Come
to the miraculous humic
acid world
Humic
acid derived from animal and plant remains, mainly the
plant remains which effected by micro-organism and medium
and went through decomposition and composition change. It
is a kind of organic matter. The coal HA exist in the peat,
lignite and the brown coal. HA contain carbon, hydrogen, oxygen
and nitrogen elements etc., and aromaticnucleus, hydroxylgroup,
carboxyl, carbonyl, methoxyl active radical etc., these active
radicals lead to its weak acidity , hydrophily, ion exchange
, complexation, oxygen reductibility and biological activity
etc.
1.Classification of HA
According to the different existence, it can be divided into: soil HA, water HA, coalHA
According to dissolubility, it can be divided into: fulvic
acid, high active acid, humic
acid.
According to property, it can be divided into: original HA, regenerative HA, synthetical HA and BHA.
2. Application of HA
1).Agricultural field
Increase the yield of crops.
Enhance resistibility of plant.
Improve quality of product.
Increase performance of chemical fertilizer
Improve the soil
Activate nutrient of soil
Saving and holding water and droughtdefying
Stimulate the plant growth
Enhance the effect of pesticide and decrease toxicity
2).Industrial field
Concrete and ceramics
Mill run
Wastewater treatment
Mud adjuster in oil drilling
Purification and desulphurisation, organic matter
3.Other fields
storage battery cathode bloater
boiler treatment
food additive
medicine
fluid matter stability
environmental engineering
