil structure,increase fertilizer efficiency, stimulate plant growth, enhance resistance of plants .

Humic acid is a natural macromolecular light aromatic acid substance, which is extracted from coal and prepared through appropriate physical and chemical treatments.Humic acid has a large specific surface area, is weakly acidic and electronegative, and contains a large amount of hydroxyl groups, hydroxyl groups, quinones and hydroxyquinone derivatives. It has good adsorption, ion exchange and complexing properties. Due to the existence of active groups, an exchange reaction is formed earlier than the passivation stage of lead during discharge, and is adsorbed on the front surface to prevent the formation of a dense, impermeable lead sulfate layer. Thereby significantly improving the low-temperature discharge capability and battery cycle life of the battery.

humic acid  is dark black humate derived from leonardite with high content of humic acid. When applied to soils it helps break compacted soils allowing for improved water penetration.For sandy soils, our humic acid adds essential organic material necessary for water retention and enhancing the sandy soil's ability to retain and not leach out vital plant nutrients.

1)High-quality humic acid coal is purified and finely processed through alkali dissolution, acid dilution, impurity removal and other processes to ensure the content and activity of active substances such as hydroxyl groups, hydroxyl groups, and phenolic hydroxyl groups that play a key role in humic acid.
2)Suppress negative plate passivation, improve battery capacity and low-temperature start-up discharge performance.
3)Improve battery charging ability and extend battery life.
4)Special for  batteries, high purity, few impurities
