Technical field
The present invention relates to a kind of nanometer of humic acid preparation and its applications in alkaline land improving, belong to the application of humic acid
Technical field.
Background technique
Humic acid is animals and plants remains, mainly the remains of plant, by the decomposition and conversion of microorganism and geochemical
A kind of organic substance that a series of processes learned are caused and accumulated.Its total amount is surprisingly big, and number is in terms of trillion tons.Rivers
Hu Hai, soil coal mine have its trace in most of earth's surface.Due to being widely present for it, so influence to the earth is also very
Greatly, it is related to the circulation of carbon, mineral migrate accumulation, soil fertility, the ecological balance etc..
Humic acid is the larger molecular organics matter being widely present in nature, and the basic structure of humic acid macromolecular is aromatic ring
And alicyclic ring, the functional groups such as carboxyl, hydroxyl, carbonyl, quinonyl, methoxyl group are connected on ring;Humic acid can be used for the soil in salt-soda soil
Improvement, but existing humic acid is usually the black powder of 60-80 mesh, i.e., partial size is 0.18-0.25mm, and partial size is larger, than
Surface area is small, and in soil improvement, usage amount is big, and improved effect is bad.
Those skilled in the art want the approach such as to reduce the partial size of humic acid, for example pass through grinding or crush always, but are grinding
Or crush when, humic acid powder be easy to agglomeration, it is tacky, lead to not be reduced to Nano grade.
CN107266690A discloses a kind of nanometer of humic acid potassium and its production method, by one of weathered coal and lignite
Or the mixture of two kinds of arbitrary proportions crushes, and is added to the water, and obtains suspension, and dispersing agent is added, then carries out cracking reaction, splits
Solution reaction temperature is 60 DEG C hereinafter, pressure is 15-20MPa, time 30-45min, grinds 5-15min after cracking, in suspension
Solid particle size is reduced to 2 μm hereinafter, potassium hydroxide is added, and normal-temperature reaction 30-45min obtains slurry, is spray-dried, obtained
To average grain diameter 100-500nm nanometer humic acid potassium.It needs that dispersing agent is added, and avoids reuniting;It is split using high pressure
Solution, then grinds, solid material partial size is reduced to 2 μm or less;Dual folded activating technology is recycled, by adding alkali to react, is extracted
Small molecule carbochain and middle microelement in raw material, small molecule carbochain generate shorter organic carbochain after reaction;Meanwhile having
