Abstract
The high-activity humic acid contains active humic acid 45-60 wt%, and has ash content 10-30 wt%, water insoluble matter less than 12 wt%, wtaer content less than 15 wt% and its pH value is 9-11. It is produced by using active leonardite in liquid state and through reinforced activation of various active radicals in humic acid and subsequent concentration and refining. Using the present invention can produce various humates, and the humic acid and its salts have high adsorption, high viscosity, good complexation and wide application range.
Description
The present invention relates to a kind of humic acids, particularly a kind of high-activity humic acid and manufacture method thereof.
Humic acids is the remains of animal, plant, decomposition and conversion through microorganism, and geochemical a series of process class larger molecular organics of causing and accumulating, owing to its physiologically active, adsorptivity, viscosity and complexing are widely used in compound manure, Industrial Wastewater Treatment, industries such as ore dressing, drilling well.。
Just begin humic acids is carried out systematic research from the fifties in the world, exploitation and production, mainly be to produce humic acids with " alkali-soluble acid analysis " method, though this method is simple, but because it is a purpose to extract common humic acids only, the activity of humic acids is not paid attention to, thereby limited Application humic scope and result of use.
The present invention aims to provide a kind of because of active high itself physiologically active, adsorptivity, viscosity and complexing so applied range, high-activity humic acid that result of use is good and the manufacture method thereof of having improved.
High-activity humic acid of the present invention, its component comprises activated humic acid, ignition residue, water-insoluble and moisture; Its pH value is 9-11, carboxyl-content (meg/g) 2.3 ± 0.1; Each components contents is by weight:
Activated humic acid 45-60; Ignition residue 10-30;
Water-insoluble :≤12; Moisture :≤15.
The manufacture method of high-activity humic acid involved in the present invention, its raw material comprises humic acids content 〉=50% and weathered coal, the high energy activation agent, the caustic soda of alkalinity 65% and ionized water, its proportioning raw materials is respectively by weight:
The weathered coal 15-16 of humic acids content 〉=50%; High energy activation agent 0.25-0.3; The caustic soda of alkalinity 65% is 0.72-0.8; Ionized water 132.26-148.82.
Its technical process is: the weathered coal of humic acids content 〉=50% that will be through pulverizing is poured basin into, injecting the ion water in the basin mixes, making its solid-to-liquid ratio is 1: 8 to 1: 9, again through screening, qualified slip enters settling tank, through shurry pump the slip that mixes is delivered to reactor, solid-to-liquid ratio was remained on 1: 8 to 1: 9, add caustic soda by ratio requirement again, pH value is at 9-11 in the control reactor, and stirring reaction 10 minutes pumps into another reactor with slip, divide the high energy activation agent that adds through proportioning for three times, with the activation humic acids, churning time is discharged into settling bath for whenever adding one time 10 minutes with reactant, in groove standing and reacting 24-36 hour, then through the 20-25 kilograms per centimeter
2Compressive reaction, again after air-dry or oven dry, pulverize and to reach required order number, packaging final prod.
In addition, utilize high-activity humic acid of the present invention, also can be made into high-activity humic acid sodium, high-activity humic acid potassium, high-activity humic acid ammonium, high-activity humic acid salts such as high-activity humic acid magnesium.
The present invention is except working hard on the content of humic acids, more pay attention to its activity, have that adsorptivity is strong, viscosity is high, complex performance is good, the advantage of applied range, but thereby utilize high-activity humic acid of the present invention and its esters production high-quality agriculturally, high-efficiency compound fertilizer, on Industrial Wastewater Treatment, be used to produce efficient water conditioner; In ore dressing, be used to produce higher optionally flotation agent; In drilling well, be used to produce multi-functional wellbore fluid; In ceramic industry, be used for enhancing, plasticising, dilution, bonding to pottery; On boiler compounds, be used to produce free of contamination high-performance scale inhibitor, on chemical fertilizers production, be used for the good coal of production bonding strength and hold in both hands caking agent; On feed, be used to produce active good mineral additive for feed.
